<p>A continuous method for producing multi-layer coated sheet glass. Molten glass (19) is cast onto a hearth (20) and flows onto the surface of the tin bath (15), from which it is picked up by rolls (22) and conveyed through the lehr (12) and the cooling section (13). A non-oxidizing atmosphere is maintained in zone (18) by introducing a gas thereinto from the conduits (23) to maintain a positive pressure. Nothing is done to control the atmosphere in the lehr; as a consequence, the oxidizing atmosphere therein is air. The glass is treated as it travels under the distributor (27) with a gas containing silane to produce a silicon coating and as it travels under the distributor (28) with an oxidizing gas containing metal compound to form a metal oxide coating. Before the silicon coated glass reach distributor (28) a silicon oxide layer is formed.</p> |
