摘要： A circular knitting machine includes a needle-holding cylinder having plurality of longitudinal grooves housing plurality of needles, at least one yarn feed operatively associated to needles, actuating cams arranged around and movable relative to cylinder, drive chain for each needle operatively placed between needle and actuating cams. Drive chain includes: sub-needle, selector having butt which can be engaged with selector paths, selecting device acting, punch equipped with butt which can be engaged with punch paths. Punch paths include a tuck stitch ascent and drop stitch ascent for each yarn feed. Inlet of drop stitch ascent circumferentially precedes inlet of tuck stitch ascent. Selector paths include a single track defining first and second ascents placed in succession for each yarn feed. First ascent circumferentially precedes second and is operatively associated to drop stitch ascent and second ascent is operatively associated to tuck stitch ascent.

摘要： A circular knitting machine for manufacturing open-work knitted fabric includes a crown arranged around a needle-holding cylinder and having a plurality of radial grooves and a guiding ring operatively associated to the crown. Each of a plurality of knockover sinkers is housed in one of the radial grooves, is radially movable in the respective radial groove and has a pin configured for cooperating with the needles. At least one shaped sinker is placed beside each of the knockover sinkers and is movable with respect to the respective knockover sinker. The shaped sinker has a protrusion offset laterally with respect to the respective knockover sinker and configured for elongating an interstitch, arranging it on an adjacent needle and forming an open work. A selector is operatively coupled with the shaped sinker and is oscillating in a radial plane between a rest position and an operating position, wherein in the operating position the selector acts indirectly upon the shaped sinker so as to deviate the trajectory of the shaped sinker. A selecting actuator faces laterally the crown and can be engaged upon command with the selectors for causing the selectors to switch from the rest position to the operating position.

摘要： 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.
