Abstract

See full text

Provided is a sheet glass production process for properly producing sheet glass having a convex shape in section in a width direction orthogonal to the advancing direction of a glass ribbon. A glass ribbon G2 advancing on molten metal 22 is heated so as to have both edge portions G2B heated more intensely than a central portion G2A in a width direction thereof in an upstream zone of the molten metal bath, and a plurality of rolls 23 are rotated in contact with both edge portions G2B of the glass ribbon G2 such that upstream rolls 23A in an advancing direction F1 have a lower peripheral speed than downstream rolls 23B in the advancing direction.
