ABSTRACT:
Apparatus for stranding wires and covering them in plastics insulation by providing a rotationally flexible elongate member with spaced wire guiding elements, twisting means for twisting the member alternately in opposite directions, and an extension to the elongate member, the extension lying radially within an annular extruder barrel and terminating adjacent the extrusion orifice. In an arrangement for simultaneously stranding wires into different groups and covering the groups within the same insulation, reversible driving means for two or more elongate members is mounted upon a frame. Preferably, each elongate member has its own individual driving means.
