2 is a view showing an apparatus for manufacturing a plate used in the capacitor of the present invention. Referring to FIG. 2, the steel roll plate 2 wound around the coil is flattened and passed through the roller portion 10.

The roller portion 10 is for forming the groove 22 in the longitudinal direction on the flat plate 20. The roller part 10 is provided with the primary rollers 11 and 12, the secondary rollers 13 and 14, and the tertiary rollers 15 and 16 which face each other. Each of the rollers has a convex portion and a concave portion for forming the grooves 22 facing each other. The primary rollers 11 and 12 have a convex portion 11a formed on the upper roller 11 and a lower roller. The recessed part 12a is formed in 12. As shown in FIG. The plate 20 is deformed under pressure between the convex portion 11a and the concave portion 12a to form the groove 22.

In order to form a plurality of grooves 22, a plurality of convex portions and concave portions must be formed in a pair of rollers, but in this case, since the deformation is uneven, the secondary rollers 13 and 14 and the tertiary rollers 15 and 16 ), It is preferable to provide only a suitable convex portion and a concave portion in the pair of rollers. If the primary rollers 11 and 12 are for forming the groove 22 at the center side, the secondary rollers 13 and 14 have convex portions 13a and concave portions 14a on the outer side and the outer grooves. (22) can be formed. As the number of grooves 22 increases, the number of rollers increases.

The plate 20 in which the groove 22 is formed is cut to a predetermined length by the press action of the cutting machine 30. The controller (not shown) controls the operation of the cutting machine 30 by measuring and calculating the rotation speed and the speed of the roller unit 10. The plate 20, which has undergone such a rolling step and a cutting step, is integrated with the pipe through the following combination step.

The shape of the roller is shown in detail in (b), (c) and (d).
