ABSTRACT:
The method relates to breaking glass sheets (5) with a line scored on one side, the glass sheet (5) being first raised at one end of the scored line and thereupon, in the remaining areas, it is progressively raised beginning with the initially lifted end. To carry out this breaking method, a breaking table (1) is provided of which the lifting strip (7) or roller can be raised on one side (I) first and then gradually lifted into the position II parallel to the table support surface (4). The glass sheet (5) is depressed on both sides of the lifting strip (7) or roller by suction heads (20) under partial vacuum or by boreholes (13) communicating with a source of partial vacuum.
