Glass roll manufacturing method

The method for manufacturing a glass roll includes: a supply step of supplying a glass film; a cutting step for cutting the glass film by irradiating the glass film with laser light from the laser irradiation device; a winding step in which the glass film after the cutting step is wound into a roll by a winding device; and a downstream-side adjustment step for adjusting the position of the glass film after the cutting step by means of a downstream-side adjustment device provided between the laser irradiation device and the winding device. 玻璃卷的制造方法包括：供给工序，供给玻璃膜；切断工序，通过从激光照射装置向玻璃膜照射激光，从而将玻璃膜切断；卷绕工序，利用卷绕装置将切断工序后的玻璃膜呈卷状卷绕；以及下游侧调整工序，利用设置于激光照射装置与卷绕装置之间的下游侧调整装置来调整切断工序后的玻璃膜的位置。
