摘要： A ram or mandrel having a splined end to effect a die or drives a cup shaped workpiece into engagement with rollers arranged to press radially against the outer wall of the workpiece and force the workpiece material into the valleys between splines thus forming a complementary splined formation of the cup. A plurality of forming rollers are operative as a male die. Each roller is backed by a pair of supporting rollers wherein a forming roller and a pair of backing rollers form a unit radially adjustable relative the workpiece, each such unit being carried in a relatively stationary sector shaped body, all units being surrounded by a common reinforcing radial support ring and carried on a bed plate, there being one such unit for each formation, such as a crevice, to be formed in the workpiece.
