Abstract

A method for impregnating an active paste into a fibre material in the manufacture of an electrode of a lead acid battery or cell, comprises moving a fibre material through a confined pasting zone also containing a Pb-based paste, while vibrating and maintaining a pressure on the paste, to continuously impregnate the paste into the fibre material. A paste impregnating machine is also disclosed, with a fibre material feed system, and which may use a lug along the fibre material to draw the fibre material through the paste application stage.
