It has surprisingly been found that the cooling flow flowing against the thread running direction does not become an essential one Increases the frictional resistance of the thread. On the contrary, the Counter current can be set so that there is no protective jacket in the form of a Can form air flow around the filament. The preferably from an air / liquid mixture existing cooling flow prevented the formation of a such protective jacket and led to intensive cooling of the filaments.
  • Another advantage of the invention is that the uniformity of the Filaments is given in that in the first cooling zone directly below the Pre-cooling takes place by means of an air stream. Through this Pre-cooling solidifies an edge layer of the filaments, which is sufficiently stable comprises in order in the second cooling zone with the air / liquid mixture To get in touch.
