Definitions

  • the invention relates to a fibrous sheet, in particular of paper, used in particular for manufacturing security documents such as banknotes, checks, transport tickets, entrance tickets to cultural or sporting events, identity documents. , etc ...
  • paper means any sheet obtained by the wet process using a suspension of natural cellulose fibers and / or of numerical or organic fibers other than cellulose, possibly synthetic, which may contain various fillers and various additives commonly used in stationery.
  • This sheet is more particularly obtained by papermaking and consists of at least two jets; it can include at least one zone of reduced opacity.
  • a sheet comprising an area of zero thickness, called transparent window, having an area of at least 0.2 cm 2 in which a wide plastic strip appears.
  • the strip is transparent or translucent and is at least 15 mm wide. This window cannot be reproduced by photocopy, it protects the document obtained from photocopying.
  • This strip is inserted between two layers of paper during the production of the sheet. It is therefore positioned over an entire length, or an entire width, or an entire height of the sheet, but it does not occupy the entire surface of the sheet.
  • This strip creates an extra thickness in the sheet.
  • the parts comprising the strip are superimposed and create a raised area in the stack. This can cause problems when processing sheets, such as when cutting or printing, the sheets may slip out of the stack.
  • problems can also be encountered due to the unevenness of the sheets; similarly when they are stored in a bundle.
  • a person skilled in the art can position shims between the sheets. It can also cross the stacks of a few sheets to alternate the extra thicknesses of the stacks. This therefore requires additional handling of the sheets.
  • the sheets are produced according to the following process: the strip is glued after manufacture of the sheet and of the transparent window, while at the same time embossing by embossing to incorporate this strip.
  • a disadvantage of such a sheet is that the strip is on the surface and not inside the support; it can therefore be easily counterfeited by sticking a strip of transparent plastic on a paper from which a window has been cut. In addition, the strip can be easily damaged.
  • a sheet is described consisting of two layers of paper and a transparent film of the same size as the sheet, the sheet does not have a transparent window. These various elements are assembled by lamination using an adhesive.
  • the substrate has visible indices in transmitted light.
  • the substrate occupies the entire surface of the sheet to overcome the problems associated with the (non) flatness of the sheet, however such a sheet has several drawbacks.
  • One drawback is that it can be easily counterfeited because it is easy to stick a plastic film between two sheets of paper.
  • This watermark can be a so-called dark watermark.
  • a watermark is obtained during the manufacture of the fibrous sheet by means of round shapes comprising the imprint engraved in the hollow, of the watermark to be reproduced.
  • Such a watermark therefore has extra thicknesses.
  • finished security sheets like banknotes they are 20 ⁇ m and can reach 35 ⁇ m for the darkest watermarks.
  • Watermarks can also be made on a flat table machine by pressing a watermarking roller on the wet spray, however they cannot be obtained with as great a contrast as on a round shape or with such thick thicknesses. Indeed, the watermark is obtained with the watermarking roller by a simple displacement of the fibers and not by accumulation of fibers. Unlike the round shape technique, you cannot therefore obtain watermarks with significant shades of gray.
  • dark watermarks because they have a richer aesthetic effect and because the extra thicknesses are detected by touch by the blind to recognize banknotes, for example.
  • Another advantage of making a dark watermark is that it makes it possible to obtain an image, a pattern having a good definition (sharpness) for the sheets made up of several jets.
  • a person skilled in the art positions shims between the sheets. Such compensation is necessary to allow the correct processing of the sheets, but requires additional and tedious work which hinders rapid processing of the sheets, particularly at the time of printing.
  • the object of the invention is therefore to provide a security sheet having good flatness while having good protection against counterfeiting.
  • the object of the invention is achieved if a watermark, hollow or embossed, and at least one strip is combined, in a configuration ensuring flatness on the sheet.
  • strip we mean a strip made of a single piece or a strip made of an assembly, a stack or a juxtaposition, of strips.
  • the strip consists of a material insoluble in water and more particularly it is made of plastic. Preferably it is transparent or translucent.
  • the strip has a width greater than 15 mm and less than the largest dimension of the sheet.
  • the strip and the watermark have substantially the same thickness.
  • the sheet is made up of at least two jets and is formed by papermaking on a round shape, the strip being positioned under one of the outer jets.
  • a sheet made up of at least two jets because it allows, among other things, to protect the tape and to avoid an easy reproduction of the document by the counterfeiters who could for example stick a false tape on a sheet.
  • a sheet formed on a round shape is preferred because, although it could be formed on a flat table paper machine (Foudrinier machine), the watermarks on these flat tables are formed with a watermark roller which gives little relief or depth to the watermark and therefore less suitable for the invention.
  • the sheet can also be formed on a paper machine combining a flat table and a round shape, the watermark being formed on the round shape.
  • the strip may have a heat-sealable or water-sealable varnish on the surface to improve its resistance in the sheet and to avoid its separation from the sheet.
  • the sheet is characterized in that the watermark is a clear watermark made on the internal or external face of the external jet and that the strip is positioned on the internal face of the external jet under the watermark and in look of it.
  • the sheet is characterized in that the watermark is a dark watermark produced on the internal or external face of the external jet and that the strip is positioned on the internal face of said external jet, the strip being placed in the part of the sheet without watermark.
  • the raised part of the watermark has a thickness E1 substantially equal to the thickness E of the strip.
  • Figure 1 is a sectional and exploded view of a sheet according to the invention, having a clear watermark.
  • Figure 2 is a sectional and exploded view of another embodiment of a sheet according to the invention, having a clear watermark.
  • Figure 3 is a top view of the sheet shown in Figure 1.
  • Figure 4 is a sectional and exploded view of a sheet according to the invention, having a dark watermark.
  • Figure 5 is a top view of a sheet according to the invention comprising an area of zero thickness.
  • FIG. 6 is a top view of a sheet according to the invention comprising an area of zero thickness.
  • Figure 7 is a schematic view of a device for manufacturing a sheet according to the invention.
  • FIG 1 there is shown a sheet 1 according to the invention.
  • This sheet comprises a first jet 2 of paper and a second jet 3 of paper.
  • the jets can be produced in a known manner on a paper machine with a flat table (Fourdrinier machine) or with a double round shape.
  • the clear watermark is made on shape 9 which includes the imprint of the watermark in relief, the strip 4 being introduced between the two wet jets under the watermark, then the jets and the strip are assembled by the lifting roller 11.
  • the first jet 2 has an internal face 2i and an external face 2e.
  • internal face is meant the face which is inside the finished sheet, that is to say when the jets 2 and 3 are joined.
  • external face is meant the face which is outside the finished sheet.
  • the second jet 3 has an internal face 3i and an external face 3e.
  • the first jet 2 has a clear watermark 5 which is produced on the internal face 2i. Due to the presence of this watermark, the thickness of the jet 2 has recessed parts which therefore when the jet is stacked, cause extra thicknesses opposite the zones which do not have the watermark and therefore the stacks of paper are difficult to handle. and have all the disadvantages which have been mentioned above.
  • the sheet according to the invention comprises a strip 4 which is placed under the watermark 5. This strip has a thickness E which is substantially equal to the difference in thickness formed by the watermark.
  • the strip 4 is positioned on the internal face 2i of the external jet 2 under the watermark 5 and facing it. This therefore compensates for the difference in thickness.
  • the sheet is characterized in that the watermark 5 is a clear watermark made on the external face 2e of the external jet 2 and that the strip 4 is positioned under the watermark and facing that -this on the other side of the jet, as shown in the example in Figure 2.
  • a double round shape is used as previously but the clear watermark is produced on the form 10 which includes the imprint of the watermark in relief, the strip being introduced between the two wet jets, on the other side of the watermark, then the jets and the strip are assembled by the roller 11.
  • the sheet is characterized in that the watermark 5 is a dark watermark made on the external face 2e of the external jet 2 and that the strip 4 is positioned on the other side of the jet and in part A of the sheet not including the watermark.
  • a double round shape paper machine is used as before; the dark watermark is produced on the form 10 which has the imprint of the hollow watermark, the strip being introduced between the two wet jets, in an area not comprising the watermark, then the jets and the strip are assembled by the roller 11 .
  • the sheet is characterized in that the watermark 5 is a dark watermark made on the internal face 2i of the external jet 2 and that the strip is positioned under this jet and in the part of the sheet not including the watermark, as shown in FIG. 4.
  • the relief part 12 of the watermark has a thickness E 1 substantially equal to the thickness E of the strip 4.
  • a paper machine with a double round shape is used as in the previous case but the dark watermark is produced on shape 9 which has the imprint of the hollow watermark.
  • the strip occupies almost the entire space between the watermark and the edge of the sheet.
  • the strip has a width equivalent to that of the watermark and the watermark is produced so as to cover the entire strip.
  • the sheet comprises at least one zone of reduced opacity in which the strip appears.
  • the zone of reduced opacity can be produced by transparency of an area of the sheet, on one or more jets if the sheet is a multijet.
  • the transparency can be obtained by the use of a resin or a transparent oil, in a solvent or aqueous medium, as described for example in patent EP-B-91341 or using a transparent wax or paraffin. hot.
  • the zone of reduced opacity may be a watermark, provided that it does not harm the object of the invention, namely the flatness of the sheet. In the case where this zone is a clear watermark, the zone of reduced opacity and the watermark combined with the strip may be confused.
  • the zone of reduced opacity can be achieved by locally reducing the thickness of the sheet, in particular during the formation of the jets.
  • the zone of reduced opacity can be produced according to patent application EP-A-549384, namely on a paper machine using flexible pieces placed on the watermark means of the machine which locally reduce the drainage of the water during the formation of the sheet.
  • This zone of reduced opacity can also be produced according to the method of French patent application FR 9410242.
  • This process makes it possible to produce a zone of reduced opacity which can contain in the plane of the sheet a circle with an area of at least 0.4 cm 2 thanks to an embossed canvas, the canvas being of reduced thickness in the zones embossed.
  • This process makes it possible to obtain zones of reduced opacity having uniform lightness and opacities, this zone is therefore of substantially uniform opacity.
  • the sheet is characterized in that at least one zone of reduced opacity is of zero thickness.
  • the zone of reduced thickness of zero thickness (also called “transparent window”) is capable of containing in the plane of the sheet at least one circle of at least 1 cm in diameter.
  • the sheet is characterized by the fact that it has zones of zero thickness throughout its thickness and that these zones are opposite one another and that the part of the strip appearing in these zones is at least in transparent part.
  • Such a sheet with an area of zero thickness can be produced according to patent application WO-A-9509274, in particular on a paper machine with double round shape, the shapes being synchronized so that the respective openings of the jets are opposite , the window is made by embossing on each of the round shapes which prevents the deposition of fibers.
  • the strip may have patterns and in particular, the sheet is characterized in that the strip has patterns appearing at least in reflected light in at least one zone of reduced opacity.
  • These patterns can be applied, beforehand, to the strip by a printing means such as offset, rotogravure, serigraphy or inkjet printing, using a conventional ink or security i.e. fluorescent, phosphorescent, magnetic, photochromic, thermochrome, piezochrome, iridescent, etc ...
  • a white background Before printing the patterns, a white background can be applied to make the patterns stand out better. You can also apply a background after printing the patterns to reduce the visibility of solid patterns.
  • This background may be discontinuous. If the strip is transparent, the transparent zones of the discontinuous background are positioned in the zone of reduced opacity, in particular if the zone of reduced opacity is of zero thickness to avoid reproduction by photocopying.
  • FIG 5 there is shown another embodiment of the sheet according to the invention which is such that on the one hand the patterns 6 of the strip appearing in transmitted light, in the sheet outside the opacity zone reduced and, on the other hand the patterns 7 of the strip appearing at least in reflected light in the reduced opacity zone 8, are associated by their representations and / or their positions.
  • the sheet is characterized by the fact that the patterns of the strip appearing in transmitted light, in the sheet outside the zone of reduced opacity and / or the patterns of the strip appearing at least in reflected light in the area of reduced opacity are associated with the watermark by their representations and / or their positions.
  • the patterns can be associated with each other and / or with the watermark by their representation if, for example, they represent the same design, the size or the colors being able to be different.
  • the patterns can be associated with each other and / or with the watermark by their positioning if, for example, they are positioned at given distances or in relation to specific elements contained in the drawings.
  • the patterns can be associated with each other and / or with the watermark by their representation and their positioning if, for example the drawing or drawings representing them complement each other visually or by the theme they evoke.
  • the sheet is characterized in that the zone of reduced opacity and the watermark combined with the strip are associated by their representations and / or their positions.
  • An example is shown in Figure 6, the reduced opacity zone 8 being of zero thickness.
  • the invention also relates to the use of a sheet as previously described for making banknotes. Finally, the invention also relates to a stack of homogeneous thickness of sheets or banknotes, positioned in the same direction, constituted by the sheets or notes previously described.
  • Pulp is made from cellulose fibers, fillers and a wet strength agent.
  • strips of transparent and biaxially oriented polypropylene are introduced on the machine between the jets marked on the machine in the running direction and in the cross direction, outside the watermark zones.
  • the jets and the bands are assembled by the lifting roller 11.
  • the sheet is dried and optionally surfaced to give it the characteristics necessary for its use. A generally flat sheet is obtained.
  • a coarse pre-cut is made of the reels into sheets and then the sheets are cut with a paper cutter in a format suitable for printing banknotes.
  • pulp is prepared from cellulose fibers, mineral fillers and a wet strength agent.
  • the paper pulp is sent and two jets weighing 40 g / m 2 each are formed, these jets are marked on the machine in the running direction and in the cross direction.
  • a zone of reduced opacity is formed which is of zero thickness (transparent window) on each of the jets, thanks to the embossings present on each round shape, each zone being identified in the forward and cross direction.
  • the shapes are synchronized according to a mechanical coupling in order to obtain opposite the zones of zero thickness of each jet and thus to form a window in the sheet, as described in patent application WO-A-9509274.
  • a dark watermark is formed on the jet of form 9; this watermark is 4 cm wide. Strips of transparent and bioriented polypropylene, about 10 cm wide, are introduced between the jets, outside the watermark zones, and so as to make them appear in the transparent windows.
  • the printed patterns and the watermark are geometrically similar.
  • the jets and the bands are assembled by the lifting roller.
  • the sheet is dried and optionally surfaced to give it the characteristics necessary for its use. A generally flat sheet is obtained.
  • a coarse pre-cut is made of the reels into sheets and then the sheets are cut with a paper cutter in a format suitable for printing banknotes. No problem of sliding of the sheets made according to the invention is observed, during this cutting or during the printing. These sheets thus printed are then cut to the format of the desired bank note. These notes form bundles of uniform thickness and therefore do not pose a storage problem.
  • the transparent window in which appears on the one hand a pattern printed on the strip and on the other hand a transparent unprinted zone of the strip, is not reproduced faithfully because the transparent part cannot not be.
