Definitions

  • the invention relates to a rope formed of spirally wound strands completely surrounded by a plastic sheathing having projections extending into and filling gaps of dovetailed cross section defined between the outer strands of the rope, which are disposed at a certain distance from each other.
  • a rope of this structure is further improved by the fact that the outer strands are twisted in the opposite sense to the spiral winding of the strands forming the rope core. Underlying the gaps are supporting wires disposed in parallel lay to the outer strands, on which supporting wires the ends of the dovetail-like projections of the plastic sheathing abut.
  • the outer strands, the sheathing and the supporting wires together form a compression protection ring which, as a compact unit, largely screens and protects the interior of the rope from harmful radial pressures which, as is known, rapidly destroy the internal structure of the rope.
  • the rope core may consist of a strong core strand, on which the outer strands are immediately spirally wound, or else of a core and intermediate strands composed in the usual manner of round wires or, in accordance with a preferred form of the invention, inner strands with fiat wrapped wires are used, which provide especially favourable contact conditions.
  • the supporting wires may, as dictated by need or circumstance, consist of either metal or plastic. They pass over the rope core opposed to the strands forming this core, but in parallel lay to the outer strands, that is in the same direction and at the same pitch as these outer strands, in such a way that one supporting wire is disposed between each two outer strands.
  • thermoplastic plastic sheathing When the thermoplastic plastic sheathing is applied to the rope, it penetrates the gaps between the outer strands to such an extent that it permeates these in substantially dovetail form, finally abutting with the lower ends of the plastic material projections thus formed on the supporting wires.
  • FIG. 1 is a perspective view of the rope of the invention, while FIG. 2 is a section through the rope.
  • a core layer of strands 2 is twisted, whereby the elements 1 and 2 may be regarded as the actual rope core.
  • an inner layer of strands 3 is laid, whose peculiarity here consists in the fact that core wire 4 is sheathed by fiat wire: 5 rounded oil at both extremities of section.
  • this fiat-Wire sheathing is to enlarge the seating area of the inner strands and thus reduce the harmful effects arising from the radial, inward pressure from the outer strands when the rope is under stress.
  • FIG. 2 of the drawing clearly shows that, on the one hand, where the outer strands 7 are in contact with the inner strands 3, the bottommost round wire of the outer strand is in contact with flat wire 5 of the inner strand, while on the other hand each outer strand is held below by two supporting wires 6.
  • the entire rope is surrounded by a plastic, for example polyamide, sheathing 9 in such a way that projections 10 of the plastic material penetrate into the gaps 8 between the outer strands 7 sufiiciently deeply as to be secured in the form of a dovetail. Accordingly, the sheathing cannot possibly become detached from the outer strand layer while the rope is working.
  • the projections 10 extend so deeply into the gaps 8 as to reach the supporting wires 6.
  • FIG. 2 shows that in this way a firm protective ring is formed, composed of the supporting wires 6, the outer strands 7 and the plastic sheathing 9 and covering the rope core 1, 2 and the inner strands 3 like a shield. This protects the interior of the rope from centres of compression, such as occur when, for example, sudden rope stresses are necessary on an excavator or the like.
  • a rope comprising, in combination:
  • each supporting wire and the two adjacent outer strands defining circumferentially spaced and radially extending gaps of dovetailed cross section
  • a rope comprising, in combination:
  • each supporting wire and the two adjacent outer strands defining circumferentially spaced and radially extending gaps of dovetailed cross section
