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.
Claims17
A method of making a vehicle windshield, the method comprising:
- providing a first glass sheet;
- applying an opaque layer on the first glass sheet;
- firing or curing the opaque layer on the first glass sheet using microwave energy;
- after the firing or curing of the opaque layer on the first glass sheet, cutting the first glass sheet along a cutting line into a desired peripheral shape, wherein the cutting along the cutting line extends through both the first glass sheet and the fired or cured opaque layer thereon so that after said cutting the opaque layer extends all the way to a peripheral edge of the cut first glass sheet;
- and
- laminating the cut first glass sheet to a second glass sheet in order to form the vehicle windshield.
A method of making a window, the method comprising:
- providing a first glass sheet;
- applying a dark colored or black opaque layer on the first glass sheet;
- firing or curing the dark colored or black opaque layer on the first glass sheet;
- and
- after the firing or curing of the dark colored or black opaque layer on the first glass sheet, cutting the first glass sheet along a cutting line into a desired peripheral shape, wherein the cutting along the cutting line extends through both the first glass sheet and the fired or cured opaque layer thereon so that after said cutting the opaque layer extends all the way to a peripheral edge of the cut first glass sheet.
