Definitions

  • the invention relates to a ring spinning machine with compacting devices, each of which comprises a compacting strip having at least one perforation track, which runs over a suction shoe and faces a covering surface formed on an insert piece which is arranged on a support rail extending along the compacting devices.
  • Such compaction devices serve to suck up protruding fibers to the roving and thereby reduce the hairiness of the yarn produced. This also increases the tensile strength of the yarn and improves its processability into woven or knitted fabrics, see, for example, US 2001/0018823.
  • the coverage area assigned to the compression area shields the compression area from disturbing air turbulence, for example from a traveling cleaner. It has been shown, however, that build up at the edges of the covering surface having insert very easy accumulations of fibers that solve uncontrollably and can lead to thick spots in the yarn. These thick places reduce the quality of the yarn and can lead to thread breaks in its further processing.
  • the object of the invention was accordingly to make the insert having the covering surface so that the tendency to accumulate fibers is reduced. It solves this problem by the features mentioned in the characterizing part of the main claim.
  • the fact that the insert is designed as a plastic injection-molded part, it offers the possibility of burrs that can arise, for example, by machining, and often the one sharp edge having tool-separating line so that it faces away from the flow of material. This avoids the formation of fiber accumulations or if they should nevertheless have formed, they get into the material flow when they are detached.
  • the insert can "ride" on the support rail by abutting it with two legs on the two side surfaces thereof.
  • the insert comprises the support rail on all sides. This ensures the exact position of the insert and yet offers the possibility to put the front and rear webs viewed in the material direction in the longitudinal direction of the support rail against each other so that the dividing line of the injection mold is not in the range of material flow.
  • a curvature of the material flow opposite web of the insert in the direction against the flow of material has the advantageous effect that material deposits that might have formed on this surface, are pushed laterally and are not performed in the fiber flow.
  • the all-round gripping the support rail through the insert also provides the advantageous possibility, in the lower plate, so facing away from the flow of material, provide a clamping screw by means of which along the support rail, sliding insert can be fixed in functional position.
  • the compression device 1 which is the output roller pair 2 of a common drafting system, of which only this pair of output rollers is shown, is arranged downstream. With 3, the run of the fiber material is designated.
  • the compression device 1 is of a known type. It comprises a suction shoe 4, which is connected via a suction line 5 with a suction device, not shown here.
  • the suction shoe 4 has on its underside a suction opening 6, over which a compression straps 7 is guided. To the extent This compacting belt runs a perforation track of small suction holes, which is guided over the suction opening 6.
  • the compression straps 7 is moved over a pair of rollers 8, which is driven over all drafting systems of the ring spinning machine lower roller 9 and the upper roller 10 is spring loaded on a not shown upper roller support and loading arm pressed onto the lower roller.
  • Suction shoe 4 top roller 10 and compression straps 7 are guided in a cage 11, which is also supported on the support and loading arm and the guide bracket 12 and a squeegee strip 13 has for the compression strapping.
  • the suction opening 6 of the Sauschuhs 4 is opposite to a covering surface 14, whose contour is adapted to the curvature of Sauschuhs and which is integrally formed on an insert piece 15.
  • This insert engages around a support rail 16 which extends along all drafting of the ring spinning machine. Between the covering surface 14 and the underside of the compacting belt 7, a small distance is maintained, so that the belt does not touch the covering surface.
  • the insert 15 is formed as a one-piece injection molded part. It consists of an upper plate 17, from which the cover surface 14 rises and a lower plate 18, in which a threaded bore 19 is arranged and two, the two plates connecting webs 20 and 21.
  • the front, the material flow 3 opposite web 20th the insert 15 is in one piece, while the web 21 lying opposite it is divided into two parts.
  • the two parts of the web 21 are offset from the web 20 in the direction of the support rail 16 so that they do not overlap.
  • the threaded hole 19 can be cut into the full lower plate 18, but it is also possible to inject a smooth bore by means of a drawable core and cut into this a thread.
  • a clamping screw is screwed by means of which the support rail 16 displaceable insert 15 can be fixed in functionally correct position.
  • the front, the material flow opposing web 20 of the insert 15 advantageously has a cylindrical protrusion 24. Air and fiber accumulations that could be deposited on this web are stripped by the circumference of the circumference of this web orbital roller of the output roller pair 2 of the drafting system down / outside, so that they can not be drawn into the area of material flow 3.
  • One of the pair of output rollers 2 finished warped but wide leaking fiber structure is guided in the area between compression straps 7 and cover 14. There he is pulled by means of the directed through the suction holes of the compression strapping and the suction port 6 in the suction shoe 4 suction air flow laterally to the suction holes and thereby compressed and protruding fibers applied to him.
  • the so-compacted fiber structure is fed between the pair of rollers 8 through the downstream rotation zone in which it is given, for example by a ring / rotor device rotation and he is solidified into yarn.
