Abstract
The present invention relates to a heating apparatus for glass-sheet-forming, which prevents formation of a heater distortion in a portion of a glass sheet facing to a temperature-distributing heat shield. A heating apparatus for glass-sheet-forming comprising a heating element for heating a glass sheet, a heat-shielding plate for partitioning a heating region Y into a plurality of regions X and partially shielding radiant heat rays radiated from the heating element toward the glass sheet so as to form a predetermined temperature distribution on a surface of the glass sheet heated by the heating element, wherein the heating apparatus for glass-sheet-forming further comprises an auxiliary heat-shielding plate for partially shielding radiant heat rays radiated from a heating element toward a portion of the surface of the glass sheet, that faces to the heat-shielding plate, as a heat-ray-adjusting means for reducing radiant heat rays from the heating element reaching a portion of the surface of the glass sheet that faces to the temperature-distributing heat shield.
