ABSTRACT:
The invention provides a method for making a thin strap in a stable molten state in producing a plate group for a lead acid storage battery by integrally welding lugs of a plurality of plates of the same polarity by cast-on-strap process. According to the method, the strap is formed in the following manner. A molten lead is fed in a strap forming tool surrounded by an induction heating coil; control of the temperature of the molten lead and preheating of the tips of the plate lugs are carried out by the induction heating coil; the tips of the lugs is dipped in the molten lead and kept at a given temperature; and, thereafter, the mold is forcedly cooled to solidify the molten lead.
