Abstract:
1. A device for the manufacture of an absorbent product, comprising a rotatable slitting tool for the intermittent processing of the absorbent product, having an extent in a radial direction and an extent in an axial direction perpendicular to the radial direction, the slitting tool being divided in the axial direction into two lateral parts and lying between them a central part, wherein the central part comprises a circular cross section in the radial direction, and the lateral parts comprise, in the axial direction, intermittent protuberances projecting from the central part, wherein protuberances are the same distance from the center of the slitting tool as the circular cross section, and wherein the central part between the protuberances, in the direction of curvature of the envelope surface, forms a plurality of cutting edges, each of which has a width which, at a given pressure, permits slitting of a layer of material intended for the absorbent product, and the protuberances form supporting surfaces between the cutting edges.
