Abstract

See full text

In an annealing zone (3) of a glass sheet producing method, a curved portion (5) is formed by curving a glass ribbon (G) in a width direction, and a concavo-convex direction in a front and back direction of the curved portion (5) is reversed at least between an upper side and a lower side of a part of a region in the width direction of the glass ribbon (G). Therefore, a bending resistance in an upper and lower direction of the glass ribbon (G) and a bending resistance in the width direction of the glass ribbon (G) are increased.
