Abstract
Forming apparatus (22) and a method for forming a glass sheet ribbon G delivered from a float tank (44) to a topside support device (74) having a downwardly facing surface to which a vacuum and pressurized gas are supplied to support the glass sheet ribbon (G) at its upper surface (52) while a coater (78) applies a coating (80) to its lower surface (54). Another coater (86) applies a coating (88) to the upper surface (52) of the glass sheet ribbon G. A coated glass sheet (32) cut from the glass sheet ribbon G has at least one surface, and as disclosed both of its surfaces (52,54), coated so as to be protected from deterioration caused by exposure to the atmosphere.
