18 Claims.

Our invention is a method of and apparatus for incorporating a pull in a package for facilitating the opening thereof and preferably for initiating the ejection of an article enclosed therein, and our invention is particularly adapted for the production of a cigarette package invented by Bernard J. Tamarin and of the type illustrated in his application Serial No. 467,676.

In accordance with our invention, a pull, such as a strip of tape, is overlaid by a wrapper and the wrapper is formed into a container for a group of articles, such as rows of cigarettes. The pull is preferably attached to one or more articles of the group or to the wrapper or to both wrapper and article, and portions of the wrapper may be bent to form an end closure having a member around which a pull section is so looped that a pull thereon unfolds such member to expose an end of one or more of the enclosed articles.

Preferably the pull is anchored to at least one of the exposed articles so that a continued pull on the pull after the opening of the closure member causes the attached article to rise until the point of attachment of the pull to the article clears'the wrapper, whereupon the pull is stripped from the article and the latter is left projecting from but positioned by the remaining articles of the group encased in the wrapper.

The wrapper and pull are preferably fed to a suitable support for positioning them relatively to one another during the overlaying of the pull by the wrapper and the formation of a container from the wrapper around the pull and during the insertion of a group of articles into such container.

Preferably each pull is out from a strip of multi-ply cellophane tape which is longitudinally creased to impart thereto a tendency to assume a channeled cross section which stiffens the tape longitudinally to facilitate its rectilineal movement transversely to the path of a strip of sheet material from which a Wrapper may be cut substantially concurrently with the severance of a pull from the tape strip. The creased and channeled cross section of the pull further facilitates the attachment thereof to one of the articles enclosed in the container; such attachment preferably being effected after the ejection of the container and its contents from the support on which the container is formed.

Each wrapper is preferably pre-slit along converging lines diagonal to one edge. The portion of the wrapper containing diagonal slits forms a container margin providing tuck and fold extensions projecting beyond' the ends of the articles housed in the container, andsuch marginal portion is tucked and folded down transversely to the body of the container to form an end closure including a member about which an outer portion of the pull is looped; to which the pull is preferably attached, and from which the terminus of the pull projects laterally. Preferably the end closure member about which the pull is looped consists of a tuck, which is partly overlaid by minor sections of folds which are severed from the major sections of such folds by the diagonal slits in the marginal portion to facilitate the subsequent unfolding of the minor fold sections by rise of the tuck covered thereby when it is lifted by a pull on the pull looped thereon. The major sections of the folds are secured by a stamp or the like adhesively attached to the front and back walls having an edge slightly overlapping the diagonal edges of the minor fold sections to yieldingly hold such minor fold sections in closed positions.

At any stage in the proceedings, and preferably at an early stage, the end of the container remote from the pull terminus may be closed in any desired manner, and the container formed by the wrapper may be sheathed in a label jacket. After both ends of the container are closed, it may be enveloped in a cellophane covering or the like to provide a package similar in general appearance to standard cigarette packages.

When our invention is utilized in connection with the packaging of cigarettes or analogous articles, the pull is preferably attached at a point along the middle portion of a cigarette which is spaced from the wrapper by adjoining cigarettes so that the inner portion of the pull lies in a channel between the cigarette to which the pull is attached and the wrapper; such channel preferably being bounded laterally by end cigarettes of rows on opposite sides of the cigarette to which the pull is attached when the cigarettes are arranged in rows 1-6-1. However, the pull may be attached to an end cigarette of a side row and lie in a channel between such cigarette and a corner of the package when the cigarettes are arranged in rows 1-1-6.

The pull is preferably attached to the cigarette by means of an adhesive applied thereto before the group has been fully housed within the wrapper. We have found it advantageous to apply the adhesive to an end cigarette after the group has been assembled and preferably after it has been partly inserted within the container formed by the wrapper, and to then complete the insertion of the cigarette group into the container while the pull strip is out of contact with the adhesively coated cigarette and thereafter to press the pull strip into contact with the adhesively coated section of the cigarette.

While our method is capable of practice manually, it is particularly applicable to providing pulls for packages durin their manufacture on standard types of cigarette packaging machines having a turret for forming sequential containers and mechanism for grouping and compacting cigarettes and filling the respective containers therewith immediately after completion of the containers. Our invention embraces apparatus hereinafter described whereby the steps of our method may be rapidly carried out during the formation and loading of a container to produce asealed package having a pull for opening it and initiatin the ejection of its contents.

The principles and characteristic features of our invention, and the manner of practicing our method and of making, constructing and using our apparatus will further appear from the accompanying drawings and the following description explaining the best modes in which we have contemplated applying such principles.

In packaging cigarettes, for example, in accord.- ance with our invention, we preferably form an inner shell of the package from g, rectangular wrapper I having spaced slits 2 and 3 extending diagonally inward from an edge of the wrapper and converging toward one another. Such wrappers may consist of any desired type of sheet material but are preferably made from strips of laminated paper and metalfoil.

In making a wrapper, alaminated strip is preferably cut to form the slit 3 before the severance of the wrapper from the strip, and the strip is then cut to simultaneously form the slit 2 and sever the wrapper from the strip.

The slitting and severance of a wrapper may be performed in any desired manner but is conveniritly effected, as shown in Fig. 17, by feeding a laminated strip 4 in the path of a cutter 5 having' short diagonal end blades 6 and 1 and an intermediate long blade 8. When the laminated strip and cutter are brought into cutting relationship, the blade 6 cuts a diagonal slit 3 in an unsevered section of the strip 4; the blade 8 severe a section from the strip 4 to form a, wrapper I, and simultaneously with such severance the blade I cuts a slit 2 in the wrapper I being severed; such wrapper I already containing a slit 3 cut during the severance of a preceding wrapper.

In the practice of our method, we preferably utilize a hollow support or former 9, one end of which is seated in a hollow block or bracket I forming a peripheral rim about one end of the former 9. The rim ID has a beveled nose H which extends over one of the narrower faces 9a of the former 9 and contains a slot l2 extending longitudinally of the former and having a bottom inclined downwardly toward the surface of the face 9a. The inner end of the inclined bottom of the slot I2 is separated from the surface of the face 9 by a short step 13. The rim l0 and former 9 contain a through aperture I4 having its mouth in the bottom of the groove l2 adjacent to the step I3.

In the preferred practice of our invention, a strip of longitudinally creased pull tape 15 is projected through the slot l2 and over the surface 9a at or about the time a wrapper l is positioned in the path of movement of the front or leading surface of the former 9, a shown in Fig. 2. The

free end of the projected tape rests on the surface 9a. near the end thereof opposite to the step 13 and the section of tape adjacent to the top of the step I3 is spaced from the surface 911 a distance substantially equal to the height of the step IS. The tape is then severed adjacent to the mouth of the former to leave a pull l5 resting in the channel l2 and on the surface 911.

The wrapper I, with the slit 2 above the level of the surface 9a, is bent circumferentially around the former 9, as shown in Fig. 3, so that the slits 2 and 3 are in substantial alignment on opposite sides of the former 9. One edge of the wrapper l is adjacent to the bottom of the step I3, and when the wrapper I is drawn tightly against the surface 9a, the projecting end 15a of the pull [5' is bent by the step l3 at right angles to the surface 9a and to the tape section resting thereon, thereby uncovering the mouth of the aperture I4.

The juxtaposed transverse edges of the wrapper 1 may be adhesively connected to form a seam l6 and the portion of the wrapper l projecting beyond the end of the former 9 may be tucked and folded in any usual manner to form a bottom closure for the soft shell thus formed from the wrapper l.

A tacky adhesive is applied by any suitable means, such as an applicator IT, as shown in Fig. 4, to the side surface of the soft shell in alignment with the bent end l5a of the pull l5 and preferably on the end extension of the shell from'which the top closure will be formed.

If it is desired that the shell be sheathed in a printed jacket, a second wrapper or label l8, of somewhat less width than the wrapper I, is applied to the shell on the former 9, as shown in Fig. 5, so that the inner edge of the label 18 leaves exposed the adhesive drop applied by the applicator l1. When the-label or wrapper l8 has been bent circumferentially aroundthe shell to form a jacket, the projecting pull Strip section I5a is folded down against the end extension of the shell and against the jacket by any suitable means, such as a folder [9, and the folded end 15a of the pull is lightly tacked in place by the spot of adhesive previously applied by the applicator H.

The outer end of the label or wrapper [8 may be tucked in any usual manner, as for instance by tuckers 29, and the flaps between the tucks then folded and secured together. By combining the shell and jacket there is provided a double walled pouch having a pull extending along the inner surface of the shell and overlying and tacked to the outer surface of the shell, as shown in Fig. '7.

A bundle of cigarettes 3| is inserted in the open, flared mouth of the former 9 with the pouch thereon; the bundle preferably being preformed and composed of two outer rows 3m and 3"), each containing an odd number of cigarettes, and an intermediate row 310 containing an even number of cigarettes. The end cigarette 310' of the intermediate row 3lc forms the bottom of a shallow channel lying between the end cigarettes of the outer rows 3 la and 3 lb.

A spot 32 of adhesive is applied intermediate the ends of the end cigarette 3lc before the bundle f cigarettes is fully seated in the soft shell or pouch formed by the wrapper l, but preferably after a group of cigarettes have been assembled in a bundle.

This adhesive spot 32 is preferably applied to the cigarette at a point along its length such that when the cigarette is shifted lengthwise to bring its spot adjacent to the fold line between the pouch and its tuck, one end of the cigarette will project from the pouch sufficiently to be easily grasped, whereas the other end of the cigarette will be so far down within the pouch as to firmly position the cigarette. On a cigarette of ordinary length, the spot is preferably on the intermediate half of the length of the cigarette, that is at a point not less than one-fourth its length from either end, and an advantageous position is a point spaced from its outer end approximately two-fifths the length of the cigarette.

The spot of adhesive 32 may be conveniently applied to the cigarette 310' at the desired point by inserting the adhesively coated end of an applicator 33 (Figs. 9 and 10) through the aperture [4 in the former 9 when the outer end of the cigarette bundle is aligned with the outer edge of the mouth of the former.

The cigarette 3 I0 is positioned by engagement in the grooves between the two upper cigarettes of the respective rows 3: and 3|b (Figs. 10 and 15) and its peripheral surface is thereby held in spaced relation from the inner face of the former member 9a (Fig. 10). Hence the bundled cigarettes may be pushed as a group through the former 9 without contact of the adhesive spot 32 with the inner face of the former or with the inner face of the pouch when the latter is detached from the former.

The application of pressure to the outer end of the cigarette bundle will force the cigarettes through the former 9 so as to first seat the inner ends of the cigarettes against the bottom of the pouch and then discharge the pouch, with the cigarettes therein, from the former 9, as shown in Figs. 11 and 12.

This longitudinal movement of the pouch slides the pull l5 along the former'member 9a without longitudinally crumpling the pull. The portion 7 of the pull lying within the ejected pouch tends to resume its channel-like cross section and drop into the channel formed by the cigarettes 31a and the end cigarettes of the rows 31a and 3112 on either side thereof.

After the filled pouch has been ejected from the former 9, the projecting end sections Ia and lb thereof (Fig. 11) are tucked manually or by conventional tuckers 35, as shown in Fig. 12. The tucking of the section la, to which is attached the exterior section I5a of the pull, preferably brings this section l5a into the effective zone of an electric eye 35a in a circuit preventing the subsequent operation of a conventional throwout mechanism or alarm, and which are actuated in the absence or displacement of the pull section [5a.

When the extensions la and lb have been tucked, the side extensions to and id (Fig. 14) are folded over the tucks and over a portion of the pull section overlying the tuck section la and secured by a stamp 37.

It is preferable that the sections la and lb be tucked before the sections and Id are folded,

as shown in Figs. 12 to 16, but it will be understood that the top extensions may be first folded and then tucked in the same manner as the bottom extensions, as shown in Figs. 3 and 4, or the top may be closed by first tucking one extension, then forming one fold, then tucking another section, and then forming a second fold, or by other combinations of tucks and folds, but none of such closures are as effective as having the tuck section la overlaid by a-pair of folds.

To insure adhesion of the -pull to the cigarette lo by the adhesive spot 32, the edge of the pouch may be bulged inward, as for insta-nce'by a presser finger 36, so as to press the pull firmly into contact with the-adhesive spot and hold it there until such spot has solidified, as shown in. Figs. 15 and 16. The package is then further sealed by pasting a stamp 31 over the fold sections lo and Id so as to overlie the now intersecting cuts '2 ands therein.

To open the packa e'and eject a cigarette, it is only necessary to pull on the pull section 15a laterally of the package. The pull on the pull draws the tucked section I a upward and outward and crumples it, thereby displacing the fold sections to and Id from beneath the stamp 37', and drawing the cigarette 310 upward. As soon as the rise of the cigarette '3lc' moves the spot '32 above the crumpled tuck section la, the lateral stress on the pull l5 strips it from the cigarette 3|c by a splitting action without defacing thecigarette, which is left projecting part way from the package but with its remainder held by its engagement between the cigarettes Of the end rows and prevented thereby from dropping. I

The steps of our method maybe manually performed but may be more rapidly and efficiently performed. by our improved apparatus, which is adapted for cooperation with standard types of high speed cigarette packaging machinery.

The drawings show an embodiment of our apparatus invention, which we have illustrated by way of example, in cooperativerelation with the well-known American Machine and Foundry Company cigarette packer of the type illustrated generally in United States Patent No. 1,926, 1Q2 of September 12, 1933.

For the sake of simplicity. we have shown only enough of a conventional-packer per 'se. to facili. tate an understanding of the positioningxand ooaction of our apparatus relative thereto, but it will be understood that in the formation of a complete package various conventional steps and operations are involved that are not illustrated in detail herein because they are Well known and constitute no part of our invention.

In the drawings, and particularly in Figs. 18 and 19, there is illustrated a conventional intermittently rotatable turret or rotor 40 carried by a shaft 4| mounted in a usual frame. The turret is provided with a disk shaped section 42 on which are mounted a series of our improved, equidistantly spaced brackets 10, such as shown in Fig. 1, which provide seats for the flaring mouths of the hollow formers or supports 6, which are of substantially the same shape and cross section as the package to be formed. These formers 9 may be made of thin sheet metal and are preferably twelve in number.

The turret it) is turned intermittently in the usual manner to bring the respective formers 9 step by step into cooperative relation to various mechanisms at or between a series of stops or stations corresponding in position to the numerals on the dial of a clock when the turret is viewed from the front, and for convenience these stations may be designated by the I to XII oclock positions to which they correspond.

The proper timing of the step by step or intermittent movement of the turret 46 may be accomplis'hed by any suitable indexing device (not shown), forming no part of our invention. The indexing device may be operated by power applied in the usual manner from a drive shaft 43 (Fig. 29) connected by beveled gears with a main shaft 44 which has fixed thereto a spur gear 45 meshing with a gear 46 on the shaft 47. The shaft 41 has fixed thereto a gear 48 meshing with a gear 49 on the shaft 59. A beveled gear 5i on the shaft 50 meshes with a beveled gear 52 on the shaft 53 connected with the indexing mechanism (not shown) for rotating the turret.

Sheet material, such as paper, tinfoil or laminated paper and tinfoil T is fed from a supply roll (not shown) over the roller '54 (Fig. 19-) and between the guide rollers 55 and 56. The roller 54 is loosely journalled on a shaft 57 journalled in a bracket of the packer frame in the usual manner. The shaft '57 has fixed thereto a pair of sprocket wheels, one of which is driven, through the chain 5.6 and suitable intermediate mechanism, from the chain 58 (Figs. 19, 20) meshing with a sprocket '58 on the drive shaft 43. The other sprocket wheel is connected through a sprocket chain '60 with a sprocket wheel '6! fixed on the shaft of the feedroller 55 in the usual manner.

The rollers 55 and 5B are mounted in a pair of frames 62 vertically oscillatable about theeaxis of the shaft '57 as a. center. The oscillation of the frames 62 and the rotation of the rollers 55, '56 and 5-4 feeds the strip 'I step by step past the triple bladed cutter mechanism 5 (Figs. 17 and 23')', which, in accordance with our invention, is mounted on the bracket 53 (Fig. 19) in place of the usual single bladed cutter mechanism of conventional packers. This triple bladed cutter mechanism is operable in timed relation to the feed of the'wrapper strip Tend to the rotation of the turret so by the actuating mechanism customarily used to operate the conventional single bladed cutter mechanism.

In accordance with our invention, a tape layer 64 (Figs. .18, 23) is ount d in a ignment with station on the housing .gn t which 9'. normally overlies the rearwardly extending portion of the turret 49.

vThe tape feeder 64 (Figs. 23, 24, 25) preferably comprises a folder 65; a pair of peripherally contacting feed rollers 66 and 61 for intermittently advancing the pull tape l; and a cutter 68 for cutting from the tape I 5 a length sufficient for a pull l5 after delivery to a support or former 9 at position XII.

The folder 65 consists of a plate containing a narrow slot 65' through which the tape 15 is led to crease it longitudinally and impart thereto a tendency to assume a channel shape or V-cross section imparting greater longitudinal rigidity to the tape.

The feed wheel 66 is fixed to a shaft 95a which is journalled in the frame 69 and has a bevel gear 10 and a gear H fixed to the ends thereof. The feed wheel 61 is fixed on a shaft 12 provided with a knurled knob 14 and a gear wheel 15; this shaft being journalled in a slide 16 which is vertically movable on slideways H of the frame 69. The slide 16 is normally biased downwardly by springs 18 and a follower 19 which is adjustable by a screw having a knurled knob 80 to regulate the traction between the peripheries of the feed wheels 66 and 61.

The gears H and 15 mesh with one another to effect their simultaneous rotation, and may be manually positioned by the knurled knob M to regulate their initial position relative to the tape 15 when the knurled knob 89 has been unscrewed to diminish the traction between the wheels 66 and 61. The length of the tape fed per revolution of the wheels 66 and 61 may be varied by the use of feed wheels of different diameters.

The feed wheels 65 and 61 are mechanically driven through the beveled gear 10 by means of a beveled gear 8| fixed on a shaft 82 (Figs. 23, 24) journalled in bearings 83 of a frame bracket. The shaft 82 has fixed thereon a spur gear 84 meshing with a gear 85 fixed on the shaft 86. The shaft 86 is rotated step by step in timed relation with the wrapper feeder and turret 49 through any suitable step by step mechanism, such as a Geneva movement or mutilated gear (not shown) so as to rotate the feed wheels 66 and 6'! in desired timed relation to the movements of the turret 49, so that a tape strip I5 is laid on each former 9 in position XII during or immediately following the ejection of a filled package from the former and before the folding of a new wrapper I on the former.

The Geneva movement, mutilated gear or other suitable step by step mechanism may be driven through any suitable means, such as gearing 81, 88, from a source of continuous rotary power, such as the shaft 51 actuated from the, main shaft 43. i

As soon as a suitable section of the tape l5 has been laid upon the former 9, the cutter 68 is rocked by power applied through the link 69' from any suitable source, such for instance as the link 91 hereinafter described.

In conventional cigarette packaging machines there may be provided a transfer plunger carried by the turret in complementary relation to each former 9, or a series of plungers may be mounted on the turret housing and reciprocated in the various formers 9 as they are moved into align- :ment with the several plungers. Our improve- :ments are adapted for use without change with either plunger arrangement, and, as an example only, we have illustrated our improvements in conjunction with the former typ of plunger ar rangement wherein each plunger is reciprocable in a complementary former 9 to a limited degree during a major portion of the turrets rotation by a cam mounted on the turret housing and is reciprocable to a greater degree at position XII by a supplementary plunger carried by the housing and reciprocable by an oscillating lever hav ing a timed relation to the turrets rotation.

In accordance with our invention (Figs. 18, 19, 23), there is substituted for each usual transfer plunger complementary to a former 9, a pusher or head 99 having a cam operated shaft 9| offset from the center thereof so as to lie below the feeder 95 so that the modified plunger 9il9l may be reciprocated by the usual cam and lever mechanisms without interference by or with the tape feeder 64.

As above noted, the rim or bracket ill of each former 9 is provided with a groove or channel 12 for positioning the pull it cut from the tape, with a step is for bending the pull at right angles when a Wrapper i is folded on the former 9, and with an aperture i i adjacent to the step 13 for the insertion of an adhesive applicator, To assist the walls of the groove 12 in positioning the pull 15', a spring guard 92 may be mounted on the packer frame in position for engagement by the upper surface of the rim l 9 during the initial movement thereof from XII oclock position toward I oclock position (Figs. 19, 23)

The wrapper i cut from the strip '1 by the cutter 8, and provided with edge slots 2 and 3, as previously described, is held against the leading face or front side of a former 9 at XII position in the usual manner and is wrapped circumferentially about such former by the usual wrapping means as the former moves from station XII to station I.

In accordance with our invention, this wrap ping of. the wrapper l around the former 9 (Figs. 21 and 22) bends the pull strip l5 against the step l3 and at right angles to the face 9a of the former, thereby clearing the channel I2 and uncovering the aperture Hi.

When the extremity I50, of the pull has been thus bent at right angles, the adhesive tipped applicator [I may be brought into action at any suitable location, as for instance at the station I. The applicator rod I! may be mounted in a housing 93 (Fig. 27) and yieldingly spring biased by an adjustable spring 94 therein. The housing 93 is mounted in an arm 95 which is pivoted on bearings 96 (Fig. 18) in the frame of the packer and biased by a spring 95'. The arm 95 is oscillated, through a pivoted flexible link 91, by a cam 98 fixed on the main shaft 44 (Figs. 18, 19, 20, 26 and 27) The lever 95 hasa cam nose 99 (Figs. 19, 26) for engaging an arm I of a bell crank fulcrumed on a bearing IOI {the bell crank including an arm I92, in which is journalled a wheel I93 having a beveled edge. The bearing Illl is supported by a bracket 104 of an adhesive fountain I05, and the bell crank arm [02 is biased aganist the action of the cam 98 by a spring I06 anchored on the bracket I04.

The fountain 15 contains a beveled edge wheel E91 which rotates in and projects above an adhesive pool in the fountain. If desired, the wheel 19! may be continuously rotated by a motor I98.

The, cam 98 is so shaped that during the portion of the rotation of the shaft 44, which effects a step movement of the turret 40, the spring is permitted to bias downward the rear end of the lever 95 and elevate the forward end of this lever so as to lift the applicator stem I! out of 1 l the path of any moving former 9. In this position, the bell crank Hill-Hi2 is turned on its axis It)! so as to bring the beveled edge of the adhesively coated wheel I03 into contact with the end of the applicator stem i7 and coat it with adhesive.

When a former 9, with a wrapper I folded thereon, comes to rest at the station I, the cam 98 elevates the link 91 to rock the lever 95 so as to move the stem I'l downwardly to deposit a spot of adhesive on the outer face of the wrapper section adjacent to the upturned pull section Isa. The downward movement of the nose 99 of the lever 95 permits the spring I96 to retract the wheel I from the path of the stem I? and bring the periphery of the Wheel I03 into contact with the adhesively coated periphery of the rotating wheel I07.

During the progress of a former 9 from station I to station V, the wrapper I thereon is tucked and folded and sheathed in a label jacket in the usual manner. By the time the former 9 arrives at station VII, the wrapping, tucking and folding of the inner wrapper or shell and of the jacket have been completed, and consequently the pull extension I511 may now be further bent so as to overlie the edge of the label jacket and be secured in position by the adhesive spot previously applied to the shell by the applicator IT.

This bending or folding of the pull extension its at the station VI may be effected by mounting the folding finger It on the end of a bent lever I09 fulcrumed on a frame bearing I I and connected through an adjustable, yielding link I I I with an arm I I 2 fixed to the conventional oscillating lever 3% for reciprocating the supplementary plunger for operating each transfer plunger 98 at station XII above referred to, via, the part 340 of Patent No. 1,926,192. The arm H2 is fixed to the lever 348 adjacent to the axis of oscillation thereof. The link I I I comprises telescoped members having limited longitudinal movement relative to one another and normally biased to their outward positions by a coiled spring. Hence when the lever t ill is rocked to the full line position shown in Fig. 28 to advance a plunger 90 at station XII to the position shown in Fig. 23, it rocks the member I I 2 and thrust is transmitted through the spring of the link I I I to the lever I99 to move the folder I 9 yieldingly against and fold a pull extension Ida of a pouch on a former 9 at station VI. During transit of a pouch from station I to station VI the adhesive applied by the applicator I1 becomes more tacky so that when the pull extension IEa is folded at station VI, it immediately adheres to l the adhesive spot on the shell.

In passing from station VI toward station IX, the pouch is subjected to the action of a heater (not shown) to dry the adhesive sealing its seams and ends and attaching the end I5a of the pull to the shell.

Upon the arrival of each former 9 at station IX, there is brought into registration therewith one of a series of pockets II5 (Figs. 18, 19, 31) each containing a compacted bundle of cigarettes 3| arranged in three rows, preferably containing respectively 7-6-7 cigarettes. The pockets I I5 are carried on the arms of a conventional rotary compacting mechanism 1.15.

When a pocket I I5 is brought into registration with the mouth of a. former 9, the transfer plunger 90 complementary to the latter is operated in the usual manner by cam on the turret housing (not shown) to push the bundle of cigarettes 3! out of the compactor pocket II5 into the former 9 so 12 that the outer ends of the cigarettes are flush with the edge of the mouth of the former 9 and rim I0 (see Figs. 18, 19 and 31).. The plunger 50 is then retracted by the cam (not shown) to permit relative movements of the turret 49 and compactor I I6.

After the bundle of cigarettes 3| has been inserted in a pouch, an adhesive applicator 33 is inserted in the aperture I4 through the rim I9 and former 9 to apply a spot of adhesive 32 to an end cigarette of the middle row of the bundle. Preferably the insertion in the applicator takes place when the former 9 stops at station XI.

The applicator 33, and the mounting and operation thereof, are similar to the applicator I1 and the mounting and operation thereof, that is to say, the headed stem 33 (Fig. 29) is reciprocably mounted in a housing 93a and yieldingly spring biased by an adjustable spring 94a therein. The housing 93a is mounted in an arm 95a, which is pivoted on bearings 98a in the frame of the packer and biased by a spring 95a mounted on the packer frame. The arm 95a is rocked through a pivoted, flexible, link 97a by a cam 98a fixed to the main shaft 44 (Figs. 19, 20 and 29). The lever 95a has a cam nose 99a for engaging the arm Ififla of a bell crank lever fulcrumed on the bearing I9Ia and having an arm 32a in which is journalled a wheel I93a having a beveled edge. The bearing I0 Ia is supported by a bracket Iii ia of an adhesive fountain I95a, and the bell crank arm I920 is biased by a spring Nita anchored on the bracket Iii ia. The fountain Itfia contains a beveled wheel IIl'Ia which rotates in and projects above an adhesive pool in the fountain. If desired, the wheel lils'a may be continuously rotated by a motor similar to the motor I98.

The cam 98a is so shaped that during the portion of the rotation of the shaft it which effects a step movement of the turret, the spring 9551 is permitted to bias downward the rear end of the lever 95a (Fig. 29), thereby elevating the forward end of the lever 95a so as to lift the applicator stem 33 out of the path of any moving former 9; In this position of the lever 95a (Fig. 19) the bell crank Iflfia, I 02a is turned on its axis I 9 la so as to bring the beveled edge of the adhesively coated wheel Iota into contact with the end of the applicator stem 33 and coat it with adhesive. When a former 9 containing a bundle of cigarettes SI comes to rest at, for instance, the station XI, the cam 98a acts through the link 9M to rock the rear end of the lever 95a upward so as to move the spring biased stem 33 downwardly through the aperture It in the rim Ill and former 9 to deposit a spot of adhesive 32 on the end cigarette SIc' of the middle row 3Ic of the bundle (Figs 9, 10, 29).

The aperture I4 is preferably positioned at a distance of about 1 inches from the mouth of the former 9 so that the spot of adhesive 32 is applied to the middle half of the length of the cigarette.

The downward movement of the nose 99a of the lever 95a, toward the position shown in full lines in Fig. 29, permits the spring Itfia to retract the wheel IB3a from the path of the stem 33 and bring the periphery of the wheel into contact with the adhesively coated periphery of the wheel H110. to renew the supply of adhesive on the wheel I93a. When the pin 33 is again rocked away from the former 9, to the-dotted line position shown in Fig. 29, the nose 99a of the lever 95;: engages and rocks the bell crank arm mam 13 so as to move the periphery of the wheel l03a into engagement with the end of the stem 33 and renew the supply of adhesive thereon.

When a filled former 9 has been moved from position XI to position XII, its plunger 90 is given an extreme forward movement through the lever 340 to complete the insertion of the bundled cigarettes into the former and against the bottom of the pouch and to eject the cigarettes and pouch from the former 9, as shown in Fig. 23. This movement transfers the filled pouch into the entrance of the delivery guideway I20 and into position for the usual tucking and folding of its sections la, lb, Ia and Id. The stripped former 9 is thus prepared for the laying of a new pull strip 15' and the positioning and cutting of 'a new wrapper I for a new cycle of operations.

The ejected package in the guideway I2!) is moved along the guideway by the pressure of a follower [21. Such lateral pressure on the face of the packages tends to bulge upward the narrow upper side of the package. To reverse this outward bulging of the upper side of the package and to press the pull l running along the inner face of such side against the adhesive spot 32 applied by the applicator 33, we mount a series of fingers 36 on a plate I23 which is connected, through pivoted links I24 and I25 and spring l26, with anoscillating arm 62 of the paper feed mechanism. Consequently each paper feeding movement of the arm 62 imparts a yielding pressure to a group of the finished packages on the guideway I20 without interfering with the movement of the packages to provide room for the ejection of a new package. Such repeated yielding pressures insures the adhesion of the pull l5 to the spot 32 whose tackiness increases during its transit from the applicator 33 to the fingers 36.

From the foregoing it will be understood that during or immediately upon the completion of the ejection of a filled pouch from a given former 9 at position XII (Fig. 23), the shaft 82 is.

rotated to impart rotation to the feed wheels 66 and 61 which feed a predetermined length of laminated tape, which has been creased by the folder 95', through the slot l2 and onto the top 9a of the former 9, which has just been emptied.

As soon as a length of tape sufficient to form a pull [5 has been laid, it is severed by the operation of the cutter 68 by the cam 98 and intermediate linkage. Substantially simultaneously with the laying of the tape, the arms 52 and the rollers 55 and 56 advance a strip of sheet material T from which a new wrapper I is severed and slit by the knives 6, I and 8 while in position for engagement by the leading face of the former 9. The wrapper is bent around the former 9 and over the pull (Fig. 21) upon the movement of the turret 40 in a clockwise direction when looked at from the front (anti-clockwise as it appears in Figs. 19 and 31). The bending of the wrapper I over the pull l5 bends the end l5a of the latter at right angles thereto against the step l3 (Fig. 22) and, while the pull end 15a is so bent, a spot of adhesive is applied by the applicator I1 and on a part la of the wrapper which will subsequently form an end tuck of the package; the spot being near the base of the pull end l5a. After the bottom of the wrapepr has been tucked and folded and '14 the wrapper has been sheathed in a pouch in the usual manner during the progress of the former from station XII to station VI, the projecting end of the pull l5a. is bent back (Figs. 28, 32) against the adhesive spot applied by the applicator I1.

Thereafter a bundle of cigarettes, preferably arranged inrows of 1-6-1 are inserted in the former and part-way within the length of the pouch formed by the wrapper l and label It and a further spot of adhesive 32 is applied by the applicator 33 to a cigarette aligned with the pull 15' at a pointon the cigarette just beyond the outer edge of the wrapper.

The bundled cigarettes are then pushed completely into the pouch (Figs. 23, 34) and the open end of the wrapper l is tucked and folded (Figs. 33 and 34) so that the extremity [5a of the pull projects laterally from the completed package. An intermediate section of the pull strip forms a loop (Fig. 14) around the end tuck la and the inner section of the pull strip is adhesively connected to an end cigarette of the middle row, which cigarette is spaced from the package wall and slides freely in grooves formed by adjacent cigarettes of the two outer rows 3m and 31b. The end tuck la and the outer section of the pull loop thereon are partly covered by the severed end sections to and I01 of said flaps bent down from the front and back walls of the wrapper I and such flaps are secured in folded position by a stamp 31 or the like; the stamp being pasted to the front and back walls and main portions of the flaps lo and Id and projecting slightly over the edges of the severed portions l0 and Id of the flaps.

When the projecting end l5a ofthe pull strip is pulled laterally, it raises the tuck Ia to which it is adhesively connected and thereby draws the severed fold sections lo and Id, from beneath the edge of the stamp 31 and turns them upwardly. A continued lateral pull on the pull splits it from its adhesive connection'to the outer face of the tuck la, and thereupon imparts an endwise stress on the cigarette 31c, which is thereby drawn upward until the adhesive spot 32 rises above the top of the package. Whereupon the pull l5 splits or strips off the cigarette 3lc and leaves it partially projecting from the package but free from the pull strip.
