Definitions

  • the instant invention relates to a device and method for producing paper protected against counterfeiting and to paper produced by this method.
  • a method and paper-making machine are known for the production of paper protected against counterfeiting, in accordance with which a protective strip is fed onto a cylinder mould outside a fibrous mass in such a manner that it is placed on raised portions on the cylinder (projecting elements).
  • a paper layer is not formed on the side facing the cylinder, so that the thread turns out to be freely accessible to the surface exactly in these places (see EP 0 059 056 A1, 1 September 1982).
  • this method does not make it possible to form paper with wide threads without defects in the reverse side of the paper sheet, the side which is not in contact with the cylinder, since one cylinder is used in this method.
  • the analog most similar to the invention being described is a method and device for producing paper protected against counterfeiting, in which a first paper sheet is formed with a protective strip having a width of more than 2 mm, which is embedded into this sheet during its formation on a cylinder mould with the formation of zones of free access on the face side of the sheet on projecting elements, a second paper sheet which does not contain a protective strip and which after completion of the formation of the first paper sheet is applied onto the rear side of the first paper sheet is formed parallel with the formation of the first paper sheet with a protective strip and the sheets are connected to close defects on the rear side of the first paper sheet, with subsequent pressing and drying (see RU, 2125938 C1, 10 February 1999).
  • the protective strip is embedded into the first paper sheet during its formation on the cylinder in the following manner: the protective strip is fed onto projecting elements of the cylinder outside a fibrous mass.
  • the formation of a paper layer around the protective strip takes place during the passage of the cylinder through a bath with a paper mass, and zones of free access (windows) are formed in the zones where the strip is in contact with the projecting elements.
  • zones of free access are formed in the zones where the strip is in contact with the projecting elements.
  • Elements having the form of a rectangle are used as the projecting elements. These elements are obtained by stamping the grid of a cylinder along its circumference in a predetermined zone of embedding the protective strip and the surface of the cylinder has the form of railroad ties.
  • the object of the claimed invention is to create a method and device for producing paper, which would provide the possibility of enhancing the degree of protectiveness of the paper against counterfeiting and of improving its quality as a result of using a protective strip of any width (up to 20 mm), and also producing paper with windows having a regular or irregular geometrical shape, wherein windows with a sequential combination of different figures may be used, the width of the windows may be equal to the width of the protective strip, or also be narrower or wider and the distances between the windows may be selected to be any independent of the diameter of the cylinder.
  • the aforesaid object in accordance with one aspect of the invention is achieved in that in a method for producing paper protected against counterfeiting, a first paper sheet with a protective strip having a width of more than 2 mm is formed.
  • the strip is embedded into this sheet during its formation on a cylinder mould with the formation of zones of free access on the face side of the sheet on projecting elements, a second paper sheet being formed in parallel with the formation of the first paper sheet with a protective strip, the second paper sheet not containing a protective strip and after completion of the formation of the first paper sheet is placed on the rear side of the first paper sheet, and they are connected to close the defects on the rear side of the first paper sheet, subsequently pressed and dried, in which in accordance with the invention, the protective strip is embedded into the first paper sheet during its formation after the formation of zones of free access with the simultaneous creation of a fibrous layer with a mass comprising 35-50% of the mass of the first paper sheet.
  • Water-impermeable elements may be used as the projecting elements.
  • An additional protective element such as watermarks, protective fibers, chads or combinations thereof, etc. is introduced into the first paper sheet comprising the protective strip.
  • an additional protective element such as watermarks, protective fibers, chads or combinations thereof, etc. may also be introduced into that sheet.
  • the protective element introduced into the first paper sheet, obtained, for example, by the method of stamping a forming grid or filigree, may form with the zones of free access a single figure (visual figure), visible when the paper is looked at in transmitted light.
  • This figure may also be text, a combination of letters or something similar.
  • an additional protective element such as watermarks, protective fibers, chads or combinations thereof, etc., is introduced into both the first paper sheet comprising a protective strip and into the second paper sheet, which does not comprise a protective strip, in the process of their formation.
  • a protective strip with a width of 2 - 20 mm is used.
  • a protective strip is used that is provided with an additional protective feature, for example, printed and/or metallized and/or demetallized symbols and/or optically changing effects, diffraction pictures, holograms, interference effects and/or magnetic codes and/or fluorescent substances, etc.
  • the second subject matter of the instant invention is paper protected against counterfeiting and made by the method described above.
  • Paper protected against counterfeiting in accordance with the invention, consists of a first paper sheet with a protective strip having a width of 2 - 20 mm, a fibrous layer positioned on the face side and having zones for free access (windows), which have a regular geometrical form such as a rectangle or square or rhombus or triangle or circle or ellipse or star or an irregular geometrical form, or combinations thereof.
  • the protective strip in the first paper sheet is provided with an additional protective feature, for example, with printed and/or metallized and/or demetallized symbols and/or optically changing effects, diffraction images, holograms, interference effects and/or magnetic codes and/or fluorescent substances.
  • the paper consists of two paper layers in which the first paper sheet containing a protective strip also comprises an additional protective element, such as watermarks, protective fibers, chads and combinations thereof, while the second paper sheet, not containing a protective strip, comprises an additional protective element, such as watermarks, protective fibers, chads or combinations thereof.
  • the paper according to the invention may also consist of two paper layers, wherein the first paper sheet comprises a protective strip, while the second paper sheet does not comprise a protective strip, which include therein an additional protective element ⁇ watermarks, protective fiber, chads or combinations thereof.
  • the paper acquires additional protective properties during the formation of zones of free access to a thread by using a light watermark obtained by the method of stamping a forming grid or filigree, which have a length greater than the width of the protective strip.
  • the zones of free access on the strip visible in reflected light, and elements of the watermark, which are visible in transmitted light, form a single image (visual image).
  • a device for producing paper used to carry out the method in accordance with the invention and comprising: a cylindrical paper-making machine to form a first sheet, comprising a cylinder mould, which has a grid with elements projecting relative to the general surface of the cylinder and a bath for accommodation of the paper mass; and a device for forming a second sheet, also comprising a forming grid, in accordance with the invention the surface of the aforesaid elements has water-impermeable regions.
  • the device for forming the second sheet may be either a cylindrical or a planar device for forming a paper sheet. Wherein the aforesaid projecting elements have a regular or irregular geometrical form or combinations thereof.
  • the inventors of the instant invention have established that the formation of a fibrous layer takes place over the whole area of the cylinder except for the water-impermeable regions, which provides the possibility to form a fibrous layer with the simultaneous formation of shaped zones of free access (windows) from a lengthy fibrous mass, after which embedment of the protective strip takes place with the subsequent formation of the reverse side of the first paper sheet in order to provide the possibility to increase the protectiveness and enhance the design of the paper.
  • FIG. 1 An example of a device for producing paper is shown in Fig. 1, the device comprising a cylinder mould 1 having projecting elements 2 formed by stamping a grid, like convex elements above the general surface of the cylinder. However, these elements may be formed with the aid of filigree, and also by stamping a grid with the formation of convex zones as compared with the general surface of the cylinder. Elements 2, on the surface of which water-impermeable regions 3 are made, are shown in the drawing. These regions may have a regular geometrical form, such as a rectangle, square, rhombus, triangle, circle, ellipse or star, and also an irregular geometrical form or a combination thereof.
  • the device for formation of a second paper sheet 14, schematically shown in Fig. 1, in this example is a flat-grid forming device, comprising a forming grid 12 and a device 13 for filling in the paper mass.
  • the method in accordance with the invention comprises the following steps.
  • the water-impermeable regions are loaded into the bath 4 with the paper mass 5.
  • a paper layer is formed on the grid of the cylinder with a mass that is 35 - 50% of the mass of the first layer with the simultaneous formation of zones of free access (windows) of a corresponding geometric form.
  • a protective strip 9 is fed onto the grid cylinder at level 7 of the paper mass, after which the formation of the paper layer on the reverse side of a first paper sheet 10 is continued to the level 6.
  • a paper sheet with windows 11 for free access to the protective strip 9 is obtained.
  • a second paper sheet 14 is formed on another device, the second sheet being firmly connected by known methods to the first paper sheet 10 in order to close the defects formed on the reverse side of the first sheet. Further an obtained multilayer sheet 15 is pressed and dried on the paper-making machine.
  • a stamped grid of the cylinder 1 and a forming grid 12 are used, while protective fibers and/or chads are added to the paper mass before forming the first and/or second paper layer.
  • Fig. 2 shows a view of the paper in transmitted light, wherein the zone of free access forms with the watermark a single visual image.
  • the proposed method and device for producing paper protected against counterfeiting make it possible to produce paper with higher physicomechanical strength indexes by using a more lengthy fibrous mass, since in the proposed method the direct deposition of fibers onto the surface of the cylinder takes place, including the zones located between the windows.
  • the method and device for producing paper protected against counterfeiting in accordance with the invention and paper produced by this method may find use in the production of different kinds of paper, such as banknote, document, check, passport, excise, et alias, protected against counterfeiting with a protective strip.
