Abstract
Abstract Apparatus for stranding wires by twisting, comprises a length of flexible tubing through which the wires are fed. One end of the tube is held stationary while the other end is rotated or twisted first in one direction and then the other. Dividers are positioned at spaced intervals along the tube and at or adjacent to the outlet means for twisting the wires are provided. Also provided are means for holding the twisted wires after exiting from the tube.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
Apparatus for stranding wires, comprising: an elongate flexible tubular member having an inlet end and an outlet end; means for holding the inlet end of the flexible tubular member stationary; means for reciprocating the outlet end of the flexible tubular member through a predetermined number of rotations in alternate directions; a plurality of independent dividers axially spaced along the tubular member and extending diametrically across the bore of the tubular member to define a plurality of paths through said bore from said inlet end to said outlet end; twisting means for reciprocation in unison with said outlet, said twisting means including a plurality of apertures, an aperture for each of said plurality of paths.
Claim 2
Dependent Claim
