A composite sheet comprising an upper layerand a lower layerboth made of a substantially inextensible sheet which are partially bonded to each other at a large number of joints. The upper layerforms a large number of outward hollow projectionsin the area other than the joints. The projectionsand the jointsare arranged such that the projections and the joints alternate in one direction to make lines and that the projections in each of the lines are out of alignment with the projections in the adjacent lines.

Composite sheet and process and apparatus for producing the same

A method for manufacturing an absorbent article comprising the steps of continuously feeding out a long, extensible, continuous member ( ) from a predetermined position, cutting the continuous member ( ) into lengths (P ) each equivalent to a length of one sheet of the absorbent article at a predetermined position, and fixedly arranging the cut continuous member at a predetermined position of the absorbent article, wherein a predetermined pattern is preliminarily printed on the continuous member ( ) at a printing pitch shorter than the cutting length (P ) of the continuous member, and the speed for feeding out is controlled such that the predetermined pattern is located at a predetermined part of the cut continuous member, thereby obtaining the absorbent article in which the predetermined pattern is arranged at a predetermined position.

Production method for absorbent article

A disposable wearing article including a liquid-permeable topsheet, an outermost layer sheet located on an outer surface of the disposable wearing article, and a liquid retentive absorbent member, a waist-surrounding elastic member being arranged at a waist-surrounding portion, wherein the waist-surrounding elastic member is fixed to other members than the outermost layer sheet in an expanded state to thereby form gathers inwardly of the outermost layer sheet, a non-bonding area is provided between the waist-surrounding elastic member and the outermost layer sheet, and no gathers are formed on an outer surface of the waist-surrounding portion.

Disposable wearing article

A shorts type disposable diaper includes an absorptive body having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorber interposed between the topsheet and the backsheet. The absorptive body is divided into a stomach side portion, an under-crotch portion, and a back side portion, substantially continuous elastically expansible members being disposed over entire peripheral edge portions of a waist opening and a pair of leg openings which are formed by fixedly connecting confronting opposite side portions between the stomach side portion and the back side portion. The absorber is 8 mm or less in thickness and 100 mm or more in width in the under-crotch portion, and the distance from a side edge of the under-crotch portion of the absorber to the elastically expansible members disposed in the leg opening is 15 mm or more.

Shorts type disposable diaper

A tape cassette comprising a slider slidably covering a lower half of a cassette main body containing a magnetic tape, a lock element of the slider withdrawably inserted into the lower half surface, a locking coil spring for pressing the lock element, and a retainer portion for retaining the locking coil spring to an upper half, wherein:
