Title:
ROLL PRESS DEVICE, AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/140747
Kind Code:
A1
Abstract:
In this roll press device, a secondary battery electrode plate being continuously conveyed is rolled by being sandwiched between a first pressing roller and a second pressing roller. The control unit controls the loads of each of a first compressing mechanism, a second compressing mechanism, a first bending mechanism, and a second bending mechanism on the basis of setting values calculated by a calculating unit. The calculating unit changes the setting values of the first compressing mechanism and the second compressing mechanism in advance in such a way as to reduce variations in the thickness of the electrode plate corresponding to variations in the speed of an electrode plate conveying line.
