Abstract:
A wire rope is provided which has an independent wire rope core (IWRC) covered by a plastic jacket. Outer strands are laid on this plastic jacket and wormings or spacers extend from the plastic jacket in between the outer strands to form gaps between the outer strands. Another jacket is provided over the outer strands which also fills the gaps between the outer strands. Both the IWRC and the outer strands are preferably lubricated. A method is also disclosed for manufacturing such wire rope.
Abstract:
An inner layer rope has a plurality of inner layer strands, in which a plurality of steel wires are twisted together, with an elevator rope for suspending a car of an elevator apparatus. An inner layer cladding made of a resin covers a periphery of the inner layer rope. An outer layer is formed on a peripheral portion of the inner layer cladding. The outer layer has a plurality of outer layer strands in which a plurality of steel wires are twisted together. An outer layer cladding made of a high-friction resin material covers the periphery of the outer layer.
Abstract:
Methods of making electrical conductors by twisting a plurality of strands to form a bundle, winding the bundle to form a coil, fusing some of the strands together, optionally drawing the bundle prior to winding and fusing utilising materials and coatings disclosed.
Abstract:
Wires or strands are led through a die. The wires or strands are centrally supported against inward collapse, by a mandrel coaxial with the die, until the wires or strands are in mutual contact. The wires or strands can be compressed by the die, and the central support of the wires or strands may be maintained during at least the start of compression. Tubular strand can be produced which, in transverse section has a central circular void, and in which adjacent wires abut along interfaces which are straight lines in transverse section.
Abstract:
A multi-wire member in which the outer layer comprises alternate base and oversize wires wherein the oversize wires have been deformed into interlocking engagement with each other and with respect to the wires comprising the next underlying layer of the member to produce a smooth and substantially continuous outer surface.
