<p>Selector devices are mounted on the stator of a circular knitting machine at the knitting stations. Each selector device includes a set of selector slides which have an actuating position for moving jacks to an ineffective position. A single preselecting device rotates with the needle cylinder and has a set of preselector slides which are selectively shifted to and from an operative position by reversible electromagnets energized in accordance with a desired knitting pattern. Preselector slides in the operative position shift the correlated selector slides of all selector devices successively to the actuating position displacing the respective jacks.</p> |
