ABSTRACT:
A needle selection device in a circular knitting machine, including: needles which are slidingly accommodated in grooves formed in a needle holder and which have pivoting levers provided with heels; needle actuation cams facing the needle holder and forming a path which can be engaged by the heels of the needle levers as the needle holder moves with respect to the needle actuation cams in order to make the levers follow the path for actuation of the corresponding needle along the corresponding groove of the needle holder parallel to the longitudinal extension of the needle, and for each needle the lever oscillates about its pivoting axis, from an active position, in which its heel protrudes from the corresponding groove of the needle holder so as to engage the path formed by the needle actuation cams, to an inactive position, in which its heel is inserted in the corresponding groove of the needle holder in order to avoid engaging the path formed by the needle actuation cams; a reset element acting on the lever of each needle to move it from the active position to the inactive position; an electromagnetic device facing a ferromagnetic portion of the lever for each needle and actuated on command to keep the lever in the inactive position or to move it into the active position.
