摘要： The present invention relates to improvements in methods of manufacturing paper, and in particular to improvements in forming stacks of sheets and cylinder moulds for manufacturing paper incorporating security elements. The method of forming a stack of sheets, comprises the steps of making a continuous web of paper having a plurality of sets of counterpoint watermarks (30) distributed along a longitudinal direction of the web. The sets of counterpoint watermarks (30) comprise at least a first set (45) of counterpoint watermarks having a first pattern and a second set (46) of counterpoint watermarks having a second pattern different from the first pattern. The web is slit in a transverse direction of the web into a plurality of interim sheets (31, 32), each sheet comprising one set of counterpoint watermarks (30). The interim sheets (31, 32) are stacked so that the counterpoint watermarks (30) of the first and second sets (45, 46) on the stacked interim sheets (31, 32) overlap each other at a plurality of overlap points (33) and the counterpoint watermarks comprise watermarks having positive regions.

摘要： This invention pertains to security paper and methods of making such security paper. The invention comprises a light-colored base paper (42) having a non-protection area of a first thickness, and a protection area of a second thickness on at least one major surface of the base paper (42) wherein the first thickness is greater than the second thickness. The base paper (42) comprises colorant (50) whereby the protection area exhibits a translucence when viewed using transmitted light, and exhibits the colorant as a darker color indication, relative to the non-protection area, when viewed using reflected light. Transmission of light through a combination of paper fibers and the colorant, both being disposed at the protection area, is discernibly different from the transmission of light through the non-protection areas of the base paper, when viewed with a human eye.

摘要： A method of making watermarked paper, in which lace (2 or 20) is bonded to a wire cloth (3 or 30) so as to form a patterned net which is then mounted as a face wire on a cylinder mold (10) or a dandy roll (1) for a cylinder machine, and the cylinder mold (10) or dandy roll thus treated is used for papermaking. The method enables watermarked paper on which a delicate and complicated lace-like pattern is watermarked with an excellent gradation to be made readily at a low cost.

摘要： Walze für Maschinen der Papierindustrie oder dergleichen, mit einem wavenförmigen Walzenkörper, welcher durch ungefähr in Umfangsrichtung verlaufende, in axialer Richtung abwechselnd aufeinanderfolgende, hochkantstehende gerade und gewellte Bänder (16,18) gebildet wird, die durch Schweissstellen miteinander verbunden sind. Zur Schaffung von einen Durchfluss in Umfangsrichtung zulassenden Durchlässen zwischen dem Walzenkörper (12) und einem von diesem getragenen Überzugsgewebe (22) sind zwischen dem Überzugsgewebe und den radial äusseren Kanten (18a) der gewellten Bänder (18) im Bereich der Verbindungsstellen sowie in der Mitte zwischen den Verbindungsstellen an das Überzugsgewebe angrenzende Öffnungen (18b, 18c) im Walzenkörper vorgesehen, und zur Vergrösserung der freien Durchgangsfläche des Überzugsgewebes (22) liegt dieses unmittelbar auf dem Walzenkörper auf.
