ABSTRACT:
A process and apparatus is provided for filling tubular plate positive electrodes for use in lead-acid secondary cells with lead oxide particulate material in a highly fluid slurry form wherein tubular plate positive electrode assemblies comprising a plurality of substantially lead spines aligned on a conductive bar, each spine enveloped by a porous tubular sheath, are footed prior to being filled with lead oxide particulate material in a highly fluid slurry form. The foot according to the present invention comprises a plurality of aligned projections extending from a base portion and slurry access ports penetrating the foot. Each projection engages a spine within its spine recess and is itself engaged within a tubular sheath, and each projection is provided with at least one slurry access port. Lead oxide particulate material in a highly fluid slurry form is introduced into the annular space between each spine and its corresponding tubular sheath through the slurry access ports penetrating the foot.
