摘要

Production of a stretching plate made from glass comprises removing the plate along a separating line from a glass substrate having a thickness corresponding to the thickness of the plate, through stresses thermally induced into the substrate. Preferred Features: The thermally induced stresses are produced using an energy input directed onto the glass substrate. The energy source is light from a heating lamp, laser beam, a heating wire and/or a hot air blower.
