Abstract

L'invention concerne un procédé et un dispositif pour le tourbillonnement d'un fil multifilament, dans lequel un morceau de fil libre est formé par deux zones d'appui adjacentes dans une chambre à air au niveau du fil courant, et dans lequel un courant d'air comprimé dans la chambre à air agit sur le morceau de fil libre. Afin d'obtenir un tourbillonnement uniforme et à frottement réduit du fil, l'invention prévoit que les zones d'appui soient déplacées ensemble dans le sens d'avancée du fil pour le guidage du morceau de fil. Pour cela, les moyens d'appui pour le guidage du fil sont réalisés de façon amovible afin de coopérer dans une chambre à air avec un dispositif à buses pour la génération d'un courant d'air comprimé.
