<p>A method for cutting the edges of a continuous glass ribbon (10), moving at a speed VR, comprising a longitudinal marking stage which generates a marking line, in particular using a cutting wheel (11), a transverse marking stage, and a subsequent transverse breaking stage. The inventive method also comprises an intermediary stage between the longitudinal marking stage and the transverse marking stage consisting in generating at least one longitudinal fissure (32) through at least a substantial part of the thickness of the continuous glass ribbon, or through the entire thickness of the continuous glass ribbon, on the basis of the marking line (30), and in spreading said longitudinal fissure at a speed VF, which is more or less equal to but in the opposite direction to the speed VR of the moving continuous glass ribbon. The invention also relates to a device designed to carry out said method. The glass plates cut using the inventive method have edges, advantageously, without any major defects.</p> |
