Abstract: An apparatus and method for manufacturing a glass sheet are disclosed. The apparatus includes a glass delivery device, a puddle forming device positioned to contact and redirect at least a portion of a stream of molten glass as it falls from the glass delivery device, and a side roller configured to contact the stream falling from the glass delivery device and redirected from the puddle forming device at a target position and lose contact with the stream at a departure position to form a ribbon of glass. The puddle forming device and the side roller can be relatively positioned to form a puddle of molten glass on a surface of the side roller positioned upstream from the target position and a thickness control gap between the puddle forming device and the side roller.

Abstract: According to one embodiment, a method of forming a laminated glass ribbon may include flowing a molten glass core composition and a molten glass cladding composition in a vertically downward direction. The molten glass core composition may be contacted with the molten glass cladding composition to form the laminated glass ribbon comprising a glass core layer formed from the molten glass core composition and a glass cladding layer formed from the molten glass cladding composition. Core beads located proximate an edge of the glass core layer and clad beads located proximate an edge of the glass cladding layer may be compressed while the glass core layer and the glass cladding layers have viscosities greater than or equal to the viscosity at their softening points as the laminated glass ribbon is drawn in the vertically downward direction.
