Abstract
Abstract A continuous process of drawing a plurality of strands from a supply and neuturalizing the twist as taken from supply reels, twisting the various strands into a cable and then passing the cable over capstans and an accumulator to maintain proper tension in the cable and then on to a closer where the cable is packaged, all units being driven from a common shaft in time with each other and in a one-to-one relationship with the elimination of back twist in individual strands and the maintenance of uniform tension on the individual strands and a minimum tension on the cable.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
A cabling apparatus for twisting together a plurality of strands comprising a pay-off neutralizer for each strand, each neutralizer having a hollow shaft, a reel axially mounted relative to said shaft, a flyer rotatably mounted about said reel, each cable strand passing from said reel about the flyer and thence through said shaft to a twister, means rotating said flyer, said twister including an accumulator and capstan rotating in a frame, means rotating said frame, take-up means to package the cable, means rotating said take-up means, said means rotating said flyer, frame and said take-up means driving each of said elements in a one-to-one relationship.
Claim 2
Dependent Claim
105 words
A cabling apparatus for twisting together a plurality of strands comprising a pay-off neutralizer for each strand, each neutralizer having a hollow shaft, a reel axially mounted relative to said shaft, a flyer rotatably mounted about said reel, each cable strand passing from said reel about the flyer and thence through said shaft to a twister, means rotating said flyer, said twister including an accumulator and capstan rotating in a frame, means rotating said frame, take-up means to package the cable, means rotating said take-up means, said means rotating said flyer, frame and said take-up means driving each of said elements in a one-to-one relationship.
Claim 3
Dependent Claim
21 words
A cabling apparatus as in claim 1 wherein the means rotating said flyer, frame and take-up is an elongate driven shaft.
Claim 4
Dependent Claim
51 words
A cabling apparatus as in claim 1 wherein tension of each strand is sensed at the output of each pay-off and first control means are provided to maintain substantially constant tension, and wherein the cable tension is sensed before the take-up, and second control means to maintain substantially constant cable tension.
