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.
