Abstract

L'invention concerne un ensemble cylindres, qui comprend un cylindre d'entraînement à axe fixe et un cylindre entraîné à axe mobile, dans lesquels une tête de serrage d'entraînement et une tête de serrage entraînée, chacune étant revêtue par un matériau mou, sont disposées respectivement au-dessus du cylindre d'entraînement et du cylindre entraîné, chaque extrémité de l'arbre du cylindre d'entraînement étant raccordée à un vilebrequin pouvant tourner autour de l'axe du cylindre d'entraînement avec trois manivelles; les première, deuxième et troisième manivelles faisant saillie à partir du cylindre d'entraînement. La première manivelle est raccordée à la tête de serrage entraînée, et la deuxième manivelle est pourvue d'une encoche traversante conçue pour permettre au cylindre entraîné de passer et de se déplacer dans celle-ci. Une came est disposée sur le côté de la troisième manivelle vers la partie saillante de la deuxième manivelle, laquelle exerce une pression sur la troisième manivelle lorsqu'elle est mise en rotation jusqu'à une certaine position. Des ressorts sont raccordés à des extrémités de l'arbre du cylindre entraîné, et appliquent une force de traction vers le cylindre d'entraînement. Le cylindre d'entraînement et le cylindre entraîné sont positionnés à une courte distance de la partie coin de la plaque à tricoter, et s'ouvrent de manière triangulaire vers le haut, ce qui permet de faire des économies de fil à tricoter initial, de faciliter le transfert des multiples aiguilles mobiles, et d'obtenir ainsi un processus de tissage stable au moyen d'une butée ajustée entre le cylindre d'entraînement et le cylindre entraîné pendant les mouvement d'ouverture et de fermeture.
