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 of the fiber strands, preferably all the fiber strands, softens and connects with the matrix material of another of the fiber strands, and is subsequently hardened, forming an integral bond with one another.
A wire cable and a device and method for producing the wire cable, wherein a core strand is compacted and then braid strands are stranded on the core strand. The core strand is hammered before stranding of the braid strands in order to smooth the surface thereof. A plastic layer is applied to the core strand before stranding of the braid strands. The braid strands are pressed into the plastic layer while the plastic layer is heated. The core strand is a core cable and the braid strands are strands of the wire cable or the core strand is a heart strand and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable is obtained by hammering the core strand in order to smooth it than by compacting a core strand with a roller compressor.
A method and device for producing a rope, in particular a wire rope, a fiber rope or a rope having wire and fibers, wherein the rope is provided with a marking during the stranding thereof. The marking is changed during the stranding operation. Expediently, during stranding, the marking is provided successively with details characterizing the stranding progress. The details include production parameters, for example information relating to the length of the rope already formed, about raw materials used, the stranding speed and/or the current stranding time. The details are provided on a wire, a wire strand and/or a marking strand, wherein the details are printed on the wire, the wire strand or the marking strand or are embossed in the wire, the wire strand or the marking strand, and/or chips, preferably radio chips, are arranged in the rope.
A force transmission unit that has a rope, particularly a wire rope, and a device for introducing a force into the rope, that includes a sleeve enclosing the rope and connected to the rope under deformation. The force transmission unit has a connecting member which is arranged between the sleeve and the rope and formed from a material that has a lower strength than the materials from which the sleeve and the outer strands of the rope are formed and which preferably has a hollow cylindrical shape.

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.

A combined cable comprising a core cable of high-strength synthetic fibers, which take the form of a twisted bundle of monofilaments or a plurality of twisted bundles of monofilaments, and comprising an outer layer of steel wire strands, is characterized in that the bundle or bundles of monofilaments is or are stretched, with a reduction in diameter, and held in this state by a sheathing, in particular a braided sheathing. The extension under strain of the core cable under load is thereby reduced, so that the load distribution between the cross section of steel and the cross section of synthetic material of the cable improves.
The invention relates to a method for producing a strand or cable (20), in which fibres (2) and/or wires are twisted at a twisting point (3) to form the strand or cable (20). The fibres (2) and/or wires are coated with a liquefied matrix material (4) before 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 before and/or at the twisting point (3) and the formed strand or the formed cable (20) is 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 produced by the method.

CABLE, COMBINED CABLE MADE OF PLASTIC FIBERS AND STEEL WIRE STRANDS, AND COMBINED STRANDS MADE OF PLASTIC FIBERS AND STEEL WIRES
A cable of high-strength synthetic fibers is disclosed. The cable includes a core cable of high-strength synthetic fibres and an outer layer of steel wire strands. The synthetic fibres are present as a bundle of monofilaments or a plurality of twisted bundles of monofilaments, which is or are enclosed by a sheathing. The bundle or bundles of monofilaments is or are stretched with a reduction in diameter, and the sheathing sits on the bundle or the bundles so that the cross section of the bundle or the bundles assumed in the stretched state is fixed.
