Abstract
A flat woven cable having a generally flat construction and a curved portion therein and method for making the same are disclosed. The cable includes a plurality of conductors and a continuous fill strand interwoven in a twill weave to link the conductors together. The cable also includes outer and inner portions wherein the fill strand is interwoven with a lesser number of conductors in the inner area than in the outer area. The cable is free of warp binder strands and fill strand is heat shrunk following formation of the curved portion.
Claims12
A woven electrical cable having a generally flat construction and a curved portion therein comprising a plurality of conductors and a continuous fill strand interwoven in a twill weave pattern to bind said conductors together, a curved cable portion including outer and inner areas wherein said fill strand is interwoven with a lesser number of conductors in the inner area than in said outer area to thereby form an area which is relatively unbound and free of said fill strand and wherein said fill strand is heat shrunk in said curved portion.
A method for forming a woven electrical cable of the type having a generally flat construction with a curved portion therein comprising the steps of:
- a) providing a plurality of longitudinally extending parallel electrical conductors and a heat shrinkable continuous fill strand;
- b) weaving the conductors and the fill strand together in a twill pattern so that the cable has laterally displaced inner and outer portions;
- c) forming at least one void area in the woven pattern by weaving together a greater number of conductors in the outer portion than in the inner portion so that the conductors in the void area unbound by the fill strand;
- d) forming a curved area which incorporates the void area;
- and,
- e) heat shrinking the fill strand in the vicinity of the void area to thereby eliminate the void within the curved portion in the flat cable.
