    摘要: The invention relates to a method for verifying thickness modulations, in particular watermarks, in or on sheet material. To diminish the influence of disturbances from the surroundings and reduce the adjustment effort during production and maintenance of corresponding measuring systems, the sheet material is subjected to sound, in particular ultrasound, the sound transmitted through the sheet material and/or reflected on the sheet material is measured at a plurality of places on the sheet material, at least one value characteristic of the transmitted and/or reflected sound is generated for each of the places, and the thickness modulations are verified by comparing the values with predetermined reference values.

    摘要: A method and apparatus for recognizing foreign material (2), in particular adhesive objects, glue or joints, on or in bank notes (1), including detecting the thermal radiation (5) emanating from at least a partial area of the bank note (1): and recognizing foreign material (2) located on the bank note (1) on the basis of the detected thermal radiation (5). The invention is especially suitable for recognizing adhesive objects, in particular adhesive tape and joints, on bank notes since areas of a bank note with adhesive tape or joints differ very distinctly in their thermal properties from other areas of the bank note without adhesive tape.

    摘要: The apparatus for determining the stiffness of sheet material is provided with mechanical means which periodically touch the sheet material, causing it to vibrate. The sounds produced by the vibration are detected by a detector. From the detected sounds an evaluating device determines the stiffness of the sheet material. The sheet material is held or guided in a transport device such that it can yield to the mechanical action within certain limits in the area of contact without being irreversibly deformed.

    摘要: In an apparatus for testing value documents, such as for example bank notes, an area of the bank note is captured from different directions with the help of two optical sensors aligned symmetrically to each other. The measured values supplied by the sensors on the one hand are added up in order to obtain a total measured value which is insensitive to asymmetric effects of the value document, and on the other hand the measured values are subtracted in order to capture exactly these asymmetric effects. In this way with the help of one single apparatus there can be tested authenticity features as well as the quality of the actual state of the value document.

    摘要: The present invention relates to an apparatus (1) for examining documents (2), in particular banknotes. Therein the apparatus (1) comprises at least one light source (3), at least one spectral device (8) and at least two detection devices (9, 10, 11, 24). By means of the light source (3) the document (2) is irradiated and the light emitted and/or reflected and/or transmitted by the document (2) is subsequently divided into spectral components by means of the spectral device (8). The spectral components are separately detected by the detection devices. The spectral division of the light (4) emanating from the light source (3) can also be carried out before the light impinges on the document (2). The apparatus (1) is designed so as to individually weight the spectral components to be detected respectively by the detection devices (9, 10, 11, 24).
