  • Method and apparatus for forcedly cooling sheet glass and tempered sheet glass
    Publication number: 20040107733
    Abstract: A method for forcedly cooling sheet glass includes the step of causing water-cotaining members (11,31) to contact with both surfaces of sheet glass (27) to cool the sheet glass. Sheet glass heated to a predetermined temperrature is brought into contact with water-containing members to thereby quench the surface of the sheet glass. Water in the water-containing members partly evaporates owing to the heat of the sheet glass, and the sheet glass is thereby effectively cooled by the heat of evaporation of water.
