ABSTRACT:
This invention relates to a method of making a storage battery plate grid comprising the steps of casting a series of grids between the continuous cylindrical patterned end surface of a rotating drum and a smooth surfaced co-operating shoe, cropping said series of grids, said rotating drum being patterned to form said grids with one smooth side, with a perimeter frame, with a lattice network within said frame and with said perimeter frame of a greater thickness than said lattice network; flattening said grids supporting the grids and displacing the lattice network portion of said grid to dispose the principal plane of the lattice network portion thereof between the spaced apart planes of the opposed faces of said perimeter frame.
