Abstract
A glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The glass sheet formation involves forming a first glass soot layer on a deposition surface of a soot-receiving device, removing the first glass soot layer from the deposition surface, and forming a second glass soot layer on the unsupported first glass soot layer. The resulting composite glass soot sheet is heated to form a sintered glass sheet. The glass sheet can be a substantially homogeneous glass sheet or a composite glass sheet having layer-specific attributes.
Claims16
A method for making a glass sheet, said method comprising:
- depositing glass soot particles on a deposition surface to form a supported soot layer;
- removing the supported soot layer from the deposition surface to form a first soot sheet, the first soot sheet having a contact surface and a free surface;
- guiding the first soot sheet immediately released from the deposition surface by a soot-sheet-guiding device comprising a pair of clamping conveyor belts for depositing a stream of glass soot particles on at least one of the contact surface and the free surface of the first soot sheet to form a composite soot sheet;
- and
- sintering the composite soot sheet to form a glass sheet.
