摘要

A method for manufacturing a curved sheet of glass which includes a heating furnace for heating a sheet of glass therein, the heating furnace having an outlet opening for discharging a curved sheet of glass, and an array of beds housed in the furnace for transferring a sheet of glass successively over the beds in the furnace in a first direction toward the outlet opening while shaping the sheet of glass complementarily to an upper surface of the beds, each of the beds having a plurality of hot air ejecting holes for ejecting hot air to keep the sheet of glass out of contact with the beds, the beds including a final bed disposed near the outlet opening and inclined upwardly toward the outlet opening, the final bed having an upper panel including at least a portion curved in the first direction near the outlet opening to curve the sheet of glass in the first direction.
