Abstract
Abstract There is disclosed a device for varying the relative locations of stranded wires in a cable during the manufacture of such cable comprises a plurality of wire guides, one for each wire, for guiding the wires as the same are fed into a wire twisting machine. The wire guides are independently movable between two limit positions extending across the generally parallel travel path of the wires so that each of the wires can be guided in any selected position relative to the position of the other wires in the cable.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
152 words
Apparatus for manufacturing a telephone cable which includes a plurality of twisted conductors comprising a source of individual conductors, a conductor twisting means, conveying means for moving individual conductors along individual substantially parallel paths to said conductor twisting means, a plurality of wire guides disposed in the path of the conductors fRom said source to said twisting machine, each of said wire guides supporting a different one of the conductors, means for selectively and individually moving each of said wire guides to different positions along lines substantially transverse to the substantially parallel paths so that each of the conductors can be directed to an arbitrary position relative to the positions of the other conductors and forming means, downstream from said wire guides, for forming the conductors into a flat planar array of parallel conductors wherein the positions of the conductors within the array are determined by the positions of said wire guides.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
The apparatus of claim 1 wherein said forming means includes a rotating planar cylinder and an endless band opposite said cylinder for pressing the conductors to form the first planar array.
