Abstract

La présente invention concerne une tricoteuse de trame avec une platine mobile capable de former une dent supérieure en maintenant fermement un câble d’arrêt de fil à tricoter. Dans une entretroise de guide-fil (17), une section de guide-fil (17a) en saillie vers la bouche dentée (13) est pourvue d’un trou de coulée (17b) et un trou débouchant (17c) est prévu sur le côté de bord inférieur du trou de coulée (17b). Le câble d’arrêt du fil à tricoter (21) pénètre le trou débouchant (17c) dans la direction longitudinale d’une fonture (12). Même si le câble d’arrêt du fil à tricoter (21) pénètre, en tant que dent supérieure, dans la direction longitudinale au niveau de l’extrémité distale sur le côté de la bouche dentée (13) de la fonture (12), un déplacement oscillant de la platine mobile (16) est assuré en prévoyant un trou arqué oblong (16d) au niveau de la partie de bras arqué (16c) de la platine mobile (16).
