Abstract
A hollow shaft (4) connected to a drive motor is supported in a machine housing (2) in such a way as to act on a rotary coupling (13) with at least two coupling jaws (28, 29). These jaws are held with freedom of radial and axial movement in recesses (23) in a jaw holder (14), which is able to rotate with the hollow shaft, the recesses being bounded by parallel surfaces (24, 25). The jaws can be pressed radially against the spiral wire rod under the action of a control device (16). To increase the operating reliability and to make it easier to replace the coupling jaws, one end of the hollow shaft (4) is connected nonrotatably with respect to a coupling housing (9), the circumference of which is at least mostly closed, and the jaw holder (14) with the coupling jaws (28, 29) is supported in the coupling housing (9) in such a way that it is not free to rotate but can be removed in the axial direction.
