ABSTRACT:
In a substantially horizontal conveyor or conveying heated glass sheets, a positioning device for aligning the sheets in a direction transverse to the conveying direction. It includes thrust rods advanced by the engagement of cam followers moving with the thrust rod on cams stationary with respect to the conveyor. Draw springs return the thrust rods to their initial position. The thrust rods are mounted on crosswise carriages, which are in turn mounted on carriages movable in the conveying direction and in synchronism with the glass sheets. The thrust rods are pivotally mounted on the crosswise carriages about horizontal axes, and so their distal ends can be displaced out of the plane of the glass sheets during the return movement of the carriage.
