Abstract

Method of cutting successive sheets of glass to a desired shape esp. windscreen shapes, comprises (a) raising the sheet, already marked out with the scratched contour of the desired pattern, by means of suction pads and (b) hitting its edges against an elastic stop mounted on a chassis so that the sheet breaks along the scratched contour. The pieces of glass broken off from the sheet are swept away and collected.
