Document Type and Number:
WIPO Patent Application WO/2023/223903
Kind Code:
A1
Abstract:
A film roll holding device (1) comprises: a measurement part (40) that generates measurement data by measuring a side surface of a film roll (80) held by a holding part (30); an analysis part (11) that generates an indication value related to a void between film layers by analyzing the measurement data; and a prevention control part (13) that determines whether a temporal change in the indication value has exceeded a threshold, and that, upon determining that the temporal change has exceeded the threshold, rotates the film roll (80) by a predetermined amount by means of a rotation mechanism (313).
