  • Patent number: 4318430
    Abstract: Apparatus for manufacturing rechargeable electrochemical cell electrodes of the type having a metal grid substrate and an electrochemically active material carried thereby, in which a continuously moving web of the metal grid substrate is fed to a paste applicator where active material is loaded into the spaces of the grid, the loaded grid then being passed through a set of driven sizing rollers for compressing the active material and grid and for extracting excess liquid, and thereafter being passed through a set of die rollers which cuts and trims the electrodes to the desired form. During transport of the continuous web, webs of disposable material, such as porous pasting paper, are conveyed in contact with one or both sides of the substrate as it progresses through the manufacturing stations.
