Abstract

L'invention fournit un procédé de couture de tricot pour tricoteuse circulaire, et un système de tricoteuse circulaire qui rendent une portion liaison aussi fine que d'autres mailles. Les aiguilles de déplacement (34) pénètrent dans la direction axiale des aiguilles de tricotage (21), et les aiguilles de déplacement (34) et les aiguilles de tricotage (21) se trouvent en continuité dans la direction axiale. Une saillie d'extrémité avant (34e) des aiguilles de déplacement (34) est décalée côté interne. Une platine de déplacement (49) est déplacée dans la direction axiale des aiguilles de tricotage des aiguilles de tricotage (21) vers les aiguilles de déplacement (34). Les saillies d'extrémité avant (34e) des aiguilles de déplacement (34), sont introduites dans des mailles côté interne (26a) positionnées côté interne du tricot (27) par rapport à des mailles finales (26) attachées aux aiguilles de tricotage (21), et le tricot (27) est déplacé des aiguilles de tricotage (21) vers les aiguilles de déplacement (34). Les mailles côté interne (26a) déplacées vers les aiguilles de déplacement (34), sont liées. La taille des mailles de liaison est plus petite que la liaison effectuée par déplacement des mailles finales vers les aiguilles de déplacement. Il est possible de rendre la portion liaison aussi fine que les autres mailles, et d'améliorer ainsi la durabilité et les qualités esthétiques.
