Abstract (en)
A circular knitting machine (20) comprises rotary needle cylinder, knitting needles, spring jacks, selector jacks (24) and a multi-tier electrically controlled needle selecting device (30). The needle selecting device (30) includes piezoelectric elements (32) and pattern fingers (33) for selecting and causing the selector jacks (24) control the movement of the needles (22) between welt, tuck and knit positions. A pre-pusher cam (34) is provided paritally to push the selector jacks (24) inwardly before these selector jacks are engaged by the pattern fingers (33) which increases the range of selection and permits increased speed in fine gauge knitting machines (24 gauge and higher) and which permits a reduction in the number of piezoelectric elements in coarse gauge machines and the inclusion of an interlock jacquard apparatus. <IMAGE>
