Definitions

  • the invention relates to a wire rope, in particular in normal design, with an inner strand layer, in particular stranded on a core strand, and a plastic padding under the outer strand layer.
  • the padding reduces the surface pressure at wire crossings between the outer and the inner layer of strands.
  • a plastic intermediate layer is produced by extruding a thermoplastic plastic on a core rope and later stranding the outer strand layer while being pressed into the, again heated, plastic.
  • DE 23 26 742 deals with the production of a plastic intermediate layer in a wire rope in parallel design, in which the inner and the outer strand layer have to be stranded in one operation. The plastic is previously extruded onto the individual strands of the inner strand layer. During stranding, it is heated and squeezed out to form a continuous intermediate layer.
  • DE 39 34 270 proposes to achieve the same result only with a plastic-coated core strand. The plastic should squeeze out of the core strand between the strands of the inner strand layer as far as the outer strand layer.
  • the invention has for its object to provide another type of padding that requires the least possible effort. According to the invention, this purpose is achieved in that the outer wires of the strands of the inner strands are sheathed with plastic in a Dra tseil of the type mentioned.
  • the plastic will usually be a not too soft thermoplastic. Thermosets are also possible.
  • the drawing shows an embodiment of the invention. It shows a wire rope in a cross section.
  • An outer strand layer 4 consisting of eight parallel lay strands 5 l + (6 + 6) + 12 is stranded on a core rope consisting of a parallel lay strand 1 1 + 8 + 8 as a core strand and a strand layer 2 composed of six parallel lay strands 3 1 + 8 + 8.
  • the outer wires 6 of the strands 3 are provided with a plastic sheath 7.
  • the plastic sheath 7 lies between the metal surfaces. It reduces the surface pressure.
  • the stranding of the outer strand layer in the normal manner can take place in the same direction of rotation as the inner strand layer with different lay length or in the opposite direction. In the latter case, the inventive measure would be particularly advantageous. The measure is also advantageous when the inner and outer strand layers are stranded in parallel.

Abstract

L'invention concerne un câble métallique, notamment de fabrication normale, dans lequel les fils extérieurs (6) des torons (3) de la couche de torons intérieure (2) sont enrobés de plastique (7). Grâce à cette introduction de plastique, limitée dans l'espace et en quantité, dans le câble métallique, une couche intermédiaire de plastique faisant rembourrage est placée à tous les croisements de fil entre la couche de torons extérieure et la couche de torons intérieure, ainsi qu'entre la couche de torons intérieure et le toron central ou une couche de torons plus à l'intérieur.
