Abstract:
1. A method for manufacturing glass plates of any contour from flat glasses comprising the following steps: scribing a separation line of a depth T along the contour in at least one side of the flat glass using a cutting device, the separation line along the contour defining a closed area circumscribed thereby, positioning the flat glass on a base pad, wherein the base pad has an aperture being larger in size than the contour defined by said separation line, said aperture extending continuously beneath the entire area defined by said scribed contour, and wherein the flat glass is sandwiched between two flexible plates prior to being placed on the base pad, wherein a force F is applied to the flat glass on the side opposite said aperture using a punch with a punch area smaller than the base pad aperture so that a break is created along the separation line, the break being driven through the entire thickness of the flat glass.
