The present cuff manufacturing method includes: a step of sandwiching at least two continuous elastic members F between a first sheet and a second sheet; a step of thermally-bonding together the first sheet and the second sheet intermittently in the longitudinal direction to form thermally-bonded portions, thereby fixing the continuous elastic members, thus forming a laminate; a slit step of slitting the laminate along the longitudinal direction, thereby obtaining a pair of cuff members; a step of conveying the pair of cuff members so that a pair of edges, which have been produced by the slitting in the pair of cuff members, are spaced apart from each other; and a step of arranging the pair of cuff members on opposite edge portions of a crotch portion of a worn article, thereby forming cuffs.

A method and apparatus for mechanically deforming a substrate assembly. The substrate assembly may be advanced in a machine direction at a first velocity toward a bonder apparatus. The bonder apparatus may rotate about an axis of rotation and include a support surface between each of a first and a second member. The first member and the second member may be separated by a repitch angle. The second member may be repositioned such that the first member and the second member are separated by a product angle. The first member may receive a leading portion and second member may receive a trailing portion of the substrate assembly and each member may rotate at the first velocity. The leading portion and the trailing portion are separated by a product arc length, which may be equal to a process product pitch. The substrate assembly may then undergo one or more processes such as bonding, cutting, and/or scoring.

The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.

The absorbent article as disclosed herein has longitudinal side edges extending in a longitudinal direction and transverse front and rear end edges extending in a transverse direction. The absorbent article comprises a fluid permeable surface layer, a backsheet and an intermediate layer located between the fluid permeable surface layer and the backsheet. The surface layer has a wearer-facing portion facing the user during use. The surface layer is an air through bonded fibrous nonwoven surface layer having a basis weight of from 14 to 30 g/m2 and a density of from 20 to 90 kg/m3. The intermediate layer extends under from 70 to 100% of the wearer-facing portion of the surface layer. The intermediate layer and the surface layer have a respective elongation at 10 N/50 mm. The elongation of the intermediate layer is lower than the elongation of the surface layer.

A taped absorbent article 20 comprising a crotch channel 26 having a crotch channel bond strength, and a front channel 56 having no bond or a front channel bond strength which is weaker than the crotch channel bond strength. The front channel is at least partially superposed with the landing zone 44 on which the back ear tapes 42 can be releasably fastened. During use, the front channel can delaminate to relieve stress on the landing zone and avoid accidental detachment of the tapes 42.

[Problem] To prevent separation and accompanying tearing of a front-surface sheet when non-heat-fusible fibers are used in the front-surface sheet.

[Solution] An absorber 4 is interposed between a front-surface sheet 3 and a back-surface sheet 2, and side sheets 7 are disposed on both side portions along the longitudinal direction. The front-surface sheet 3 contains non-heat-fusible fibers, and the side sheets 7 contain a heat-fusible resin. The front-surface sheet 3 is interposed between the laminated side sheets 7 on the outer side in the width direction than the absorber 4 whereby a side flap portion SF in which the side sheet 7, the front-surface sheet 3, the side sheet 7, and the back-surface sheet 2 are laminated in that order from the skin side is formed. A fusing portion 10 in which the sheets forming the side flap portion SF are integrally heat-fused is provided in a region of the side flap portion SF including at least the front and back ends of a sanitary napkin 1.

Problem

To suppress skin touch feeling from being deteriorated and further provide excellent wearing feeling, while ensuring sufficient adhesive strength in an adhesion part of a side sheet.

Solution

In the present invention, a pair of left and right side sheets 7 are provided over the entire length of both side parts on a skin-contact surface. A sanitary napkin 1 includes overlapped regions T where a front-surface sheet 3 and the side sheets 7 are overlapped with each other, on the both side parts of the sanitary napkin 1 along the longitudinal direction. In each of the overlapped regions T, a side-sheet embossed part 10 is formed on the side sheet 7, and an inter-sheet embossed part 9 is formed to make the side sheet 7 and the front-surface sheet 3 adhere to each other. The total area of the side sheet embossed part 10 is formed smaller than the total area of the inter-sheet embossed part 9.

An absorbent article includes: a first sheet-like member; a second sheet-like member; an elastic member that is inserted along a lateral direction between a pair of mutually-opposing facing surfaces of the first sheet-like member; joining portions that join the pair of mutually-opposing facing surfaces and that are spaced apart in the lateral direction; and side-seal sections that are disposed at each lateral end portion of the absorbent article. The joining portions are disposed on two sides of the elastic member in a vertical direction, which intersects the lateral direction and a front-rear direction, so that the elastic member is sandwiched and pressed between the joining portions.

A reusable undergarment is disclosed with a multi-layer gusset assembly that is permanently affixed in the undergarment to absorb liquids excreted by a wearer of the undergarment and is reusable after washing. The panty also includes body fabric, elastic trim, and non-wicking hydrophobic thread that is sewn through the trim, which sandwiches the body fabric and gusset assembly. The trim may be a single piece of fabric with a waterproof finish that is folded widthwise to form a hollow channel that redistributes excess liquid at the edge of the gusset assembly without leaking. In some manufacturing processes, a waterproof finish may be applied to the elastic trim, and the edge of the gusset assembly may be positioned offset from a fold-line of the trim when folded widthwise. The shape and positioning of the gusset assembly may be cone-shaped in some embodiments.
