Cutting-roller holder

In a cutting-roller holder in which the cutting roller mounted as a loose roller on an axle rotates in a window of a roller cage and can be fitted from the inside of the window until bearing surfaces come to bear, formed next to clamping surfaces on both axle stubs and in the roller cage, and can also be secured with bearing wedges which can be drawn in with their wedge surfaces or their wedge-back surfaces between the [lacuna] on the clamping surfaces of the axle stubs and the clamping surfaces of the roller cage at an acute angle to the window plane from the rear side of the roller cage by means of draw-in screws when the bearing surfaces formed on the axle stubs bear on the bearing surfaces of the roller cage and can be fastened by means of the draw-in screws, provision is made according to the invention for the bearing surfaces of the roller cage and of each axle stub to be designed as plane surface pairs converging at an angle to the window plane, of which one surface pair runs essentially perpendicularly to the window plane and the other surface pair runs parallel to and up to an acute angle to the window plane, and for a clamping wedge to be allocated to each axle stub, the wedge-back surface of which clamping wedge, in the same way as the clamping surface formed on the axle stub and allocated to this wedge-back surface, is arranged parallel to the clamping plane running through the two draw-in screws, while the wedge surfaces of the clamping wedges and their mating surfaces in the roller cage are arranged on the opposite side of the clamping plane.
