Title:
ROLL BODY MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/149415
Kind Code:
A1
Abstract:
Provided is a roll body manufacturing method comprising: a processing step PY in which a strip-like glass film 1 is subjected to manufacturing-related processing while being passed through a processing section S, which is provided on a conveyance path for the strip-like glass film 1; and a winding step P6 in which the processed glass film (glass film sheet 1x) that has passed through the processing section S is overlaid onto a strip-like protective sheet 3 and then wound around a core 4, so as to produce a roll body 5. In this method, the manufacturing-related processing entails performing processing to cut out the glass film sheet 1x from the strip-like glass film 1, and in the course of this processing, a winding speed V7 at which the glass film sheet 1x is wound around the core 4 is accelerated compared to a feeding speed V5 at which the strip-like glass film 1 is fed into the processing section S.
