Definitions

  • the invention relates to a device for transferring imaging layers from a carrier film to printing sheet according to the preamble of patent claim 1.
  • a printing material and a printing apparatus using this material are described.
  • a sheet-processing machine which has a feeder and a boom, wherein printing units and a coating module are arranged between the two units.
  • an adhesive pattern is applied by means of the planographic printing process. This adhesive pattern is applied in a cold printing process and has a specific imaging subject.
  • a film guide is provided in the printing unit following the coating module with a counter-pressure cylinder and a press roller.
  • the transfer film has a carrier layer on which imaging layers such as metallic layers, for example of aluminum, can be applied. Between the metallic layer and the carrier film, a separating layer is provided, which ensures that the metallic layer can be removed from the carrier layer.
  • each sheet is given an adhesive pattern. Thereafter, the sheet is passed through the coating module, being brought by means of the press roller on the impression cylinder resting sheet with the film material in combination. In this case, the downwardly lying metallic layer enters into a close connection with the areas provided with adhesive on the printed sheet.
  • the metallic layer adheres only in the area provided with the adhesive pattern.
  • the carrier film is thus removed from the metallic layer in the region of the adhesive pattern.
  • transfer film is wound up again.
  • the print sheet is laid out in the coated state. It is known to use such coating modules, for example in printing units of printing presses. A disadvantage of the known devices is that they can not be used flexibly.
  • the object of the invention is therefore to provide a device by means of which the transfer of an imaging layer, e.g. a metallization layer can be done on a sheet safely, economically and accurately, the device should be manageable for an extended range of applications.
  • an imaging layer e.g. a metallization layer
  • the transfer film is described with protected readable information or provided within the attachment to the substrate.
  • biocodes are advantageously used in the adhesive applied to the printing sheet, which removes the imaging layer from the transfer film.
  • an article security device can advantageously be secured by means of securing elements mounted on the transfer film, such as e.g. Holograms are made.
  • attachment of a security device or personalized information can advantageously be applied to the transfer film and transferred to the printed sheet by means of the transfer film.
  • the image-forming layer on the transfer film can be transparent, semi-transparent, opaque or opaque.
  • the information applied is then made directly readable or readable by means of different types of electronic detection options.
  • a transponder technology with an actively or passively responsive to a radiofrequency radiation circuit visible or invisible attached.
  • the device can also be advantageously used in order to improve the use of the film by dividing the transfer film into one or more partial film webs of lesser width.
  • To ensure the efficiency of the coating process can be provided to control the film feed such that the transfer film is then stopped when no transmission of the imaging or metallization takes place.
  • a control of the transfer film can be carried out such that, when passing through a cylinder channel receiving the grippers of the sheet-guiding impression cylinder, the film feed is stopped, wherein the press roll then passes in a sliding manner under the transfer film.
  • the image-forming layer can be applied by means of so-called UV negative-pressure ink.
  • the UV negative pressure ink is applied by means of the printing unit for the adhesive in a corresponding manner via an offset set plate.
  • a plurality of coating modules behind one another within a sheet-processing machine.
  • the application of different imaging coatings or metallization layers within a subject can take place one after the other.
  • a first adhesive pattern be provided in a first coating module with a first image-forming coating or metallization and superimposed in the following another, apply the first enclosing adhesive pattern and provided with a different imaging coating or metallization.
  • transfer sheets 5 are constructed in multiple layers. They have a carrier layer on which an imaging layer is applied by means of a release layer.
  • the separating layer serves to facilitate lifting of the imaging layer from the carrier layer.
  • the image-forming layer may be, for example, a metallized layer or a glossy layer or a texture layer or a colored layer or a layer containing one or more image patterns.
  • the film supply roll 8 is assigned to the coating module 2 on the sheet feed side.
  • the film supply roll 8 has a rotary drive 7.
  • the rotary drive 7 is required for the continuous controlled feeding of the transfer film 5 to the coating module 2 and is therefore controllable.
  • the film web of the transfer film 5 can always be performed flat without distortion and held in the same voltage against the press roller 3.
  • the guide devices 14 may also contain aids for introducing the transfer film 5. In this case, automatic retraction aids for the film web of the transfer film 5 can be used. In this way, the film feed is simplified in the area surrounding the coating module 2 Verschutzept whose protective function is maintained at the same time completely.
  • the transfer film 5 can be guided around the press roll 3, wherein the transfer film 5 can be fed and discharged in an advantageous manner from one side of the coating module 2 to the press nip 6.
  • the transfer film 5 can also be fed in and out substantially tangentially on the press roll 3 or wrap it around the press nip 6 only in a small circumferential angle.
  • the transfer film 5 is supplied from one side of the coating module 2 and discharged to the opposite side of the coating module 2.
  • a film collection roller 9 On the downstream side of the printing unit, a film collection roller 9 is shown. On the film collecting roll 9, the used film material is wound up again. Again, a rotary drive 7 is provided for the optimized production, which is controllable. In essence, the transfer film 5 could also be moved by the rotary drive 7 on the discharge side and kept taut on the inlet side by means of a brake.
  • the press roll 3 is therefore provided with a press fabric 10 or as a roll with a corresponding coating.
  • the press fabric 10 or press coating for example, as a plastic coating, comparable to a Blanket or blanket, be executed.
  • the surface of the press fabric 10 or press coating is preferably very smooth. It can also be formed from antiadhesive substances or structures. Here, for example, a relatively hard structure in the form of very fine spherical caps comes into question.
  • a press fabric 10 is held on the press roll 3 in a cylinder channel on jigs.
  • the press fabric 10 may be equipped to improve the transmission properties in the transfer nip 6 with a targeted elasticity. This may optionally act in a compressible intermediate layer. This compressibility is preferably similar or less than in conventional blankets or blankets, which can also be used at this point.
  • the mentioned compressibility can be produced by means of a conventional compressible printing blanket.
  • combined fabrics made of a hard blanket and a soft pad can be used.
  • a limited pressing surface can be provided directly on the press roll 3 or on the press fabric 10. This can be worked out of the surface of the press fabric 10 or it can be additionally attached as a partial surface of the material of the press fabric 10 on the press roller 3.
  • the film advance of the transfer film 5 from the film supply roll 8 to the transfer nip 6 and the film collection roll 9 is controllable so that as far as possible the transfer film 5 is stopped when no transfer of the imaging layer should take place :
  • a control of the transfer film 5 can be made such that the film feed is stopped when passing through a gripper of the sheet-guiding counter-pressure cylinder 4 receiving cylinder channel.
  • the grippers hold the printed sheet on the impression cylinder 4.
  • the press roll 3 has a corresponding cylinder channel, in which the fabric is held. In the region of the corresponding cylinder channels, there is no pressing of the transfer film 5 between the press roll 3 (blanket cylinder) and the impression cylinder 4.
  • the press roll 3 then slides under the transfer film 5 while the transfer film 5 is tensioned freely between the press roll 3 and impression cylinder 4 is. This state continues until at the so-called pressure beginning of the cylinder channel ends and the transfer film 5 is again clamped between the press roller 3 and the impression cylinder 4, including a sheet. Then, the transfer sheet 5 is further transported.
  • the timing of the film feed can begin or suspend slightly earlier than pretend the channel edges of the cylinder channel according to a necessary acceleration or braking of the film supply roll 8 or film collecting 9. For fast reactions.
  • a further improvement of the film utilization of the type described results from the fact that the transfer film 5 is divided into one or more Operafolienbahnen lesser width.
  • the utilization of the transfer film 5 can be improved even in zonally different lengths coating areas within a sheet.
  • each partial film web is conveyed only exactly in the area where the imaging surface layer is to be applied. In the areas not to be coated, each partial film web can be stopped independently of the other partial film webs, whereby no unnecessary film consumption arises.
  • the imagewise applied adhesive layer can be predried by means of a first dryer 16 (intermediate dryer I) so that the wear layer of the transfer film 5 adheres better.
  • the adhesive effect of the applied wear layer on the printed sheet can be improved by the action of a second dryer 16 (intermediate dryer II) by additionally accelerating the drying of the adhesive.
  • the quality of the coating by means of an inspection or Monitoring device 17 are checked after the foil application.
  • the inspection device 17 is directed to a sheet-guiding surface of the coating module 2 after the transfer nip 6 and optionally sealed off from the dryer 16 or on a sheet-guiding surface of the coating module 2 downstream further sheet leading module.
  • the pre-applied coated printing sheet can thus be checked for completeness and quality of the coating. As poorly recognized printed sheets can be marked or rejected in a sorter as waste.
  • the coating module can be provided with means for heating or conditioning the transfer film in order to improve the layer transfer and the coating result.
  • the heat can be introduced into the film web 5 via deflecting rollers 19, tempering rollers 20 or radiators 21.
  • the film guide 14 can be acted upon with heated blowing air.
  • a data storage device as a passive or active storage element can be attached to the film roll.
  • an RFID transponder may contain information about the length of the film roll as well as adjustment parameters for processing.
  • the current remaining stock of a film roll can again be currently written to the RFID transponder.
  • the review of the roll stock before the start of a new print job can be adjusted.
  • This technique ensures that the correct film web at the application site is always used across the format width, or that in general the correct film web has been mounted in the machine for this job.
