ABSTRACT:
A process and apparatus for coating a band of a composition about a medial portion of an electrical component lead or terminal, where a continuous ribbon of a coating composition is extruded onto a medial portion of a plurality of spaced discrete leads or terminals extending transversely from a carrier strip. The continuous ribbon of coating composition is festooned between adjacent pins to coat paste on the sides of the leads or terminals. The leads or terminals and festoonery are transported over a surface of a wheel to apply the coating composition to the underside of each lead or terminal. A cut-off blade removes the excess composition from the underside of the terminal pins, as the pins leave the surface of the application wheel.
