Title (EN) METHOD FOR PRODUCING GLASS FILM
(FR) PROCÉDÉ DE PRODUCTION D'UN FILM DE VERRE
(JA) ガラスフィルムの製造方法
Abstract:
(EN) A transport step in a method for producing a glass film G comprises a wrinkle removal step for removing wrinkles from the glass film G by a wrinkle removal unit 20 disposed on the upstream side from a laser irradiation device 25. A cutting step in the method for producing a glass film G involves separating the glass film G by irradiating the glass film G with laser light L after wrinkles Ge are removed from the glass film G in the transport step, and generating a filamentous peeled product Gg from the width-direction end portion of the separated glass film G.
(FR) La présente invention concerne une étape de transport dans un procédé de production d'un film de verre G comprenant une étape d'élimination des plis permettant d'éliminer les plis du film de verre G grâce à une unité d'élimination de plis (20) disposée du côté amont par rapport à un dispositif d'irradiation laser (25). Une étape de découpe, dans le procédé de production d'un film de verre G, implique la séparation du film de verre G par exposition du film de verre G à une lumière laser L après l'élimination des plis Ge du film de verre G à l'étape de transport, et la génération d'un produit filamenteux pelé Gg à partir de la partie d'extrémité dans le sens de la largeur du film de verre G séparé.
(JA) ガラスフィルムGの製造方法における搬送工程は、レーザ照射装置25よりも上流側に配置される皺除去部20によりガラスフィルムGの皺を取り除く皺除去工程を備える。ガラスフィルムGの製造方法における切断工程は、搬送工程においてガラスフィルムGの皺Geを除去した後に、レーザ光LをガラスフィルムGに照射することによりガラスフィルムGを分離し、分離されたガラスフィルムGの幅方向端部から糸状剥離物Ggを発生させる。
