Definitions

  • 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 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.
  • 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 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.
  • 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.
  • the inventive method ( FIG. 3, 6 ) for producing fraud-proof value paper includes the stage of applying the thread 1 onto the wire 2 of the wire cylinder 3 of a paper-making machine and the subsequent stages of dewatering, when forming layers from the paper pulp 4 in the bath 5, and pressing and subsequent drying.
  • a thread made of an elastic shaped plastic and provided with protective elements 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 the wire cylinder 3 before applying the thread 1 onto the wire.
  • the width of the bottom 7 of the slots 6 is made commensurate to the width of the core of the thread 1 ( FIG. 4 ).
  • the thread 1 when applying the thread 1 its contact with the slot 6 is effected prior to the time of contact 8 between the wire and the paper pulp 4 in the bath 5 ( FIG. 3 ), and the core 9 of the thread 1 is tightly fit at the bottoms 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.
  • 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 a thread 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.
  • the thread 1 when applying the thread 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 the slot 6 after the contact 11 is achieved between the wire with the paper stock in the bath 5 and into the paper stock 4, the primary paper layer is formed on the wire surface and on the slot 6 ( FIG. 2 ) and the core 9 is disposed on the layer at the bottom 7 and inside the paper, forming the wings 10 ( FIG. 7 ).
  • protective elements e.g., microtexts, symbols, bar codes formed by de-metallization and sealed with luminescent dyes
  • 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 comes into contact with the bottom 7 of the annular slot after the wire contacts the paper stock, i.e., comes into the paper stock.
  • the pulp primary layer is formed on the wire surface, including the surface of the annular slot 6, i.e., paper layers begin to form.
  • the thread 1 is placed on layers in the slot 6, and the core 9 is disposed inside the paper sheet ( FIG. 7 ) having thickness h. Due to the sloped walls of the slot 6 that is not yet filled with the paper stock completely, the wings 10 are raised and come to the paper surface, and when a paper sheet is formed on the cylinder 3 ( FIG. 6 ) and pressed the wings 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 a thread 1 is that the area of the wings 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 the cylinder 3 of a paper-making machine and subsequent stages of dewatering, when layers of the paper stock 4 are formed in the bath 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 the central core 15 with an adhesive coating having the thickness preferably from 2 to 5 mm and the lateral elements in the form of the wings 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 the core 15 and placed at a regular and/or irregular spacing.
  • the core 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.
  • the core 15 is fixed on the surface of the paper 17, and the wings 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 ).
  • the core 15 of the thread 1 is fixed in the paper sheet having the thickness h, and the wings 16 are fixed due to dewatering at the stages of forming and pressing in the middle on the surface of the paper 17 for the purpose of creating the anti-Xerox protective effect ( FIG. 11 ).
  • the core 15 and the wings 16 of the thread 1 have a surface adhesion coating creating good adhesion of the protective thread 1 with paper fibers, which exceeds the adhesive force of fibers inside paper.
  • the wings 16 act as "foundation bolts" holding the "installation strap” on the surface.
  • the core 15, being completely disposed in the paper sheet having the thickness h 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 the thread 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.

Abstract

Dans un premier mode de réalisation de l'invention, on utilise en tant que fil un fil de plastique souple en relief auquel des éléments de protection ont été appliqués. Lors de l'insertion du fil, le contact de ce dernier avec la cannelure d'un cylindre à grille est maintenu jusqu'au contact de la grille avec la masse de papier. On pose fermement l'âme du fil au fond des cannelures de manière à assurer la fixation de ladite âme à la surface du papier pour valeurs. Grâce aux cannelures inclinées, on assure le levage d'ailettes, et pendant le formage et la compression on fixe les ailettes dans la masse du papier. Dans un deuxième mode de réalisation, lors de l'insertion de fil sa mise en contact avec la cannelure s'effectue après le contact de la grille avec la masse de papier. On dispose l'âme du fil sur une couche interne du fond de la cannelure et à l'intérieur du papier. Grâce aux cannelures inclinées, on assure le levage d'ailettes, et pendant le formage et la compression on fixe les ailettes dans la masse du papier. Dans les troisième et quatrième modes de réalisation, on utilise en tant que fil un fil se présentant comme une bande sans fin en plastic métallisé possédant une âme centrale comportant des informations de protection contrôlables visuellement ou lisibles par machine ainsi que des éléments latéraux ayant la forme d'ailettes, disposées symétriques et/ou asymétriques par rapport à l'axe longitudinal de l'âme et posées avec une périodicité régulière et/ou irrégulière.
