Abstract
This device for the selection of the needles comprises a selector accommodated below a needle in a same groove of a needle bed of the machine. The selector is controllably movable from an extraction position, in which a heel thereof protrudes from the groove to engage with selection cams facing said needle bed, to a sunk position, in which the heel is accommodated in the groove so as to not engage with the selection cams. Between the selector and the bottom of the groove an elastic element is interposed which keeps the selector in the extraction position and a sinking cam is provided, rigidly associated with the selection cams, which causes the passage of the selector from the extraction position to the sunk position in contrast with the elastic element. A rod is engageable with the elastic element to keep the selector in the sunk position and actuators controllably act on the rod to cause disengagement thereof from the elastic element so as to obtain the passage of the selector to the extraction position.
