Abstract

Abstract A disposable absorbent article, such as a diaper, an incontinence guard or the like, includes an inner, liquid-permeable casing sheet, which when the article is worn lies nearest the body of the wearer, an outer, liquid-impermeable casing sheet, an absorbent pad enclosed between the two casing sheets, and a layer of fibre wadding disposed between the absorbent pad and the inner casing sheet. The inner casing sheet is joined to the absorbent pad along two longitudinal lines forming permanent fold lines which divide the article, over at least a part thereof, into a central elongated part and two edge-parts located symmetrically on respective sides of the central elongated part. Each edge-part is folded between the respective fold line and its lateral edge such as to form an inwardly upstanding longitudinal fold in the outer casing sheet. The article has mutually opposed portions in the longitudinal folds, which portions are permanently joined to each other, whereby the edge-parts form inwardly upstanding embankment walls.
