Abstract

Apparatus for making a metallic, non-rotationally symmetric ring with substantially constant wall thickness about its circumference, in particular a cam ring, from a circular ring, includes frame bed and a forming tool which is supported by the frame bed. The forming tool has an inner contour which approximates a finished contour of a non-rotationally symmetric ring, and includes two die members which are constructed in the form of two flat disks in opposite disposition and movable back and forth. Arranged in an area between the die members is an endless transport belt which is constructed to move in a production clock cycle and to move transversely to the die members. The transport belt has an upper strand extending in immediate proximity underneath the die members.
