Definitions

  • the invention relates to a drafting system for a spinning machine according to the Preamble of claim 1.
  • a so-called double apron drafting system is already known as prior art DE 4 323 472 C2), in which the fiber structure following the draft in one Fiber bundling zone is combined and twisted into a thread.
  • the fiber structure leaving the pair of output rollers of the drafting system becomes here over the length of the fiber bundling zone directed transversely to the transport direction Suction air flow exposed.
  • the prior art also includes a device for compacting a stretched one Fiber association DE 19 846 268 A1).
  • the drafting system is assigned a clamping roller on the output side, which is operated by one of the Drafting unit output rollers is driven.
  • the compression zone is as a suction device aligned in the form of a closed hollow profile, the outer contour of which Forms sliding surface and is wrapped in a conveyor belt.
  • Another state of the art is a double apron drafting system for spinning machines DE 4 13 90 67 C2), in which the fiber bundling zone is around the pair of rollers has running pair of straps that the sliver directly into the delivery roller pair passes.
  • the object of the present invention Invention to create a drafting system of the type mentioned, at which the compression in the area of the fiber bundling zone effectively and easily Way should be supported.
  • the second clamping point by one with the as an apron trained perforated transport means cooperating pinch roller
  • this is to the second clamping point tapered, designed as an upper strap around the second pinch roller and guided around a deflection element mounted at a height from the lower strap.
  • the height distance from the lower strap is advantageously adjustable, so that the gap in the area of the fiber bundling zone corresponding to the processing fibers, in particular staple fiber yarn, can be optimally adjusted.
  • the invention is described below using an exemplary embodiment shown in the drawing described in more detail.
  • the only drawing shows a schematic side view the fiber bundling zone of a drafting system for a spinning machine.
  • a drafting system for a spinning machine which is particularly useful for compressing staple fiber yarn on a ring spinning machine is provided, a pair of output rollers 1 with an upper roller 1.1 and a lower roller 1.2 has.
  • the output roller pair 1 is a fiber bundling zone 3 downstream, which one pneumatic compression device 4 with a perforated means of transport 6 wrapped suction shoe 8 contains.
  • the perforated means of transport 6 can for example, be designed as an apron.
  • This bottom strap can e.g. B. have a trace of holes as perforations.
  • the suction shoe 8 is connected to a vacuum source 10 connected and has a narrow, longitudinal suction slot 24th
  • the drawing also shows that the fiber bundling zone 3 is formed by two clamping points K 1 ; K 2 is limited.
  • the first nip point, namely K 1 is defined by the two rollers 1.1 and 1.2 of the pair of output rollers.
  • the nip K 2 is formed by the rollers 14 and 20 or by the straps 12 and 6 wrapping around them.
  • the upper roller 14 is pressed against the lower roller 20 and against the drive roller 22 running over the length of the drafting system by means of a loading device indicated only by an arrow 11, for example by a common, spring-loaded link.
  • the compaction unit is accordingly driven by frictional engagement from the drive roller 22.
  • the strap 12 tapering in a wedge shape to the second clamping point K 2 is assigned.
  • the strap running towards the second clamping point K 2 designed as an upper strap 12, is guided around the clamping roller 14 and around a deflection element 16 mounted at a height H from the lower strap 6.
  • the height distance H from the lower strap 6 can be adjusted.
  • the negative pressure is caused by the effect of Vacuum source 10 and the suction shoe 8 applied.
  • the bottom strap 6 with the top strap 12 has the advantage that the compression in the area of the fiber bundling zone 3 considerably supported by the wedge effect becomes.
  • the cleaning edge 18 has the function any fibers adhering to the strap 6 can be lifted off from this and a suction tube 23 feed.
