<p>A process for the decoration of metals, metal alloys, in the form of extruded profiles, sheets and metal articles in general, that utilizes the transfer system. The process allows the decoration, with one only treatment, of metal extruded profiles on the four faces, independently on the shape of the profile, using suction and compressed air. The new process causes transfer to be quicker and provides an optimum result with respect to the quality of the final product. After the preliminary steps of pickling and painting, obtained by using colorless paints, the profile is wrapped up in a paper bag bearing on the surface the color and the pattern to be transferred. Air is removed from this bag. To correct paper adhesion to the support, compressed air is utilized and lastly heating. Only compressed air is utilized for sheet decoration.</p> |
