Abstract
A disc-shaped cutter body (1; 101; 201) is provided with a multiplicity of tooth plates (4; 104; 204, 204a), which engage suitable backing and end-supporting surfaces (5, 6, 7; 105, 106, 107, 205, 205a, 206, 206a, 207, 207a) of tooth holders (3; 103; 203) inserted in recesses formed by radial grooves (2; 102; 202) in the cutter body. Each tooth plate is clamped between a tooth holder and a head portion (9; 109; 209a, 209b) of an elongated holding-back member (8; 108; 208), which has a foot portion (10; 110; 210) that is disposed in the recess of the cutter body and bears on said tooth holder. To enable the tooth plates to be reliably fixed in a narrow cutter body by means which involve only a small expenditure and with a controlled clamping force and to facilitate the handling of the tooth plates and the means for fixing them, each tooth plate (4; 104; 204, 204a) is held in position by the head portion (9; 109; 209; 209a ) of a resilient holding-back member (8; 108; 208), which between its head and foot portions bears on a surface (12; 112; 212) of the recess in the cutter body.
