Definitions

  • the invention relates to a spinning system for man-made fibers with a spinning shaft, which is formed as a tube and connects to the spinneret, the partial length of which is perforated and penetrates a blow box.
  • the invention is based on a prior art, as described for example in DE-OS 34 06 347.
  • the spinning shaft is perforated in the so-called distributor part of the blow box, but not in its inlet part.
  • the inlet part and the distributor box are connected by guide elements, the task of which is to even out the flow of the blowing medium.
  • a spinning system of the type described at the outset in that the perforated partial length of the spinning shaft adjacent to the spinneret is equipped with means by which the blowing air receives a speed component which is directed essentially radially to the spinning shaft axis and the means have the free cross section of the spinning shaft section at the location of their respective arrangement except for a central thread let it narrow.
  • the means mentioned are rings connected to the inner wall of the perforated spinning shaft part length, the free cross section of which has a diameter which essentially corresponds to the diameter of the local envelope of the thread sheet, but is not less than this.
  • These rings can be arranged flat and perpendicular to the spinning shaft axis or can also have a funnel shape pointing in the general direction of the thread.
  • the perforated edges of the rings are advantageously rounded to prevent damage to the threads of the thread sheet.
  • the ring hole delimitation can also be designed as a type of ring bead, which then, in order to avoid influencing the air flow, should not protrude beyond the ring surface pointing against the thread path, but should begin in it and thus lie flush with it.
  • An improvement in the blowing can already be achieved by arranging only one ring, but preferably several rings are provided; at least there should be two.
  • the diameter of the ring openings is advantageously only by a small amount, which prevents the tarnishing of the external threads of the thread sheet, larger than the diameter of the imaginary envelope of the thread sheet, and in such a way that the ring opening in its respective dimensions increases in relation to the size of the spinneret their summary of conically converging cords of thread is adapted at the location of the ring concerned.
  • the upper part of the spinning shaft 3 adjoining the spinneret 1 consists of the perforated section 6 and a short subsequent non-perforated section.
  • a further non-perforated section can be provided in the direct connection to the spinneret, which serves to reheat the threads emerging from the spinneret.
  • These parts of the spinning shaft 3 are surrounded by the blow box 4 with the air supply duct 5.
  • the blow box 4 is in turn subdivided into the lower inlet part 18 and the upper outlet part or distribution box 19 which is separated from the inlet part 18 by the distributor box base 17 consisting of a sieve-shaped distributor insert; the perforation of the section 6 of the spinning shaft 3 runs only in the distribution box 19.
  • the section that penetrates the inlet part 18 cannot; this must have no perforation.
  • the upper part of the spinning shaft can be lowered to carry out nozzle changes and the like.
  • the blow box 4 is connected via a support arm 8 to a guide carriage 9 running on a column 10.
  • the column 10 is anchored to the wall of the building via the cross member 11.
  • the upper part of the spinning shaft is held in its respective position together with the blow box 4 by a counterweight 13.
  • the means 20 indicated in FIG. 1 for narrowing the free spinning shaft cross section can be seen more clearly in FIG. 2.
  • nine rings 20 are provided in the drawing at a constant distance 21 from one another, this does not mean that such a number would always be required; in some cases, a single ring 20 may be are already sufficient, even if it has been found that generally at least two such rings 20 should be provided. The cheapest number depends on the local conditions such as the number of single threads, single thread titer, material, spinning speed, etc. If there are several rings, the mutual distance can be the same, but it can also increase, for example, in the direction of the thread.
  • the diameters 23 of the individual ring openings 22 are adapted to the shape of the thread sheet which becomes narrower after the point at which they are brought together; in any case, the diameter 23 of the individual ring opening 22 should be adapted as closely as possible to the local dimension of the thread sheet and at most only be so much larger that straight contact is prevented.
  • the air flow in the spinning shaft 3 is made more uniform by the arrangement of the rings.
  • the air radially enters the fiber bundle in all axially successive zones.
  • the heated air that has entered the interior of the fiber bundle is axially discharged in the center of the fiber bundle and cannot expand radially, thereby hampering the contact of the fiber bundle with fresh air in places.
