Abstract

L'invention concerne un dispositif de mouvement de jeté de barre de guidage pour machine à tricoter en chaîne. Le dispositif comporte un siège de barres de guidage (1), une pluralité de barres de guidage (3), des rails de guidage (2), des aiguilles à trou (4) et des dispositifs d'arrêt. La fixation par soudage entre l'aiguille à trou et la barre de guidage est remplacée par une fixation par boulon obtenue en disposant les alésages vissés (10) sur les barres de guidage. Des trous sont disposés sur l'extrémité supérieure d'une aiguille à trou; les extrémités supérieures des aiguilles à trou sont ajustées sur les barres de guidage par des boulons (7) et les trous prévus. Des rails de guidage (8) sont disposés sur les deux côtés des rails de guidage auxquels correspondent des rainures coulissantes (9) disposées sur les barres de guidages; les barres de guidage sont ajustées entre les rails de guidage par les rails coulissants. Des contre-alésages sont disposés sur les barres de guidage auxquels correspondent des trous vissés disposés sur le siège de barre de guidage; les rails de guidage, agrippant la barre de guidage, sont fixés de façon transversale sur le siège de barre de guidage par des boutons par les contre-alésages et des trous vissés. Les aiguilles à trou peuvent être facilement et rapidement fixées, désassemblées ou remplacées. L'utilisateur peut changer le piquage de façon opportune; la structure du dispositif de mouvement de jeté de barre de guidage est simple et la durée de vie longue. Plus de barres de guidage peuvent être assemblées.
