  • Publication number: 20130123088
    Abstract: A method of producing an absorbent body includes the steps of passing a first cut-out from a first web material through a nip and passing a second web material through the nip whereby the cut-out from the first web material overlays the second web material as the cut-out and the second web material pass through the nip. One of the following is performed as the cut-out from the first web material and the second material together pass through the nip: forming a fold line in the second web material at the peripheral edge of the cut-out of the first web material and forming a second cut-out from the second web material having substantially the same shape as the first cut-out from the first web material.

  • Patent number: 8387497
    Abstract: 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.

  • Publication number: 20120322639
    Abstract: A method of producing an absorbent body for an absorbent article having an absorbent body disposed generally centrally of the article and adapted for absorbing liquid body waste released by the wearer includes passing a first cut-out from a first web material through a nip, passing a second web material through the nip whereby the cut-out from the first web material overlays the second web material as the cut-out and the second web material pass through the nip, and performing one of the following as the cut-out from the first web material and the second material together pass through the nip: forming a fold line in the second web material at the peripheral edge of the cut-out of the first web material and forming a second cut-out from the second web material having substantially the same shape as the first cut-out from the first web material.

  • Patent number: 8187242
    Abstract: 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.

  • Publication number: 20060047257
    Abstract: The present invention provides an absorbent article, such as a sanitary napkin or catamenial napkin, wherein the absorbent article has a longitudinal direction and a lateral direction, the absorbent article has: a) a liquid-permeable top layer, wherein the top layer has an extensibility in lateral direction of at least 30% to 70% at 4N/50 mm, b) a liquid-impermeable backing layer laminated to the top layer, wherein the backing layer has a higher extensibility in lateral direction than in longitudinal direction and the extensibility in lateral direction is at least between 5% and 40% at 4N/50 mm, and c) an absorbent core positioned between the top layer and the backing layer, wherein the absorbent core has a plurality of non-linear slits and/or linear slits at an acute angle relative to the longitudinal direction through the absorbent core.

  • Patent number: 6548147
    Abstract: Apparatus for continuously producing a web (1) 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 (2) 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 (5) arranged opposite the grooves of the guide bed (2) so as to urge the web passing between the surface of the guide bed (2) and the holding-down devices (5) into the grooves of the guide bed (2) to obtain corrugations in the web. Finally, at the outlet end (4) of the guide bed (2) 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.
