Programming device for circular stocking knitting machines and the like

摘要

Wide variations of the knitting program determined by the program drum of a circular knitting machine may be achieved by providing a plurality of rotatable program discs having peripheral seats for removable pins for determining supplementary programs and by providing followers co-operable with the program discs and linked to the means for advancing the program drum to selectively render the advancing means inoperative in dependence on the supplementary program. A driving linkage actuated by a cam track on the program drum is provided to allow relatively large angular advancement of the program drum when desired. Another driving linkage actuated by another cam track on the program drum is provided for reducing the speed of the needle cylinder.
