Definitions
- the invention relates to a method for producing a strand or a rope, in which fibers and / or wires are stranded at a stranding point to the strand or the rope.
- the invention further relates to a device for carrying out the method and a producible by the method rope.
- Such methods known by use, with which natural fiber, plastic fiber and wire strands or ropes are produced, are normally performed with a stranding machine.
- a stranding machine On a rotor of the stranding machine coils are arranged, are wound on the fiber strands or the wires to be stranded. As the rotor rotates, the fiber strands or wires are routed to the stranding point where they are twisted into the strand or rope and the formed strand or rope is rolled up onto a cable drum.
- strands and ropes are also made, the high-strength plastic fibers from e.g. Aramid have.
- Such strands and ropes have a high strength in relation to their weight and their volume.
- the plastic fiber ropes are used in climbing sports for securing mountaineers.
- the advantage also has a positive effect on the use of plastic fibers in wire ropes of great length for hanging use, for example in mining ropes or in deep-sea ropes.
- the weight of the wire ropes itself already claimed a large part of their carrying capacity; the payload is limited accordingly.
- the problem with the plastic fibers is that although they have a very high strength in their longitudinal direction, but only a very small and therefore there is a considerable risk of breakage under appropriate load.
- the plastic fiber ropes used to secure climbers usually have a core-sheath structure in which the core consists of stranded fiber strands.
- the stranded fiber strands are protected from damage by a sheath that is braided around them and holds them together.
- the invention has for its object to provide a method of the type mentioned, with which can be produced strands or ropes, which have over the known strands or ropes improved mechanical properties.
- the object is achieved in that the fibers and / or the wires are coated with a liquefied matrix material before and / or at the stranding point and embedded in the matrix material during stranding.
- a strand or a rope can be produced in which the fibers or, if the fibers are present as monofilament bundles, the monofilament bundles or the wires in the strand or in the rope are surrounded by the matrix material, and Spaces between the wound to the strand or the rope fibers, monofilament bundles or wires are filled with the matrix material.
- the strands or ropes have particularly advantageous properties if the fibers, the monofilament bundles or the wires are completely surrounded by the matrix material at least in those sections of the strand or rope in which they are not located on the strand or rope surface. It is thus possible to produce a particularly homogeneous strand or a particularly homogeneous rope.
- the strand or the rope can be coated simultaneously with the matrix material. The masticator protects the fibers or the wires, connects them together and transmits forces to them. A composite rope with improved mechanical properties is created.
- the choice of matrix material can advantageously influence the mechanical properties of the strand or of the rope.
- the strength is greater in choosing a high strength matrix material than in choosing a low strength matrix material.
- each of the monofilament bundles is covered with the matrix material and embedded in the matrix material during stranding, wherein each monofilament bundle remains surrounded by the matrix material.
- Dependent u.a. from the viscosity of the matrix material and from the wetting properties of the matrix material on the fiber material, individual monofilaments of the monofilament bundles lying outside the monofilament bundle may also be surrounded by the matrix material at least in the monofilament bundle.
- the monofilament bundles and possibly the individual fibers are separated from one another by the matrix material, so that a mutual load in the direction perpendicular to their longitudinal direction is reduced. The risk of breakage is considerably reduced.
- the strands or ropes are more resistant and have a longer life compared to the known strands or ropes.
- thermoplastic is used as the matrix material.
- polypropylene are polycarbonate, polyamide, polyethylene or PEEK in question.
- the fibers embedded in the matrix material may form a core of a combined strand having an outer layer of steel wire.
- the embedded fibers may be a core rope of the rope and the rope may have an outer layer of strands, preferably of steel wire strands or of said combined strand with the core of the fibers and the outer layer of the steel wire.
- the strand or rope is completely embedded in the matrix material.
- the matrix material then forms a sheath and thus a protection to the outside.
- it may serve as the strand or the core rope of surrounding strands.
- the rope can also be produced from wires and / or fibers already stranded into strands.
- the strands to be stranded are embedded in the matrix material, wherein the matrix material can fill in any cavities present in the strands.
- strands made by the method described can be used.
- Ropes with a core-shell structure can be produced more easily by means of the method. While it was previously necessary to embedding the core rope to carry out the process in two process steps, namely first the sheathing of the core rope and the subsequent stranding of the strands on it, this can be carried out by means of the method according to the invention in a single process step.
- a means for occupying the fibers or wires to a stranding device is provided, with which both the core rope can be produced as well as the strands can wind on the core rope (tandem stranding machine).
- the core rope is covered with at least the stranding of the strands with the matrix material.
- the fibers, wires and / or strands used to make the core rope are already embedded in the matrix material.
- a, preferably heatable container for receiving the liquefied matrix material is provided for this purpose, which surrounds the fibers and / or the wires or the strands before and possibly at the stranding point.
- a spraying device for spraying the liquefied matrix material may be provided.
- the device for carrying out the method, at least in the area in which the matrix material is sprayed, is provided with a protective wall which closes the device to the outside in order to prevent sprayed matrix material from entering the environment.
- a space formed by the protective wall can be provided with a trigger and a corresponding filter.
- 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 to the container.
- a device for measuring the temperature of the container is provided to ensure that the container is heated so that the matrix material remains liquid in the container.
- the temperature can also change the viscosity of the matrix material and influence the wetting on the fibers or wires.
- the container has a rotatable side wall which is provided with openings through which the fibers, the wires and / or the strands are led to the stranding point.
- the rotatable side wall is rotatable at the same rotational speed as a rotor through which the fibers, the wires and / or the strands are led to the stranding point.
- the openings are provided with seals which prevent the matrix material from coming out of the container.
- a further opening is provided, through which the formed strand or the rope formed is to be guided.
- the further opening has a diameter which corresponds to the outer diameter of the strand to be formed or of the rope to be formed.
- the rotatable side wall and the rotor are interconnected.
- the rotor guides the sidewall during rotation.
- the container is closed except for the said openings.
- the matrix material may be in the container under elevated pressure, so that it can better wet the fibers or better penetrate into any existing cavities.
- the strand or rope is used to solidify the matrix material, preferably in air or in a cooling liquid, e.g. Water, cooled.
- a cooling liquid e.g. Water
- a calibration ring is arranged in the container, through the opening of which the strand to be formed or the rope to be formed is pulled during stranding.
- the fibers and / or wires of the strand or rope can already be brought into the intended form within the container.
- the container is expediently provided at the end, on which the formed strand or the cable formed is drawn, with a pipe section having a larger inner diameter than the opening of the Kalibrierrings and in which the matrix material cools and solidifies.
- Tube section can be used with a with a cooling device, e.g. a water cooling, be provided.
- a cooling device e.g. a water cooling
- the fibers will be stretched during stranding, embedding in the matrix material and cooling of the matrix material until solidified, such that the fibers are held by the matrix material in a position which they occupy in the stretched state.
- the fibers will be stretched so far that they are brought into a position that they take on load absorption, preferably such that so far that they are stretched plastically when loaded by the strand or the rope directly in accordance with Hooke's Law.
- the load bearing can be improved by this measure.
- the actual load absorption of non-stretched strands or ropes made of fibers only sets in with a delay because the fibers must first "settle" with each load, ie have to find a final spatial allocation to form a stable cross section If the fibers are already stretched during the stranding and held in tension until the matrix material has solidified, then they are held in the stretched state by the matrix material, and the fibers are frozen in the stretched state made of a core of fibers and strands of steel, the expansion behavior of the core rope to the expansion behavior of the wire strands are adjusted and the core rope thus take over a significant proportion of a load.
- the sheath which is preferably formed by a braid, applied under tension, it may serve to hold the fibers in the above-described biased state, or at least to assist.
- sheathing is also embedded in the matrix material, a particularly good bond between the fibers and the sheathing can be achieved.
- a particularly strong bond can be achieved if the braiding is formed of fibers of different thicknesses and / or if it is formed with stitches, the matrix material penetrates the meshes.
