Abstract

Ein Shredder (110) hat einen Rotor (12), der eine Vielzahl von Messern (130, 230, 330) mit mehreren Schneidpunkten trägt, die mit einem Gegenmesser (14) kämmen, das allgemein V-förmige Nuten (26) aufweist. Jedes Messer (130, 230, 330) hat mindestens einen Schneidpunkt , der durch einen Schnittpunkt zwischen zwei aneinandergrenzenden Seitenflächen des Körpers des Messers definiert ist. Die Ecke (134, 234, 334) definiert eine Mehrzahl von Schneidpunkten (140a, b; 240a, b, c; 340a, b, c, d), die entlang einer ersten Richtung voneinander beabstandet sind. Die Messer sind an der äußeren Umfangsfläche des Rotors (12) derart montiert, dass die erste Richtung jedes Messers im Wesentlichen tangential zu der äußern Umfangsrichtung ist und dass die Ecken (134, 234, 334) der Messer (130, 230, 330) während der Drehung des Rotors (12) um seine Achse mit den jeweiligen V-förmigen Nuten (26) in dem Gegenmesser (14) kämmen. Die mehreren Schneidpunkte (140a, b; 240a, b, c; 340a, b, c, d) jedes Messers (130, 230, 330) treffen der Reihe nach auf die Nut (26) und kämmen fortlaufend mit der Nut (26) in dem Gegenmesser (14).

A shredder (110) has a rotor (12) carrying a plurality of knives (130, 230, 330) having a plurality of cutting points that mesh with a counter knife (14) having generally V-shaped grooves (26). Each blade (130, 230, 330) has at least one cutting point defined by an intersection between two adjacent side surfaces of the body of the blade. The corner (134, 234, 334) defines a plurality of cutting points (140a, b; 240a, b, c; 340a, b, c, d) spaced apart along a first direction. The knives are mounted on the outer peripheral surface of the rotor (12) such that the first direction of each knife is substantially tangential to the outer circumferential direction and that the corners (134, 234, 334) of the knives (130, 230, 330) during meshing the rotation of the rotor (12) about its axis with the respective V-shaped grooves (26) in the counter knife (14). The plurality of cutting points (140a, b; 240a, b, c; 340a, b, c, d) of each blade (130, 230, 330) strike the groove (26) in sequence and mesh continuously with the groove (26). in the counterknife (14).
