摘要

Production of a binder plate made from glass having at least one side edge with two edge lines comprises mechanically scribing and breaking along the scribed line. The side edge lying opposite the scribed line is thermally or chemically rounded. Preferred Features: The side edge obtained by the breaking of the binder plate is hardened to increase the resistance.
