  • Electrolytic cell
    Patent number: 4129492
    Abstract: An electrolytic cell, particularly one for use in the production of foil, in which the cathode comprises a rotating drum having a conforming anode spaced therefrom with a melded fibre interlayer. The interlayer remains stationary while the drum rotates over the fibrous surface, thereby breaking up the depleted barrier layer adjacent the cathode, avoiding arcing and reducing the tendency for the cathode deposit to grow in a modular manner.
