ABSTRACT:
The invention relates to a rotary cutter for the pelletization of plastic extrudates, said rotary cutter being provided with knives projecting axially away from its end surface, said knives being individually affixed to supporting surfaces of the rotary cutter by means of fastening elements. The supporting surfaces are formed by the side walls of radial grooves in the peripheral surface of the rotary cutter and by radial transverse walls in the radial grooves, said radial grooves being limited by the radial transverse walls, the knives each being inserted in hook-like manner with a projecting portion into said radial transverse walls, wherein one side of the projecting portion forms an abutment for the fastening element, said fastening element penetrating a radial transverse wall and pressing on the abutment.
