Title
(EN) LASER CUTTING OF GLASS ALONG A PREDETERMINED LINE
(FR) DÉCOUPE AU LASER DE VERRE LE LONG D'UNE LIGNE PRÉDÉTERMINÉE
Abstract
(EN) Disclosed are systems and methods for separating a glass sheet along a predetermined line. Laser beams are generated and shaped into elongated laser beams. Arm members are provided that are pivotally coupled together to form a chain of arm members. Each elongated laser beam is directed therefrom a respective laser beam toward the glass sheet to form a contiguous chain of elongated laser beams thereon a surface of the glass sheet. The arm members can be moved to move the contiguous chain of elongated laser beams along the predetermined line to scoring the glass sheet along the predetermined line.
(FR) L'invention concerne des systèmes et des procédés permettant de séparer une feuille de verre le long d'une ligne prédéterminée. Des faisceaux laser sont produits et modelés sous la forme de faisceaux laser allongés. Des bras sont accouplés pivotant les uns aux autres de façon à former une chaîne de bras. Chaque faisceau laser allongé est dirigé d'un faisceau laser respectif vers la feuille de verre de façon à former une chaîne continue de faisceaux laser allongés sur une surface de la feuille de verre. Les bras peuvent être déplacés de sorte que la chaîne continue de faisceaux laser allongés soit déplacée le long de la ligne prédéterminée afin d'entailler la feuille de verre le long de cette ligne.
