Abstract

Le fil est acheminé à vitesse constante jusqu'à la bobineuse. La régulation de la vitesse de bobinage est assurée par le fait que le fil est guidé par l'intermédiaire d'un bras danseur. Outre la valeur mesurée qui représente la position du bras danseur, la vitesse à laquelle ledit bras danseur modifie sa position est déterminée. Les deux valeurs mesurées sont superposées et servent à déterminer une valeur d'ajustement pour le moteur de la broche.
