When the sub separator paper is used, the sub separator paper is mounted on the separator paper bed in a state of being superposed on the main separator paper. When the electrode plate and the separator paper are mounted on each bed, the movable bed connected to the driving means, for example, the separator paper bed is tilted, and is displaced in the direction close to the fixed bed, for example, the electrode plate bed, Both beds are crossed while maintaining a predetermined angle. Here, when the two beds intersect, a substantially middle portion in the longitudinal direction of the separator paper is located at the position of the winding body forming portion formed on the fixed bed side, and this portion is sandwiched by the winding shaft. Moreover, the respective electrode plates of the anode and the cathode are placed at positions sandwiching this winding shaft. Therefore, by rotating the winding shaft to wind the separator paper and sending the bipolar plates in the winding axial direction, the bipolar plates are wound in a wound state to form a wound body. ..

With this structure, the positive electrode plate and the negative electrode plate are mounted on the electrode plate bed at the same time with a predetermined space therebetween, and the separator paper is a separator provided separately from the electrode plate bed. Since it is mounted on the paper bed, the separator paper and the electrode plate can be mounted on each bed at the same time. Therefore, the member forming the wound body composed of the anode plate, the cathode plate and the separator paper can be arranged and positioned at a predetermined position efficiently at an extremely high speed.
Further, since the anode plate and the cathode plate can be simultaneously mounted on the electrode plate bed by a single mechanism, the structure of the mechanism and means for transferring the electrode plate can be simplified.
