Abstract

The apparatus consists of a drum whose circumferential surface coming in contact with the cable surface is provided with grooves corresponding to the marks to be formed. With each turn of the drum, the grooves are filled with colored plastic powder which, when coming in contact with the hot cable jacket, is sintered into the mark and fuses with the cable jacket.
