Abstract
A method of applying a metallic oxide coating to a moving ribbon of glass is disclosed for four thicknesses of glass, namely, 7/32; 3/16; 5/32 and 1/8 inch. In each of these methods, first and second spray zones are established at opposite edges of the moving ribbon. The spray zones are moved in a simultaneous manner at the same speed from one edge to the other edge whereby the spray zones pass each other at the center line of the moving ribbon. When each of the spray zones reach the opposite edge of the moving ribbon, their direction of travel is reversed so that they once again pass one another at the center line of the moving ribbon. The first and second spray zones are spaced a slight distance from one another in the direction of movement of the moving ribbon. The moving spray zones are cycled back and forth in the aforedescribed manner continuously as the ribbon of material is moved thereunder so that a coating is applied to the moving ribbon. This method is used for applying a metal oxide coating to a moving ribbon of glass which is emerging from a float glass chamber.
