A device for galvanically depositing a metal coating on a side of a metal strip includes an anode housing which is connected to a power supply and includes one or more planar, vertical electroplating plates. The metal strip is also connected to the power supply and serves as a cathode, and is supported for vertical movement past the electroplating plate a short distance therefrom and parallel thereto. The electroplating plate includes a generally vertical outlet slot which permits electrolyte to flow out of the anode housing to the region between the electroplating plate and metal strip, and a pump returns the electrolyte to the anode housing. In a preferred embodiment, the outlet slot tapers downwardly and is inclined at a small angle to a vertical reference.
A device for galvanically depositing a metal coating on a side of a metal strip, including an anode housing which is connected to a power supply and includes at least one substantially vertical and flat electroplating plate, said metal strip being connected to said power supply, serving as a cathode, and being supported for substantially vertical movement past said electroplating plate parallel thereto and spaced slightly therefrom, said electroplating plate having at least one outlet slot, an electrolyte provided in said anode housing and flowing through said outlet slot into the space between said electroplating plate and said metal strip, and pump means for pumping said electrolyte back into said anode housing, the improvement comprising wherein said electroplating plate has a single said outlet slot which is provided in a center region thereof, extends substantially in the direction of movement of said metal strip, is inclined with respect to a vertical reference by an acute angle of approximately 4.degree.-8.degree., and tapers in width toward the lower end thereof.
