Abstract
A circular knitting machine includes a needle-holding cylinder having plurality of longitudinal grooves arranged around central axis, and plurality of needles, each being housed in longitudinal groove. Drive chain for each needle is inserted into each groove and operatively placed between needle and actuating cams. Drive chain includes sub-needle slidingly arranged in groove and having a butt. Butt is radially movable between operating position, extracted to engage with respective first paths and cause activation of needle and stitch formation, and non-operating position, retracted so as not to engage with first paths. A selector is arranged under sub-needle, and punch is arranged between sub-needle and selector. An activating element is slidingly arranged in groove between sub-needle and selector, can be longitudinally moved with respect to punch and sub-needle, and can be operatively engaged with sub-needle to switch butt of sub-needle into and retain it in operating position.
