An apparatus for producing an assembly of filamentary elements that are wound together in a helix includes a twisting device, a preforming device, and an assembling device. The twisting device is structured to twist at least first and second filamentary elements individually, such that each filamentary element is twisted separately from another filamentary element, to produce at least first and second twisted filamentary elements. The preforming device, which is arranged downstream of the twisting device, is structured to preform each of the twisted filamentary elements individually into separate preformed helixes, to produce at least first and second preformed helixes. The assembling device, which is arranged downstream of the preforming device, is structured to assemble the preformed helixes into an assembly.

A strand (20) for a cable bolt (14) comprises a plurality of metallic elongated members (22, 24) twisted together. At least one of the elongated members has a corrosion resistant coating (54) and surface deformation, so as to improve the bodig efficiency and the anchorage of the strand.

A cord rubberized in situ (C). Internal layer of the cord (CT1) comprises N1 internal thread(s). External layer of the cord (CT3) comprises N3 external threads wound helically around the internal layer of the cord. Rubber composition (20) is positioned between the internal layer of the cord and the external layer of the cord, and comprises a compound of formula (I) or a salt of this compound:

##STR00001##

in which: each R1, R2 and R3 group represents, independently of one another, an alkylene, arylene, arylalkylene, alkylarylene or cycloalkylene group, each X.sub.1 and X.sub.2 group represents, independently of each other, COOH, CONHOH, SOOH, PO(OR)(R) or PO(OR)(OR) with R and R representing, independently of each other, hydrogen or an alkyl group, and X.sub.3 comprises at least one COOH, CONHOH, SOOH, PO(OR)(R) or PO(OR)(OR) group with R and R representing, independently of each other, hydrogen or an alkyl group.

An operating wire has a multi-twisted structure constituted by twisting side strands, each formed by twisting element wires together around a core strand. A side element wire of the side strand faces the outside of the operating wire in the radial direction at a site located on the outer circumference of the operating wire and has a flattened surface where a flat portion provided in a portion of the side element wire in the circumferential direction extends in the X axis direction, the length in the X axis direction of the flattened surface being 4.8-11.0 times the diameter of the side element wire, and the pitch magnification of the side strand being 7.0-12.0 times the diameter.

A belt for suspending and/or driving an elevator car includes a tension member extending along a length of the belt, the tension member including a plurality of fibers bonded in a first polymer matrix, the plurality of fibers extending parallel to and discontinuous along a length of the belt and arranged with one or more lengthwise extending gaps between lengthwise adjacent fibers. A jacket substantially retains the tension member. A method of forming a tension member for an elevator system belt includes arranging a plurality of fibers into a fiber bundle. The plurality of fibers extend parallel to a length of the belt and have one or more lengthwise extending gaps between lengthwise extending fibers. The plurality of fibers is bonded to a first polymer matrix.

A wire rope includes a strand that is formed by winding a plurality of metal wires. The strand includes a core wire and side wires. Each of the side wires is arranged on an outer periphery of the core wire. In a transverse section of the strand, each of the side wires includes end portions positioned at opposite ends in a circumferential direction of the core wire. Each of the end portions includes a contact portion in contact with an end portion of an adjacent side wire, and a non-contact portion not in contact with the adjacent side wire. A Vickers hardness of the contact portion is higher by 1% or more than a Vickers hardness of the non-contact portion. A surface roughness Ra of an outer peripheral surface of each of the side wires is 0.10 m or less.

The invention refers to a rope (3) made of a textile fiber material, comprising a rope core (6) and a sheath (7) surrounding the rope core (6), wherein the rope (3) comprises at least one antistatic multifilament yarn (5) or antistatic monofilament that is located in the rope core (6), in the sheath (7), in an intermediate sheath (8) located between the rope core (6) and the sheath (7) and/or in a reinforcement located between the rope core (6) and the sheath (7), wherein the antistatic monofilament or individual filaments (12) of the antistatic multifilament yarn (5) each comprise a conductive fiber core (13) sheathed with a non-conductive plastic sheath (14), and the at least one antistatic multifilament yarn (5) or antistatic monofilament is twisted with a twine (16) or yarn of a different material, wherein the other material of the twine (16) or yarn is preferably UHMWPE or PES.
