Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a glass roll manufacturing method for recovering filamentous separation without damaging a glass film.SOLUTION: A glass roll manufacturing method comprises: a transportation step of transporting a glass film G along the longitudinal direction thereof; a cutting step of irradiating the glass film G with a laser beam L from a laser irradiation device 19 thereby to separate the glass film G into a non-product part Gc and a product part Gd; and a winding step of winding the product part Gd in a roll state thereby to constitute a glass roll R. At the cutting step, a filamentous separation part Ge produced from the width direction end portion of the product part is recovered by winding the same on a rod-like recovery member 20a.SELECTED DRAWING: Figure 3 【課題】ガラスフィルムを損傷させることなく糸状剥離物を回収する。【解決手段】ガラスロールの製造方法は、ガラスフィルムＧをその長手方向に沿って搬送する搬送工程と、搬送工程によりガラスフィルムＧを搬送しつつ、ガラスフィルムＧにレーザ照射装置１９からレーザ光Ｌを照射することにより、ガラスフィルムＧを非製品部Ｇｃと製品部Ｇｄとに分離する切断工程と、製品部Ｇｄをロール状に巻き取ってガラスロールＲを構成する巻取工程とを備える。切断工程では、製品部Ｇｄの幅方向端部から生じる糸状剥離物Ｇｅを棒状の回収部材２０ａに巻き付けることにより回収する。【選択図】図３
