Title (EN) METHOD AND DEVICE FOR CUTTING HOLLOW GLASS ARTICLES BY A LASER BEAM
(FR) PROCEDE ET DISPOSITIF POUR COUPER DES ARTICLES CREUX EN VERRE AVEC UN FAISCEAU LASER
Abstract: front page image
(EN)A method and device for cutting hollow glass articles (1) by laser, comprising a first stage in which an incision is made along the circumferential cutting line in the articles, which are rotating about their axis. The article is rotated about its axis. The incision is made by a focused laser beam (3). The article, simultaneously with the incision, is blasted in correpondence with the irradiated point by a pressurized jet of a fluid for cooling and cleaning the incision channel.
(FR)Procédé et dispositif pour couper des articles creux en verre (1) avec un laser, comportant une première étape pendant laquelle un incision est pratiquée sur la ligne de coupure autour des articles, ces derniers tournant autour de leur axe. L'incision est réalisée à l'aide d'un faisceau laser focalisé (3). Simultanément à cette incision, un jet de fluide pressurisé est soufflé sur le point irradié de l'article pour refroidir et nettoyer le canal d'incision.
