The general method for providing DC electrical contact to parts being plated by continuous reel plating is to make the cathodic contact to the parts by using a spring-loaded block, meshing metal brushes, grooved bus bar, metal sprockets or some equivalent mechanical technique. Improved performance can be obtained by making electrical contact with the parts using acid or other suitable conducting electrolyte contained in a cell which is in line with the plating cells to, in effect, "surround" the strip of parts with a total liquid infinite contact system. In essence, the cell containing the conducting electrolyte in conjunction with an inert cathodic electrode serves to complete the electrical plating circuit through the power supply and plating cell.
