Abstract
A method of manufacturing a glass sheet according to the present invention comprises the steps of creating split flows of molten glass in a forming body 10 and causing the molten glass to flow down, subsequently merging the flows at a merging point to form a glass sheet G and causing the glass sheet to flow downward in the vertical direction. In this method of manufacturing a glass sheet, a partition member 20 is disposed facing the glass sheet G in the vicinity of a location below the forming body 10, and a facing surface of the partition member 20 is shaped so as to correspond to a sheet thickness variation of the glass sheet G, so that a gap between the glass sheet G and the partition member 20 is substantially uniform.
Claims12
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.
