Abstract

A curved woven cable having a plurality of conductors and a method for constructing the same is disclosed wherein warp binder strands and a fill strand are interwoven with the conductors with at least one void area being formed in which the conductors are not interwoven with the warp strands and fill strands so that the cable may be curved. In a preferred method, the void area is formed by weaving the warp strands and fill strands with the conductors removed from the weave to form a weave portion floated outside of the conductors but which remains an important structural portion of the cable in maintaining its curved configuration.

Claims

1. A curved woven electrical cable having a generally flat configuration comprising:

a plurality of conductors;

a woven cable portion including a plurality of warp binder strands and a fill strand interwoven with said conductors to bind said conductors together; and

a curved cable portion including at least one void area wherein said conductors are present but are not interwoven with said warp strands and said fill strand leaving said conductors relatively unbound in said void areas.

2. The cable as set forth in claim 1 wherein said warp strands and said fill strand are interwoven in said void areas excluding said conductors to define a weave portion floated outside of said conductors.

3. The cable as set forth in claim 1 including a plurality of said void areas spaced along the length of cable in said curved portion.

4. The cable as set forth in claim 2 wherein said curved cable portion includes said woven cable portion wherein said conductors are bound contiguous with said unbound conductors of said void areas.

5. The cable as set forth in claim 1 wherein said void areas are spaced inwardly radially from said woven cable portion.

6. The cable as set forth in claim 5 wherein said woven cable portion is formed between adjacent void areas.

7. The cable as set forth in claim 2 wherein said fill strand is continuously woven through said floated weave portion and said woven cable portion which is contiguous with said floated weave portion in said curved cable portion.

8. The cable as set forth in claim 1 wherein said fill strand is broken out from said woven cable portion at different points across the width and length of said curved portion to form said void area.

9. The cable as set forth in claim 1 wherein said void area is bounded by said woven cable portion.

10. A method for forming a curved portion in a woven electrical cable of the type formed from a plurality of conductors arranged in a side-by-side generally flat configuration and a plurality of warp binder strands and a fill strand interwoven with said conductors to define a woven cable portion in which said conductors are bound comprising the steps of:

providing at least one void area in said cable in which said conductors are present but are not interwoven with said warp strands and said fill strand so that said conductors are relatively unbound in said void area;

bending said cable about said void area so as to assume a desired curved configuration.

11. The method as set forth in claim 10 wherein said void area is provided by interweaving said warp strands and said fill strand outside of said conductors to form a weave portion floated outside said woven cable portion.

12. The method as set forth in claim 10 comprising the step of applying a conforming coating to said curved portion of said cable for maintaining said curved configuration.

13. The method as set forth in claim 10 wherein said void area if formed by breaking out said fill strand from said conductors at different points across the width and length of said cable.

14. The method as set forth in claim 10 comprising forming a plurality of said void areas as required for bending said cable into said curved configuration.

15. The method as set forth in claim 11 wherein said fill strand is woven continuously across said woven cable portion and said floated weave portion.
