METHOD FOR LASER CUTTING BENT GLASS FOR SHAPE AND OPTICS MATCH

Abstract:

Embodiments of the disclosure relate to a method of preparing a multi-piece laminated article. In the method a first glass ply and a second glass ply are co-sagged. The first glass ply is laser cut to form a first primary piece and a first secondary piece, and the second glass ply is laser cut to form a second primary piece and a second secondary piece. The first primary piece and the second primary piece each define a hole into which the first secondary piece and the second secondary piece, respectively, fit. The first primary piece and the second primary piece are laminated to each other to form a first laminated piece, and the first secondary piece and the second secondary piece are laminated to each other to form a second laminated piece. The method can be used to prepare, for example, automotive glazing.
