A method of manufacturing an absorbent article in which an absorbent body (4) is provided between a liquid permeable topsheet (3) and a backsheet (2), an absorbent body concave portion (20), which is a concave groove or a slit, being formed at a skin-contacting side including a body fluid expelling area (H) along a longitudinal direction of the absorbent body without using compression, and an embossed portion (21) being formed in the absorbent body concave portion (20) along the absorbent body concave portion (20) by embossing from a top surface side of the liquid permeable topsheet. The method includes a first step of forming the absorbent body (4) provided with the absorbent body concave portion (20); a second step of forming core embosses (23) at least on both sides of the absorbent body concave portion (20) by compressing the absorbent body from the skin-contacting side of the absorbent body (4); and a third step of stacking the liquid permeable topsheet (3) on a top surface side of the absorbent body (4) and forming the embossed portion (21).

A method for manufacturing a composite material includes forming a composite precursor material comprising a nonwoven layer comprising a plurality of fibers and a polymer film layer laminated to the nonwoven layer; forming a plurality of apertured extended cells in the polymer film layer, each of the apertured extended cells having a continuous sidewall extending away from the nonwoven layer that terminates in an aperture at a distal end; and, while forming the plurality of apertured extended cells, pushing, with a fluid, at least one of the fibers into at least one of the apertured extended cells so that a portion of the at least one of the fibers extends into the at least one of the apertured extended cells and through the aperture at the distal end.

The present invention relates to a method for fabricating absorbent article having multiple layers, and deformed zones of targeted performance, and colored regions, the method comprising the steps of forming discrete features on at least one layer, printing colored regions on at least one layer, integrating multiple layers to form an absorbent assembly, and cutting the absorbent assembly into individual absorbent articles, wherein the steps are carried out continuously.

A fiber optic cable includes a cable core of core elements and a protective sheath surrounding the core elements, an armor surrounding the cable core, the armor comprising a single overlap portion when the fiber optic cable is viewed in cross-section, and a jacket surrounding the armor, the jacket having at least two longitudinal discontinuities extruded therein. A method of accessing the cable core without the use of ripcords includes removing a portion of the armor in an access section by pulling the armor away from the cable core so that an overlap portion separates around the cable core as it is being pulled past the cable core. A protective sheath protects the core elements as the armor is being pulled around the cable core.

Provided is a process for thermoforming a gas and liquid permeable layer (10) of thermoplastic material having an average thickness of less than 1.0 mm, the process comprising the steps of bringing the layer of thermoplastic material, at a temperature below that required for thermoforming, into contact with a mould (16) at a temperature above that of a thermoforming temperature of the thermoplastic material; pressing the mould into contact with the layer of thermoplastic material, the contact between mould and thermoplastic material causing heat to transfer from the mould to the thermoplastic material and raising the temperature of the thermoplastic material to a thermoformable temperature; such pressing thereby causing thermoforming of the thermoplastic material to conform to the shape of the mould.

A method for manufacturing an absorbent article, the method including: while a lower bandlike member is transported in a transport direction, a process in which a cutting position is determined and an adhesion area is formed on each side of the cutting position of the lower bandlike member in the transport direction; a process in which leg elastic members are placed so that a part of each of the leg elastic members overlaps the adhesion area, the leg elastic members being stretched in a direction having a component parallel to the transport direction; a process in which an upper bandlike member is stacked on and adheres to the lower bandlike member and the leg elastic member on the adhesion area; a process in which the lower bandlike member and the upper bandlike member are folded on the center in the intersecting direction; a process in which a welded section on which the lower bandlike member and the upper bandlike member are to be welded to each other is formed on each side of the cutting position in the transport direction; a process in which and the lower bandlike member, the upper bandlike member and the leg elastic members are cut together on the cutting position, a lower exterior member and an upper exterior member which are shaped in the form of underpants are cut and separated, the leg elastic members which are stretched contract towards the adhesion area from positions at which the leg elastic members are cut, the contraction being performed while the leg elastic members shifting relative to the lower exterior member and the upper exterior member.

A method for manufacturing an absorbent article, the method including: while a lower bandlike member is transported in a transport direction, a process in which a cutting position is determined and an adhesion area is formed by putting adhesive on each side of the cutting position of the lower bandlike member in the transport direction; a process in which elastic members are placed so that a part of each of the elastic members overlaps the adhesion area, the elastic members being stretched in the transport direction; a process in which an upper bandlike member is stacked on and adheres to the lower bandlike member and the elastic member on the adhesion area; a process in which the lower bandlike member and the upper bandlike member are folded on the center in the intersecting direction; a process in which a welded section on which the lower bandlike member and the upper bandlike member are to be welded to each other is formed on each side of the cutting position in the transport direction; a process in which and the lower bandlike member, the upper bandlike member and the elastic members are cut together on the cutting position, a lower exterior member and an upper exterior member which are shaped in the form of underpants are cut and separated, the elastic members which are stretched in the transport direction contract towards the adhesion area from positions at which the elastic members are cut, the contraction being performed while the elastic members shifting relative to the lower exterior member and the upper exterior member.
