Abstract

The manufacturing method is for a brake block having a body (1) and a friction bit (5,6). The friction bit is pressed fast to the body with the aid of heat effect, so that the central region (6) of the bit is harder than the margins. The friction bit comprises two courses of different hardness material. The courses are placed on the body, with the harder material against the body. The materials are then pressed together, and at the same time pressed fast to the body. The harder friction material is freely allowed to flow into a widening in the lower part of the press. The two courses are pref. pre-stressed to become two coherent pieces, before they are placed on top of one another on the body, for the final pressing operation.
