Abstract
A method and apparatus for applying dye marks to a line at predetermined fixed increments. An unmarked line is wound around a roller tube which has a slot formed therein communicating with the interior of the roller tube. A vaporized dye is supplied to the interior of the roller tube and exists through the slot and the roller tube. The disperse dye contacts and penetrates the portion of the line overlying the slot to produce a dye mark on the line at predetermined increments equal to the circumference of the roller tube.
