ABSTRACT:
An glass manufacturing process and apparatus having a vertical air-cooled electric furnace and a transverse air-cooled refiner section. The furnace and the refiner are provided with a plurality of molybdenum plate electrode cartridge assemblies. Molten glass is removed from the furnace refiner section by means of a plurality of basin cylinders symmetrically disposed within the transverse refiner. An extruder mechanism accepts molten glass from each basin cylinder and applies the molten glass to a pair of extrusion rolls and onto a molten tin bath. The extrusion rolls are eccentrically pivoted off-center such that the separation distance between them can be varied. A cutting frame is then lowered over the tin bath such that the molten glass sheet is held firmly while it is cut into lite sizes by a cutting mechanism. After cutting, a transfer unit having suction orifices is lowered over the glass sheet and lifts the newly cut glass sheet either to an annealing stage or to a tempering stage. The cut glass sheet then undergoes electronic inspection and packaging.
