A wound dressing includes an hydrophilic foam layer which is coated with a liquid-permeabe adhesive layer on one side. The dressing includes an absorbent layer disposed on the foam layer on the side opposite to the adhesive coating, wherein absorbent layer is able to drain the foam layer through the action of capillary forces, and wherein the dressing further includes elements that ensure effective contact between the absorbent layer and the foam layer.

Wound dressing

The present invention relates to a wound dressing that includes a carrier layer which is coated on one side with an adhesive elastomer ( ). According to the invention, the carrier layer has the form of a laminate which consists of a plastic film ( ) and a material ( ) that has an irregular surface structure.

An absorbent article (,) such as a sanitary napkin, having an elongate absorbent core (,) delimited by an upper surface (,) and a lower surface (,), a pair of opposed longitudinal edge portions (,) terminating in longitudinal edges (,), and a pair of opposed transverse edges (,). The core has a first end portion (,), a second end portion (,) and a mid portion (,) located between the end portions. The article further includes a liquid permeable topsheet (,) extending over the upper surface (,) and a liquid impermeable sheet (,) covering the longitudinal edge portions (,) of the absorbent core (,). A strip of generally hydrophobic resilient material (,) is placed between the liquid impermeable sheet (,) and the absorbent core (,) along each longitudinal edge portion (,) of the absorbent core in at least the mid portion (,) to thereby increase the flexure resistance of the article.

Absorbent article

The invention relates to a method and to an apparatus for perforating a web of material intended to form an outer casing sheet of absorbent articles. As the web is advanced, the web is first provided with a large number of mutually separated cuts in the nip defined between raised plateaus on a matrix cylinder and circumferentially extending knife-edges of a cutting cylinder. The web is then deformed transversely to its plane at parts which border on each cut. The invention also relates to a perforated outer casing sheet which includes recesses in the form of mutually adjacent elongated channel-like grooves.

Casing material and a method and apparatus for its manufacture

Disposable liquid-absorbent article having longitudinal liquid barrier

A method of fastening a liquid-impervious sheet (7) to a wound pad (5) that is comprised of an elastic, hydrophilic material and that will expand in all directions when absorbing fluid. The pad (5) is stretched to a given extent both longitudinally and transversally in the plane of the pad and a flat liquid-impervious sheet (7) is then applied to the stretched pad and the load acting on the pad is removed. An absorbent dressing that includes an inventive wound pad (13) is also disclosed.

Method of securing a liquid impervious sheet to a wound pad

The invention relates to a sheathing laminate for an absorbent product, such as a sanitary napkin, a diaper, an incontinence protector or the like, and which is to be used as a liquid permeable top layer, which, when the product is in use, faces the body of the user. The laminate (30) comprises a web (10) of plastic film, to one side of which are fixed two mutually spaced, longitudinal strips (14, 16) of non-woven material, while to the other side of the plastic film web (10)--in an area between the two strips (14, 16) on the opposite side of the plastic film web--there is fixed a longitudinal intermediate strip (26) of non-woven material. When used on an absorbent product, the laminate has perforations (42) at least within a portion of the area of the intermediate non-woven strip (26). The invention also relates to a process for manufacture of the sheathing laminate.

Sheating laminate for an absorbent product, process for manufacture of

An absorbent article, such as a sanitary napkin or incontinence guard, comprises a liquid-impermeable surface layer which is remote from the wearer when the article is worn, a liquid-permeable surface layer which faces towards the wearer in use, and an absorbent pad which is contained between the two surface layers. The absorbent pad is arched in a transverse direction, at least at its center part, and therewith exhibits a convex surface on the side of the pad which faces the wearer in use. The edges of the article are restrained from flexing toward the liquid-permeable surface, and the transverse arch is maintained by a restraining device attached to the longitudinal edges of the article.
