Abstract (en)
[origin: EP2298468A2] The ring press has a bolt (24), by which a work piece is fed in an axial direction (BA). A drive (36) is designed such that it is coupled or decoupled with a bearing race in a transmission free manner to transmit the speed or torque normally on the bearing race. The speed or torque is produced by the drive. An independent claim is also included for a work machine, particularly wire or strip bending machine for machining, particularly transformation, of continuous work pieces.
