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.

Coating method

This disclosure is directed to a machine for applying a spray coating across the width of a glass ribbon. The glass ribbon is one which generally has recently been manufactured and is carried on a conveyor moving below the machine. In accordance with the preferred teachings of this apparatus, two spray applying devices are used. These devices commence their spraying at opposite edges of the moving ribbon of glass. The devices are moved in a simultaneous manner at the same speed from one edge to the other edge of the glass ribbon whereby the apparatus pass each other at the center line of the moving ribbon. When each of the spray apparatus reach the opposite edge of the moving ribbon of glass, 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 apparatus are spaced a slight distance from one another in the direction of movement of the ribbon of glass. The moving spray apparatus are cycled back and forth in the aforedescribed manner continuously as the ribbon of glass is moved thereunder so that a coating is applied to the moving ribbon of glass.
