Abstract
In order to enable a friction ring comprising a supporting ring and a sintered friction lining to be produced without sintering the friction lining to an intermediate carrier, one initially forms a self-supporting moulded ring (7) from a compacted dry powder material (1), by pre-sintering or bonding using a bonding agent, whereafter the moulded ring is pressed into the supporting ring and the friction lining is produced by final sintering.
