ABSTRACT:
An apparatus and method for automatically removing flash from a plastic weld bead formed around the outer periphery of a heat seal juncture between a plastic cover and container of a lead-acid battery cell. The container and cover are automatically positioned with respect to a first set of spaced, heated platens, which are then driven laterally across a first pair of opposed surfaces of the cell along the weld beads formed on these surfaces. The cell is then automatically positioned with respect to a second set of spaced, heated platens, which are then driven longitudinally across a second pair of opposed surfaces of the cell along the weld beads on these surfaces, whereupon the cell is automatically removed.
