Abstract:
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.

The invention is useful for thermal management in a variety of applications in such as, for example, automotive, building, packaging, garments, and footwear.
Abstract:
A method of forming a belt for suspending and/or driving an elevator car includes arraying a plurality of tension elements longitudinally along a belt and interlacing a plurality of warp fibers and a plurality of weft fibers with the plurality of tension elements to form a composite belt structure. A coating is applied to at least partially encapsulate the composite belt structure. The coating includes a base coating material and at least one additive mixed with the base coating material to improve an operational characteristic of the belt.
Abstract:
Hybrid rope (20) comprising a core element (22) containing high modulus fibers surrounded by at least one outer layer (24) containing wirelike metallic members (26). The core element (22) is coated (23) with a thermoplastic polyurethane or a copolyester elastomer, preferably the copolyester elastomer containing soft blocks in the range of 10 to 70 wt %. The coated material (23) on the inner core element (22) is inhibited to be pressed out in-between the wirelike members (26) of the hybrid rope (20) and the hybrid rope (20) has decreased elongation and diameter reduction after being in use.
Abstract:
Disclosed is a high traction synthetic rope comprising a braided sheath adhered to a strength member by means of a first synthetic portion and portions of material adhered to the outside surface of the braided sheath by means of a second synthetic portion, where the portions of material are formed of a substance that differs from a substance mainly forming the second synthetic portion and also preferably exhibits greater friction when wet and measured on an iron surface than does the substance mainly forming the second synthetic portion.
Abstract:
A load bearing assembly (100) for use in elevator system wherein the load bearing assembly (100) comprises at least one steel rope (102) and a jacket (110) surrounding this at least one steel rope (102). The jacket (110) comprises at least one layer of a thermoplastic elastomer comprising polymer particles (112). The polymer particles (112) have a molecular weight higher than 0.5*10 6 g/mol.

Abstract:
The invention relates to a method for producing a strand or cable (20), in which fibres (2) and/or wires are twisted on a twisting point (3) to form the strand or cable (20). According to the invention the fibres (2) and/or wires are coated with a liquefied matrix material (4) in front of and/or at the twisting point (3) and are embedded in the matrix material (4) during twisting. The fibres (2) and/or wires are immersed in the matrix material in front of and/or at the twisting point (3) and the formed strand or the formed cable (20) are cooled after the twisting in order for the matrix material (4) to solidify, preferably by air or in a cooling liquid, for example water. The invention further relates to a device for carrying out the method and to a cable which can be produced by means of the method.
