Abstract
Processes and methods for preparing glass panels for use with automobiles include mixing and melting glass particles. Molten glass is passed along into a lehr, where the molten glass is annealed. Annealed glass is cut into glass panels. A nozzle systems delivers compressed air to the glass panels to form a curvature for providing a top seal contact area. A nozzle system delivers a second blast of compressed air, which marks the glass panel to identify characteristics of the glass panel.
