Abstract
In order to avoid an edge-effect (increased electrical field line density at the edges of electrolytically to be processed work pieces) during the electrolytic processing of work piecesin a conveyorized system, the electric currents originating from various counter electrodesin the plant are set to values in function of the electrolytically to be processed surface areas of the work piecesas far as they are located directly opposite the respective ones of the various counter electrodes. Moreover, the distance between the work piecesand the counter electrodesis chosen to be 50 mm maximum. Meansfor individually controlling and adjusting every single current supply unitof the counter electrodesare provided for this purpose. Said meansare configured in such a manner that the respective electric currents originating from the various counter electrodesare settable to values in function of the electrolytically to be processed surface areas of the work pieces, as far as they are located directly opposite the respective various counter electrodes
