Glass containers are transferred from the dead plates of a forming machine of the I.S. type to an adjacent machine conveyor by 90.degree. sweepouts, each of which is powered by an a.c. servo motor. The machine conveyor, which is also powered by an a.c. servo motor, conveys containers to a cross-conveyor, which extends perpendicularly to the machine conveyor and conveys the containers to positions adjacent the inlet of an annealing lehr. The transfer of containers from the machine conveyor to the cross-conveyor is effected by a chain transfer device, and the cross-conveyor and the chain transfer device are each powered by an a.c. servo motor. Groups of containers are transferred in unison from the crossconveyor to a moving conveyor of the annealing lehr by the reciprocating pusher bar of a lehr loader, and the operation of the lehr loader pusher bar which reciprocates along three (3) axes, powered by three (3) a.c. servo motors. The operation of each of the a.c. servo motors for the 90.degree. sweepouts, the machine conveyor, the cross-conveyor, chain transfer device and the lehr loader pusher bar, and the operation of the annealing lehr, which is powered by an a.c. motor, conveyor is simultaneously measured and controlled to process containers at all times from the forming machine dead plates to the annealing lehr conveyor at predetermined controlled rates.
