ABSTRACT:
An apparatus for manufacturing pulley rims has a first press, for initially shaping a pulley rim from a pulley rim blank, a second press, for final shaping of the pulley rim, and a clamping assembly for holding and transporting a pulley rim blank between the first press and the second press. Each of the first and second presses include a pair of dies with opposing frusto-conical portions, one of each pair of dies having a cylindrical forward extension which is adapted to extend into a central bore in the other of the pair of dies. The clamping assembly has a pair of semi-cylindrical clamping members with opposed clamping surfaces shaped to conform to the circumference of a finished pulley rim.
