Method for the manufacture of ribbon-shaped flat glass, of a melting glass layer established in a bath of molten metal, whose method comprises the operations of keeping the glass in a state of fusion as it progresses through the bath, subjecting the glass at a controlled tensile stress in the direction of advance along the bath and at the simultaneous action of the forces of surface tension and gravity as the tape advances, and thermally control the longitudinal change in viscosity of the tape. glass that advances in relation to the tensile stress, so that when the tape has been forced to adopt the desired width and thickness, the viscosity of the tape is such that it prevents a further change of dimensions in it.
