A conveyor belt includes a first outer sheet disposed on a loadbearing side of the conveyor belt, a second outer sheet disposed on a drive side of the conveyor belt, and an embedded tension-member system disposed between the two sides, which is in the form of cords running parallel in the longitudinal direction of the conveyor belt. The tension-member system includes steel and, prior to vulcanization of the conveyor belt, an expandable coating which, after vulcanization of the conveyor belt, has a pore structure provided to at least portions of the tension-member system. The sheets are formed from a polymeric material with resilient properties. In some aspects, the volume of the coating after vulcanization is from 30 to 5000% higher than prior to vulcanization. The coating may contain at least one of a blowing agent and/or microbeads.

A method of manufacturing an escalator handrail which has a composite material including a metallic steel wire and a thermoplastic resin, said metallic steel wire having a center elemental wire and a plurality of strands placed so as to surround the center elemental wire, including: a preheating step of heating the metallic steel wire; a composite-material forming step of integrating the metallic steel wire heated in the preheating step with the thermoplastic resin in a molten state to thereby form the composite material; and a cooling step of cooling the composite material formed in the composite-material forming step.

A longitudinal element produced with a core made of high-strength fibers and at least one metal casing, preferably steel, surrounding this core. In this way, there is the significant advantage that these high-strength fibers, which are very lightweight in relation to their strength, are protected in a number of ways, namely against humidity, moisture, UV light and other environmental influences. In addition, the metal casing provides the fibers with protection against transverse loads. In this way, all the high-strength properties of the traction or suspension means are maintained over a sustained period.

The invention relates to a method for filling in a tension member in particular for conveyor belts, in particular a tension member which is configured as a steel cable. The method is intended to allow the full penetration of the tension member structure. Here, the method contains at least the following method steps: —introducing the individual wires (2, 2′, 2″, 2′″, 2″″) of the strand (5) into the stranding head (1) of a stranding machine (10) and —partially or fully applying at least one coating agent to at least 50% of the individual wires (2, 2′, 2″, 2′″, 2″″) of the strand (5) prior to the twisting of the individual wires (2, 2′, 2″, 2′″, 2″″) to form a strand (5) or simultaneously with the twisting of the individual wires (2, 2′, 2″, 2′″, 2″″) to form a strand (5) and —twisting the individual wires (2, 2′, 2″, 2′″, 2″″) to form a strand (5), wherein at least 50% of the individual wires (2, 2′, 2″, 2′″, 2″″) have been provided with at least one coating agent, and —making a cable from at least one strand (5).

The method for manufacturing an individually sheathed strand comprises: conveying a group of metal wires through a die; upstream of the die, applying a first filler product to at least a first portion of the strand; upstream of the die, applying a second filler product to at least a second portion of the strand distinct from the first portion; and extruding a plastic around the group of metal wires passing through the die, so as to envelop the group of metal wires covered with the first and second filler products in a continuous sheath formed of the extruded plastic. The second filler product has greater adhesion to the group of metal wires than the first filler product.

A high-strength fiber bundle sufficiently impregnated with a thermoplastic resin, without impairing mechanical strength. A high-strength fiber composite cable is produced by impregnating a bundle of carbon fibers with a matrix resin. The matrix resin is obtained by mixing, with a thermoplastic resin, such as polyphenylene sulfide, an oligomer having a weight-average molecular weight of less than 10,000, obtained by causing a reaction between an organic compound having a phenolic hydroxyl group and an organic compound having a glycidyl ether group. The matrix resin, which has a viscosity low in comparison with that of the thermoplastic resin serving as a base material, readily impregnates the bundle of carbon fibers with certainty.
