Abstract

L'invention concerne un dispositif délivreur de fil (1) à palpeur de fil amélioré. Le palpeur de fil (18) et un guide-fil associé (12) y constituent de préférence un ensemble qui peut être déplacé parallèlement à l'axe de rotation de la roue délivreuse de fil (3). Le palpeur de fil (18) comprend un levier (19) ou autre élément qui est de préférence disposé en position verticale. Cet élément s'étend ainsi en éloignement du fil dans une première direction transversale. Dans une première forme de réalisation, cet élément est mobile dans une seconde direction transversale (direction de pivotement), tandis que dans une seconde forme de réalisation, il est monté à translation longitudinale. Comme le mouvement du palpeur de fil est orienté exclusivement transversalement et de préférence perpendiculairement au fil, les impulsions de déplacement agissant sur le palpeur sont minimisées. La disposition verticale du palpeur de fil permet en outre d'utiliser le palpeur pour une très large plage d'épaisseurs de fil, allant du fil polyester le plus mince aux épais fils fantaisie.
