METHOD AND DEVICE FOR PRODUCING GLASS PANES OF ANY DESIRED CONTOUR FROM SHEET GLASS

To process glass sheets, they are assembled into a stack each with at least one intermediate layer. After the treatment, they are separated by the removal of at least one intermediate layer. The glass sheet processing includes at least the separation of a stack of small glass surfaces, giving circul...

Zusammenfassung:	To process glass sheets, they are assembled into a stack each with at least one intermediate layer. After the treatment, they are separated by the removal of at least one intermediate layer. The glass sheet processing includes at least the separation of a stack of small glass surfaces, giving circular glass surfaces. An additional contour can be cut out of the stack before, during or after the stack separation, to give a stack of small glass surfaces with an inner hole. The contour is cut by drilling, supported by ultrasonics. The separation can also include an edge working stage. The intermediate layer contains glass balls. The intermediate layer can be structured of two water-soluble layers forming a sandwich with a water-insoluble adhesive. The stack of glass sheets and intermediate layers is compressed. At least one intermediate layer is dissolved for removal by washing in warm water. Or the washing separates the glass layers for the intermediate layer to be extracted. The water-insoluble intermediate layer is dissolved for removal.
