A method is provided for aligning scoring tools and for scoring glass, in particular thin glass, along predetermined scoring lines in preparation for breaking along the score. Glass substrates, in particular thin glass substrates, produced by such method are also provided. The method includes the determination of the actual orientation of the cutting edge of the scoring tool and aligning of the cutting edge to a target orientation of the cutting edge.

Apparatus and method for aligning scoring needles and for scoring glass substrates

A glass substrate strip is provided includes a large number of thin-glass segments, which have been positioned and fixed on an adherent foil. The thin-glass segments have been fixed on the adherent foil by one of their entire area, their entire edge region, or their edge regions. The glass substrate strip can include lateral transport bands or coding fields. For storage, glass substrate strip is plated in undulating fashion or is rolled up, and it serves not only for transport and storage but also as carrier strip in processing steps for the thin-glass segments.

In the method for coating substrates the substrates are placed in recesses in a glass-ceramic plate or plates arranged over infrared high-temperature radiators with the surfaces to be coated on the radiators. The substrates are heated from below to the process temperature required for the coating. Subsequently the substrates are removed from the heating device, introduced into a coating chamber and coated. The preheating device for the substrates has two glass-ceramic plates that are placed loosely on top of each other and infrared high-temperature radiators. Substrate receptacles are provided in the glass-ceramic plates by approximately coincident recesses of different size in the plates so that the substrates can be held in close proximately to the radiators during the preheating.
