For example, in the electroplating of strips using the soluble electrode method, soluble electrodes (hereinafter referred to as electrodes) made of the metal to be plated are placed on both sides or one side of a steel strip in an electrolytic bath. A negative voltage is applied, and the electrode is electrolyzed to deposit a metal, which is then plated into a strip.

トリツプ６の両面はメツキされる。 There are vertical types, horizontal types, radial types, etc. of such plating equipment, and an example of the vertical type plating equipment is shown in FIG. 3. In the figure, 1 is a plating tank filled with electrolyte, 2 and 3 are conductor rolls provided above the plating tank 1, 4 is a sink roll provided at the bottom of the plating tank 1, and 5a to 5d are plating tanks. Each pair of electrodes are arranged facing each other with a predetermined distance apart within the same. 6 is a strip to be plated, which is guided from the conductor roll 2 into the plating tank 1, passes between electrodes 5a and 5b, passes through the sink roll 4 and between electrodes 5c and 5d, and is taken out from the conductor roll 3. .

ようになつている。 By the way, in such plating equipment,
When plating, strip 6 as shown in Figure 4.
Since a large current flows through both ends in the width direction, the deposited metal 6a concentrates on the ends as shown in FIG. 5, resulting in so-called edge over coating. In order to prevent such edge overcoating, as shown in FIG. 6, edge masks 7a to 7d are provided at both widthwise ends of the strip 6 to shield it and prevent current concentration. The edge masks 7a to 7d can be moved back and forth depending on the width of the strip 6 to be plated.

In the plating equipment described above, if the equipment surrounding the electrodes remains in the conventional structure, it is not possible to sufficiently shield both ends of the strip in the width direction, and therefore edge overcoating cannot be efficiently prevented. However, since the plating strip runs in a meandering manner between the electrodes, there were problems such as the edge mask being easily damaged.

The present invention has been made to solve the above-mentioned problems, and is used in equipment for plating by running a strip with a predetermined gap between the electrode and the strip and applying a voltage between the electrode and the strip. High acid resistance, close to both widthwise ends of the strip.
The present invention provides plating equipment equipped with an edge mask made of highly wear-resistant linear insulating material in the form of a brush.

FIG. 1 is a schematic diagram showing the main parts of an embodiment of the present invention. In the figure, reference numerals 5a and 5b are electrodes that are placed opposite each other at a predetermined distance apart, and 6 is a strip that runs between the electrodes 5a and 5b in a direction perpendicular to the plane of the paper. 8 is a strip 6 between the electrodes 5a and 5b.
This is a brush-like edge mask disposed close to both ends in the width direction of the electrode, and has a length approximately equal to the length of the electrodes 5a and 5b (in the direction perpendicular to the plane of the paper). 9
are a number of linear shields made of a highly acid-resistant and highly abrasion-resistant insulating material (for example, nylon), the bases of which are fixed by a fixing member 10. Reference numeral 11 denotes a drive shaft attached to the fixed member 10, each end of which is connected to a drive device (not shown) such as a pneumatic motor.

でかつ柔軟性があるため、破損することはない。 Now, when a voltage is applied between the electrodes 5a, 5b and the strip 6 and the strip 6 is run to start plating, the shield 9 shields the widthwise ends of the strip 6 to prevent current concentration. Therefore, edge overcoating can be efficiently prevented. Further, even if the strip 6 runs in a meandering manner and enters the shield 9, it will not be damaged because the shield 9 is brush-like and flexible.
