Abstract

Un dispositif (10) de torsion de fils à brins multiples comprend un canal (20) de fil et des guides-fils (15, 16) agencés à une certaine distance de l'entrée et de la sortie du canal de fil de façon à presser le fil sur le canal de fil, lorsque l'amenée d'air comprimée est interrompue, de telle sorte que le fil s'étende dans le canal de fil parallèlement au sens longitudinal de ce dernier et que les parties droites du fil entre l'entrée et la sortie du canal du fil d'une part et les guides-fils d'autre part forment un angle aigu par rapport aux parties de l'axe longitudinal géométrique du canal de fil (20) situées à l'extérieur du canal de fil. En outre, l'angle de soufflage de l'ajutage souffleur est inférieur à 90°. La longueur du canal de fil (20) ne dépasse pas 40 mm dans le cas de fils unis, et 30 mm dans le cas de fils texturés. L'écart entre les guides-fils (15, 16) et le canal de fil (20) est égal à 30 mm au maximum. On obtient des vitesses d'avancement du fil particulièrement élevées et une excellente torsion du fil.
