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 patent claims 1 and 2.
  • Such a drafting system is known from DE 11 44 160.
  • the sliver runs out of the nip zone between the lower apron and the upper apron over a comparatively large distance, unguided, into the nip of the pair of output rollers, with individual fibers being able to detach from the stretched tape.
  • the invention is based on the object of improving 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.
  • 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 ends 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 in the area the level 13 set. Precise fiber guidance is ensured, the fiber sliver being directed more towards the lower roller 5 and being given additional guidance by a kind of looping 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) of the pair of output rollers.
  • the device has proven itself, in particular for a ring spinning machine in which untwisted sliver is spun.
  • the above-mentioned drafting system is also suitable for the known nozzle spinning.
