  • 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.

  • Patent number: 6870129
    Abstract: The cutting of the flat glass plate (1) into rectangular plates with a predetermined edge length is performed by forming initial cracks at the beginning of cutting lines on the glass plate and moving a laser beam along the cutting lines followed by a cooling spot to induce a thermo-mechanical stress alone the cutting lines. First the glass plate (1) is cut apart into partial plates (2-5) along first parallel cutting lines spaced according to the predetermined edge length. Then the cut apart glass plate is rotated by 90° and the partial plates (2-5) are moved apart from each other. Subsequently the partial plates that have been moved apart are cut apart alone several parallel second cuts (4-9) perpendicular to the first cuts. This method facilitates exact placement of the initial cracks.

  • Publication number: 20040020960
    Abstract: The cutting of these rectangular plates with predetermined edge lengths is typically effected by means of a laser, which is displaced along the cutting lines, in conjunction with a trailing cooling spot for inducing a thermomechanical stress that is greater than the breaking strength of the glass, and by means of a mechanically induced initial crack at the beginning of the cutting line. When the flat glass plate (1) is in an initial position, a number of parallel first cutting lines (1-3) are made. Afterwards, the flat glass plate (1) that is cut up in such a manner is rotated 90°, and the partial plates (2-5) are moved apart by virtue of the fact that a displaceable table segment of a cutting table is assigned to each partial plate. In this position, several parallel second cuts (4-9) are then made that are perpendicular to the first cuts, whereby, on each partial plate, an initial crack is induced on the leading edge.

  • Publication number: 20030145624
    Abstract: The invention relates to a method for producing glass panes 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 glass pane?, using a cutting device, and positioning the glass pane 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.
