  • GLASS PLATE PRODUCTION METHOD AND PRODUCTION DEVICE
    Publication number: 20120144864
    Abstract: The present invention relates to a method for manufacturing a glass sheet, including: running down molten glass along both side surfaces of a molded body; joining and integrating the molten glass just under a lower edge part of the molded body; and pinching and downward delivering an end in a width direction of an integrated sheet-shaped glass ribbon by a roller pair, thereby drawing downward the glass ribbon and molding a center in the width direction of the glass ribbon to have an average thickness of 0.3 mm or less in which a pinching force is adjusted in a desired range.
