摘要：The present invention provides a method and a machine for marking an electriccable that comprises a conductive core, an insulating coating, and a varnish comprising anouter layer and an inner layer of contrasting colors, with the marking being performed byablating the outer layer of said varnish with a laser, the outer layer of varnish being basedon polytetrafluoroethylene and being 10 &mgr;m to 20 &mgr;m thick. According to theinvention the machine comprises:

a pulsed CO.sub. 2 laser (2) whose power is adjusted to obtain an energy density lyingin the range 8 J/cm.sup.2 to 15 J/cm.sup.2 at the outer layer of the cable varnish;

drive means (9) for driving the cable (4) so as to cause it to run past the laser beam(5);

guide means (13, 14, 15) for guiding the cable (4) in the vicinity of the point of impactof said beam (5) on the cable; and< P>
