A method for producing a multiplicity of disposable incontinence diapers having a diaper main part and front and rear diaper side parts attached thereto, characterized by the following method steps of: feeding and conveying an endless diaper main-part web in a first longitudinal direction to a separating and application station; feeding an endless diaper side-part web to the separating and application station, wherein, at the separating and application station, first and second dual-use longitudinal portions following one another and having at least regionally curved edges are severed from the diaper side-part web and are attached to first and second regions of the diaper main-part web, wherein the first and second regions each comprise a hip region of two diaper main parts following one another in the longitudinal direction and adjacent to one another; individually separating the disposable incontinence diapers by separating the diaper main-part web transversely to the first longitudinal direction, wherein the separating is carried out through the longitudinal portions such that a first sub-portion of at least one first respective longitudinal portion forms a rear diaper side part of a first disposable incontinence diaper and a second sub-portion of the respective first longitudinal portion forms a front diaper side part of an immediately adjacent second disposable incontinence diaper, and such that a first sub-portion of a second respective longitudinal portion forms a front diaper side part of a disposable incontinence diaper and a second sub-portion of the respective second longitudinal portion forms a rear diaper side part of an immediately adjacent further disposable incontinence diaper; wherein the curved edges of the longitudinal portions are contoured after being severed from the diaper side-part webs, such that, after the first and second longitudinal portions have been fixed to the first and second regions of the diaper main-part web, each rear diaper side part has a lower edge which has a convex portion, and each front diaper side part has an upper edge which has a concave portion, and such that the length E of an outer edge of a respective front diaper side part is shorter than the length D of an inner edge of a respective front diaper side part; and wherein the longitudinal extent of the front diaper side parts is at least 60% of the longitudinal extent of the rear diaper side parts.
