Abstract
A process for producing spin-oriented continuous filaments at a draw-off speed of more than 2400 m/min, whereby the filaments extruded through the spinnerets of the spinning heads are cooled in cooling shafts by the ambient air entrained as a result of the suction action of the filaments and the filaments leaving the cooling shafts enter a chamber that is separate from the intake environment where the air pressure is regulated at a lower pressure in comparison with the air pressure in the intake environment.
