ABSTRACT:
In this arrangement a circuit is provided for generating deflection voltages for the coloring material marking the insulation of electrical conductors as the electrical conductors are extruded which compensate for distortions in the shape of color ring insulation markings when large ring spaces or high conductor extrusion speeds are employed. Two spaced spray nozzles are used to provide two streams of color material. These nozzles are disposed on opposite sides of the extruded electrical conductor, each of the spray nozzles provide one half of the color rings. The deflection voltage consists of a rectangular waveform with a semicircular top portion. A high resistance potentiometer is connected between the two spray nozzles with the wiper of the potentiometer connected to a high DC voltage source. Adjustment of the wiper renders the amplitudes of the two streams of color material equal.
