Bookbinding plant

The invention relates to a complete bookbinding system as well certain individual elements that build up this system.

Known bookbinding systems point to the implementation of the various Steps of tying up a number of different machines. The system can have a hot-melt adhesive binding device, a dresser, a device for rounding and backing, and a device for connecting Stiff book cover with the bound pages (a "wrapper" machine) is used to encompass. Usually work such machines are completely independent of each other and they are

309830 / 0-08

for processing only a certain size and "certain Book type determined, be it paperback * or book with stiff covers. Each device has to be of a certain size of the book running through the system, and if a book with a different size is to be produced, the system must be shut down in order to carry out a suitable conversion to be carried out on each individual device to be able to.

It would of course be desirable to combine all of these devices in such a way that an automatic bookbinding system that would allow loose pages or sets of sheets of the book to be grouped together and attached to one End of the system can be introduced and at the other end of the finished book with a cover comes out. but even if the various known machines were connected in series, the system would still be the have the above-mentioned disadvantages, namely that the entire system could only process one size and one type of book and that it would have to be switched off so that every single machine in the system can be used to produce the different types of book and large.

The object of the invention is to provide an integrated To create bookbinding equipment that is used to produce either "paperbacks" or books with stiff cover made from grouped together Pages or sets of sheets can be used and the

309830/0408

during operation an adjustment to different sizes the combined pages allows to produce books of different sizes without having to put down the system, whereby each of the associated devices must be adapted individually.

In addition, improved individual devices for the bookbinding system are to be improved which are a book truing device, a device for rounding and spine formation and a wrapping device having. If necessary, these devices can be used independently of one another with other known bookbinding devices to be used.

In particular, an uninterrupted, non-adjustable Apparatus for dressing books are created, which can be connected to any in the plant without interruption of operation Can adjust the introduced book size.

Finally, a device that automatically adjusts itself during operation is to be created for rounding and spine formation of the books, which can be used not only for books that consist of groups or "sheets of paper", but for books that are made using the so-called "perfect bookbinding" Method. ^v 'Perfect bookbinding "is a commercially used term for binding individual pages into a book by gluing the spine, as opposed to books that are made up of sheets of paper stapled together." Perfect binding "was recognized as an economical method of binding" paperback "

Books developed and one method was to use the books to glue on their back with a hot melt adhesive. This hot melt adhesive is a plastic that is a few degrees above its melting point is raised and then cools down quickly, which means that the books can be processed almost immediately

becomes possible. Until recently, perfect binding was used exclusively to make paperbacks ¹ , while books with stiff covers were made from stapled sets of sheets.

In the case of books with stiff covers, the The narrow side of the book is rounded and provided with a spine »and various attempts have been made so far to find the transfer the perfect binding technique to the binding of books with stiff cover, using synthetic resin adhesive or skin and bone glue was used. However, this made it necessary that the freshly glued books be piled up in racks Had to dry for several hours, after which they passed through the known devices for rounding and backing for processing stapled sets of sheets were intended.

Try to get books glued with hot melt glue with the help of the The usual devices for rounding and back formation have been unsuccessful. This is upon it attributed to the fact that the narrow side, if it has been shaped after the hot melt adhesive has cooled down, in a few

309830/040 «

Days to form their original flat shape again due to a property of the plastic called "memory". The device for rounding and back training can be used to process books, the spines of which can retain their rounded shape during the process stages "Rounding" and "Backing", which are carried out while the plastic glue is hot; Then it will be the adhesive is cooled in the desired formation of the back.

Another object of the invention is to provide a driving and installing device which does not rely on various Book sizes and thicknesses must be set but automatically during operation on books of different sizes and strengths and immediately connects the books with the covers and thus immediate further processing for completion who allows books.

According to the invention, the task is achieved by a bookbinding system solved, which has the following features:

The horizontally extending conveyor belts 25a and 25b keep the books in a stacked arrangement the band saw 43 in the dressing station of the bookbinding system. A plunger 24a may be required to Bringing a certain number of books into contact with the band saws. The band saws cut the books at their top Side, while the glued back rests on the conveyor belt 24. Then the books come to a table 26 and to two band saws 34, 36 where the two side edges of each book are dressed.

After this dressing station, the books, now designated B-2, pass over a heated part of the table 26, which preheats the book spine in order to soften the hot-melt adhesive - the book B-2 preparatory - into the device 27 for rounding and spine formation is introduced.

The self-adjusting book dressing device;

The dressing device shown in FIGS is a continuously operating, non-adjustable machine for trimming books. The device can adjusts itself automatically to each imported book size and does not have to be shut down if one of the books Large is switched to books of other sizes.

In Figure 2, books B-1 are stacked one behind the other Arrangement shown, with their glued back 32 received rest on the conveyor belt 24 moving in the horizontal direction and exit on the table 26. A pair with Vertically cutting band saws 34, 36 arranged at a distance from one another straighten the two side edges of the books. The band saw 34 is mounted on upper and lower disks 38a or 38b and the band saw 36 is guided over the upper disk 40a and a lower disk, not shown. The shit

309830/0408

ben 38a, b are rotatably mounted in a housing (not shown) which is arranged on the displaceable dressing frame or the carrier plate 41 (FIGS. 1 and 3), and the disks 40a are likewise mounted in a housing which is connected to the non-displaceable dressing frame or the carrier plate 42 (Figure 1) is firmly connected. The horizontally cutting band saw 43 adjusts the upper edge of the books and the saw is guided over the spaced disks 44a, b, which are rotatably mounted in a movable dressing frame or housing (will be described later) and by means of known drive means (not shown) are driven. The directions of the sawing path of the band saws 34, 36, 43 when trimming the sides, which are indicated by the arrows 34a, 36a and 43a, are parallel to the planes of the sides and perpendicular to the direction of their transport through the dresser.

contraption.

The cutting edges shown in Figure 2A, generally designated 46, are characterized by a plurality of teeth , each composed of the leading edge 48, which is arranged at a flat angle to the sheet guiding direction indicated by a double arrow 50 , and the rear edge 52, which is generally horizontal to the sheet guiding direction runs. As can be seen from Figure 2B, the surface of each tooth which touches the edges of the trimmed sides and is labeled 54 has no "slope",

309830/0408

226 433 €

i.e. the edge is on the same level as the best of the non-cutting surface of the saw blade that is in contact comes with the trimmed sides and is labeled 56.

. ·
The opposite surface 58 of each tooth that comes into contact with the trimmed material or edge 60 (Figure 2) of each side is beveled and meets surface 54 in a sharp edge.

ι ■ - -

The tooth construction of the band saws 34 ·, 36, 4-3 allows a smoothly separating the margin 60 of any desired width from the pages forming the books B-1. The edge material can be removed by means of suitable suction devices, for example by means of a suction hood (not shown).

Figure 3 shows the upper end of a book feed belt 25a (which is also shown in Figure 1) which exerts a pressure from the side on the side edges of the books B-1 in order to keep them to lead to the book dressing tape threads, as shown in FIG ist..The band 25a is arranged over vertically

in
Rolls 60, 62 guided, which are rotatably mounted in / the support plate 4-1 provided bearings, and a similarly mounted holle 66 (Figure 1) at the lower end keeps the belt tensioned and in connection with the side edges. Each of the rollers is with a conventional drive (not dargeetellt) connected to the belt in the direction of arrows · dee 68 to move horizontally ·.

309830/0408

The side edges of the books are also contacted by the probe 70 ″, which is in the form of an elongated rectangular strip and the top of which is bent out of the direction of book advance at 71, in order to avoid bumping into the passing books. A pair at a distance parallel of spaced pins 72, 7 ^ extend in the direction perpendicular to the surface of the sensor, which is not in connection with the cover edges. the pins are movably supported voneiander arranged in a Paarmit spacing bores 76 '78 provided in the stator 80 which in turn is received by the support plate 41. The plate 82 connects the ends of the pins 72, 74, opposite the feeler 70.

The plate 82 has in the middle an electrically insulated

on

strike 88 of a microswitch unit / »which also consists of opposing, electrically insulated stops 90, 92, which extend upwards from the base plate 94 firmly connected to the stand 80. The microswitch is located in the circuit of the electric motor 95 Rails or other suitable means (not shown) for horizontal displacement guided in a direction which is perpendicular ^to the direction of advance of the books. The direction of the

309830/0408

Movement of the carrier plate 41 is indicated by the arrow 96. From the carrier plate of the seat 98 protrudes which has a threaded recess for receiving the ^by: the motor 95 has driven threaded spindle 100th The rotation of the spindle moves the platen either towards or away from the books, depending on whether the spindle is driven clockwise or in the opposite direction.

The sensory feeler interacting with the above-mentioned parts 70 brings the band saw 34 into the exact position to the Separate the same margin width from the book pages B-1, whatever size the books within a certain area like to have. The setting is made continuously; it doesn't require the advance of the books for one Interrupt for a long time to readjust the band saw when the size of the books fed to the saw changes. The saw can be readjusted as follows:

When the size of the book pages that are guided past the measuring sensor 70 increases, the pages press sideways against the sensor and move it outwards, ie in the direction of the stand 80. This movement of the measuring sensor causes the centrally located stop 88 An electrical circuit is closed via the stop 90 and thus the motor 95 is switched on, which sets the threaded spindle 100 in a direction of rotation that is required to move the carrier plate 41 outwards and away from the book stream:

309330/0408

move. The band 25a and the band saw 34 also move horizontally to the same extent as the carrier plate Outward direction, both of which run over rollers that move together with the carrier plate in a horizontal direction move. As long as the books press against the probe 70, the electrical contact between the stops remains 88, 90 maintain and while moving the .Trägerplatte 41 to the outside. When the carrier plate is moved enough so that the side edges of the Books the pressure of the springs 84, 86 no longer the equilibrium hold, the stop 88 is released from the stop 90 and the motor 95 comes to a standstill.

Conversely, if the size of the books guided past the measuring sensor 70 decreases, the springs 84, 86 press this to a stop with the smaller books and thus effect an electrical connection between the central stop 88 and the stop 92. The motor 95 then drives the threaded spindle 100 in in a direction which is necessary to move the carrier plate 41 inward until the surface of the measuring sensor 70 facing the books and the book feed belt 25a are on the same plane , whereupon the microswitch interrupts the circuit.

The opposite band 25b (FIG. 1) and the band saw are guided over rollers which are rotatably mounted in the fixed support plate 42. The tape 25b and the

309830/0408

Saw 36 are consequently neither in the horizontal direction adjustable inwards or outwards, and when the size of the books that is introduced changes, the movable support plate 41 inwards or outwards until the tree between the two bands 25a, 25b is equal to the The breadth of the book of Strom is. \

On the non-displaceable support plate 43 there is also a switching device with a sensor and a microswitch the same construction and function as those of the sensor and microswitch in Figure 3 are provided. The 106 in Figure 1 designated switching device is arranged on the opposite side of the book stream and serves, so as long as it is closed, to interrupt the circuit connected to the sensor 70 in order to keep it as long as the Books are held firmly between the two belts 25a, 25b, to put inoperative. The switching device is intended to ensure that the belts 25a, 25b, once adjusted to the width of the books, do not shift outwards, when books coming out of the hot-melt adhesive binding device 21 abut the feeler 70 at 71.

FIG. 4 shows the means by which the horizontal cutting band saw 43 is positioned on books of various sizes. is set within a certain range. The adjustment means, indicated generally at 107, are similar to those shown in FIG. Touched in Figure 4

309830/0408

the probe 108 the top edges 109 of the books. It is secured by means of pins 110, 112 arranged at a distance from one another connected to the upper bracket 114. The one with the upper bracket 114- firmly connected housing 115 has a recess in which the knurled screw 116 is rotatably mounted, which engages in the \ threaded hole of the arm 117. With the arm 117 is a pair of spaced apart, electrically isolated ones Stops 118, 119 firmly connected, which are attached to a (not shown) electric motor are connected.

The one arranged centrally between the stops 118, 119 electrically isolated stop 122 is connected to the band saw housing 124, which is in the direction of arrow 126 by means of the by the last-mentioned electric motor driven threaded spindle 128 can be moved up and down. The disks 44a, b are rotatably mounted in bearings provided in the housing.

The bracket 1JO, which is fixedly connected to the housing 124, has Bores in which the pins 110, 112 are slidably mounted. The two compression springs 132, 134 under the Outriggers slid over the pegs push the probe 108 into contact with the books.

As with probe 70, the higher or lower determines Arrangement of the measuring sensor 108 the position of the upper dressing saw 43. If, for example, the centrally arranged Stop 122 is connected to the upper stop 118,

309830/0408

the electric motor drives the threaded spindle 128 into the one Direction of rotation that causes saw 43 and arm 130 to move downward.

The adjustment to the extent of the dressing of the books or the width of the end is made by suitable turns of the Knurled screw 116 causes. For a desired stronger dressing, the screw is turned in such a way that the upper Stop 118 is moved closer to the centrally located stop 122 and vice versa if less dressing is required is desired, the lower stop 119 is moved closer to the centrally arranged stop by means of the knurled screw.

When the books guided through the dressing device are to be provided with stiff covers, i.e. when there are If books with hard covers are involved, the setting means 107 shown in FIG. 4 are preferably set up by means of setting means at the outlet of the hot-melt adhesive binding device 21 added. The setting means are shown diagrammatically in FIG and include the probe 140 and microswitch unit 141, both of which are similar to those described in FIG. The probe 140, however, determines the thickness of each Book while it is being passed, as long as the books are in an end-to-end position and before they like are overlapped at 22.

309330/0408

The differences in the thickness of the books are due to the Microswitch 141 registered, which is electrically connected to the motor which sets the height of the upper band saw 43. However, these differences in thickness are first recorded by means of a suitable electronic storage system 142 Position of the upper band saw brought into effect when the books are under the saw.

With the help of the adjustment means described above, the thickness of each book determines the width of the tape, the above the sides is cut off by means of the upper band saw 43. The thicker the book, the more edge is removed with the saw and the lower the height (back to the upper edge) of the book (see distance 143 in Figure 2). In the opposite case, the thinner the book, the higher it is the saw is stopped and the greater the distance 143 will be. Provided that the "covers" or bindings, in which the books are attached, the same dimensions

the wise, is also the "clear width" or / with 144 in Figure

18 designated distance between the two side edges of the finished book and the side edges of the cover or Bindings be the same.

As can be seen from Figure 1, is immediately below the Rollers 66, 67 a pair of elongated guide pieces 152 or 134 arranged, which are initially bent outwards and starting at the same distance as the width of the books

are arranged from each other. The guide pieces 152 and 154 are firmly connected to the carrier plates 41 and 42, so that the distance between them is the size of the between them books passed through. The guide pieces extend in the vertical direction sufficiently beyond the carrier plates, so that a substantial part of the Side edges of the pages in between is touched.

The guide pieces 152, 154- do not align properly and to the feed direction of the tape 24 not in the right Books arranged at an angle. The guide pieces work as follows:

When a book is out of order on the belt so that one page reaches the leader 152 before the the other side reaches the guide piece 154, wird.erstere The side is no longer pushed by the belt 25a, while the latter side continues to be pushed forward by the belt 25b. The guide pieces also cause the books to be packed tightly are before they get between the saw 34, 36 because this provides the necessary back support for the dressing Books is achieved.

Up to this point the spines 32 of the books rested on the conveyor belt 24. However, if the books are guided through between the guide pieces 152, 15 ^ ·, they slide with theirs Back on the table 26. The table facilitates the production of the tight packing between the books, since on the one hand the

309830/0408

Side belts 25a, b and the conveyor belt 24 cooperate to the books close between the guide pieces 152, 154 · press, while the table 26 on the other hand, the necessary friction on the back of the books that means on the table of the conveyor belt 24 are pushed, causes.

The device for rounding and back formation

After the dressing, the books, now designated B-2 in FIG. 1, are passed over the table 26, which is the back preheated to soften the hot melt adhesive. The books are then separated by means of the conveyor belts 156, 158 and conveyed in series by the device 27 for rounding and backing.

As shown in Figure 5, books B-2 are labeled with downward facing back in the direction of arrow 158 by means of a pair of spaced apart, in horizontal Directional conveyor chains, generally designated 160 and 161 (Figure 7), through the device for Rounds and back training promoted. The conveyor chains 160, 161 are on the front sides and on the back sides of a every book. A pair of spaced apart rails 162, 163 (FIG. 5) run parallel to the direction of advance of the books above the chain 160 and like rails are arranged above the chain 161. Every pair of rails is in contact with the outer leaves on opposite pages of each book and is each with one

309830/0408

A plurality of pivotable levers 164 connected, whereby an optional horizontal adjustment of a rail relative to the others are made possible. The rails are used to support the top of the books when they are rounded or spined be provided.

Before entering the device for rounding and back training Each book first passes through a first station which is a heated platen 165 with a flat surface 166 has. The book then passes through a second heated platen 168 into a second station. The plate 168 has a concave, in Longitudinal depression or channel 170. A rounding wheel 172 is rotatably provided above the plate 168 in a pair of spaced-apart arms 175a, b, whose axis is arranged perpendicular to the direction of advance of the books. The wheel 172 is arranged to be Edge pushes down the top edges of the pages. Since the hot-melt adhesive in the back of the book is heated by means of the Plate softened and converted into a pliable state.

and

has been leading / giving way, the back can be in the shape of the Channel 17O are transferred.

Each book then arrives at a distance from one another. arranged spine rollers 174, 176 »178 in. a third Station. The outer surface of the backing rollers is concave formed, and a second wheel 180 is arbitrarily above one

309830/0408

Book is arranged and travels over the rollers to force the tops of the pages of the book around the spines in concave and convex formations as shown. The wheel 180 can be freely rotatably mounted in the arms 173a »b and its axes, exactly like the axes of the rollers 174» 176, 17Q, are perpendicular ^{to the} direction of advance of the books.

Above the rounding wheel 172 is the generally designated 181 Adjustment device provided. The setting device has the same structure as the setting device 107 in FIG 4- on and is used to indicate the location of the top edges of the to scan past books. The arms 173a, b are with the setting device 181 is connected in the same way as the saw housing 124 to the setting device 107 »so that a change in the books passing the setting device 181 a corresponding change in the position of the wheels 172, 180 evokes.

Behind the rolls 174-, 176, 178, the books come on one . Cooling plate 182, in the surface of which a concave channel 184 is designed, the shape of which corresponds to the spine of the books carried over it. The cooling plate hardens the adhesive that was previously by means of the heated plates 165 »168 as by means of the Table 26 has been plasticized.

The horizontal feed conveyor chains 160, 161 are shown in detail in FIG. 7 and cross sections thereof are shown in the figures

309830/0408

8 and 9- Books B-2 are grasped between the two chains and thereby guided in the direction of the arrows. Since the chains 160, 161 are the same, only one will be described. The chain 160 is guided over a pair of sprockets 186, 188, the input and output of the device for rounding and for Back formation are arranged and by means of suitable drive means (not shown) are driven. The chain exists of two sets of chain links 190, 190a arranged at a distance from one another, which are connected by means of pistons 191 and carry the freely rotating rollers 192, 192a with a slightly larger diameter knife. Likewise is the pressure member 194 · also arranged on each bolt 191.

Each pressure link has the rounded, book-holding surface 196 and is freely pivotable about the chain, so that it does not hold the book on first contact, as ^can be seen in position 200 (FIG. 7). The pressure member does not apply full pressure until its axis is in line with a line intersecting the axes of the sprockets 186, 187 (the line is labeled 202 in Figure 7) or before the rollers 192 are adjacent the pressure member in full. Come into contact with the pressure plate 204 described below. A very light spring brake or other means can be used to prevent the pressure members from swinging into an undesirable position during that part of the revolution in which they are not in contact with a book.

309830/0408

The pressure plate, generally designated 204, consists of two parts and is on opposite sides of the books above their passage through the device in which the Rounding takes place, arranged. It is composed of two parallel parts 206, 208 arranged at a distance from one another. A number of pin pairs 209 (FIG. 8) arranged at a distance from one another protrude from the inner part 206 and are slidably arranged in recesses provided in the other part. Spring elements., Such as the compression spring 210 are pushed over each pin and push parts 206, 208 apart. The outer part 208 is fixedly mounted, while the inner part 206 is only supported by the springs 210 and the pin 209 is held so that the latter part is pushed inwards.

The inner member 206 comes into contact with the rollers 192, 192a and exerts a slight inward direction on them Force out so that the compression members 194- light the books grasp while the fillet wheels 172 push the sides down into the concave channel 170. Since the books are only easy be detected, the rounding wheel 172 can easily the upper Press the edges into the desired rounded shape. Figure 8 shows at this point a cross section of the book and the Device and it is essential that the book is only slightly depressed by the pressure members 194.

A second pair of pressure plates 220 are on opposite one another

309830/0408

Pages of books arranged when they roll the spine 174, 1? 6, 178 pass. However, the pressure plate 220 is unlike the pressure plate 204, it is not spring-loaded but firmly anchored and exerts a greater pressure on the chain rollers 192, 192a, so that the pressure links 194 the books Grasp very tightly when the books are "backed" by means of the spine-forming rollers. Figure 9 shows one Cross-section of the book and the device at the point where the spine formation is carried out and it is essential that the lower part of the book in the area of the spine is replaced by the rollers, while it is by means of the pressure members 194 is supported. The mutual positions of the pressure plates 204, 220 can be continuously adapted to Books with different thicknesses can be set. The means by which this attitude is achieved are similar to those with which the horizontal position of the band saw 43 is set by means of the measuring sensor 140, microswitch unit and memory 142j and a detailed description thereof is deemed unnecessary. By means of the setting device, together with the setting device 181, the device receives for rounding and back formation a self-adjustment which is similar to that of the book truing device.

In Figures 6, 6A and 6B it is shown that the spine forming rollers 174, 176 and 178 taper towards their centers namely from a shallow taper at 174 at the entrance end to a steeper taper at 178 at the exit

309830/0408

end. More than three spine rollers can be provided and in this case the taper is between successive roles more gradually.

The rolls 17 ^ -, 176? 178 can be replaced or supplemented with rollers of different directions and configurations, as shown, for example, in FIGS. 60 and 6D.

As shown in Figure 60, the roller 230 is inclined Jacket surface that tapers in cross section from one end to the other. Above the outer surface is a number

in

Grooves 231 distributed, which run / direction of the roller axis. The axis of roller 230 can be disposed at any suitable angle, including oblique angles to both direction the advancement of the books B-2 as well as to the plane of the pages of the books passed by. The direction of the role is to be set in such a way that it is appropriate for the wheel of the desired "back formation". The role 230 would be in connection used with another such roll, with one roll placed on each side of a transported book is. Of course, a number of pairs of such roles can also be used. In Figure 6D is a Roller 232 is shown tapering in cross-section from both ends to the center. The matelflache of the role has a worm thread 234- and a suitable drive can be used to drive the roller in the direction of the book feed, at a speed that the outer surface moves a little faster than the advance of the books.

309330/0408

The worm thread will consequently exert an outward pressure on the surface of the book spine and thereby cause the pages to move towards the outer edges of the books. The worm thread of the role can too run in the opposite direction to the one shown. In this case, the roller is then driven more slowly or in opposite direction in order to generate the outward pressure that is necessary for the formation of the back to effect.

The sequence of the individual work steps carried out by the device shown in FIG. can be reversed. In Figure * 5, the rounding takes place before the Back formation. This is the preferred procedure, but it is also possible to do the backing before rounding.

The wheels 172 and 180 can be fixed and not adjustable or they can be adjustable. In Figure 9, the wheel 180 is made of resilient material such as rubber, and is on both sides by means of circular disks 236,238 edged. The threaded shaft 240 is inserted through an axial opening in the wheel and in the bearings of the Arms 173a, b rotatably mounted. The nuts 246, 248 are screwed onto the shaft and on opposite sides of the Arranged wheel. When the nuts are tightened against the washers 236, 238 they are pressed together more tightly, whereby the resilient material compresses and the curvature of the tread

of the wheel is reinforced. Conversely, loosening the

'UI q R 3 fl / Π Α 0 β

Nuts result in a flatter curvature of the wheel.

The curvature of the tread of the wheel can consequently be changed to accommodate books of different thicknesses to accomplish. Of course, any or all of the rounding wheels can be designed in the manner described be.

In Figures 10 and 11 a device for rounding is shown, which can be used instead of the one shown in Figure 5 and which can be arranged above or below the device for back formation. Books B-2 in Figure 10 pass first over a heated platen 250 having a flat surface and then onto a second heated platen 252, the surface of which has a longitudinal concave recess. The rounding wheels - _t 256 are arranged above the books.

Books B-2 are spaced from each other and between a pair of endless chains 258,260. The chains will pulled in the direction of arrow 262 by suitable sprockets (not shown), and as shown, each of the Chains a course parallel to the direction of the book advance. A reciprocal number of spaced cross bars 264 connect the chains and successive crossbars are spaced apart enough to accommodate a book in between. The cross bars grip the trailing edges of the

3098 3 0/0408

Books and convey them through the device. Any desired conveyor chains 160, 161 can also be used to facilitate training the one along the recess in plate 252 Book spines can be used.

An endless belt is positioned above and below each chain 258, 260. They have the reference numbers 266, 267 in the drawing. As shown, the belts run in one Direction that is parallel to the direction of book advance and they are over the rollers, one for each Band 266 and 267, which are designated in the drawing with 268 and 269, respectively. Suitable means are to drive the Roles provided.

Between the forward and backward part of each Belt 266, 267 are fixedly arranged pressure plates 270, 272, which are held by means of suitable (not shown) holding means and which press the inner part of each volume into contact with the books. The tapes therefore serve to keep the books in an upright position.

The automatic driving and installation device

FIG. 12 shows the knock-in device somewhat schematically. It provides the from the device to rounding and to the Spine on coming books with stiff covers. As shown in Figure 12, these are now labeled B-5

3 098 3 0/0408

Books on a conveyor belt 280 from the rounding and spinning device 27 to the main conveyor of the wrapping device brought. The main conveyor, generally designated 282, guides the books over the platen $ 28 (Fig 12). Wheels 383 and rails 383a that support wheels 172 and are similar to rails 162 can be used in any manner to connect the spines of the books to keep with the plate 283 and to prevent that bend the books.

The construction of the main conveyor is shown in detail in FIGS. 13, 14 and 15. The conveyor consists of two parallel Link chains 284-, 286 arranged on opposite sides of the books. The chain 284 is via sprockets 288, 290 out, which are arranged above and below the device. The bottom and top of the chain 284 is arranged parallel to the direction of advance of the books through the device. The chain is made by means of a suitable Drive means (not shown) driven so that its lower portion is in the direction of book advance (indicated by Arrow 292) is moved. The chain 286 moves in the same fashion.

A conveyor crossbar 294 is slidable in each segment of the Chains 284, 286 stored. The cross bars are horizontal to the chains and perpendicular to the direction of book advance arranged. As shown in Figure 15, each

309830/0408

Cross rod freely sliding and rotatably mounted in a recess, which is provided in the chain link segment 296. Your one end 298 can be in connection with the side wall of a The book and its other end is capped. The stop arm 301 protrudes in the vertical direction from the conveyor rod approximately in the middle between the chain link segment 296 and the rod end 298 out. Spring elements like spring 302 are across each rod between the chain link segment and the cap pushed and moved the conveyor crossbar in connection with a book, if not the The crossbar is held back by the interaction of the cap 300 with the stop 304 (described in more detail below) will. The spring 303 also holds the arm in a vertical position Position, unless it comes into contact with one of the boards 305 (Figure 14). The latch 306 is with the crossbar firmly connected and arranged within a corresponding recess 307 in the chain link segment 296 when the spring 302 is not held by the stop 304. The latch holds the stop arm 301 in a vertical position.

the two boards 305 are provided, / each horizontal and n> it is spaced outward from each of the two side walls of the books. The boards are in a something higher level than the book spine and are supported by suitable means (not shown).

A pair of spaced apart stops 304, 304a start near the top of the sprocket

309830/0408

286 at point 304b in Figure 12. The stops are open their length spaced from the link chains 284 and 284 respectively. The distance between the attacks varies

304b,. from a minimum at the ends / 304c to a maximum at about the middle of their ends.

The operation of the main conveyor 282 is illustrated in FIG Figures 13 and 14 described. Books B-3 are transported in the direction of arrows 292 by means of conveyor belt 280 (Fig 12) placed in a position where the conveyor crossbars 294 would normally be pressed against the books. Above of the main conveyor 282, however, the cross bars are prevented from doing so by the cooperation of their caps with stops 304. However, the stops on each side of the conveyor are against the Books angled down, causing the crossbars 294 to follow inside can be brought into contact with the books, since they are in a coordinated relationship with the books be transported. In this way the conveyor crossbars will grasp the books B-3 and support them as thick they may be.

Conveyor crossbars 294, spaced between successive books, are pushed inward until they touch, as in crossbars shown at 294a in Figures 13 and 13. In this position the cross have

309830/0408

rods 294-a two functions. Once push the cross bars the books B-3 over the platen 283 (Figure 12) and on the other hand grip their stop arms designated 301a (Figures 14 and 15) »the vertically in the space between the books and boards 305 are arranged (and in this position are held by the interaction of the locking lug 306 and the recess 307), a cover, as explained below. The stop arms on those conveyor rods that are in contact with the books (and that are not touch each other), are through the boards 305 on one held higher than the spine of the book.

As FIG. 12 also shows, there are a plurality of rigid binding covers 0 stacked on a conveyor belt 310, the is arranged in the horizontal direction under the platen 283, with the lid upright in the entrance end of the conveyor belt by means of a suitable bracket 312. The belt 310 conveys the lids in an upward direction inclined conveyor belt 314 ·, the one with a slightly larger one Surface speed as the tape 310 is running. By the interaction of the two bands 310 and 314 · together with a conventional insertion control mechanism 316, which rests on the lids ^ causes the lids about Stacked like a pyramid against the upwardly inclined suction belt 318 are. The space between the mechanism 316 and the adjacent area of the tape 318 is just large enough to allow the passage of only one cover G on one time.

309830 / CU08

The lids C are sequentially guided upwards by the suction belt 318 and onto the surface of a third, upwards inclined conveyor belt 320 placed it on the surface a horizontally disposed conveyor belt 322, the surface of which is generally flush with the surface the platen 283 is located.

Each book is conveyed to the conveyor belt 322 by means of the cross bars 294-a resting behind the book. Regarding FIG. 12 shows that the leading edge 324 of a book, which is about to come into contact with the tape 322, is laterally slightly behind the leading edge 326 of the cover, which is also about to make contact with the belt 322. The book will therefore be on tape 322 above cover C. Of the Main conveyor 282 runs slightly faster than conveyor belt 322 so the book catches up with the cover. The lid will originally promoted by means of both belts 320 and 322 and then by means of the abovementioned stop arms 301a, when the Lid is completely on belt 322. The stop arms adjust the cover and book correctly to one another, so that the cover overlaps the top and bottom of the book equally spaced.

As stated, an exact end-to-end position of the Reached socket B-3 on the cover G by means of the downwardly directed stop arms 301a. The exact side-by-side position of the book on the cover is by means of the stops 326, 328

309830/0408

which are located near the exit end of the main conveyor 282. The attacks 326,328 are schematic

shown in Figure 12 and more precisely in Figures 16 and 17 · How shown consists of the stop 326 from an upper part 326a,. which is angled inwards at an oblique angle to the direction of book advance and merges into the lower part 326b, which is parallel to the feed direction. The stop 328 is the game gel image of the stop 326.

The stops 326, 328 are connected at their lower edges and below the upper area of the conveyor belt 322 (FIG. 12) to the projections 330, 332 (FIG. 17), which are mounted on bushes, whereby they freely move onto pins 334, 336. and can slide, the latter being fixed by suitable means perpendicular to the direction of book advance. The arms 338, 34-0 are pivotally connected at one end to the projections 330 or 332 and at the other end to one end of the central pivotable arm; 34-2, which by means of a suitable spring element in the direction of the arrow 34-4- is energized to push the stops 326, 328 inward. The central axis 34-6 of the arm 34-2 is journalled just below the center of the path of the books B-3. ^:

The stops 326, 328 always move simultaneously and are always the same distance from the center of the path of the books. The stops pressed inwardly into contact with the side edges of the lids C ensure that the lids are in a

309830/0408

Side-by-side relationship with the books can be averaged.

As can be seen from Figure 16, the connection of the cover G produced with the books according to the invention by means of an adhesive either on the inner surface 348 of the lids or on the front and back sides 350, 351 of the Books is upset. The adhesive is applied beforehand using suitable means (not shown) and can dry ^ before the books reach the wrapping and installation device. Suitable adhesives are those that are made by means of heat or by a Solvents can be reactivated. The former include those made of polyvinyl acetate, polymeric resin, and Polyethylene and paraffin wax are made. Figure 16 shows Means by which a solvent can be applied to reactivate an adhesive either on the surface 348 or 350 »351 has been applied.

As shown in FIG. 16, vessels 352, 35, 4 are firmly connected to the outer wall of the stops 326, 328. Tubes 356, 358 provided with bores are slidably connected to the vessels and penetrate openings in the stop walls and end in enlarged feet (only one shown and designated with 360). Suitable spring elements, which are arranged, for example, in the vessels 352, 354, press the feet into contact with the opposite pages of the book and the entrance ends of the feet are bent outwards so that they can be divided by the books that are brought up. In this way the length of the with holes

309830/0408

provided tubes 356, 358 always to the width of the cover G set because the self-adjusting stops 326, 328 and the thickness of the book will determine the length of the tube protruding from the storage jar.

The solvent is removed from the vessels 352, 354- from a suitable one central source and the liquid is sprayed onto the upper inner wall 34-8 of the lid as shown.

If the adhesive applied to the cover or the books is reactivated by means of heat, then the reactivation device can the same as that shown in Figure 16, except that instead of the solvent, hot air from the holes provided pipes 356, 358 flows. The self-tuning of the pipes would not be affected by such a change.

Below the tubes 356, 358 provided with bores, unfolding devices 362, 364 are provided, between which the Books are passed through. Below the link chain 282, the books are spaced apart by means of Conveyor chains, one of which is shown and denoted by, carried. These chains are described below. The entrance end 362a of the unfolding device is generally horizontal and level with the surface of the conveyor belt 322 (Figure 12). Below the entrance end 362a, the outer edge of the unfolding device gradually slopes inwards and upwards at their exit end 362b (Fig

309830 / (Η08

18), which is arranged above the belt 322 in the vertical direction. The unfolding device 364 is the mirror image of the unfolding device 362. In the course of the passage of the books and covers between the unfolding devices 362, 364 the lids are raised from a horizontal position to a vertical position, as shown in FIG.

The one now marked with B-4 in FIG. 18, with a lid provided book now passes between spaced-apart stops 364, 366, which are the same Construction like the stops 326, 328 and resiliently according to the same means as with the stops 326, 328 inside so that the outer walls of book B-4 with the adjoining rear walls of the stops 364, 366 come into contact.

The stops 364, 366 are used to adjust the mutual positions of the pressure roller units generally designated 368, 370 by means of a microswitch unit, indicated generally at 372, which is connected to a stop. As shown, the unit 372 consists of a stop 37 ^ » which is arranged between a pair of parallel stops 376, 378, which are connected to the base plate 380 of the pressure roller unit 368 are firmly connected. The unit 368 can be displaced perpendicular to the feed direction by means of rollers 382, 384, which are attached below the base plate and run in guide rails 366 and 388, respectively. The unit 370 is similarly

309830/9408

sliding. The motor 390 engages a threaded spindle 391, which has a left-hand and a right-hand thread. One thread 392 engages in the internal thread of a recess in the base plate 380 one, while the other thread 394- equally with the base plate 396 of the unit 370 for setting the relative positions of the units is screwed.

The microswitch unit 372 operates in the same way as the unit shown in FIG. 3, relative to one another Maintain the intended positions of the pressure roller units so that they apply the same inward pressure exercise on the books passed between them, regardless of the thickness of the books. For example, if in FIGS. 18 and 19 a stop having contact 374 364 moves outward, becomes an electrical connection produced with the stop 378, which closes the circuit, and the motor 390 switches on, which the spindle 391 set in rotation in such a way that the pressure roller units 368, 370 move apart.

The pressure roller unit 368 consists of a pair of rollers 4-00, 402, which are rotatably mounted in the base plate 380 and the cover plate 404 by means of shafts. The print tape 406 is over The rollers are guided and can have a covering made of resilient material, such as, for example, foam rubber or plastic.

The band can also consist of spring-loaded pads in

^ D9 830/0408

Band shape exist. The tape is' by means of suitable (not shown) drive means driven. The pressure roller unit 370 has the same structure as that described above Unit 368 on.

The pressure roller units 368, 370 press the solvent ge ran ten or heated ceiling C against the outside walls of the book to bring about the complete connection of the ceiling with the books and thus to complete the wrapping process. If a heat softening adhesive is used, it can be softened by the heat transmitted from the printing tapes. In such a case, the adhesive may _v ultrasonic devices or other suitable means are heated by means of heating plates. If the rollers are heated as described, the tubes 356 provided with bores and the device connected to them can be omitted.

The means by which the paving is carried out are explained with reference to FIG. The operation is used to create a Notch or "fold" across the front and back surfaces of the lid close to and parallel to the spine. In Figure 12 is a pair of spaced apart conveyor chains (shown and labeled 265) provided on opposite pages of books B-3. The chains have parallel book feed trains that run parallel to the Book feed are arranged and which begin near the entrance end of the stops 326, 328 and at the printing units

309830/0408

368, 370 ends. A pair of spaced apart rails 4-02 are mounted above each roller and contact the opposing cover walls, and a plurality of strands 404 with axes perpendicular to the direction of book advance are disposed above the printing plates. The chains 265 &&& ^ ie rails 402 have the same structure as the chains 160, 161 and the rails 162, 163 (FIG. 7) and the wheels 404 have the same structure as the rounding wheel 172 (FIG. 5). The pressure links of the chains 265 (corresponding to pressure members 194, Figure 7) are pressed into contact with the books by means of pressure plates of the same structure as the pressure plates 220 (Figure 7). The pressure members touch the books at the same point as the pressure members 194 shown in Figures 8 and 9. However, the pressure plates apply a considerable inward force to the books to cause the pressure members to form a distinct indentation or fold in the covers. The position of the pressure plates can be adjusted to the thickness of the books passing between the chains 265 in the same manner as the pressure plates 220.

If the lids are attached by means of an adhesive that becomes softened by heat, the pressure links can be sufficiently tightened high temperature so that the glue remains in a soft state. In this case it may be advisable to To provide means to rapidly cool the lids at the seam and cooling rods 408 can be used for this purpose.

309830/0408

The cooling rods 4-08 are arranged at the exit of the chains 265 and lie on the same line with the pressure links in the lines of the chains. The chains hold the books between them the bars so that the bars are arranged in the gaps. Since the bars are chilled, they harden the glue nearby of the fold and securely attach the covers to the books.
