ABSTRACT:
A sheet of glass is bent with a system including a feed mechanism for feeding the sheet of glass along a predetermined path, a heating furnace disposed along the path, for heating the sheet of glass, and a shaping device disposed along the path for bending the sheet of glass heated by the heating furnace. Before the sheet of glass is bent by the shaping device, the sheet of glass is thermally processed to different degrees at leading and trailing end portions thereof along the path, thereby uniformizing temperatures of the sheet of glass from the leading end portion to the trailing end portion thereof.
