Definitions
- the present invention relates to a method of manufacturing a sheet material comprising at least one window, and a security document obtained by said method.
- Patent GB 1 552 853 discloses a bank note comprising a paper layer in which a security thread is incorporated.
- the paper layer has windows on the side revealing the security thread.
- the windows can be made using a laser capable of removing material from the paper layer while leaving the security thread intact.
- the windows may, alternatively, be made mechanically, by cutting or abrasion.
- EP 229 645 discloses a security paper comprising two jets of paper between which is interposed a security thread. Holes are made on at least one of the jets of paper using reliefs on the forming web of this paper jet.
- a sheet of security paper consisting of two layers each having a zone of zero thickness facing one another and a strip of transparent material embedded in the sheet of paper, so that the band of transparent material is facing areas of zero thickness. This gives a transparent window.
- the sheets thus obtained have the disadvantage of having on their faces differences in thickness, in particular thicknesses at the level of the inserted strip, so that as long as the areas of reduced or zero thickness are one large area, the sheet becomes industrially difficult to handle. Indeed, in order to can store or transport the sheets, they are stacked in large quantities, so that the areas of reduced thickness are brought to overlap, which leads to an imbalance of the stack.
- the application WO 2004/001130 describes a method for producing a paper substrate consisting in bringing, in contact with a paper forming web, a security thread, the fabric having reliefs making it possible to produce windows on the substrate through which an edge of the security thread is visible.
- This method is not suitable for incorporating into the paper substrate a safety wire having a relatively large width. Indeed, when incorporating a wide wire, visible defects such as a lack of material may appear on the surface of the paper layer.
- Patent applications EP 0 860 298 and EP 0 625 431 also disclose a process for producing a security paper in which a security thread is incorporated into a first layer of paper according to the "window” technique.
- thread "described in the patent application EP 0 059 056. This layer of paper has on one side a plurality of windows revealing the security thread.
- the first layer is then assembled with a second layer of paper to hide the defect (s).
- US Pat. No. 6,428,051 discloses a security paper comprising a fibrous layer having a window covered by a foil, the window being made by stamping the fibrous layer.
- the dimensions and / or shape of the window depend on the punching tool used, which requires changing the tool if it is desired to form windows of different sizes and / or shapes.
- Application DE 2005 045 566 discloses a process for manufacturing a sheet having two plies of paper, one of which may have an elongated zone of zero thickness in which a safety element is placed and the other may have one or more recesses.
- Application FR 2 891 761 also discloses a method of manufacturing a sheet material comprising two layers of paper having windows made by projecting at least one jet of fluid under pressure after joining the two jets of paper.
- Applications WO 00/39391 and WO 2005/0512249 also disclose processes for forming a sheet of paper made of a single jet on a single round shape.
- An object of the present invention is to provide a method for obtaining a sheet material with a window comprising a security element, preferably quite large, and in particular having no significant extra thickness.
- the subject of the invention is a process for producing a sheet material comprising at least two fibrous juxtaposed juxtaposed with one another, the process comprising the following steps:
- a first paper jet comprising at least one elongated zone of zero thickness, by filtration of an aqueous suspension of fibers on the web of a first round shape or a form,
- a sheet material is thus obtained whose structure comprises, in the superposition region of the elongate zone of zero thickness comprising an at least partially transparent element of the first jet and a recess of the second jet, a transparent window.
- An advantage of the invention is that by inserting an at least partially transparent elongated element between the two still wet jets during the manufacture of the sheet material, the attachment of the at least partially transparent element to the sheet material is enhanced. and the risk of delamination of the structure is greatly diminished.
- the fact that the at least partially transparent element is inserted during the formation of the sheet material and not after its manufacture makes reproduction of the sheet material particularly difficult, while reducing manufacturing costs.
- the fibers comprise cellulose fibers.
- the at least partially transparent element has a width greater than that of the elongated zone of zero thickness of the first jet, so that, when the element is inserted into the less partially transparent within the sheet material, two edges of said at least partially transparent elongated member are inserted between the two fibrous jets.
- the elongated at least partially transparent element has a width 4 to 10 mm greater than that of the elongate zone of zero thickness in which it is arranged.
- Each elongated zone of zero thickness of the first jet has a width preferably between 5 and 50 mm, more preferably between 10 and 25 mm.
- Each at least partially transparent element has a width of preferably between 9 and 60 mm, more preferably between 14 and 35 mm.
- the at least partially transparent element has a thickness of, for example, between 10 and 50 ⁇ m.
- this element has the same thickness as that of the first jet so that the outer surface of the first jet is almost flat and has no significant extra thickness.
- the first jet of the sheet has a thickness of 20 microns, and a continuous strip of the same thickness is disposed in the zone of zero thickness of the first jet.
- the method according to the invention has the advantage that, the sheet material being composed of several jets, it is possible to adapt the thickness of the first jet to the thickness of the transparent element thus making it possible to obtain a flat sheet, whatever the choice of the thickness of the transparent element.
- the at least partially transparent element comprises at least one security means.
- the at least partially transparent element may comprise a device with variable optical effect, interferential, in particular iridescent and / or diffractive, with a liquid crystal, a lens system, a hologram, a magnetic, metallic or crystalline coating, fibers magnetic resonance tracers, detectable X-ray fluorescence tracers, biomarkers, a varnish or an ink, luminescent tracers, in particular fluorescent tracers, photochromic, thermochromic, electroluminescent and / or piezochromic and / or tribometric compounds and / or which change color in contact with one or more predetermined products, or any other similar security means.
- At least one means for securing the at least partially transparent element is located exactly opposite a recess of the second jet. This gives a security sheet comprising at least one observable security means at a window. It is also envisaged that the at least partially transparent element comprises several securing means some of which are located opposite recesses of the second jet, and others are not.
- the at least partially transparent element comprises at least one securing means situated opposite a recess of the second jet, and, at the level of the recess of the second jet, the total thickness of the element at less partially transparent is close to the thickness of the sheet material.
- the at least partially transparent element has a thickness of 20 .mu.m with thicknesses of a thickness of 40 .mu.m in the recesses of the second jet, in which a securing means can be placed.
- An advantage of the security sheet according to the invention is that its structure allows it to have devices which are of greater thickness than the foils generally used in transparent windows, such as chips or tactile devices.
- the foils used usually have a thickness of the order of 5 to 10 microns, while chips or tactile devices may have thicknesses of 30 to 90 microns.
- the at least partially transparent element may be, for example, a patch, or preferably a continuous band.
- the at least partially transparent element may be a patch having the shape of a square 1.5 cm side.
- the at least partially transparent elongated element is a continuous strip and has the same length as the elongate area of zero thickness of the first jet.
- the support of the at least partially transparent element is made of a synthetic material, for example a polyester film.
- the elongate zone of zero thickness and the element at least partially transparent are rectangular in shape, have the same thickness and extend all along the first jet.
- the at least partially transparent element is a continuous strip whose length corresponds to those of the elongated zone of zero thickness of the first jet and the width is 6 mm greater than that of the elongated zone of zero thickness, so that the elongated zone of zero thickness is fully compensated by the continuous band. In this way, it is advantageous to obtain a security sheet whose face corresponding to the first jet is flat.
- the first jet comprises several elongated zones of zero thickness, parallel to each other and at least partially transparent elements located opposite each elongated zone of zero thickness, along the entire surface of the first jet so that the first jet is presented as a succession of fibrous bands and at least partially parallel transparent bands.
- the first jet further comprises at least a lack of at least partial material, located in at least one fibrous region.
- a first structured stream is obtained which is particularly difficult to imitate.
- such a structure makes it possible, thanks to the presence of material shortcomings, to obtain tactile effects allowing recognition of the material to the touch.
- the lack of material is partial, that is to say that, at these gaps, the thickness of the first jet is reduced. If necessary, if the thickness of the first jet is sufficiently reduced in terms of lack of material, the gaps allow to observe the second jet by transparency.
- the lack of material is total, that is to say that, at these gaps, the thickness of the first jet is zero.
- the lack of material makes it possible to directly observe the second jet.
- the gaps may extend over the entire width of the fibrous region in which they are located.
- the material gaps do not extend the full width of the fibrous region in which they are located.
- the gaps may be of different shapes, for example geometric such as circular, triangular, square, rectangular or the like.
- the recess of the second jet has a smaller width or equal to the width of the elongate zone of zero thickness of the first jet.
- the width of each recess of the second jet is at least 5 mm less than the width of the elongate zone of zero thickness of the corresponding first jet.
- the first and / or second stream of the sheet material comprises at least one security element.
- the security elements are placed in the thickest jet, preferably the second jet.
- the first and / or second stream contains a watermark or security thread.
- the second jet comprises security elements located opposite these gaps.
- one of the jets can contain a wide security thread, that is to say whose width is greater than 2 mm, in particular between 2 and 10 mm, of preferably equal to about 3 mm, the zone of incorporation of this wire being covered by the other jet which thus masks the defects that the wire has created.
- the recesses of the second jet may be of different geometric shapes, for example circular, rectangular, square, ovoid, triangular, hexagonal or the like. We can still consider that the recesses have the form of alphanumeric characters, symbols.
- the second jet comprises a plurality of recesses arranged so as to form a code.
- its total thickness may vary between 70 ⁇ m and 2 mm, preferably between 90 and 300 ⁇ m.
- the first and second jets have equal thicknesses.
- the first and second jets have different thicknesses.
- the second jet having the recesses has a thickness greater than 60 microns, to avoid embrittlement of the second jet due to the presence of recesses, this jet must be relatively solid to support the first jet during the manufacture of the sheet material.
- the first throw, consisting of strips of paper continuous can be finer.
- the sheet material has a total thickness of 110 ⁇ m, the first jet being 25 ⁇ m thick and the second jet being 85 ⁇ m thick.
- the second jet of the sheet material comprises at least one multitone watermark located opposite the at least partially transparent element appearing in an elongate zone of zero thickness of the first jet.
- a multiton watermark is composed of light areas, ie areas of thickness less than the thickness of the remainder of the sheet, arranged so as to form a raster pattern.
- Such screened watermarks have been described in patent application EP 1122360.
- This embodiment is particularly advantageous because it makes it possible to increase the durability of a multitone effect watermark.
- multitone watermarks are security elements that are very difficult to reproduce.
- their implementation requires locally reducing the thickness of the paper sheet very importantly, which makes them sensitive to wear and generates the risk that the paper sheet is found. This risk is all the more important as documents comprising security sheets, such as banknotes, are likely to be very frequently handled.
- the elongated area of zero thickness of the first jet is produced by suppressing the filtration of the suspension on at least one zone of the fabric of the first round shape or forming it.
- the suppression of filtration on the first round shape or on forming it is carried out by depositing masking zones on the perimeter of the first round shape or forming it.
- these masking zones are made by means of masks made of an adhesive film, metal, an adhesive or a varnish.
- the fabric of the first round shape or the form is further provided with parts preventing the filtration of the suspension so as to form total gaps in the fibrous material of the first jet.
- the fabric of the first round shape or the form has embossments so as to form partial gaps in the fibrous material of the first jet.
- the elongate zone of zero thickness of the first jet is produced by removal of material by means of a jet of pressurized fluid, in particular a jet of water or water. air, on the first jet still wet, before its assembly with the second jet.
- the recess of the second jet is made by embossing the fabric of the second round shape in relief, which prevents the deposition of fibrous material at the embossments.
- the recesses by fixing on the fabric of the second round shape of parts preventing filtration, for example a piece of metal, in particular an electrotype (that is to say a metal plate, generally bronze), a piece of glue, or a piece of resin.
- the shape of the piece will thus give the shape of the recess. It is envisaged to use pieces of different shapes to make recesses of different shapes.
- the recesses can be made by removal of material by means of a projection of a jet of pressurized fluid, in particular a jet of water, on the second still wet jet, before being assembled with the first jet.
- the first round shape or form, and the second round shape are synchronized so that the at least one recess of the second jet comes opposite the elongate zone of zero thickness.
- the invention also relates to a security document obtained according to the method described above.
- the invention relates to a means of payment such as a bank note or a check, an identity document such as an identity card, a driver's license, a passport page or a visa, or a title such as a title deed or diploma, or any other paper-based document requiring security, or secure packaging or a label.
- the security document is such that the first jet comprises at least two security elements with respect to the least two recesses of the second jet, the two security elements being placed so as to be superimposed when the security document is folded, to form a security or additional information.
- a first security element may be a lenticular network that will cover a second security element consisting of an invisible image, which will be revealed only during the superposition of the two security elements.
- a first security element will be a polarized filter and a second security element will be liquid crystals, forming, for example, an image revealed by the filter.
