Abstract
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.
Claims22
A method for producing a strand, comprising the steps of:
- coating fibers and/or a monofilament bundle of fibers with a liquefied matrix material, that solidifies after stranding, before and/or at a stranding point;
- stranding the fibers and/or monofilament bundle of fibers at the stranding point to form a core strand, the fibers and/or the monofilament bundle of fibers embedding in the matrix material during stranding;
- applying a jacketing made of the matrix material on the core strand;
- and, after stranding the core strand, a) stranding a layer of steel wire on the jacketed core strand whereby the steel wire is embedded in the matrix material, and/or b) applying an additional jacketing on the jacketed core strand and embedding the additional jacketing on the matrix material.
A cable, comprising:
- a core cable containing monofilament bundles of fibers, wherein the fibers are natural fibers, mineral fibers, glass fibers, carbon fibers and/or synthetic fibers and the monofilament bundles are coated with and embedded in a matrix material so that each of the monofilament bundles is surrounded by the matrix material, wherein the matrix material forms a jacketing on the monofilament bundle of fibers;
- and a layer of strands cabled onto and embedded in the jacketing.
An apparatus for producing a strand or a cable, comprising:
- a device for supplying fibers and/or wires to a cabling point and for forming the fibers and/or the wires into a cable at the cabling point;
- a device for coating the fibers and/or the wires before and/or at the cabling point with a liquefied matrix material into which the fibers and/or the wires are embedded;
- and a device for applying a jacketing to the strand or cable, wherein the jacketing device is a braiding machine.
A method for producing a cable, comprising the steps of coating fibers and/or a monofilament bundle of fibers with a liquefied matrix material, that solidifies after cabling, before and/or at a cabling point;
- cabling the fibers and/or monofilament bundle of fibers at the cabling point to form a core cable, the fibers and/or the monofilament bundle of fibers embedding in the matrix material during cabling;
- applying a jacketing made of the matrix material on the core cable;
- and, after cabling the core strand, a) applying a layer of strands on the jacketed core cable whereby the strands are embedded in the matrix material, and/or b) applying an additional jacketing on the jacketed core cable and embedding the additional jacketing on the matrix material.
A strand, comprising:
- a core strand containing monofilament bundles of fibers, wherein the fibers are natural fibers, mineral fibers, glass fibers, carbon fibers and/or synthetic fibers and the monofilament bundles are coated with and embedded in a matrix material so that each of the monofilament bundles is surrounded by the matrix material, wherein the matrix material forms a jacketing on the monofilament bundle of fibers;
- and a layer of steel wires stranded onto and embedded in the jacketing.
A cable, comprising:
- a core cable containing fibers and/or monofilament bundles of fibers, wherein the fibers and/or the monofilament bundles are coated with and embedded in a matrix material and the matrix material forms a jacketing on the fibers and/or the monofilament bundle of fibers;
- a) a layer of strands cabled onto and embedded in the jacketing, and/or b) an additional jacketing provided on and embedded in the jacketing;
- and a jacketing, which is formed by a layer of braid and surrounds the core cable and holds the core cable together under tension.
