摘要： For the cooling of melt-extruded filaments of fibre-forming polymers spun from nozzle in molten form, said filaments are exposed to a medium prepared in foam form. The filaments emerging from the spinning nozzle are taken to the cooling area through said foam before passing on to a further process. The cooling medium, consisting of a liquid, is prepared by the addition of a gas.

摘要： Filament stress in a newly spun filament is reduced by avoiding or limiting air friction between the filament and the contiguous layer of air. This is done by producing an air stream that flows in the direction of travel of the thread at a speed which is the same or approximately the same as the surface speed of the filament. The air stream can be directed to the filament surface by means of a tube.
