The present invention relates to machines for printing securities with protection, and the machine includes a device for feeding paper sheets, the feeder in a printing unit, wannah sheets.

Known embedding as a protective element optically different or similar images in the form of a film, for example, credit card or securities, in particular banknote, with the aim to prevent or complicate the fake last. Such images, which is often different optical and containing either a hologram or Kinegram have the ability to change appearance depending on the angle of their consideration.

Application of the above images can be done in various ways. As example can serve as a technical solution is described in European patent A-0441596 (MOLINS), which disclosed a method and apparatus for applying such image on the banknote in the cold. In this device, the paper sheets after selective deposition of a glutinous paint on certain parts, which correspond to the areas of the sealing banknotes, and after passing through the drying ultraviolet radiation enters the device applied to such image on the tape coiled on the area between the unwinding coil installed in the first tape, and winding a coil that is installed in the second cassette. The tape moves simultaneously with p is also located on the ribbon, applied to specific areas, thus causing the device comprises at least one rolling roller, cooperating with the printing cylinder, the paper moves between the roller and the cylinder. The ribbon is located between two coils that are placed in the sector rolling roller, and moves along a generatrix of this roller and perpendicular to the path of movement of the paper.

This type of installation is equipped with a tool that provides excellent accuracy when applying different optical images and the selection of the necessary provisions on securities.

Such facilities are provided, in principle, only a single type of printing protective element, they are expensive and therefore not suitable for printing limited circulation or circulation of securities, which do not require high quality printing.

In the case when you want to put on valuable paper two protective element different methods, it is necessary to have two installations, each of which corresponds to the type and method of applying a protective element. Also in the case when it is necessary to apply different methods protective drawings on the limited series, requires settings for each the printing paper protection which can easily be converted in relation to one or another known method, a protective seal.

The machine according to the invention differs in that the printing device is made modular to adapt to different types of security print and that it consists of elements that are common to all different types of print, and includes the device screen printing with a stencil cylinder communicating with the pressure cylinder, and located below the drying device/activation behind the cylinder transportation in the direction of the second pressure roller, intended for interaction with at least one printing device of the protective element.

The advantage of the machine according to the invention is that by appropriate selection of certain permanent members forming this machine, you can easily bring it in line with different types of printing with protection, without having each time to install, designed for a specific type of printing with protection. Therefore, using the basic installation, it becomes relatively easy while limiting capital expenditures to add modules that interact with this setup, and get the print protection svu the invention, the above-mentioned basic elements of the printing machine is complemented by the installation for applying images as stamps or strips, moreover, the above images are placed on the ribbon, moving between the unwinding and winding coils simultaneously with the movement of the paper and between the second pressure cylinder and the rolling roller interacting with pressure cylinder.

Depending on the operating procedure and the type of damage marks or streaks in the sections of screen printing on paper, moving between the pressure roller and stencil cylinder, pre-applied paint, which is a component adhesive or self adhesive. The application is made selectively to relevant areas of the paper that will later be placed protective of the brand or band.

In the case of the adhesive component, the second component is located directly on the brand or protective strip, in this case, the heated roller for rolling the activation of both components. In the case where an adhesive substance consists of only one component, protective stamps or strips are applied to this adhesive directly to cold rolling with a roller.

According to another variant of the invention, the protective seal is at least one rolling roller, which is been at least one pair of coils, among which is moving along the tape, i.e., in this case, the tape is moved perpendicular to the paper feed direction periodically after each application. In this case, each roller may contain multiple pairs of coils providing in a single pass of the paper application of protective elements in several rows of its leaves. It is also possible to use the second rolling platen, such as described in the aforementioned European patent A-0625466. In this setting, the screen printing section is used either for applying the first component of the adhesive, and the second component is located on the stamps or strips, and the application is made in hot or screen printer uses a one-component adhesive, and brand or strip with a protective pattern is applied in a cold state.

According to another variant embodiment of the invention, similar to the variant in which the tape is moved simultaneously with the movement of the paper caused a hot brand or band (hence, the sections of screen printing is applied on the adhesive paper is not the first component) partially printed or not printed, and the printing microstrip above elements to overprint stamps or strips with tape, moving simultaneously with the movement of paper, and tape the cylinder, provided with a plate with a relief image. With the passage of the paper with a protective element between the second pressure cylinder and the cassette cylinder is printing microstructure corrugating brand or band. After this deformation, the second below the cassette cylinder stencil cylinder is applied, selectively, on the received picture varnish, fixing the microstructure obtained by embossing the paper. After lacquering possible it is dried in the drying device before entering the control device of the printing quality.

Finally, in another embodiment of the invention, in which still applies basic machine, screen printing section is made with the possibility of applying the coating layer for printing shirring.

In this case, the second printing cylinder in contact, similarly to the above case with cassette cylinder containing the relief printing plate, which after contact with the previously applied coating in the screen printing section forms an image by shirring the specified coating. In this setting, the obtained microstructure is also applied lacquer on the and varnish in the drying device, and thus is fixed printed microstructure. After that, the paper is fed into the device control print quality.

More in detail the invention is illustrated with the accompanying drawings.

In Fig. 1 schematically shows a side view of the installation in which the protective image is printed on the tape, moves simultaneously with the movement of paper.

In Fig.2 schematically shows also a side view of the installation in which the protective pattern is drawn from multiple tapes, moving perpendicular to the direction of movement of the paper.

Fig.3 is a variant embodiment of the invention according to Fig.1.

In Fig. 4 schematically shows a side view of the installation in which the sheet is applied coating, which is then sealed by crimping.

In the drawings used in the same position, indicating the elements that form the very basis of the installation. Therefore, in the description and in the designation of the common elements are the same figures.

The apparatus comprises a device 1 power supply sheets of securities, in particular banknotes. These leaves, which can be already partially printed or not printed, are served one after the other through the feeding roller 2 to the first clamping cylinder 3, interacting with the screen cylinder 4. Relitivaly, which device preferably ultraviolet radiation. Then the transport cylinder 6 leaves served on the second pressure cylinder 7. After that - depending on the implementation of the other elements provide printing protective figure, explain below. After sealing the sheets are grasped transporting device 8 with clips. The sheets pass through the device 9 controls the print quality and then forwarded to the drives 10, 11, 12 for the sealed sheets.

The following describes an embodiment of the installation shown in Fig.1.

Compared with the base installation this installation includes a device 13 for applying stamps or strips with protective image on paper sheets moving between the second pressure cylinder 7 and the rolling platen 14. Below is a brief description of the device 13, which is similar to the device described in European patent A-411596. Protective image in the form of stamps or strips are located on the ribbon 15, stretched between the two coils 16 and 17, and the coil 16 - unwinding reel 17 - winding. For placing marks or stripes on the place the tape passes through various transmission devices before santros accuracy for damage images and their placement on the paper, located between the cylinder 7 and the rolling platen 14. In principle, the tape is moved in step mode, however, depending on the destination, and, in particular, in the case when using the band, it is effective to apply the setting in which the tape 15 is fed simultaneously with the paper.

According to a variant embodiment of the invention, the screen printing section 3, 4 is made to apply to specified sections of the paper located between the pressure cylinder 3 and screen 4 cylinder, the first component of the adhesive substance in the form of paint, the paper then moves past the device 5 drying or activation of the specified component, and is supplied to the pressure cylinder 7. According to this first variant of the invention, the second component of the adhesive is on the stamps or strips, and during the application of the rolling roller 14 is heated and provides adhesion of the brand or band to the securities.

According to another variant embodiment of the invention, the screen printing section 3, 4 allows you to put in specified areas of the paper adhesive contained in the active state of the device 5, and with the passage of the paper between the pressure cylinder 7 and the rolling roller is who can be called a cassette. Obviously, in that case, when the paper contains several columns arranged in the direction of its motion, the cartridge will be placed in parallel strips, which allows for one pass to apply a mark or stripe on all the columns of the paper sheets.

The following describes a variant implementation of the invention in Fig.3, are quite similar to the variant in Fig.2 with some exceptions. Indeed, the cassette 13 can contain a tape with a partially printed or completely printed marks or streaks. After their application, in hot or cold, as described above, cassette cylinder 18 in contact with the second pressure cylinder 7 through the plate 18a with a relief image makes it possible to obtain a microstructure on the stamp or strip by passing the paper between the printing cylinder 18 and the pressure cylinder 7. Obviously, in this case, the material used for the manufacture marks or stripes, has a structure that ensures printing with shirring. Then sealed so the paper is passed between the screen cylinder 19 and the pressure cylinder 7 for coating the obtained microstructure with the aim of fixing it. When capturing paper transportrulepredicate device.

The advantage of this setup is that it is possible to use, in particular for relatively small series, the tape 15 with a partially printed or not printed marks or stripes and replace the plate 18a for the sealing of a series of securities with different motifs.

Is depicted in Fig.2 installation for applying protective drawings includes two rolling roller 21, 22, provided with a fixed on them coils. These coils provide the unwinding of the tape to the generatrix of the rolling roller 21 or 22, and the passage of the paper sheet between the knurled roller and the pressure cylinder 7 brand or band is fixed on the paper sheet in the space provided. In principle, each roller 21, 22 contains several pairs of coils, ensuring the passage of the tapes with labels or strips, provided with a protective figure, for application during the passage of grades or bands on multiple series of securities, printed on paper sheets. For more information and details about rolling rollers 21, 22, you can refer to patent application EP-A-0625466.

Obviously, in this case, the tape is moved perpendicular to the direction of movement of the paper. And here is the section of the tra is the first substance is applied to specified areas of the paper, and marks or stripes on the tape contain the second component, which is activated by the application of a rolling roller 21 or 22 by heating, or by using a stencil cylinder 4 put a layer of adhesive, and applying labels or strips is in a cold state.

Finally, in the screen printing section 3, 4 of the installation of Fig.4 is applied to the coating layer on the sample space of the sheet moving between the pressure cylinder 3 and screen 4 cylinder. This layer is dried with UV drying unit 5. Cassette cylinder 23 includes a plate 23a with relief microstructure, which allows you to print the shirring on pre-printed paper sheets to the floor. The second screen cylinder 24 provides the lacquer on the pre-formed microstructure with the aim of fixing it. As described above, the drying unit 25 allows you to dry the varnish before leaf fall in the device control print quality.
