This allows a winding with substantially constant thread tension and thus a good bobbin build achieve. Because the force of the dancer arm acting on the dancer arm role is absorbed by the number of wraps, the force to be absorbed in the thread.

Abstract

L'invention concerne un procédé et un dispositif pour enrouler sur une bobine (4) un fil (2) arrivant à une vitesse constante, au moyen d'une broche de bobinage (3) entraînée par un moteur (18). Le fil est amené à un dispositif va-et-vient (8) qui pose le fil, en un mouvement alterné, le long de la surface de la bobine perpendiculairement à son sens de défilement. Avant son introduction dans le dispositif va-et-vient, le fil est guidé avec un fléchissement par le rouleau (10) d'un bras danseur (9), ce rouleau (10) étant placé entre deux guide-fils (14, 15) fixes. La vitesse de la broche de bobinage est réglée en fonction de la position du bras danseur de telle manière que le fil présente un fléchissement constant entre les guide-fils (14, 15) fixes. Selon l'invention, le fil est entouré plusieurs fois partiellement sur le rouleau (10) du bras danseur de telle manière que l'amplitude du mouvement du rouleau puisse être réduite proportionnellement au nombre de tours en question.
