ABSTRACT:
The present invention relates to improvement in a method of supplying a glass ribbon in a molten state to be supplied from a glass melting furnace to a flat glass forming apparatus, which can further improve the smoothness of a flat glass after formed. A glass ribbon13supplied from a glass melting furnace14to a flat glass forming apparatus15is stretched between one pair of tension rollers24A and24B in an S-shape and the tension rollers24A and24B are rotated while applying a surface pressure to the glass ribbon13face via a thin layer of a steam film generated by vaporization of a steam film forming agent. By means of rotation of the tension rollers24A and24B, the face of the glass ribbon13still in a molten state is polished via the steam film18.
