Document Type and Number:
WIPO Patent Application WO/2018/116751
Kind Code:
A1
Abstract:
In this plate glass manufacturing method, in a step for cutting a belt-like sheet base material 19a, the remaining length to the cut position from the position of the joint between a first belt-like sheet base material 19a and a second belt-like sheet base material 19c detected by a sensor 33 in a detection step is calculated. From the first belt-like sheet base material 19a, a sheet member S of a prescribed length is cut while calculating said remaining length. If the remaining length becomes shorter than a prescribed length, then the portion after the joint of the second belt-like sheet base material 19b is cut to form a disposable sheet material Sa that contains the joint.
