Definitions

  • the invention relates to a woven protective tube mentioned in the preamble of claim 1.
  • Such protective tubes are used in particular in round slings, in which the protective tube surrounds a load-absorbing core, which consists of one or more strands extending in the longitudinal direction.
  • Round slings with colored protective sleeves have been on the market for many years and are woven into the longitudinally extending black identification strips, the number of which indicates the maximum load capacity of the round sling, e.g. A label is provided for every 1000 kg.
  • the threads that are used to form these marking strips lie on the same plane as the other warp threads and are made of the same material as these, for example polyester yarn, so that the only difference between the threads used to form the marking strips and the other fabric threads is different Color is.
  • the invention is therefore based on the object of developing protective conduits of the type mentioned at the outset such that the recognition of the woven-in identification symbols is not significantly impaired by dirt or abrasion, even under harsh operating conditions, over long periods of time.
  • a protective tube designed according to the invention is extremely dirt and grease-repellent at the points where it bears the identification symbols, so that the symbols remain clearly visible even then. if the protective tube as such is heavily soiled or even smeared with oil or grease.
  • the identification symbols are strips extending in the longitudinal direction of the tube, so that the threads used for their formation form part of the warp threads and are arranged with them in a "plane".
  • these advantages can also be achieved in that the identification symbols lie lower than the outer surface of the remaining tubular fabric.
  • the threads used to form the identification symbols consist of metallized Monofilaments or from narrow strips obtained by cutting a metallized plastic film, for example a metallized polyester tape, of which several can advantageously be twisted together to form a thread.
  • Metallized is understood to mean both metal-coated and metal-coated materials.
  • the threads used to form the identification symbols can be obtained by spinning stainless steel chips.
  • a further advantage of using threads made of a metallized or metallic material is that these threads are electrically conductive, thereby avoiding different electrostatic charging of different areas of a protective tube according to the invention.
  • the threads consisting of a surface-protected material are woven together with initially non-dyed yarn, for example undyed polyester yarn, and the protective tubes produced in this way can only be subsequently dyed individually as a whole. Since the threads made of the surface-protected material do not take on any color, their good visibility is retained. The subsequent dyeing of individual pieces results in a much greater flexibility in adapting to customer requirements and it is not necessary to change the yarn packages on a weaving machine simply because a different color is to be used.
  • the shown round sling piece 1 comprises a core 2, which consists of a multiplicity of strands 3 running parallel to one another, each of which is formed by a multiplicity of twisted polyester threads.
  • This core 2 which in use forms the actual force-absorbing element of the round sling, is loosely surrounded by a protective jacket arrangement, which is formed by an inner protective jacket 5 and an outer protective jacket 6 to increase the cut resistance.
  • the inner protective sheath 5 consists entirely of a woven fabric of polyester yarns, while the outer protective sheath 6 also has longitudinally extending identification strips 8 which serve to indicate the maximum load capacity of the round sling in question (in the present case 3000 kg).
  • the identification strips 8, which are shown dark in the figure compared to the light-colored fabric of the outer protective jacket 6, are bright silvery shine in practice.
  • warp threads extending in the longitudinal direction of the tube are used, which are produced from a very thin, metal-coated polyester band material in that this band material is cut into narrow strips. To increase the tensile strength, these narrow strips can be twisted together to form thin yarn strands.
  • these warp threads do not protrude outward beyond the outer surface of the outer protective jacket 6, but preferably lie in the same or deeper layer or "plane" as the other warp threads.
  • the invention can also be used in round slings in which the protective sheath arrangement consists of only one protective sheath, into which the identification symbols according to the invention are woven.
