Abstract
A sheathed synthetic fiber rope includes concentric layers of load-bearing synthetic fiber strands, preferably of aramide fibers, with an outermost layer of strands having anchoring strands permanently fastened to a sheath extruded onto the outermost layer. The anchoring strands can be formed of weldable or vulcanizable material. Alternatively, a polyurethane jacket surrounding each of the outermost layer strands can be used to permanently fasten the sheath.
Claims14
A synthetic fiber rope comprising:
- a rope core formed of a plurality of load-bearing synthetic fiber strands laid together in layers;
- an outer layer of load-bearing synthetic fiber strands laid on said rope core and including anchoring means, said anchoring means being at least one of at least one anchoring strand laid between a pair of said outer layer strands and at least one anchoring fiber included in one of said outer layer strands;
- and
- a sheath surrounding said outer layer of strands and permanently fastened to said anchoring means.
