Abstract:
A steel cord adapted for the reinforcement of elastomers includes: a core steel filament with a diameter dc and coated with a polymer, six intermediate steel filaments with a diameter di smaller than or equal to dc, the intermediate steel filaments being twisted around the core steel filament, ten to eleven outer steel filaments with a diameter do, smaller than or equal to di wherein these outer steel filaments are twisted around the intermediate steel filaments, and the outer steel filaments are preformed in order to allow rubber penetration inside the cord. The core steel filament, the intermediate steel filaments, and the outer steel filaments all have a tensile strength of at least 2600 MPa. The cord has an outer diameter D according to the following formula: D≦dc+2×di+2×do+0.1 mm, wherein all diameters are expressed in millimeters (mm).

Abstract:
A wire rope which has an independent wire rope core (IWRC) and outer strands laid around the core. This wire rope has an improved fatigue life when the outer wires of the core and of the outer strands are galvanized. The wire rope may be either fully or partially impregnated with plastic, if desired.
Abstract:
An elevator rope includes an inner layer rope having inner layer strands in which steel wires are twisted together for suspending a car of an elevator apparatus. An inner layer cladding made of a resin covers a periphery of the inner layer rope. A outer layer on a peripheral portion of the inner layer cladding has outer layer strands in which steel wires are twisted together. An outer layer cladding made of a high-friction resin material covers the periphery of the outer layer.
Abstract:
A steel cord according to the invention comprises a metal core strand (11) and adjacent layer of steel elements (13). Between metal core strand (11) and adjacent layer of steel elements (13), a polymer layer (16) with a minimum thickness of more than 0.02 mm is provided. These steel cords are to be used to reinforce off-the-road tires or conveyor belts.
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:
The wire rope of this invention has at most 18 outer strands and an independent wire rope core, with the strands of the core being laid in the opposite direction to the outer strands of the rope, and a nylon jacket is provided between the core and the outer strands of the wire rope.
Abstract:
This invention provides a composite wire rope comprising a plurality of outer strands laid helically about a helically stranded core. The core is comprised of high strength synthetics, such as polyamide or polyolefin materials to form a unitized lay central member. The method for forming the rope comprises the steps of twisting high strength synthetic monofilament yarns into core elements to provide a high degree of stability and overall tensile strength. Each such element is helically laid in a single operation to form the finished core. Lubricant may be applied and subsequently a protective jacket of steel, natural or synthetic material may be provided to encapsulate the core and lubricant. The rope structure is completed by helically laying a plurality of outer strands about the core.
Abstract:
A cable comprises at least one layer of strands (10) with each strand covered with an individual sheath (20) of rubber or plastics material. The sheaths are so shaped (16, 17, 18) that the sheaths of adjacent strands interlock. This provides a layer in which the strands have a generally fixed spatial relationship both to each other and within the cable. This reduces inter-strand forces, so increasing cable life, and also provides a dimensionally stable cable.

PCT No. PCT/GB78/00019 Sec. 371 Date June 5, 1979 Sec. 102(e) date June 1, 1979 PCT Filed Oct. 3, 1978 PCT Pub. No. W079/00182 PCT Pub. Date Apr. 19, 1979The invention relates to wire ropes.There is disclosed a wire rope comprising a plurality of strands (4-12) twisted together with each strand (4-12) being individually covered by a respective sheath (16) of rubber or rubber substitute. Each strand (4-12) comprises a plurality of wires (14) twisted together with the direction of twist of at least the outer wires (14) in each strand (4-12) being opposite to the direction of twist of at least the outer wires (14) in the strands (4-12) adjacent to it, the rope having an outer covering sheath (18) of rubber or rubber substitute.In this way, the wires (14) of adjacent strands (4-12) do not cross each other, and stress on them is reduced.
