Abstract
The present invention refers to an apparatus for removing damaged portions of rubber components, in particular of steel-braced radial-ply tyres, including a driven and rotating tool. The tool (1) consists of a sleeve whose wall thickness tapers like a knife in the tool operating direction thus forming essentially an edge (9) and the front edge (9) of the tool has formed therein notches (7). It will be expedient when the outer circumferential surface (11) of the sleeve extends essentially parallel to the axis (13) thereof, and it will be expedient when the inner circumferential surface (15) extends at an oblique angle outwards in the front area of the sleeve. The sleeve can consist of a cutting crown (3) and of a carrier sleeve (5), the cutting crown (3) being preferably made of a material of high hardness, in particular of hard metal (FIG. 1).
