Definitions
- the invention relates to a method for producing a rope, in which fiber bundles are coated in front of and / or at a point of attachment with a liquefied matrix material in order to form fiber strands and liquefied into the liquefied strand during stranding
- Matrix material are embedded, by means of the fiber strands, a fiber core of the rope is formed and wound around the fiber core wires or wire strands.
- the invention further relates to a producible by the method rope.
- this object is achieved in that the matrix material of the fiber strands is solidified after the stranding and the fiber strands are then directly stranded together to form the fiber core without further occupancy.
- the method can be produced in a simple manner, a fiber core, the fiber bundles, preferably completely, embedded in the matrix material and thus protected against breakage.
- the process is simplified considerably. Instead of the fiber strands in the formation of the fiber core with the
- the fiber bundles are embedded in the matrix material only in the production of fiber strands.
- the fiber core which may form the core of a strand of the rope or a core of the rope, the fiber strands may be wound after solidification of the matrix material using the conventional stranding methods and conventional equipment therefor.
- the method allows a production of the fiber core with a relatively large diameter and with a relatively complicated structure, which can not be formed at the stranding within the container or only with great effort.
- the inventive method Compared to the production of the fiber core of fiber strands, which have no embedded fiber bundles, the inventive method has the advantage that the handling of the fiber strands is much easier and that the produced fiber core due to the embedding of the fiber bundles improved mechanical
- the matrix material protects the fibers or the wires, connects them together and transmits occurring forces to them, in particular higher bending cycle numbers can be achieved.
- the matrix material is a thermoplastic
- Plastic is formed, which is heated to its liquefaction and cooled to its solidification.
- thermoplastic is used as the matrix material.
- polypropylene In addition to the preferred polypropylene used are polycarbonate, polyamide, polyethylene or PEEK in question.
- the fiber bundles are expediently sprayed with the matrix material or, as in a particularly preferred embodiment of the invention provided, immersed in the liquefied matrix material before and / or at the Verseilddling.
- the fiber bundles are, for example, as described in WO 2012/107042, moved through a, preferably heatable, container for receiving the liquefied matrix material, which surrounds the fiber bundles before and possibly at the stranding point.
- the container or the spraying device is connected to an extruder, by means of which the matrix material is liquefied and moved to the spraying device or into the container.
- Fiber strands at and / or after their stranding to the fiber core are heated such that the matrix material at least one of the fiber strands, preferably all of the strands, softens, bonds to the matrix material of each of the strands, and subsequently bonds the strands together, preferably to form a material bond Air or in a cooling liquid to be cooled.
- a homogeneous composite fiber core is formed, which has improved mechanical properties in comparison to loosely twisted fiber strands.
- the method makes it possible to produce such composite fiber cores with large numbers of cohesively interconnected fiber strands.
- the fiber strands are expediently stranded or stranded parallel to form the fiber core.
- the fiber strands can be used to influence a torque occurring when the rope is loaded in different directions
- Striking directions are stranded.
- a fiber core can be created, which is itself low-rotation or rotation-free.
- a low-torsional rope turns only slightly under load.
- the fiber strands and optionally the outer wires or outer strands are suitably beaten in such directions and lay lengths that the turning property of the rope is less than or equal to a rotation of the rope by 360 ° per rope length of 1000 d when lifting a load corresponding to 20% of Fmin,
- low-torsion rope to hit the fiber strands and possibly the outer wires in such directions and lay lengths that the turning property of the rope is less than or equal to a rotation of the rope of 36 ° per rope length of 1000 d when lifting a load which is 20% of Fmin , Conforms, more preferably, less than or equal to a rotation of the rope of 3.6 ° per rope length of 1000 d when lifting a load corresponding to 20% Fmin.
- the fiber core can be constructed in all imaginable cable arrangements.
- the Sea Sea, Filier, Warrington, Warrington-Seale, Seale-Seale, Seale-Filier, Seale-Warrington, Seale-Warrington-Seale wire assemblies are particularly suitable.
- a particular advantage has been found that it is possible with the inventive method to strand the fiber strands for the production of the fiber core in the same direction in which the fibers are twisted in the fiber strands and the fiber strands in the fiber core in the same direction.
- the inventor has recognized that such a stranding, which was previously not possible, because the stranded fibers wound up in stranding in the dc and accordingly the
- Fiber strands would have lost their structure during stranding, by means of the present method in which the fiber bundles through the matrix material in the
- Fiber strand structure can be held, perform. Stranded with dc Fiber strands generate a greater torque when the rope is loaded than stranded strand strands. This can be used advantageously for adjusting the torque occurring during the load. Thus, for each fiber strand a, depending on the respectively required torque generated by the respective fiber strands, it can be selected whether the fiber strands are in the same or in the same direction
- the fiber strands can be stranded out of the fiber bundles in the clockwise direction (Z-impact) or counterclockwise (S-impact) and, depending on requirements, the respective fiber strand layer in the Z-flute S-blow can be stranded.
- a U jacketing is provided on the fiber core.
- the corrugation is preferably formed of the matrix material, may also be formed by a different material that joins or adheres to the matrix material such that there is penetration between the fiber core and the umbilicus the compound formed or adhesion such large forces can be transmitted, that the connection or the liability under load of the rope holds.
- the material to similar material properties as the matrix material preferably it is formed from the same class of plastics. If the U mmantelung from the
- an amount of matrix material such that upon heating during the stranding of the fiber core on the fiber core, a quantity of matrix material can be arranged
- Layer of the matrix material forms.
- the sheath may also be applied in an additional process.
- the U mma ntelung is preferably provided in sufficient thickness to hetlitzen the wires or the Dra htlitzen at least in sections.
- the outer cladding can be provided in such a thickness that at least the wires or wire strands of inner layers of the rope are completely embedded in the U mma ntelung.
- the U mmantelung a can also be provided in such a thickness that even outer layers of wires or wires are completely within the U mmantelung, so that the U mma ntelung the rope terminates to the outside.
- the embedding also creates a positive connection between an outer layer of the strand or of the rope formed by the wires or the wire strands and the fiber core. While it might be imagined, the wires or the wire strands in one
- the wires or strands of wire are stranded on the fiber core directly after stranding of the fiber core on the fiber core in a period in which the Matrix material is still soft.
- Wire strands preformed before stranding on the fiber core preferably in or approximately in a Heilxform that they take in the finished rope.
- the cables made with the preformed wires or wire strands have lower or no residual stresses. They are cut firm, i. the wires or wire strands do not spread when the rope is cut.
- the preforming proves to be particularly advantageous when the rope has only a single layer of the wire strands, since the wire strands exercise in this structure a particularly large force on the fiber core and this can be significantly reduced by the preforming. It is understood, however, that the preforming of the wire strands can also be advantageous if the wire rope has two or more of the wire strand layers.

- another inventive cable 1 b is shown, the fiber strands are characterized in the drawing by hatching. It has a core cable 6b with 1 + 6 + 12 structure.
- the individual layers of the core cable 6b have been stranded from fiber strands 60 in opposite directions of impact.
- a strand layer of five strands 40 is arranged, which have a l +5 + (5 + 5) + 10 structure, wherein only the outer layer of the strands 40 of steel wires 42 and the inner l +5 + (5+ 5) structure is formed by fiber strands 41.
- the strands 40 are compacted as a whole, for example by hammering.
- an outer layer of outer strands 50 and 70 is wound.
- the outer strands 50 with fiber strands 51 and steel wires 52 have the same structure as the strands 40 and have also been compacted, but have a smaller diameter.
- the outer strands 70 have a l +6 + (6 + 6) + 12 construction.
- a strand outer layer is formed by steel wires 72 and the inner side of the strand, i. the l + 6+ (6 + 6) structure is formed by fiber strands 71.
- the outer strands 70 have been compressed.
- All of the fiber strands 60, 41, 51, 71 required for the formation of the cable 1b were made by the method described above and heated while being stranded to form a one-piece fiber core.
- such an amount of thermoplastic material for example PEEK, has been provided that when heated after being bonded to the respective fiber core has formed a sheath of the thermoplastic material, in which the outer steel wires 42,52,72 have been embedded.
- the core strand 6 b and the strands 40,50,70 have been embedded in a matrix material 80 made of thermoplastic material.
- the matrix material 80 may be made of the same plastic in which the fiber bundles of the fiber strands 60,41, 51, 71 have been embedded (eg PEEK) or by another plastic, such as polycarbonate, which adheres to the thermoplastic material, possibly chemically with it connects, be formed.
- the fiber strands 60 b, the strands 40 and the outer strands 70 may also be struck in such a way that the cable 1 b is low-torsionally and thereby, for example, a turning characteristic of a twist of the rope smaller 36 ° / 1000 d rope length when lifting a load corresponding to 20% of Fmh has.
- a cable 1c shown in Fig. 7 has a core rope 6c of l +6 + (6 + 6) + 12 construction.
- An outer layer of the core rope 6c is formed by steel wires 62c.
- the inner l + 6 + 6 (6 + 6) structure of the core cord 6c is constituted by a fiber core whose fiber strands 60c made by the above-described method are stranded in parallel and bonded together as described above in the stranding under heating.
- Leads 40c wound around the core cord 6c have a fiber core formed of a single strand of fiber 41c and steel wire wires 42c stranded thereon (1 + 6 structure).
- An outer layer of the rope 1 c is formed by steel wire strands 70 c.
- the matrix material 80c preferably consists of the same
- thermoplastic e.g., polyamide
- the rope c is in total, e.g. by hammering, compacted.
- the steel wires 62 c, fiber strands 60 c, the strands 40 c and the Stahldrahtliitzen 70 c may be beaten so that the cable 1 b is low in rotation and thereby, for. a turning characteristic of a twist of the rope less than 18 ° / 1000 d rope length when lifting a load corresponding to 20% of Fmh. It is understood that the wire having strands of ropes 1 a, 1 b, 1 c, 1 d, 1 e of FIGS. 5 to 9 also, as explained above for the wire rope 1, may be preformed.
