In the following description, the longitudinal direction of the absorbent body 6 (also in the longitudinal direction of the diaper 1) will be referred to as the X direction, and the transverse direction of the absorbent body 6 (also in the width direction of the diaper 1) will be described as the Y direction. Each of the pair of waist pieces 2 and 2 has a rectangular shape in a state of being spread in a planar shape. Each waist piece 2 has two sheets 3 and 4 and a plurality of linear elastic bodies 5 disposed between the two sheets 3 and 4. As shown in Fig. 1, each waist piece 2 is placed between two rectangular sheets 3 and 4 having the same shape and the same size, and is arranged at a substantially equal interval in the longitudinal direction (X direction) in the transverse direction (Y direction). The elastic body 5 is formed by being integrally fixed by a method such as an adhesive or fusion. In the natural state, the waist piece 2 formed in this manner forms a plurality of wrinkles which become the convex portions 2t extending in the longitudinal direction (X direction) by the contraction of the linear elastic body 5, thereby forming the uneven piece having the uneven structure. material. That is, in the waist piece 2, the extending direction (X direction) of the convex portion 2t intersects with the extending direction (Y direction) of the linear elastic body 5. More specifically, in the present embodiment, in the waist piece 2, the extending direction (X direction) of the convex portion 2t is orthogonal to the extending direction (Y direction) of the linear elastic body 5. The sheets 3 and 4 which are the waist sheets 2 which are the uneven sheets are usually used without any particular limitation as long as they are used for absorbent articles such as disposable diapers. For example, as the sheets 3 and 4, a laminated sheet of a non-woven fabric, a woven fabric, a film, or the like can be used. As the linear elastic body 5, a polymer comprising natural rubber, polyurethane, polystyrene-polyisoprene copolymer, polystyrene-polybutadiene copolymer, ethyl acrylate-ethylene, or the like can be used.

The two sheets 6a and 6b are joined between the two sheets 6a and 6b. The front sheet 6a and the back sheet 6b constituting the absorbent main body are generally used without any particular limitation as long as they are absorbent articles such as disposable diapers. For example, as the front sheet 6a, a hydrophilic and liquid-permeable nonwoven fabric or the like can be used, and as the back sheet 6b, a liquid impervious or water-repellent resin film or a laminate of a resin film and a non-woven fabric can be used. As the absorber 6c, it is possible to use an assembly of fibers such as pulp fibers coated with a water-permeable tissue or a non-woven fabric (or a nonwoven fabric) or to absorb particles of the water-absorbent polymer in an aggregate. Core and so on. Next, in a preferred embodiment of the method for producing an absorbent article of the present invention, a case of manufacturing the diaper 1 having the waist panel 2 having the above-described uneven structure will be described with reference to the drawings. 2 and 3, a manufacturing apparatus 100 preferably used for the manufacturing method of the diaper 1 is schematically shown. Further, as described above, since the waist piece 2 is continuously provided on the outer left and right sides of the back side portion B of the absorbent main body 6, a pair of right and left manufacturing apparatuses 100 are required, but the manufacturing apparatus 100 has the same configuration, and therefore Only one manufacturing apparatus 100 is shown in 2. In FIGS. 2 and 3, the direction indicated by the symbol x (x direction) indicates the transport direction (MD, Machine Direction), and the direction indicated by the symbol y (y direction) is orthogonal to the direction of the transport direction (x direction). . The conveying direction (x direction) is the same as the conveying direction of the continuous body of the diaper 1 to which the waist piece 2 is finally produced by the present embodiment. As shown in FIG. 2 and FIG. 3, the manufacturing apparatus 100 includes an interrupting transfer device 30 as a cutting device, and the cutting device includes an anvil roll 10 having a bottom knife 11 on a circumferential surface (surface) 10f and a surface thereof. The (circumferential surface) 20f has a cutter member 20 having a cutter 21 that is in contact with the bedknife 11. In the manufacturing apparatus 100 of the present embodiment, the cutter member 20 is a cutter roller 20 having a cutter 21 on the circumferential surface 20f. The anvil roll 10 and the cutter roll 20 rotate in opposite directions to each other in the manufacturing apparatus 100. The intermittent cutting transfer device 30 is configured to supply a continuous strip-shaped uneven sheet 2B having a concavo-convex structure to the anvil roll which is rotated in the opposite direction to each other so as to be wound around the circumferential surface 10f of the anvil roll 10 in the manufacturing apparatus 100. Between 10 and the cutter roll 20, the bottom knife 11 provided on the anvil roll 10 and the cutter roll 20 is brought into contact with the cutter 21, and the strip-shaped uneven sheet 2B is intermittently cut in the y direction; The waist sheet 2 which is formed into a short strip-shaped uneven sheet by the cutting is transferred and bonded to the strip-shaped front sheet 6a constituting the absorbent body 6 at a predetermined interval. In the intermittent cutting transfer device 30, it is necessary to intermittently transfer and bind the waist sheet 2 of the uneven sheet to the strip-shaped front sheet 6a. Therefore, by supplying the strip-shaped uneven sheet 2B at a speed slower than the rotational speed of the anvil roll 10, the strip-shaped uneven sheet 2B is slid on the circumferential surface 10f of the anvil roll 10, and the strip-shaped uneven sheet 2B is cut. Broken, thereby forming the waist sheet 2 of the uneven sheet. The anvil roll 10 that intermittently cuts the transfer device 30 is provided with a metal roll body 10B. As shown in FIG. 4, a groove 13 having a suction hole 12 is formed on the circumferential surface 10f of the roll body 10B, and the groove 13 corresponds to The position of the convex portion 2t of the waist piece 2 of the short strip-shaped uneven sheet is formed.

Further, a plurality of suction holes 12 are arranged at a predetermined interval in the bottom portion 13b of the groove 13. As shown in Fig. 2 to Fig. 4, the bottom blade 11 of the anvil roll 10 is disposed on the circumferential surface 10f so as to extend in the axial direction (y direction) of the roller body 10B, and is fixed in such a manner that the blade edge protrudes from the peripheral surface 10f. On the roller body 10B. In the manufacturing apparatus 100, a pair of bottom blades 11 are disposed at a position facing the roller body 10B. The groove 13 of the anvil roll 10 is formed on the circumferential surface 10f corresponding to the position of the convex portion 2t of the uneven sheet. Further, the extending direction of the convex portion 2t of the uneven sheet is the same direction as the extending direction of the groove 13 of the anvil roll 10. Here, the extending direction of the convex portion 2t of the uneven sheet is the extending direction of the convex portion 2t with respect to the conveying direction of the uneven sheet, and the direction of the groove 13 of the anvil roll 10 is the direction of rotation of the anvil roll 10 with respect to the direction of rotation of the anvil roll 10. Extend the direction. As described above, when the convex portion 2t and the groove 13 extend in the same direction, the uneven sheet can be stably conveyed. In the manufacturing apparatus 100, as shown in FIGS. 2 and 4, since the convex portion 2t extends in the transport direction (x direction), the groove 13 of the anvil roll 10 is formed to extend in the circumferential direction of the anvil roll 10. In this way, the grooves 13 extending in the circumferential direction of the circumferential surface 10f are disposed in plural in the axial direction of the roller body 10B in the manufacturing apparatus 100. From the viewpoint of stably conveying the formed waist piece 2, the groove 13 of the anvil roll 10 can be formed at least in the peripheral surface 10f of the anvil roll 10 and can be conveyed as a portion of the waist piece 2 of the short strip-shaped uneven sheet. However, in the manufacturing apparatus 100, as shown in FIGS. 2 and 4, not only the surface of the portion for conveying the waist sheet 2 but also the surface of the waist sheet 2 is also conveyed from the viewpoint of more stably conveying the strip-shaped uneven sheet 2B and the waist sheet 2. The surface formed on the portion of the belt-like uneven sheet 2B is formed over the entire circumference of the anvil roll 10 other than the portion where the bottom knife 11 is disposed. In the anvil roll 10 in which the groove 13 is formed over the entire circumference except for the portion of the bottom blade 11, the groove 13 has a first groove portion 131 and a second groove portion 132 formed in the bottom blade 11 The reference is the downstream side of the rotation direction of the roller, and the portion of the waist piece 2 formed by the cutting is conveyed. The second groove portion 132 is formed on the upstream side in the roller rotation direction with respect to the bottom blade 11 and conveys the strip-shaped uneven sheet 2B. Part of it. In the present embodiment, since the bottom blade 11 is disposed at a position facing each other, the roller body 10B is divided into a normal line that connects the center of the diameter of the roller body 10B provided to one of the opposing positions to the bottom blade 11. In the two portions, the first groove portion 131 is provided on the downstream side in the roller rotation direction of each of the bed blades 11, and the second groove portion 132 is provided on the upstream side in the roller rotation direction of each of the bed blades 11. Further, from the viewpoint of more stably conveying the strip-shaped uneven sheet 2B and the waist piece 2, the depth of the groove of the first groove portion 131 is formed to be larger than the depth of the groove of the second groove portion 132. In order to stably convey the strip-shaped uneven sheet 2B and the waist piece 2, it is preferable that the convex portion 2t easily enters into the groove 13 of the anvil roll 10. Therefore, as shown in FIG. 5, the groove width W1 of the groove 13 of the anvil roll 10 is preferably wider than the width W2 of the band-shaped uneven sheet 2B and the convex portion 2t of the waist piece 2. The width W2 of the convex portion 2t is the length at the widest position among the lengths of the orthogonal directions (y directions) of the convex portions 2t. From the same point of view, the ratio (W1/W2) of the groove width W1 of the groove 13 to the width W2 of the convex portion 2t is preferably 1. 1 or more, more preferably 2. 0 or more, and, preferably, 5. 0 or less, more preferably 3. 0 or less, specifically, preferably 1. 1 or more and 5. 0 or less, more preferably 2. 0 or more and 3. 0 or less. In particular, in the present embodiment, the strip-shaped uneven sheet 2B has two sheets 3 and 4 and a plurality of linear elastic bodies 5 disposed between the two sheets 3 and 4, and the convex portion 2t The extending direction intersects with the extending direction of the linear elastic body 5, and more specifically, in the natural state, by the contraction of the linear elastic body 5, a plurality of convex portions 2t extending in the longitudinal direction (X direction) are formed. Since the gap between the convex portion 2t and the groove 13 which enters the groove 13 is less likely to occur by the contraction force of the linear elastic body 5, the suction force is increased, and the strip-shaped uneven sheet 2B can be more stably conveyed. And waist piece 2. The lateral holes 14 of the anvil roll 10 are disposed at a predetermined interval in the circumferential direction of the rolls. Each of the lateral holes 14 is formed in a circular shape. Each of the horizontal holes 14 is formed in parallel with the axial direction of the roller body 10B, and penetrates from the one end surface 10e1 to the other end surface 10e2. Each of the horizontal holes 14 is closed by an annular sealing member (not shown) on the other end surface 10e2 side. The suction holes 12 of the anvil roll 10 are disposed corresponding to the respective horizontal holes 14 and extend between the horizontal holes 14 and the grooves 13. In other words, one end of the suction hole 12 communicates with the horizontal hole 14, and the other end thereof is disposed at the bottom portion 13b of the groove 13. The suction holes 12 are disposed at the bottom portion 13b of the groove 13, and therefore, in the manufacturing apparatus 100, as shown in Fig. 4, are disposed at intervals in the circumferential direction of the anvil roll 10, and are spaced apart from each other in the axial direction of the roll body 10B. And configuration. Each of the suction holes 12 is formed in a circular shape. A suction ring (not shown) is disposed on one end surface 10e1 of the anvil roll 10. A suction ring (not shown) is fixed to the side of the end surface 10e1 of one of the pair of drive shaft support members (not shown) that rotatably supports the roller body 10B of the anvil roll 10. That is, the suction ring (not shown) does not rotate together with the anvil roll 10. Further, a suction ring (not shown) is formed as a disk body having substantially the same diameter as the diameter of the roller body 10B. The suction ring (not shown) has a plurality of mutually independent spatial regions therein, and the manufacturing apparatus 100 has three spatial regions, a space region a, a space region b, and a space region c, as shown in FIG. The space area a of the suction ring (not shown) corresponds to the cutting of the bottom blade 11 and the cutter roller 20 which feed the strip-shaped uneven sheet 2B wound in the state of the circumferential surface 10f to the anvil roll 10 in the anvil roll 10. The area between the knives 21. Further, the space region b of the suction ring (not shown) corresponds to the waist sheet 2 of the anvil roll 10 which is cut into a strip-shaped uneven sheet by the anvil roll 10 and the cutter roll 20, and is attached to the front side of the belt. The area up to the sheet 6a. The space area c of the suction ring (not shown) corresponds to the area of the anvil roll 10 in which the waist piece 2 is bonded to the strip-shaped front sheet 6a and then the band-shaped uneven sheet 2B is received again. An intake fan (not shown) is connected to a suction ring (not shown), and by driving the intake fan, the pressures of the spatial region a, the space region b, and the space region c which are independent of each other can be adjusted. In 100, the space area a is maintained at a negative pressure, the space area b is maintained at a negative pressure higher than the space area a, and the space area c is maintained at atmospheric pressure (pressure is zero). The suction air generated by the intake fan (not shown) is passed through the suction ring (not shown) to the lateral hole 14 formed in the roller body 10B of the anvil roll 10. Further, the suction air is passed through the horizontal hole 14 to the suction hole 12 disposed in the bottom portion 13b of the groove 13 formed in the circumferential surface 10f of the roller body 10B. Therefore, in the spatial region a of the suction ring (not shown), the strip-shaped uneven sheet is made by the suction air that is passed to the suction hole 12 through the plurality of lateral holes 14 located at the position corresponding to the space region a. 2B is sucked to the surface 10f of the anvil roll 10. Then, in the space region b of the suction ring (not shown), the waist piece 2 is sucked by the suction air that is passed to the suction hole 12 through the plurality of transverse holes 14 located at the position corresponding to the space area b. To the surface 10f of the anvil roll 10. Further, since the suction ring (not shown) is fixed to the drive shaft support member (not shown) independently of the anvil roll 10, the position of the space area a, the space area b, and the space area c even if the anvil roll 10 rotates. It will not change, and the range through which the suction air passes is always fixed. The cutter roller 20 that intermittently cuts the transfer device 30 is a metal roller, and is disposed adjacent to the anvil roll 10 so as to sandwich the strip-shaped uneven sheet 2B as shown in FIGS. 2 and 3 . In the manufacturing apparatus 100, the cutter rolls 20 are disposed so as to be in contact with one of the anvil rolls 10 and the bottom blades 11, 11 to cut the strip-shaped uneven sheets 2B by the pair of cutters 21 and 21. The pair of cutters 21 and 21 are disposed at positions facing each other of the cutter roller 20, and are fixed so that the blade edge protrudes from the surface 20f of the roller body 10B. The cutter roll 20 is rotated in the reverse direction with the anvil roll 10, and is rotationally controlled so that the respective cutters 21, 21 are in contact with the bottom blades 11, 11 of the anvil roll 10. That is, during the one rotation of the anvil roll 10 and the cutter roll 20, one cutter 21 is in contact with one bottom knife 11, and the other cutter 21 is in contact with the other bottom knife 11, with respect to the anvil roll. 10 The rotation of the cutter roller 20 described above is performed. The manufacturing apparatus 100 has a pair of driving rollers 41 and 42 that supply the strip-shaped uneven sheet 2B to the anvil roll 10. The rotation of the driving rollers 41, 42 is controlled such that the supply speed of the strip-shaped uneven sheet 2B is slower than the peripheral speed of the anvil roll 10. Next, a method of manufacturing the diaper 1 having the waist sheet 2 having the uneven structure using the above-described manufacturing apparatus 100 will be described. The method for producing an absorbent article of the present invention includes a conveying step of conveying the uneven sheet to a belt-shaped sheet as a belt-shaped conveyed material. In the manufacturing method of the diaper 1, the strip-shaped uneven sheet 2B and the stretchable waist sheet 2 correspond to the above-mentioned uneven sheet, and the strip-shaped front sheet 6a corresponds to the above-mentioned strip-shaped sheet (belt-shaped conveyed object). In the transporting step of the present embodiment, the intermittent cutting transfer device 30 is provided, and the intermittent cutting transfer device 30 is provided with an anvil roll 10 having a bottom knife 11 on the circumferential surface 10f and having a contact with the bottom knife 11 on the surface 20f. The cutter member of the cutter 21 is the cutter roller 20. Hereinafter, a method of manufacturing the diaper 1 of the present embodiment using the manufacturing apparatus 100 will be specifically described. The strip-shaped uneven sheet 2B which is a raw material of the elastic waist sheet 2 can be produced, for example, by the method for producing a stretchable sheet described in JP-A-2012-090835, JP-A-2012-090836, and the like. Manufacturing. The strip-shaped uneven sheet 2B produced by such a manufacturing method has the convex portion 2t extending in the longitudinal direction (X direction) by the contraction of the linear elastic body 5. In addition, before the strip-shaped uneven sheet 2B is wound around the circumferential surface 10f of the anvil roll 10, an adhesive is applied to a portion of the strip-shaped back sheet 6b. First, in the space area a and the space area b of the suction ring (not shown) of the manufacturing apparatus 100, the connected intake fan (not shown) is actuated to become a negative pressure. By making the space area a of the suction ring (not shown) and the space area b into a negative pressure, the suction air is passed through a plurality of horizontal holes 14 located at positions corresponding to the space area a and the space area b. The suction hole 12 of the groove 13. The uneven sheet is sucked to the surface 10f of the anvil roll 10 by suction air from the suction holes 12. Then, the anvil roll 10 provided in the intermittent cutting transfer device 30 is rotated, and the cutter roller 20 provided in the intermittent cutting transfer device 30 is rotated in the opposite direction to the rotation direction of the anvil roll 10. Further, in the present embodiment, the strip-shaped front sheet 6a is fed to the downstream side of the roll rotation direction of the anvil roll 10 at the same supply speed as the peripheral speed of the anvil roll 10 (including a suction ring (not shown)). The portion of the space area b and the space area c is transported. Then, the strip-shaped uneven sheet 2B is supplied to the circumferential surface 10f of the anvil roll 10 by the pair of driving rollers 41 and 42. Here, by controlling the rotation of the driving rollers 41, 42, the strip-shaped uneven sheet 2B is supplied to the circumferential surface 10f of the anvil roll 10 at a supply speed slower than the peripheral speed of the anvil roll 10. The strip-shaped uneven sheet 2B supplied to the circumferential surface 10f of the anvil roll 10 is sucked by the suction air from the suction hole 12 of the groove 13 to the anvil at a position corresponding to the space area a of the suction ring (not shown). The surface 10f of the roller 10 is wound around the circumferential surface 10f. Then, the strip-shaped uneven sheet 2B is conveyed between the bottom knife 11 of the anvil roll 10 and the cutter 21 of the cutter roll 20 while being wound around the surface 10f of the anvil roll 10. As described above, since the supply speed of the strip-shaped uneven sheet 2B is slower than the peripheral speed of the anvil roll 10, the strip-shaped uneven sheet 2B is conveyed to the bottom knife 11 and the cutter while sliding on the circumferential surface of the anvil roll 10. Between 21 . Here, the circumferential surface 10f of the anvil roll 10 used in the transporting step of the present embodiment has the groove 13 having the bottom portion 13b and the suction hole 12, and the groove 13 is formed corresponding to the position of the convex portion 2t of the uneven sheet 2B. . Further, in the transporting step of the present embodiment, as shown in FIG. 5, the strip-shaped uneven sheet 2B is sucked by the suction holes 12 of the anvil roll 10 to be transported. It is preferable to carry out the conveyance in a state where the convex portion 2t of the strip-shaped uneven sheet 2B enters the groove 13 of the circumferential surface 10f of the anvil roll 10. In the present embodiment, the strip-shaped uneven sheet 2B is conveyed while the convex portion 2t of the strip-shaped uneven sheet 2B is placed in the groove 13 of the anvil roll 10, so that it can be stably conveyed to the anvil. The bottom knife 11 of the roller 10 is between the cutter 21 of the cutter roller 20. Therefore, the diaper 1 can be stably produced. Further, the strip-shaped uneven sheet 2B has two sheets 3 and 4 and a plurality of linear elastic bodies 5 disposed between the two sheets 3 and 4 in an extended state, and the extending direction and linear elasticity of the convex portion 2t The extension direction of the body 5 intersects. Specifically, in the belt-like uneven sheet 2B, in the natural state, a plurality of wrinkles which are the convex portions 2t extending in the longitudinal direction (X direction) are formed by the contraction of the linear elastic body 5. Therefore, when the convex portion 2t of the strip-shaped uneven sheet 2B is conveyed in the state of being in the groove 13 of the circumferential surface 10f of the anvil roll 10, the contraction force of the linear elastic body 5 enters the groove 13 When the gap between the convex portion 2t and the groove 13 is less likely to occur, the suction force to the strip-shaped uneven sheet 2B is improved, and the strip-shaped uneven sheet 2B can be conveyed more stably. Then, the strip-shaped uneven sheet 2B conveyed between the bottom knife 11 of the anvil roll 10 and the cutter 21 of the cutter roll 20 is cut by the contact of the bottom knife 11 with the cutter 21, and is formed as a short The waist piece 2 of the strip-shaped uneven sheet.
