THE METHOD OF APPLYING LONGITUDINAL IDENTIFICATION STRIPES TO FILAMENTARY INSULATED CONDUCTORS, WHICH COMPRISES ADVANCING SUCH A CONDUCTOR LONGITUDINALLY PAST A TUBULAR NEEDLE HAVING ITS DISCHARGE END SPACED CLOSELY TO THE SURFACE OF THE INSULATED CONDUCTOR AND HAVING A BORE WITH A MAXIMUM DIAMETER OF ABOUT .030 INCH, SUPPLYING CONTINUOUSLY TO SAID NEEDLE A FREE-FLOWING, RAPIDDRYING COLORING FLUID HAVING A VISCOSITY OF THE ORDER OF ABOUT 5 SECONDS MEASURED BY THE STORMER METHOD, MAINTAINING THE COLORING FLUID SUPPLIED TO SAID HOLLOW NEEDLE AT A CONSTANT PREDETERMINED PRESSURE WHEREBY A FINE, HIGH VELOCITY STREAM OF THE COLORING FLUID IS DIRECTED TOWARD THE ADVANCING INSULATED CONDUCTOR AT A CONSTANT RATE OF FLOW AND IMPINGES UPON THE SURFACE OF THE INSULATED CONDUCTOR, AND CORRELATING THE SPEED OF THE INSULATED CONDUCTOR WITH THE RATE OF FLOW OF THE STEAM OF COLORING FLUID SO THAT THE STEAM PRODUCES ON THE CONDUCTOR A CONTINUOUS STRIPE HAVING A PREDETERMINED WIDTH.
