Abstract
In casting tubular-plate grids, a molten lead alloy is poured into a mold along the long side of the grid perpendicular to the grid rods. Temporary connectors joining adjacent grid rods are simultaneously cast. These connecting portions have a thickened cross-section in the middle and a constricted cross-section at their points of junction with the grid rods. In a subsequent operation, the connecting portions are punched out.
