Description

[0001] The invention relates to a multi-application module, a multi-application device and a working method for a multi-application device.

[0002] Substrates can be decorated using digital printing processes with subsequent application of transfer layers in special printing and / or finishing devices. Using inkjet printing, it is possible, on the one hand, to apply an adhesive directly to the substrate in a specially designed printing device. On the other hand, it is also possible to apply an adhesive to the transfer product using inkjet printing in another, also specially designed printing device. In both cases, the transfer product and the substrate are then brought together so that the transfer layers of the transfer product to be applied adhere to the substrate via the adhesive and are subsequently detached from a carrier layer of the transfer product.

[0003] For example, WO 2016 / 150681 A1 discloses a method and an application device for applying a transfer layer of a film to a substrate, wherein a radically curable adhesive is applied to a portion of the transfer layer using an inkjet print head. CN 107 933 080 A discloses a device comprising a cold transfer unit and inkjet print heads.

[0004] A particular disadvantage of the above-mentioned processes is that they require specially designed printing and / or finishing devices for applying the adhesive to the transfer product or to the substrate, or that, to date, only specially designed printing and / or finishing devices are known. For example, depending on whether the adhesive is to be printed onto the substrate or the transfer product, a special machine is required, which increases the mechanical complexity and thus the costs, and also results in a lack of flexibility. This is particularly true because the print quality and / or intended use differ between these two cases.For example, printing directly onto the substrate usually results in the adhesive running and / or being absorbed into the substrate, whereas printing onto the transfer product usually involves additional effort in aligning the transfer product to the substrate.

[0005] The invention is based on the object of providing an improved printing and / or finishing device and an improved (working) method for a printing and / or finishing device, by means of which the disadvantages of the prior art are preferably avoided.

[0006] This object is achieved by a multi-application module for printing a substrate or a transfer product according to patent claim 1.

[0007] This object is further achieved by a multi-application device comprising a multi-application module according to the invention according to one of claims 1 to 10, and a cold transfer unit, wherein the cold transfer unit comprises a pressure roller and a counter-pressure roller.

[0008] This object is also achieved by a (working) method for a multi-application device according to one of claims 11 to 17, wherein according to a first variant i) a substrate is guided along a multifunctional element to a printing gap formed between a printing unit and the multifunctional element for printing the substrate and is then guided to a counter-pressure roller and a pressure roller with which a transfer product is pressed onto the substrate, or that according to a second variant ii) the transfer product is guided along the multifunctional element to the printing gap formed between the printing unit and the multifunctional element for printing the transfer product and is then guided to the counter-pressure roller and the pressure roller with which the transfer product is pressed onto the substrate, and that the substrate and / or the transfer product in variants i) and ii) are each guided in an opposite running direction, in particular in the multi-application module.

[0009] By means of the multi-application module according to the invention, the multi-application device according to the invention and the

[0010] The (working) method for a multi-application device ensures that both variants, namely printing on the substrate and printing on the transfer product, can be carried out using one and the same machine, in particular one and the same printing and / or finishing device. This enables flexible use, by means of which the advantages of printing, in particular in the form of an adhesive, on the substrate or the transfer product can be specifically utilized without having to provide two machines for this purpose. Thus, simply by using the multi-application module according to the invention in a finishing machine, it is possible to print on the substrate or on the transfer product, since the multi-application module according to the invention enables printing in two opposite running directions.In other words, both variants are possible by changing the substrate and transfer product paths on one machine using the multi-application module according to the invention. This reduces the machine effort and thus the costs, while simultaneously increasing the flexibility to select the appropriate variant for the respective application and thus achieve an optimal result.

[0011] "Mounted for rotation in two opposite directions" is understood here to mean that the first multifunctional roller and / or the at least one second multifunctional roller can rotate in two directions, i.e., clockwise and counterclockwise. The first multifunctional roller and / or the at least one second multifunctional roller has, in particular, an axis that allows both directions of rotation. Preferably, the axis of the first multifunctional roller and / or the at least one second multifunctional roller is the longitudinal axis of the first multifunctional roller and / or the at least one second multifunctional roller and runs transversely to the feed direction of the substrate and the transfer product.

[0012] "Two running directions" here means that the running directions or feed directions of the substrate and the transfer product are different or opposite, particularly different or opposite in the area of ​​the printing gap. Furthermore, depending on whether the substrate or the transfer product is being guided, it is advantageous for the substrate to be printed and the transfer product to be printed to move in opposite directions. For example, it is possible for the substrate to be printed with one running direction from left to right and the transfer product to be printed with one running direction from right to left, or vice versa.

[0013] The term "transfer product" refers to a transfer film comprising a carrier layer and a transfer layer, wherein the transfer layer is removable from the carrier layer.

[0014] Furthermore, it is expedient if the transfer film comprises a release layer, in particular which is arranged between the carrier layer and the, in particular removable, transfer layer.

[0015] The release layer preferably has a layer thickness between 0.01 µm and 10 µm, preferably between 0.1 µm and 5 µm, and / or consists of waxes, polyethylene (PE), polypropylene (PP), cellulose derivatives and / or poly(organo)siloxanes.

[0016] The transfer layer is preferably formed as a single-layer or multi-layered structure. It is thus possible for the transfer layer to comprise a decorative layer, in particular wherein the decorative layer comprises one or more layers selected from the group consisting of: opaque layers, translucent layers, transparent layers, colored lacquer layers, replication lacquer layers, metal layers, and metal oxide layers.

[0017] It is possible that the transfer layer has a layer thickness of between 1 µm and 10 µm.

[0018] It is also possible for the carrier layer to comprise materials, individually or in combination, selected from: polyester, polyolefin, polyvinyl, polyimide (PI), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), and in particular to have a layer thickness between 5 µm and 50 µm, preferably between 7 µm and 23 µm.

[0019] Advantageously, the "substrate" is a single-layer or multi-layer plastic substrate, a single-layer or multi-layer paper substrate, or even a multi-layer hybrid substrate comprising one or more paper layers and one or more plastic layers. It is also possible for the substrate to comprise cotton fibers, wood fibers, cellulose fibers, textile fibers, and / or plastic fibers.

[0020] It is also conceivable to provide a multi-application module for printing a substrate or a transfer product, wherein the multi-application module comprises a printing unit and a multi-function element, wherein a printing gap is formed between the printing unit and the multi-function element, and wherein the multi-function element has a first multi-function roller and / or at least one second multi-function roller and / or a printing table, and wherein the multi-application module enables two running directions, and enables printing of the substrate in a first running direction of the two running directions and printing of the transfer product in a second running direction of the two running directions, in particular wherein the first and second running directions are opposite.

[0021] In other words, it is possible to provide a multi-application module for printing a substrate or a transfer product, wherein the multi-application module comprises a printing unit and a multi-function element, wherein a printing gap is formed between the printing unit and the multi-function element, wherein the multi-function element is designed to guide the substrate or the transfer product, so that in the printing gap when the substrate is guided on the multi-function element, in particular in a first running direction, the substrate is printed and that in the printing gap when the transfer product is guided on the multi-function element, in particular in a second running direction opposite to the first running direction, the transfer product is printed.

[0022] This makes it possible for the substrate or the transfer product to be printed depending on the two running directions.

[0023] Furthermore, it is also conceivable to provide a (working) method for a multi-application device, in particular according to one of claims 22 to 33, wherein the multi-application device comprises a multi-application module with a printing unit and a multifunctional element and a cold transfer unit with a pressure roller and a

[0024] comprises a counter-pressure roller, wherein a printing nip is formed between the printing unit and the multifunctional element, wherein according to a first variant i) a substrate is guided along the multifunctional element to the printing nip for printing the substrate and is further guided to the counter-pressure roller and the pressure roller, with which a transfer product is pressed onto the substrate, or wherein according to a second variant ii) the transfer product is guided along the multifunctional element to the printing nip for printing the transfer product and is further guided to the counter-pressure roller and pressure roller, with which the transfer product is pressed onto the substrate, and that the substrate and / or the transfer product in variants i) and ii) are each guided in an opposite running direction, in particular in the multi-application module.

[0025] Furthermore, it is also conceivable to provide a (working) method for a multi-application device, wherein the multi-application device comprises a multi-application module with a printing unit and a multifunctional element and a cold transfer unit with a pressure roller and a counter-pressure roller, wherein a printing nip is formed between the printing unit and the multifunctional element, wherein according to a third variant iii) a substrate is guided along the multifunctional element to the printing nip for printing the substrate and is further guided to the counter-pressure roller and the pressure roller. The third variant iii) is advantageously characterized in that no transfer product is clamped and the pressure roller is open. In other words, this means that in this working method according to the third variant iii), only one substrate is printed.

[0026] It is expedient if the multi-application module and / or the multi-application device and / or the working method for a multi-application device serve to apply a transfer layer of a transfer product to a substrate. Furthermore, it is expedient if the multi-application module and / or the multi-application device and / or the working method for a multi-application device serve to print a substrate.

[0027] Furthermore, it is preferred if the multi-application device is a multi-application device for applying a transfer layer of a transfer product to a substrate. It is also advantageous if the multi-application device performs this by means of a (working) method according to one of claims 34 to 46.

[0028] Furthermore, it is preferably possible for the multi-application device to be a multi-application device for printing on a substrate.

[0029] It is also conceivable that the (working) method for a multi-application device is a method or working procedure, in particular for operating a multi-application device or for performing three (operating) variants or work cycles of a multi-application device. Preferably, the three (operating) variants or work cycles are the first variant i), the second variant ii), and the third variant iii).

[0030] Furthermore, the use of a multi-application module according to the invention for printing a substrate or for printing a transfer product, in particular with a UV-curable ink, is conceivable.

[0031] It is therefore advantageous if the printing of the substrate or transfer product involves printing with a UV-curable ink, especially where the UV-curable ink serves as an adhesive. The UV-curable ink can be transparent, translucent, or opaque. The UV-curable ink can be colorless or colored with dyes and / or pigments. The colors of the dyes and / or pigments can be visible in visible light and / or under UV light and / or IR light.

[0032] Furthermore, a printing system is conceivable, wherein the printing system comprises a multi-application module, preferably according to the invention, more preferably for printing a substrate or a transfer product, with a printing unit and a multifunctional element, in particular wherein a printing gap is formed between the printing unit and the multifunctional element, and wherein the printing system further comprises the substrate and / or the transfer product. It is also advantageous if the printing unit is designed such that it can print along two running directions in the printing gap.

[0033] Furthermore, a system is conceivable, wherein the system comprises a multi-application module, preferably according to the invention, more preferably for printing a substrate or a transfer product, with a printing unit and a multifunctional element, in particular wherein a printing gap is formed between the printing unit and the multifunctional element, wherein the system further comprises a cold transfer unit with a pressure roller and a counterpressure roller, and wherein the system still further comprises the transfer product and / or the substrate. Here, too, it is advantageous if the printing unit is designed such that it can print along two running directions in the printing gap.

[0034] Advantageously, the substrate or the transfer product is or will be guided in the printing system or in the system, as already explained above and further explained below. In In other words, all features disclosed in connection with the multi-application module, the multi-application device or the (working) method for a multi-application device are also transferable to the printing system and / or the system and are therefore also deemed to be disclosed for the printing system and / or the system.

[0035] Further advantageous embodiments of the invention are described in the subclaims.

[0036] Preferably, the printing gap is arranged between the peripheral edge of the multifunctional element and the printing unit. In particular, it is provided that the printing gap is formed between the printing unit and the surface opposite the printing unit. The surface opposite the printing unit can be, for example, the first multifunctional roller and / or the printing table and / or the at least one second multifunctional roller. Preferably, it is also possible for the printing gap to be formed between the printing unit and the surface of the substrate and / or the transfer product.In particular, it is provided that the substrate and / or the transfer product is clamped along two second multifunctional rollers and / or along the first multifunctional roller and a second multifunctional roller on the side opposite the printing unit, so that the substrate and / or the transfer product forms the surface opposite the printing unit.

[0037] It is thus expedient if the printing gap, in particular the distance between the substrate or the transfer product guided on the peripheral edge of the multifunctional element and the printing unit, has a size between 0.1 mm and 5 mm, preferably between 0.5 mm and 3 mm, in particular between 0.5 mm and 1 mm.

[0038] It is also preferred that ink be ejected from the printing unit perpendicularly, i.e., perpendicular to the surface of the multifunctional element, in particular to the surface of the first multifunctional roller and / or to the flat printing surface and / or to the flat surface of the printing table. For this purpose, it is particularly advantageous if the surface of the printing unit with the "nozzles" is arranged parallel or substantially parallel to the surface of the multifunctional element opposite the printing unit or the adjacent tangent to the surface of the multifunctional element, in particular to the first multifunctional roller and / or the at least one second multifunctional roller and / or the printing table.

[0039] This surface opposite the printing unit is preferably arranged horizontally and, in particular, is designed to be as flat as possible, i.e., it has little to no curvature in one or more directions. In the case of the surface of the first multifunction roller, the surface should be cylindrically curved in only one direction, and this curvature should be as small as possible, for example by ensuring the diameter of the first multifunction roller is as large as possible. Any undesired distortions of the print image on a curved surface can be at least partially compensated for by digital or electronic pre-distortion or pre-compensation of the digital print data, so that the print image on the curved surface is as minimally distorted as possible.

[0040] Furthermore, it is expedient if the multi-application module also has two winding rollers for receiving the transfer product.

[0041] It is possible, for example, that a first of the two winding rollers is driven clockwise and / or a second of the two winding rollers is driven counterclockwise.

[0042] However, it is also possible for a first of the two winding rollers and a second of the two winding rollers to be driven clockwise or counterclockwise.

[0043] In other words, it is also possible for the two winding rollers to have the same or opposite directions of rotation.

[0044] Thus, it is expedient for the transfer product to be unwound from a first of two winding rollers and wound onto a second of two winding rollers, in particular wherein the first of the two winding rollers and the second of the two winding rollers have the same or opposite directions of rotation. It is further expedient for the transfer product to be unwound from a first of two winding rollers and wound onto a second of two winding rollers, in particular wherein the first of the two winding rollers is driven counterclockwise and / or the second of the two winding rollers is driven clockwise.

[0045] Thus, in variants i) and ii) it is possible that the first of the two winding rollers is driven or rotated clockwise and / or the second of the two winding rollers is driven or rotated counterclockwise.

[0046] The position and drive direction of the winding rollers are preferably also dependent on the running direction of the substrate and / or the transfer product. Assuming that the running direction of the substrate and / or the transfer product in the printing nip is opposite to the running direction of the transfer product, assuming that the transfer layer must be printed on the transfer product, assuming that this is wound on the inside of the transfer product roll and must then point towards the printing unit in the printing nip, there are many variables that influence the direction of rotation of the first winding roller, in particular the unwinding roller. The direction of rotation of the second winding roller, in particular the take-up roller, is not dependent on this and can basically rotate in either direction, fulfilling the function of winding up the carrier layer in both cases.

[0047] In this way, in particular the transfer product is provided and after application of at least a partial area of ​​the transfer layer to the substrate, the carrier layer separated from the transfer layer is wound up again.

[0048] It is possible for the multi-application module to further comprise a tensioning system for tensioning the transfer product, wherein the tensioning system comprises one or more of the following elements, selected individually or in combination: dancer roller, controlled dancer roller, measuring roller, friction shaft. This achieves transport of the transfer product under tension.

[0049] Advantageously, it is provided that the first multifunctional roller in combination with a second multifunctional roller and / or the first multifunctional roller in combination with two second multifunctional rollers and / or two second multifunctional rollers are arranged such that the substrate or the transfer product can be guided over the first multifunctional roller and / or the at least one second multifunctional roller and thereby forms a flat printing surface, in particular can be guided such that the substrate and / or the transfer product forms a flat printing surface.

[0050] It is also possible that the flat printing surface is arranged perpendicular to the printing unit and / or forms a surface with a size between 250 mm 2< and 1000000 mm 2< , preferably between 1000 mm 2< and 200000 mm 2<.

[0051] It is also advantageous that the printing table is arranged in such a way that the substrate or the transfer product can be guided over the printing table.

[0052] This creates a flat printing surface, which enables precise and high-quality printing results.

[0053] The printing table preferably forms a flat surface, in particular between 250 mm 2 and 1,000,000 mm 2 , preferably between 1,000 mm 2 and 200,000 mm 2 . It is also possible for the printing table to have a length in the feed direction of the substrate and / or the transfer product between 5 mm and 500 mm, in particular between 10 mm and 100 mm, and / or a width transverse to the feed direction of the substrate and / or the transfer product between 50 mm and 2,000 mm, in particular between 100 mm and 1,000 mm.

[0054] Furthermore, it is preferred if the printing table is arranged perpendicular to the printing unit. It is also possible for the printing table or the flat printing surface to be arranged such that the ink is ejected from the printing unit perpendicular to the printing table or the flat printing surface.

[0055] It is also expedient if the distance between the printing unit and the printing table and / or the flat printing surface, in particular the flat printing surface of the substrate or the transfer product, is between 0.1 mm and 5 mm, preferably between 0.5 mm and 3 mm.

[0056] It is also possible for the printing table to have air outlets to create an air cushion, especially an air cushion between the printing table and the substrate or transfer product. This enables a particularly smooth movement of the substrate or transfer product across the table, further increasing printing accuracy and print quality. This also prevents scratching of the back of the substrate.

[0057] It is also advantageous if a UV-curable ink can be printed or is printed using the printing unit.

[0058] Furthermore, it is expedient for the multi-application module to further comprise at least one UV pre-curing light source, preferably with a UV pre-curing light source arranged on each side of the printing unit, in particular along the two travel directions. Alternatively, it is also possible for the at least one UV pre-curing light source to be remountable, in particular repluggable, on each side of the printing unit, in particular along the two travel directions. This achieves fixing of the print, in particular of the UV-curable ink, directly after printing on the substrate or the transfer product, in particular since irradiation with UV light can occur in both travel directions.

[0059] In other words, the at least one UV pre-curing light source is arranged downstream along the respective running direction to the printing device with respect to the multifunctional element in such a way that fixing can take place directly after printing.

[0060] Preferably, the at least one UV pre-curing light source is a UV LED, in particular which generates light from the wavelength range between 100 nm and 420 nm, preferably between 280 nm and 405 nm, more preferably between 280 nm and 380 nm, even more preferably between 365 nm and 380 nm.

[0061] Further preferably, the distance between the UV pre-curing light source and the, in particular printed, substrate or transfer product is between 1 mm and 50 mm, preferably between 3 mm and 20 mm.

[0062] It is also advisable for the distance between the UV pre-curing light source and the printing unit or the printing table to be between 10 mm and 500 mm, preferably between 30 mm and 100 mm. This allows the UV pre-curing light source to be positioned as close as possible to the printing unit while still allowing the printing unit to be shielded from UV radiation.

[0063] Preferably, the at least one UV pre-curing light source generates an irradiance between 0 W / cm 2 and 10 W / cm 2 , preferably between 0.5 W / cm 2 and 7.5 W / cm 2 , more preferably between 2 W / cm 2 and 5 W / cm 2 . This ensures sufficient fixation of the print, thus achieving high print quality. The precisely selected irradiance depends in particular on the speed of the moving substrate and / or the moving transfer product, depending on what is being printed on, in order to be able to introduce approximately the same energy into the material at different speeds.

[0064] It is expedient if the first multifunctional roller has a diameter between 5 cm and 100 cm, in particular between 10 cm and 50 cm.

[0065] Furthermore, it is expedient if the at least one second multifunctional roller has a diameter between 1 cm and 20 cm, in particular between 3 cm and 10 cm.

[0066] Advantageously, the surface of the first multifunctional roller and / or the at least one second multifunctional roller has a surface structure produced by a surface treatment process. The surface structures can be produced in a convex and / or concave form by one or more surface treatment processes, selected individually or in combination from: blasting, shot blasting, turning, overturning, roughing, grooving, grinding, and creasing.

[0067] It is also advantageous if the first multifunctional roller and / or the at least one second multifunctional roller have an anti-slip coating and / or a traction coating, in particular with a layer thickness between 30 µm and 3 mm, preferably between 50 µm and 100 µm. Thus, it is possible for a rubber coating, for example, to serve as the anti-slip coating. The anti-slip coating can be implemented by structuring in the sense of an introduced relief and / or by applying an additional material layer, in particular a rubber coating, to achieve improved grip for the transfer product and / or the substrate on the first multifunctional roller and / or the at least one second multifunctional roller.

[0068] This ensures, in particular, a secure transport of the substrate or the transfer product on the first multifunctional roller and / or the at least one second multifunctional roller, wherein, in particular, slippage of the transported web, in particular of the substrate or the transfer product, is prevented.

[0069] Advantageously, the first multifunctional roller and / or the at least one second multifunctional roller is driven by an at least partial wrap around the substrate or the transfer product, in particular wherein a constant drive is also achieved or ensured due to the surface roughness or anti-slip coating of the multifunctional roller and the associated non-slip surface of the multifunctional roller.

[0070] It is thus advantageous if the first multifunctional roller and / or the at least one second multifunctional roller is at least partially wrapped around by the substrate or the transfer product, in particular for stable transport in the printing nip.

[0071] It is further preferred if the first multifunctional roller and / or the at least one second multifunctional roller comprises an encoder for detecting and / or controlling the rotational speed of the first multifunctional roller and / or the at least one second multifunctional roller and / or the printing process. This achieves, in particular, precise synchronization of the rotational speed of the first multifunctional roller and / or the at least one second multifunctional roller with the printing unit, thus enabling accurate registration printing.

[0072] Registered or register or precise register or register accuracy or register accuracy refers to the positioning accuracy of two or more layers relative to one another. The register accuracy should be within a specified tolerance and as small as possible. At the same time, the register accuracy of several elements and / or layers with one another is an important feature for increasing process reliability. Precise positioning can be achieved in particular using sensory, preferably optically detectable, fiducials or register marks. These fiducials or register marks can either represent special separate elements or areas or layers or can themselves be part of the elements or areas or layers to be positioned.

[0073] It is thus possible that in the first variant i) the substrate comprises at least one element and / or at least one layer onto which the print is positioned as a further layer in register with this at least one element and / or with the at least one layer on the substrate. Preferably, the position of the at least one element and / or the at least one layer on the substrate or on the transfer product is detected prior to the printing process using an optically detectable registration mark or register mark. By detecting the rotational speed of the multifunctional roller, it is thus possible to determine when the at least one element and / or the at least one layer on the substrate or on the transfer product reaches the printing unit and the print is positioned on the substrate in register therewith.

[0074] In particular, it is provided that the multi-application module comprises at least one detection unit which detects the position of at least one element and / or at least one layer on the substrate and / or the transfer product, in particular by means of a registration mark or register mark, wherein the detection unit is connected to a controller which controls the printing unit on the basis of the detected position data of the detection unit in such a way that the printing on the substrate and / or the transfer product takes place in register with the at least one element and / or the at least one layer.

[0075] It is also possible that in the second variant ii) the substrate comprises at least one element and / or at least one layer, wherein a print applied to the transfer product is positioned relative thereto. The at least one element and / or the at least one layer on the substrate and the print on the transfer product can overlap completely, partially or not at all. Preferably, the position of the at least one element and / or the at least one layer on the substrate is detected using an optically detectable registration mark and the start of the printing process is thus controlled such that the printing on the transfer product is carried out such that the print, after being transported to the press nip between the counterpressure roller and the pressure roller, is pressed in register with the at least one element and / or the at least one layer on the substrate.

[0076] However, it is also possible that in the first variant i) the substrate comprises at least one element and / or at least one layer, with which the print is positioned in register as a further layer. Preferably, the position of the at least one element and / or the at least one layer on the substrate is detected using an optically detectable registration mark positioned upstream of the print. By detecting the rotational speed of the multifunctional roller, it is thus possible to determine when the element or layer on the substrate reaches the printing unit and position the print in register with it.

[0077] Furthermore, it is also possible for the at least one element and / or the at least one layer on the transfer product to be pressed in the press nip between the counterpressure roller and the pressure roller in register with the at least one element and / or the at least one layer and / or the print on the substrate. For this purpose, it is expedient if the position of the at least one element and / or the at least one layer both on the substrate and on the transfer product is detected by an optically detectable registration mark or register mark assigned to the transfer product and the substrate, and if the positioning is carried out via the stretching of the transfer product, so that after the transfer product has been transported to the press nip between the counterpressure roller and the pressure roller, the at least one element or the at least one layer on the transfer product is pressed in register with the at least one element and / or the at least one layer on the substrate.This results in a register between the at least one element or the at least one layer on the substrate, the print and the transfer product.

[0078] In particular, it is provided that the cold stamping unit comprises at least one detection unit which detects the position of at least one element and / or at least one layer on the substrate and / or the transfer product, in particular by means of a registration mark or register mark, and the positioning takes place via the stretching of the transfer product, so that after the transfer product has been transported to the press nip, the pressure roller presses the at least one element and / or the at least one layer on the transfer product in register onto the at least one element and / or the at least one layer on the substrate.

[0079] Furthermore, it is also possible that in the second variant ii) the substrate comprises at least one element and / or at least one layer, with which at least one element and / or at least one layer on the transfer product is pressed in register with the at least one element or the at least one layer on the substrate in the press nip between the counterpressure roller and the pressure roller. For this purpose, it is expedient if the print is positioned in register with the at least one element and / or the at least one layer on the transfer product. Preferably, the position of the at least one element and / or the at least one layer both on the substrate and on the transfer product is detected by means of an optically detectable registration mark or registration mark on the transfer product and on the substrate, which is respectively assigned to the transfer product and the substrate, and is positioned via the stretching of the transfer product.The at least one element and / or the at least one layer on the substrate and the transfer product can each overlap completely, partially, or not at all. This results in a register between the at least one element or the at least one layer on the substrate, the print, and the transfer product.

[0081] In particular, it is expedient if, for the stretching of the transfer product in the first variant i), for positioning at least one element and / or at least one layer on the transfer product in register with the at least one element and / or the at least one layer on the substrate, the tensioning system is used after the film unwinding.

[0082] It is also possible for the multi-application device to have a transfer product transport system with a clamping system for controlled material transport, wherein the transfer product transport system controls the register-accurate positioning in the press nip of the at least one element and / or the at least one layer on the transfer product and the at least one element and / or the at least one layer on the substrate via the stretching of the transfer product by means of the clamping system. Preferably, the transfer product transport system comprises at least one driven roller influencing the transport speed of the transfer product and a detection unit, in particular an optical sensor, for detecting the position of the at least one element and / or the at least one layer on the transfer product by means of an optically detectable registration mark or register mark applied to the transfer product.Such a driven roller can comprise one or more of the following elements, selected individually or in combination: roller with opposing press roller, roller with at least one or more segmented press rollers, vacuum roller.

[0084] Alternatively, the stretching of the transfer product can also be enabled via at least one drive on the multifunctional roller, wherein the speed of the transfer product transport on the multifunctional roller relative to the speed of the substrate transport in the press nip between the counterpressure roller and the pressure roller can be used to influence the stretching of the transfer product in the area between the multifunctional roller and the press nip and thus to control the positioning of the at least one element and / or the at least one layer on the transfer product in register with the at least one element and / or the at least one layer on the substrate.

[0085] According to the invention, the printing unit comprises at least one inkjet print head.

[0086] According to the invention, the printing unit is or comprises a UV inkjet print bar, in particular with one or more inkjet print heads.

[0087] The UV inkjet print bar expediently has a printing width transverse to the feed direction of the substrate and / or the transfer product between 50 mm and 2000 mm, in particular between 100 mm and 1000 mm.

[0088] It is possible that the UV inkjet print bar and / or one or more inkjet print heads have a resolution of 300 to 1200 npi ( engl. nozzles per inch). This resolution is perpendicular to the feed direction of the transfer product and / or the substrate and is particularly dependent on the design. It is also possible that the UV inkjet print bar and / or the one or more inkjet print heads have a resolution of 300 to 2400 dpi ( engl. dots per inch). This resolution is seen in the feed direction of the transfer product and / or the substrate and is in particular electronically controllable or modifiable, preferably in order to change the application quantity of the ink.

[0089] Furthermore, it is possible for the UV inkjet print bar and / or the one or more inkjet print heads to have a maximum printing speed of 300 m / min, preferably a maximum printing speed of 200 m / min.

[0092] This ensures, in particular, that the optimal ink is directly available for both printing on the substrate and printing on the transfer product, enabling automatic ink changes when using a single printing unit.

[0093] Between ink changes, it is advantageous to perform a cleaning process to remove any residue from the first ink from the ink supply system and the print head before the second ink is added. Especially since the substrate and the transfer product typically have different physical properties, such as absorbency or surface texture, the most suitable ink can be used directly without first having to refill the printing unit.

[0094] Preferably, the printing unit is configured by means of a digital program so that it can print along the two running directions.

[0095] In In other words, it is useful if the printing unit is configured by means of a digital program in such a way that it can print both according to the first variant i) and according to the second variant ii).

[0101] Thus, it is expedient if, according to a first variant, i) the substrate can be guided along the multifunctional roller, in particular when rotating in a first direction of rotation, to the printing nip (or in the direction of the printing nip) for printing the substrate, or that, according to a second variant, ii) the transfer product can be guided along the multifunctional roller, in particular when rotating in a second direction of rotation opposite to the first direction of rotation, to the printing nip (or in the direction of the printing nip) for printing the transfer product, preferably wherein the substrate or the transfer product can be printed in the same printing nip.

[0120] Furthermore, it is possible for the cold transfer unit to further comprise at least one further UV final curing light source, in particular wherein the further UV final curing light source is arranged downstream or after the release roller or the release blade, in particular in the running direction of the substrate.

[0121] In this case, it is expedient if the at least one further UV final curing light source is arranged, in particular in the conveying direction of the substrate, between 5 cm and 50 cm, in particular between 5 cm and 20 cm downstream or after the release roller or the release blade.

[0122] Preferably, the at least one UV final curing light source and / or the at least one further UV final curing light source is a UV LED, in particular which generates light from the wavelength range between 100 nm and 420 nm, preferably between 280 nm and 405 nm, more preferably between 280 nm and 380 nm, even more preferably between 365 nm and 380 nm.

[0123] Preferably, the at least one final UV curing light source and / or the at least one further final UV curing light source generates an irradiance between 5 W / cm 2 and 50 W / cm 2 , preferably between 15 W / cm 2 and 25 W / cm 2 . The precisely selected irradiance depends in particular on the speed of the moving substrate and / or the moving transfer product, depending on what is being printed on, in order to be able to introduce approximately the same energy into the material at different speeds.

[0124] It is particularly preferred that one or more components, in particular for adjusting an entry angle α of the transfer product into a press nip formed by a pressure roller and a counter-pressure roller, are provided, selected from the group: pressure roller, at least one UV final curing light source, detachment roller or detachment blade, at least one further UV final curing light source, which can be pivoted around the counter-pressure roller.

[0125] Advantageously, the inlet angle α is formed by two legs, the first leg being a half-line whose starting point is the center of the press nip and which is tangent to the counter-pressure roller or the pressure roller, and the second leg being a half-line whose starting point is the first contact point of the transfer product and / or the substrate with the surface of the counter-pressure roller or the pressure roller and which is tangent to the counter-pressure roller or the pressure roller.

[0126] Preferably, the press nip is the nip that represents the shortest distance between the circumferential surfaces of the counter-pressure roller and the pressure roller.

[0127] The inlet angle α is preferably at least 5°, particularly preferably at least 10°. In particular, the inlet angle α has this minimum value when the diameter of the respective roller is between 5 cm and 50 cm.

[0128] It is also particularly preferred that the cold transfer unit is displaceable relative to the multi-application module, in particular for adjusting an entry angle α of the transfer product into a press nip formed by a pressure roller and a counter-pressure roller.

[0129] In particular, it is advantageous if one or more components selected from the group: pressure roller, at least one UV final curing light source, release roller or release blade, at least one further UV final curing light source, are pivotable, in particular about the counter-pressure roller, in such a way that the respective entry angles α of the transfer product and / or the substrate into a press nip formed by the pressure roller and the counter-pressure roller can be adjusted for the first variant i) and the second variant ii), in particular in order to maintain the minimum value of the entry angle α.

[0130] It is also further advantageous if the cold transfer unit is displaceable relative to the multi-application module in such a way that the respective inlet angles α of the transfer product and / or the substrate into a press nip formed by a pressure roller and a counter-pressure roller can be adjusted for the first variant i) and the second variant ii), in particular in order to maintain the minimum value of the inlet angle α.

[0135] Advantageously, the pressure roller and / or the counter-pressure roller are driven, in particular such that the counter-pressure roller rotates clockwise or counter-clockwise.

[0136] For example, it is possible for the counterpressure roller to rotate clockwise. In this case, for example, the first multifunction roller and / or the at least one second multifunction roller also rotate clockwise to print on the substrate, whereas the first multifunction roller and / or the at least one second multifunction roller rotate counterclockwise to print on the transfer product.

It is also possible to invert all directions of rotation.

[0138] Furthermore, the winding rollers can accommodate either one or more transfer product rolls.

In this case, it is expedient if the release roller 20 is arranged, in particular in the conveying direction of the substrate 6 and / or the transfer product 7, between 5 cm and 50 cm, in particular between 5 cm and 20 cm, downstream in the conveying direction of the substrate 6 and / or the transfer product 7 or after the UV final curing light source 19a. It is also expedient if the release roller 20 has a diameter of between 0.5 cm and 10 cm, over which the carrier layer can be peeled off. As an alternative to the release roller 20, a release blade can also be used to detach a carrier layer from a transfer layer of the transfer product 7.

[0182] The UV final curing light source 19a is preferably a UV LED, in particular one that generates light in the wavelength range between 100 nm and 420 nm, preferably between 280 nm and 405 nm, more preferably between 280 nm and 380 nm, and even more preferably between 365 nm and 380 nm. Preferably, the at least one UV final curing light source 19a generates an irradiance of between 5 W / cm 2 and 50 W / cm 2 , preferably between 15 W / cm 2 and 25 W / cm 2 .

[0183] Furthermore, as the Fig. 1c can also be removed, the cold transfer unit 5 can also have one or more deflection or guide rollers 15.

[0184] Fig. 2a bis Fig. 2c show schematically a sectional view of a multi-application module 1 and a sectional view of a system 4.

[0185] The Fig. 2a Multi-application module 1 shown corresponds to the one in Fig. 1a shown multi-application module 1 and serves here to illustrate how in the following Fig. 2b und 2c the multi-application module 1 is used in conjunction with the cold transfer unit 5 to apply a transfer layer of a transfer product 7 to a substrate 6. The Fig. 2a The multi-application module 1 shown is therefore a component of the Fig. 2b und 2c multi-application device 2 shown or the one in Fig. 2b und 2c shown system 4, in particular which is shown in the Fig. 2b und 2c has different substrate pathways and transfer product pathways.

[0186] The Fig. 2a und 2b The system 4 shown or the multi-application device 2 serves to apply a transfer layer of a transfer product 7 to a substrate 6, wherein the multi-application module 1 contained in the system 4 or in the multi-application device 2 serves to print the substrate 6 or the transfer product 7, in particular with a UV-curable ink.

[0187] The Fig. 2b System 4 shown includes the already in Fig. 1c multi-application device 2 shown and further a substrate 6 and a transfer product 7. In the Fig. 2b In the variant shown, the substrate 6 is first guided in the cold transfer unit 5 over a deflection roller 15 along the counter-pressure roller 18 and from there over another deflection roller 15 to the first multifunctional roller 91. The substrate 6 wraps around the first multifunctional roller 91 and thus drives it. Via the first multifunctional roller 91, the substrate 6 is fed to the printing nip 10, in which the substrate 6 is printed by the printing unit 8.

[0188] The printing is carried out on the substrate 6 using a UV-curable ink, which serves particularly as an adhesive. The printing can be applied over the entire surface or only in specific areas, i.e., in partial areas. Preferably, the printing is in the form of a pattern or motif.

[0189] The term “region” or “partial region” or “regionally” is understood to mean a defined area of ​​a layer or ply which, when viewed perpendicular to a plane spanned by the substrate 6 or transfer product 7.

[0190] The substrate 6 is then fed to a press nip formed by a pressure roller 17 and a counterpressure roller 18, in which the substrate 6 is brought together with the transfer product 7. The print from the UV-curable ink is then cured by means of the UV final curing light source 19a through the transfer product 7 through the action of the UV light, so that in the printed areas the transfer product 7 bonds with the substrate 6 through curing. The transfer product 7 is then peeled off the substrate 6 again, so that only the transfer layer of the transfer product 7 remains in the previously printed areas. This separation takes place by means of the release roller 20. Subsequently, as in Fig. 2b shown, the substrate 6 is guided out of the cold transfer unit via a deflection roller 15.

[0191] The path of transfer product 7 runs in Fig. 2b from the winding roller 12a to the press nip formed by the pressure roller 17 and the counterpressure roller 18, where the transfer product 7, as explained above, is brought together with the substrate 6 and the transfer layer of the transfer product 7 is at least partially transferred to the substrate 6. After the separation of the substrate 6 and the transfer product 7 on the release roller 20, which has also already been explained above, the transfer product 7 is fed via a deflection roller 15 to the winding roller 12b, on which the transfer product 7 is rewound.

[0192] In the Fig. 2b In the variant shown, the first multifunctional roller 91 therefore rotates, for example, clockwise and the printing takes place along this running direction of the substrate 6 predetermined by the first multifunctional roller 91.

[0193] According to the Fig. 2b In the variant shown, the substrate 6 is guided along the first multifunctional roller 91 to the printing gap 10 formed between the printing unit 8 and the first multifunctional roller 91, which functions as a multifunctional element 9, for printing the substrate 6 and then further to the counterpressure roller 18 and the pressure roller 17, with which the transfer product 7 is pressed onto the substrate 6.

[0194] The Fig. 2c System 4 shown corresponds to the one in Fig. 2b shown system, where the substrate and transfer product pathways are changed. Fig. 2c System 4 shown therefore also includes the already mentioned Fig. 1c multi-application device 2 shown and further a substrate 6 and a transfer product 7. In the Fig. 2c However, in the variant shown, the transfer product 7 is guided from the winding roller 12a over the first multifunctional roller 91. As Fig. 2c As can be seen, the transfer product 7 wraps around the first multifunctional roller 91 and thus drives it. The transfer product 7 is fed via the first multifunctional roller 91 to the printing nip 10, in which the transfer product 7 is printed by the printing unit 8.

[0195] Here, too, printing on the transfer product 7 is carried out using a UV-curable ink, which serves primarily as an adhesive. This printing can also be applied over the entire surface or only in specific areas, i.e., in partial areas. Preferably, the printing is also done in the form of a pattern or motif.

[0196] The transfer product 7 is then fed to a press nip formed by a pressure roller 17 and a counter-pressure roller 18, by bringing the transfer product 7 together with the substrate 6.

[0197] The substrate 6 is in the Fig. 2c shown variant is fed via a deflection roller 15 and the counter-pressure roller 18 to the press nip formed by the pressure roller 17 and the counter-pressure roller 18.

[0198] The connection of transfer product 7 and substrate 6 is analogous to the one already described in Fig. 2b described variant, so reference is made to the above explanations. The further paths of the substrate 6 and the transfer product 7 also correspond to those already described in connection with Fig. 2b described ways, so that reference is also made to the above explanations in this regard.

[0199] In the Fig. 2c In the variant shown, the first multifunctional roller 91 therefore rotates, for example, counterclockwise and the printing takes place along this running direction of the transfer product 7 predetermined by the first multifunctional roller 91.

[0200] According to the Fig. 2c In the variant shown, the transfer product 7 is guided along the first multifunctional roller 91 to the printing gap 10 formed between the printing unit 8 and the first multifunctional roller 91, which functions as a multifunctional element 9, for printing the transfer product 7 and further to the counterpressure roller 18 and pressure roller 17, with which the transfer product 7 is pressed onto the substrate 6.

[0201] Like the Fig. 2b und 2c As can be seen, the first multifunctional roller 91 rotates in the variants of the Fig. 2b und 2c each in an opposite direction of rotation.

[0202] Preferably, the printing unit 8 is configured by means of a digital program so that it can print along the two running directions. In other words, it is expedient if the printing unit 8 is configured by means of a digital program such that it can print according to the Fig. 2b shown variant as well as according to the Fig. 2b shown variant can be printed.

[0203] The Fig. 2b und 2c thus show a (working) method for a multi-application device 2, wherein the multi-application device 2 comprises a multi-application module 1 with a printing unit 8 and a first multi-function roller 91 as a multi-function element 9 and a cold transfer unit 5 with a pressure roller 17 and a counter-pressure roller 18, wherein a printing nip 10 is formed between the printing unit 8 and the first multi-function roller 91, wherein according to a first variant i) a substrate 6 is guided along the first multi-function roller 91 to the printing nip 10 for printing the substrate 6 and further to the counter-pressure roller 18 and the pressure roller 17, with which a transfer product 7 is pressed onto the substrate 6, or wherein according to a second variant ii) the transfer product 7 is guided along the first multi-function roller 91 to the printing nip 10 for printing the transfer product 7 and further to the counter-pressure roller 18 and the pressure roller 17,with which the transfer product 7 is pressed onto the substrate 6, and wherein the first multifunctional roller 91 in variants i) and ii) rotates in an opposite direction of rotation.

[0204] As in the Fig. 2b und 2c As shown, it is therefore possible that both variants i) and ii) can be selected and / or executed in the same multi-application device 2 or are executed by the same multi-application device 2, in particular whereby this is made possible by the multi-application module 1, which comprises a first multi-function roller 91 which is rotatably mounted in two opposite directions of rotation, and whose printing unit 8 is designed such that it can print in the printing nip 10 along two running directions which are predetermined by the two opposite directions of rotation.

[0205] Fig. 3 shows a schematic sectional view of a multi-application module 1 and a cold transfer unit 5.

[0206] The Fig. 3 The multi-application module 1 shown corresponds to the one shown in Fig. 1a multifunctional module shown, so that with regard to its design, reference is made to the above explanations. The cold transfer unit 5 also corresponds to the Fig. 1c shown cold transfer unit 5 with the difference that the cold transfer unit 5 is designed as an extension module 22. Thus, the multi-application module 1 can be used in particular in processing machines, such as a flexographic printing machine, with an existing printing unit, here a flexographic printing unit, which fulfills the function of the cold transfer unit. Regarding the further design of the cold transfer unit 5, reference is made to the above statements, for example in connection with the Fig. 1c , referred to.

[0207] It is also possible here that an adapter is arranged between the multi-application module 1 and the cold transfer unit 5, which adapter in particular enables a mechanically stable fastening of the multi-application module 1 to the cold transfer unit 5.

[0208] Fig. 4 shows a schematic sectional view of a multi-application device 2.

[0209] The Fig. 4 The multi-application device 2 shown comprises a printing unit 8 and a multifunctional element 9, wherein a printing gap 10 is formed between the printing unit 8 and the multifunctional element 9. In this embodiment, the multifunctional element comprises a first multifunctional roller 91 and a printing table 13 arranged thereabove. The printing gap 10 is therefore preferably formed between the printing unit 8 and the printing table 13.

[0210] To enable printing on both a substrate 6 and a transfer product 7 using the multi-application device 2, the first multi-function roller 91 is mounted for rotation in two opposite directions. Furthermore, the printing unit 8 is configured such that it can print in the printing nip 10 along two directions of travel, which are determined by the two opposite directions of rotation.

[0211] Regarding the further design of the printing unit 8 and the first multifunctional roller 91, reference is made to the above statements, for example in connection with the Fig. 1a , referred to.

[0212] Furthermore, the Fig. 4 shown multi-application device 2, here the winding rollers 12a and 12b, wherein reference is also made to the above explanations with regard to their design.

[0213] How is Fig. 4 As shown, the multi-application device 2 can further comprise one or more clamping systems 16 for clamping the transfer product 7, wherein the clamping systems 16 are selected individually or in combination. The clamping system can comprise one or more of the following elements, selected individually or in combination: dancer roller, controlled dancer roller, measuring roller, friction shaft.

[0214] The Fig. 4 The printing table 13 shown is arranged such that the substrate 6 or the transfer product 7 can be guided over the printing table 13.

[0215] The printing table 13 preferably forms a flat surface, in particular between 250 mm 2 and 1,000,000 mm 2 , more preferably between 1,000 mm 2 and 200,000 mm 2 . It is furthermore preferred if the printing table 13 is arranged perpendicular to the printing unit 8. It is also possible for ink to be ejected from the printing unit 8 perpendicularly, i.e. perpendicular to the flat surface of the printing table. It is furthermore also possible for the printing table to have a length in the feed direction of the substrate 6 and / or the transfer product 7 of between 5 mm and 500 mm, in particular between 10 mm and 100 mm, and / or a width transverse to the feed direction of the substrate 6 and / or the transfer product 7 of between 50 mm and 2,000 mm, in particular between 100 mm and 1,000 mm.It is also expedient if the distance between the printing unit 8 and the flat printing surface of the substrate 6 or the transfer product 7, which is guided over the printing table 13, is between 0.1 mm and 5 mm, preferably between 0.5 mm and 3 mm.

[0216] It is also possible for the printing table 13 to have air outlets for generating an air cushion, in particular an air cushion between the printing table 13 and the substrate 6 or the transfer product 7.

[0217] As already explained above, a UV-curable ink is preferably printed using the printing unit 8.

[0218] It is expedient for the multi-application device 2 to further comprise at least one UV pre-curing light source 14, preferably with a UV pre-curing light source 14 being arranged on each side of the printing unit 8, in particular along the two travel directions. It is also possible for the at least one UV pre-curing light source 14 to be arranged in a relocatable, in particular repluggable, manner on each side of the printing unit 8, in particular along the two travel directions. The UV-curable ink can be fixed by means of the UV pre-curing light sources 14 in order to prevent the UV-curable ink from running during the further transport of the substrate 6 or the transfer product 7 to the press nip formed by the pressure roller 17 and the counter-pressure roller 18.

[0219] The Fig. 4 The multi-application device 2 shown here has two UV pre-curing light sources 14 on each side of the printing unit 8.

[0220] Preferably, the at least one UV pre-curing light source 14 is a UV LED, in particular which generates light from the wavelength range between 100 nm and 420 nm, preferably between 280 nm and 405 nm, more preferably between 280 nm and 380 nm, even more preferably between 365 nm and 380 nm.

[0221] Further preferably, the distance between the UV pre-curing light source 14 and the, in particular printed, substrate 6 or transfer product 7 is between 1 mm and 50 mm, preferably between 3 mm and 20 mm.

[0222] It is also expedient if the distance between the UV pre-curing light source 14 and the printing unit 8 or the printing table 13 is between 10 mm and 500 mm, preferably between 30 mm and 100 mm.

[0223] Preferably, the at least one UV pre-curing light source 14 generates an irradiance between 0 W / cm 2< to 10 W / cm 2< , preferably between 0.5 W / cm 2< to 7.5 W / cm 2< , more preferably between 2 W / cm 2< to 5 W / cm 2< .

[0224] The Fig. 4 The multi-application device 2 shown further comprises a pressure roller 17, a counterpressure roller 18, a release roller 20 and a UV final curing light source 19a, with regard to the design of which reference is made to the above explanations. Furthermore, the Fig. 4 The multi-application device 2 shown also has the deflection or guide rollers 15, by means of which a substrate 6 or a transfer product 7 is guided through the multi-application device 2.

[0225] The Fig. 4 The multi-application device shown here comprises the additional UV final curing light source 19b. The additional UV final curing light source 19b is arranged downstream of the release roller 20, in particular in the travel direction of the substrate 6. Thus, it is expedient if the additional UV final curing light source 19b is arranged, in particular in the conveying direction of the substrate 6, between 5 cm and 50 cm, in particular between 5 cm and 20 cm downstream of or after the release roller 20. Regarding the further configuration of the additional UV final curing light source 19b, reference is made to the above explanations in connection with the UV final curing light source 19a.

[0226] Also the Fig. 4 The multi-application device 2 shown has, as shown in the following Fig. 5a und 5b as well as Fig. 6a und 6b each shown by the dashed line, here comprises a multi-application module 1 and a cold transfer unit 5, wherein the multi-application module 1 comprises at least the printing unit 8 and the multifunctional element 9 together with the associated printing nip 10, and wherein the cold transfer unit 5 comprises at least the pressure roller 17 and the counter-pressure roller 18. In addition, the Fig. 4 The multifunctional element 9 shown comprises a first multifunctional roller 91 and a printing table 13 arranged above it. The associated printing gap 10 is accordingly formed between the printing unit 8 and the printing table 13.

[0227] Fig. 5a und 5b shows a schematic sectional view of a system 4. The system 4 comprises, in addition to the multi-application device 2, a substrate 6 and a transfer product 7, wherein the substrate and transfer product path extends between the Fig. 5a shown variant of system 4 and the one in Fig. 5b shown variant of system 4. The Fig. 5a und 5b therefore also show schematic sectional views of a multi-application device 2, which in particular further comprise a substrate 6 and a transfer product 7. Thus, in Fig. 5a und 5b also a (working) method of a multi-application device 2 is shown that the Fig. 5a und 5b shown variants.

[0228] According to the Fig. 5a In the variant of a (working) method for a multi-application device shown, a substrate 6 is guided along a multi-function element 9 to a printing gap 10 formed between a printing unit 8 and the multi-function element 9 for printing the substrate 6. The multi-function element 9 comprises a first multi-function roller 91 and a printing table 13 arranged above it. The printing gap 10 is therefore formed between the printing unit 8 and the printing table 13. The substrate 6 is then guided to a counter-pressure roller 18 and a pressure roller 17, with which a transfer product 7 is pressed onto the substrate 6. According to the Fig. 5b In the variant of the (working) method for a multi-application device 2 shown, the transfer product 7 is guided along the multifunctional element 9 to the printing gap 10 formed between the printing unit 8 and the multifunctional element 9 for printing the transfer product 7. The multifunctional element 9 comprises a first multifunctional roller 91 and a printing table 13 arranged above it. The printing gap 10 is therefore formed between the printing unit 8 and the printing table 13. The transfer product 7 is then guided to the counterpressure roller 18 and the pressure roller 17, with which the transfer product 7 is pressed onto the substrate 6. In the Fig. 5a und 5b In the variants of the (working) method for a multi-application device 2 shown, the first multi-function roller 91 rotates in an opposite direction of rotation.

[0229] This is how it works in Fig. 5a In the variant shown, the substrate 6 is first guided a short distance along the counter-pressure roller 18 to the first multifunctional roller 91 via a deflection roller 15. From the first multifunctional roller 91, the substrate 6 is then guided over the printing table 13, on which the printing process takes place by means of the printing unit 8 in the printing gap 10, which is formed between the printing table 13 or the multifunctional element 9 and the printing unit 8. A UV-curable ink is preferably used as the printing material. From the printing table 13, the substrate 6 is guided back to the first multifunctional roller 91, which is partially wrapped around by the substrate 6, so that the substrate 6 can drive the first multifunctional roller 91. After the printing process in the printing gap 10, the printed material is fixed by means of the UV pre-curing light source 14. The UV pre-curing light source 14 is therefore arranged downstream of the printing.Subsequently, the substrate 6 is brought together with the transfer product 7 in the press nip formed between the pressure roller 17 and the counterpressure roller 18 and pressed together. For this purpose, the transfer product 7 is guided from the winding roller 12a via a tensioning system 16 and a deflection roller 15 to the press nip. The tensioning systems 16 ensure that the transfer product 7 is transported under tension. As shown in . Fig. 5a As shown, the substrate 6 and the transfer product 7 now run simultaneously over a common path on the counter-pressure roller 18. On this common path, the print is cured through the transfer product 7 by means of a UV final curing light source 19a. Through the curing, the transfer product 7 or the transfer layer of the transfer product 7 bonds to the substrate 6 in those areas in which the print, in particular the UV-curable ink, was previously applied. Subsequently, by means of the release roller 20, as shown in Fig. 5a As shown, the transfer product 7 is separated again from the substrate 6, whereby the transfer layer of the transfer product 7 remains on the substrate 6 in the previously printed areas. The transfer product 7 is then wound onto the winding roller 12b via a deflection roller 15 and a tensioning system 16. The substrate 6, now at least partially decorated with the transfer layer 7, is guided out of the system 4 or the multi-application device 2 via a deflection roller 15.

[0230] At the Fig. 5b In the variant shown, however, the substrate 6 is guided via a deflection roller 15 onto the counter-pressure roller 15, which is at least partially wrapped around by the substrate 6. On the counter-pressure roller 15, the substrate 6 is then guided to the press nip formed by the pressure roller 17 and the counter-pressure roller 18. The transfer product 7, on the other hand, is guided from the winding roller 12a via a tensioning system 16 and a deflection roller 15 to the first multi-function roller 91. From the first multi-function roller 91, the transfer product 7 is then guided over the printing table 13, on which the printing process takes place by means of the printing unit 8 in the printing nip formed between the printing table 13 or the multi-function element 9 and the printing unit 8. A UV-curable ink is preferably used as the printing material.From the printing table 13, the transfer product 7 is guided back onto the first multifunctional roller 91, which is partially wrapped around the transfer product 7, so that the transfer product 7 can drive the first multifunctional roller 91. After the printing process in the printing nip 10, the printed material is fixed by means of the UV pre-curing light source 14. The UV pre-curing light source 14 is therefore arranged downstream of the printing process. In the case of the . Fig. 5a und 5b The UV pre-curing light source 14 shown is a removable UV pre-curing light source 14 that can be mounted on either side of the printing unit 8, depending on whether the substrate 6 or the transfer product 7 is to be printed. Subsequently, the transfer product 7 is brought together with the substrate 6 in the press nip formed between the pressure roller 17 and the counter-pressure roller 18 and pressed. As shown in Fig. 5b As shown, the substrate 6 and the transfer product 7 now run simultaneously over a common path on the counter-pressure roller 18. On this common path, the print is cured through the transfer product 7 by means of a UV final curing light source 19a. Through the curing, the transfer product 7 or the transfer layer of the transfer product 7 bonds to the substrate 6 in those areas in which the print, in particular the UV-curable ink, was previously applied. Subsequently, by means of the release roller 20, as shown in Fig. 5b As shown, the transfer product 7 is separated again from the substrate 6, whereby the transfer layer of the transfer product 7 remains on the substrate 6 in the previously printed areas. The transfer product 7 is then wound onto the winding roller 12b via a deflection roller 15 and a tensioning system 16. The substrate 6, now at least partially decorated with the transfer layer, is guided out of the system 4 or the multi-application device 2 via a deflection roller 15.

[0231] Regarding the design of the Fig. 5a und 5b The parts or components shown here refer to the above statements, for example in the context of Fig. 4 , referred to.

[0232] According to the system 4, which comprises a multi-application device 2 with a multi-application module 1 and a cold transfer unit 2 and further comprises a substrate 6 and a transfer product 7, the system 4 is also Fig. 5a und 5b shown printing system 3 to the one shown in the Fig. 5a und 5b shown multi-application module 1, which further comprises the substrate 6 and / or the transfer product 7.

[0233] As in the Fig. 5a und 5b As shown, the substrate 6 or the transfer product 7 can be guided by means of the first multifunctional roller 91. Thus, it is possible for the substrate 6 guided on the first multifunctional roller 91 or the transfer product 7 guided on the first multifunctional roller 91 to be printed in two opposite running directions by means of the printing unit 8 in the printing nip 10, in particular wherein the directions of rotation of the first multifunctional roller 91 are opposite when guiding the substrate 6 and the transfer product 7.

[0234] How Fig. 5a und 5b can be taken, both the Fig. 5a shown variant as well as the one in Fig. 5b The variant shown is carried out by the same multi-application device 2 or the same system 4, in particular, wherein the substrate and transfer product paths within the multi-application device 2 differ, as described above. Thus, the printing of the substrate 6 or the transfer product 7 takes place in the same multi-application module 1, wherein the substrate travel direction and the transfer product travel direction or transport directions differ, in particular being opposite.

[0235] The next thing is the Fig. 5a shown variant, the first multifunctional roller 91 rotates clockwise, whereas in the variant shown Fig. 5b shown variant, the first multi-function roller 91 rotates counterclockwise. As shown in the Fig. 5a und 5b As shown, the counter-pressure roller 18 rotates clockwise in both variants.

[0236] As can be seen from the above explanations, one and the same machine is used here according to the Fig. 5a shown variant, the substrate 6 is printed and then combined with the transfer product 7, whereas according to the variant shown in Fig. 5b shown variant, the transfer product 7 is printed and then combined with the substrate 6.

[0237] Fig. 6a und 6b shows a schematic cross-sectional view of a system 4.

[0238] The Fig. 6a und 6b System 4 shown corresponds to the one shown in the Fig. 5a und 5b shown system with the difference that one or more components selected from the group: pressure roller 17, at least one UV final curing light source 19a, release roller 20 and optionally at least one further UV final curing light source 19b, can be pivoted about the counter-pressure roller 18, in particular for adjusting an entry angle α of the transfer product 7 into a press nip formed by the pressure roller 17 and the counter-pressure roller 18.

[0239] Like the Fig. 6a und 6b can be removed and is marked by an arrow, the Fig. 6b shown pressure roller 17, UV final curing light source 19a and release roller 20 compared to the one shown in Fig. 6a shown pressure roller 17, UV final curing light source 19a and release roller 20 are pivoted such that the inlet angle α into the press nip in both in the Fig. 6a und 6b shown variants can maintain a minimum value.

[0240] Fig. 7a und 7b shows a schematic cross-sectional view of a system 4.

[0241] The Fig. 7a und 7b System 4 shown corresponds to the one shown in the Fig. 5a and 5b shown system with the difference that the cold transfer unit 5 is displaceable relative to the multi-application module 1, in particular for adjusting an entry angle α of the transfer product 7 into a press nip formed by the pressure roller 17 and the counter-pressure roller 18.

[0242] Like the Fig. 7a and 7b can be removed and is marked by an arrow, the Fig. 7b shown cold transfer unit 5 is shifted in such a way that the inlet angle α into the press nip in both the Fig. 7a and 7b shown variants can maintain a minimum value.

[0243] In the Figures 8a to 8fVarious embodiments of the multifunctional element 9 of a multi-application module 1 are shown by way of example. In each illustration, a printing unit 8 is additionally arranged above the multifunctional element 9, which is intended to clarify the positioning of the multifunctional element 9 relative to the printing unit 8.

[0244] In Fig. 8aThe multifunctional element 9 comprises only the first multifunctional roller 91. Thus, the printing gap is formed between the printing unit 8 and the first multifunctional roller 91. The first multifunctional roller 91 is preferably at least partially wrapped around by the substrate 6 or the transfer product 7, so that the multifunctional roller 91 is driven by the substrate 6 or the transfer product 7. The ink ejection of the printing unit 8 preferably takes place perpendicular to the peripheral edge of the first multifunctional roller 91. In this embodiment, it is preferably provided that the first multifunctional roller 91 has the largest possible diameter, so that the curvature in the printing area is as small as possible. This ensures high print quality. Fig. 8aThe first multifunctional roller 91 shown is rotatably mounted and can therefore rotate in two opposite directions. As described above, the direction of rotation depends on whether a substrate 6 or a transfer product 7 is being printed.

[0245] In Fig. 8b The multifunctional element 9 comprises a first multifunctional roller 91 and a printing table 13 arranged above it. Thus, the printing gap is formed between the printing unit 8 and the printing table 13. As in the embodiment according to Fig. 8a , the first multifunctional roller 91 is at least partially wrapped around the substrate 6 or the transfer product 7, so that the first multifunctional roller 91 is driven by the substrate 6 or the transfer product 7. As in Fig. 8bAs shown, the substrate 6 or the transfer product 7 is guided over the printing table 13. The printing table 13 then preferably forms a flat surface, which functions as the printing surface. Printing on a flat surface ensures high print quality and printing accuracy.

[0246] In Fig. 8c The multifunctional element 9 comprises only a printing table 13. Thus, even in the Fig. 8c In the embodiment shown, the printing gap 10 is formed between the printing unit 8 and the printing table 13. The substrate 6 or the transfer product 7 is guided over the printing table 13. In preferred embodiments, it is possible for the printing table 13 itself to have rollers and / or cylinders, in particular which are integrated into the printing table 13, in order to enable better running properties of the substrate 6 or the transfer product 7.

[0247] In Fig. 8dthe multifunctional element 9 comprises a first multifunctional roller 91 and two second multifunctional rollers 92. The substrate 6 or the transfer product 7 wraps around the first multifunctional roller 91 at least partially, whereby the first multifunctional roller 91 is driven. After the first point of contact of the substrate 6 or the transfer product 7 with the first multifunctional roller, the substrate 6 or the transfer product 7 is guided onto the first second multifunctional roller 92 and is removed again via the second second multifunctional roller 92 to the first multifunctional roller 91. This means that the substrate 6 or the transfer product 7 is clamped between the two second multifunctional rollers 92 in such a way that the substrate 6 or the transfer product 7 forms a flat printing surface. The printing gap 10 is in the Fig. 8dIn the embodiment shown, the support rollers 91 and 92 are formed between the flat printing surface or between the two second multifunctional rollers 92 and the printing unit 8. High print quality and printing accuracy are also promoted by clamping the substrate 6 or the transfer product 7 to form a flat printing surface using the second multifunctional rollers. Preferably, both the first multifunctional roller 91 and the second multifunctional rollers 92 are mounted for rotation in two opposite directions. As previously described, the direction of rotation depends on whether the substrate 6 or the transfer product 7 is being printed.

[0248] In Fig. 8e The multifunctional element 9 comprises two second multifunctional rollers 92. The substrate 6 or the transfer product 7 wraps around the two second multifunctional rollers 92 at least partially and is driven thereby. As already described in Fig. 8d shown, is also shown in the execution according to Fig. 8eThe substrate 6 or the transfer product 7 is clamped between the two second multifunctional rollers 92 to form a flat printing surface. This enables high print quality and printing accuracy. Preferably, the second multifunctional rollers 92 are mounted for rotation in two opposite directions, which depend on whether the substrate 6 or the transfer product 7 is being printed.

[0249] In Fig. 8f The multifunctional element 9 comprises a first multifunctional roller 91 and a second multifunctional roller 92. Both the first multifunctional roller 91 and the second multifunctional roller 92 are at least partially wrapped around by the substrate 6 or the transfer product 7 and driven by the substrate 6 or the transfer product 7. In the Fig. 8fIn the embodiment shown, the substrate 6 or the transfer product 7 is clamped over the first multifunctional roller 91 and the second multifunctional roller 92 in such a way that a flat printing surface is formed. The flat printing surface is preferably arranged perpendicular to the printing unit 8 or perpendicular to the ink ejection of the printing unit 8. Preferably, the first multifunctional roller 91 and the second multifunctional roller 92 are each rotatably mounted in two opposite directions of rotation, which depends on whether the substrate 6 or the transfer product 7 is being printed.

[0250] Fig. 9a and 9b each show a schematic sectional view of a system 4. The Figures 9a and 9b The systems shown essentially correspond to those shown in the Figures 6a and 6bshown systems, but with the difference that the transfer product 7 is conveyed in each case by a transfer product transport system 24 in the direction of the press nip, which is formed between the pressure roller 17 and the counter-pressure roller 18.

[0251] The Fig. 9a and 9b also show schematic sectional views of a multi-application device 2, which in particular further comprise a substrate 6 and a transfer product 7. Thus, in Fig. 9a and 9b also a (working) method of a multi-application device 2 is shown that the Fig. 9a and 9b shown variants.

[0252] Since only the transport path of the transfer product 7 in the Figures 9a and 9b of those in the Figures 6a and 6b Since the transport path of the transfer product 7 shown in the figure differs, only these modified transport paths are described to avoid repetition. The transport path of the substrate 6, however, is identical to that shown in the Figures 6a and 6b. The arrangement of the remaining components of the multi-application device 2 and the system 4 are identical to the arrangements in Fig. 6a and 6b .

[0253] This is how it works in Fig. 9aIn the variant of a (working) method shown, the transfer product 7 starts from a winding roller 12a and is guided via a tensioning system 16 along a multifunctional element 9 to a printing nip 10 formed between a printing unit 8 and the multifunctional element 9 for printing the transfer product 7. In this variant, the multifunctional element 9 comprises a first multifunctional roller 91 and a printing table 13 arranged above it. The transfer product 7 is then guided by the transfer product transport system 24 to a counter-pressure roller 18 and a pressure roller 17, with which the transfer product 7 is pressed onto a substrate 6. By means of a release roller 20, the transfer product 7 is separated again from the substrate 6, wherein the transfer layer remains on the substrate 6 in the previously printed areas. The transfer product 7 is then wound onto the winding roller 12b via a deflection roller 15 and a tensioning system 16.

[0254] Because the transfer product transport system 24 is arranged upstream of the counter-pressure roller 18, the transfer product 7 can be arranged in register with the substrate 6 using the transfer product transport system 24. The functioning of the transfer product transport system 24 is explained below in relation to the explanations of Figure 9b described.

[0255] At the Fig. 9b In the variant of a (working) process shown, the transfer product 7 is moved from a winding roller 12a, via a tensioning system 16, through a transfer product transport system 24 to a counter-pressure roller 18, where the transfer product 7 is pressed onto a substrate 6 by means of a pressure roller 17. Subsequently, by means of the release roller 20, as also in Fig. 9aAs shown, the transfer product 7 is separated again from the substrate 6, whereby the transfer layer of the transfer product 7 remains on the substrate 6 in the previously printed areas. The transfer product 7 is then wound onto the winding roller 12b via a deflection roller 15 and a tensioning system 16.

[0256] The material transport can be precisely controlled by the transfer product transport system 24 arranged downstream of the clamping system 16. The transfer product transport system 24 preferably controls the positioning in the press nip of at least one element and / or at least one layer on the transfer product 7 and of at least one element and / or at least one layer on the substrate 6 by means of the stretching of the transfer product 7 with precise register. The at least one element and / or the at least one layer on the transfer product 7 and / or on the substrate 6 is preferably already applied during the manufacturing process of the transfer product 7 or the substrate 6. In addition, optically detectable registration marks or register marks are applied to the at least one element and / or the at least one layer of the transfer product 7 or the substrate 6. These registration marks orRegister marks can be detected by a detection unit arranged in the transfer product transport system 24, and from this the position of the at least one element and / or the at least one layer on the transfer product 7 can be determined. With the aid of this data, a roller driven in the transfer product transport system 24 is accelerated or decelerated, whereby the transport speed of the transfer product 7 changes locally in relation to the global transport speed of the transfer product 7. Because the transfer product 7 is stretchable to a certain extent, the local transport speed of the transfer product 7 can be used to achieve accurate registration of the transfer product 7 to the substrate 6 or to the print on the substrate 6 and / or the at least one element and / or the at least one layer on the substrate 6.Such a driven roller can comprise one or more of the following elements, selected individually or in combination: roller with opposing press roller, roller with at least one or more segmented press rollers, or vacuum roller.

[0257] The transfer product transport system 24 can also have a tensioning system with which the stretching of the transfer product 7 can be further influenced. Thus, it is possible for the transfer product 7 to have a different transport speed upstream of the transfer product transport system 24 than downstream of the transfer product transport system 24. The stretching of the transfer product 7 thus enables the positioning of the transfer product 7 in register. List of reference symbols
