| 摘要 |
<p>The invention relates to a device (9) for the manufacture of an absorbent product comprising a rotatable slitting tool (1) having an extent in a radial direction and an extent in an axial direction perpendicular to the radial direction, the slitting tool (1) being divided in the axial direction into two lateral parts (3) and lying between them a central part (4). The invention is characterized in that the central part (4) has a circular cross section in the radial direction, in conjunction with which the lateral parts (3) comprise, in the axial direction, intermittent protuberances (5) projecting from the central part (4), which protuberances (5) follow the same radius (R) as the circular cross section, the central part (4) between the protuberances (5), in the direction of curvature of the envelope surface, forming a plurality of cutting edges (6), each of which has a width which, at a given pressure, permits slitting of a layer of material (10) intended for the absorbent product, and the protuberances forming supporting surfaces (8) between the cutting edges</p> |
