Abstract

Afin de réaliser un changement le fil (F) dans les limites d'une course de fil (H) d'une bobineuse (1), à l'aide d'un guide-fil en forme de pointeur, ci-après dénommé pointeur, à une vitesse élevée, le pointeur est effilé vers l'extrémité libre de façon correspondante en termes de forme et de poids. Dans un mode de réalisation préféré, on utilise un polynôme d'au moins un degré. En plus, le fil est guidé sur une règle de guidage (6). La commande (12) du moteur (8) est prévue de telle façon que le pointeur (7) ne sert pas uniquement au guidage du fil (F) dans les limites de la course de fil (H) mais aussi, d'une part, le pointeur s'arrête dans un position (C) dans les limites de la course de changement (H) pour former un bourrelet terminal sur une bobine finie et, d'autre part, il s'arrête dans une position (A) et dans une position (B) en dehors des limites de la course de changement (H) de telle façon que, dans la position (A), le fil soit saisi par une nouvelle douille à l'entrée (8) pendant le changement de bobine puis, dans la position (B), le fil soit enroulé sur la douille pour constituer une bobine de réserve avant d'être à nouveau ramené dans la course (H) par le pointeur (7). Les points d'inversion souhaités peuvent être introduits dans la commande. La commande et le moteur coopèrent pour inverser le pointeur en un point d'inversion choisi. Un moyen d'inversion, prévu à cet effet, fonctionne sans contact, par exemple, par voie électromagnétique.
