Abstract
A double cylinder knitting machine has a plurality of pivotable feeders with yarn feeding ends movable through arcs from a trap position, through a feed position to a cross-over park position upstream of the feed position. Movement is imparted to the feeders via a plurality of rotatable cams and cam followers which cause the feeders to pivot upstream of the feed position to an extent sufficient to clear a latchguard and sinkers of the knitting machine followed by further pivotal movement for cross-over and reaching of the park position. The feeders are arrested in predetermined park positions while the cam followers are still on an inclined part of the cams and continued motion of the cams is ineffective after the feeders have reached the park positions.
