Abstract
In a roll press device, a thickness meter is provided on the exit side of first and second pressure rollers and detects the thickness of an electrode plate of a secondary battery at three or more points in the width direction of the electrode plate. From thickness measurement values at the three or more points and a thickness target value, a calculation unit calculates three feature amounts: the deviation between a thickness measurement value at the central point among the three or more points and the thickness target value, the quadratic component of the thickness profile of the electrode plate, and the linear component of the thickness profile of the electrode plate, and adaptively changes the respective pressure setting values of the first press mechanism, the second press mechanism, the first bend mechanism, and the second bend mechanism based on the three feature amounts.
