| Zusammenfassung: | Needles selection appts. for a circular knitting machine (1) comprises needle jacks (3) operable by movable plungers (19a, b) on respective piezoelectric actuators (17,18) mounted in holers (14) fixed radially outwardly of the cylinder contg. the slidable jacks (3). Movements of plungers (19a, b) is translated (21, 21c) into jacks (3) movements, specifically by pivotal selector levers (21) controlled also by holding magnets (20a) through which two plungers (19a, b) are projectable to pivot each lever (21) bidirectionally. Each actuator (17,18) comprises a stack of flat piezoelectric elements. |
