ABSTRACT:
A method and apparatus for marking coated wire with alphanumeric characters is disclosed. An electrically conductive wire is surrounded with a coating; a plurality of lasers are circumferentially disposed around the wire, each laser generates a beam of coherent energy of sufficient intensity to focus on and ablate a dot-shaped area of the coating thereby creating a corresponding dot of the contrasting color. As the wire is moved past the lasers, the laser beams are sequentially triggered in synchronization with the motion of the wire to produce a matrix of dots representing alphanumeric characters appropriate for identification of the wire.
