In addition, in the present embodiment, as shown in figure 3, keeping the feed speed of Filamentous elastomeric element 23 and speed of wrap permanent It is fixed, so that the Filamentous elastomeric element 23 in constant elongation multiplying power is alternatively arranged with constant in the conveying direction.But not It is limited to this, for example, it is also possible to which the interval of the conveying direction of Filamentous elastomeric element 23 or elongation multiplying power is made to be in cyclically-varying.

In addition, the initial Filamentous elastomeric element 23 being wrapped on conveyer belt 611~614 inclines relative to width direction Tiltedly.In Fig. 4, for the Filamentous elastomeric element 23 more upper than conveyer belt 611~614, the front side of width direction Filamentous elastomeric element it is leading, for the Filamentous elastomeric element 23 of downside, the inboard Filamentous elastomeric element of width direction In advance.Then, for the conveyer belt of top 611,613, make the rotational speed ratio of the conveyer belt 611 of width direction front side The rotational speed of the conveyer belt 613 of width direction inboard is slow, for the conveyer belt 612,614 of lower section, makes in width direction The rotational speed of the conveyer belt 614 of side is slower than the rotational speed of the conveyer belt 612 of width direction front side.As a result, to Filamentous bullet Property component 23 inclination be modified, when being engaged by a pair of first engagement roller 63a, 63b, to make Filamentous elastomeric element 23 along width direction.But it is not limited to this, can not also be modified to the inclination of Filamentous elastomeric element 23, in this case Apparatus structure can be simplified.

First engagement roller 63a of the top in a pair of first engagement roller 63a, 63b will from the top of Filamentous elastomeric element 23 It is conveyed while first 22a is on peripheral surface, the first engagement roller 63b of lower section is under Filamentous elastomeric element 23 It is conveyed while just by second 22b on peripheral surface.In addition, on second 22b such as by applying mechanism 65 Bonding agent a1~a3 is coated with shown in Fig. 2A.In addition, be not limited to apply bonding agent a1~a3 on second 22b, it can also be Bonding agent is applied on first 22a, can also all apply bonding agent in two on pieces.Moreover, the filiform extended in the width direction Elastomeric element 23 is put to successively by conveyer belt 611~614 by first 22a of a pair of first engagement roller 63a, 63b conveying Between second 22b.

Then, in the immediate position of each peripheral surface of a pair of first engagement roller 63a, 63b（Junction P1）, pressed from both sides in centre First 22a and second 22b equipped with the Filamentous elastomeric element 23 extended in the width direction, by the first engagement roller 63a of a pair, 63b is clamped and squeezes.As a result, first 22a and second 22b is engaged with Filamentous elastomeric element 23 and is integrally formed.Separately Outside, however it is not limited to be integrally formed, such as can also be integrally formed by welding using bonding agent.

In addition, make the interval of each peripheral surface of the first engagement roller 63a, 63b of a pair at the P1 of junction, than first 22a Thickness, Filamentous elastomeric element 23 thickness and second 22b thickness aggregate thickness it is small.By constituting as described above, It can be clamped and squeezed with a pair of first engagement roller 63a, 63b（It can be compressed with through-thickness）Centre is folded with Filamentous elastic portion First 22a and second 22b of part 23, so as to so that first 22a and second 22b and Filamentous elastomeric element 23 are reliable Ground is integrally formed.

In addition, the peripheral surface of a pair of first engagement roller 63a, 63b is formed by silicon rubber.In this way, by with bullets such as silicon rubber Property component form the peripheral surface of a pair of first engagement roller 63a, 63b, so as to make in junction P1, each roller 63a, 63b outer Circumferential surface compressive deformation improves close property, can make first 22a and second 22b and Filamentous elastomeric element 23 more reliably structure Integrally.

Moreover, after first 22a and second 22b is engaged with Filamentous elastomeric element 23, be wrapped in conveyer belt 611~ Filamentous elastomeric element 23 on 614 is cut off using two outsides of cutting section 64 in the width direction, is stretched for the first time to manufacture Contracting piece 30.In this way, by manufacturing along the flexible first time telescopic sheet 30 in the direction intersected with conveying direction, for example, working as Installation is made by first time telescopic sheet 30 on the body part 10 of the disposable diaper 1 manufactured as conveying direction using length direction At flank 20a, 20b when, either one need not be made to be rotated by 90 °, manufacturing process can be simplified.

＜ steps 2：The manufacture ＞ of second of telescopic sheet 31

As shown in figure 5, the device portion of second of telescopic sheet 31 of manufacture has：First engagement roller 63a, 63b of a pair, major diameter Roller 70, path roller 71 and rotating knife 72（Implement the mechanism of cutoff process）.It is connect by the first engagement roller 63a, 63b of a pair First time telescopic sheet 30 obtained from conjunction, is hereafter handed off to major diameter roller 70, and path roller 71 is handed off to from major diameter roller 70.It connects It, as shown in Figure 2 B, on the peripheral surface of path roller 71, the both ends of the width direction of first time telescopic sheet 30 are cut off, To second of telescopic sheet 31 of manufacture.

As shown in Fig. 2, since flank 20a, 20b use two first time telescopic sheets 30, manufacture is flexible for the first time Property piece 30 device portion 74,75 major diameter roller 70 following above and setting there are two.In addition, the device portion 74 of lower section and top Device portion 75 configure with being staggered in the direction of the width so that two first time telescopic sheets 30 interval in the direction of the width Ground is on the peripheral surface of major diameter roller 70.Major diameter roller 70 and path roller 71 are in the same manner as the first engagement roller 63a, 63b, with first The width direction of secondary telescopic sheet 30 be it is axial rotated, and first time telescopic sheet 30 carried out on peripheral surface defeated It send.

Rotating knife 72 is arranged in the lower section of path roller 71, is axial revolved with the width direction of first time telescopic sheet 30 The both ends of the width direction of first time telescopic sheet 30 are cut off while turning.As rotating knife 72, for example, enumerating disc parts Outer peripheral edge complete cycle become point of a knife rotating knife.In order to which the both ends of the width direction of two first time telescopic sheets 30 are cut It is disconnected, as shown in Figure 6A, correspondingly with the off-position C1 of the transported first time telescopic sheet 30 on path roller 71, four rotations Rotor 72 is arranged in the width direction.

In this, it is assumed that not keeping the elongation state of the width direction of first time telescopic sheet 30 and making first time telescopic sheet 30 free shrinks, and the both ends of the width direction of first time telescopic sheet 30 are cut off.Make first time telescopic sheet 30 certainly When by shrinking, fold is generated on first time telescopic sheet 30 along conveying direction or width direction（It is concave-convex）.Then, cause by revolving Cuttability when rotor 72 is cut off deteriorates.In addition, when making first time 30 free shrink of telescopic sheet, for example, it is possible to The power acted on when by the error for the elongation multiplying power for being folded in intermediate Filamentous elastomeric element 23, contraction is influenced, and The position of the width direction of the first time telescopic sheet 30 on transport path is caused to be staggered.So as to cause cannot be in cut-out appropriate Position C1 cuts off first time telescopic sheet 30, along the cutting line complications of conveying direction aesthetics should be deteriorated.

In other words, in order to cut off first time telescopic sheet 30 in off-position C1 appropriate, for example, it is desired to utilize camera Or sensor etc. is managed the position of the width direction of first time telescopic sheet 30, is complicated so as to cause apparatus structure. In addition, if first time telescopic sheet 30 is temporarily shunk during from by manufacture until being cut off, setting is needed to use In the mechanism for making first time telescopic sheet 30 extend in the width direction again, complicated so as to cause apparatus structure.

Then, in the present embodiment, during from manufacturing first time telescopic sheet 30 until cut-out, keep The elongation state of the width direction of first time telescopic sheet 30.Therefore, in first 22a and second 22b（It is equivalent to a pair Serialgram）Between be folded with the state of the Filamentous elastomeric element 23 extended in the width direction, make first 22a and second 22b Pass through a pair of first engagement roller 63a, 63b（It is equivalent to a pair of rolls）Between and they are engaged, and cut from conveyer belt 611~614 Fracture of wire shape elastomeric element 23, to form first time telescopic sheet 30（It is equivalent to the non-individual body of telescopic sheet）, either upper During stating or after this period, all keep first time telescopic sheet 30 wound in a pair of first engagement roller 63a, 63b A roller peripheral surface（Curved surface）On state.By constituting as described above, the width of first time telescopic sheet 30 can be kept Spend the elongation state in direction.

Moreover, until will be being handed off to than first time telescopic sheet 30 made of the device portion 74 more on the lower of major diameter roller 70 Until major diameter roller 70, i.e. between a pair of first engagement roller 63a, 63b（P1）Play the first engagement roller 63a of top（It is equivalent to One roller）With major diameter roller 70（It is equivalent to the first roller）Between（P2）Until, it keeps first time telescopic sheet 30 wound on upper The peripheral surface of first engagement roller 63a of side（Curved surface）Above its state extended in the width direction is made to be conveyed.Similarly, directly It is engaged until first time telescopic sheet 30 made of the device portion 75 top is handed off to major diameter roller 70, i.e. from a pair first Between roller 63a, 63b（P3）Play the first engagement roller 63b of lower section（It is equivalent to one roller）Between major diameter roller 70（P4）For Only, it keeps first time telescopic sheet 30 making it in the width direction on the peripheral surface of the first engagement roller 63b of lower section The state of elongation is conveyed.It, can be by first time telescopic sheet 30 so that it is stretched in the width direction by constituting as described above Long state is handed off to major diameter roller 70 from a pair of first engagement roller 63a, 63b.

In addition, until two first time telescopic sheets 30 are handed off to path roller 71 from major diameter roller 70, i.e. from first A roller in engagement roller 63a, 63b and between major diameter roller 70（P2、P4）It plays between major diameter roller 70 and path roller 71（P5）For Only, by two first time telescopic sheets 30 wound on the peripheral surface of major diameter roller 70（Curved surface）On state conveyed.Pass through It constitutes as described above, it can be by two first time telescopic sheets 30 so that its state extended in the width direction is handed over from major diameter roller 70 It is connected to path roller 71.

In turn, until reaching between path roller 71 and rotating knife 72, two first time telescopic sheets 30 are wound In the peripheral surface of path roller 71（Curved surface）On state conveyed.That is, keeping that major diameter roller 70 and path roller 71 will have been passed through（Phase When in the second roller）Between first time telescopic sheet 30 so that it is extended in the width direction on the peripheral surface of path roller 71 State conveyed, also, to first time telescopic sheet 30 implement cutoff process.

By constituting as described above, first time telescopic sheet 30 can be cut off in the state of not generating fold, can be pressed down Cuttability processed deteriorates.It is additionally possible to suppress dislocation, i.e. of first time telescopic sheet 30 in the direction of the width on transport path Dislocation of the telescopic sheet 30 relative to rotating knife 72 in the direction of the width can cut off first in off-position C1 appropriate The both ends of the width direction of secondary telescopic sheet 30.Accordingly it is also possible to which aesthetics is inhibited to deteriorate.In addition, it is not necessary that for the first time The position of the width direction of telescopic sheet 30 is managed, so as to simplify apparatus structure.In addition, from first time retractility During piece 30 has been manufactured until being cut off, the elongation state of the width direction of first time telescopic sheet 30 is kept, Therefore, there is no need to that the mechanism for making temporary contracted first time telescopic sheet 30 extend in the width direction again is arranged, from And apparatus structure can be simplified.

In addition, assuming that not being by roller but by flat face from rear support and to convey first time telescopic sheet 30 In the case of, in order to keep first time telescopic sheet 30 width direction elongation state, need such as using pressing belt from Surface side pins first time telescopic sheet 30.But as present embodiment by first time telescopic sheet 30 wound on work In the case of on the curved surface of the peripheral surface of roller, even if being not provided with the mechanisms such as pressing belt, first time telescopic sheet can also be kept The elongation state of 30 width direction.That is, by conveying first time telescopic sheet 30 on the peripheral surface of roller, it can To keep the elongation state of the width direction of first time telescopic sheet 30 by simple apparatus structure.

Moreover, so that each peripheral surface of a pair first engagement roller 63a, 63b, major diameter roller 70 and path roller 71 is become has holding The face of the characteristic of the elongation state of the width direction of first time telescopic sheet 30.That is, making the peripheral surface of each roller 63a, 63b, 70,71 As the face for inhibiting the clamping of peripheral surface sliding opposite with first time telescopic sheet 30 strong.Therefore, in the present embodiment, The surface of first engagement roller 63a, 63b of a pair, major diameter roller 70 and path roller 71 is formed by silicon rubber.In addition, both can be in metal Silicon rubber is wound on the surface of the roller of system, entire roller can also be formed by silicon rubber.By constituting as described above, from for the first time During telescopic sheet 30 has been manufactured until being cut off, the width of first time telescopic sheet 30 can be more reliably kept The elongation state in direction.

In addition, being not limited to form the peripheral surface of roller by silicon rubber, as long as being configured to form the peripheral surface of roller by elastomeric element So that the peripheral surface of roller has elasticity.For example, it is also possible to usual using natural rubber, polyurethane rubber, butyl rubber etc. It is used as the raw material of rubber to form the peripheral surface of roller.It is concave-convex alternatively, it is also possible to be formed on the peripheral surface of roller.For example, both may be used Implement fine surface roughness with the peripheral surface of two pairs of rollers（It is concave-convex）Polishing processing, can also the jet grinding as sand paper Needle can also be arranged in sand.Come the peripheral surface progress surface of two pairs of rollers alternatively, it is also possible to peripheral surface implementation plasma spraying etc. of two pairs of rollers Modification, so as to keep telescopic sheet width direction elongation state.Roller can be improved as long as face with the above characteristics Peripheral surface clamping, so as to more reliably keep first time telescopic sheet 30 width direction elongation state.Separately Outside, the peripheral surface for being combined with above-mentioned characteristic can also be formed.In addition, can both make the peripheral surface phase of each roller 63a, 63b, 70,71 Together, its difference can also be made.Alternatively, it is also possible to use the roller for not having above-mentioned characteristic.

In addition, passing through a roller in a pair of first engagement roller 63a, 63b in first time telescopic sheet 30（Leading portion roller）With Major diameter roller 70（Back segment roller）Between when, and pass through major diameter roller 70 in first time telescopic sheet 30（Leading portion roller）With path roller 71 （Back segment roller）Between when, first time telescopic sheet 30 is clamped and squeezes, so that through-thickness compresses it.Therefore, make leading portion The interval of each peripheral surface of roller and back segment roller immediate place P2, P4, P5 are smaller than the thickness of first time telescopic sheet 30.Pass through It constitutes as described above, when joining first time telescopic sheet 30 to back segment roller from leading portion roller, also can more reliably keep first The elongation state of the width direction of secondary telescopic sheet 30.

In addition, by forming a pair first engagement roller 63a, 63b, major diameter roller 70 and path roller by elastomeric elements such as silicon rubber 71 each peripheral surface can improve the mutual close property of peripheral surface of roller when being clamped and squeezing first time telescopic sheet 30.Cause This also can more reliably keep first time telescopic sheet when joining first time telescopic sheet 30 to back segment roller from leading portion roller The elongation state of 30 width direction.

In addition, as shown in Figure 6A, on the peripheral surface of path roller 71, being provided with for the point of a knife for rotating knife 72 in complete cycle The groove portion 711 of entrance.Moreover, as shown in Figure 6B, rotating knife 72 is not to have carrier（Undertaking cutter）State, do not make rotation The point of a knife of knife 72 contiguously cuts off first time telescopic sheet 30 with path roller 71.In addition, due to being provided with relative to path roller 71 Four rotating knifes 72, therefore, correspondingly there are four groove portions 711 for setting on path roller 71 with the installation position of each rotating knife 72. Moreover, the depth of the point of a knife of rotating knife 72 of the depth of groove portion 711 than entering groove portion 711 is deep, in case the point of a knife of rotating knife 72 connects Touch the bottom of groove portion 711.

In this case, if being not outer layback of the boundary by first time telescopic sheet 30 to width direction with rotating knife 72 Stretch, then by the first time telescopic sheet 30 that rotating knife 72 is pressed into groove portion 711 be possible to make a concession to groove portion 711 it is inboard without It can cut-out.But in the present embodiment, state of the first time telescopic sheet 30 to be wound onto on the peripheral surface of path roller 71 It is cut off.Therefore, the elongation state of the width direction of first time telescopic sheet 30 is kept to be cut off, wanting with rotating knife 72 will First time telescopic sheet 30 is pressed into the bottom side of groove portion 711（It is the upside of upper and lower directions in fig. 6b）And cut off power on the contrary, with Rotating knife 72 is that boundary acts on first time telescopic sheet 30 to the power of the outer side stretching of width direction.As a result, rotation Rotor 72 can cut off first time telescopic sheet 30.

In this way, in cut-out place, in a manner of between the point of a knife of rotating knife 72 and the bottom of groove portion 711 there are space, Cut-out first time telescopic sheet 30 and by the point of a knife of rotating knife 72 and the bottom clamping of groove portion 711 and do not squeeze flexible for the first time Property piece 30.By constituting as described above, the abrasion of the point of a knife of rotating knife 72 can be inhibited, so as to realize the height of rotating knife 72 Service life.In addition, in the present embodiment, since first time telescopic sheet 30 being carried out on the peripheral surface of path roller 71 Therefore cut-out can be not provided with pressing belt etc. and keep the width of first time telescopic sheet 30 by simple apparatus structure The elongation state in direction is simultaneously cut off.

In addition, rotating knife 72 is configured in above-below direction relative to path roller 71（Vertical direction）Lower section, from for the first time The lower section of telescopic sheet 30 makes rotating knife 72 contact.By constituting as described above, generated when being cut off by rotating knife 72 Chip（Crushing piece）It falls below to the side opposite with first time telescopic sheet 30, is stretched for the first time so as to prevent from falling on On contracting piece 30.It is thus possible to improve the quality of flank 20a, 20b using first time telescopic sheet 30.In addition, it is not necessary that thinking Side tries to prevent chip from falling on first time telescopic sheet 30, so as to simplify apparatus structure.

In addition, in the cut-out place for cutting off first time telescopic sheet 30 by rotating knife 72, path roller 71 is made to be stretched along for the first time The direction that contracting piece 30 is advanced to the downstream side of conveying direction rotates, and in contrast, makes rotating knife 72 along first time telescopic sheet The opposite direction of 30 conveying direction rotates.By constituting as described above, rotating knife 72 can be to wanting under conveying direction Trip skidding into first time telescopic sheet 30 apply tension round about, so as to improve cutting for first time telescopic sheet 30 Disconnected property.

In addition, making the peripheral speed of rotating knife 72（M/ points）Than the conveying for conveying first time telescopic sheet 30 by path roller 71 Speed（M/ points）Soon.By constituting as described above, the rotation contacted per unit time with first time telescopic sheet 30 can be increased The length of the point of a knife of knife 72, so as to improve cuttability.

In addition, as shown in Figure 2 A, in the inner surface for second 22b for constituting first time telescopic sheet 30（Joint surface）On Coated with bonding agent a1~a3.Specifically, the both ends of the width direction of second 22b, more lean on than off-position C1 Two positions at the position in the outside of width direction are coated with first bonding agents a1, and width direction is more being leaned on than off-position C1 Inside position two positions be coated with second bonding agents a2, the second bonding agents in the left and right for being applied to width direction Between a2, many third bonding agent a3 are coated with across defined interval.In addition, each bonding agent a1~a3 is along second 22a's Conveying direction extends.The length longest of the width direction of second bonding agents a2（The coating amount of per unit area is more）, third bonding The length of the width direction of agent a3 is most short（The coating amount of per unit area is few）.

Moreover, by making being not coated in rotating knife 72 and first time telescopic sheet 30 be covered with position, i.e. first of bonding agent Location contacts between bonding agent a1 and second bonding agents a2, come cut off first time telescopic sheet 30 width direction both ends Portion.By constituting as described above, can prevent from adhering to bonding agent on rotating knife 72, and can prevent due to the attachment of bonding agent Cuttability is caused to deteriorate.In addition, it is not necessary that bonding agent is got rid of from rotating knife 72 by every means, so as to simplify device knot Structure reduces maintenance times.

In addition, before being cut off by rotating knife 72, the Filamentous elastomeric element between first bonding agents a1 and second bonding agents a2 23 elongations, therefore, when cutting off Filamentous elastomeric element 23 between first bonding agents a1 and second bonding agents a2, cut-off silk The end of shape elastomeric element 23 is contracted to the coating position of bonding agent a1, a2.Therefore, as shown in Figure 2 B, Filamentous elastomeric element 23 The both ends of width direction be contracted to the coating position of second bonding agents a2, Filamentous elastomeric element 23 can be accommodated in second The both ends of the width direction of secondary telescopic sheet 31（Cutting portion）Inside.In other words, by to be cut by rotating knife 72 Disconnected off-position C1 is position coating bonding agent a1, a2 of the both sides of the width direction of boundary, can be by Filamentous elastomeric element 23 are accommodated in second of telescopic sheet 31.It is thus possible to improve the aesthetics of second of telescopic sheet 31, can prevent by from The Filamentous elastomeric element 23 that piece stretches out generates unfavorable condition（Such as the component hung in the device is first-class）.

In addition, it is the position as edge 31 ' that the position of the end side of width direction is more leaned on than off-position C1, but As long as applying first bonding agents a1.By constituting as described above, the chip of Filamentous elastomeric element 23 after cut-out can be prevented It disperses between first 22a and second 22b.Therefore, it is easy recycling edge 31 ', furthermore, it is possible to prevent Filamentous elasticity The chip of component 23 is involved in component or product in device.

In addition, in the present embodiment, cutting off first time telescopic sheet 30 by rotating knife 72, but it is not limited to this.For example, It can also be cut off by fixing cutter, the ultrasound that the while of making point of a knife vibrate by ultrasonic activation can also be used to be cut off Wave cutter are cut off, and can also be blown by laser.Alternatively, it is also possible to be clamped and squeeze by rotating knife 72 and path roller 71 First time telescopic sheet 30 and cut off, position of the first time telescopic sheet 30 coated with bonding agent can also be cut off, Bonding agent can also be not provided with as the position of edge 31 '（First bonding agents a1）.Alternatively, it is also possible to be stretched for the first time The off-position of contracting piece 30 keeps the direction of travel of rotating knife 72 identical as the direction of travel of path roller 71, and, however it is not limited to Rotating knife 72 is set in the lower section of path roller 71, can also be arranged in other positions.

＜ steps 3：The manufacture ＞ of third time telescopic sheet 32

As shown in figure 5, the device portion of manufacture third time telescopic sheet 32（The mechanism of other pieces is engaged on telescopic sheet） With path roller 71 and the second engagement roller 73.Second engagement roller 73 compared to rotating knife 72 conveying direction downstream side setting with The opposite position of path roller 71, with width direction be it is axial rotated, by the first lower plate 25a, the second lower plate 25b and the Three lower plate 25c are conveyed on peripheral surface.In addition, first~third lower plate 25a~25c with and in path roller 71 The bonding station of upper transported two second of telescopic sheets 31 engagement is matchingly with interval in the direction of the width State is wound onto in the second engagement roller 73.In addition, as shown in Figure 2 C, in the right-hand end of the width direction of the first lower plate 25a Portion, the second lower plate 25b width direction both ends and third lower plate 25c width direction left end, coating There is bonding agent a4.But it is not limited to this, can also apply bonding agent on second of telescopic sheet 31, can also be in two on pieces All apply bonding agent.

Moreover, in the immediate position of each peripheral surface of path roller 71 and the second engagement roller 73（Junction P6）, two Secondary telescopic sheet 31 and first~third lower plate 25a~25c are clamped and are squeezed by path roller 71 and the second engagement roller 73.Its As a result, as shown in Figure 2 C, two second of telescopic sheets 31 and first~third lower plate 25a~25c are engaged and are constituted one Body, to manufacture third time telescopic sheet 32.

In this, it is assumed that not keeping the elongation state of the width direction of second of telescopic sheet 31 and making second of telescopic sheet 31 free shrinks, and first~third lower plate 25a~25c is engaged on second of telescopic sheet 31.Make to stretch for second Property 31 free shrink of piece when, generate fold in second of 31 upper edge conveying direction of telescopic sheet or width direction.Therefore, second The bonding area that telescopic sheet 31 is engaged with first~third lower plate 25a~25c（Contact area）Reduce, leads to bond strength Weaken.In addition, when making second of 31 free shrink of telescopic sheet, for example, it is possible to by intermediate Filamentous bullet is folded in Property the error of elongation multiplying power of component 23, the influence of power that is acted on when shrinking, and lead to stretching for the second time on transport path The position of the width direction of contracting piece 31 is staggered.So as to cause cannot be in the engagement position appropriate of second of telescopic sheet 31 One~third lower plate 25a~25c, should be tortuous along the closing line of conveying direction.Moreover, also aesthetics is caused to be deteriorated.

Then, in the present embodiment, keep that second of retractility between path roller 71 and rotating knife 72 will have been passed through Piece 31（It is equivalent to the non-individual body of telescopic sheet）The shape for making it extend in the width direction on the peripheral surface of path roller 71 State is conveyed, also, is implemented first~third lower plate 25a~25c（It is equivalent to other serialgrams）It is flexible with second Property piece 31 engage processing.

By constituting as described above, first can be engaged on second of the telescopic sheet 31 for not generating this state of fold ~third lower plate 25a~25c can inhibit to cause bond strength to reduce along with the reduction of bonding area.Furthermore it is possible to Inhibit the dislocation of second of telescopic sheet 31 in the direction of the width on path roller 71, and can be in second telescopic sheet 31 First~third of engagement position lower plate 25a~25c appropriate.Alternatively, it is also possible to inhibit aesthetics to deteriorate.Further, since not The position of the width direction to second of telescopic sheet 31 is needed to be managed, also, it is not necessary to which being arranged makes second of retractility Therefore the mechanism that piece 31 extends in the width direction again can simplify apparatus structure.Even if in addition, being not provided with the machines such as pressing belt Structure can also keep second by winding the simple apparatus structure of second of telescopic sheet 31 in the peripheral surface of path roller 71 The elongation state of the width direction of secondary telescopic sheet 31.

In addition, forming the surface etc. of path roller 71 by silicon rubber, kept to make the peripheral surface of path roller 71 become to have The face of this characteristic of elongation state of the width direction of second of telescopic sheet 31.Therefore, from second of 31 quilt of telescopic sheet During having manufactured until being cut off, the elongation state of the width direction of second of telescopic sheet 31 is more reliably kept. In addition, making the interval of each peripheral surface of the path roller 71 and the second engagement roller 73 at the P6 of junction, than second telescopic sheet 31 Thickness and each thickness of first~third lower plate 25a~25c aggregate thickness it is small.By constituting as described above, path roller 71 and second engagement roller 73 can be clamped and squeeze second of telescopic sheet 31 and first~third lower plate 25a~25c, so as to Through-thickness compresses it.In addition, forming each periphery of path roller 71 and the second engagement roller 73 by elastomeric elements such as silicon rubber Face, to improve the mutual close property of peripheral surface at the P6 of junction.As a result, it is possible to make second of telescopic sheet 31 and One~third lower plate 25a~25c is more reliably integrally formed.

As described above, in the present embodiment, in the difference of the width direction of major diameter roller 70 and the peripheral surface of path roller 71 Position winds two telescopic sheets at spaced intervals, to being extended in the width direction with being wound onto on the peripheral surface of path roller 71 Transported two telescopic sheets of state, implement cutoff process, implement first~third lower plate 25a~25c engagement Processing.Therefore, two telescopic sheet implementations can be handled on same roller, so as to simplify manufacturing device.

＜ steps 4：The manufacture ＞ of 4th telescopic sheet 33

As shown in figure 5, there is air-breathing conveying device 80 and a pair of of third to connect in the device portion of the 4th telescopic sheet 33 of manufacture Close roller 81a, 81b.As shown in Fig. 2 D and Fig. 3 A, it is bonded to along the extension of the continuous direction of upper sheet 26 in the upper surface of upper sheet 26 Restraint zone 21 non-individual body（Hereinafter referred to as restraint zone 21）And the component formed, with have with third time telescopic sheet 32 the The mode of two lower plate 25b overlappings is engaged from top, to the 4th telescopic sheet 33 of manufacture.In addition, in figure 2d, upper The lower surface of portion's piece 26 applies bonding agent a5, and but it is not limited to this, can also apply and be bonded in the upper surface of the second lower plate 25b Agent can also all apply bonding agent in two on pieces.

Air-breathing conveying device 80 has：Absorbing gas belt 801（Endless belt）, driven roller 802, driven voller 803 and gettering container 804.Absorbing gas belt 801 is winded in driven roller 802 and driven voller 803, is horizontally extended along conveying direction.With motor (not shown) The driven roller 802 of connection rotates, so that absorbing gas belt 801 and driven voller 803 rotate.At this point, absorbing gas belt 801 with upper surface from The mode that the upstream side of conveying direction is downstream moved rotates.In addition, a pair of of third engagement roller 81a, 81b is conveyed compared to air-breathing Device 80 is arranged in the downstream side of conveying direction, is axial rotated with the width direction of third time telescopic sheet 32.

The third time telescopic sheet 32 engaged using path roller 71 and the second engagement roller 73, is hereafter wound onto second and connect It closes on the peripheral surface of roller 73 and is conveyed, and be fed into the upper surface of absorbing gas belt 801.Therefore, as shown in Figure 6 C, it is being supplied to To the initial period of absorbing gas belt 801, second of telescopic sheet 31 that third time telescopic sheet 32 has extends in the width direction.

In this, it is assumed that the state extended in the width direction with second of telescopic sheet 31 that third time telescopic sheet 32 has Restraint zone 21 and upper sheet 26 are engaged on third time telescopic sheet 32.Then, even if in rear process（Fig. 3 A）It is middle by the 4th The position of the width direction for the cut-out roller 90 that secondary telescopic sheet 33 is divided into two in the direction of the width matchingly supplies restraint zone 21 etc., may also cause after being engaged with third time telescopic sheet 32 restraint zone 21 relative to cut-out roller 90 in the direction of the width Position is staggered.Then, restraint zone 21 cannot be made to be uniformly present in be for one point in the direction of the width by the 4th telescopic sheet 33 Two and manufacture a pair of of flank 20a, 20b, become defective products, aesthetics be deteriorated.Then, in the present embodiment, make third After second of telescopic sheet 31 that secondary telescopic sheet 32 has is shunk, restraint zone 21 etc. is engaged on third time telescopic sheet 32.

Therefore, before engagement restraint zone 21 is equal, absorbing gas belt 801 flat upper table surface bearing and convey third time and stretch Contracting piece 32.By constituting as described above, second of telescopic sheet 31 that third time telescopic sheet 32 has can be made along width It shrinks in direction.In addition, by more leaning on the position in the downstream side of conveying direction that third engagement roller is arranged than air-breathing conveying device 80 81a, 81b, in third time telescopic sheet 32 after second of telescopic sheet 31 can be made to shrink in the width direction on absorbing gas belt 801 Upper engagement restraint zone 21 etc..

But if making 32 free shrink of third time telescopic sheet on absorbing gas belt 801, it is likely that stretched by for the second time The influence for the power that contracting piece 31 is acted on when shrinking, be folded in intermediate Filamentous elastomeric element 23 elongation multiplying power error Influence, and the position of the width direction of third time telescopic sheet 32 on absorbing gas belt 801 is caused to be staggered.Thus cannot be in third The appropriate location of the width direction of secondary telescopic sheet 32 with the second lower plate 25b overlappingly engages upper sheet 26, causes to fasten Central portion with 21 in the width direction is engaged with being staggered.It is flexible by the 4th time to which restraint zone 21 cannot be made to be uniformly present in Property piece 33 is divided into two in the direction of the width and a pair of of flank 20a, 20b for manufacturing.

Then, in the present embodiment, in the width for limiting the second lower plate 25b that third time telescopic sheet 32 has Third time telescopic sheet 32, second of telescopic sheet for making third time telescopic sheet 32 have are conveyed in the state of the position in direction 31 shrink on absorbing gas belt 801.Hereafter, restraint zone 21 is waited and is engaged with third time telescopic sheet 32.Therefore, in absorbing gas belt 801 Upper table surface bearing third time telescopic sheet 32, also, the second lower plate 25b is attracted and is adsorbed on the upper table of absorbing gas belt 801 Face（Conveyor surface）, to convey third time telescopic sheet 32.

Specifically, as shown in Figure 6 C, only in the central portion of the width direction of absorbing gas belt 801, i.e. the second lower plate 25b quilts The many suction holes 805 penetrated through along the thickness direction of absorbing gas belt 801 are arranged in the position of conveying.In addition, in absorbing gas belt 801 Side, setting for example attract the gettering container 804 of the air on absorbing gas belt 801 using fan (not shown) from suction hole 805.By such as The upper composition only can generate attraction in the central portion of the width direction of 801 upper surface of absorbing gas belt, so as to by second Lower plate 25b attracts and is adsorbed on the upper surface of absorbing gas belt 801.On the other hand, due to two of the width direction in absorbing gas belt 801 Suction hole 805 is not arranged for end, i.e. second of 31 transported position of telescopic sheet, and therefore, second of telescopic sheet 31 does not have Attracted and adsorbed by absorbing gas belt 801, the position of width direction is unrestricted.Therefore, it is possible to make second of 31 edge of telescopic sheet In the state of the position for the width direction that width direction limits the second lower plate 25b while contraction on conveying absorbing gas belt 801 Third time telescopic sheet 32.

As a result, it is possible in third time after making second of telescopic sheet 31 that third time telescopic sheet 32 has shrink Restraint zone 21 etc. is engaged on telescopic sheet 32.Therefore, the position phase with the width direction of the cut-out roller 90 of rear process can be inhibited The restraint zone 21 being matchingly supplied to misplaces in the direction of the width after being engaged with third time telescopic sheet 32.It is additionally possible to suppress The dislocation of the second lower plate 25b in the direction of the width on absorbing gas belt 801, so as in the width side of the second lower plate 25b To central portion engage restraint zone 21.Therefore, restraint zone 21 can be made to be uniformly present in the 4th telescopic sheet 33 in width A pair of of flank 20a, the 20b for being divided into two and manufacturing on degree direction.Accordingly it is also possible to which aesthetics is inhibited to deteriorate.In addition, it is not necessary that The position of the width direction of third time telescopic sheet 32 and restraint zone 21 is managed, apparatus structure can be simplified.

In addition, in order to flexible in third time after so that second of telescopic sheet 31 is shunk in the width direction on absorbing gas belt 801 Property piece 32 on engagement restraint zone 21 etc., more the position in the downstream side of conveying direction is being leaned on to be provided with a pair than air-breathing conveying device 80 Third engagement roller 81a, 81b.As a result, it is possible to which third time telescopic sheet 32 and the bonding station of the equal engagements of restraint zone 21 is made to connect Nearly cut-out roller 90.Restraint zone 21 can be alternatively inhibited to misplace in the direction of the width relative to cut-out roller 90 from this respect.

In addition, equal by until engaging until restraint zone 21 from being left air-breathing conveying device 80 in third time telescopic sheet 32 During, so that third time telescopic sheet 32 is vacantly conveyed.Therefore, in the present embodiment, convey and fill in air-breathing Set installation space between 80 and a pair of of third engagement roller 81a, 81b.It, can be in third time telescopic sheet by constituting as described above 32, which have no supportedly transported period, makes second of telescopic sheet 31 more reliably shrink.It therefore, can be flexible at second Property piece 31 contraction complete in the state of engaged with third time telescopic sheet 32 by restraint zone 21 is equal, can more reliably inhibit Restraint zone 21 misplaces relative to cut-out roller 90 in width direction.

Even if in addition, for example, between two second of the telescopic sheets 31 arranged at spaced intervals in the width direction not It engages the second lower plate 25b and only engages the upper sheet 26 for being provided with restraint zone 21, flank 20a, 20b can also be manufactured.But It is, it, can be before engagement restraint zone 21 waits, with lower plate 25b's by the way that lower plate 25b is arranged as present embodiment On the basis of the position of width direction, third time retractility is conveyed while so that second of telescopic sheet 31 is shunk in the width direction Piece 32.In addition, by engaging restraint zone 21 with the second lower plate 25b via upper sheet 26, flank 20a, 20b can be made to become Duplex, so as to improve intensity.Therefore, even if flank 20a, 20b are stretched when wearing disposable diaper 1, also may be used To prevent breakage.In other words, the second lower plate 25b becomes the third time telescopic sheet 32 when second of telescopic sheet 31 is shunk The position reference of width direction, also, play the role of improving the intensity of flank 20a, 20b.

In addition, in the present embodiment, third time retractility is conveyed using along the horizontal-extending absorbing gas belt 801 of conveying direction Piece 32, but it is not limited to this, for example, it is also possible to utilize roller conveying third time telescopic sheet 32.In addition, in order to limit the second lower part Second lower plate 25b is attracted and is adsorbed in absorbing gas belt 801 by the position of the width direction of piece 25b, and but it is not limited to this, for example, It can also carry out Electrostatic Absorption.In addition, the installation space between air-breathing conveying device 80 and a pair of of third engagement roller 81a, 81b, But it is not limited to this, and air-breathing conveying device 80 can also be made to be abutted with a pair of of third engagement roller 81a, 81b.Alternatively, it is also possible to Restraint zone 21 Deng is engaged on absorbing gas belt 801.

Alternatively, it is also possible to be not provided with air-breathing conveying device 80 and from the second engagement roller 73 to a pair of of third engagement roller 83a, So that the hanging state of third time telescopic sheet 32 is conveyed between 83b, it can also utilize and not have equal defeated of gettering container 804 Send device conveying third time telescopic sheet 32.In this case, although the position of the width direction of the second lower plate 25b cannot be limited It sets, but second of telescopic sheet 31 can be made to shrink.In addition, in the position for the width direction for not limiting the second lower plate 25b It, can also be by camera or sensor etc. to third time telescopic sheet 32 in the case of keeping second of telescopic sheet 31 contracted The position of width direction be managed.Alternatively, it is also possible to engage restraint zone 21 in the upstream side of the conveying direction of absorbing gas belt 801 Deng, restraint zone 21 etc. can also be engaged before so that second of telescopic sheet 31 is shunk.
