Abstract

L'invention concerne un procédé et un appareil permettant de réaliser des motifs, par commande individuelle de points de guidage destinés à guider les fils constituant les motifs, dans une machine de tricotage sur métier chaîne et d'une plaque d'abattage partielle servant à tricoter lesdits fils pour former une armure tricot à l'aide d'un moyen d'entraînement. Un nombre arbitraire d'unités mobiles comportant des points de guidage sont réparties mobiles le long d'une rangée d'aiguilles à tricoter situées sur le moyen d'entraînement. Lors de la réalisation des motifs, les unités mobiles sont déplacées, d'une distance voulue, le long d'une rangée d'aiguilles à tricoter pour se trouver positionnées de manière à pouvoir exécuter les motifs. On obtient une zone de réalisation de motifs conformément au nombre de points de guidage, ce qui permet de réaliser des motifs variés et libres, correspondant à ceux que l'on pourrait obtenir à l'aide d'un procédé Jacquard. Outre l'exécution de motifs à l'aide de points de guidage, ce système permet en outre d'obtenir des armures sans nécessiter l'utilisation de dispostifs complexes, par déplacement suffisant d'un nombre arbitraire d'unités mobiles comportant des points de guidage et/ou d'un nombre arbitraire d'unités mobiles comportant des plaques d'abattage partiel situées sur le moyen d'entraînement, pour leur faire exécuter des fonctions effectuées sur plaques d'abattage.
