VERFAHREN UND VORRICHTUNG ZUM ZERBRECHEN VON SPRÖDEM MATERIAL

摘要

A system for breaking large sheets of brittle material such as glass into smaller sheets, in which at least one laser is moved across a sheet of brittle material having two major surfaces to form two vent cracks in the sheet, a first vent crack in a first path on one side of the sheet and a second vent crack in a second path on the other side of the sheet. The sheet is broken into smaller sheets by applying a bending moment under the vent cracks.
