The present invention provides a method of preparing an absorbent layer from an absorbent nonwoven web having a first plurality of slits with a first orientation and a second plurality of slits with a second orientation, wherein the first orientation is different from the second orientation. The first plurality of slits and the second plurality of slits are at least partially through the absorbent nonwoven web, and the second plurality of slits at least partially intersects the first plurality to form apertures in the absorbent nonwoven web.

Extensible absorbent layer and absorbent article

An absorbent article, such as a sanitary napkin or an incontinence diaper, has an absorbent body having at least one fold line formed therein defining at least two segments of the absorbent body. The segments formed by the at least one fold line are generally foldable relative to each other along the at least one fold line to facilitate conformance of the absorbent article to the wearer's body. In a method of forming the absorbent body, a first cut-out from a first web material is passed through a nip along with a second web material whereby the cut-out from the first web material overlays the second web material. A fold line is then formed in the second web material at the peripheral edge of the cut-out of the first web material as the cut-out and second web material pass through the nip.

Absorbent body for an absorbent product and methods of producing an absorbent body

Apparatus for continuously producing a web ( ) which is corrugated from a thin sheet material which is elastic at least in a transverse direction of the web. The apparatus includes a guide bed ( ) which has grooves extending parallel or inclined to each other in the direction of movement of the material. The apparatus also has holding-down devices ( ) arranged opposite the grooves of the guide bed ( ) so as to urge the web passing between the surface of the guide bed ( ) and the holding-down devices ( ) into the grooves of the guide bed ( ) to obtain corrugations in the web. Finally, at the outlet end ( ) of the guide bed ( ) is an apparatus or substance which substantially prevents the formed corrugations from springing back to the original condition. A process for producing a strip and an absorbent article containing corrugated strips are included.
