ABSTRACT:
A liquid jet, which is not decomposed to droplets, is guided onto a hot yarn wad in a cooling section with rod guide means, and this leads to rapid, very uniform cooling. Smooth thread travel is produced during take-off at thread speeds of 2000 m/min and more. One deflection of the thread is usually sufficient for drying purposes since the liquid is thereby centrifuged off.
