Abstract
Wire stranding apparatus having tubular means having passage means to provide wire feedpaths, the tubular means being rotationally flexible about an axis, being held against rotation about this axis at an upstream end and having twisting means to cause alternating torsional twisting at its downstream end. The feedpaths are held in fixed positions apart either along the whole length of the tubular means where the tubular means is a single tube with at least two side-by-side passages or comprises tubes with their outer surfaces in continuous contact. When the tubular means comprises two or more spaced tubes, these are held in fixed relative positions at spaced locations along the tubes. To accommodate axial contraction and extension during twisting, the tubular means has an axially acting resilient means which maintains axial tension on the tubular means.
