    摘要： A die cut roll comprising a die cutter provided with a projecting push-cutting edge formed in conformity with the shape of an uncut product and disposed on the surface of a rotary drive roll and an anvil roll, wherein, in order to improve the cutting performance and service life of the tip of the push-cutting edge, (1) a finishing inclined surface is formed by grinding to provide a grinding stripe which is adjacent to the smooth tip portion of the cutting edge tip and forms an angle of 50 to 90° with a ridge line constituting the smooth tip portion, (2) a push-cutting edge that does not directly function in cutting is provided so as to make up for a discontinuous portion in a circumferential direction of the rotary drive roll of the push-cutting edge of the die cutter, and (3) a plurality of ends of the push-cutting edges are overlapped one another in their circumferential directions.

    摘要： A die cut roll is provided which comprises a die cutter obtained by providing on a surface of a rotary driving roll with projecting pressure cutting blades formed in accordance with the shape of a product to be cut, and an anvil roll adapted to receive the edges of the projecting pressure cutting blades of the die cutter, and which has an improved cutting performance of the edges of the projecting pressure cutting blades and a prolonged lifetime.

    1. Inclined finishing surfaces are formed adjacently to a top smooth portion of an edge of each of the projecting pressure cutting blades, by grinding each of surface portions adjacent to the top smooth portion so that the surface portion has grinding flaws making an angle φ of 50°-90°, and preferably 80°-90° to a relative ridgeline defining the top smooth portion.
    2. A difference between the hardness of the cutting blades of the die cutter and that of the surface of the anvil roll is set different in die cut rolls of different driving systems, i.e., a two-shaft driving system and a single-shaft driving system.
    3. Projecting pressure cutting blades not directly working to cut a product are provided so as to compensate for at least the discontinuous portions, which extend in the circumferential direction of the rotary driving roll, of the product cutting projecting pressure cutting blades of the die cutter.
    4. Connected portions of plural product cutting projecting pressure cutting blades on the die cutter form a continuous linear cutting blade.
    5. Plural projecting pressure cutting blades are provided with their end portions disposed side by side in the circumferential direction of the die cutter.

    A die cut roll having excellent cutting characteristics, a prolonged lifetime and a high reliability can be obtained by minimizing the occurrence of minute chippings and abnormal abrasion of the projecting pressure cutting blades and effectively reducing stress concentration on the edge of each cutting blade.

    摘要： 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
