<p>Molten glass 1 flows continuously from a glass melting furnace 2 to a drawing tank 7 when the glass is drawn as a continuous ribbon 10 and is passed over a bending roll 13 in a drawing chamber 8 above the tank 7 and then to a horizontal annealing lehr 14. A high yield of glass, especially thin glass, of a high standard of thickness uniformity and good planeity is promoted and facilitated by causing the molten glass 1 to flow upwardly through a slot 11 in a refractory device 12 partially immersed in molten glass in a deep drawing tank.</p> |
