A method for manufacturing a composite sheet includes a first step of, in a state that a curved part of a first sheet whose one surface rises and whose another surface is recessed and that a second sheet is overlaid on the first sheet, revolving a first roller to convey the first sheet and the second sheet; a second step of passing the sheets between the first roller and a second roller revolving so that a pressing part protruding outward in the radial direction from the outer peripheral surface of the second roller is inserted into the recess of the first roller; forming, in a region within the second sheet opposing the curved part, a protruding part which is surrounded by a flat part; and a third step of joining a boundary part of the first sheet to the second sheet.

For bonding together two or more plies of cellulose fibers, the plies are fed to a lamination nip between a ply-bonding rotating element and an anvil element. The ply-bonding rotating element has rollers with a cylindrical surface provided with small protuberances co-acting with larger protuberances provided on a cylindrical surface of the anvil rotating element. The plies are bonded, if necessary with the aid of a functional fluid, not containing adhesive, due to the effect of the pressure between the protuberances.

Provided are a composite sheet whose recess-protrusion shape can easily be made crush-resistant in a state that the soft feel against the skin is maintained, and a device and method for manufacturing said composite sheet. A first sheet has a curved part in which one surface thereof rises and the other surface thereof is recessed, and a boundary part adjacent to the curved part. A second sheet is joined to the boundary part of the first sheet so as to cover the other surface of the curved part. A region of the second sheet facing the curved part has a protruding part in which an inside surface on the first sheet side rises so as to approach the curved part and an outside surface on the reverse side thereof is recessed, and a flat part surrounding the periphery of the protruding part.

Disclosed are the cut edges of an absorbent fabric comprising at least 45% and less than about 90% cellulosic or natural fibers, and a fusible component being stabilized by fusing the fusible component with an arrangement of spaced lines or spaced areas extending from the cut edges, and optionally over the entire absorbent fabric.

A non-continuously laminated structure of thermoplastic films comprises thermoplastic films with differing material compositions and differing functional benefits. In particular, one or more embodiments comprise thermoplastic films that are co-extruded separately and then combined together by a post-extrusion bonding process. The differing composition of the various films of the non-continuously laminated structure of thermoplastic films and the post-extrusion bonding process, provide the structures with the functional benefits of the individual films.

Multi-layer bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge. The first and second layers may be non-continuously laminated together in discrete sections to include bonded regions in which the layers are bonded and unbonded regions in which the layers are not bonded. Such a bag may be described as a bag-in-a-bag type configuration in which the inner bag is non-continuously bonded to the outer bag. The inventors have surprisingly found that such configurations of non-continuous bonding provides increased and unexpected strength properties to the multi-layer films and bags.
