Abstract

L'invention concerne un dispositif de filage par fusion et de refroidissement d'une pluralité de filaments synthétiques. Ce dispositif comprend une unité de filage et une unité de refroidissement, l'unité de filage présentant au moins une filière servant à l'extrusion des filaments. Un cylindre perforé, présentant une enveloppe perméable aux gaz, est placé dans une cuve de refroidissement, sous la filière, pour refroidir les filaments venant d'être extrudés. Un déflecteur en U, entourant partiellement l'enveloppe et formant d'un côté une ouverture de soufflage, est associé au cylindre perforé. L'ouverture de soufflage communique avec un générateur de courant de refroidissement qui insuffle de l'air de refroidissement, s'écoulant transversalement au sens de déplacement des filaments, dans l'ouverture de soufflage. L'objectif de l'invention est de permettre d'obtenir une répartition, la plus homogène possible, de l'air de refroidissement à la périphérie du cylindre perforé. A cet effet, un répartiteur d'écoulement est placé dans l'ouverture de soufflage pour répartir l'air de refroidissement pénétrant dans l'ouverture de soufflage avant son arrivée sur le cylindre perforé.
