Definitions

  • the invention relates to a device for removing and treating a group of threads in a melt spinning process according to the preamble of claim 1.
  • a generic device for removing and treating a group of threads in a melt spinning process is known from DE 103 43 462 AI.
  • a plurality of fine filament strands is extruded from a polymer melt and combined after cooling to form a multifilament yarn in each case. It is customary here for a plurality of threads to be withdrawn together as a group of threads from a spinning device and to be guided to further treatment steps.
  • the cohesion of the filaments in the threads is ensured by a wetting, which is preferably applied to the filament strands immediately after cooling.
  • the thread closure produced with such preparation fluids is insufficient for a further processing process, so that the threads are vortexed before being wound up in a separate treatment step with a compressed air.
  • the treatment step for swirling the threads is preferably carried out between two driven godets.
  • a swirling device is arranged in the yarn path between two driven godets and has a separate treatment channel for each multifilament yarn.
  • Such a treatment of the thread with a compressed air leads in dependence on the respective working pressure of the swirling device, that partly volatile constituents of the thread are conveyed out of the treatment channels of the turbulizer by a blowing stream.
  • a swirling device is therefore known, for example from WO 2009/013107, which is arranged together with a preparation device in a housing.
  • the volatiles which accumulate in the housing are removed via a suction connection.
  • the known device requires the combination of the treatment steps for wetting the threads and for the twisting of the threads, which often take place at completely different locations of a melt spinning process.
  • DE 100 06 196 A1 also discloses a device in which a plurality of godets and a plurality of turbulizers are arranged together in a housing and in which the volatile constituents occurring due to turbulence are taken up and removed by suction become.

  • the invention is characterized in that a blast air emerging from the treatment channels is received and removed directly on the outlet side of the swirling device. Depending on the design of the suction nozzle, it can then be placed below, above or at the level of a threadline. Thus, the blowing currents occurring at the outlet side of the swirling device can be continuously absorbed and removed. Since in compressed air treatment of a multifilament yarn within a treatment channel only a portion of the blowing air passes to the outlet side, the development of the invention is particularly advantageous, in which an inlet side of the swirling device, a second suction nozzle is arranged, which has a suction opening at a free end and the connected to the suction device at an opposite end.

  • the deflection of the incoming blowing streams into the suction nozzle, the suction opening to the discharge opening are preferably carried out by a plurality of air baffles, which are held distributed with an inclination on the longitudinal side of the suction box. In this way, the blast streams entering the suction opening can be deflected towards the discharge opening.
  • the development of the invention is provided in which the discharge opening of the suction box opens into a suction opening which has a larger opening cross section than the discharge opening.

Abstract

L'invention concerne un dispositif servant à retirer et à traiter une nappe de fils dans un procédé de filage à chaud. Le dispositif comporte au moins deux galettes entraînées et un système de torsion disposé entre les galettes, le système de torsion contenant par fil un canal de traitement de fil. L'invention vise à éviter l'encrassement de la zone alentour du système de torsion par un flux de soufflage chargé en particules volatiles. A cet effet, une tubulure d'aspiration est disposée sur un côté de sorite du système de torsion, laquelle comporte, sur une extrémité libre, une ouverture d'aspiration et est reliée, par une extrémité opposée, à un système d'aspiration.
