Abstract

L'invention concerne l'industrie textile. Le dispositif faisant l'objet de l'invention est du type comprenant une chambre de filage cylindrique 1 montée fixe communiquant avec un système d'aspiration d'air et munie d'une tubulure 5 pour l'amenée tangentielle de fibres 6 dans cette chambre, et d'une tête 7 montée dans la partie supérieure de la chambre de filage et est caractérisé en ce que ladite tête est disposée de telle façon dans la chambre de filage que la distance << 1 >> entre l'orifice d'entrée du canal de sortie du fil fini et le point de l'ouverture de sortie de la tubulure qui est le plus rapproché de ladite tête soit comprise entre 2/10 et 8/10 de la valeur du diamètre intérieur de la chambre de filage. L'invention permet notamment de réduire les dépenses d'énergie grâce à l'augmentation du moment de torsion pour un même débit d'air.
