Abstract
A programmable, microprocessor-based controller is responsive to a displacement command signal and first and second transport signals corresponding to the distance that glass sheets are conveyed on main and auxiliary conveyors, respectively, to provide a speed control signal to a separate, variable speed drive. The variable speed drive drives the auxiliary conveyor independently of the driven main conveyor. The variable speed drive is controlled by the controller to: (1) reduce the rate of glass sheet conveyance; (2) reposition the leading and trailing glass sheets, if necessary, along the direction of conveyance; and (3) insure that as each glass sheet is transferred between the main conveyor and the auxiliary conveyor, the auxiliary conveyor is driven at the same speed as the main conveyor.
