Abstract
A rope and a method of constructing the rope. The rope may be of 12×12 braided construction and include a core for its length. The rope includes a plurality of primary strands, and each of the primary strands includes a plurality of fibers which may be made of a high-friction material. The rope also includes a secondary strand surrounded by the plurality of primary strands. The secondary strand includes a plurality of fibers which may be made of a low-friction material.
Claims24
A rope comprising:
- a plurality of primary strands each including a plurality of fibers comprising a high-friction material, the plurality of primary strands defining an outer surface and a longitudinal center passageway of the rope;
- and
- a secondary strand disposed within the longitudinal center passageway of the rope and including a plurality of structurally stable fibers, the material of the plurality of fibers of the secondary strand including a non-flowable, low-friction material.
A rope comprising:
- a plurality of outer strands together defining an outermost surface of the rope and a longitudinally-extending center passageway of the rope, the plurality of outer strands each including a plurality of fibers, the plurality of fibers including a high-friction material defining a first coefficient of friction with itself;
- a core strand disposed within the longitudinally-extending center passageway of the rope and separated from the outermost surface by at least one of the plurality of outer strands at all positions along a length of the rope, the core strand including a plurality of structurally stable fibers, the plurality of structurally stable fibers including a non-flowable, low-friction material defining a second coefficient of friction with the high-friction material, the second coefficient of friction being less than the first coefficient of friction.
A rope comprising:
- twelve outer strands together defining a longitudinally-extending center passageway of the rope, the twelve outer strands being braided in a single braid pattern, each of the twelve outer strands including twelve sub-strands braided in a single braid pattern, and each of the sub-strands including a plurality of synthetic fibers;
- and
- a core strand disposed in the longitudinally-extending center passageway over the length of the rope, the core strand including a plurality of fibers.
