が採用されていた。Prior Art A conventional spiral spiral pole body is manufactured by winding a separator 1, an anode plate 2, and a cathode plate 3 in a spiral shape as shown in the second quotient. The separator 1 interposed between the plate 3 and the separator 1 was one layer. However, since the electrode plate is harder and more difficult to bend than separator 1, the moment the tip of the electrode plate gets caught up in the separator, the tip of the electrode plate damages separator 1 and the plates come into contact with each other, causing a short circuit. ? It had the disadvantage that it was easy to cause problems. Conventionally, to solve this problem, 113
As shown in the figure, there is a method in which a pair of separators 1 are prepared and a part of them is welded using the rx welding jig 5 to form a double structure. Then, a pair of separators 1yIll-overlap (1:, as shown in 4)
By sandwiching it with the clamping tool 6 to create a double structure,
A method has been adopted to prevent short circuits due to damage to the separator 1.

有していた。Problems to be Solved by the Invention In the welding method described above, the separator 1 may be melted during welding, or the residue of the melted separator 1 may adhere to the welding jig 5. If it adheres to the welding jig 5, it will be at a high temperature (which has disadvantages such as poor operability), and the method of holding the separator 1 with the clamping tools 6 has disadvantages such as misalignment of the separator 1.
