Abstract

La présente invention a pour objet un porte-fil pour retenir un fil lors de la production d'une bobine de fil à enrouler avec ce fil, en particulier pour retenir une extrémité du fil lors du changement de bobine de fil, doté d'une bague de serrage (20) pour serrer le fil. La bague de serrage (20) comporte deux mâchoires de serrage (22, 23) essentiellement annulaires et les mâchoires de serrage (22, 23) entourent un arbre d'entraînement (25) rotatif pour une bride d'entraînement (1) d'un logement de tube pour la bobine de fil. Selon la présente invention, ledit porte-fil comprend un entraînement électromagnétique qui est conçu de manière à pousser l'une vers l'autre les mâchoires de serrage (22, 23) pour serrer le fil, de préférence avec une composante de force dans la direction axiale de l'arbre d'entraînement (25).
