Abstract
The invention relates to a method for producing an absorbent disposable incontinence diaper (2), having a main part (4) comprising an absorption element (12), comprising a front region (6) having front side longitudinal edges (26), a rear region (8) having rear side longitudinal edges (25) and a crotch region (10) arranged there between and placed between the legs of a user, and having rear side sections (20) joined to the rear region (8) and front side sections (22) joined to the front region (6) on both sides, which extend in a transverse direction (30) of the disposable incontinence diaper (2) beyond the side front and rear longitudinal edges (25, 26) of the main part (4) and are spaced apart from one another in a longitudinal direction (18) of the disposable incontinence diaper (2), the rear and front side sections (20, 22) being connectable detachably to each other in order to apply the disposable incontinence diaper (2), characterized in that for the purpose of contouring leg opening regions (38) on both sides of the disposable incontinence diaper (2), the rear side sections (20) and/or the front side sections (22) are formed by a severing operation of side section webs (44, 72) that are supplied endlessly and are contoured in the process, and an endlessly supplied main part web (40) is folded in transversely with respect to the plane of the web and transversely which respect to the machine direction (42) before the endlessly supplied side section webs (44, 72) are joined, in that the side section webs (44, 72) are then joined onto the main part web (40), the severing operation (52) covering the side section webs is then carried out on both sides, so that the combination comprising the main part web (40) and joined side section webs (44, 72) can then be accelerated in the machine direction (42) and unfolded in the process, wherein the front and rear side sections (20, 22) can be spaced apart from each other in the longitudinal direction (18).
