Abstract
To make a friction ring which is intended to be used in clutches or brakes and has a sinter-bonded friction facing, an annular blank is blanked from flat sheet metal and is provided with a sinter-bonded friction facing. Thereafter the blank provided with the sintered friction facing is shaped to form a conical or cylindrical friction ring and grooves distributed around the periphery of the friction facing are embossed into the friction facing at the same time. In order to ensure that that shaping operation will result in an adequate dimensional accuracy, the operation to emboss the grooves into the friction facing is carried out in such a manner that the backing ring is similarly embossed.
