Claims (8)

  1. Dispositif de freinage de fil pour métiers à tisser, qui comprend un boîtier principal (26) qui soutient une triade d'oeillets (32, 34, 36) de guidage de fil qui sont traversés par un fil de trame (F) et un élément de freinage (58) en forme de U qui est fixé à des moyens motorisés (40) et qui chevauche l'oeillet central (34) de manière à engager pendant le freinage le fil (F) par ses longueurs libres situées entre l'oeillet central (34) et les oeillets d'extrémité (32, 36) pour ainsi être amenés à freiner le fil (F) par frottement, caractérisé en ce qu'au moins l'un des oeillets d'extrémité (32, 36) est porté par un support déplaçable axialement qui peut être verrouillé en une position axiale prédéterminée.
  2. Dispositif selon la revendication 1, caractérisé en ce que lesdits deux oeillets d'extrémité (32, 36) sont maintenus par les supports respectifs déplaçables axialement.
  3. Dispositif selon la revendication 2, caractérisé en ce que lesdits supports déplaçables axialement sont constitués de deux douilles filetées (42, 46) qui engagent les extrémités opposées contre-filetées d'une broche (44) soutenue à pivotement sur ledit boîtier principal (26).
  4. Dispositif selon l'une quelconque des revendications précédentes, caractérisé en ce qu'il comprend des guides de retenue (54) adaptés pour guider la translation des oeillets d'extrémité (32, 36) par rapport au boîtier principal (26) tout en empêchant leur rotation.
  5. Dispositif selon la revendication 4, caractérisé en ce que lesdits guides de retenue comprennent une tige (54) parallèle à la broche (44) et formée d'un seul tenant avec l'oeillet central (34) et dont les extrémités engagent par glissement des trous respectifs ménagés sur les oeillets d'extrémité (32, 36).
  6. Dispositif selon la revendication 3, caractérisé en ce que ladite broche (44) est dotée sur sa tête d'un moyen d'engagement qui peut être engagé par un outil pour faire tourner la broche (44).
  7. Dispositif selon la revendication 6, caractérisé en ce que ledit moyen d'engagement est constitué d'une rainure (50) qui peut être engagée par un tournevis.
  8. Dispositif selon l'une quelconque des revendications précédentes, caractérisé en ce que ledit moyen motorisé est un moteur rotatif (40) fixé au boîtier principal (26), ledit élément de freinage (58) étant fixé radialement sur l'arbre (38) dudit moteur rotatif.
