Abstract: First chucks feed material sheets of glass to a heating device and a drawing device. Third chucks hold the first material sheet of glass after it is lowered and the first chucks then release the first material sheet of glass. The first chucks then return to pick up the second material sheet of glass and are then lowered to catch up with the first material sheet of glass. Both material sheets of glass are then heated, softened, fused and bonded. After fusing and bonding, the feed of the second material sheet of glass is continued by the first chucks, which are replaced by the third chucks on the way. Thereafter the same action is repeated for subsequent material sheets of glass, and thin sheet glass is continuously manufactured from the material sheets of glass by a redrawing process.
