Definitions

  • the cooling device 2 has a blowing agent 17 arranged outside the filament curtain formed by the filament sheet 3.
  • the blowing agent 17 is designed as an annular blowing nozzle 18 which essentially covers the entire circumference of the filament sheet 3 formed filament curtain. In this case, a distance is formed between the blowing nozzle 18 and the filament sheet 3, which is dimensioned such that an external cooling air flow generated by the blowing nozzle 18 is guided into the outer environment of the filament sheet 3.
  • the blowing nozzle 18 has a blowing opening 19 which is directed counter to the running direction of the filament sheet 3.
  • the blowing nozzle 18 is connected via a connecting line 20 to a compressed air source, not shown here.
  • a melted polymer is pump 6 fed to the ring spinneret 4 under high pressure via the melt distributor 5. Inside the ring spinneret 4, the polymer melt is on the underside trained variety of nozzle bores pressed, so that a variety of strand-like filaments arise.
  • the extruded filament sheet 3 forms an annular filament curtain that runs evenly from the toroidal nozzle 4 is deducted by a trigger mechanism, not shown here.
  • the blowing nozzle 18 is in the vicinity of the spinning device 1 is preferably arranged on the underside of the ring spinneret 4.
  • the Blower nozzle 18 is annular and substantially concentric with the Ring spinneret 4 held.
  • the blow opening 19 is on the underside of the blow nozzle 18 formed so that an outlet flow parallel in the running direction of the filament family 3 can be generated.
  • the blowing nozzle 18 is via the connecting line 20 connected to a coolant source, not shown here.
  • the distance between the blowing opening 19 and the blowing nozzle 18 and through the ring spinneret 4 extruded filament sheet 3 is dimensioned such that an external cooling air flow is performed in the immediate vicinity of the filament array 3.
  • FIGS. 1 to 3 Device for performing the method according to the invention are in their Structure and exemplary in its kind.
  • the invention extends not only to Embodiments shown here but include any familiar to those skilled in the art Spinning device, in which an annular filament sheet to one Filament curtain is generated.
  • the filament array 3 by means of several spinnerets held in an annular arrangement.
  • the exemplary embodiments shown for generating the outer and of the internal cooling air flow as an example. It is essential that the through the filament cluster 3 formed filament curtain from the inside and outside is cooled.
  • the blow candle 9 can have an outer one combine ring-shaped cross-flow blowing, whose Outlet flow is adjustable through a variety of fins.
