Unitary woven jacket and electrical transmission cable and method of making same
First Claim
Patent Images
1. A jacketed unitary woven electrical transmission cable which includes an outer woven cover having outer woven cover fabric and an inner woven electrical transmission cable having woven transmission cable fabric, said unitary woven electrical transmission cable comprising:
- a plurality of transmission cable warp elements which includes a number of elongated electrical conductors extending in a warp direction in said woven electrical transmission cable;
a transmission cable weft yarn woven with said transmission cable warp elements to define said woven transmission cable fabric;
said outer woven cover woven about said woven electrical transmission cable;
said outer woven cover including a cover weft yarn woven with a plurality of cover warp yarns to define said outer woven cover fabric; and
said cover weft yarn being woven with a portion of said transmission cable warp elements in said woven electrical transmission cable fabric along the length of said cable so that said woven transmission cable fabric and said outer woven cover fabric are physically attached in a one-piece woven construction.

Abstract
A woven jacket (A) and woven transmission cable (B) are woven together as one-piece. A common weft element (18) is interwoven between the cover (A) and cable (B) which are woven simultaneously on a loom. Weft pick (18a) is woven in the cover exclusive of the cable while weft pick (18b) is broken out of the cover and woven in the cable to physically attach these together.

7. A method of constructing a unitary jacketed woven electrical transmission cable of the type which includes a woven outer cover and an inner woven electrical transmission cable having a plurality of warp elements including a number of elongated electrical conductors extending in a warp direction of the cable comprising:
-
weaving said transmission cable warp elements and a first weft yarn together to form said inner woven electrical transmission cable; simultaneously weaving a plurality of cover warp yarns and a second weft yarn to form said outer woven cover about said inner woven transmission cable while said transmission cable is being woven; and interweaving one of said weft yarns with one of said warp elements so that said inner woven electrical transmission cable and said outer woven cover are simultaneously woven and attached together as one-piece. - View Dependent Claims (8, 9, 10)

11. A method of weaving a one-piece jacketed woven electrical transmission cable having an outer woven cover and an inner woven cable having a plurality of conductors extending in a warp direction comprising:
-
weaving a common weft element with a plurality of cover warp elements to define outer woven cover fabric; weaving said common weft element with a number of transmission cable warp elements to define woven cable fabric; and weaving said common weft element with selected ones of said cable warp elements at alternate picks of said weft element along the length of said woven cable exclusive of said woven cover fabric; whereby a one-piece jacket construction is had preventing slippage between said outer woven cover and said inner woven cable to reduce abrasion. - View Dependent Claims (12, 13, 18)

14. A method of constructing a flexible woven electrical transmission cable and outer cover surrounding and jacketing said cable so that slippage between the cable and outer cover is avoided and wear and abrasion of the cable is reduced, said woven cable being of the type having a number of cable warp elements which are electrical conductors extending longitudinally in a warp direction of said cable, said method comprising:
-
weaving a transmission cable weft element with said cable warp elements to define a woven electrical transmission cable; weaving an outer cover simultaneously with weaving said woven transmission cable about the outside of said woven transmission cable by weaving a plurality of cover warp elements with a cover weft element; interweaving at least one of said weft or warp elements of said woven cover with at least one of said weft or warp elements of said woven electrical transmission cable to physically attach said woven cover and woven electrical transmission cable together as one-piece thereby reducing relative movement therebetween. - View Dependent Claims (15, 16)
