Needle control device for stocking knitting machines

Abstract

A needle control device for stocking knitting machines, comprising a connecting element which can engage a needle or sub-needle or slider and can be arranged in the same slot of the needle holder that accommodates a needle, and an actuation element which is connected to the connecting element and can oscillate on command on a plane which is substantially parallel to the sides of the corresponding slot of the needle holder in which it is accommodated. The actuation element is provided with at least one first heel and at least one second heel which are mutually spaced along the side of the actuation element that lies opposite the side meant to be directed toward the bottom of the slot of the needle holder. The actuation element is movable, as a consequence of its oscillation, into three positions, respectively a first position, in which the heels are both inserted in the corresponding slot of the needle holder, a second position, in which the first heel protrudes from the slot of the needle holder while the second heel is inserted in the slot of the needle bolder, and a third position, in which the first heel is inserted in the slot of the needle holder while the second heel protrudes from the slot of the needle holder.
