Abstract
The invention relates to a vertical electroplating cell for processing metal strips in which the strip to be processed running from an upper conductor roll is led to a lower deflecting immersion roll and from there to a further upper conductor roll, the respective descending and ascending strip portion to be processed being subjected in a canal between vertically disposed anodes to the electrolyte flow conducted in circulation at high speed against strip running direction. In such a electroplating cell the circulation of large electrolyte amounts using the minimum possible pump energy is achieved in that the electrolyte flow directed in each case in the canals (6, 7) between the anode rows (5, 7) against the strip running direction are generated via liquid jet pumps disposed on outer canals between rear sides of anode rows and housing walls.
