ABSTRACT:
A continuous strip is electrochemically processed in an electrolytic processing bath using either a thin flexible or resilient dielectric wiping blade or an open web, plastic mesh to wipe bubbles of gas from the surface, sever dendritic material, if such is present, and to remove a surface layer of partially depleted electrolytic solution, replacing with fresh solution and to stabilize strip portions extending between support rolls. The resilient dielectric wiper blade is preferably used with perforated anodes which allow fresh electrolytic solution to flow into the space between the anodes and the strip surface after being expelled by passage of the strip past the wiping blade. The wiping blades may also be angularly oriented with respect to the strip to increase the wiping effectiveness. The open web, plastic mesh wiper is particularly effective in providing the best spacing between the strip and the electrodes to prevent arcing and also prevents catching of any filter cloth used over the electrodes upon the strip. Electrodes in a circular configuration may be used.
