Claims

[Scope of Claim for Utility Model Registration] Three plating is performed from a jet nozzle in countercurrent or forward flow to the strip passing direction between a pair of insoluble anodes 2, 2, which are arranged oppositely in the plating tank 1 with the strip S passing line in between. An electroplating device that is a plating device that blows a liquid, and is characterized in that it satisfies the following three conditions. A tapered surface T is provided at the end of each anode 2 on the side where the ejection nozzle 3 is installed, which is connected to the slip facing surface ₂₁ and is inclined toward the outside and away from the strip. A shielding plate 6 is provided on the anode 2 to close the openings on both the left and right sides of the anode gap D in the strip passing direction as much as possible.
, 6 are provided. An insulating spark prevention plate 5 for preventing direct contact with the strip S is provided on the strip facing surface ₂₁ of each anode 2, and the spark prevention plate 6 is divided into a plurality of pieces in the width direction of the anode. 5 ₁ ...
are arranged so as to be displaced back and forth in the strip threading direction so as not to be adjacent to each other.
