Abstract

L'invention concerne un métier à mailles cueillies configuré de manière à ce qu'une vibration d'un tricot qui a lieu lorsque le tricot rentre en contact avec une surface inclinée d'abaissement puisse être minimisée. Un métier à mailles cueillies qui est muni d'un système de cames, qui comprend des plaques de came (100), une came qui élève une aiguille (2), une came supérieure (3) et des cames d'abattage (4), est muni d'une paire de cames pouvant faire saillie (1). Chacune des cames pouvant faire saillie (1) est placée entre une surface inclinée de soulèvement (8) et une surface inclinée d'abaissement (9) afin de pouvoir faire saillie depuis la plaque de came associée. Lorsqu'un tricot (70) est situé sur le côté où le tricot (70) est soulevé par la surface inclinée de soulèvement (8), la came pouvant faire saillie (1) est dans un état rétracté afin de pas gêner le mouvement du tricot (70), et lorsque le tricot (70) est situé sur le côté où le tricot (70) est abaissé par la surface inclinée d'abaissement (9), la came pouvant faire saillie (1) est dans un état déployé de manière à ce que la possibilité de vibration verticale du tricot soit réduite par une surface inclinée de guidage (10) qui fait face à l'extrémité arrière du tricot (70).
