Patent ID: 8826694

Claim:
A method of manufacturing a glass sheet, comprising the steps of creating split flows of molten glass in a forming body and causing the molten glass to flow down, subsequently merging the flows at a merging point to form a glass sheet and causing the glass sheet to flow downward in the vertical direction; the method of manufacturing a glass sheet characterized in that there are provided a plurality of chambers separated by heat-insulating plates in the direction of movement of the glass sheet, and a heater for controlling the temperature of the chamber is provided for each of the chambers so that the temperature of the chamber decreases in order in the direction of movement of the glass sheet; and the heat-insulating plate is disposed facing the glass sheet, and a facing surface of the heat-insulating plate is shaped so as to correspond to a sheet thickness variation of the glass sheet, so that a gap between the glass sheet and the heat-insulating plate is substantially uniform.
