You will understand the following features at least clearly from the accompanying specifications and figures. In the following description; What was revealed was a disposable nappy with a vertical direction and a side direction that crossed with the vertical direction; Disposable nappy included: Absorbent main body

5 litters; Back waist section placed on one end side of the absorbent main body; and a frontal waist section on the other end side of the absorbent main body; both end parts are joined

the lateral end parts of the rear waist section and each of the lateral end parts of the front waist section in succession to each other” cut-off part fitted in a lateral central ein of the upper vertical end part of the front waist section; A part in which the number of layers is greater than the number of layers in the vertical lower end gall of the front waist section is fitted vertically higher than the cut lower end of the shall of the front waist section. According to this disposable nappy; For the part in which the number of layers is greater than in all the lower extremities has been prepared in each of the lateral sides with a shall cut in the front waist section; The stiffness increases in this part. and so when each of the lateral end-parts of the anterior waist-section and each of the lateral-end-parts of the rear waist-section are respectively joined to 0 each other in a condition in which the anterior waist-section is drawn in the lateral direction; The upper end section is less likely to curl down. Accordingly; It is possible to suppress deviation in the joined parts between each of the lateral end parts of the anterior waist section and each of the lateral end parts of the rear waist section. In a disposable nappy described (LT) it is desirable that the section in which the number of layers is greater than the number of layers be fitted in the lower end gag of the front waist section across an area from the edge of the cut gall to each of the side end sections For the front waist section in the side direction dg For this disposable nappy the part is prepared in which the number of layers is greater than that of the lower end gall across the area from the edge of the cut gall to each of the 0 end parts lateral end parts of the front waist section at each of the lateral sides of the cut section of the front waist section;therefore stiffness increases over the entire length in the lateral direction.Therefore, when both the lateral end parts of the front waist section and each of the lateral end parts of the rear waist section are respectively joined to each other in a situation where the front waist section is pulled in a lateral direction; the upper end hall of the front waist section is less likely to curl downward.

in the disposable nappy described above; It is desirable that a lower limb be placed

For the part where the number of layers is greater than the number of layers in the lower end gall of the waist section

Anterior vertically inferior to the extremities (gall aud) cut off.

According to that disposable nappy; Then the part in which the number of layers is greater than that of the lower end gall extending downward from the lower end of the gall is cut in

front waist section; Hence the part has a high stiffness which increases in the vertical direction. Accordingly; when done

Join each of the side end parts of the front waist section and each of the side end parts of the front waist section

The back waist is straight to each other in a situation where the front waist section is pulled in

lateral direction; The upper end portion of the front waist section is less likely to curl downward.

0 In a disposable nappy described as 'lil' it is desirable that the lower end of the gall of which the number of layers is greater than the number of layers of the lower end of the gall of the front waist section be placed vertically lower than the upper end of the main absorbent body. According to that disposable nappy; It is a hall setup in which the number of layers is greater than that of the upper terminal gall to a position where the gall overlaps with the body

5 main (ald) in the front waist section; Hence the part has a high stiffness which increases in the vertical direction. Accordingly; when each of the lateral end-parts of the anterior waist-section and each of the lateral-end-parts of the rear waist-section are respectively joined together in such a state that the front-waist-section is drawn laterally; The upper end of the front waist section is less likely to curl down.

0 in the disposable folder described above; It is desirable that the main absorbent body include an absorbent core in it; The lower end of the part where the number of layers is greater than the number of layers is placed in the lower end of the front waist section vertically lower than the upper end of the absorbent core according to that disposable diaper; it; Since the part in which there is a number is processed

5 the layers are larger than those of the terminal gall (lower above) to a position where the oad) overlaps with the absorbent core of rigidity; in aud front waist; The part has a high hardness that increases in the direction

vertical. Accordingly; when each of the lateral end-parts of the anterior waist-section and each of the lateral-end-parts of the rear waist-section are respectively joined together in such a state that the front-waist-section is drawn laterally; The upper end portion of the front waist section is less likely to curl downward.

In a disposable nappy described Ail it is desirable that the front waist section includes a csheet member and the part where the number of layers is greater than the number of layers in the glad) the lower end of the front waist section includes a folded portion Formed fold down the gall the upper vertical end of the perch organ. Ga, for that disposable nappy; it; The formed folded part forms a fold downward

0 the upper terminal part of the perch member of the anterior waist section the part in which the number of layers is greater than that of the lower terminal part of the anterior waist section; This eliminates the need to prepare the chick organ separately to increase the number of layers, so that the number of materials can be reduced. In a diaper using the single Sad described above; It is desirable that the anterior waist section include a perch member; The part in which the number of layers is greater than the number of layers in 5 the lower end part andl the anterior waist shall be fitted with a different stern member than the stern member forming all the lower extremities. According to that disposable nappy; it is a formation (gral) in which the number of layers is greater than that of the gall of the lower end of the anterior waist section by the insertion of a separate stern member other than the stern member which forms the lower end of the anterior waist section; with which it is possible to manufacture 0 disposable diapers; eliminates the edge for interlocking operation; For example; lie in a state in which that part is formed by folding the chick's organ. in the disposable nappy described above; It is desirable that the upper end of the part in which the number of layers is greater than the number of layers of the lower end of the front waist section be placed vertically lower than the upper end of the front waist section. 5 According to that nappy using one Spal; He placed the upper end of the part in which the number of layers is greater than that of the gall, the lower end of the front waist section vertically lower than

the upper end of the front waist section; In the words (AT) the upper end gall of the front waist section is not the part in which the number of layers is greater than that in the lower end part of the front waist section, so that the stiffness is reduced in the vicinity of the middle hole and thus the Sage is to improve a soft texture .soft texture

In the disposable diaper described as Ail, it is desirable that the front waist section include an elastic member placed on each side of the ils of the cut part and vertically higher than the lower end of the part cp shall, since the elastic member is subject to contraction For stretching in the lateral direction. According to this disposable nappy; The anterior waist section shall have a stiff elastic member

0 which is placed on each lateral side of the cut portion and above the lower end of the cut portion vertically; To increase the stiffness in the upper end gall of the anterior waist section. Accordingly; when each of the lateral end-parts of the anterior waist-section and each of the lateral-end-parts of the rear waist-section are respectively joined together in such a state that the front-waist-section is drawn laterally; The upper end hall of the front waist section is less likely to curl down.

5 In the disposable nappy described above it is desirable that the elastic member be fitted in the part where the number of layers is greater than the number of layers in the lower end gall of the front waist section. According to this disposable nappy; The rigid elastic member shall be prepared in the part where the number of layers is greater than that of the lower end gall of the front waist section, so that

0 increases the stiffness in this part. Accordingly; when each of the lateral end-parts of the front waist-section and each of the lateral-end-parts of the rear waist-section are joined respectively to each other in such a state that the front waist-section is drawn in the lateral direction; The upper end gall of the front waist section is less likely to curl down. A method was discovered to manufacture a disposable nappy with a vertical direction and a lateral direction that intersects with

5 directional (ul) disposable nappy includes an absorbent main body (clad) rear waist section placed on one end side of the absorbent main body;

front placed on another end side of the main body gall The method includes: a first operation to increase the number of seams on a higher side of the ga vertical lower end of the front waist section; dee a second to form the ga cut into a lateral central part sal upper vertical end of the anterior waist section after the first operation; and a third load to join each of the lateral end parts of the posterior waist section and each of the lateral end parts of the anterior waist section respectively to each other after the dead (dnl where in the second operation; the cut hall is formed so that the lower end is placed The cut gall is inferior to an upper end ad having a greater number of layers formed in the first process. Gy For this method of manufacturing a disposable nappy the cut chad is shaped and each of the 0 side end parts of a section is joined the posterior waist and each of the lateral end parts of the anterior waist section respectively to each other; In a case where the stiffness increases by increasing the number of layers on the upper side of the lower extremity gall of the front waist section. Accordingly; The upper end of the front waist section is less likely to curl down at the time of this retraction; Thus the Sage is to suppress deflection in the joined portions between each of the lateral end portions of the front waist section and each of the lateral end portions of the rear waist section. 1st embodiment A disposable nappy worn on a newborn child will be described as a disposable nappy 1 according to a first embodiment of the present disclosure (hereinafter simply referred to as 'alia' 1) eg. 0 <nappy configuration 1> « Yl The configuration of Diaper 1 will be described based on Figures 1 to 3. Figure 1 is a schematic perspective view showing a representative formation of Diaper 1. Figure 2 is a schematic top view showing Diaper 1 in an unfolded and flat state as seen from the skin side of the wearer. 3 is a cross sectional view taken along line 3-3 of Fig. 2. 5 of a diaper 1" uly 'lateral direction' intersecting with the vertical direction as shown in Figure 1; and 'thickening direction' as shown in Figure 3. In the vertical direction; the side will be indicated by the loin

The wearer's side will be referred to as 'upper side'; the wearer's adie side will be referred to as 'underside'. Additionally, assuming the wearer is Diaper Gal 1; the side in front of the wearer will simply be referred to as 'front side'” and the Simply referring to the side on the wearer's back as the "back side". "Thickening direction" refers to the direction in which the members of diaper 5 1 are made in layers. Assuming the wearer is wearing nappy 1; The side that is in contact with the wearer's skin will be referred to as the "skin side"; The side opposite to the opposite side will be referred to as the "no-skin side". Nappy 1 is assumed to be the so-called three-piece type of nappy with the absorbent main body strip-Fig. 10; Back waist section 20 to tuck into the wearer's back; And a 30 0 front waist section to be tucked in front of the wearer. As shown in Figure 2; in nappy 1 unfolded; The posterior waist section 0 is placed on one longitudinal end side 10 of the absorbent main body 10; The anterior waist section 30 is placed on the other longitudinal side 10b of the absorbent main body 10. In other words; The absorbent main body 10 unfolds between the back waist section 20 and the front waist section 30 spaced apart. The absorbent main body 10 of the diaper 1 is folded in half dws to its longitudinal center so that the upper end 1 of the rear waist section 20 and the upper end 301 of the front waist section align with each other. and then; Two side end parts 200 of the rear waist section 20 and two side end parts 300 of the front waist section 0 30 are joined together; To prepare a disposable diaper with a single side hole 1 HP 1118 and two leg openings 1 HL.111 (see fig. 1). in this way; A tight shawl pair 100 is formed by joining each of the lateral end parts 200 of the rear waist section 20 and each of the lateral end parts 300 of the front waist section 30 respectively to each other as shown in Figure 1. 5 A large number of spandex members are prepared. clastic members placed along the lateral direction in the back waist section 20 andy the front waist 30. By contracting the abundance of elastic members in the direction

lateral when wearing a nappy 1; Diaper 1 adjusts to the wearer's back waist and front waist for better fit. Note that Diaper 1 Alla is flat in the unfolded state of Figure 2. Hana “flat state” refers to a state in which the back waist section 20 and the front waist section 30 are stretched without wrinkles by the generous stretching of the elastic bands of the back waist section 20 And the front waist section 30 in the side direction. by specifying more in the flat state; the posterior waist section Js 0 is stretched the lateral dimension of the posterior waist section 20 becomes equal or close to the lateral dimension of the perch of the posterior waist section 20 by itself; The anterior waist section 0 is stretched until the lateral dimension of the anterior waist section 30 is equal to or close to the lateral dimension of the perch member.

For front waist section 30 on its own.

0 The absorbent main body 10 is an organ placed against the wearer's crotch to absorb waste such as urine. As shown in Figure 3, the main absorbent body includes 10 upper sheets, 11 top sheets equipped on the skin side, and 13 back sheet Lila sheets equipped on the non-skin side, 0 without absorbent core. 12 is fitted between the top tray 11 and the back tray 13; And an external chick Bene 14 sheet closer to the side of the non-skin das to the back chick 13. As shown in Fig.

5 2 for the main absorbent body 10 also side sheets 15 placed in each of the lateral sides. The upper tray 11 is a fluid permeable insert member Jie nonwoven fabric and the back tray 13 is an impermeable insert member such as polyethylene or polypropylene ©001701007160. The absorbent core 12 is formed by forming liquid absorbent layers

“all Jie absorbent materials 0 pulp pulp fibers or super- absorbent polymer Note 43) The absorbent core 12 can be covered with what is called Qllll Calas as a member FA permeable to liquids such as non-woven fabric or canvas. The outer chick 14 is a soft chick organ like non-woven fabric. 15 leak-proof sheet members are obtained

25 on it using treatment; For example (JU) for non-woven fabrics or the like. As shown in Figure 2, stretchable/contractable 151 elastic members are provided in

Longitudinal direction of the sucking main body 10 at the lateral outer ends of the lateral embryonic 15. As a result; Each of the parts of the lateral sides of the absorbent main body 10 act as what are called (LG) leg gathers lad) to accommodate the wearer's legs. For example, an elastic string or an elastic sheet can be used as the elastic member 151. Note that it is laid out in Figure 2 for the elastic member 151 with the undotted chain lines. In the meantime; The lateral inner ends of the lateral flaps 15 are folded outward in the lateral direction; In order for the folded parts to be equipped with (not visible) stretchable/contractable members along the longitudinal direction of the absorbent main body 10. As a result; The lateral inner ends of the side panels 15 act as a so-called barrier cuff Jalal Jf 0 LSG qualified to align with the skin side to prevent leakage of waste. As shown in Figure 2; the rear waist section 20 has a rectangular shape with Long side in lateral direction as seen in overhead view.As shown in USE 3; for the rear waist section 20 inner sheet sheet 21 fitted on the leather side; outer-layer sheet 22 fitted on the non-leather side And a large number of stretchable members 23, subject to contraction in the lateral direction. Between the inner-layer-bracket 21 and the outer-layer-bracket 22 and is attached to the inner-layer-bracket 21 and the outer-layer-bracket 22 while being stretched in the lateral direction.According to an embodiment of the present disclosure, a large number of elastic strings of 23 are used.With That; without being limited to a large number of elastic strings; for example; can also be used polyurethane elastic fibers in the form of a chain; 43a sheet-like elastic members or similar. Note that the abundance of plastic members 23 is indicated by the dotted lines in Figures 1 and 2. 5 As shown in Figure 2, the plastic members 23 fitted vertically above the absorbent core 2 are equipped continuously from one end to the other in the lateral direction. Members overlap

The plastic 23 with the absorbent core 12 with discontinuous parts on the absorbent core 2. With this cola) Since the plastic members 23 have discontinuous parts on the absorbent core 12; It is possible to restrain the absorbent core 12 of the back side from contracting excessively in the lateral direction and to allow the absorbent core 12 to lean tightly against the wearer's back without a gap, thus suppressing excreta leakage. As shown in Fig. 2 for the front waist section 30 a rectangular shape with a long side in the lateral direction as seen in the above view. As shown in Figure 3 front waist section 0 inner layer sheet 31 fitted on the leather side; outer-layer chick 32 equipped on no-skin Gila; And many members of 33 elastic bands are stretchable/contractable in the lateral direction. layer chick

0 inner 31 and outer layer chick 32 are two chick organs like non-woven fabrics. According to an embodiment of the present disclosure; For the front waist section 30 folded part 320 formed by folding down the upper vertical end gall of the outer layer sheet 32. As shown in Figure 3; The folded part 0 is prepared on the skin side of the inner layer sheet 31 and on the non-skin side of the absorbent main body 0 in the direction of thickness. This folded ial 320 will be described later in detail.

5 As shown in Figures 1 and 2; For the front waist section 30 a cut-out part 40 is formed by cutting a lateral central portion of the vertical upper end portion 34a down from the upper end 301 in an arc. Thus all upper end 34a" denotes an area extending from the lower end 402 all of the cut 40 to the upper end 301 of the front waist section 30 in the vertical direction of the front waist section 30. Note that, although the cut off part 40 has the shape of an arc projecting downwards In the embodiment of detection

0 current; It can have other shapes, Jie, rectangular shape without being limited to the shape of the bow. in that case; Since the cut part 40 is formed by straight lines; (Kad simplified design work. For example; ial) the cut could be 40 straight slits of a predetermined length in the vertical direction. in that case; It can facilitate manufacturing and prevent the generation of discarding of the cut part during manufacturing. in Figure 3; Portions of the inner layer chick 31 and the outer layer chick 32 (incl

5 folded part 320) cut by cut part 40 with dotted lines.

in this way; La gal front waist 30 gal cut 40; A newborn's Jalal wetted navel can be avoided by a clip or a clip worn by a newborn child on his/her navel to prevent bleeding. Injury to the front waist section 30. Bla) Therefore. It is also possible to avoid that event which worries the one who puts the nappy 1 at the time (the mother or the like) that the nappy 1 comes into contact with the navel; Etc; And that the nappy 1 is pulled up insufficiently, which leads to leakage of droppings. According to an embodiment of the present disclosure; As shown in Figures 1 and V2 the back waist section has 20 segments cut out. however; The cut-off part can also be fitted in the back waist section 20. Many elastic members 33 are prepared side by side, spaced from each other in the vertical direction 0 between the inner layer sheet 31 and the outer layer sheet 32 and fixed to the inner layer sheet 31 and the outer layer sheet 32 while It is stretched in the lateral direction. According to an embodiment of the present disclosure; Many spandex chains are used as spandex 33. With (ell) as with the spandex 23 other materials can also be used for spandex alll 33 instead of spandex chains. For example (Jia) Polyurethane spandex may also be used in the form of a 5-chain;semi-strand spandex or the like.Note that many spandex 33 members are indicated by dotted lines in Figures 1 and 2. As shown in Figure 2, the fitted spandex 33 is stretched Vertically higher than the absorbent core 12 and lower than the lower end 402 ALL cut 40 continuously from one end to the other in the lateral direction. 33 gia is not continuous on the absorbent core 2. It can prevent the absorbent core 12 from excessively contracting in the lateral direction on the front side and bring the absorbent core 12 in close contact with the front of the wearer without a gap. each of the lateral sides hall cut 40 and above the bottom end 402 gall 5 cut 40 in the vertical direction; The elastic member 33 is fitted continuously from edge 1 of the cut section 40 to each of the side end sections 300 of the front waist section 30.

<320 shall all>

Then the pleated Gall Chia 320 front waist section 30 detailing will be done based on

Figures 4 to zh

Figures 4 to 4c are illustrative diagrams describing the front waist section 30. Fig. 4 is an illustrative top view showing the circumferences of the front waist section 30 in unfolded dla

and mouted. Figure 4b is a cross sectional view taken along line 4b-4b of Figure 4a.

Figure 4c is a cross sectional view taken along line 4c-4c of Figure 4a. Notice it

Indicated in figure ed is the shal of the inner-layer 31 and the outer-layer 32 (including

That folded gall 320) cut shall cut 40 with dotted lines.

0 as shown in Figures 4b and zd Since the front waist section 30 is equipped with the folded part 320, the front waist section 30 has a section 35 in which the number of layers is greater than that of the lower end section 34b. In the description (JU) a gall 35 in which the number of layers is greater than the number in the lower end portions 34b will be referred to as 'on' overlapping portion 35'. Specifically; the number of layers in gall intervening 35; while

5 The number of layers in the lower end gall 34b andl the front waist 30 two” so that the number of layers in the overlapping gall 35 is greater than the number in the lower end gall 34b. In this intersected hall 35; The number of layers increases due to the folded gall 320. i.e. (of) the number of layers increases as much as the upper end gall of the outer layer sheet 32 can be folded downward. As a result, the stiffness of the overlapping gall 35 is greater than the stiffness of the lower end parts 34b for the waist section

0 anterior 30. HANA “hardness” denotes the lack of deformability in response to an external force acting on the anterior waist section 0. as the stiffness value to compare the level of stiffness; For example; A dad can be used obtained by dividing the dad measurement based on the Gourley flexural resistance by the length of a sample. Gourley flexural strength can be measured based on JIS-L1096 standard using a Gourley type hardness tester.

in this manner »; Since the overlapping part 335 is formed by the folded part 320; It is not necessary to supply a separate spawn member to increase the number of layers in the overlapping gill 35. Thus the number of members forming the front waist section 30 can be reduced. Nevertheless; The nested part 35 need not be fitted with the folded part 320. It is a case in which the nested gall is formed by equipping other types of sheet members which will be described hereafter in connection with a second embodiment. According to an embodiment of the present disclosure; As shown in Figures 4a and 4b; The lower end 352 staggered gall 35 is placed vertically lower than the upper end 101 of the sucking main body 10 and higher than the upper end 121 of the sucking core 12. Thus the lower end 352 staggered gall 35 is placed at least vertically lower than the lower end 402 all Lot 40. Way 0 to embody the current detection; As shown in Figure 4c; The upper end 311 of the inner layer flap 31 is placed vertically lower than the upper end 301 of the anterior waist section 30. So (und) the same as in the lower end section 34b; The number of layers is two in gin from the upper end 311 of the inner layer sheet 31 to the upper end 301 of the front waist section 30 in the vertical direction. It corresponds to the overlapping gall 35 where the number of layers is three part from the lower end 322 all 5 folded 320 to the upper end 311 of the inner layer sheet 31 in the vertical direction. In other words; The position in the vertical direction of the lower end 352 of the overlapping part 35 is the same as that of the lower end 322 of the folded gall 320; The position in the vertical direction of the upper end 1 of the staggered part 35 is the same as that of the upper end 311 of the inner layer sheet 31. Thus the upper end 351 of the staggered part 35 is placed vertically lower than the upper end 301 of the anterior 0 waist section 30. In this way; le It is not equipped with the overlapping gall 35 in the upper end gall of the front waist section 30 (part positioned vertically higher than the upper end 311 of the front waist section 31); The stiffness of the front waist section 30 in the vicinity of the THB waist opening (see Fig. 1) is lower (softer) than that of the overlapping gall 35. Thus; The weave can be improved when wearing nappy 1.5 according to an embodiment of the present disclosure; As shown in Fig. 4, the overlapping gal) 35 extends from edge 1 of the cut segment 40 to one of the end segments 1300 and the other end segment 300b (both

The two end parts 300) of the front waist section 30 in ein placed vertically higher than the lower end 402 gall cut 40. Thus a pair of spandex members 33 fitted on either side of the gall cut 40 of the front waist section 30 and vertically up from Lower end 2 of cut off part 40 in overlapping gall 35.

on the lower side of the lower end 402 of the cut off part 40 in the vertical direction; The overlapping part 35 extends continuously from one of the end parts 1300 to the other end part 300b in the lateral direction of the front waist part 30. Thus a multitude of spandex members 33 are fitted vertically below the lower end 402 cut gall 40 in the overlapping gall 35 in Figure 4a; The range of overlapping part 35 is indicated in bold. in this way; According to an embodiment of the present disclosure;

0 The overlapping gall 35 extends from one of the lateral end parts 1300 to the other lateral end part 0b of the front waist section 30 with the exception of the cut part 40. The stiffness thus increases in the lateral direction. Note that; in lower end gall 34b of front waist section 30; The number of layers shall be two; In order for its stiffness to be less than that of the overlapping gall 35. Whereas the lower terminal gall 34b

5 close to the legs of the ad) the lower end gall 34b is smoothed into the wearer's legs. Thus the discomfort of wearing can be reduced by setting the stiffness of the lower end part 34b to be less than that of the overlapping part 35. Diaper manufacturing method 1> Next; The manufacturing method for Diaper 1 will be described based on Figures 5 and 6.

0 Figure 5 is a diagram showing the manufacturing process of Diaper 1. Figure 6 is a diagram showing the process of folding 52 in the manufacturing process of Diaper 1. As shown in Figure 5; The manufacturing method of the diaper 1 ay to embody the present discovery includes the process of forming the ST pad (a process 52; joining process 56; and cutting process 57). In the process of forming the “ST” waist section while a large number of spandex members are prepared 23 and 33 along the direction

5 Transition between Inner Layer Layer Member 01 Ly incl Inner Layer Layer 21 of the Rear Waist Section 0 and Inner Layer Layer 31 of the Front Waist Section 30 and Outer Layer Layer Member P2 incl.

That outer layer bracket 22 of the posterior waist section 20 and outer layer bracket of the anterior waist section 30, these organs are transferred (inner layer bracket 01 outer layer bracket member 2; and a large number of spandex members 23 and 33). in that case; A profusion of plastic members 23 and 33 are transported in the direction of transport in the flat state. Cutout portions 1© and 2© are machined to separate the inner layer member Pl and the outer layer member P2 at the rear waist section side 20 and the front waist section side into central portions in the transverse direction ( perpendicular to the direction of transport) of the two chick organs; respectively. Sectioned portions 1© and C2 are formed so that the gall layers truncated 1© of the inner shell member 01 and the truncated portion 2© of the outer layer member 02 are formed so that the 0 align with each other. in this way; In the process of forming the 581st waist section; The matching parts of the back waist section 20 and the front waist section 30 of the diaper 1. are formed in Figures 5 and 6; The directions of organ transport are indicated by arrows al d (MD) and indicated in a direction perpendicular to the direction (orthogonal direction) of transport by bidirectional arrows CD 0©. In the following description, the direction of transport will be indicated as the 'direction' CMD and 5 orthogonal direction will be referred to as the “JCD direction” in the folding process all 52; as shown in Figure 6; with the inner layer member 01 and the outer layer member P2 layered together passing some through Sa nipping portion 7 folds inward oi terminal outer in direction CD corresponds to front waist section 30. As a result, as shown enlarged in Fig. 5 forming sia corresponding to folded portion e325 320 0 corresponds to the overlapping gall 35. Thus, as shown enlarged in Fig. 5; in the process of shaping the waist section 51 dae] length in the direction CD corresponds to the front waist section 30,; lila is longer than the length in the direction CD corresponds to the posterior waist section 20. In the transfer process Ja the absorbent main body 53; a transfer is made so that the absorbent main body 10 is internally supplied with the absorbent core 12 flattened between the sucking side Corresponding to the rear waist section 5 20 and the side corresponding to the front waist section 30 spaced apart in the direction

CD with the cut parts 1© and 62 as shown in Figure 5. In that case; An operation is being performed

Transfer so that the longitudinal direction of the absorbent main body 10 aligns with direction 00.

in the process of forming all lump 54; The inner layer member PI and the layer member are cut off

The outer P2 arches inwards from the outer edge in the direction CD on the side corresponding to the front waist section 30. As a result; The cut gal) forms 40 (see Figs. 1 and 2). in this

case; The cut off part 40 is shaped so that the lower end 402 gallon cut 40 is positioned lower

From the upper end 351 of the overlapping part 35 formed in the process of all 52 (see fig. 4a and 4c).

In the manufacturing process of diaper 1, the cut part 40 is formed after the overlapping part 35 is formed

Rigidity in the process of folding 52 with this method.

0 In the ¢S5 layering process, the side corresponding to the front waist section 0 is folded into contact with the side corresponding to the rear waist section 20 to match the MD layering position fitted in the longitudinal central portion. for the main absorbent body 10. As a result; The absorbent main body 10 is folded in half. In the joining coin 86 the corresponding parts of each of the lateral end parts 200 of the waist section are joined

5 rear 20 and matching parts of each of the side end parts 300 of the front waist section 30 in succession to each other »for example »by thermal welding or cultrasonic welding in case the side corresponding to the rear waist section is pulled 20 and the side corresponding to the front waist section 30 along direction MD with the result; Parts corresponding to a pair are formed from 100 joined parts (see Figure 1).

0 in the cutting process 57”; The parts corresponding to the pair of joined parts 100 formed in the joining process 56 are cut along a cutting line in the direction LCD with the result; Diaper 1 is produced in a layered state according to an embodiment of the present discovery; The manufacturing process proceeds in order to form the waist section 51; Folding process 52) Absorbent main body transportation process 53; Cut-off forming process 54 process

5 create layers 55; annexation 56; and cutting process 57. However; Not only this sequence of process but; For example; The process of transferring the absorbent main body 53 can follow

truncated gall formation process 54. In that case; The main absorbent body 10 is necessarily set up not to overlap with the cut-gall region 40. The manufacturing process of the diaper 1 can not be restricted as long as at least the cut-gall-forming (gia-cut-forming process 54) follows the folding process 52 and follows the process of mall 56 The process of shaping the cut part 40. Viz; as an operation to increase the number of layers in the upper end portion 134 of the front waist section 30; A first process refers to the process of forming a gall corresponding to folded gall 320; The second process refers to a process for forming truncated gall 40; The third operation refers to a process to join a part corresponding to each of the side end parts 200 of the rear waist section 20 shag corresponding to each of the side end parts 300 of the front waist section 30 respectively. in that case; shal 0 enables at least the first to third processes in this sequence. after that; Differences between Pad 1 according to an embodiment of the present disclosure and Pad 1a according to a comparative Jad based on Figures 4a to 4c and NT 7c will be described. Figures 7a to 7c are schematic diagrams showing the TT diaper for a comparative example. Figure 7a is an illustrative overhead view showing the dlls of the side of the front waist section 30a during manufacture. Figure 7b5 is a cross sectional view showing the anterior waist section BO of diaper 1a. Figure 7c is an illustrative overhead view showing the condition of the joining part 1100. Note that; In Figures 7a to 7c for simplicity; Not many plastic organs are shown 33. As shown in Figure 7b; The front waist section BO of diaper 1 of the comparative example does not have a pleated gall other than the front waist section 30 of diaper 1 in the embodiment of the present disclosure. meaning 0 it is; The upper end of the outer layer chick 32 is folded down. and so on, as shown in Figure 7b; The number of layers in the BO front waist section is set to two across an area from vertical bottom end 302 to top end 301; The roughness and the front waist BO Jal is that of the overlapping gall 35 of the front waist section 30 in the nappy 1 notch embodying the present detection across the area of the front waist section 30a. 5 in that case; in the process of annexation 56 (see Figure 5); If a part corresponding to each of the side end parts 200 is joined to the rear waist section 20 and a part corresponding to each of the side end parts

0 of the front waist section 30 to each other in a situation where the side corresponding to the front waist section 30a is pulled in the lateral direction (in the direction along the direction (MD) as shown in Figure 7) the upper end section 34a is joined discontinuously (gall) Section 40 is in a state in which it curls downward (toward the absorbent main body 10). As shown in Figure 7c, deflection may occur in a pair of compact fragments 1100a. Note that Fig. 7c shows a case in which deflection occurs only in one of the pair of compact fragments 1100 at However, in nappy 1 Gy of an embodiment of the present disclosure, wherein the front waist section 30 has the overlapping part 35 three layered on the vertically higher side of the lower end 402 Hall cut 40 as described above (see fig. 4b and 4c); the hardness of the overlapping gall 35 becomes 0 higher than the hardness of the upper terminal part 34 anil the anterior waist 30 according to the comparative example. of the rear waist section 20 and the corresponding part of each of the lateral end sections 300 of the front waist section 0 to each other if m in which the side corresponding to the front waist section 30 is pulled in the lateral direction (in a direction along the direction (MD), meaning that it is; The multitude of 33 elastic members is stretched; 5 The upper terminal part 34a is less likely to wrinkle downward; Thus, it is possible to prevent professionalization in a pair of compact parts 100. In the manufacturing method of the diaper 1; The cut gall 40 is formed in the cut-out process 54 in the case that the number of layers of the upper end part 34 of the front waist section 30 in the fold process 52 is increased (to form the part corresponding to the folded part 320) to increase the stiffness; Then the process proceeds to 0 join 56. Thus, the part corresponding to the upper end portion 34 of the anterior waist section 30 is less likely to wrinkle in join 586; Thus the Mage to prevent deviation in the pair of joined parts is 100. According to an embodiment of the present disclosure; Since the lower part 352 intervening gall 35 is placed vertically lower than the ends (aud) 402 of the cut portion 40 and more vertically lower than the upper end 101 of the main absorbent body 5 10 as previously described (see Figs. 4a to 4c); The overlapping part 35 is processed across a wider area in the vertical direction. and then; ea has high increases in

callousness for this canal even when work is made to join each of the lateral end-parts 200 of the rear waist-section 20 and each of the lateral-end-parts 300 of the front waist-section 30 respectively to each other in a situation where the front waist-section 30 is drawn in the lateral direction; The upper end part 34 is less likely to wrinkle downward.

According to an embodiment of the present disclosure; The overlapping galll 35 is fitted across an area from the edge 401 of the cut-out section 40 to each of the lateral end-parts 300 of the front waist section 30 at least on the vertically higher side of the lower end 402 of the cut-out section 40 (see Fig. 4A); As we described before; Hence the stiffness increases across the entire region in the lateral direction on each of the lateral sides of the cut part 40. Note that the overlapping part 35 is not necessarily processed through the region

0 from edge 401 to each of the side end parts 300 of the front waist section 30. Alternatively the overlapping part 35 can be fitted into part of each of the side skirt areas gyal cut

In addition to that; Since the 33 rigidity plastic members are processed; on each side of the cut ial 40; above the lower end 402 gallon cut 40 in the vertical direction and 5 interlocked with the overlapping gall 35 (see Fig. 4a); Stiffness is increased in the upper end portion B4 of the anterior waist section 30. Thus the upper end portion 34 is less likely to wrinkle downwards (Lila) even when both lateral end portions 200 of the posterior waist section 20 and each of the lateral end portions 300 of the posterior waist section 20 are combined Front waist 30 in dlls in which the front waist section 30 is pulled in the lateral direction. Note that the elastic members 33 do not have to intersect with the intervening gall 0 35. First modification Next the configuration of a first modification Tg 1b will be described based on Figures 8a to 8c. Figures 18 to 8c are schematic diagrams showing the front waist section 30b of diaper Gl according to the first modification. Fig. 18 is an illustrative overhead view showing enclosures of the anterior waist section 5 30b in an unfolded and flat state. Figure 8b is a cross sectional view taken along line 8-8 of Fig. 8) and Figure 8c is a cross sectional view taken along line Joh

28-28 of Figure 8a. in Figures 8a to 8c; Items similar to those in Nappy 1 are given

From the first embodiment the same reference numbers and ignoring their description. The same goes for the Second Amendment

(Figs. 9a to 9c) and the second incarnation (Figs. 710 to 10c and Fig. 11).

In nap 1b according to this modification” the vertical length of the nested gall 35b is shorter than the vertical length of the nap 35 of nap 1 in the first embodiment. Meaning oof the amount of folding the part

The upper end of the outer layer flap 32 of the anterior waist section 30b is smaller than that of

For diaper 1 dg for the first embodiment and the vertical length of the folded part 320b is shorter than the length

The vertical of the folded part 320 in nappy 1 according to the first embodiment.

specifically; As shown in Figure 8a; The lower end 352 of the overlapping part 35b is positioned higher

0 vertically from the lower end 402 , cut gall 40. Hence; The overlapping gall 35b is not fitted vertically lower than the lower end 402 all cut 40 as shown in Figure 8b; However the overlapping gall 35b is fitted to extend laterally each side of the cut gall 40 as shown in Figures 18 and 8c. Note ca) in Fig. 8a; A range corresponding to overlapping gall 35b is indicated in bold.

5 even then; The overlapping galll 35b of higher stiffness than that of the lower end section 34b is fitted above the lower end 402 of the cut section 40 in the vertical direction of the front waist section 30b. And so on even when each of the lateral end sections 200 of the rear waist section 20 and each of the lateral end sections 300 of the front waist section 30b are joined respectively to each other” in a case where the front waist section 30b is pulled in the direction

0 lateral (in the direction along the direction (MD) in the sense of “a condition in which a large number of members of the elastic band 33 are spread out, the upper end part B34 is less curled downward; this qualifies to prevent deflection in a pair of joined parts 10. And so on unlike diaper 1 in the first embodiment The bottom end 352 of the overlapping part need not be placed vertically lower than the bottom end 402 of the cut gall 40. Alternatively, the part can be fitted

5 overlapped 35 at least vertically higher than the lower end £21402 cut off 40. Second Amendment

after that; The composition of diaper 1c will be described according to a second modification based on Figures 9a through and c. Figures 19 to 9c are schematic diagrams showing front waist section 30c of nappy 1c according to the Second Amendment. Fig. 19 is an illustrative overhead view showing enclosures of the anterior waist section 0h in an unfolded and flat state. Figure 9b is a cross sectional view taken along line 9b-9b of Fig. 9a. Fig. 9c is a cross sectional view taken with line length 29729 of Fig. Jo in nappy 1c according to this modification; the vertical length of the overlapping part 35c is longer than the vertical length of the overlapping part 35 of nappy 1 according to the first embodiment. Specifically, the amount of fold of the upper terminal part of the outer layer chick 32 in the anterior waist section 30c is greater than that of 0 nappy 1 of the first embodiment; The vertical length of the folded part 320 g is longer than the vertical length of the folded part 320 in nappy 1 according to the first embodiment. Accordingly; As shown in Figure 9a; The lower end 352 gall overlapping 35g is placed vertically lower than the upper end 121 of the absorbent core 12 of the main sucker body 10) and the overlapping part 35g is overlapped with the absorbent core 12 in the direction of thickness as shown in Fig. 9b. However; 5 as shown In Fig. 9a, the overlapping galll 35c is not fitted into the lower end gall 34b of the front waist section 30c, and two layers are formed in the lower end section 34b in accordance with this modification.In that case, since the overlapping galll 35 extends upwards to a position where the overlapping gall 5h overlaps the absorbent lll 12 of thickness; oda increases a higher stiffness more in the vertical direction. Thus 0 even when both the lateral end-parts 200 of the rear waist section 20 and each of the lateral end-parts 20 are joined 300 for the front waist section 30c in succession to each other; in Als in which the front waist section 30c is pulled in the lateral direction (in a direction along the direction “MD” meaning; Alls in which a large number of members of Lal 33 are stretched The crease of the upper end part 34 is reduced to the bottom, and thus qualifies for additional skew prevention in a pair of joined parts 100. 5 Second embodiment

5 first. dass after the process of shaping the waist section 81 (see Figure 5); A nest member (separate nest 36) different from the inner layer lay member P1 and the outer layer lay member P2 is inserted with an outer terminal eye in the direction CD of the side corresponding to the front waist section 30d in the interpenetration process 0 as shown In Figure 11. With the result; The overlapping gall 35d is formed with more layers than that of the lower terminal gall 34b.

0 with this skal) the overlapping galll 35d is formed by placing a separate sheet 36 different from the inner layer sheet 31 and the outer layer sheet 32 forming the lower end part 34b of the front waist section 0d at least on the higher side of the lower end 402 cut gall 40 in the vertical direction. Accordingly; The nappy al can be manufactured by eliminating, for example, the need for an interlocking process; Compared to a case where the overlapping part 35 is formed by folding the upper terminal part of the outer layer sheet

5 32 as in diaper 1 for the first embodiment.

According to an embodiment of the present disclosure; A separate sheet 36 is fitted on the skin side of the intra-layer sheet 31 in the direction of thickness and on the non-skin side of the absorbent main body 10 as shown in Figure 10b. It is not limited to that; For example, a separate sheet 6 can be equipped on the skin side of the absorbent main body 10 to cover part of the other terminal side 10b of the absorbent main body 10. In this lal it is also possible to prevent discomfort that may occur when worn by reducing the difference in thickness. Between the absorbent main body 10 and the front waist section 30 d.
