Definitions

  • the invention relates to a melt spinning device for a plurality of multifilament yarns according to the preamble of claim 1 and to a process for applying a plurality of multifilament yarns in a melt spinning device according to the preamble of claim 15.
  • a plurality of strand-like filaments are first extruded from a plurality of spinnerets.
  • each of the spinnerets has a plurality of nozzle bores, so that the filament strands extruded from a spinneret form a filament bundle.
  • each of the filament bundles is brought together separately to form a thread, so that a so-called first convergence point is formed in the spinning line.
  • This convergence point which defines the merger of the individual filament strands, is assigned to the spinnerets, so that a thread pitch is established which is substantially equal to a center distance of two adjacent spinnerets.
  • a spinning device is for example from the DE 199 29 817 A1 known.
  • the filament bundles are brought together in the convergence point by a preparation device into individual threads. Subsequently, the threads are guided with small thread spacing side by side in the downstream treatment device and treated.

Subsequently, the separation of the held together in a suction filament bundle to the threads in the convergence point and a merging of the threads to a treatment distance.
