Abstract

A high-speed twisting machine for stranding wires or the like wherein there are a plurality of rotor units or assemblies, one on each side of a cradled take-off spool, each rotor unit consisting essentially of a rotatably driven hollow bearing tube with inlet and outlet openings for the transported wires in combination with open-ended concave guide pots attached at their base to the opposing faces or ends of the bearing tubes on either side of a cradled take-off spool, the outer peripheral guide surface of each pot being symmetrical around the machine axis to define a curved surface corresponding closely to the path of the transported wires taken off during normal twisting operation. The wire openings or bores near the end of the bearing tube must be located outside the curved guide surface of the guide pot connected to the same tube end to provide easy access and visibility. A retaining ring is preferably mounted at the rim concentrically around the open end of each guide pot to control a so-called ballooning effect. The twisting machine is useful for a wide variety of twisting or stranding operations requiring rapid transport of a plurality of wires or the like.
