Abstract
Cutting blades and counterblades are presented having long edge life for chopping devices equipped with blades mounted on rotating drums and with counterblades which fit into the gaps between the blades, the blades and/or counterblades being produced by rolling at least one of the longitudinal edges of a piece of flat strip material to form a slightly rounded, prismatic cutting edge, the rolling being continued until satisfactory sharpness is obtained.
Claims21
A process for producing a chopping blade for chopping devices equipped with rotating drums on which blades are mounted in a stationary or rotating manner, the process comprising:
- rolling at least one longitudinal edge of a flat strip into a prismatic shape with a slightly rounded cutting edge to obtain a chopping blade with a prismatic cutting edge of satisfactory sharpness.
A process for producing a chopping blade for chopping devices equipped with rotating drums on which blades are mounted in a stationary or rotating manner, the process comprising:
- providing a strip of flat starting material;
- rolling at least one longitudinal edge of the strip into a prismatic shape with a slightly rounded cutting edge to produce a chopping blade having a prismatic cutting edge with a rolled texture extending over at least part of the length of the longitudinal edge;
- and
- forming a fastening zone including at least one hole in the chopping blade.
