Beschreibung
Zusammenfassung:	A method of making a glass article having non-flat portions, said method comprising the steps of (i) perforating a glass blank along a contour with a laser and forming multiple perforations in the glass blank; (ii) bending the glass bank along at least one area containing perforations, such that the glass is curved, forming a glass article having the non-flat portion. Cette invention concerne un procédé de production d'un article en verre comportant des parties non plates, ledit procédé comprenant les étapes de (i) perforation d'une ébauche en verre suivant un contour à l'aide d'un laser et formation de multiples perforations dans l'ébauche en verre; (b) cintrage de l'ébauche en verre au moins le long d'une zone contenant des perforations, de façon que le verre soit incurvé, pour former ainsi un article en verre comportant une partie non plate.
