ABSTRACT:
Electroplating of the unprotected cut edges of sheet metal panels coated with an electrically non-conductive protective coating as said edges are formed on cutting the panels to shape, is effected in a highly economical manner by forming a pile of said panels so that the cut edge portions of said panels are substantially aligned with the edge portion of the electrically non-conductive protective coating, bringing at least one side face of said pile with the cut edges in contact with the electroplating electrolyte, connecting each single panel to an electroplating current source, and electroplating the cut edges of each panel. Sheet metal panels without coating or with an electrically conductive coating are electroplated in the described manner by interposing electrically non-conductive layers between the sheet metal panels at least at their margins to prevent penetration of the electrolyte between the panels and conductive contact of the panels with each other.
