Abstract
A process for coating a ribbon of float glass is disclosed. It comprises the steps of forming a glass ribbon, depositing a first transparent conductive coating upon a major surface of the ribbon which does not extend to the edges of the ribbon while the ribbon is at an elevated temperature, cooling said coated ribbon under controlled conditions in an annealing lehr and cutting off the edges of the ribbon so as to produce a ribbon having a uniform coating extending across the full width of the cut ribbon which is characterized in that a second conductive coating is deposited upon the uncoated edges of the ribbon while that edge is at a temperature which is above the ambient temperature. The invention finds particular application in the production of coated glass products where the thickness of the glass ribbon is at least 8 mm and most particularly where the thickness of the glass is at least 10 mm.
