<p>In the method for the authentication of identification marks that are embossed on a packaging foil together with satining and the embossing of logos, a number of identification marks is embossed on-line as a pattern and read by a suitable apparatus and evaluated by means of an image evaluation method. The embossing device (1) suitable therefor includes at least two embossing rolls (2, 3, 15), a reading unit, and an evaluating unit, one of the embossing rolls (2) being driven by the motor drive mechanism (5) and having individual teeth (8) of which a number of teeth for embossing identification marks have a different shape, height, or surface structure while the remaining teeth serve for satining, and one of the mating rolls (3) being provided with circumferential rings (10). Such a method and such a device allow a relatively simpler embossing device with relatively lower requirements with regard to the embossing quality than in methods of the prior art.</p> |
