Definitions

  • the invention concerns a method for producing a wire cable with a core cable or core strand, in which, after the outer strand layer has been stranded, the wire cable is hammered to smooth its surface and/or to increase its space factor.
  • Wire cables of this type are well known for special applications in which a smooth surface of the wire cable is of prime importance, e.g., because they are dragged over the ground.
  • An example of such applications is the lumber industry.
  • the objective of the invention is to prevent wire damage caused by hammering to the greatest possible extent.
  • this objective is achieved by applying an intermediate layer of a plastic material to the core cable or core strand before the outer layer of strands is stranded and by pressing the outer layer of strands into the plastic during the stranding process.
  • the support of the outer strands on the elastic plastic does not impair the hammering and the desired deformations.
  • a hammer works in which hammers adapted to the curvature of the surface of the cable strike simultaneously from different sides and essentially completely surround the surface of the cable at the instant of their simultaneous striking of the surface of the cable on an axial length of at least twice the cable diameter, the plastic apparently does not have enough time or space to escape from under the blow.
  • the cavities between the outer layer of strands and the core cable or core strand are preferably filled with the plastic as far as the wedge-shaped spaces between the wires bounding these cavities.
  • Deformation of the outer strands occurs, more or less excluding those cross-sectional regions of the wire on the underside that are surrounded by the plastic and receive the counterpressure of the plastic everywhere perpendicular to their surface; they are thus not exposed to any deforming forces here. Directed forces, which deform the wires, occur on the upper side of these wires, which is not surrounded by plastic. Under these conditions, very strong deformation of the outer strands is possible. If the outer strands constitute a large portion of the cable diameter, reductions of the diameter of the wire cable of more than 10% can be achieved. A 5% reduction of the diameter can probably be achieved in most cases.
  • the plastic intermediate layer does not really act as direct cushioning between these wires, but rather the conditions are comparable to a confined liquid, in which the pressure is exerted towards all sides, so that no significantly increased forces at all arise between the intersecting wires.
  • the aforementioned compression of an outer strand layer on an elastic substrate made of plastic in accordance with the invention can also be realized in a wire cable with a core that consists exclusively of a plastic strand: here too, the wire cable can be hammered after the stranding of the strand layer, and thus the strand layer can be compressed and smoothed.
  • the wire cable receives a higher space factor and becomes resistant to surface wear, especially when running over rollers.
  • strands with a readily deformable core, e.g., a core of soft iron or plastic.
  • the hammers should have an axial extent of at least twice the cable diameter and preferably should have an expanded, tapering inlet.
  • a wire cable of the invention could additionally be subjected to a surface treatment or coated or provided with a sheath.
  • the wire cable can also serve as the core cable for the production of a wire cable, which then has, for example, an additional counterwound strand layer on the smooth surface.
  • the cross-sectional drawing shows an embodiment of a wire cable produced in accordance with the invention.
  • a core cable 1 which consists of a central core strand 2 (1+6) and six strands 3 (1+6), is surrounded by a thermoplastic 4 .
  • an outer strand layer 5 that consists of six strands 6 (1+6) is pressed into the plastic 4 , which has been softened by heating.
  • the wire cable produced in this way was hammered in the manner described above.
  • the core cable 1 was also somewhat deformed and compressed, but this occurred to only a slight extent in this case and is not shown in the drawing.
