  • Patent number: 7699199
    Abstract: A method for producing glass plates of any desired contour from sheet glass, comprising the following steps: scribing scribe lines into a least one face of the sheet glass along the contour down to a depth, using a cutting device, and positioning the glass plate on a support. The method is further characterized in that a defined force F is applied to the sheet glass so that it breaks along the scribe lines, said break extending through the entire thickness of the sheet glass. The flat glass may be sandwiched between two flexible plates prior to being placed on a base pad and being subjected to the breaking force.

  • Patent number: 7104431
    Abstract: A method for producing glass plates of any desired contour from sheet glass, comprising the following steps: scribing scribe lines into a least one face of the sheet glass along the contour down to a depth T, using a cutting device, and positioning the glass plate on a support. The inventive method is further characterized in that a defined force F is applied to the sheet glass so that it breaks along the scribe lines, said break extending through the entire thickness of the sheet glass. The flat glass may be sandwiched between two flexible plates prior to being placed on a base pad and being subjected to the breaking force.
