Abstract: An absorbent disposable article including an absorbent body covered, on one side by an impervious sheet, and on the other side, by a porous cover layer. An impermeable protective layer, having a coarse side and a smooth side, is provided along the edges of the porous cover layer, with the coarse side facing the porous cover layer. The impermeable protective layer is pressure bonded to the porous cover layer to produce a liquid impervious barrier.

Abstract: In an absorbent disposable article, such as in particular a diaper, in which an absorbent body is covered on one side by a liquid-impermeable protective sheet and on the opposite side by a porous layer, certain edge areas of the porous cover layer should be provided with a liquid-impermeable protective layer.This protective layer is formed as a prefabricated impervious sheet and possesses, before being placed on cover layer, on one side a smooth and the other side an extremely coarse surface. The impervious sheet serving as the protective layer penetrates essentially exclusively with its coarse surface areas inside the cover layer. Through the smooth side of this impervious sheet, an absolute imperviousness is assured. Because of the physical bond, which forms between the impervious sheet and the cover layer, the impervious sheet can be formed extremely thin, i.e., a minimum amount of material is sufficient for the impervious sheet.
