ABSTRACT:
Method of connecting a battery plate to a battery strap or post in a mould 50 provided with a number of separate mould cavities 51 arranged on each side of a duct or channel 52 for receiving molten lead. Between each mould cavity 51 and the channel 52 is positioned a weir or barrier 60 which determines the level of lead in each cavity. Lead pumped into the channel 52 flows into the cavities 51 over the weirs 60, the level of lead in channel 52 then drops below the top of the weirs 60 so that the level of lead in the cavities 51 falls to the level of the top of the weirs 60. The lugs 22 of battery plates 23 are then dipped into the lead in the cavities and the lead solidifies to form finished straps or posts. During the moulding process the lead is maintained in a molten state using heaters 78 and the mould cavities are cooled with a flow of cooling water.
