Abstract

PURPOSE:To increase workability in production and prevent short circuit by bonding the lapped part of a pair of separators by supersonic wave, applying press rollers to facing winding axces, inserting a cathide plate and an anode plate into between winding axes and a separator, and rotating them. CONSTITUTION:Lapped separators 1 are fed and a separator 1 located on a supersonic wave generating tool 8 side is cut in a given size with a cutter 9, and the lapped part of the separator 1 is welded with the supersonic wave generating tool 8. Semicircularly divided winding axes 4 are placed from a facing direction, and the separator 1 on a guide 10 side is cut in a given size with a cutter 9. Press rollers 7 are applied to the winding axes 4 from a facing direction, and a cathode plate 2 and an anode plate 3 are inserted into between the lapped separators 1, and th winding axes 4 are rotated to spirally winding them. By this process, the separator is bonded in a short time, and short circuit caused by damage of the separator is prevented.

る方法が採用されていた。Prior Art A conventional spiral electrode body is manufactured by winding up a separator 1, an anode plate 2, and a cathode plate 3 in a spiral shape around a winding shaft 4, as shown in Figure @2. However, since the seed plate is harder and more difficult to bend than the separator 1, the tip of the electrode plate has the disadvantage that it is easy to cause separation failure. In order to solve this problem, as shown in Fig. 3, a pair of separators 1
There is a method in which a pair of separators 1 are overlapped and welded using a welding jig 5 to form a double structure, or as shown in FIG. ), a method has been adopted in which short circuits due to damage to the separator 1 are prevented by sandwiching the separator 1 with a clamping tool 6 to form a double structure.
