Disclosed is a sinker for a circular knitting machine being characterized by two symmetrical L-shaped recesses formed at two lateral sides of an upper half of a front top portion of the sinker, including a nose and a nose slot formed above the portion. The L-shaped recesses are so formed that, when the sinker is moved into a corresponding channel on the needle cylinder in front of the sinker, the recesses are located slightly above the channel. When the sinker reciprocates back and forth to together with the up and down latch needle form and knit piles, dust so produced settles on the L-shaped recesses and is removed therefrom without falling into and cumulating in the channel of the needle cylinder due to the movements of the sinker at high speed. The cleaning of needle cylinder and sinkers can be minimized and the quality of knitted fabrics can be enhanced with the arrangement of such L-shaped recesses on two sides of the sinker.

La présente invention se rapporte à une platine de métier circulaire se caractérisant par deux encoches en forme de L pratiquées dans deux côtés latéraux, dans la moitié supérieure de la portion avant supérieure de la platine, ainsi que par un mentonnet et une fente de mentonnet formée au-dessus de ladite portion. Les encoches en forme de L sont conçues de manière à ce que lorsque la platine est amenée dans le canal correspondant du cylindre d'aiguilles, placé devant ladite platine, elles se retrouvent légèrement au-dessus du canal. Lorsque la platine se déplace dans un mouvement de va-et-vient avec la forme ascendante et descendante d'aiguilles à clapet et les poils, la poussière ainsi produite retombe sur les encoches en forme de L et est éliminée sans obstruer le canal du cylindre d'aiguilles sous l'action des mouvements rapides de la platine. Le fait de prévoir des encoches en forme de L sur deux côtés de la platine permet de réduire au minimum le nettoyage du cylindre d'aiguilles et des platines et améliore la qualité des tricots produits.
