Abstract (en)
[origin: EP1495818A1] The ring production process is for rings of constant wall thickness such as cam rings and involves cold deformation by shaping jaws. There are two flat-disk shaping jaws (e.g. 1) in a frame bed opposite each other and moving reciprocally. There is an endless transporting belt (4) running transversely to the shaping jaws and below them.
