PROBLEM TO BE SOLVED: To reduce heat loss from an edge director provided to help achieve a desired glass sheet width and edge bead characteristics. SOLUTION: The method includes steps of: flowing a molten glass over a pair of downwardly inclined forming surface portions 66a and 66b of a forming wedge 62 converging along a downstream direction to form a root portion 70; flowing the molten glass over an edge director 80a intersecting with at least one of the pair of downwardly inclined forming surface portions 66a and 66b; drawing the molten glass from the root portion 70 of the forming wedge 62 to form a glass sheet 12; and reducing heat loss from the edge director 80a with the use of a thermal shield 120a.
