Abstract
A method for forming a braided rope. Twisted yarns are first braided together to form braided strands, and the braided strands are then braided together to form the rope. The diameter of the individual twisted yarns is kept to a minimum, thereby reducing the number of twisting stages required to form the yarns and also permitting heat stretching treatment using existing systems. Moreover, in-line connections can be made within the individual strands using conventional braided rope splices, which both eliminates the need to use long splices during manufacture of the rope and enables individual strands to be spliced in the field to so as to repair snags, cuts, and other service damage without having to replace an entire length of the rope.
Claims14
A method of constructing a braided rope, said method comprising the steps of:
- twisting a multiplicity of fibers together so as to form a plurality of twisted yarns;
- heat stretching said twisted yarns;
- braiding a plurality of said twisted yarns together after heat stretching so as to form a plurality of braided strands;
- and
- braiding a plurality of said braided strands together so as to form said braided rope.
A braided rope, comprising:
- a multiplicity of fibers twisted together so as to form a plurality of twisted yarns;
- a plurality of said twisted yarns being braided together so as to form a plurality of braided strands, each said twisted yarn having been heat stretched prior to being braided together to form said braided strands;
- and
- a plurality of said braided strands being braided together so as to form said braided rope.
