Apparatus for braking glass panes scored at only one side

In a device for breaking unilaterally scribed, in particular one-sided with a metal coating provided glass sheets (2), are a crushing bar (7) or a rotationally driven crushing roller (28) which is raised from below against the glass sheet (2), and two from above Her against the glass sheet (2) acting abutment (9 and 10) provided. The abutments (9 and 10) are not physically attached to the top of the glass sheet (2), but held by an air cushion generated between them and the top of the glass sheet (2), which is formed by compressed air flowing out of nozzles (14). low. In this way, friction movements, which could damage the coating (3) of the glass sheet (2) during the breaking process, excluded.
