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.

Independent Claims | See all claims (28)

  1. 1. A method of manufacturing glass plates of any contour from flat glasses involving the following steps: 1.1. scribing separation lines (26, 110, 106, 107) of a depth Tglass substrate along the contour in at least one side of the flat glass (1) using a cutting device, 1.2 positioning the glass plate (1) on a base pad (200), wherein 1.3 the base pad has a predetermined hardness, 1.4 a defined force F is applied to the flat glass (1) by means of a pressing facility so that a scribed line is created along the separation lines (26, 110, 106, 107) and 1.5 the hardness of the base pad correlates to the force to be applied, 1.6 the application of the defined force 1.7 causing the scribed line to be driven through the entire thickness of the flat glass (1), 1.8 the defined force to be applied and the hardness of the base pad being chosen such that, when the scribed line is driven through the entire thickness of the flat glass (1), the border of the glass plate is largely prevented from breaking off under transverse stresses.
  2. 23. A device for breaking glass plates of any contour from a flat glass with 23.1 a base pad (200) wherein 23.2 the device has a positioning device for positioning the flat glass to be broken onto the base pad (200) and means for applying a predetermined force and 23.3 the hardness of the base pad is correlated to the force to be applied to drive the scribed line through the flat glass plate and the hardness of the base pad is selected depending on the predetermined force in such a manner that, when the scribed line is driven through the glass, the border of the glass plate is largely prevented from breaking off under transverse stresses..
