<p>A system for breaking large sheets of brittle material, such as glass, into smaller sheets, in which one laser (16) is moved across a glass sheet (10) having two major surfaces (11) to form two vent cracks (19, 19a) in the glass sheet (10); a first vent crack (19) in a first path on one side of the glass sheet (10), and a second vent crack (19a) in a second path on the other side of sheeet (10). The glass sheet (10) is broken into smaller sheets by applying a bending moment under the vent cracks (19, 19a).</p> |
