ABSTRACT:
A conveyor section advances a ribbon into a cutting station where sheets are severed from the glass ribbon. The sheets are advanced onto downstream conveyor rolls where the sheet is accelerated for a given period of time to space the trailing edge of the sheet from the leading edge of the ribbon, i.e., leading edge of the next sheet to be severed from the ribbon. When a predetermined number of spaced sheets are on the conveyor rolls, the conveyor rolls are accelerated to a speed greater than the ribbon conveying speed and spacing speed to move the group of sheets downstream along the conveyor section into additional working stations.
