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.

A method for producing a rope, wherein fiber bundles are applied with a liquefied matrix material upstream of and/or at a twisting point to form fiber strands, and are embedded into the liquefied matrix material during stranding, by which fiber strands a fiber core of the rope is formed and wires or wire strands are wound about the fiber core. The matrix material of the fiber strands is hardened after the stranding, and the fiber strands are subsequently stranded directly with one another without further application to form the fiber core. Preferably the fiber strands are heated, during or after the stranding thereof to form the fiber core, so that the matrix material softens at least individual fiber strands, preferably all the fiber strands, another of the fiber strands is connected with the matrix material, and is subsequently hardened, forming an integral bond with one another.

Each intermediate layer is disposed between the core and the outer layer.

A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52).

A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.

Cable structures of security systems may include multiple subassemblies having different cut-resistant characteristics. One system includes, inter alia, a portable article, a support, and a length of a cable assembly extending between a first cable end coupled to the portable article and a second cable end coupled to the support, where the cable assembly includes a first cable subassembly extending along at least a portion of the length of the cable assembly, and a second cable subassembly extending along at least the portion of the length of the cable assembly and adjacent to the first cable subassembly, and where the first cable subassembly includes a first cut resistant characteristic and the second cable subassembly includes a second cut resistant characteristic that is different than the first cut resistant characteristic.

A method for producing a strand or cable, in which fibers and/or wires are twisted at a twisting point to form the strand or cable. The fibers and/or wires are coated with a liquefied matrix material before and/or at the twisting point and are embedded in the matrix material during twisting. The fibers and/or wires are immersed in the matrix material before and/or at the twisting point and the formed strand or the formed cable is cooled after the twisting in order for the matrix material to solidify, preferably by air or in a cooling liquid, for example water.

The present invention relates to a rope for an elevator. The rope for the elevator comprises: a center strand formed by twisting a plurality of wires; inner layer strands formed by twisting the plurality of wires and arranged along the outer periphery of the center strand; and outer layer strands formed by twisting the plurality of wires and arranged along the outer periphery of the inner layer strands, wherein ten of each of the inner layer strands and the outer layer strands are prepared, the diameter of the center strand, the diameter of the inner layer strand and the diameter of the outer layer strand are respectively 0.33-0.35 times, 0.13-0.15 times and 0.22-0.24 times as large as the diameter of a first imaginary circle circumscribed around the outer layer strands, and a fill factor is 64-67%.

Disclosed is a steel wire rope for conveyor belts. The steel wire rope includes a central steel wire, a steel wire layer externally wound on the central steel wire, and a plurality of external steel wire strands. Each external steel wire strand includes a core steel wire and N external steel wires. The central steel wire, the steel wire layer externally wound on the central steel wire, and the plurality of external steel wire strands are wound into a steel wire rope for conveyor belts in one step. The steel wire layer is externally wound on the outer side of the central steel wire, the external steel wire strands are wound to wrap the outer side of the steel wire layer, and the external steel wire strands are in line contact with the steel wire layer.

With a wire rope comprising at least one plastic core (11) and a number of wire strands (15) twisted around the latter a helical groove (20) is respectively produced by machining around the periphery of the plastic core (11) for each wire strand (15). The cross section of these helical grooves (20) is respectively matched to the outside diameter of the wire strands (15). The plastic core (11) is provided with the helical grooves (20) for receiving the wire strands (15) by this machining directly before the wire strands (15) are wound onto said core. By thus forming the wire rope by means of this machining in order to produce helical grooves of the plastic core, optimal guiding of the wire strands in the twisted state is achieved, and so overall there are improvements to the properties of the wire rope.
