Abstract

A method and apparatus is disclosed for the production of plate glass. A glass melting furnace containing molten glass connects with an outflow furnace in such fashion that central layers of molten glass in the glass melting furnace are conveyed to the outflow furnace. The outflow furnace connects with an outflow nozzle which forms a flat glass band from which the plate glass is cut. The outflow speed of the glass band issuing from the outflow nozzle is regulated by a static pressure adjustment determined by a height of the molten glass in the separate outflow furnace. A supply channel to the nozzle preferably contains heating electrodes for resistance heating of the molten glass prior to issuance from the nozzle.
