  • Roving is produced with the aid of roving machines, usually with the aid of stretch-pretreated (eg doubled) slivers, and serves as a template for the subsequent spinning process in which the individual fibers of the roving are spun into a fiber yarn, for example by means of a ring spinning machine ,
  • stretch-pretreated eg doubled
  • slivers serves as a template for the subsequent spinning process in which the individual fibers of the roving are spun into a fiber yarn, for example by means of a ring spinning machine
  • Said strength is important to prevent ripping of the roving during winding on a spool or during the supply to the downstream spinning machine.
  • the protective rotation granted may only be so strong that a cohesion of the individual fibers is ensured during the individual winding and unwinding operations as well as corresponding transport processes between the respective machine types.
  • the protective rotation it must be ensured that the roving can be further processed in a spinning machine - the roving must therefore continue to be delayable.
  • flyers In order to produce a corresponding roving, so-called flyers are primarily used, but their delivery speed is limited due to centrifugal forces occurring. Therefore, there were already many suggestions to bypass the flyer or to replace it with an alternative machine type (see for example EP 0 375 242 A2 . DE 32 37 989 C2 ).
  • the vortex air flow at this initial stage usually has a different characteristic than during regular spinning operation in which the vortex chamber is already passed by a continuous fiber strand (the fiber strand is made up of the fiber structure in the region of the inlet opening of the spinneret and within the vortex chamber the roving produced by the fiber structure and the vortex chamber leaving a vortex channel together).
  • the object of the present invention is to propose a spinneret and an air-spinning machine equipped therewith for the production of roving in which the individual flow sections for the spinning and piecing air are advantageously positioned and aligned.
  • JP S61 119725 discloses a pneumatically operated nozzle.
  • DE102007006674 discloses an air-spinning device for producing a thread by means of a circulating air flow.
  • DE 102 51 727 A1 DE10351727 discloses a method and apparatus for making a flyer.

  • the solution according to the invention has the advantage that the Anspinn Kunststoff inlet openings (over which the Anspinn Kunststoff enters the Anspinn Kunststoffkanal) seen in the transport direction after the spinning air inlet openings (on the the spinning air enters the spin air duct) can be placed.
  • the Anspinn Kunststoff outlet openings (over which the Anspinn Kunststoff enters the vortex chamber) can thus be placed in the transport direction approximately at the height of the spinning air outlet openings, yet both air channels (spinning air duct and Anspinn Kunststoffkanal) can be supplied by different sources of compressed air.
  • the Anspinnluftkanal comprises a first channel section, which extends from the Anspinn Kunststoff inlet opening within the Wirbelhuntwandung at least partially opposite to the transport direction, wherein the Anspinn Kunststoffkanal beyond a second channel section includes, extending from the first channel portion in the direction of Anspinn Kunststoff-outlet opening.
  • the Anspinn Kunststoff entry in this case is not continuous straight. Rather, the course of Anspinn Kunststoffkanals (which generally extends between the Anspinnluft inlet opening placed in the region of the outside and the Anspinn Kunststoff-outlet opening into the swirl chamber) within the Wirbelbibdung changes at least once.
  • the first channel section starting from the piecing air inlet opening, runs counter to the transport direction and parallel to a central axis of the spinneret. Within the vortex chamber wall, he finally goes over, for example via a kink, in the second channel section, which in turn extends in the direction of the vortex chamber.
  • the first channel section (in a side view of the spinneret) encloses an angle with a central axis of the spinneret whose magnitude is 0 ° to 30 °, preferably 0 ° to 15 °, particularly preferably 0 ° to 10 °, is. While an angle of 0 ° means that the first channel section is parallel to the central axis of the spinneret, an angle greater than 0 ° results in the first channel section being inclined with respect to the central axis.
  • first channel section and / or the second channel section have a rectilinear central axis.
  • the respective channel section can be made through a corresponding bore which is introduced into the vortex chamber wall.
  • impairments of the respective air currents are avoided.
  • the diameters of the respective channel sections are preferably the same size or deviate from each other by only a maximum of 20%.
  • first channel section and / or the second channel section is formed by a bore introduced from the outside of the spinneret into the spinneret.
  • a bore can be easily and especially, with respect to its orientation, very precisely introduced.
  • first channel section and the second channel section through a from the outside of the spinneret in the spinneret introduced bore is formed, wherein the respective holes intersect within the Wirbelfflewandung.

  • the second channel section extends from the piecing air outlet opening into the first channel section.
  • the second channel section branches off at an angle ⁇ from the first channel section, wherein the amount of said angle is 40 ° to 80 °, preferably 45 ° to 75 °, particularly preferably 50 ° to 70 °.
  • Such an angle causes an air flow, which does not have to be redirected again before entering the vortex chamber and thus promises a successful piecing without further intervention.
  • the spinning-air outlet opening and the piecing-air outlet opening are arranged in a common plane extending perpendicular to the transport direction or less than 3 mm, preferably less than 2 mm, particularly preferably less than 1 mm, viewed from one another in the transport direction are spaced. Nevertheless, the spin air duct and Anspinn Kunststoffkanal of separate Compressed air supplies are supplied, since the spinning air inlet opening and Anspinn Kunststoffeintrittsö réelle seen in the transport direction are spaced from each other.
