In 1 is a sheet-processing machine, here a printing press, shown, which consists of one or more printing units, which are used for the following purposes:

• - A sheet to be coated is in a first step in a commissioned work 1 (Printing unit, paint module, o. Ä.) Provided with an imaging adhesive pattern. For example, in a printing unit of an offset printing press on inking and dampening 11 , a printing plate on a plate cylinder 12 , a blanket or blanket cylinder 13 a printed sheet on an impression cylinder 4 printed. Applicators can also be configured as a flexographic printing unit or coating unit (see embodiment in FIG 4 ). The glue can be applied by means of a dosing system 21 over an anilox roller 22 and a transfer roller 23 on a form cylinder 24 be transferred, which carries a high pressure plate for generating the imaging adhesive application.
• - In a second step is in a coating module 2 together with the print sheet a transfer film 5 through a transfer gap 6 guided, with the transfer film 5 in the transfer gap 6 pressed against the sheet. The coating module 2 may correspond to or be integrated into a printing unit, a varnish module, a base unit or a different processing station of a sheet-fed offset printing press. The transfer gap 6 in the coating module 2 is through a press roll 3 and an impression cylinder 4 educated. The press roll 3 can the blanket cylinder 13 an offset printing unit or the forme cylinder of a paint module of a sheet-fed press. The respective impression cylinder 4 is provided accordingly in the corresponding processing station. The press roll 3 is with a press cover 10 or provided as a roller with a corresponding coating. The press fabric 10 or press coating can be carried out, for example, as a plastic coating, comparable to a blanket or blanket. The surface of the press cover 10 or press coating is preferably very smooth. It can also be formed from antiadhesive substances or structures. Furthermore, can directly on the press roller 3 or on the press fabric 10 be provided a limited pressing surface. This may be from the surface of the press fabric 10 be worked out or it can be used as a partial surface of the material of the press fabric 10 additionally on the press roller 3 be attached.
• - Furthermore, the coating module 2 downstream of a so-called calendering be provided when the coated sheet to increase the adhesion of the coating or to increase the smoothness and gloss of the sheet is to be rolled under increased pressure.
• - Furthermore, the coating module 2 downstream of further printing units of a sheet-fed offset printing press can be provided if the coated printing sheet is to be further processed inline for printing with a single- or multi-color image.
• - Furthermore, the coating module 2 downstream of a so-called Lackiermodul be provided if the coated sheet to improve the adhesion of the coating, to protect the coating for accelerated drying and / or to increase the smoothness and gloss of the sheet should be provided with a corresponding coating.

Within the coating module used for the film transfer 2 is a web guide for transfer films 5 shown.

Suitable for processing transfer films 5 are multi-layered. 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 can be, for example, a metallized layer or a gloss layer or a texture layer or a colored layer or a layer containing one or more image patterns.

The transfer foil 5 is on a supply roll 8th the coating module 2 assigned on the side of the sheet feeder. The foil supply roll 8th has a rotary drive 7 on, for the continuous controlled feeding of the transfer film 5 to the coating module 2 is needed.

Furthermore, in the field of Folienzu- and -abführung Leiteinrichtungen 14 , As deflecting or tensioning rollers, pneumatically actuated conducting means, baffles o. Ä. Provided. Thus, the film web of the transfer film 5 always guided without distortion just and in the same voltage against the press roller 3 being held.

The transfer foil 5 This can be done around the press roll 3 be led around (see dashed representation). The foil web 5 can depend on the space available on one side of the coating module 2 be guided in the feeding and discharging strand closely parallel to each other.

The transfer foil 5 may also be substantially tangential to the press roll 3 passing or only wrapping around in a small circumferential angle through the press nip 6 be guided, being from one side of the coating module 2 fed and discharged to the opposite side.

On the outlet side of the printing unit is a film collecting roll 9 represented on which the used sheet material is wound up. Here too is a controllable rotary drive 7 provided.

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 8th to the transfer gap 6 and to the foil collecting roll 9 is controllable so that as far as possible the transfer film 5 is then stopped if no transmission of the imaging layer is to take place:
For reaction-fast timing systems via so-called dancer rollers 18 as exemplified in 1 are drawn, is the control of Drehan drives 7 the film supply rolls 8th or film collecting roll 9 may not be necessary. By means of dancer rolls 18 also the necessary foil tension is 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 partial film webs, the utilization of the transfer film 5 be improved even with zonally different lengths coating areas within a sheet.

Furthermore, it is intended to improve the coating process in the area of the adhesive application and in the region of the film application dryer 16 provided. Thus, in particular by means of UV drying, the imagewise applied adhesive layer by means of a first dryer 16 (Intermediate dryer I) are predried, so that the wear layer of the transfer film 5 better adhered. Furthermore, the adhesive effect of the impressed wear layer on the printed sheet by means of a second dryer 16 (Intermediate dryer II) can be improved by the drying of the adhesive is additionally accelerated.

It are different according to the invention options the aforementioned pictorial Coatings by means of an imaging or metallization layer within work unit or printing units at different positions in a printing press.

Furthermore, an embodiment of an integrated film transfer module for use in a sheet-processing machine is possible. Here, the coating module 2 in the unit of the commissioned work 1 be executed integrated.

A sheet of leading impression cylinder 4 has to transport sheets one or more gripper fields with associated pressure surfaces and a corresponding one to multiple extent. At the impression cylinder 4 is a commissioned work 1 arranged. The impression cylinder 4 is still a Beschich module 2 associated with that of a press roll 3 having, with the impression cylinder 4 a transfer gap 6 forms. The transfer gap 6 is the coating gap of the applicator 1 on the impression cylinder 4 downstream in sheet travel direction.

In this way, an integrated film transfer module is formed, which has two workstations, which are used for the following steps. The printing material is in such a film transfer module in a very advantageous manner by all the necessary cleavage sites in one guided single gripper closure, while on a single impression cylinder 4 rests.

The coating module 2 or integrated film transfer module is essentially suitable for providing a printed sheet before printing with an imaging layer, for example a metallization layer. Within the the coating module 2 or integrated film transfer module receiving sheet-processing machine, such as a sheet-fed offset printing press, the coating module 2 or integrated film transfer module but also be placed at any other point within the machine. This is intended to make it possible for the desired imaging layers, such as metallization layers, to take place both before, as well as after and between the application of ink layers.

With Help of the described device, high quality packaging or advertising media can be effectively processed.

In principle, the arrangement of the coating module allows 2 or the integrated film transfer module, the attachment of a foil pattern of metal or effect foil on a sheet.

Depending on the quality of the printing material, it may be useful or necessary that the substrate is precoated to adapt the surface of the quality requirements of the finishing. For this purpose, the first printing unit or the applicator is on a corresponding printing press 1 and the coating module 2 or the integrated film transfer module one or more paint modules L upstream, which allow applying a primer layer on the sheet.

at the attachment of the film pattern can then be a conventional Glue, similar an offset printing ink can be used. Likewise, a UV adhesive be used. In both cases can be done a predrying of the adhesive layer.

When applying the film pattern from the transfer film 5 this can be warmed by means of appropriate devices to facilitate the solution of the imaging layer or metallization of the film support and so to improve the transmission of the film pattern.

To the application of the film pattern can on the film image a colored Picture to be printed. For this purpose, in the appropriate printing units conventional offset printing inks or so-called foil paints or so called UV inks be used. The drying effect and the adhesion of conventional printing inks on the film screen is relatively poor, as they are on a large scale Dry by so-called knocking. Foil colors are generally oxidative curing Inks that adhere better, but also a relatively long drying time need. UV inks are used to ensure rapid drying Use of a UV dryer to achieve.

ever according to the type of for used to create the color image on the slide image Printing ink can do it for The further treatment of the printing sheet will be necessary, a drying process to join. It is important that the printed sheet is glued by the quasi-glued Foil image has a certain inhomogeneity. It is therefore a good one Dosing of the drying energy necessary.

On effective way, a not yet dried sheet, the a foil image and a color image bears against damage or Pollution protected be applied by applying a paint layer. Here it is possible Dispersion varnishes, so-called primers in combination with dispersion varnishes or to use so-called UV varnishes. By means of such fast drying Lacquer layers leaves a provided with a coating of film image and printed image Protect printed sheets well on the one hand, wherein the adhesive and ink layers under the lacquer layer finish Harden can. On the other hand, the surface becomes of such a sheet thereby additionally refined. The surface gets next a smooth appearance too a very desirable one Gloss effect. This will be additional the surface the film image protected against oxidative influences.

The used paints are transparent or translucent and can be clear or be colored. By means of appropriate color-lacquer combinations, e.g. from conventional printing ink or using a so-called Primers and a UV varnish, the surface of the sheet can also be with Be provided areas of different gloss.

In conjunction with the subsequently applied adhesive for the film image resulting in particularly adherent areas for the metallization. The printed sheet is printed after applying the film image with a multi-color printed image of film color. This applies in particular to printed sheets with a high areal proportion of the film image. The color image dries oxidatively and is not protected. It has a good gloss, but is relatively rough when touched.
• II. On a smooth substrate, a Drucksujet a UV adhesive for the film image is applied, which can be dried between. A film or metallization layer is transferred to the adhesive substrate and, if necessary, inter-dried again. The printed sheet is printed after applying the film image with a single or multi-color printed image of UV ink. This applies to printed sheets with a low to high area proportion of the film image. The color image is finished by means of a UV dryer, but is not protected in the surface. The printing sheet has a good gloss and shows a very good smoothness when touched.
• III. On a smooth substrate a Drucksujet of a conventional adhesive for the film image is applied to a film or metallization layer is transferred. The printed sheet is then printed with a single- or multi-color printed image from conventional offset printing ink (sheet with low to high film content). The color image is optionally dried by means of a dryer. A layer of an invisible primer is applied to the printing sheet for adhesion promotion and then protected by means of a layer of UV varnish. Thereafter, a final drying can take place. The sheet has a very good gloss and is very smooth when touched. The gloss effects of the film areas are slightly dampened and thus subjected to a visually pleasing balancing effect. The printed sheet is immediately dry and processable.
• IV. On a smooth substrate a Drucksujet a UV adhesive for the film image is applied to a film or metallization layer is transferred. The printed sheet is then printed with a single or multi-color printed image of UV ink (sheet with low to high film content).

In the 2 to 5 are various possible combinations of the assignment of coating modules 2 and applicators 1 for a printing machine for carrying out the described production method for packaging means or advertising means shown schematically.

The shown printing presses can provided in all configurations for a feeder AN Film transfer modules or printing units D one or more coating modules L upstream to apply a leveling layer, Primer layer or another kind of pre-coating of To enable printing sheet

In All configurations shown above may precede the print engines a boom AU one or more paint modules L downstream. Leave it a single or multi-layered transparent and thereby clear, brilliant or apply colored topcoat. Between such paint modules L may be arranged an intermediate dryer.

2 basically shows a conventional configuration. A sheet feeder AN of the sheet-fed printing machine is initially a commissioned work 1 and then a coating module 2 downstream. The coating module 2 in turn follow printing units D of the sheet-fed press. A bow boom AU completes the configuration.

through This configuration can therefore be a pictorial coating with metallized Slide on the blank sheet. After that, about this Coating a multicolored printed image are applied.

Likewise, by means of the coating module 2 a full-surface coating with metallized film are produced, which can be overprinted below in the printing units D.

It is indicated that a coating module 2 also the printing units D can be arranged downstream of the sheet delivery AU, wherein the coating module 2 upstream printing unit D as commissioned work 1 can serve.

through This arrangement is, for example, a subsequent lamination or Application of a metallised image coating without overprinting possible. Therefor The color print should be dried before.

3 shows a similar configuration as 3 , Here, the sheet feeder AN downstream of two film transfer modules as integrated coating modules IM. Here, within a work unit, both a coating module 2 as well as an associated commissioned work 1 arranged (see also 2 ). Thus, according to a previously mentioned method example, the image-wise application of two different, next to each other, but possibly cross-over coatings are made. The arrangement of an integrated coating module IM is particularly useful if at least two film transfer modules are to be arranged directly one after the other.

In 4 is shown a flexible variants for a printing press with further improved features of the further processing of signatures. The film transfer module is designed here as an attachment module AM. Such an attachment module AM is preferably designed as a transportable unit and can be placed on a standardized substructure UB of a printing unit D of the printing press. For this purpose coupling mechanisms are necessary, which can be represented in many ways. A substructure UB usually contains a rack in which a sheet transport drum and an impression cylinder 4 are associated with each other. Optionally, on the substructure also a blanket cylinder 13 an offset printing unit or a form cylinder 20 a paint module in each case the impression cylinder 4 be assigned. The blanket cylinder 13 or form cylinder 20 Can in conjunction with the coating module 2 as a press roll 3 be used, with a corresponding stringing 10 is to be attached. Corresponding clamping devices are available on both cylinder types.

In 5 is an advanced version shown. The printing press shown has, after two printing units D connected to the sheet feeder AN, a so-called turning device W. Turning devices W serve to invert a single-sided printed or coated printed sheet during sheet-fed operation of a sheet-fed printing press, so that its previous underside becomes the upper side, which can subsequently be printed or coated.

In the configuration shown close to the turning device W applicator 1 and a coating module 2 at. Thereafter, if necessary, several further printing units D are provided up to the sheet delivery AU.

With Thus, such a printing press can each sheet first of his back printed in one or two colors, then turned, then with a metallized Layer coated by imaging and subsequently again multicolored be printed. An application example of this are greeting cards with jewelery inserts made of metal foil on the picture side.
