Abstract
Description
In plan view, the knife has a rectangular base with two parallel longitudinal edges and two parallel transverse edges. The knife has two cutting edges that run parallel to each other and parallel to the longitudinal edges of the base. The knife has a ridge running along the respective cutting edge, oriented parallel to the base. The bridges are based on the principle of the support edge / cutting edge. The knife has a depression between the ridges, extending from one ridge to the other. The depression from one ridge to the other is parallel to the base.
Claims
Knife of a shredding machine,- wherein the knife in plan view has a rectangular base with two longitudinal edges parallel to each other and two transverse edges parallel to each other,- wherein the knife has two cutting edges running parallel to each other and parallel to the longitudinal edges of the base,- wherein a support edge in the form of a rib is provided along each cutting edge, the support surface of which is oriented parallel to the base, and- wherein a depression extending from one rib to the other is formed between the ribs, the bottom of which runs parallel to the base. Knife according to claim 1, wherein each cutting edge adjoins a support edge in such a way that the support edge mechanically supports the cutting edge and acts as a contact / guide surface. Knife according to claim 1 or 2, wherein the recess extends over the entire length of the cutting edges. Knife according to one of the preceding claims, wherein the recess is arranged centrally between the ribs and the knife is substantially symmetrical with respect to a central longitudinal plane that runs parallel to the cutting edges. Knife according to one of the preceding claims, wherein the recess has a constant depth over its extent from one rib to the other rib. Knife according to one of the preceding claims, wherein the support surfaces of the webs lie in a common plane that runs parallel to the base surface. Knife according to one of the preceding claims, wherein the knife is designed as a reversible cutting knife, so that it can be mounted in a reversible manner after wear of a cutting edge. Knife according to one of the preceding claims, wherein the knife has at least one mounting hole or mounting recess for mounting on a rotor or knife carrier. Knife according to one of the preceding claims, wherein the knife is made of wear-resistant steel, in particular tempered or hardened steel.
