ABSTRACT:
An improved method of beading deformable electrodes is provided which method comprises forming a plurality of spaced depressions, preferably simultaneously, as through the use of a novel beading tool, in at least one surface of a deformable electrode and then adhesively binding nonconductive beads in said depressions so as to collectively form a nonconductive separator on said surface. The method is applicable for use with metallic electrodes such as sintered silver or nickel or cadmium plaque electrodes, the surfaces of which are not subject to easy plastic flow at relatively low pressure, in contrast to silver chloride plates. Preferably the depressions are hemispherical and the beads are spherical so that a substantial portion of each bead extends outwardly from the beaded electrode surface. The dimpling can be carried out effectively through the use of an improved novel tool which comprises a flat plate having a plurality of spaced apertures extending from the top to the bottom thereof at about a 90.degree. angle to the main plane of the plate. A plurality of pins are releasably disposed in these apertures, one per aperture, each pin having an expanded head or the like to releasably retain it in the plate and a depression-imparting protrusion at the lower end thereof. The protrusion is preferably hemispherical and extends below the bottom of the plate. The tool also includes means for releasably locking the pins in the plate. Such means can include a second flat plate parallel to and above the first plate and releasably secured thereto by a hinge and latch to trap the pinheads therebetween. The tool simultaneously forms a plurality of spaced depressions in the surface of the electrode when forced thereagainst, as by a press, as by hammering or by other suitable pressure imparting means. The method and tool are simple and effective in providing the adhered bead separator on the face of the electrode.
