Definitions

  • the present invention is extremely simple, it is not easily duplicated by a forgerer because of the need to print a unique pattern during the paper making process.
  • the anti-counterfeit pattern can easily be changed by the manufacturer and the capability of changing the anti- counterfeit pattern is not something that a forgerer would normally have because of the expense of the machinery required to mass produce multi-ply paper containing an anti-counterfeit pattern coded on an interior surface of one or more of the plies.
  • the system is not foolproof, it will significantly deter forgery because of the substantial capital investment that would be required to provide counterfeit paper with the virtually limitless anti-counterfeit patterns provided by the invention.
  • This capability to encode items such as labels in specific production lots for specific customers is a unique feature.
  • the labels can then be correlated with a specific production order at any future date.
  • individual products made with the encoded paperboard, packaged with the encoded paperboard, and/or labeled with the encoded paperboard can be quickly authenticated at a later date by comparing the code with a record of codes kept in a data bank.
  • Fig. 1 is a top perspective view, partially cut away, of a multi-layer paper/paperboard sheet in accordance with the invention
  • each ply is formed of conventional paper or paperboard web.
  • the layers 12, 13, and 14 are laminated together using techniques that are conventional in making multi-ply paper and paperboard.
  • an anti-counterfeit coded pattern 16 is applied to one of the plies 12 or 13, prior to the lamination step in production.
  • the coded pattern 16 may be applied in any desired fashion and thus requires little, if any, change in the produc ⁇ tion apparatus used in producing multi-layer products.
  • the anti-counterfeit coded pattern 16 preferably is uniquely correlated in a predetermined fashion to a selected "characteristic" of the paper or the goods/services to be associated with the paper.
  • the principles of the invention are particularly useful in the production of labels for clothing articles such as jeans which are commonly subject to counterfeiting.
  • the invention provides a simple way of correlating a characteristic, such as style, size or lot number, of the jeans produced by the manufacturer to a unique anti-counterfeit pattern embedded within the paper label. An inspector seeking to determine whether a particular pair of jeans is counterfeit or not, knowing the preselected characteristic of the jeans can determine whether or not a particular pair of jeans is a counterfeit simply by observing the anti-counterfeit pattern on the edge of the label.
  • the tickets can be coded by the event or by date. That is, a ticket for a particular concert would have a different anti-counterfeiting code than the tickets for a different concert. Likewise, the tickets can be coded by date.
  • those who are inclined to produce counterfeit paper products such as labels and tickets will lack the resources to manufacture the paper with the code, but even if they can produce the paper, they are extremely unlikely to have the ability to match the anti- counterfeit code and the event. If the manufacturer maintains secret the correlation between the anti-counterfeit code and the product/service characteristic that is coded, the counterfeiter cannot duplicate the proper anti-counterfeit pattern. The effect is to greatly simplify the detection of counterfeit merchandise and/or paper which in turn will deter countefeiting.
  • the paper 10 of Figure 1 may include printed matter
  • This printed matter which may be in the form of alphanumeric characters, designs, pictures, etc., carries the intelligence of the finished pro- duct, that is, is the ticket, label, sports card, or the like.
  • the chemical stock from the head box 28 is dispersed on a continuous conveyor belt 34 made of fabric and generally known as the bottom wire.
  • the wire 34 moves around a multiplicity of rollers (not numbered) in a clock-wise direction.
  • the filler stock within the head box 30 likewise is dispersed onto a continuous filler ply wire 36 which moves in a counterclock-wise direction with the filler ply and bottom ply being laminated together where the wires 34 and 36 are in contact with each other.
  • a continuous backing wire 38 supports the filler ply as it turns the corner to move into contact with the bottom wire 34.
  • the anti-counterfeiting code is applied to at least one of the plies while it is still wet. In the process shown in Fig. 2, this could be done prior to lamination of the filler and bottom plies 13 and 12, or prior to the addition of the top ply 14. In the preferred embodiment, the code is applied to the bottom ply 12 prior to its being laminated to the filler ply by means of two shower bars 44 and 46.
  • the machine which is represented in Figure 2 may comprise a bottom wire which is 190 inches wide, with the web or fiber plies being 180 inches wide.
  • the anti-counterfeit coding material is applied by shower bars 44 and 46, each of which extends across the width of the fibrous web. Nozzles may be spaced as close as two inches across the entire width of the web with the nozzles in the shower bars 44 and 46 offset with respect to each other so that the printed lines are in fact about one inch apart.
  • the shower bars may be slightly tapered, decreasing in diameter from the input end to maintain the same pressure differential at each of the nozzles across the width of the fibrous web.
  • the nozzles 48 and 50 may be conventional nozzles, for example with a single aperture which will apply a line about 1/32 inch thick on the fibrous web as it is formed on the bottom wire 34. Any desired nozzle configuration can be used, and as mentioned above with respect to Fig. 1, different nozzle configurations may be used to apply lines of different widths for coding purposes.
  • the anti-counterfeit code is color-coded.
  • a suitably colored dye is fed to a holding tank 52 with an adequate amount of water to form a printing medium.
  • the coding medium is a pigment-based dye of any color. Because the fibrous web on which the printing medium is applied is wet, for example 80-90% water, the dye would ordinarily have a tendency to "run" after it is applied.
  • a water retention agent such as carboxymethylcellulose (CMC) is added to the dye solution in tank 52 by means of a hopper 54. The CMC is added to the tank as a solid powder.
  • a suitable coding medium may comprise .l-.3% weight pigment based or direct dye and 4% CMC. The solution is stirred by a conventional mixer 56.
  • a positive displacement or centrifugal pump 58 feeds the coding medium to the shower bar 44 so that it can be dispersed through the nozzles 48 on to the fibrous web formed on the bottom wire 34.
  • Valves may be provided in the various lines to control the flow of the liquid and also for normal maintenance purposes.
  • the system as shown in Figures 2 and 3 is a rudimentary system in that the anti-counterfeiting codes applied by the nozzles 48 and 50 are changed manually, for example by closing selected nozzles. While this is effective from a practical point of view for most purposes, ultimately it is contemplated that a sophisticated computer controlled valving system may be used to open and close preselected nozzles in order to apply automatically a preselected anti- counterfeit pattern. Indeed, the invention contemplates any mechanism for applying an anti-counterfeiting pattern to one or more plys of a multi-ply paper/paperboard laminate during the manufacturing process.

Abstract

Un produit constitué d'une feuille en papier ou en carton présente un motif ou un code anti-falsification appliqué sur une surface de la feuille, dans l'épaisseur. Le code n'est pas visible sur la face de la feuille mais peut être détecté au niveau de l'arête de celle-ci. Le code est appliqué au moyen de techniques classiques au moment où le papier/carton est fabriqué. Des buses ou des dispositifs de pulvérisation (48, 50) sont placés au-dessus d'une des épaisseurs avant que cette dernière soit assemblée avec une épaisseur supplémentaire en vue d'y appliquer un motif d'encre, de poudre métallique ou autre. Ce motif peut varier afin de produire des codes spécifiques pour identification ultérieure. Les codes peuvent être basés sur des couleurs, la largeur des bandes de couleur, leur espacement, leur parcours, etc.
