Abstract
Abstract A braided rope construction comprising a plurality of singles yarns twisted together to form a plurality of plied yarns which are then braided, with the helical angle of twist of the singles yarn within their respective plied yarn being equal and opposite to the helical angle of the plied yarns in the braid, whereby the singles yarns extend substantially parallel to the axis of said rope.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
A braided rope construction having a cover comprising a plurality of singles yarns formed from a plurality of filaments twisted together, said singles yarns twisted together to form a plurality of separate plied yarns, a plurality of said plied yarns longitudinally bundled together in substantially parallel, non-twist relation to form a strand, a plurality of said strands being braided together with each of the singles yarns therein being disposed at a helical angle that is equal and opposite to the helical angle of said plied yarns in said braid, whereby said singles yarns extend substantially parallel to the axis of said rope.
Claim 2
Dependent Claim
102 words
A braided rope construction having a cover comprising a plurality of singles yarns formed from a plurality of filaments twisted together, said singles yarns twisted together to form a plurality of separate plied yarns, a plurality of said plied yarns longitudinally bundled together in substantially parallel, non-twist relation to form a strand, a plurality of said strands being braided together with each of the singles yarns therein being disposed at a helical angle that is equal and opposite to the helical angle of said plied yarns in said braid, whereby said singles yarns extend substantially parallel to the axis of said rope.
Claim 3
Dependent Claim
38 words
The rope of claim 1 further characterized in that the direction of twist of the filaments in said singles yarns is opposite to the direction in which said singles yarns are twisted to make up said plied yarns.
Claim 4
Dependent Claim
20 words
The rope of claim 1 further characterized in that said rope comprises a longitudinally extending core positioned within said braid.
Claim 5
Dependent Claim
14 words
The rope of claim 3 further characterized in that said core is a braid.
Claim 6
Dependent Claim
16 words
The rope of claim 4 further characterized in that said braided core comprises braided singles yarns.
Claim 7
Dependent Claim
16 words
The rope of claim 4 further characterized in that said braided core comprises braided plied yarns.
Claim 8
Independent Claim
108 words
The method of making a braided rope construction comprising the following steps: (a) twisting together a plurality of individual filiaments to form a plurality of singles yarns; (b) twisting together a plurality of said singles yarns to form a plurality of plied yarns; (c) laying a plurality of said plied yarns together in substantially parallel, non-twist relation to form strands; and (d) braiding said strands together so that the helical angle of said plied yarns in said braid is equal and opposite to the helical angle of said singles yarns in their respective plied yarns, whereby said singles yarns extend substantially parallel to the axis of said rope.
Claim 9
Independent Claim
108 words
The method of making a braided rope construction comprising the following steps: (a) twisting together a plurality of individual filiaments to form a plurality of singles yarns; (b) twisting together a plurality of said singles yarns to form a plurality of plied yarns; (c) laying a plurality of said plied yarns together in substantially parallel, non-twist relation to form strands; and (d) braiding said strands together so that the helical angle of said plied yarns in said braid is equal and opposite to the helical angle of said singles yarns in their respective plied yarns, whereby said singles yarns extend substantially parallel to the axis of said rope.
Claim 10
Dependent Claim
26 words
The method of claim 7 further characterized in that the direction of twist in step (a) is opposite to the direction of twist in step (b).
Claim 11
Dependent Claim
33 words
The method of claim 7 further characterized in that the braiding operation of step (c) is performed at a pick ratio of greater than 4 so as to form a relatively loose braid.
Claim 12
Dependent Claim
28 words
The method of claim 7 further comprising the step of forming an elongated core, and positioning said core so that the braid of step (c) is formed thereover.
Claim 13
Dependent Claim
13 words
The method of claim 10 further comprising the step of braiding said core.
