ABSTRACT:
In a circular knitting machine, needle selection is controlled by pattern keys mounted on a pivoted pattern key carrier and having patterning butts which are selectively engageable with vertically stacked selector slides. The selector slides are engageable selectively with selector butts on pressers associated with needle jacks. When a presser is engaged by a selector slide the corresponding jack is pressed in so that a control butt on the jack is not engaged by a needle-operating cam. Pivoting of the pattern key carrier is controlled by a boat-shaped cam follower which is carried on an arm on the pattern key carrier and travels in one or another of circular tracks concentric with the needle cylinder. Means is provided for switching the cam followers from one track to another, thereby pivoting the pattern key carrier to bring other pattern keys into engagement with selector slides.
