Abstract
Apparatus for stranding two or more wires together comprising a wire guide means extending in a wire pass direction to a twisting station, the guide means held against rotation about an axis at its upstream end and being rotationally flexible to be torsionally twisted by a rotatable twisting means in the twisting station connected to the downstream end of the guide means. A wire separation tube extends from the twisting means along a fixed curved path section to a stranding station to prevent wires stranding together until they reach the stranding station. The separation tube is rotatable about an axis coinciding with the fixed curved path section and has flexibility to enable the tube to be maintained in its curved configuration along the path with torsional rigidity to avoid build-up and retention of twist.
