Title: METHOD AND APPARATUS FOR BENDING THIN GLASS
Abstract:
The present invention provides for a method and apparatus for bending multiple sheet of thin glass at the same time on a single set of molds. Multiple sheets of thin glass are stacked onto a full surface female mold. A partial surface male mold is placed onto the thin glass stack. The male mold serves to hold the edges in place and prevents the formation of wrinkles as the glass is heated and sags to conform to the shape of the female mold. Optionally, the top mold can be enclosed and pressurized to provide a pneumatic pressure assist to form the glass. In addition, the bottom mold can be enclosed to allow for vacuum assist to form the glass.
