ABSTRACT:
According to the present invention, a submersible electrical current supply device and method of plating using said device for providing electrical current to a strip as it is continuously moved through an electroplating bath is provided. The electrical current supply device includes a housing having a slot extending therethrough with entry and exit openings and has wipers disposed at both the entrance and exit openings. In the central section of the device, electrical contacts in the form of electrical brushes are biased into contact with the strip and are provided with electrical contacts to supply current for plating to the brushes. The strip is continuously passed through the slot and contact with the brushes and electrical current is supplied by the brushes. The thickness of the slot and the length of the slot is so controlled as to provide an amount of electrical plating solution around the brushes which as a sufficiently high electrical resistance to substantially eliminate any electroplating of the material on to the brushes.
