Definitions

  • the invention relates to a drafting system of a spinning machine, at least consisting of an apron draft zone according to the preamble of claim 1.
  • Such a drafting system is known, for example, from DE-B-11 15 160.
  • a tensioning device is described for top aprons of an apron drafting system which are guided in an apron cage with a rigid turning rail.
  • the bent reversing rail tensions the top strap by means of a resilient, supported tendon and is pressed against a fixed stop with an adjusting screw.
  • Such a conventional apron drafting system has the disadvantage that there is only a clamping surface between the two aprons. It is very difficult to apply a uniformly high pressure on the sliver to be drawn. In particular, the pressure on the pair of rollers of the apron drafting system is significantly greater than the pressure on the apron cage. This results in an uneven guidance of the fibers in the draft zone, which is particularly undesirable for spinning from an untwisted, parallelized fiber sliver.
  • the object of the invention is to improve a drafting arrangement of the type mentioned above in such a way that the fiber guidance between the two aprons becomes much more precise and the drafting arrangement is particularly suitable for the so-called band spinning.
  • FIG. 1 shows an apron warping zone 1 with input rollers 2 and 3 and output rollers 4 and 5.
  • a lower apron 6 is driven over the lower roller 2 and guided by a guide element 7 facing the pair of output rollers 4, 5 and a deflection roller 8.
  • An upper apron 9 is guided over the upper roller 3 and around an apron cage 10 (only indicated).
  • the cage 10 is pressed against the guide element 7 by means of a spring 11, the spring being supported against the machine frame 12.
  • the guide element 7 has a step 13 in the contact zone of the two straps 6 and 9 and an edge 14 facing the output roller pair 4, 5.
  • the end of the top apron cage 10 is now arranged above the edge 14 of the guide element 7, so that a second clamping surface is formed next to the clamping line between the rollers 2 and 3.
  • the distance between this clamping line and the clamping surface should be chosen so that it is less than or at most equal to the average staple fiber length to be processed.
  • the end 15 of the cage 10 and the edge 14 are both rounded so that excessive friction with the straps 6 and 9 is prevented.
  • the top strap 9 ' is shorter than the top strap 9 in FIG. 1.
  • the step 13 brings about a certain relaxation of the lower apron 6 in the region of the guide element 7.
  • this second clamping surface is fixed in the area of step 13.
  • Both variants ensure precise fiber guidance, the variant according to FIG. 1 ensuring that the fiber sliver is directed more towards the lower roller 5 and in the variant according to FIG. 2 towards the upper roller 4 and is given additional guidance through a kind of wrap around these rollers .
  • the end 15 of the upper apron cage 10 is arranged as close as possible to the lower roller 5 (FIG. 1) or the edge 14 as close as possible to the upper roller 4 (FIG. 2) of the pair of output rollers.
  • Both versions have proven their worth, especially for a ring spinning machine in which spinning is carried out directly from the untwisted sliver.
  • the above-mentioned drafting system is also extremely suitable for the known nozzle spinning.
