Abstract

La présente invention concerne un dispositif (1) de production de fils fantaisie lors de la texturation du filé par réalisation d'une flambure pendant une brève période d'excès de fourniture de filé, qui comporte un entraîneur linéaire motorisé (4) capable de s'écarter du parcours du fil (35). Cet entraîneur (4) comporte un guide-fil (9) utilisé pour créer un manque de fil en saisissant un fil (2) du filé avec le guide-fil (9) et en écartant ce fil de son parcours de fil (35). À cet effet, le dispositif selon l'invention comporte des organes de déclenchement (10) configurés pour dégager le fil (2) du guide-fil (9) en un point de déviation situé sur le côté du parcours du fil (35) de façon à produire un excès de filé par une brusque interruption de la déviation du filé. Les organes de déclenchement (10) sont constitués d'une rampe disposée de façon que le fil (2) puisse être poussé sur la rampe au moyen du guide-fil (9) au niveau du point de déviation. Lorsque le fil (2) est poussé pour se dégager, il se soulève du guide-fibres (9) et/ou en sort en se soulevant. Le fonctionnement du dispositif est indépendant de la tension du fil.
