ABSTRACT:
A method for controlling a quench fluid velocity delivered to a quench zone in a polymer melt spinning process wherein the quench fluid velocity is measured by a velocity detector, compared to a desired quench air velocity and a damper valve mechanism is adjusted in a quench fluid duct so that the desired quench fluid velocity is obtained.
