Abstract:
1. 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: a heat-insulating member is disposed facing the glass sheet immediately below the forming body, and a facing surface of the heat-insulating member 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 member is substantially uniform; the heat-insulating member has members which are independent of each other and correspond to a center portion and both end portions of the glass sheet; the heat-insulating member is disposed between the forming body and a cooling roll for cooling an end portion of the glass sheet and suppressing shrinkage thereof in the width direction; and the members of the heat-insulating member are in contact with each other, wherein the gap between the glass sheet and the heat-insulating member is substantially uniform across the width of the glass sheet including both end portions of the glass sheet.
