A part of the cooling medium (30) is guided in the direction of the thread transport and another part is guided against the direction of the thread transport through parts of a duct (11). The duct (11) is provided with rectangular chambers (14), arranged mutually offset, causing repeated flow of the cooling medium (30) across the thread (1) under vigorous vortex formation.
