<p>A METHOD AND AN APPARATUS FOR CUTTING A LAMINATE (1) MADE OF A BRITTLE MATERIAL (2) AND A PLASTIC (4) IWTH A CUTTING TOOL (5) IS DESCRIBED. THE PLASTIC (4) IS HEATED UP, THEREBY LOWERING ITS VISCOSITY, AT LEAST IN THE REGION OF A PREDETERMINED CUTTING LINE. A CUTTING TOOL (5) IS PLACED ONTO THE PLASTIC (4) SIDE OF THE LAMINATE (1), THE LOADING PRESSURE BEING ADJUSTABLE. BY MOVING CUTTING TOOLS RELATIVE TO THE LAMINATE (1) ALONG THE PREDETERMINED CUTTING LINE, THE PLASTIC (4) IS SEVERED; AT THE SAME TIME THE BRITTLE MATERIAL (2) IS SCORED, THEREBY INDUCING A MECHANICAL STRESS. IF APPROPRIATE, THE MECHANICAL STRESS ALONG THE CUTTING LINE IS SUBSEQUENTLY INCREASED TO EXCEED THE RUPTURE STRENGTH OF THE SCORED BRITTLE MATERIAL (2). A PREFERRED APPLICATION IS THE CUTTING OF THIN GLASS OR GLASS-CERAMIC/PLASTIC LAMINATES.</p> |
