ABSTRACT:
The machine has a needle holder element which has a plurality of grooves. Each groove accommodates at least one needle and one selector which faces, with one of its longitudinal ends, the base of the needle. Each needle has at least one heel which protrudes from the related groove of the needle holder element and is engageable in paths defined by cams which face the needle holder element, in order to actuate the needles with a reciprocating longitudinal motion along the grooves for forming knitting. Each needle is oscillable in a plane which is substantially parallel to the sides of the related groove for the passage of its heel from a position in which it is sunk in the groove to an extracted position in which it protrudes from the related groove. An extraction element is provided in each of the grooves between the selector and the related needle and is controllably movable from an inoperative position, in which it does not interfere with the position of the needle, to an operative position, in which it defines a rest for the side of the needle which is opposite to its heel so as to keep the heel in an extracted position.
