Abstract:
A wire rope (10, 20), comprising: a core (12, 22), a plurality of outer strands (18, 28) and a plurality of separator strands (17, 27) laid on said core (12, 22), and a first plastic jacket (19) around said plurality of outer strands (18, 19) and said plurality of separator strands (17, 27), wherein said plurality of separator strands (17, 27) extend from said core (12, 22) and in-between each pair of said plurality of outer strands (18, 28) so as to produce and maintain gaps between said pair of said plurality of outer strands (18, 28). Plastic impregnation of the wire rope (10, 20) can be ensured due to the separator strands/17, 27).
Abstract:
A cord obtained by twisting a plurality of strands each composed of a plurality of filaments is provided. A circumferential surface of the filament is coated with unvulcanized rubber to improve rubber intrusion, thereby improving corrosion resistance and suppressing twisting-loss.
Abstract:
A wire rope including at least one metal wire and at least one fluoropolymer fiber. Preferably, the fluoropolymer fiber is present in an amount less than about 25 weight %, and in alternative embodiments less than 20 weight %, 15 weight %, 10 weight %, and 5 weight %. The fluoropolymer fiber is preferably PTFE, and most preferably expanded polytetrafluoroethylene (ePTFE). The wire rope is useful in tensioned and bending applications.
Abstract:
In order to improve visibility and hence to reduce the risk of accidents, a rope, for example a wire rope, is equipped with a number of luminous elements. A luminous element may in this case assume the position of a wire or of a braid, may be integrated in an insert, or may be guided in the spaces between wires or braids and preferably within the theoretical rope circumference. The luminous element may also itself be composed of luminous elements which are twisted together, are twisted or are laid. For strain relief, the luminous elements may be equipped with a reinforcement in the form of a strand, or with a mesh. The luminous element is intended to be connected to a source. In the state when it is fed, the luminous element is actively luminous. Owing to the improved visibility, rope lights may be used not only for a safety function but also for an aesthetic appearance.
Abstract:
A reinforcement for a building works structure comprising an assembly of solid wires. The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath made of plastic material enclosing the bundle and providing it with cohesion.
Abstract:
A wire rope is provided having a central core strand about which are wound outer strands. Non-linear spacer wires are present in the gaps between outer strands to assure the uniformity of such gaps and provide passageways from the interior to the exterior of the wire rope. A coating, usually of a suitable thermoplastic, is extruded into such rope to extend continuously from the core and between adjacent outer strands and through the passageways.
Abstract:
A wire rope for a running wire, has a core rope, a plurality of side strands arranged at an outer periphery of the core rope to be twisted together therewith, and a resin spacer interposed between the side strands, the core rope including a core rope main body composed of a plurality of wires and a resin coating layer outwardly surrounding the core rope main body so that the resin coating layer separates the core rope main body from the side strands, each of the side strands being composed of a plurality of further wires, and the resin spacer being provided with contour corresponding to an outer layer of the further wires of the side strands and extending between the wires of the outer layer of the side strands.
Abstract:
The invention includes a composite cable having a plurality of strands (10, 12) stranded around a composite synthetic core (5) with a concentric structure. The core (5) has a nucleus (11) formed by a bundle of parallel synthetic fibers extending along the cable longitudinal direction, and of a compact thermoplastic sheath (13) enclosing the nucleus (11) and serving as winding support for the strands.
