ABSTRACT:
A wire plating machine includes a tank whose interior walls are covered with insulation and which contains an electrolyte bath. Positioned on the bottom of the tank is a positive insulated electrode which creates positive ions, e.g., tin. A wire is drawn through the tank in a relatively straight line and is given a negative charge, while still in the bath, by passing it into a series of insulating housings along its path of travel. Within the housings there are elongated rods in contact with the wire and connected to a negative potential via shunt straps that pass through insulated tubes out of the bath to a voltage source. Upon leaving the bath, excess electrolyte is removed from the wire and it is subjected to a neutralizing rinse. Then the wire is wound up on a capstan of an intermediate drawing machine. If desired, the wire is reduced in the drawing machine and then passed, first one way and then the other, through the electrolyte bath again, while being periodically recharged in additional insulating housings along its path of travel. This reduced wire with additional plating is wound up on a second capstan of the drawing machine. Thus, the power needed to move the wire is produced by the drawing machine and the wire is recharged without having to remove it from the bath.
