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.

Abstract: An intermittent valve device includes: an intermittent valve capable of switching between a first state in which a coating material is supplied to a die that applies the coating material onto a material to be coated and a second state in which the supply of the coating material is stopped; and a drive unit that switches the first state and the second state of the intermittent valve. The drive unit includes a cam that rotates in one direction with a circumferential surface of the cam connected to the intermittent valve. The cam includes, on the circumferential surface, a first shape part that places the intermittent valve in the first state, and a second shape part that places the intermittent valve in the second state.

Abstract: An intermittent coating device includes a die used to apply a coating material onto a material to be coated, and a first intermittent valve and a second intermittent valve capable of switching between a first state in which the coating material is supplied to the die and a second state in which the supply of the coating material is stopped. The first intermittent valve and the second intermittent valve have different timings of switching between the first state and the second state.
