Definitions
- the present invention relates to a support roll, a sheet glass forming apparatus having the support roll, and a sheet glass forming method using the support roll.
- the float method is widely used as a method for forming sheet glass.
- the float method is a method in which molten glass introduced on a molten metal (for example, molten tin) accommodated in a bathtub is caused to flow in a predetermined direction to form a strip-shaped molten glass ribbon. After the molten glass ribbon is cooled in the process of flowing in the horizontal direction, it is pulled up from the molten metal by a lift-out roll, and is gradually cooled in a slow cooling furnace to form a sheet glass. The plate glass is unloaded from the slow cooling furnace, and then cut into a predetermined size and shape by a cutting machine to become a plate glass as a product.
