Abstract:
A rope structure is formed by forming a sub-rope structure comprising a core and a jacket, twisting the sub-rope structure to form a twisted sub-rope structure, and forming the rope structure by braiding together a plurality of lengths of the twisted sub-rope structure.
Abstract:
A rope system comprising a rope structure comprising an intact portion comprising intact strands and a disassembled portion comprising loose strands. The loose strands are passed into an interior of the rope structure. Each loose strand is passed from the interior of the rope structure to the exterior of the rope structure adjacent to an associated intact strand. Each loose strand is extended along and wrapped around its associated intact strand at at least one wrap location.
Abstract:
A rope structure contains first and second sets of fibers. The first set of fibers is twisted together. The second set of fibers is twisted around the first set of fibers to form yarns. The first set of fibers is formed of a first material, the second set of fibers is formed of a second material, and elongation of the first set of fibers is different from elongation of the second set of fibers. Twists applied to the first and second fibers are such that loads on the rope structure are substantially evenly distributed across individual fibers. The yarns are combined to form strands in the form of a 3-strand rope. The strands are combined using a single braid process to form the rope structure defining a void space. The rope structure is formed such that lengths of fibers in the first and second sets are approximately the same.
Abstract:
A blended yarn comprises a plurality of first fibers and a plurality of second fibers. A coefficient of friction of the second fibers is greater than a coefficient of friction of the first fibers. Abrasion resistance characteristics of the second fibers are greater than abrasion resistance properties of the first fibers. A gripping ability of the second fibers is greater than a gripping ability of the first fibers. The plurality of second fibers are combined with the plurality of first fibers such that the first fibers extend along the length of the blended yarn and the second fibers do not extend along the length of the blended yarn at least a portion of the second fibers are engaged with and extend from the plurality of first fibers effectively to define surface characteristics of the blended yarn.
Abstract:
A rope structure comprising a core component comprising core fibers combine to form a first rope structure and a first cover component comprising first cover strands comprising first cover fibers within a first matrix material. The first cover strands are arranged around at least a portion of the core component.
Abstract:
A rope structure comprising a plurality of fibers combined to form a plurality of yarns which are in turn combined to form a plurality of strands. The plurality of strands are combined using a single braid process to form the rope structure defining a void space. At least one of the fibers, the yarns, and the strands are configured substantially to reduce a volume of the void space and thereby maintain a shape of the rope structure when the rope structure is under load.
Abstract:
A rope structure comprising a plurality of rope subcomponents, a plurality of bundles combined to form the rope subcomponents, a plurality of first yarns and a plurality of second yarns combined to form the bundles. In one embodiment, the first yarns have a tenacity of approximately 25-45 gpd and the second yarns have a tenacity of approximately 6-22 gpd. In another embodiment, the first yarns have a breaking elongation of approximately 2%-5% and the second yarns have a breaking elongation of approximately 2%-12%.
Abstract:
The present invention may be embodied as a line structure for use as a mud line assembly. In this case, the line structure comprises a plurality of strands, and each of the strands comprises a core portion, a jacket portion, and a barrier portion. The barrier portion is arranged between the core portion and the jacket portion to inhibit movement of contaminate material into the core portion.

Abstract:
A fire resistant rope and method of making the same. The fire resistant rope comprises a core formed of high tensile strength fibers and a jacket formed of high temperature resistant fibers, where the jacket covers the core. The core comprises a plurality of strands, where each strand comprises a plurality of yarns and each yarn comprises a plurality of high tensile strength fibers. The jacket comprises a plurality of strands, where each strand comprises a plurality of yarns and each yarn comprises a plurality of high temperature resistant fibers. Optionally, a fire retardant material may be applied to the rope.
