Then, the abdomen exterior strip member 171 and the dorsal exterior strip member 172 in a superposed state are welded in a predetermined region. The welding is performed by heat seal welding or ultrasonic welding using a welding apparatus (not shown). Then, the diaper 1 is manufactured by cutting the abdominal exterior strip member 171 and the back exterior strip member 172 together along the CD direction using the cutting device (not shown) as a reference along the CD direction. Is done.

  In the present embodiment, the cut forming process (S102) is performed after the material conveyance / thread rubber arranging process (S101) and before the ventral backside exterior belt-shaped member forming process (S103) and the thread rubber cutting process (S102). Therefore, it is possible to reduce the influence of the material conveyance deviation caused by the ventral dorsal exterior belt-shaped member forming step and the thread rubber cutting step, and to further reduce the risk that the formation position of the cut 15 is shifted. it can.

  Further, since the cut forming device 24 including the cut roll 241 for forming the cut 15 and the thread rubber cutting device 26 including the cut roll 261 for cutting the thread rubber 141 are provided separately, The vibration at the time of forming the cut 15 reduces the possibility that the rubber thread 141 cannot be cut at an accurate position or the rubber thread 141 cannot be cut reliably. When the rubber thread 141 is cut, the rubber thread 141 contracts from the cut portion toward the cut portion SL in the MD direction (so-called “cutback”), and it is difficult to accurately control the movement. If the cut rubber thread 141 is present at the place where the cut 15 is to be formed, the formation of the cut 15 will be obstructed, resulting in a situation in which the cut 15 cannot be formed accurately. Therefore, the cut 15 is formed without being affected by the cut rubber thread 141 by performing the thread rubber cutting process (S104) after the cut forming process (S102) as in the present embodiment. be able to.

  Further, by performing the rubber thread cutting step (S104) after the ventral backside exterior belt-like member forming step (S103), the rubber thread 141 is separated after being separated into the abdominal exterior belt-like member 171 and the backside exterior belt-like member 172. Therefore, the position of cutting the rubber thread 141 in the abdominal exterior strip member 171 and the back exterior strip member 172 can be made different. For this reason, the diaper 1 provided with the stretching force suitable for each of the stomach side and the back side can be manufactured.

=== Second Embodiment ===
In the second embodiment, another method for manufacturing the diaper 1 will be described.
Drawing 6 is a figure showing the flow of each process of the production line of diaper 1 in a 2nd embodiment. As shown in FIG. 6, in the second embodiment, the diaper 1 includes material conveyance / thread rubber placement (S201), ventral backside exterior belt-shaped member forming step (S202), cut formation / thread rubber cutting step (S203). This is manufactured by the absorbent main body arranging step (S204), the two-folding / welding / cutting step (S205).

  Hereinafter, each process of the manufacturing line of the diaper 1 of 2nd Embodiment is demonstrated in order. FIG. 7A is a schematic diagram illustrating a flow of a manufacturing method of the diaper 1 of the second embodiment. FIG. 7B is a schematic diagram illustrating the exterior strip member 17 in each step in FIG. 7A.

  First, in the material conveyance / thread rubber placement step (S201) as in the first embodiment, the material of the diaper 1 is conveyed along the MD direction by an appropriate conveyance mechanism, and each material is arranged at a predetermined position. As shown in FIG. 7A, a plurality of thread rubbers 141 transported from the thread rubber roll 23 are arranged on the skin side belt-shaped member 18 transported from the skin side member roll 21 in a state of being stretched in the MD direction. Furthermore, the non-skin side belt-like member 19 conveyed from the non-skin side member roll 22 is disposed thereon, and the skin-side belt-like member 18, the thread rubber 14, and the non-skin are adhered by the adhesive applied to the thread rubber 14. The side band members 19 are bonded to each other to form the exterior band member 17.

  Next, in the abdominal side dorsal exterior member forming step (S202), the exterior band member 17 is separated at the approximate center of the CD direction by using the separating device 25 that cuts the exterior band member 17 along the MD direction. A side exterior strip member 171 and a back exterior strip member 172 are formed. The separation device 25 has the same configuration as that of the first embodiment. Thus, when the exterior member 17 is cut at the position e in FIG. 7A, it is separated into the abdominal exterior strip member 171 and the back exterior strip member 172 at the position e in FIG. 7B.

  Subsequently, in the cut formation / thread rubber cutting step (S203), the cut formation / thread rubber cutting device 27 is used to form a plurality of cuts 15 on the abdominal exterior strip member 171 and the back exterior strip member 172, respectively. Then, the rubber thread 141 is cut. Two cut forming / thread rubber cutting devices 27 are installed side by side in the CD direction, and the slit forming / thread rubber cutting device 27a and the dorsal outer band member 172 are processed to process the ventral outer band member 171. A thread rubber cutting device 27b is provided.

  FIG. 8 is a DD arrow view in FIG. 7A. As shown in FIG. 8, the cut forming / thread rubber cutting devices 27a and 27b include cutter rolls 271a and 271b and anvil rolls 272a and 272b, respectively. The anvil rolls 272a and 272b are rotating bodies having the same configuration as the anvil roll 242 of the cut forming device 24 of the first embodiment, and a plurality of anvil blocks (not shown) are provided on the circumferential surface thereof. The cutter rolls 271a and 272b are rotating bodies arranged at positions opposite to the anvil rolls 272a and 272b, respectively, and include cutter blocks 274a and 274b and cutter blocks 276a and 276b in the circumferential direction, respectively. Each cutter roll 271a, 271b rotates in the opposite direction while each anvil roll 272a, 272b rotates, so that the anvil block and each cutter block 274a, 274b, 276a, 276b are periodically opposed to each other. Become. The cutter blocks 274a and 274b are each provided with a plurality of cutter portions 275a and 275b along the conveying direction, and the cutter portions 275a and 275b and the anvil block face each other so that the abdominal exterior strip member 11 and the back exterior strip member The cut 15 can be formed when contacting the 172. Also, the cutter blocks 276a and 276b are provided with a plurality of cutter portions 277a and 277b, each of which is inclined at a certain angle with respect to the conveying direction, and the cutter portions 277a and 277b and the anvil block face each other to form a ventral-side exterior belt-like member. 171, the rubber thread 141 is cut when contacting the backside exterior belt-like member 172.

  Thereafter, as in the first embodiment, in the absorbent main body arranging step (S204), the absorbent main body 13 is arranged on the skin side belt-like member 18 side of the abdominal-side outer belt-like member 171 and the back-side outer belt-like member 172, and bonded. It is joined to the surface of the skin-side band-shaped member 18 of the abdominal-side exterior band-shaped member 171 and the back-side exterior band-shaped member 172 by an agent or the like.

  Then, as in the first embodiment, the diaper 1 is manufactured by the half-folding / welding / cutting step (S205).

  Thus, after the step of disposing the rubber thread 141 between the skin-side belt-like member 18 and the non-skin-side member 19, the cut rubber 15 is formed from the cut 15 to the rubber thread 14 due to the displacement of the position that occurs during material conveyance. The risk of seeing can be reduced. Moreover, in order to improve air permeability, it is preferable that the cut | interruption 15 has penetrated the skin side strip | belt-shaped member 18 and the non-skin side strip | belt-shaped member 19, and the shape of the cut | interruption 15 is a shape along a conveyance direction. It is preferable.

  In the present embodiment, since the cut 15 is formed and the rubber thread 141 is cut by the same cut forming / thread rubber cutting device 27, the diaper 1 can be manufactured on a more compact production line. In addition, since the exterior belt-like member 17 is separated into the abdominal exterior belt-like member 171 and the back-side exterior belt-like member 172, the cut 15 is formed and the thread rubber 141 is cut. The cutting pattern can be made different between the ventral side and the dorsal side.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof. For example, the following modifications are possible.

  The material conveying / thread rubber arranging step (S101) and the cut forming step (S102) in the first embodiment may be performed while conveying on one rotating body. FIG. 9A is a schematic diagram illustrating a flow of a method for manufacturing the diaper 1 of another embodiment. As shown to FIG. 9A, the skin side member roll 21, the non-skin side member roll 22, the rubber thread roll 23, the anvil roll 30, the roll 31 which is a drum-shaped rotary body, and the cutter of the cut forming apparatus 24 in the first embodiment Using the cutter roll 32 having the same configuration as the roll 24, the material conveyance / thread rubber placement step (S101) and the cut formation step (S102) are performed. The roll 31 is disposed to face the anvil roll 30, and the cut roll 32 is disposed to face the anvil roll 30.

  As shown in FIG. 9A, first, the non-skin side member 19 conveyed from the non-skin side member roll 22 is placed on the anvil roll 30. Next, at a position advanced a predetermined distance in the MD direction from the position where the non-skin side band-shaped member 19 on the anvil roll 30 is placed, the plurality of thread rubbers 141 conveyed from the thread rubber roll 23 are expanded in the MD direction. In the state, it is arranged from above the non-skin side belt-like member 19. Subsequently, the skin-side belt-like member 18 conveyed from the skin-side member roll 21 is placed from above the thread rubber 141 at a position advanced by a predetermined distance in the MD direction from the position where the thread rubber 141 is disposed on the anvil roll 30. Is done. And while conveying on the anvil roll 30 in MD direction, it passes between the anvil roll 30 and the roll 31, and adheres the skin side belt-like member 18, the thread rubber 141, and the non-skin side belt-like member 19, and it is an exterior belt shape. The member 17 is formed. Then, when the cutter part (not shown) of the cutter roll 32 and the anvil roll 30 face each other and come into contact with the exterior belt-shaped member 17, a cut 15 is formed.

  In this way, the distance from the placement of the rubber thread 141 to the formation of the cut 15 by performing the material conveyance / thread rubber placement step (S101) and the cut formation step (S102) on one anvil roll 30. Can be shortened, and the displacement of the position caused by the conveyance of the material can be reduced. Moreover, the production line of the diaper 1 can be made more compact.

  Further, the anvil roll 30 has a plurality of protrusions 301 protruding outward in the radial direction, and the outer belt-shaped member up to the roll 31 and the cut roll 32 in a state where the rubber thread 141 is inserted between the adjacent protrusions 301. 17 may be conveyed. FIG. 9B is a schematic cross-sectional view showing the EE cross section of FIG. 9A. As shown in FIG. 9B, the anvil roll 30 includes a plurality of protrusions 301 so that the surface thereof has an uneven shape. The protrusion 301 is formed along the peripheral surface of the anvil roll 30, and the concave portion 302 that is a recessed portion is also formed along the peripheral surface of the anvil roll 30. The protrusions 301 and the recesses 302 are alternately formed with protrusions (protrusions) and recesses when viewed in the axial direction of the anvil roll 30. The recess 302 is a groove into which the thread rubber 14 stretched in the MD direction can be inserted along the MD direction, and has a width and a depth that allow the thread rubber 141 to enter. The thread rubber 141 disposed on the anvil roll 30 is conveyed to a position facing the cut roll 32 with the thread rubber 141 placed in the recess 302. The state where the thread rubber 141 is inserted into the recess 302 means a state where at least a part of the thread rubber 141 enters the recess 302 as shown in FIG. 9B. Accordingly, the non-skin side belt-like member 19 located on the anvil roll 30 side is also uneven in the thickness direction and partially enters the recess 302.

  Since the thread rubber 141 is transported in a state where the thread rubber 141 is inserted into the recess 302, the thread rubber 14 disposed in the material transport / thread rubber placement step (S101) can be transported with reduced risk of shifting, so that a cut is formed. In the step (S102), the cut 15 can be formed at a more accurate position. Thereby, the possibility that the cutter part 321 of the cutter roll 32 may come into contact with the position where the rubber thread 141 is disposed can be reduced, and the possibility that the rubber thread 14 can be seen from the cut 15 can be further reduced. Further, since the position of the thread rubber 141 can be determined on the anvil roll 30, the thread rubber 141 can be accurately arranged without using an adhesive for fixing the thread rubber 14, and as a result, it is softer. The diaper 1 can also be manufactured.

  At this time, it is preferable that the non-skin side belt-like member 19 positioned on the anvil roll 30 side is conveyed in a state of being in contact with only the protrusion 301 and the cut 15 is formed in the exterior belt-like member 17. That is, it is preferable that the exterior belt-shaped member 17 does not contact the most recessed portion of the recess 302. In this way, even when an adhesive is applied to the thread rubber 14, the risk of the adhesive adhering to the anvil roll 30 can be reduced, and maintenance management such as cleaning of the apparatus is facilitated.

  In addition, in the above-mentioned embodiment, although the cut | interruption 15 shall penetrate the exterior member 10, it is not restricted to this. The cut line 15 may be provided on either the ventral-side exterior member 11 or the back-side exterior member 12, and does not penetrate the exterior member 10, and is provided on either the skin-side member 181 or the non-skin-side member 191. The cut 15 may be formed. Forms a cut 15 that penetrates the portion that tends to accumulate moisture to improve air permeability, and forms a cut 15 in either the skin-side member 181 or the non-skin-side member 191 for a portion that is difficult to accumulate moisture. May be increased.

  Furthermore, in the above-described embodiment, the folded portion FL formed by folding the non-skin side member 191 is formed on the vertical end 1he, but this is not restrictive. A reinforcing member can be added to the vertical end 1he to improve the strength of the waistline opening 1HB.
