Abstract
According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt (300) from a molten core glass (106) and at least one molten cladding glass (126). The multi-layer glass melt (300) has a width Wm, a melt thickness Tm and a core to cladding thickness ratio TC:TCl. The multi-layer glass melt (300) is directed onto the surface of a molten metal bath (162) contained in a float tank (160). The width Wm of the multi-layer glass melt (300) is less than the width Wf of the float tank (160) prior to the multi-layer glass melt (300) entering the float tank (160). The multilayer glass melt (300) flows over the surface of the molten metal bath (162) such that the width Wm of the multi-layer glass melt (300) increases, the melt thickness Tm decreases, and the core to cladding thickness ratio TC:TCl remains constant as the multi-layer glass melt (300) solidifies into a laminated glass sheet. The invention also relates to the associated apparatus.
