  • Formed glass sheet having controlled edge stresses
    Patent number: 6015619
    Abstract: A cooling ring assembly (20) and method for controlling stresses in a bent glass sheet G produce a strengthened bent glass sheet after the cooling is completed. The cooling ring assembly includes a cooling ring (22) that supports the glass sheet edge (24), an insulator (30) juxtaposed inboard of the cooling ring to reduce the cooling rate, and a cooler (34) for providing increased cooling to at least one localized area (36,40,58) of the glass sheet edge. The cooler (34) is preferably embodied by a pressurized air supply (42).
    Type: Grant
    Filed: August 24, 1998
    Date of Patent: January 18, 2000
    Assignee: Glasstech, Inc.
    Inventors: James P. Schnabel, Jr., Donivan M. Shetterly, Robert E. Malby, Jr.

The cooling ring assembly includes a cooling ring (22) that supports the glass sheet edge (24), an insulator (30) juxtaposed inboard of the cooling ring to reduce the cooling rate, and a cooler (34) for providing increased cooling by pressurized air to at least one localized area (36,40,58) of the glass sheet edge. The cooler (34) is preferably embodied by a pressurized air supply (42).
