Abstract
Abstract A stabilized parallel wire strand is made by drawing a plurality of wires through a forming die from a plurality of rotatable payoffs each of which is arranged to rotate in a direction opposite to at least one other pay-off while clamping the wires at their leading ends to prevent rotation of the wires about their axes and finally binding the wires together with a resilient binding at intervals along the length of the strand. After binding the strand can be immediately reeled by actively or passively rotating the strand periodically about its longitudinal axis in alternate clockwise and counterclockwise directions as it passes onto a reel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
A method of forming a parallel-wire strand comprising: a. drawing a plurality of wires from a plurality of rotatable pay-off means, substantially each one of which is arranged to rotate in a direction opposite to at least one other pay-off means, b. through a forming-die means, c. while firmly securing a preceding portion of the strand to maintain the wires in the same relationship as their respective pay-off means with the natural curvature of substantially each wire being opposed to the natural curvature oF another wire, and d. binding the strand at intervals to maintain its integrity.
Claim 2
Independent Claim
97 words
A method of forming a parallel-wire strand comprising: a. drawing a plurality of wires from a plurality of rotatable pay-off means, substantially each one of which is arranged to rotate in a direction opposite to at least one other pay-off means, b. through a forming-die means, c. while firmly securing a preceding portion of the strand to maintain the wires in the same relationship as their respective pay-off means with the natural curvature of substantially each wire being opposed to the natural curvature oF another wire, and d. binding the strand at intervals to maintain its integrity.
Claim 3
Dependent Claim
62 words
A method of forming a parallel-wire strand according to claim 1 wherein e. the preceding portion of the strand is secured in a hexagonal clamping means whereby the individual wires are all firmly gripped by clamping pressure exerted on the sides of the strand, and f. the parallel-wire strand is drawn through a hexagonal roller die means to form a hexagonal strand.
Claim 4
Dependent Claim
100 words
A method of forming a parallel-wire strand according to claim 2 wherein g. substantially one-half of the wires are drawn from left-handed wire coils on rotatable pay-off means rotating in one direction, h. The remainder of the wires are drawn from right-handed wire coils on rotatable pay-off means rotating in the opposite direction, i. the wires from the left-handed coils are conducted together through fairleads and lay-plates to one-half of the hexagonal roller-die forming means, and j. the wires from the right-handed coils are conducted together through fairleads and lay-plates to the other half of the hexagonal roller-die forming means.
Claim 5
Dependent Claim
127 words
A method of forming parallel-wire strand according to claim 1 additionally comprising the improvement whereby the strand can be continuously formed and reeled comprising: e. drawing the strand through a hexagonal die means by the action of a dynamic clamp which both draws the strand and effectively clamps the strand subsequent to its formation in the die means, f. binding the strand with strong, resilient binding means to maintain its integrity, g. reeling the strand onto a large-diameter reel subsequent to passing through the dynamic clamp, and h. facilitating alternate rotation of the strand about its own axis between the dynamic clamp and the reel, and on the reel, whereby the distortions and stresses of bending the parallel-wire strand are rendered harmless as the strand is reeled.
Claim 6
Independent Claim
120 words
A method of continuously forming and reeling parallel-wire strand comprising: a. drawing a plurality of wires through a hexagonal die forming means to form a hexagonal strand, b. binding the strand at intervals with strong, resilient binding material to maintain its integrity after it passes through said die forming means, c. drawing said hexagonal strand through a dynamic hexagonal clamp means beyond the die forming means, d. reeling the strand upon a large-diameter reel beyond the dynamic clamp means, and e. facilitating alternate rotation of the strand about its own axis between the dynamic clamp and the reel, and on the reel, whereby the distortions and stresses of bending the parallel-wire strand are rendered harmless as the strand is reeled.
Claim 7
Independent Claim
120 words
A method of continuously forming and reeling parallel-wire strand comprising: a. drawing a plurality of wires through a hexagonal die forming means to form a hexagonal strand, b. binding the strand at intervals with strong, resilient binding material to maintain its integrity after it passes through said die forming means, c. drawing said hexagonal strand through a dynamic hexagonal clamp means beyond the die forming means, d. reeling the strand upon a large-diameter reel beyond the dynamic clamp means, and e. facilitating alternate rotation of the strand about its own axis between the dynamic clamp and the reel, and on the reel, whereby the distortions and stresses of bending the parallel-wire strand are rendered harmless as the strand is reeled.
