ABSTRACT:
A device (1) is used for twisting rope-shaped material (15), particularly of a larger cross section, with changing twist direction (SZ), consisting of a rotor (4) that changes direction and/or RPM, with two opposing chain drives (7) for the material (15), which are parallel to the rotor axis along an endless path. The material is gripped, guided and subsequently released by collet chucks along a prescribed pathway determined by a pressure rail (16). The collet chucks (14) are additionally attached to the chain drives (7) outside of the pathway, and are force-guided along the endless path.
