PROBLEM TO BE SOLVED: To solve the problem that when molten glass is subjected to roll-out molding, several visible stripes are produced easily in the traveling direction of a glass ribbon if the glass ribbon is widened. SOLUTION: The method for molding sheet glass, in which the molten glass falling from a molten glass feeder is made to pass through the space between paired rolls, comprises the steps of: forming the roll from a base material which consists of a material enough to involve a liquid therein or has a structure enough to do so; arranging the rolls to be paired below the molten glass feeder to constitute a highest roll pair; rotating the paired rolls to mold the glass ribbon between the paired rolls while interposing a vapor curtain of the liquid between the molten glass and the roll; discharging the molded glass ribbon downward; heating the edges of the discharged glass ribbon; and rolling the resulting glass ribbon between one or more roll pairs arranged right below the highest roll pair.
