Abstract
Abstract This invention relates to apparatus for stranding filaments, such as wire, and in one embodiment comprises a lightweight frame with low centripetal and friction force generating characteristics for mounting a spool containing a multiplicity of parallel-wound wires on a "floating" bed, and imparting twist to the wires prior to the finished strand being accumulated on a take-up reel, with the bed mounted at each end to the interior of a twisting frame by means of bearings such that the twisting frame may revolve about the stationary bed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
309 words
Apparatus for stranding wire comprising a support frame, a first shaft bearing means affixed to one end of said frame, and a second shaft bearing means affixed to the end of said frame opposite that at which said first shaft bearing means is located, separate shafts rotatably positioned in each of said shaft bearing means, said shafts being coaxial with each other and including strand passage means, spool cradle support bearing means which is rotatably affixed to the innermost ends of each of said shafts, a spool cradle means, including spool support means, adapted for rotatably supporting a single spool for containing a multiplicity of continuous filaments wound parallel thereon, with the axis of said spool normal to the axes of said shafts and substantially bisected by an imaginery flat plane that is normal to both said axis of said spool and the axes of said shafts, said cradle being moveably affixed at each of its ends to one of said spool cradle support bearing means, a twisting frame having at least one arm, each end of which is affixed to one of said shafts between said frame and said cradle, which arm includes strand guide means and is so dimensional and configured as to pass between said frame and said cradle as it moves upon rotation of said shafts, and finished strand take-up means, whereby a multiplicity of parallel filaments may be caused to pass concurrently from a spool supported by said spool support into the strand passage means of the one of said shafts and, as said frame rotates while said cradle remains unrotating, be twisted into a strand, passed along said guide means from one end to the other end of said arm, passed through the strand passage means in the other of said shafts, further twisted, and taken up through operation of said take-up means.
Claim 2
Dependent Claim
309 words
Apparatus for stranding wire comprising a support frame, a first shaft bearing means affixed to one end of said frame, and a second shaft bearing means affixed to the end of said frame opposite that at which said first shaft bearing means is located, separate shafts rotatably positioned in each of said shaft bearing means, said shafts being coaxial with each other and including strand passage means, spool cradle support bearing means which is rotatably affixed to the innermost ends of each of said shafts, a spool cradle means, including spool support means, adapted for rotatably supporting a single spool for containing a multiplicity of continuous filaments wound parallel thereon, with the axis of said spool normal to the axes of said shafts and substantially bisected by an imaginery flat plane that is normal to both said axis of said spool and the axes of said shafts, said cradle being moveably affixed at each of its ends to one of said spool cradle support bearing means, a twisting frame having at least one arm, each end of which is affixed to one of said shafts between said frame and said cradle, which arm includes strand guide means and is so dimensional and configured as to pass between said frame and said cradle as it moves upon rotation of said shafts, and finished strand take-up means, whereby a multiplicity of parallel filaments may be caused to pass concurrently from a spool supported by said spool support into the strand passage means of the one of said shafts and, as said frame rotates while said cradle remains unrotating, be twisted into a strand, passed along said guide means from one end to the other end of said arm, passed through the strand passage means in the other of said shafts, further twisted, and taken up through operation of said take-up means.
Claim 3
Dependent Claim
37 words
The apparatus described in claim 1 including guide plate means affixed to said spool cradle for guiding said filaments into a positionally desired spaced-apart configuration after leaving said spool and before entering into said strand passage means.
Claim 4
Independent Claim
20 words
The apparatus described in either of claims 1 or 2 wherein each of said arms is substantially semi-circular in shape.
Claim 5
Independent Claim
23 words
The apparatus described in either of claims 1 or 2 wherein said spool cradle means is removeably affixed to said shaft bearing means.
