Abstract:
A laser marking apparatus provides markings of enhanced readability in an outer jacket of repetitively spaced sections along the length of a moving cable which is delivered from a supply source. The cable is advanced under tension and is wound onto a take-up spool. The outer jacket is of a specified color and has an outer surface. The laser marking apparatus includes a first guide roller, a laser marker, an applicator, a coarse brush roller with a first driving mechanism, a fine brush roller with a second driving mechanism and a second guide roller. The first and second guide rollers are disposed adjacent to the supply source before the laser marker and before the take-up spool after the fine brush roller, respectively, in order to guide the cable along a path of travel so that the outer jacket passes adjacent to the laser marker. The laser marker inscribes in the outer jacket markings opening to the outer surface thereof. The applicator applies a wax, the color of which is different from and contrasts with the specified color of the outer jacket, on the outer surface of the outer jacket and in the markings.
