Definitions
- the invention relates to a method for producing a security paper for security or value documents, which has at least one through opening with characteristic irregularities in the edge region.
- the invention further relates to a paper screen for the production of such security paper as well as a form element for use in such a paper screen.
- Security documents or documents of value are often provided with various authenticity features for the purposes of security, which permit verification of the authenticity of the security paper or value document and at the same time serve as protection against unauthorized reproduction.
- security paper refers to the unprinted paper, which is usually present in quasi-endless form and is processed further at a later point in time
- valuable documents are in particular banknotes, stocks, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other counterfeit-sensitive papers, such as passports and other identification documents, as well as product security elements, such as labels, seals, packaging and the like ,
- security paper or "value document” below includes all such documents and product security means.
- the document WO 95/10420 describes a value document into which a through opening is punched after its production, which subsequently woked with one opening on all sides superior cover is closed on one side.
- the cover film is transparent at least in a partial area, so that when attempting to copy the document of value, the substrate shines through and reproduced by the copying machine accordingly. In this way counterfeits can be easily detected.
- the hole created by punching can be generated by a counterfeiter as well.
- this area can subsequently be punched out analogously to the real value document and closed again with a suitable cover film. Such counterfeits are difficult to recognize.
- Edge area characteristic irregularities on the finished paper can not be subsequently produced.
- the irregularities are manifested in particular by the absence of a sharp cutting edge or by irregular attachment of fibers in the edge region and by protruding into the opening of individual fibers. Openings produced in this way have a similarly high security value as a watermark produced during papermaking or a security thread embedded in papermaking.
- the present invention seeks to provide a generic method that avoids the disadvantages of the prior art.
- the method is intended to combine the high security against forgery of the openings produced during papermaking with high reproducibility during production.
- the invention is based on the idea not to produce the irregularly bounded opening by a complete displacement of the pulp already in the sheet formation, but rather to initially create only the outline of the desired shape of the opening in the form of thin spots in the paper web in the sheet formation.
- the paper web has in these areas then only a small initial strength, so that with the
- Thin points predetermined breaking points are introduced into the paper web, by means of which the enclosed area can be separated out of the still moist paper web in the subsequent dewatering step.
- the method now proposed has less susceptibility to variations in sheet formation and changes in the opening shape due to the mobility of the still wet pulp, so that the desired Openings very controlled and reproducible can be introduced.
- irregularly edged openings with complex outline shapes can be produced with the aid of this method.
- the paper web is formed on a paper screen with applied linienf örmigen form elements that lead to the formation of thin spots in the paper web during sheet formation.
- the line-shaped form elements preferably form a substantially closed curve.
- substantially closed means that the curve formed by the form elements can be completely closed, or can also contain individual curve sections with small intermediate webs therebetween, by means of which the detachment of the area enclosed by the curve sections is not prevented Also, individual curve sections remain completely fiber-free, wherein the region enclosed by the thin areas and fiber-free areas area is still connected to the wet paper web and according to the invention is separated out in the dewatering step from the paper web.
- the mold elements are advantageously formed by applied to the paper wire linear metal or plastic moldings.
- the moldings can be soldered, welded or glued to the paper wire, for example.
- the shaped elements are formed by a line-shaped sealing compound firmly connected to the paper screen.
- substances which can be applied to the paper screen in the tough state and which firmly bond to the paper screen after an active or passive curing process are suitable as sealing compounds.
- the sealing compound may be formed by an epoxy resin-based adhesive, a thermosetting solder paste or a UV-cured adhesive.
- a UV-curing adhesive is first applied over a large area to the paper web and then applied to a mask in desired areas with UV radiation and cured. The uncured part of the adhesive is washed out, so that a molded element of UV-cured sealing compound with the desired shape is formed. Further advantageous embodiments and details are described in the publication WO 03/025281, the disclosure content of which is included in the present application in this respect.
- the line-shaped form elements preferably have a line width between 0.3 mm and 5 mm, particularly preferably between 0.5 mm and 3 mm.
- the height of the line-shaped form elements is preferably between 0.5 mm and 2 mm, and in particular between 0.8 mm and 1.5 mm. It is understood that the optimum values for the line width and height can be determined by comparative experiments depending on the desired irregularity of the edge contour, the size of the motif or the properties of the paper pulp.
- the line-shaped form elements and thus the generated opening form a shape with a complex outline, in particular a graphic motif, such as a floral or leaf motif, or a more complicated geometric shape, such as a multi-pointed star.
- the paper screen is particularly advantageous to a paper strainer for a rotary screen.
- the thin spots are preferably generated in sheet formation with only a few superimposed fibers. This ensures that the shapes produced on the one hand can not slip off the screen when the paper web is being taken off, but on the other hand that the strength of the thin areas is extremely low, so that they act as predetermined breaking points in the subsequent dewatering step.
- the at least one opening is expediently closed on at least one side of the security paper with a film element. In some designs, the opening is even closed on both sides with a foil.
- the process of the invention is suitable for all substrates with aqueous foliation of natural or synthetic fibers, such as cotton combs, pulps, fibers of organic or inorganic plastics, as well as their blends.
- FIG. 1 is a schematic representation of a banknote from a security paper according to an embodiment of the invention
- FIG. 3 is a plan view of a section of the paper wire of the paper machine of Fig. 2 with a soldered metal mold part
- FIG. 4 shows a plan view of the lifted off from the paper wire and provided by means of the metal mold part of FIG. 3 with thin spots paper web
- FIG. 5 shows a cross section through the paper web of Fig. 4 along the
- Fig. 6 shows a cross section of the paper web of Fig. 5 after the dissolution of the area bounded by the thin areas.
- FIG. 1 shows a schematic representation of a banknote 10 with a through opening 12, which is closed by a transparent foil strip 16.
- the through hole 12 was doing produced during the manufacture of the security paper used for the banknote 10 and has a fibrous, irregular edge region 14.
- Such a rim 14 is characteristic of openings already made in sheet formation and can not be subsequently produced by punching or cutting the paper.
- Fig. 2 shows first a portion of a round screening paper machine 20, as it is used for the production of security papers.
- 3 shows a plan view of a section of the round screen 22 of the paper machine 20.
- the round screen paper machine 20 comprises, in addition to the round screen 22, a pickup roller 24, via which a pick-up felt 26 is stretched.
- line-shaped metal moldings 28 are soldered onto round sieve 22, which form a closed curve in the form of the outline of the opening to be produced, for example the star motif 12 of FIG.
- the height of the line-shaped metal moldings 28 is selected so that in the region of the thin spots 34 after sheet formation only a few fibers are superimposed, but does not produce a continuous hole in the paper web becomes. In the area of the thin spots 34, the paper web therefore has only a low initial strength, so that the thin spots represent predetermined breaking points. On the other hand, the paper web is also continuous in the area of the thin spots 34, so that the outline shape formed by them does not slip off the round screen 22 when the still wet paper web is taken off.
- the paper web 32 is dewatered in the press section. During this process, forces act perpendicular to the paper web extension (arrow 36), which cut out the inner region delimited by the thin points 34 acting as predetermined breaking points from the still moist paper web.
- the result is a continuous opening 12 with characteristic Randunregelwhikeiten 38 (Fig. 6), whose shape is determined by the outline contour formed by the thin spots 34 and thus by the shape of the metal moldings 28.
- the contour of the opening 12 in the continuous paper web is generated reproducibly, without being adversely affected by fluctuations in the sheet formation and the inherent mobility of the wet pulp.
- the metal moldings 28 have a stroke width of 2 mm and a height of 1 mm. It is understood that depending on the desired irregularity of the edge profile, the size of the motif or the properties of the paper pulp, other values for the line thickness or the molding height may be considered.
- the molded parts 28 may also be made of a hard plastic instead of metal, or they may be applied to the wire by a tough state and subsequently hardened sealing compound may be formed.
