  • Patent number: 4414802
    Abstract: Wire stranding apparatus having a single tube defining a single axial passage providing at least two side-by-side feedpaths for wire, the passage being shaped to prevent wires from moving across from one feedpath to another. The tube is rotationally flexible to torsionally twist it in alternating directions by use of a twisting means at its downstream end while the upstream end is held against rotation. Change in twist direction occurs after a predetermined number of rotations of the twisting means. To accommodate axial contraction and extension during twisting, the tubular means has an axially acting resilient means which maintains axial tension in the tubular means.
