Definitions

  • the invention relates to a texturing machine according to the preamble of claim 1.
  • the texturing machine is out of the DE 31 21 959 known.
  • heating devices are usually used today which have a heating temperature which is above the melting temperature of the thread material. These so-called high-temperature heaters make it possible to keep the texturing zone relatively short despite high yarn speeds of up to 1,200 m / min. In addition to the intensive heating of the thread, it is thus necessary that a coordinated on the heating of the thread intensive cooling is carried out by the cooling device.

This avoids shock-like cooling of the thread when the thread creeps onto the cooling tube. Since the cooling medium flowing from the outlet end to the outlet end is already heated by the continuous heat exchange between the outer surface and the cooling medium, the leading end of the cooling tube is cooled less by the cooling medium than the outflow end of the cooling tube. Another advantage is that the thread leaving the cooling device a having uniform temperature, since the outer surface of the cooling tube has a certain temperature determined by the supplied cooling medium in the outlet end. By flowing against the thread running direction cooling medium is achieved that the guided on the outer surface of the thread encounters a constantly cooler surface and thus is cooled more effectively, which is particularly advantageous for fixing the crimp in the thread.
