 An actuator for use in or with a glassware forming machine for pneumatically driving a member through a predetermined path, such member being, in one embodiment, a pusher cylinder for moving one or more glassware articles through a predetermined arcuate path. The velocity of the actuator is controlled according to a predetermined velocity profile and is effected by an electromechanical control means which controls the linear velocity of the piston of a pneumatic cylinder in one direction of motion.
