ABSTRACT:
A method of manufacturing wire ropes, in which a translational motion is imparted to wires (2) fed from reels and before the twisting of these wires around the core member (11) they are given a residual deformation by way of subjecting each wire (2) to a flat bending on one support (3) and to a helical bending in the direction revolved relative to the direction of the flat bending. A wire rope twisting machine in which a device for imparting a residual deformation to the wires (2) is secured on an output portion of a hollow shaft (14) coaxially therewith includes a body (23) on which are installed for each wire (2) two supports (26, 27) arranged in succession. The first support (26) is installed for free rotation about its geometrical axis (28a) and the second support (27) is installed for free rotation relative to its geometrical axis (31a) and for a setting turn about an axis (33a) disposed perpendicularly to the geometrical axis (31a) of the second support (27).
