  • Patent number: 11180405
    Abstract: 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.
    Type: Grant
    Filed: March 10, 2020
    Date of Patent: November 23, 2021

  • Publication number: 20170305240
    Abstract: A laminated glass includes a first glass plate, which varies in a thickness from one end to another end that is opposite the one end, and in which a line is formed; a second glass plate in which a line is formed; and an intermediate film located between the first glass plate and the second glass plate, and configured to bond the first glass plate and the second glass plate so that the line of the first glass plate and the line of the second glass plate are mutually orthogonal, in a view of a plate thickness direction.
