摘要： A method and apparatus of continuous electroplating of a strip with an alloy by passing the strip through a plating bath of the immersion type in both down-pass and up-pass with an anode being positioned in each pass so as to face at least one side of the strip are disclosed. Said anode is an insoluble anode which is spaced from the strip by a distance of about 10-50 mm, and the plating solution is blown into the gap between said anode and said strip countercurrently with respect to the movement of said strip.
