slot at a flow rate of not less than 150 m 3 per hour the electrolyte issuing from the outlet slot 10 completely fills the gap s between the electroplating plate 7 and the strip 1 and is diverted by the strip 1 towards the longitudinal edges of the strip 1 the electrolyte then flows into the lower portion of the tank 4 and is once again pumped back into the anode housing 5 by the pump 8 the dimensions of the outlet slot 10 the delivery rate of the pump 8 and the gap s between the electroplating plate 7 and the metal strip 1 should be chosen such that the electrolyte essentially emerges only at the longitudinal edges of the metal strip 1 during the process of deposition the coating metal for example zinc or nickel which is located in the basket 12 gradually dissolves since during this process the spacing between the coating metal 13 which functions as the anode and the strip 1 does not however change and since furthermore the pressure of the electrolyte flowing out of the outlet slot 10 holds the metal strip 1 at a constant spacing with respect to the electroplating plate 7 a very uniform deposit of coating metal is produced on the metal strip 1 the coating metal which is gradually being consumed is replenished.
