ールを提供しようとするものである。In the rotary cutting roll described in the prior art, even when the strand is cooled from the extruder, heat is generated in the rotary cutter and the fixed blade base and the strand is cut. Since the blade type silver brazed part is broken and separated, and the blade tip is greatly chipped, the strands cannot be cut accurately and the rotary cutting roll itself becomes unusable, resulting in a large loss. Had. Therefore, the present invention has been made to solve such a conventional problem, and its object is to detachably attach a cutting blade die on the outer periphery of a rotary cutting roll for cutting a strand. An economically efficient pelletizer that can be fixed and used when the cutting blade die wears or is broken and the cutting blade die is detached only for that part and a new cutting blade die can be attached and fixed. The present invention is intended to provide a rotary cutting roll for a spare blade.

充分に可能であると云う経済的な効果がある。Since the present invention is configured as described above, the rotary cutting roll main body can be manufactured by partially replacing the cutting edge die even if one edge is broken or separated. There is an effect that only the cutting edge die of the damaged edge can be replaced and used. And, unlike the conventional rotary cutting roll, there is no need to replace a new cutting roll, and there is an excellent effect that it is very economical. Further, in the rotary cutting roll main body, by alternately forming the protrusions and the concave fitting portions in the longitudinal direction in the lateral direction of the outer periphery, the cutting blade die and the fixed body can be reliably and easily formed with respect to the concave fitting portion. There is an effect that can be fitted. Further, the fixed body is provided with several bolt holes, and the fixing bolt can be rotatably screwed into the bolt holes, so that the fixed body can be easily detached, and the cutting blade die is damaged and unusable. There is an excellent and practical effect that replacement work is extremely easy. Furthermore, the fixed body does not need to be replaced as a component, and repairing can be performed only with a cutting blade type, which has an economical effect that it can be reused sufficiently.
