  • the Sekundärblasluftstrahlen are thus at an angle ⁇ to the imaginary lines extending through the nozzle bores or vertical to the emerging from these nozzle bores filaments inflatable.
  • the direction of the imaginary straight line corresponds to the primary (undeflected) discharge direction of the filaments from the nozzle bores.
  • the Sekundärblas Kunststoff is orthogonal or substantially orthogonal to a running through a nozzle bore imaginary straight line or vertical inflatable.
  • Essentially orthogonal means that the angle ⁇ is 80 ° to 90 ° and preferably 85 ° to 90 °.
  • the secondary blowing air is blown at high speed to the filaments or to the filament curtain.
  • the vibrations of the filaments or of the threads are amplified both in their frequency and in their amplitude.
  • the invention is insofar the realization on the basis that additional draw points or additional points of the thread draw are generated in this way, so that a very effective and extensive stretching of the filaments is possible.
  • the at least one feed device for the secondary blowing air is set up with the proviso that secondary blowing air can be inflated with an elevated temperature compared with the room temperature (20 ° C.).
