    Abstract: The method for the recognition of an authenticating mark on the surface of a packaging foil or an article by means of visual and/or electronic recognition means through an envelope is carried out by ultrasonic or X-ray techniques. In particular, the authenticating mark comprises at least one embossed authenticating mark having finest structures in the micrometer range, and the surface of the packaging foil or of the area of the article in which the authenticating mark is embossed is metallized or made of metal. In such a method, the package need not be opened or destroyed for inspection and the authenticating marks are not distinguishable from the outside in visible light.

    Abstract: The device for satinizing and embossing packaging foils comprises at least two embossing rollers that are each provided with a toothing consisting of individual teeth, the pyramidal teeth having an essentially rectangular horizontal projection, and the sides of the teeth being essentially parallel and perpendicular, respectively, to the longitudinal axis of the embossing roller. In contrast to the prior art, the opening angle (α) between the radially aligned adjacent tooth flanks (31FR, 32FR) is smaller than the opening angle (β) between the axially aligned adjacent tooth flanks (32FA, 33FA), and the tooth height (X) in the radial direction, measured from the tooth tip (ZS) to the tooth bottom (ZG1), is greater than the tooth height (Y) in the axial direction measured from the tooth tip (ZS) to the tooth bottom (ZG2). This dimensioning and arrangement of the teeth provides an improved gearing with a reduced specific pressure as well as an improved processing of the paper part of the foil that results in its better folding, curling, and tubing behavior.

    Abstract: In the method for creating colour patterns for technical applications and visible for the human eye by means of diffraction gratings through light irradiation, diffraction grating arrays are produced directly on a solid body surface in a laser microstructuring process by at least one laser installation in the nanosecond range or in the pico- or femtosecond range, each diffraction grating array being composed of subareas (81) whose longitudinal dimension has a value below the resolving ability of the eye and which contain at least one pixel (81, 82, 83), a pixel being a limited diffraction grating structure for producing a spectral colour. The direct application of such colour-producing diffraction grating structures to a solid body surface enables a large variety of decorative and authentication possibilities ranging from embossing tools to jewellery.

    Abstract: The foil embossing device (1) comprises an embossing roller (2L) and two counter-rollers (3, 4), one of the rollers (2L) being driven by a drive (6) and the rollers having a configuration where the teeth, rings, or ridges project from the base cylinder, at least the embossing roller (2L) having teeth (5, 5B) that project from the base cylinder and at least partly also serve for driving the counter-roller. To increase the uniformity of the embossing of the foil, the embossing roller (2L) has a diameter (D 2 ) that is reduced by 0.02 to 0.20 mm over a certain length (S d ) that is at least the same as the width (7 d ) of the foil. The length of the reduced diameter is preferably chosen so as to exceed the width (7 d ) of the foil being printed. Due to this depression (S), such a device allows a perfectly uniform embossing of foils of any kind independently of the design of the embossing rollers.

    Abstract: Beim Verfahren zur gezielten Strukturierung mindestens eines Bereiches einer Festkörperoberfläche mit einem vorzugsweise Femtosekunden-Laser entstehen gitterartige Strukturen im Nanometer-Bereich (Ripples, LIPPS), wobei die gezielte Strukturierung dadurch erzeugt wird, dass die Laserstrahlung polarisiert wird und zwischen der Polarisationsebene und der Oberfläche eine Relativbewegung durchgeführt wird, um die gitterartigen Strukturen anzuordnen. Dadurch können beispielsweise Authentifikationsmerkmale auf relativ grossen Flächenbereichen, beispielsweise von Druckwalzen, erzeugt werden, die dann auf Verpackungsfolien geprägt werden können. In einem weiteren Anwendungsbereich kann mit obigen Verfahren die Oberfläche von Werkstücken derart verändert werden, dass durch die geordneten gitterartigen Nanostrukturen spanabhebende, ölrückhaltende oder haftende Eigenschaften verbessert werden können.
