A drive cable for actuating a vehicle element movable relative to a vehicle body is provided, the drive cable having a cable body having a cable core around which a coil following a helical line is coiled, the coil serving to engage with a gear wheel, the cable body being provided with a cable sheath. The cable sheath is glued to the coil.

An inline method for producing a spring strip profile (1) for a slatted frame that comprises at least one core strand (2) formed by a fiber-reinforced plastic and at least one thermoplastic cover layer (3) surrounding the core strand (2), comprises at least the following steps: joining multiple fibers, threads and/or filaments to form a fiber bundle (2.1); impregnating the fiber bundle (2.1) with a thermally activatable reaction resin; molding the outer contour of the fiber bundle (2.1) impregnated with the reaction resin; thermally activating the reaction resin (2.1) to form a cured core strand; introducing the core strand (2) into an extruder head (110); applying thermoplastic melt in the extruder head (110) to form the cover layer (3) on the spring strip profile (1); and cooling and calibrating the spring strip profile (1) in a cooling and calibrating device (111, 112, 113). The outer contour of the fiber bundle (2.1) is wrapped around, in a winding machine (105), by at least one thread or filament (2.2) supplied laterally in relation to the fiber bundle in at least one position and orientation, and, in a heating section (106), before the core strand (2) is introduced into the extruder head (110), at least a partial curing of the reaction resin is achieved, at least in the wrapped outer layer of the fiber bundle (2.1).

A method of forming a fiber-reinforced molding compound. The method includes establishing a melt stream of a source material including a first polymeric material having a first melt temperature in an extruder and dosing a composite material into the melt stream. The composite material includes pre-impregnated reinforcing fibers comprising reinforcing filaments and a second polymeric material having a second melt temperature greater than the first melt temperature. The composite material has at least 30% of the reinforcing filaments protected by the polymeric material such that the polymeric material surrounds each filament completely forming a barrier between it and an adjacent filament in the at least 30% of the filaments. The temperature of the melt stream at dosing is below the second melt temperature. The method includes forming a molding compound from the source and composite materials. The method includes dispensing the molding compound to produce a part.

A method and a device for producing fibre-reinforced plastic mouldings, using coated fibre strands. For the coating of the fibre strands, an air flow of ionised air is produced and guided through a Venturi nozzle. Powder from a storage container is taken by means of a screw conveyor and supplied to the Venturi nozzle, a flow of a powder-air mixture being present or forming behind the Venturi nozzle in the direction of flow. This stream is introduced into a chamber and fibre strands that are earthed or ionised unlike the powder are passed through the chamber and through the powder-air mixture flowing through the chamber, powder particles being deposited on the fibre strands. The fibre strands guided out of the chamber therefore have a coating, and the fibre strands coated in this way are supplied to a plasticising device of an injection moulding machine or an extrusion machine.

A method of manufacturing a workpiece includes heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven. A second fiber reinforced thermoplastic material is heated in an extruder. The second fiber reinforced thermoplastic material is extruded from the extruder, within the oven, to form an extrudate. The extrudate is positioned on the pre-formed blank of the first fiber reinforced thermoplastic material, within the oven, to form a composite blank. The extrudate may be formed into a shape before being positioned onto the pre-formed blank, after being positioned onto the pre-formed blank. The composite blank may then be transferred to a final shaping station.

A rubber-coating device for a steel wire is provided with: a heating device for heating water to a specified temperature range; heat transfer rollers, which contact the steel wire and inside which a water passage is formed; and an extruder for coating rubber on the steel wire that is heated by the heat transfer rollers.

An article may include a carcass or jacket, and at least one composite member arranged within the carcass or jacket for inhibiting longitudinal stretch of the article. The composite member may include a plurality of fibers arranged in a polymeric binder, the polymeric binder bonding the composite member to the carcass or jacket. The carcass or jacket may be formed substantially of rubber or thermoplastic elastomer. The plurality of fibers may include fibers formed substantially from at least one of S-glass, aramid and carbon fiber. The polymer binder may be formed substantially of a thermoplastic material or of a thermoset material. In manufacturing of the article, the carcass or jacket may be extruded to surround the composite member. The article may be a handrail or an elevator belt.
