Glass plate manufacturing method, a glass plate and a method for cooling the glass plate manufacturing equipment

摘要

Was allowed to flow down along both sides formed body (10), molten glass overflowing from the molded body (90), a glass plate production apparatus of the present invention, a glass plate to be joined at the vicinity of the lower end portion of the molded article an adjustable glass sheet manufacturing apparatus for manufacturing a (91), the cooling rate of the glass plate, and a cooling adjustment plate, a plurality of temperature control unit. Beneath the joining point of the molten glass, is disposed in parallel along the flow direction of the molten glass, cooling adjustment plates The plurality of adjusting the cooling rate of the glass plate. And provided corresponding to each cooling plate adjustment, temperature control unit controls the temperature of the cooling adjustment plate.
