<p>PURPOSE:To provide a device for efficiently manufacturing a spiral plate group of high reliability for a cylindrical sealed nickel-cadmium storage battery in which there is no positional divergence between a separator and a positive and a negative plate. CONSTITUTION:Positions (A)-(F) are located in the periphery of a dividing rotary board 22 at equal intervals. At the position (A) when a winding jig is installed, a belt- like negative cadmium plate 1 is supplied to a wound core area through the guide hole of a separator supplying part 18 and a positive nickel plate 4 is supplied to the wound core area through the fixed guide of the rotary board 22 after a wound core 8 is rotated by 360 deg.C, thereby completing rolling of the plates 1 and 4 and a separator into spiral form at a preset rotational frequency. In the next process (B), a part of the separator located at the end of the rolled plate group is cut with a nichrome wire heater 21. In the following process (C), a bar-like plunger 28 is moved upward in a sleeve 27 having a tapered section at its upper end thereby laterally folding the lead piece 6 of the negative cadmium electrode securely. After that, the plate group is pushed into a battery case prepared under the rotary board 22 through a guide jig at the position (D) before the battery case is fed outside from the rotary board 22 at the position (E).</p> |
