Description

Stranded or rope tape with a plastic coating

The invention relates to a stranded and / or rope band with a plastic sheath.

There are stranded or rope straps or combinations of both known for a wide variety of purposes, which have a plastic casing. This is used in usually the protection of the individual strands or wires, but does not absorb any tensile or compressive forces.

For special areas of application, stranded or rope straps are required that are twist-proof, for example Example on cranes or trolleys when the goods to be transported hanging on the ropes do not turn

are allowed to execute an axis. Furthermore, Litzenoder are often used Cable straps are required that have a certain low elongation under tensile load and a certain inherent stiffness under pressure load have, so that, for example, with such stranded or rope straps not only tensile forces, but also - to a lesser extent, compressive forces can be exercised.

The invention is based on the object of creating a stranded and / or rope belt of the type mentioned at the outset, which is attached to Transmission of large forces is secure against twisting and which is also suitable for a certain tensile force and / or compressive force transferred to.

The solution to this problem is that, according to the invention, the individual strands or ropes are embedded separately from one another in the plastic casing, which is an extruded, solid strand, _{see FIG}

In a preferred embodiment of the invention, the individual Strands or ropes in one plane, the plastic covering being a flat band.

The stranded and / or rope tape according to the invention has the salient advantage over the known stranded or rope tapes, that it is absolutely secure against twisting. With a stranded and / or rope tape according to the invention, especially if the individual If strands or ropes lie in one plane, loads can be absolutely free of distortion be lifted, which eliminates the hazards emanating from rotating, elongated parts. Furthermore lets The stranded and / or rope tape according to the invention can be easily reeled in, whereby it is easy to guide in terms of its position.

Furthermore, the stranded and / or rope tape according to the invention has an inherent rigidity, whereby forces can also be transmitted to a certain extent with the same. The plastic

hüllung gives a much greater inherent rigidity of the stranded and / or rope belt when it together knitted strands or cords with a mere plastic jacket wrapping have _e Thus can be goods not only draw on flat plains or rails, but also press in lesser extent.

Furthermore, in an advantageous embodiment of the invention, the plastic sheath between the individual strands or ropes have a perforation. Or the plastic sheath can have teeth between the individual strands or ropes. As a result, a greater force can be transmitted in the longitudinal direction in a particularly advantageous manner. The perforation or the teeth can also be used as a positive guide.

Examples of the invention are shown in the drawing and then described.

The strands lie in one plane, Fig. 2 a and b shows a stranded strip in which the individual strands

do not lie in one plane and the plastic =

strand has a circular cross-section and Fig. 3 a.u. b another stranded tape in which all strands

lie in one plane and the plastic strand a

flat band is.

The stranded and / or rope tape 1 according to FIG. 1 consists of three strand bundles 2, 5 and 3, each of which consists of individual wires 6 exist. These wires 6 are, as in Fig. 1 a schematize !! shown, not twisted together. The individual strand bundles 2, 5 and are, now at a distance from each other in an art st of is rank 1 a

embedded, which in this example is designed as a flat band and keeps the individual strand bundles at a distance. Between the bundles of strands there is a continuous perforation k , which can serve as a forced guidance or can engage in the teeth of a gear for forced guidance or to increase the force transmission in the longitudinal direction,
