ABSTRACT:
A first molten glass of one composition is caused to flow downwardly along converging flow paths of a forming member while simultaneously at least one other molten glass of a different composition is flown downwardly along outer surface portions of the first glass such that said glasses are in molten contact with one another during their downward travel and are then continuously formed into a composite or laminated glass sheet. The molten glasses are distributed to the forming member in such a manner as to provide substantially uniform thickness of the glass layers across the newly formed sheet, and various viscosity, glass flow rates and proportionate layer thicknesses may be obtained by varying the degree of tilt of the forming member.
