Laminated glass is grooved on both sides, bent first to one and then to the other side, and during the second bending process, the two parts of the laminated glass are pulled apart. The thus stretched film is melted by a plasma jet directed in the gap formed by the bending process, which is moved over the entire length of the gap. The apparatus to perform the process comprises two platelike supports (1, 2) for laminated glass (10) to be cut, of which at least one can swivel back and forth around an axis (4) running in impact area (3) between two supports (1, 2), and with clamping apparatuss to immobilize the laminated glass on the supports. On their lower edges, supports (1, 2) have conveying elements (5, 6) for laminated glass (10) and clamping apparatus (13, 14) to immobilize laminated glass (10). Further, a plasma torch (15) is provided, which has an outlet (30) for the plasma jet directed to impact area (3) between supports (1, 2), and the plasma torch is guided on a guide rail oriented parallel to the axis.
In an apparatus to cut laminated glass, comprising two platelike supports for a laminated glass sheet to be cut, of which one can swivel around an axis running in an impact area between said two supports, and structure to immobilize a laminated glass sheet on said supports, which are placed on both sides of said impact area between said two supports;
In an apparatus to cut laminated glass, comprising two platelike supports for laminated glass to be cut, of which at least one can swivel back and forth around an axis running in an impact area between the two supports, and apparatus to immobilize laminated glass on said supports;
