The invention relates to a method for smoothing the edges of a glass pane, wherein ° a. a first laser beam (1a) from a first laser (1) having a wavelength of 6 µm to 12 µm is applied to a pane edge (3) of a glass pane (4), a first local heating region (1b) is produced in the glass pane (4) on the pane edge (3), and the first local heating region (1b) has an area having a width of 0.1 mm to 2 mm and is heated to a temperature above the transition temperature of the glass and causes a melting of the pane edge (3) in the first local heating region (1b) to a depth of 2 mm to 3 mm, ° b. a second laser beam (2a) from a second laser (2) having a wavelength from 0.30 µm to 2.00 µm is applied to the glass pane (4), and a second local heating region (2b) adjacent to the first local heating region (1b) is produced in the glass pane (4) below the pane edge (3), and ° c. the first laser beam (1a) is guided along the pane edge (3), and the second laser beam (2a) is guided parallel to the pane edge (3), wherein the second laser beam (2a) is guided at the same height or behind at a distance of at most 20 mm to 50 mm from the first laser beam (1a). |
