Abstract: Method and machine for manufacturing grids from lead-based metal for use in storage batteries of the type wherein a casting is first performed of grid blanks the periphery of which is irregular and the size greater than that of the grid to be obtained, these blanks being thereafter cut out in an automatic press. In view to increase the rate of output of the press and to improve the quality of the grids, the press is supplied sequentially from a continuous grid-blank feeding conveyor and at least one final lateral centering of the grid blank is performed in the press by the combined action of two pusher members tapping on each side of the grid blank in a transverse direction passing substantially from the center of mass of the grid blank.
