<p>The device has a line laser (1) emitting laser beam (7), and an ultrasonic mist generator (3) for generating limited amount of mist (17). A ventilator (15) produces an air flow that mixes the mist with air, so that individual mist waft (27) is formed with gaps. The air flow transports the mist waft along the laser beam of the line laser. A profile rail (8) is arranged with distance to the line laser such that the laser beam strikes on a base of the profile rail by an opening of the profile rail and is absorbed in the base of the profile rail, where the laser beam penetrates the mist waft.</p> |
