Abstract
Description
- The invention relates to a method for producing a fraud-proof value paper having improved protection characteristics.
- A method for producing fraud-proof value paper is known in the art, according to which a thread is applied to the wire of the cylinder of a paper-making machine and subsequently paper pulp layers are formed in a bath, pressed and dewatered by drying (see,
RU, C1, 2125938 - A disadvantage of the above method is insufficient quality of protection against fraud due to a low area of thread coming to the paper surface.
-
CA 2058268 disclose a method for producing papers of value having embedded security elements, in particular safeguarding threads with characters or optically active structures in the form of hologram, diffraction or interference structures, and to apparatus for carrying out the method. The invention is characterized by the fact that the security elements are incorporated true to side during papermaking and are also embedded in the paper of value so as to be accessible over the entire surface, if desired, whereby the paper surface forms a plane with the surface of the security element. - The above method does not provide high degree of protection against forgery combined with good fixing of the security thread in the paper.
- This invention is based on the objective to provide a method for producing value paper, which would ensure a larger area of a thread coming to the paper surface, and provide value paper that would ensure improved identification of its protection and, thus, to improve the quality of protection of said value paper against fraud.
- The stated objective is achieved in the one embodiment of the inventive method by that in the known method for producing fraud-proof value paper, which includes application of a thread onto the wire of the cylinder of a paper-making machine, dewatering of the paper pulp layers formed in the bath and their pressing, according to this invention the said thread is a thread in the form of an endless tape made of a metallized plastic and having the core provided with a surface adhesion coating and lateral elements in the form of wings having an adhesive coating, which are disposed symmetrically and/or asymmetrically relative to the longitudinal axis of the core and placed at a regular and/or irregular spacing, wherein the core carries protective information that may be visually checkable or machine-readable, the core being fixed on the paper surface, and the wings being fixed in the paper stock due to dewatering at the formation and pressing stages.
- Thus, in the result, value paper is produced wherein the thread is made of a metallized plastic and the core carries protective information that may be visually checkable or machine-readable wherein the core is disposed on the paper surface, and wings of the said thread are fixed in the paper stock.
- The stated objective is achieved in the other embodiment of the inventive method by that in the known method for producing fraud-proof value paper, which includes application of a thread onto the wire of the cylinder of a paper-making machine, dewatering of the paper pulp layers formed in the bath and their pressing, according to this invention the said thread is a thread in the form of an endless tape made of a metallized plastic and having the core provided with a surface adhesion coating and lateral elements in the form of wings having an adhesive coating, which are disposed symmetrically and/or asymmetrically relative to the longitudinal axis of the core and placed at a regular and/or irregular spacing, wherein the core carries protective information that may be visually checkable or machine-readable, the core being fixed in the paper sheet, and the wings being fixed on the paper sheet surface due to dewatering at the formation and pressing stages in order to achieve anti-Xerox protective effect.
- Thus, in the result, value paper is produced wherein the thread is made of a metallized plastic and the core carries protective information that may be visually checkable or machine-readable, wherein the core is disposed in the paper stock, and wings of the said thread are fixed on the paper surface.

FIG. 10 shows a cross-section of paper produced in accordance with the third embodiment of the inventive method. -
FIG. 11 shows a cross-section of paper produced in accordance with the fourth embodiment of the inventive method. - For all the embodiments the inventive method (
FIG. 3, 6 ) for producing fraud-proof value paper includes the stage of applying thethread 1 onto thewire 2 of thewire cylinder 3 of a paper-making machine and the subsequent stages of dewatering, when forming layers from thepaper pulp 4 in thebath 5, and pressing and subsequent drying. - In the first and the second embodiments of the inventive method a thread made of an elastic shaped plastic and provided with protective elements (not shown), e.g., holograms, cinegrams, optically variable systems, is used as the
thread 1. - Annular, continuous and/or
intermittent slots 6, having sloped walls, are made along the entire length of thewire cylinder 3 before applying thethread 1 onto the wire. - The width of the
bottom 7 of theslots 6 is made commensurate to the width of the core of the thread 1 (FIG. 4 ). - According to the first embodiment, when applying the
thread 1 its contact with theslot 6 is effected prior to the time ofcontact 8 between the wire and thepaper pulp 4 in the bath 5 (FIG. 3 ), and thecore 9 of thethread 1 is tightly fit at thebottoms 7 of the slots 6 (FIG. 4 ) for the purpose of eliminating its filtering ability, thus fixing the core 9 (FIG. 5 ) on the paper surface. - At the places of disposing the core of the
thread 1 the latter comes to the paper sheet surface. If deepened gaps in the wire are made in the path of theslots 6, where thethread 1 is isolated from the wire surface, then in such places thethread 1 will remain in the paper stock, being covered by paper layers on two sides. - Due to the sloped walls of the slots 6 (
FIG. 2, 4 ) thewings 10 of thethread 1 are raised upwards and then, under the influence of the formed layers of thepaper stock 4 and in the process of paper sheet compaction during pressing, they remain in the paper sheet having thickness h (FIG. 5 ) and perform the function of holding elements, as "foundation bolts". Thethread 1 is fixed on the sheet due to its adhesion outer coating that mechanically contacts the paper sheet fiber. - The
thread 1 is securely held on the paper sheet surface due to, primarily, the wings 10 (FIG. 5 ) that also have double-sided adhesion coating. An advantage of such athread 1 is that the area of the thread, which comes to the surface, is significantly larger, which enables to saturate it with complex protective elements having good visual checkability. - According to the second embodiment (
FIG. 6 ), when applying thethread 1 in the form of a thread made of an elastic shaped plastic provided with protective elements, e.g., microtexts, symbols, bar codes formed by de-metallization and sealed with luminescent dyes, the thread is brought into contact with theslot 6 after thecontact 11 is achieved between the wire with the paper stock in thebath 5 and into thepaper stock 4, the primary paper layer is formed on the wire surface and on the slot 6 (FIG. 2 ) and thecore 9 is disposed on the layer at thebottom 7 and inside the paper, forming the wings 10 (FIG. 7 ). - In order to ease reading the drawings and understanding the essence of the inventive method embodiments, on
FIG. 3 and6 reference number 12 indicated the water level,reference number 13 indicates inflow of the stock,reference number 14 indicates overflow. - The
thread 1 with the wings 10 (FIG. 6, 7 ) comes into contact with thebottom 7 of the annular slot after the wire contacts the paper stock, i.e., comes into the paper stock. At that, the pulp primary layer is formed on the wire surface, including the surface of theannular slot 6, i.e., paper layers begin to form. - The
thread 1 is placed on layers in theslot 6, and thecore 9 is disposed inside the paper sheet (FIG. 7 ) having thickness h. Due to the sloped walls of theslot 6 that is not yet filled with the paper stock completely, thewings 10 are raised and come to the paper surface, and when a paper sheet is formed on the cylinder 3 (FIG. 6 ) and pressed thewings 10 coming to the surface (FIG. 7 ) create anti-Xerox protective effect and are held on the sheet surface due to the thermoplastic adhesion between the thread coating and the fiber. An advantage of such athread 1 is that the area of thewings 10, which come to the surface, is significantly larger, which enables to saturate the thread with complex protective elements having good visual checkability. - The third and the fourth embodiments of the inventive method for producing fraud-proof value paper also include applying the
thread 1 onto the wire of thecylinder 3 of a paper-making machine and subsequent stages of dewatering, when layers of thepaper stock 4 are formed in thebath 5, pressing and drying (FIG. 3, 6 ). - A thread in the form of an endless tape made of a metallized plastic may be used as the
thread 1. The said metallized plastic tape is made of two layers of equal or not equal thickness, which are glued together, one of them having metallization on the glued side, or a mono-thread having one-side metallization may be used. - The
thread 1, in contrast to the first and the second embodiments, has thecentral core 15 with an adhesive coating having the thickness preferably from 2 to 5 mm and the lateral elements in the form of thewings 16 with an adhesive coating having the length preferably from 3 to 5 mm, the said wings being disposed symmetrically and/or asymmetrically relative to the longitudinal axis of thecore 15 and placed at a regular and/or irregular spacing. Thecore 15 carries protective information, e.g., holograms, changing-color elements, elements that are visible or invisible at different angles of view, de-metallization elements visible in transmitted light, a luminescent coating or a local sealing. - According to the third embodiment of the inventive method, the
core 15 is fixed on the surface of thepaper 17, and thewings 16 are fixed due to dewatering at the stages of forming and pressing in the middle of the thickness h of the paper 17 (FIG. 10 ). - According to the fourth embodiment of the inventive method, the
core 15 of thethread 1 is fixed in the paper sheet having the thickness h, and thewings 16 are fixed due to dewatering at the stages of forming and pressing in the middle on the surface of thepaper 17 for the purpose of creating the anti-Xerox protective effect (FIG. 11 ). - In order to implement the inventive method according to the third embodiment, the
core 15 and thewings 16 of thethread 1 have a surface adhesion coating creating good adhesion of theprotective thread 1 with paper fibers, which exceeds the adhesive force of fibers inside paper. Thewings 16 act as "foundation bolts" holding the "installation strap" on the surface. - The bases of the
wings 16, due to partial (from 0.5 to 1.0 mm) coming to the surface of the paper 17 (FIG. 10 ), create a special effect that is difficult to counterfeit. In general, it is impossible to falsify such a bulky thread without special equipment and special technologies. - Furthermore, a non-traditional form of the thread, which is visible in transmitted light, renders additional protective functions to the article.
- According to the fourth embodiment of the inventive method, the
core 15, being completely disposed in the paper sheet having the thickness h (FIG. 11 ) may carry a wide variety of both visible and machine-readable protective elements, in particular de-metallization elements visible in transmitted light, where, due to application of luminophors of various colors to different sides of the adhesive coating, when acting with ultraviolet light on transparent elements, a mixed color will be visible, e.g., on one side thethread 1 will glow yellow and on the other one - blue, then on elements transparent due to de-metallization green light will be visible. Elements carrying a magnetic material and elements detected under X-ray irradiation, etc. may be also used. - The embodiments of the inventive method for producing fraud-proof value paper may be most successfully used for commercial production of various types of securities.
