Description of the Related Art In a steel plate for cans, a steel plate for an automobile body, a support for lithographic printing, an outer wall material, etc., it is only necessary to form a predetermined plating layer or coating layer on the functional surface, and both surfaces of the metal plate are treated in the same manner. do not have to. Therefore, in order to selectively electrolyze one side of the metal strip, a method of performing electrolysis by covering the other side of the metal strip with a paint, an adhesive tape, or the like. For example, a method of contacting one surface of the substrate with an electrolytic treatment solution. However, the method of using paint, adhesive tape, etc., requires a step of peeling paint, adhesive tape, etc. after painting, attaching tape, and electrolytic treatment.

させる。In a system in which a flexible belt is magnetically attracted to a metal band, applicable metal bands are restricted. More specifically, a flexible belt magnetically attracts magnetic materials such as ordinary steel and ferritic stainless steel, but a flexible belt applies to non-magnetic materials such as austenitic stainless steel and aluminum alloy. Cannot be magnetically attracted. Further, with a weak magnetic force, the adhesion between the metal belt and the flexible belt is not sufficient, and the electrolytic treatment liquid easily enters the gap between the two. As a result, the surface of the metal belt on the side of the flexible belt is also partially electrolytically treated, and the surface properties are significantly deteriorated.

It is sent into the tank 1 or sent out from the electrolytic tank 1. One of the drive rolls 12.13 can be a driven roll. Alternatively, when the rotation is given by the frictional force with the metal band M, both the driving rolls 12 and 13 can be replaced with driven rolls. The belt tension adjusting roll 14 is movable in the vertical direction, and adjusts the tension applied to the shielding mechanism 10 according to the amount of movement. The shielding belt 11 includes an entrance driving roll 12 and an exit driving roll 13.

持される。The metal strip M fed into the electrolytic cell 1 is given a constant tension in order to stably maintain a running state.
At this time, if the tension applied to the metal band M is too small, the driving roll 1 is moved to a position lower than the power feeding rolls 3 and 5.
2 and 13 are fixed, the drive rolls 12 and 13
The metal band M is loosened between them and tries to move to the counter electrode 2 side. On the other hand, since the shielding belt 11 is attached so that there is no slack between the driving rolls 12 and 13, a gap into which the electrolytic solution E enters is generated between the metal belt M and the shielding belt 11. On the other hand, when a sufficient tension is applied to the metal band M, a pulling force is applied to the metal band M between the drive rolls 12 and 13 in the entrance and exit directions, and the drive rolls 12 and 13 are leveled. The metal band M comes into close contact with the shielding belt 11. Since the shielding belt 11 is pressed against the metal belt M pulled in the horizontal direction by the belt holding rolls 15, 15,... Arranged inside the orbit of the shielding belt 11, the gap into which the electrolyte E invades the metal belt M. It does not occur between the belt M and the shielding belt 11. Therefore, even if the electrolytic solution E goes over the shielding belt 11, the electrolytic solution E does not enter between the metal belt M and the shielding belt 11. In this state, the metal band M and the counter electrode 2
And a voltage is applied between them, and an electrolytic treatment such as electroplating or anodic oxidation proceeds. As a result, one surface of the metal strip M facing the counter electrode 2 is electrolytically treated, and the other surface is kept untreated.

しい。It is preferable that the running speed of the shielding belt 11 is synchronized with the running of the metal band M so that there is no slip between the shielding belt 11 and the metal band M. Slippage not only increases the possibility that the electrolytic solution E enters, but also causes surface defects such as scratches on the surface of the metal strip M which has been subjected to the electrolytic treatment. However, there is a tendency to increase the traveling speed of the metal strip M in order to increase the production capacity. When the shielding belt 11 is run in synchronization with the metal belt M running at high speed, the shielding belt 1
1 meanders, and the state of adhesion to the metal band M is likely to deteriorate. In such a case, it is preferable to provide a meandering prevention mechanism 20 for restricting the movement of the shielding belt 11 in the width direction during traveling.

As shown in FIG. 2, a structure in which meandering correction rolls 21 and 22 are arranged on both sides in the width direction of the shielding belt 11 is adopted. The meandering correction rolls 21 and 22 are arranged to be inclined with respect to the width direction of the shielding belt 11, and a roll shaft protruding from one side is linked to the inclination angle adjuster 23. The inclination angle adjuster 23 is disposed so as to be movable along the width direction of the shielding belt 11. Belt end detectors 24 and 25 are arranged on both sides in the width direction of the shielding belt 11 at positions upstream of the meandering correction rolls 21 and 22 with respect to the traveling direction of the shielding belt 11. The width end positions of the shielding belt 11 are detected by the belt end detectors 24 and 25, a detection signal is output to a control mechanism (not shown), and the width direction end positions are determined by the control mechanism. When the width direction end position is deviated from the normal position, a control signal is output from the control mechanism to the inclination angle adjuster 23. The tilt angle adjuster 23 moves in the width direction of the shielding belt 11 according to the control signal, and
The inclination angles of the meandering correction rolls 21 and 22 linked to are changed.

Thus, an upward force is applied to the shielding belt 11 to eliminate the meandering. as a result,
The shielding belt 11 travels along the regular orbit, and a good contact state with the metal band M is maintained.
