Abstract

A woven transmission cable formed of a plurality of conductor wires arranged in side-by-side relationship forming an array which extends along a single plane. Coating the conductor wires with a self lubricating insulating material and separating them with warp yarns which are located between adjacent ones thereof. Weaving a weft yarn, formed also of a self lubricating material, to pass alternately over and under the warp yarns and the wires of the array, forming a woven structure in which the wires are capable of longitudinal adjustment relative to the warp yarns and the weft yarns. The longitudinal adjustment allows the cable to be shaped into an arcuate configuration while maintaining the wires along a single plane.

Claims

1. A self-aligning woven transmission cable comprising:

a plurality of coated insulated conductor wires forming at least one array, said wires being arranged to extend in side-by-side relationship along a single plane, said coated wires coated with a self-lubricating material which provides a substantially frictionless outer surface;

a plurality of non-conductive warp yarns arranged across said at least one array and between said wires;

a weft yarn interwoven with said warp yarns and said wires in a plurality of picks, each of said picks passing completely across said at least one array and successively over and under said wires in said single plane;

an arcuate path provided on a portion of said cable wherein at said arcuate portion, said weft yarn still passing successively first over and under each of said wires then over and under each of said warp yarns to maintain said wires in said single plane;

said at least one array comprising a plurality of arrays in adjoining relationship to form said transmission cable which is a unitary cable and also comprises said arcuate path and a metal shield member between each of said arrays within said transmission cable.

2. A woven transmission cable of selected weave shaped into an arcuate configuration comprising:

a plurality of conductor wires arranged in spaced side-by-side relationship along a single plane forming at least one array, said wires being coated with a self lubricating insulating material which provides a substantially frictionless outer surface;

a plurality of warp yarns arranged between each of said conductor wires forming said array, said warp yarns being positioned in undulating manner along said single plane;

a weft yarn passing in successive picks completely across said array while being positioned alternately over and under each of said warp yarns and first under and then over each of said conductor wires of said array along the entire length of said array;

said at least one array comprising a plurality of arrays in adjoining relationship and a metal shield provided adjacent each of said arrays wherein each of said shields and each array of said arrays being secured together to form said woven cable as a unitary cable; and

causing a portion of said unitary cable to be shaped into said arcuate configuration with said weft yarn remaining positioned over and under each of said conductor wires and each of said warp yarns along said arcuate configuration to retain said conductor wires of each of said arrays aligned along said single plane.

3. The cable of claim 2 wherein said self-lubricating insulating material includes polytetrafluoroethylene.

4. The cable of claim 2 wherein said weft yarn includes polytetrafluoroethylene.

5. The cable of claim 2 wherein said weft yarn comprises a shaped monofilament including polytetrafluoroethylene.

6. The cable of claim 2 wherein said warp yarns include polytetrafluoroethylene.

7. The cable of claim 2 wherein said warp yarns comprise synthetic monofilaments.

8. The cable of claim 2 wherein said metal shields comprises copper foil.

9. The cable of claim 2 including a tubular outer shield in which said unitary cable is encased.

10. The cable of claim 2 wherein said conductor wires of each of said arrays are adjusted longitudinally allowing said unitary cable to conform into said arcuate configuration with said conductor wires remaining along said single plane.

11. The cable of claim 2 wherein said metal shields are shaped to conform with said arcuate configuration of said arrays.
