ABSTRACT:
The present invention is characterized in that, a mandrel is rotated continuously as strip fed electrical terminals are strip fed continuously to the mandrel, and partially wrapped against the mandrel and exited from the mandrel, a conduit supplying plating fluid under pressure opens into a plurality of nozzles on the mandrel, anodes are mounted within the nozzles for reciprocation into and out of the interiors of the terminals that are against the mandrel, the conduit supplies plating solution under pressure to the nozzles, the nozzles inject plating solution into the interiors of those terminals in which the anodes are received, a source of electrical current supplies electrical current flowing from the anodes, through the plating solution and to the interiors of those terminals in which the anodes are received, and the anodes are constructed for withdrawal from the interiors of those terminals prior to those terminals exiting from the mandrel.
