Abstract
A beam carries two abutments and is moveable on the conveying direction of the conveyor. Starting from rest, the beam is accelerated to a speed less than that of the glass sheet moving on the conveyor, so that the glass sheet contacts the abutments while both are moving along the conveyor. Once the glass sheet is correctly oriented, the beam is accelerated and raised to permit the passage of the glass sheet. The beam is then retracted to the initial position for the next cycle of operation.
