Definitions

  • the invention relates to a wire rope, in particular in Normalmachart, with a, in particular stranded on a core strand, inner strand layer, an outer strand layer and a plastic padding under the outer strand layer.
  • Such wire ropes are known in various designs.
  • the padding reduces the surface pressure on wire crossovers between the outer and inner strand layers.
  • a plastic interlayer is produced by extruding a thermoplastic material on a core rope and later the outer strand layer is stranded under impressions in the, reheated, plastic.
  • the DE 23 26 742 has the production of a plastic liner in a wire rope in parallel design to content, in which the inner and the outer strand layer must be stranded in one operation.
  • the plastic is previously extruded on the individual strands of the inner strand layer. When stranding, it is heated and squeezed out to a continuous liner.
  • the invention has for its object to provide a further type of upholstery, which requires the least possible effort.
  • this purpose is achieved in that in a wire rope of the type mentioned, the outer wires of the strands of the inner strand layer are coated with plastic.
  • Wires can easily be encased in plastic during manufacture, e.g. in the dipping process. Their warehousing in the wire rope shop has at only 15% of the weight fraction in the wire rope no significant cost-causing scope. The production of the strands and their stranding is not burdened with complications. There are no special operations added.
  • the plastic will usually be a not too soft thermoplastic. Duroplast but also come into consideration.
  • the drawing shows an embodiment of the invention. It shows a wire rope in a cross section.
  • 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 Normalmachart can be done in the same direction as the inner strand layer with different lay length or in the opposite direction of rotation.
  • the invention measure especially advantageous. Even with parallel stranding of the inner and outer strand layer, the measure is advantageous.
