METHOD AND APPARATUS FOR FEEDING A GLASS-PLATE HEATING FURNACE

摘要

A device and a process for feeding glass sheets at a predetermined rate to a furnace having a main conveyor moving at a constant speed and extending through the furnace where glass sheets are to be positioned on the main conveyor separated by a predetermined spacing. An auxiliary conveyor moves supply sheets to the entry side of the main conveyor until a supply sheet is temporarily positioned closer to a sheet on the main conveyor than the predetermined spacing at which point the auxiliary conveyor is stopped. A sheet transfer device is provided for then transferring a supply sheet to the main conveyor from the stopped auxiliary conveyor at the speed of the main conveyor when the distance between the last sheet on the main conveyor and the supply sheet is equal to the predetermined distance.
