- the invention relates to furthermore a device with which the method is carried out with the features of the introductory part of claim 16.
- Glass panels are cut to the desired size by scratching and breaking Cut to size, which is usually on so-called “glass cutting tables” and these "break tables” assigned to them.
- the glass panes obtained in this way have very sharp-edged, Burr edges, what for subsequent handling of the glass panes, for example when producing insulating glass panes is disadvantageous.
- On the one hand there is a risk that the edges of the glass panes break out and on the other there is a not inconsiderable risk that someone will turn to the sharp edges of the glass panes injured by cutting.
- Those attacking at the edges of the glass panes are also subject Support and means of transport (e.g. conveyor rollers or Conveyor belts) through unprocessed edges of glass panes heavy wear.
- the invention has for its object a method and a device for trimming the edges of glass panes To provide with which glass panes are processed in this way that their edges are no longer sharp, in particular have no burrs.
- the method according to the invention can be done in different ways be carried out. So it is possible, for example, one after the other trimming all (four) edges of a glass pane on both sides, why the glass pane after trimming the edges of an edge, for example around a perpendicular to its plane Axis, is rotated until the next edge of the glass pane, the edges of which are to be trimmed in the processing position located.
