Abstract

Afin de permettre un changement automatique de bobines pleines dans un dispositif de bobinage à fil entrant de façon continue, il est prévu d'enlever le fil entrant du guide-fil à va-et-vient et de l'acheminer vers un dispositif de coupe et d'aspiration, de couper et aspirer le fil entrant, de faire rouler la bobine pleine, à partir de sa position de bobinage, sur des rails de roulement inclinés, à provoquer, par le roulement de la bobine pleine, la chute d'un tube vide dans la position de bobinage, et à appliquer le fil entrant sur le tube vide acheminé. Un dispositif pour réaliser les étapes de ce procédé présente un rail de guidage de fil mobile (23), un dispositif de séparation de fil (21), une buse d'aspiration de fil (22), des rails de roulement (14) pour la bobine pleine (6), des rails de descente (16) pour un tube vide (18) et un bras de guidage de fil (25) qui place le fil (5) autour du tube vide acheminé.
