Abstract
1. A rotary cutting tool, more particularly for the continuous granulation of plastics, having a cylindrical tool body (1, 100) formed with a number of longitudinal grooves (2) uniformly distributed in the peripheral direction, each of which contains a releasably inserted, strip-like cutting element (6, 6a, 6b) and a clamping element (7) of wedge shaped cross-section which is disposed in the space, tapering in wedge shape in the direction of the periphery of the tool body (1), between a bearing surface (12) of the cutting element and the side wall (13) of the longitudinal groove opposite said bearing surface and has in cross-section a matching wedge shape tapering in the same direction and is pressed radially outwards by clamping means (16; 17; 18; 22) borne in the zone of the bottom (15) of the longitudinal groove into the space tapering in wedge shape, so that the cutting element is clamped via a clamping surface (11) remote from the clamping element against a seating surface (5) in the zone of the longitudinal groove, characterized in that that part of the cutting element which extends into the longitudinal groove in the tool body or in a member (35) connected thereto and is bounded by the clamping and bearing surfaces (11, 12) has a substantially wedge shaped cross-section tapering in the direction of the periphery of the tool body (1, 100) and having a maximum width smaller than the opening width of the longitudinal groove, and the tool body or the member (35) connected thereto has a bearing surface (14, 140) for the cutting element which determines the radial position of the cutting element.
