Abstract
For positioning a glass sheet moving on a conveyor, two substantially identical assemblies are positioned on opposite lateral sides of the conveyor. Each of the assemblies includes an arm carrying an abutment and extending in proximity to the conveyor such that a glass sheet moving on the conveyor will contact the abutment and be prevented from movement along the conveyor beyond the abutment. Contact between the glass sheet on the conveyor and an abutment will cause the abutment to move slightly, so that such contact can be detected. When the glass sheet contacts both abutments, the arms are driven for permitting passage of the glass sheet.
