ABSTRACT:
There is disclosed a method for the continuous marking of electric strands with which annular markings, which are limited in axial direction, are applied to the surface of the strands by means of color jets. The color jets emerge under pressure from at least one nozzle which is driven by an electrical oscillation system, the frequency of which is controlled proportionally to a rate of withdrawal of the strands. For an easy changing of the axial distance between the markings, square pulses are fed to the oscillation system from a converter which converts electrical d.c. voltage into a square waveform signal at a specific frequency. The square waveform drives the oscillation system at the specific frequency. As a desired value, the converter is fed a d.c. voltage which is proportional to the rate of withdrawal of the strand.
