Abstract:
An improved arrangement for electrolytic cleaning of an elongated flexible metallic substrate in a heated alkaline cleaning bath comprising:(a) means to pass a longitudinally extended metallic workpiece having at least one surface to be cleaned through a containment means for a body of alkaline electrolytic solution to which solution the surface to be cleaned is exposed,(b) means to heat and maintain the electrolytic or electrochemical cleaning solution at an elevated temperature,(c) at least one electrode mounted closely adjacent the pass line of said metallic workplace within the containment means,(d) at least one unitary dielectric surface contact separating means extending at least transversely across the surface to be cleaned of said longitudinally extended metallic workplace and having a height measured perpendicular to the workplace surface greater than the arcing distance between the workplace and the electrode,(e) said dielectric surface contact separating means being compatible with an alkaline electrolytic solution and having a heat deflection temperature exceeding the elevated temperature of the electrolytic cleaning solution.
