Definitions

  • the invention relates to a method for producing a security element for documents of value, banknotes or the like, comprising the steps of: providing a web which contains a plurality of first components of the security element for producing a plurality of the security element, and conveying the web along a route, and Applying a plurality of second components of the security element to the web at the end of the route.
  • the invention further relates to an apparatus for producing a security element for documents of value, bank notes or the like, comprising: a conveyor for conveying a web, which contains a plurality of first components of the security element, along a route and at the end to produce a plurality of the security element the path arranged applicator for applying a plurality of second components of the security element on the web.
  • security elements are increasingly used that consist of several constituents, for example of several layers.
  • An example of such a security element are so-called moire magnifiers, in which microstructures and microlenses are applied one above the other.
  • the microstructures lie on a substrate in a well-defined grid and the microlenses must be formed with respect to raster width and position of this defined grid in a precisely prescribed arrangement to the microstructures.
  • the register between these two components must be very be adhered to exactly. This is technically complex, both when the first and second components are formed on different tracks that must be connected together, as well as when the first and second components are produced by successive printing and / or embossing processes.
  • the application of the second components in exact register position or at least under exact compliance with the desired length ratios to the first components that are already present on the track, done.
  • the DE 42 24 236 A1 discloses, as the closest prior art, an offset rotary press for a color printing system in which a plurality of components of an article to be printed are successively applied in a plurality of printing sections.
  • a paper web is conveyed through the printing sections. Before passing through the printing sections, it is passed over an adjustable draw roll having a biaxially curved lateral surface which variably stretches the web transversely to a web direction to adjust a registration position in the later printing operations.
  • the paper web is selectively supplied with fountain solution in the first pressure stage in order to set a desired expansion behavior transversely to the web longitudinal axis.
  • the WO 2009/083149 A2 provides for the promotion of a film web before applying the second components, the use of a cylindrical Einschwenkwalze before, which is made depending on the adjustment obliquely to the conveying direction of the web. In this way, the web is tilted relative to the axis of a subsequent printing or embossing cylinder so as to maintain the register position between first constituents already present on the web. and to be applied to the printing or embossing cylinder second components, which are defined by the cylinder jacket surface of the corresponding cylinder set.
  • the principle of WO 2009/083149 A2 has proved its worth.
  • security elements which are further improved in terms of their security against counterfeiting, have further increased the requirements for register accuracy between the first and second components.
  • material mixtures are increasingly used for security elements, that is, for example, the combination of a plastic web, which carries the plurality of first components of the security element, with a paper web, which provides the plurality of second components.
  • These material mixtures are difficult to control due to different thermal expansions, heating during conveyance of a web, etc., in terms of production, as far as the registration accuracy when bringing together the different materials is concerned.
  • the invention is therefore based on the object, a method and an apparatus of the type mentioned in such a way that the register accuracy between the existing on the web first components and the application of the second components can be set as accurately as possible.
  • the object is further achieved with a device according to claim 5.
  • a draw roll which has a two-dimensionally curved lateral surface.
  • This draw roll makes it possible to adjust the tension or tension in the middle of the web with respect to the edges, for example to reduce (or preferential) or to increase the tension in the middle of the web.
  • the tension conditions in the web can be adjusted so that the application of the plurality of second components of the security element in register with the first components on the web is done.
  • the web can be further processed, d. H. the end of the track is usually not the end of the machining facility.
  • a biaxial curvature is understood to mean that the lateral surface in each case has a curvature in two sectional planes which are not parallel to one another, ie may be orthogonal in particular.
  • the concept of biaxial curvature is therefore identical in the underlying understanding with the concept of a two-dimensionally curved surface in the mathematical sense.
  • the curvature in each section plane is not limited to satisfying a circular geometry. Rather, arbitrarily shaped lateral surfaces also fall under the term biaxial or two-dimensional curvature.
  • the biaxially curved lateral surface of the draw roll causes the draw roll is no longer a pure circular cylinder in the mathematical sense.
  • a cylindrical surface is known then obtained by moving a closed trajectory (the so-called generator) along a straight line.
  • Conventional rolls have as a generator a circle which is displaced along a straight line, they are circular cylinders.
  • the draw roll also has as a generator in preferred embodiments a circle which is now displaced not along a straight line, but along a curved trajectory.
  • the circle as a generator is responsible for a uniaxial curvature, the curved trajectory, along which the circle is moved to generate the lateral surface, causes a further axis of curvature.
  • the approach of the present invention when conveying the web in the processing machine, allows the tension on the web to be adjusted to compensate for distortions across the width of the web. As a result, distortions that would lead to the production of rejects can be avoided when applying the second constituents or, more generally, in the concerted execution of processing steps on the web.
  • the processing steps may include, for example, the generation of a desired overall motif in which a first print layer is applied to the web in a first processing step. This can be the provision of the web to be conveyed or in the device a processing device located before the start of the route.
  • the print layer can be, for example, a motif grid for a moiré magnifier, a modulo mapper or a tilted image with or without magnification effect.
  • the application of the second components may be, for example, the application of a microlens layer with a microlens grid, which has to stand in a predetermined relationship to the first motif grid in order to achieve a desired overall motif.
  • the draw roll according to the invention makes it possible to compensate for distortions across the width of the web, ie transversely to the conveying direction. Disturbances of one of the two motif grids and disturbances of the overall motive are avoided.
  • the order in which the first and second components are applied can be reversed.
  • the solution of the invention achieves a particular economics benefit in that wider webs can be used which would otherwise be required for conventional manufacturing apparatus / methods due to distortions caused by, for example, the conventional Conveying devices and / or caused by inhomogeneities in the material of the web or could be made worse, would not be suitable.
  • the device can at the beginning of the route a processing device, for. B. a printing unit, which generates the first components on the web.
  • the incoming film already contains the first constituents. Then the film passes through a printing unit, in which a UV-curable medium (embossing lacquer) is applied. Subsequently, the web is conveyed on to produce the second components. In this case, the elongation of the incoming film must be corrected so that the second components harmonize as desired with the first components in terms of position and dimension. It is possible to use a UV-curable medium or a thermoplastic medium or a thermoplastically deformable film.
  • a UV-curable medium embssing lacquer
  • the processing steps in particular the production of the first and second components, can take place both on one and the same side of the web, as well as on different sides.
  • a positive side effect of the device according to the invention or of the method according to the invention is that the requirement for the film quality with regard to stretching at different tension or different voltages is markedly reduced. It is no longer absolutely necessary to use films which have a very homogeneous expansion behavior, but can even out a material-related inhomogeneous expansion in the case of film material which exhibits a comparatively inhomogeneous expansion behavior by suitably setting the draw roll.
  • a particularly preferred design is a roller which has the shape of a curved circular cylinder. It is therefore a circular cylinder in and of itself cylindrical, the term "circular cylinder” being understood here in the mathematical sense. He describes a cylinder, which is obtained by moving a circle, which is the generator in the mathematical sense, along an axis. By bending this axis, the draw roll provided according to the invention with a two-dimensionally curved lateral surface is obtained.
  • the bending of the circular cylindrical roller that is, the deflection of the axis of the roller adjustable.
  • the curved roller is additionally rotatably mounted at both ends such that the plane of the maximum bending can be inclined relative to the plane of the continuous film web (pivotable roller). It is possible here, the direction, in which the maximum bend shows change. At the same time, it is expedient to make the outside of the web to be conveyed end points of the roller as adjustable as this WO 2009/083149 A2 for a conventional roller already describes. The disclosure of this document is therefore fully incorporated in this regard.
  • the application of the plurality of second components of the security element is accomplished by providing and connecting an additional web containing the plurality of second components to the web.
  • the invention is particularly advantageous in cases where the additional web is made of a different material than the web. For example, different strains of the material mix plastic web / paper web can be well balanced.
  • an applicator is provided which has a laminating unit, and a feeder feeds the additional sheet to the laminating unit.
  • the plurality of second constituents are applied by means of a printing or embossing process.
  • the device then has as an applicator on a printing or embossing.
  • the plurality of second components is applied at the end of the route through a printing or embossing cylinder, through which the web is guided.
  • a further variant for the roller with a two-dimensionally curved lateral surface is a so-called S-roll: it contains in its interior a plurality of elements with the aid of which the extent of the sheathing at the respective point can be influenced. It has the advantage that the shape of the roller can be made very flexible, in particular can be more complicated than a simple bend.
  • a curved circular cylinder whose bending and optionally also pivoting position are adjustable
  • a cylinder which has a convex or concave shape in cross-section, ie is barrel-shaped or spindle-shaped.
  • the curvature of the lateral surface is not changeable, but one can use a cylinder whose basic shape is adapted to normal conditions with respect to the stretching of the web.
  • Alternative lateral surfaces are represented by cones in the middle or else considerably more complicated shapes, which can be realized by milling or turning and which influence the expansion of the film or the conveyed medium in the desired manner.
  • rollers during operation d. H. not deformed continuously during rotation. The risk of material fatigue is lower, or it can simpler materials for the roller can be used.
  • the roller used has a sheath which influences the adhesion or friction to the medium used. Local adhesion or friction characteristics varying over the length of the roll can also affect the elongation of the conveyed medium in the desired sense. With a positive result, a grooving of a plastic coating of a draw roll was tested.
  • An alternative to producing a variable adhesion profile is to use a locally applicable electrostatic charge on the roller.
  • the registration between first and second components is continuously monitored during operation and the position of the draw roller is adjusted accordingly within the scope of a regulation.
  • the measuring device is downstream of the draw roll.
  • the draw roll can be adjusted in the sense of a regulation to set the position of the first components predetermined. Unlike when measuring after applying the second constituents, it is still possible to react here if there is a misplacement of the first constituents, since an adjustment of the draw roll on the entire web path acts until the second constituents are applied. Measuring between the draw roll and the end of the stretch, d. H. Thus, at the point where the application of the second constituents begins, there is the advantage of avoiding the production of rejects, and nevertheless a relatively simple control can be carried out whose manipulated variable is the adjustment of the draw roll.
  • the invention comprises a position detector device, which is arranged on the track and is designed to determine a position of the first components.
  • the device comprises a corresponding control device which controls the adjustable draw roller, in particular in the form of a control.
  • measuring devices are expediently located on all webs.
  • the microstructure is required to be 0.5% smaller than the microlens grid across and along the film transport direction the microlens grid. So z. B. according to the embossing the microlens grid by 0.5% larger than the microimage grid.
  • the microlenses are produced (preferably by embossing in transparent lacquer).
  • microlens and microimage raster geometry can be determined from the deviation between the enlarged nominal image and the real visible enlarged moiré image, which raster width difference and which angle between microlens and microstructure is set. After comparing the actual and setpoint, the draw roller can be readjusted.
  • Very high magnification factors can also be generated by means of microlenses and microimages and a suitable grid arrangement of the two structures relative to one another. It can z.
  • moiré images may be produced which appear to be above or below the film plane by more than 1 cm and have a size of several millimeters.
  • Moire images of this kind are very well suited for security elements because of their size and the striking depth or height effect.
  • a security element there is always very limited space available on a banknote.
  • a well-perceived motif with several millimeters in size should be positioned centrally in the middle of the thread.
  • a moiré image with approx. 10 mm can be positioned so that it appears centrally on the patch with a vertical viewing angle.
  • moire motifs as large as this, care must be taken that the enlarged motifs appear on all value documents of similar size and position in the film element. This is very difficult to accomplish in the production because, with a lateral shift of the microlens to the microstructure grid of only one screen pitch (typically 10 ⁇ m to 50 ⁇ m), the magnified motif already shifts laterally by a distance resulting from microstructure grid size times magnification factor and therefore in the range of several millimeters.
  • a positional accuracy of a large moiré image can only be achieved if the microimages are controlled with a position accuracy of a few micrometers below the microlenses.
  • the magnification factor here is 300. If this enlarged image may deviate from its nominal position on the film by ⁇ 2 mm, this means that the micro image under the microlens must comply with a lateral positional tolerance of 6.7 ⁇ m. Preferably, therefore, the enlarged moiré image itself is used.
  • the size and the position of the moiré image are recorded by means of a camera and image evaluation, and with this information the draw roller in the feed of the web is adjusted so that the enlarged moiré image is at the desired position on the film.
  • the controlled system moves only in the range of 1 .mu.m to 50 .mu.m.
  • the absolute positioning accuracy is not set, but the relative aspect ratios are adjusted to achieve the proper magnification.
  • the concept of position detection of the first components thus also includes the position detection of the combination of first and second components and in particular the evaluation of a moiré image with regard to magnification and / or distortion.
  • a control variable for the retraction position or angle of the draw roll is determined from the position detection.
  • the moire motifs can be quite different in type and size for different applications.
  • the evaluation of different size and shape variable motifs in terms of size and location is for image analysis always difficult. Therefore, adaptive systems are preferably first trained on the respective motif.
  • control motifs are provided on the web and optionally on the additional web, which are particularly preferably evaluated on the film edges and / or on the film width in size and optionally position of the camera detection and evaluation tool and thus the respectively necessary readjustment the film stretching is initiated.
  • a simple control motif a stripe design of alternating light and dark stripes in and perpendicular to the film running direction is mentioned. The strips ideally have the same or a slightly different periodicity compared to the microlens grid. This stripe design allows tracing distortions to be detected by detecting the moire magnified stripes, as well as tilting between microlens and microstructure patterns by skewing the magnified stripes.
  • control motif could be arranged at several positions across the width of the film (eg left edge, right edge and in the middle). It could be arranged continuously over the film longitudinal direction or as a repetitive motif along the film. It could thus provide the information to correct both the film stretching and a tilt of the film.
  • Such a control motif would be the same for all Moire Magnifier films. The advantage here is that the image acquisition system only needs to be trained on the recognition and evaluation of this one control motif.
  • microlens rasters may also be useful to use different microlens rasters in the control motifs of the image motif. It is apparent from the prior art that the sensitivity of the enlarged motifs to angle errors between microlens and microimage grid with increasing magnification increases. Therefore, it may make sense to choose a microlens and microimage grid with very small feature size and high magnification as a control. The sensitivity of the control motif to raster width changes and angular errors between microlens and microstructure is then very high and deviations from the setpoints can be detected very accurately.
