Abstract

L'invention concerne un dispositif de refroidissement d'un fil chauffé, le fil pouvant défiler au fond d'une longue rainure de refroidissement d'un corps de refroidissement. La rainure de refroidissement est reliée, par un orifice de dosage ménagé dans le fond de rainure, à un dispositif de dosage qui assure l'alimentation d'un liquide de refroidissement. Pour éviter les vicissitudes environnementales engendrées par les vapeurs et les liquides de refroidissement résiduels, l'invention prévoit que le corps de refroidissement soit encapsulé dans un boitier et que le boîtier présente une fente d'enfilage permettant l'introduction du fil, ladite fente d'enfilage s'étendant entre une entrée de fil et une sortie de fil ménagées dans le boîtier.
