Rope and method for producing a rope
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.
1. A method for producing a rope, comprising the steps of:
coating fiber bundles with a liquefied matrix material at least one of before and at a twisting point when forming fiber strands;
stranding the fiber bundles to form the fiber strands and embedding the fiber bundles in the liquefied matrix material during stranding;
solidifying the matrix material of the fiber strands after the stranding;
subsequently stranding the fiber strands directly with one another without a further coating of matrix material to form a fiber core of the rope; and
winding wires or wire strands around the fiber core, further including heating the fiber strands, during or after stranding thereof to form the fiber core, so that the matrix material softens at least individual of the fiber strands and binds to the matrix material of other respective fiber strands, and the fiber strands then solidify, forming an integral bond with one another.
2. The method according to claim 1 , wherein all of the fiber strands are softened.
3. The method according to claim 1 , including providing a sheath on the fiber core, the sheath being formed from the matrix material.
4. The method according to claim 3 , wherein the wires or the wire strands are embedded in the matrix material of the sheath.
5. The method according to claim 1 , wherein the fiber strands are parallel-stranded or layer-stranded to form the fiber core.
6. The method according to claim 1 , wherein during layer stranding, the fiber strands are stranded in different lay directions in order to influence torque generated on loading of the rope so that the fiber core or the entire rope is rotation-resistant or rotation-free.
7. The method according to claim 1 , including stranding the fiber strands in regular lay, in which fibers in the fiber strands and the fiber strands in the rope are wound in opposite directions, and in long lay, in which the fibers in the fiber strands and the fiber strands in the rope are wound in a common direction.
8. The method according to claim 1 , wherein before stranding onto the fiber core, the wires or the wire strands are preformed into a helical or approximately helical shape, which the wires or wire strands assume in the finished rope.
9. The method according to claim 8 , wherein only a single layer of the preformed wire strands is wound around the fiber core.
10. The method according to claim 8 , wherein at least two layers of the wire strands are wound around the fiber core.
11. A rope, comprising a fiber core having fiber strands, wherein the fiber strands are formed from fiber bundles embedded in a matrix material, stranded with one another in the matrix material; and stranded onto the fiber core are wires or wire strands, wherein the fiber strands are directly stranded with one another in the fiber core without additional coating of matrix material, wherein the matrix material bonds the fiber strands of the fiber core to form an integral bond between the respective fiber strands and the fiber strands are fused to one another.
12. The rope according to claim 11 , wherein a sheath is formed on the fiber core and the wires or wire strands are embedded in the sheath.
13. The rope according to claim 12 , wherein the sheath is composed of the matrix material.
14. The rope according to claim 11 , wherein the fiber strands of the fiber core are parallel-stranded or layer-stranded.
15. The rope according to claim 11 , wherein the fiber strands are layer stranded in different lay directions in order to influence torque generated on loading of the rope so that the fiber core or the entire rope is rotation-resistant or rotation-free.
16. The rope according to claim 11 , wherein the fiber strands are stranded in regular lay, in which fibers in the fiber strands and the fiber strands in the rope are wound in opposite directions, and in long lay, in which the fibers in the fiber strands and the fiber strands in the rope are wound in a common direction.
