A number of strap-forming metal molds 12 corresponding to the number of steps are arranged on a circumferential track and are fed to the devices of the respective steps A.about.F together with electrode plate groups 10. Position A is an electrode plate group 10 introduction position; position B is a flux coating position in which electrode plate leads 6 are coated with flux; position C is an auxiliary heating position in which a mold 8 is heated to the temperature of the molten lead; position D is a molten lead pouring position in which molten lead is poured into a mold 8; position E is a strap-forming position in which electrode plate leads 6 are inserted into the molten lead, fused and cooled and the molten lead is solidified; position F is a discharge position in which a completed electrode plate assembly is discharged. Heating of a mold 8 is commenced by inductive heating from position F and is continued to position E.
A device for manufacturing an electrode plate assembly for a lead accumulator wherein an electrode plate group is formed by alternately stacking, with interposition of separators, a plurality of electrode plates of both positive and negative electrodes, a positive electrode row and negative electrode row respectively of electrode plate leads formed in projecting manner on each electrode plate being inserted in molten lead that is poured into a mold of strap shape, so that the electrode plate leads are fused with the molten lead, an electrode plate assembly then being manufactured by unitarily linking and joining the rows of electrode plate leads of respective positive and negative electrodes by means of a strap formed by the molten lead solidified by cooling the mold, comprising:
