  • Publication number: 20070000285
    Abstract: 5 An apparatus and method for bending glass substrate(s) are provided. Microwave radiation is used to heat glass substrate(s) for bending. As a result, a coating supported by the substrate(s) is not heated as much during the bending process compared to if only conventional IR radiation was used. Thus, more extreme degrees of glass bending may be achieved, and/or the likelihood of coating damage reduced.

  • Patent number: 6598426
    Abstract: A method of making a vehicle windshield or other window. An opaque layer (e.g., enamel or water-based) is applied to a glass sheet and then “fired” or cured. The opaque layer is preferably black or dark in color. Thereafter, the sheet with the opaque layer thereon is cut into a desired windshield shape, along a cutting line which extends through both the glass sheet and the opaque layer formed thereon. As a result, on the cut glass sheet the opaque layer extends all the way up to the peripheral edge thereof. In vehicle windshield embodiments, the cut sheet is laminated to another glass sheet via at least a polymer based interlayer in order to form the vehicle windshield.
