Abstract:
1. A method for the production of a diaper with a main body, consisting of a front portion, a back portion and a crotch portion that lies between them, and placed in a longitudinal direction between legs of a wearer, wherein the main body comprises an absorbent body and lateral portions that are attached on both sides to the back portion and/or to the front portion, said lateral portions extending in a transverse direction beyond lateral longitudinal edges of the main body and connecting the front portion and the back portion to one another in an applied state of the diaper, wherein the lateral portions, at least on the side facing the crotch portion, are configured in such a way that they run obliquely to the longitudinal direction or are contoured to form a leg opening portion, said diaper being produced in its longitudinal direction, and in order to achieve the oblique course or contouring of the lateral portions, material recesses are formed at the lateral portions, characterized in that a material web that forms one of the lateral portions on both sides is conveyed in the longitudinal direction; that the material recesses for achieving the oblique course or the contouring of the lateral portions are formed by making an opening with a continuous circumferential edge in the material web; that subsequently, the material web is divided in the longitudinal direction into partial webs, the separation running through the opening; that sections are cut from the two partial webs, in each case transversely to the longitudinal direction in order to form the lateral portions that are to be applied to both sides, and that the sections are attached to the respective back portion and/or front portion, wherein the partial webs that are formed by the division in the longitudinal direction are supplied such that they intersect one another, so that there is a change of side in relation to the main body, and divided openings then face in each case outward as material recesses in the two partial webs.
