Description

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.

It is known to produce metallic layers on printed sheets by means of a film transfer process. So is in the EP 0 569 520 B1 a printing material and a printing apparatus using this material are described. In this case, a sheet-processing machine is shown, which has a feeder and a boom, wherein printing units and a coating module are arranged between the two units. In at least one of the printing 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. In the printing unit following the coating module with a counter-pressure cylinder and a press roller, a film guide is provided. This is designed in such a way that a film strip or a transfer film is guided through the transfer nip of the coating module between the impression cylinder and the press roll from a film supply roll. The film strip is rewound on the outlet side after leaving the coating module. 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.

When printing sheets are transported through the printing unit, 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.

After further transporting the printing 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. The used in this way 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.

The solution to this problem results in a method according to the features of claim 1 and in a device according to the features of claim 3.

Advantageously, the transfer film is described with protected readable information or provided within the attachment to the substrate.

In this case, so-called biocodes are advantageously used in the adhesive applied to the printing sheet, which removes the imaging layer from the transfer film.

Furthermore, 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.

Furthermore, the 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.

In this case, the image-forming layer on the transfer film can be transparent, semi-transparent, opaque or opaque. In this case, the information applied is then made directly readable or readable by means of different types of electronic detection options.
In this context, 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. In combination with the above-mentioned method, it is thus also possible to use different types of film side by side.
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.
Advantageously, 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.

To improve the gloss effect, 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.

Advantageously, it is also possible to provide a plurality of coating modules behind one another within a sheet-processing machine. Thus, the application of different imaging coatings or metallization layers within a subject can take place one after the other. In this case, it is possible to transmit the imaging layers next to one another using a single adhesive pattern with all the image pattern elements. It is also possible 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.

In the following the invention is illustrated in more detail with reference to figures.

• Ein zu beschichtender Druckbogen wird in einem ersten Arbeitschritt mit einem bildgebenden Klebstoffmuster versehen. Der Auftrag des Klebers erfolgt im einer als Auftragwerk 1 konfigurierten Vorrichtung, z.B. einem konventionellen Druckwerk einer Offsetdruckmaschine über dort vorhandene Farb- und Feuchtwerke 11, eine Druckplatte auf einem Plattenzylinder 12, einen Drucktuch- oder Gummizylinder 13 und einen Gegendruckzylinder 4.
• Danach wird in einem zweiten Schritt gemeinsam mit einem Druckbogen eine Transferfolie 5 durch einen Transferspalt 6 geführt, wobei die Transferfolie 5 im Transferspalt 6 gegen den Druckbogen gepresst wird. Hierzu wird ein Beschichtungsmodul 2 verwendet, das einem Druckwerk oder einem Lackmodul oder einer Basiseinheit oder einer andersartigen Verarbeitungsstation einer Bogenoffsetdruckmaschine entsprechen kann.
• Der Transferspalt 6 im Beschichtungsmodul 2 wird durch eine Presswalze 3 und einen Gegendruckzylinder 4 gebildet.. Hierbei kann die Presswalze 3 einem Drucktuchzylinder und der Gegendruckzylinder 4 einem Gegendruckzylinder eines an sich bekannten Offsetdruckwerkes entsprechen.
  Weiterhin kann die Presswalze 3 einem Formzylinder und der Gegendruckzylinder 4 einem Gegendruckzylinder eines Lackmodules einer Bogendruckmaschine entsprechen.
• Weiterhin kann das Beschichtungsmodul 2 gemeinsam mit dem Auftragwerk 1 in einem Druckwerk angeordnet sein, wobei das Auftragwerk 1 Farb-, Feuchtwerk, Platten- und Gummizylinder nutzt. Das Beschichtungsmodul 2 kann am gleichen Druckzylinder dieses Druckwerks dem Druckspalt des Kleberauftrages nachgeordnet sein.

FIG. 1 shows a sheet-processing machine, here a printing press, which consists of at least two printing units. The two printing units are used for the following purposes:

• A sheet to be coated is provided in a first step with an adhesive imaging pattern. The application of the adhesive takes place in a device configured as an applicator 1, for example, a conventional printing unit of an offset printing press on there existing inking and dampening 11, a printing plate on a plate cylinder 12, a blanket or blanket cylinder 13 and a counter-pressure cylinder. 4
• Thereafter, in a second step, together with a printing sheet, a transfer film 5 is guided through a transfer nip 6, wherein the transfer film 5 is pressed in the transfer nip 6 against the printing sheet. For this purpose, a coating module 2 is used, which a printing unit or a paint module or a base unit or a different kind of processing station Sheetfed offset press may correspond.
• The transfer nip 6 in the coating module 2 is formed by a press roll 3 and an impression cylinder 4. In this case, the press roll 3 can correspond to a blanket cylinder and the impression cylinder 4 to an impression cylinder of a known offset printing unit.
  Furthermore, the press roller 3 a form cylinder and the impression cylinder 4 correspond to a counter-pressure cylinder of a paint module of a sheet-fed press.
• Furthermore, the coating module 2 may be arranged together with the applicator 1 in a printing unit, the applicator 1 color, dampening, plate and blanket cylinder uses. The coating module 2 may be arranged downstream of the printing gap of the adhesive application on the same printing cylinder of this printing unit.

Within the coating module 2 used for the film transfer, a web guide for transfer films 5 is shown.
For processing in question 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.
Furthermore, in the field of Folienzu- and -abführung Leiteinrichtungen 14, such as deflection or tensioning rollers, pneumatically actuated conducting means, baffles o. Ä. Provided. Thus, 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 Verschutzungen whose protective function is maintained at the same time completely.

In this case, 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. In a further embodiment, 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. For this purpose, 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.

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.

For the transfer process of the imaging eg wear layer of the transfer sheet 5 on the sheet in the transfer nip 6 between the press roll 3 and the impression cylinder 4 is essential that the surface of the press roll 3 so the blanket cylinder or forme cylinder is equipped by means of a compressible, damping element.
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. Furthermore, combined fabrics made of a hard blanket and a soft pad can be used.
Furthermore, 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.

To improve the efficiency of the coating process, it is provided that 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 :
For this purpose, 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. Timing systems via so-called dancer rollers 18, as they are shown by way of example in Figure 1, the control of the rotary actuators 7 of the film supply rolls 8 and film collection roller 9 may not be required. By means of the dancer rollers 18, the necessary film tension is also maintained.

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 Teilfolienbahnen lesser width. Thus, with appropriate control by means of the device or devices for timing the film feed each of the sub-film webs, the utilization of the transfer film 5 can be improved even in zonally different lengths coating areas within a sheet. For this purpose, 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.

Furthermore, it is intended to improve the coating process in the area of the adhesive application and in the. Provide area of the film order dryer 16. Thus, in particular by means of UV drying, 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. Furthermore, 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.

Finally, the quality of the coating by means of an inspection or Monitoring device 17 are checked after the foil application. For this purpose, 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.

According to FIG. 2, 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. In this case, the heat can be introduced into the film web 5 via deflecting rollers 19, tempering rollers 20 or radiators 21. Furthermore, the film guide 14 can be acted upon with heated blowing air.
