An optimization bench for glass plates is configured to move the plates in a longitudinal direction of the bench in order to arrange the plates in positions suitable to achieve optimal occupation of the available area on the bench. The bench includes a plurality of belt conveyors parallel to each other, selectively driven by motor means through a plurality of electrically operated clutches which are respectively associated with the belt conveyors. An electronic controller is configured to convey each plate by activating only the belt conveyors on which the plate rests, until all plates are arranged in an optimized manner on the bench area.
