ABSTRACT:
A method and apparatus for producing a disc structure. The disc provides a radially extending annular wall formed by pressing a workpiece against a contoured tool with a pressure roll. The contoured tool and workpiece move relative to the pressure roll about a first axis while the tool and pressure roll move toward each other in the direction of the first axis. The pressure roll rotates about a second axis perpendicularly intersecting the first axis and provides a cylindrical working surface. The tooling is arranged to radially confine the workpiece. In one embodiment, the tool is formed with a plurality of ribs extending in the direction of the first axis. These ribs cooperate to produce annular grooves in the workpiece along the surface thereof remote from the pressure roll. One embodiment provides a disc particularly suited for use in electromagnetic clutches. The other embodiment may be used to produce wheels, pulleys, and the like.
