A method for producing a web of a laminate material for retaining faeces including laminating first and second webs to form an intermediate laminate web, providing transversal slits in the intermediate laminate web and expanding the intermediate laminate web such that the slits are opened to openings. An expanded intermediate laminate web is formed by the expansion. The expanded web is laminated to a third web in order to fix the expanded web in an expanded state, whereby the laminate material web is formed. Also, a method of producing an absorbent article including producing the laminate material web according to the method above.

A packaging unit formed from a sheet of material having an inner surface, an outer surface and one folding axis dividing the sheet into a first region and a second region. The inner surface includes an inner edge portion and an outer edge portion, wherein one of the inner edge portion and the outer edge portion of the edge zone of the first region is provided with adhesive, and the other of the inner edge portion and the outer edge portion of the edge zone of the first region is adhesive-free. One of the inner edge portion and the outer edge portion of the edge zone of the second region is provided with adhesive, and the other of the inner edge portion and the outer edge portion of the edge zone of the second region is adhesive-free in a complementary manner to the edge zone of the first region.

Absorbent nappy/diaper pads composed of a first absorbent base material, and a second absorbent material consisting of superabsorbent polymer powders, are made by a unit () that comprises a conveyor () carrying the first absorbent material along a predetermined feed path (P), and a feed system () by which the superabsorbent polymer powders are released onto the feed path (P); the feed system () comprises a fixed duct () with an outlet () directed at the feed path (P), and a valve (), positioned along an intermediate segment of the duct (), by which the superabsorbent polymer powders are dispensed intermittently and controllably. The valve () comprises a rotating disc (), set transversely to the duct (), with an annular region () that revolves through a gap () in the duct () and presents at least one slot () delimited longitudinally, in the direction of rotation of the disc (), by a leading edge () and a trailing edge (); the radial dimension of the slot () increases progressively, at least along a part of the distance from the leading edge () toward the trailing edge ().

An absorbing article, in particular an absorbing structure has at least one layer that can be used with advantage as a surface layer or in combination with a surface layer. The aforementioned layer has deformable fibers which are deformed and shrink when they become wet. The aforementioned layer thus constitutes a deformation layer and has at least one distinct admission passage. The admission passage is deformed and dilated when it becomes wet. In addition to improved admission in conjunction with repeated wetting, the article also offers a solution to the problem of feces handling in combination with repeated wetting.

A pant-type absorbent article having a first body panel and a second body panel, the first and second body panels being interconnected by side panels. The respective side panel is formed by a bridge member having a first longitudinal edge portion attached to the first body panel and a second longitudinal edge portion attached to the second body panel, the bridge before use of the article being folded in an accordion-like fashion and can be extended and unfolded when the article is to be used so as to form the side panels of the article. In one embodiment at least one of the bridge members is refastenably attached to one body panel, wherein a first fastening member is arranged on the bridge member at or close to one longitudinal edge portion thereof and a complementary second fastening member is arranged on the respective body panel.

A method of strengthening a boundary region between a first portion and a second portion of a fibrous body for absorbent articles. This boundary region is provided with a pattern of compressed spots, the amount of compression being gradually increasing in a direction leading away from an edge of the first portion of the fibrous body. Also, an apparatus for performing the method and an absorbent body having a strengthened boundary region.
