A method for scoring flat glass sheet includes moving an optical assembly, which is adapted to direct electromagnetic radiation from a radiation source. The method also includes impinging the electromagnetic radiation on a glass sheet, forming an elongated heating zone on the sheet, wherein a distance from the radiation source to the glass sheet is substantially constant during the moving. An apparatus is also described. L'invention concerne un procédé de rainurage d'un panneau de verre plat consistant à déplacer un ensemble optique conçu pour émettre un rayonnement électromagnétique à partir d'une source de rayonnement. Le procédé consiste également à appliquer un rayonnement électromagnétique à un panneau de verre et à former une zone de chauffage allongée sur le panneau, une distance entre la source de rayonnement et le panneau de verre étant essentiellement constante lors du déplacement. L'invention concerne également un dispositif destiné à la mise en oeuvre de ce procédé.
