Abstract
An apparatus and method for forming a single strand wire with improved flexibility and a stranded cable from a single strand wire. In one embodiment, the flexible single strand wire has a solid, single strand wire body and at least one helical groove formed on an outer circumferential surface of the wire body. The stranded cable includes a plurality of strands. In one embodiment, one of the strands has a planar surface that extends along a longitudinal axis of the cable body.
Claims7
A stranded cable formed by a process comprising the steps of:
- (a) providing a source of generally cylindrical single strand wire defining a longitudinal axis;
- (b) twisting the single strand wire in a first direction about the longitudinal axis;
- (c) severing the generally cylindrical single strand wire along the longitudinal axis to form at least two severed strands, wherein the severed strands include a planar portion and an arcuate portion;
- (d) joining the severed strands together such that the arcuate portion of the severed strands define a substantially continuous and uninterrupted circumferential surface, wherein a planar portion of a severed strand is adjacent a planar portion of another severed strand when the severed strands are joined together to minimize gaps between the joined strands;
- and
- (e) twisting the joined strands in a second direction about the longitudinal axis to form a stranded cable.
