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:
A safety elastic rope includes an elastic outer tubular rope having two longitudinally opposite first fixing ends, and an elastic inner rope inserted into the outer tubular rope and having two longitudinally opposite second fixing ends. The inner rope is more elastic than the outer tubular rope, and has substantially the same length as the outer tubular rope. The second fixing ends are connected respectively to the first fixing ends.
Abstract:
A synthetic rope for an elevator having improved resistance to compression and abrasion is provided and comprises a plurality of strands forming layers of the rope, each strand formed from a plurality of pre-twisted strands made from high modulus synthetic filaments. One or more of the strands or layers of strands may be impregnated with a lubricant, such as polytetrafluoroethylene, to reduce the abrasion among the strands and substrands, and increase the service life of the rope. The exterior of the rope may be covered by a jacket that provides for traction with the drive sheave. An elevator system comprising the claimed rope is also provided.
Abstract:
A unique rope for use in commercial fishing comprising floating and sinking portions. The sinking portion has blended yarns made up of a blend of first and second non-metallic synthetic filaments in proportions to yield a sinking rope portion having a specific gravity greater than one. The sinking rope portion comprises strands having yarns of substantially the same diameter. The floating portion of the rope is formed by replacing selected ones of the blended yarns in each strand with yarns formed of a material having a specific gravity of less than one. The replacement yarns and the blended yarns are of the same diameter to enhance the integrity and strength of the rope. The yarns omitted from the sinking section and replaced with the yarns having a specific gravity less than one are terminated at staggered intervals along the rope and their replacement yarns are inserted at like staggered intervals forming a merged region between the sinking and floating portions having a tensile strength which is equivalent to the tensile strength of the sinking and floating portions. The rope material sensitive to ultraviolet radiation is surrounded and thus protected by the material resistant to ultraviolet radiation. The ultraviolet sensitive material may also be treated with a stabilizer material which enhances resistance to ultraviolet radiation. A method is also disclosed for producing the floating/sinking rope.
