Abstract

L'invention concerne une machine de bobinage et un procédé permettant de bobiner un fil arrivant en continu pour former une bobine. A cet effet, le fil (2) est guidé en va-et-vient le long d'une arête de guidage (8), à l'aide d'un dispositif de va-et-vient à ailettes, par des ailettes (6, 7) actionnées en sens contraire transversalement au sens de défilement du fil. La forme de l'arête de guidage détermine la position du fil au niveau de chacune des ailettes de guidage, de manière que le fil soit déposé sur la bobine à une vitesse de va-et-vient prédéfinie. Selon l'invention, la forme de l'arête de guidage (8) peut être modifiée pendant le bobinage, afin que la vitesse de va-et-vient puisse être réduite ou augmentée.
