<p>The present invention relates to a device (1) for locking selectors (4) on the bottom of the needle cylinder grooves (3a) in circular knitting machines. The device (1) comprises a locking element (2) which extends around the needle cylinder (3) of the machine proximate to the lower end of the selectors (4), accommodated in the grooves (3a) of the needle cylinder (3). The locking element (2) is controllably movable in a direction substantially parallel to the axis of the needle cylinder (3) from an inoperative position, wherein the locking element (2) is arranged substantially below the lower end of the selectors (4) to allow the lower end of the selectors to perform an extraction movement from the related groove (3a) in a radial direction with respect to the needle cylinder (3), to an operative position, wherein at least one portion of the locking element (2) is arranged above the lower end of the selectors (4) for their retention in an inserted position in the related grooves (3a), and vice versa.</p> |
