Abstract

An arrangement for marking articles or workpieces, particularly hot workpieces, such as coils of sheet metal with series of symbols which are individually applied in templates. The latter are in the form of symbols applied in a cylindrical portion and in a flange-like portion of a movable angle ring which is adjustable vertically and sideways. A spray nozzle is associated with each of the portions. The angle ring is connected to a trunnion fixed in an arm which is adjustable vertically and sideways by piston-cylinder units. One piston-cylinder unit is centered in a frame which is movable on a track by driven wheels, and the piston of this unit mounts a lifting table. Another piston-cylinder unit is connected to the aforementioned arm. One vertical spray nozzle is located above the flange-like portion of the angle ring on the outer end of the arm. A horizontal spray nozzle, furthermore, is located on the lower end of the trunnion, tiltable about a horizontal axis, inside the cylindrical portion of the angle ring. The spray nozzles are immersible by the piston-cylinder unit, in basins filled with paint solvents.
