Description

Technical Field

[0001] The present invention relates to a printing device and a system having at least one such printing device. The present invention also relates to a printing method. The present invention also relates to a material web. Background Art

[0002] According to the prior art, corrugated board equipment and methods for producing corrugated board are well known through public prior use. The disadvantage is that, at the current state of the art, corrugated board sheets are always processed in which the printed samples are cut off due to the transverse cut or are incorrectly located at the transverse edge. This results in corrugated board waste, affecting the economy of the corrugated board equipment and also running counter to the concept of environmental protection. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide a printing device that overcomes the disadvantages of the prior art. In particular, a printing device should be achieved that is capable of processing corrugated board sheets of particularly high quality while minimizing corrugated board waste to the greatest extent. In addition, a corresponding system and method as well as a corresponding material web should be provided.

[0004] According to the present invention, this object is achieved by the features specified in independent claims 1, 4, 14, and 15. Advantageously, at least one position of at least one printed sample, in particular at least one position of each printed sample, can be locally moved in the corrugated board conveying direction and / or in the opposite direction of the corrugated board conveying direction or in the longitudinal direction of the web relative to the corresponding corrugated board sheet or the corresponding web. For example, for this purpose, at least one printed sample can be printed on the conveyed double-sided coated corrugated board web and / or on at least one material web for forming a double-sided coated corrugated board web at a slightly earlier or later time by means of the printing device. For example, the material web is a single-sided coated corrugated board web and / or at least one material web for forming the single-sided coated corrugated board web.

[0005] For example, the printing data comes directly or indirectly from an operating device, such as a control device, in particular a corrugated board equipment operating device, a production operating device, or similar devices. For example, the printing data relates to the position (longitudinal position / transverse position), size, and / or resolution of the printed sample and the content to be printed. The printing device is capable of receiving the printing data and accordingly printing the printed sample on the web to be printed.

[0006] For example, the double-sided coated corrugated board web is three-layer, five-layer, or seven-layer.

[0007] Advantageously, each local corrugated board web has printed samples, preferably a large number of printed samples. The printed samples can be the same or different. For example, the finished corrugated board is single-sided or double-sided printed.

[0008] Each corrugated cardboard sheet has two relatively arranged transverse edges, which are preferably parallel to each other and are formed by cross-cutting a double-sided coated (partially) corrugated cardboard web. The transverse edges preferably extend perpendicular to the corrugated cardboard conveying direction. Additionally, each corrugated cardboard sheet has two relatively arranged longitudinal edges, which are advantageously parallel to each other and extend in the corrugated cardboard conveying direction. The transverse edges and longitudinal edges of each corrugated cardboard sheet are preferably perpendicular to each other. Advantageously, the corrugated cardboard sheets have the same length in the corrugated cardboard conveying direction. They are preferably rectangular in shape.

[0009] The at least one device for processing at least one single-sided coated corrugated cardboard web advantageously has a corresponding corrugating device for forming the corrugated web, preferably has a gluing device for gluing the corresponding corrugated web, and preferably has a pressing device for pressing the corresponding covering web onto the mated and glued corrugated web.

[0010] The device for processing a double-sided coated corrugated cardboard web is advantageously designed as a heated pressing device. It preferably includes a heating table with heating elements and a pressing belt that surrounds guide rollers and together with the heating table forms a pressing gap. At least one single-sided coated and glued corrugated cardboard web and the covering web are guided through this pressing gap, where they are pressed against each other and glued together.

[0011] Advantageously, the printing device is designed as a digital printing device, especially an inkjet printing device. Advantageously, the printed samples are formed by ink, pigment or similar materials, especially by jetting these inks, pigments, etc. Preferably, the printed samples each have at least one digit, one letter, one photo, one graphic or similar content. Advantageously, they at least partially cover the printing surface of the web to be printed.

[0012] Advantageously, the slitting device is designed as a slitting / grooving device for longitudinally cutting and grooving a double-sided coated corrugated cardboard web. Advantageously, the device can cut the double-sided coated corrugated cardboard web while maintaining a certain distance from its longitudinal edges. The longitudinal edges of the corrugated cardboard sheets can be generated by this device. Advantageously, the slitting device has at least one slitter and a mating device associated therewith.

[0013] Advantageously, the cross-cutting device can form a cross-cut that extends across the entire width of the local corrugated cardboard web, thereby forming a corresponding transverse edge perpendicular to the corrugated cardboard conveying direction on the corrugated cardboard sheet. Advantageously, the cross-cutting device has at least one cross-cutting roller having at least one radially outwardly extending cross-cutting blade for completely transversely cutting the local corrugated cardboard web passing through the cross-cutting device. Preferably, the cross-cutting device has two cross-cutting rollers arranged in pairs, each of which can be rotationally driven about a rotation axis. The rotation axes are preferably parallel to each other. Advantageously, there is a roller gap between the cross-cutting rollers through which the local corrugated cardboard web passes. Advantageously, each cross-cutting roller has or is equipped with at least one cross-cutting blade. The cross-cutting blades of the cross-cutting rollers cooperate to cut the corresponding local corrugated cardboard web, thereby forming corrugated cardboard sheets downstream of the cross-cutting device.

[0014] The at least one cross-cutting blade preferably extends along the longitudinal axis or the axial direction of the rotation axis of the respective cross-cutting roller and extends circumferentially around the longitudinal axis or the rotation axis of the respective cross-cutting roller. Preferably, the cross-cutting blade follows a helical or arcuate path around the longitudinal axis or the rotation axis. For example, it is arranged helically on the housing surface of the corresponding cross-cutting roller to compensate for the inclined position of the rotation axis relative to the corrugated cardboard conveying direction. The corresponding local corrugated cardboard web can be cut perpendicular to the corrugated cardboard conveying direction by means of the at least one corresponding cross-cutting blade. Due to the inclined position of the rotation axis, continuous cutting of the corresponding local corrugated cardboard web can be achieved during the rotation of the cross-cutting roller. In this way, corrugated cardboard sheets of a specified length can be generated.

[0015] Advantageously, the operating device of the corrugated cardboard equipment is designed as a control and / or regulating device. Preferably, the operating device is electric or electronic. Advantageously, the operating device of the corrugated cardboard equipment forms a signal connection, at least sometimes directly or indirectly, with at least one printing device and / or cross-cutting device.

[0016] The signal connection described herein can be wireless or wired. Preferably, information or data can be transmitted unidirectionally or bidirectionally.

[0017] The terms "front", "rear", "downstream", "upstream" or similar expressions used herein refer specifically to the conveying direction of the corresponding web.

[0018] Further advantageous design options of the present invention are disclosed in the dependent claims.

[0019] The printing device according to dependent claim 2 can print the printing samples side by side, i.e., in rows. Preferably, it can also print the printing samples sequentially, i.e., in columns. Additionally, the printing device preferably enables at least one of the printing samples arranged side by side in a row to be arranged offset relative to the other printing samples arranged in that row.

[0020] In this way, the printing device can correspondingly adjust the at least one (longitudinal) position of at least one print sample on the width. According to the traditional method, the print samples arranged side by side are not misaligned with each other, that is, they are aligned with each other or accurately arranged in a row or a line. According to the present invention, the print samples are preferably arranged in layers or in a stepped manner. Advantageously, the print samples are arranged in a descending or ascending manner in the corresponding rows. For example, the offset between adjacent print samples arranged in a row is the same. Preferably, the print samples arranged side by side in the width direction of the local corrugated cardboard web are the same.

[0021] For example, the printing device according to dependent claim 3 can cooperate with the cross-cutting device for printing, or can be correspondingly operated, especially triggered. Preferably, in this way, corrugated cardboard sheets can be processed, and at least one print sample thereof is accurately aligned with at least one corresponding cross-cut or its transverse edge. It has been found that when cross-cutting a double-sided clad partial corrugated cardboard web to form corresponding (local) transverse edges or corrugated cardboard sheets, a cutting misalignment occurs in the width direction or the transverse direction of the local corrugated cardboard web. Due to this misalignment, it is particularly obvious in printing and will repeatedly cause corrugated cardboard waste. The main reason for this cutting misalignment when cross-cutting adjacent local corrugated cardboard webs arranged side by side is that the corrugated cardboard web is pulled in the corrugated cardboard conveying direction, so that the web tension gradually changes during the continuously timed cross-cutting process. According to the present invention, it has been found that by cooperating with the cross-cutting device or the cross-cutting process for printing, this misalignment can be compensated conveniently and with reliable function. Accordingly, the material web is printed.

[0022] It is advantageous if the printing mode of the printing device is such that at least one print sample is aligned with at least one cross-cut of the corresponding corrugated cardboard sheet.

[0023] Preferably, the printing device is correspondingly operated, especially triggered, for aligning the print samples. It is advantageous if the printing device has at least one printing device operation unit, especially a printing device control unit, or forms a signal connection with such a unit at least sometimes directly or indirectly.

[0024] Preferably, at least one cross-cut extends perpendicular to and / or along at least one adjacent / associated print sample.

[0025] The appearance of the finished corrugated cardboard is highly visually attractive. In this way, at least one cross-cut can be prevented from cutting at least one adjacent print sample, thereby causing at least one corresponding print sample to be incomplete or damaged.

[0026] Advantageously, the cross-cut detection device according to dependent claim 5 comprises at least one cross-cut detection machine, such as a cross-cut detection camera, a sensor and / or a laser, in particular a line laser. Advantageously, the cross-cut detection device operates in a non-contact or optical manner. For example, it is capable of independently detecting the cross-cuts or transverse edges of the generated corrugated cardboard sheets, in particular their position or orientation, in particular relative to the position or orientation of the corresponding corrugated cardboard sheets. For example, at least one cross-cut detection device can be moved in the width direction of the corrugated paper close to these corrugated cardboard sheets. For example, it forms a transverse motion system. Alternatively, the cross-cut detection device has, for example, a plurality of cross-cut detection machines, in particular arranged side by side, wherein, preferably, each partial corrugated cardboard web is matched with at least one cross-cut detection machine.

[0027] The cross-cut position analysis device according to dependent claim 6 is, in particular, an electric or electronic device. It is at least sometimes directly or indirectly signal-connected to the cross-cut detection device. The cross-cut position analysis device is particularly capable of analyzing the position of a cross-cut or a transverse edge of the corrugated paper, in particular relative to the corresponding corrugated cardboard sheet.

[0028] Preferably, the cross-cut position analysis device is an integral part of the corrugated board machine operating device. As an alternative, the two, for example, can also be designed independently of each other.

[0029] The embodiment according to dependent claim 7 is particularly cost-effective and functionally reliable. The cross-cut detection device can detect both the generated cross-cut and the cross-cut marking that triggers the cross-cutting process.

[0030] Advantageously, if the corrugated cardboard waste exceeds a limit value, corrugated cardboard is re-produced. Such a system is particularly reliable. Preferably, the limit value can be preset.

[0031] Preferably, the cross-cut detection device according to dependent claim 8 and the at least one printing unit are at least sometimes in direct or indirect signal connection with one another.

[0032] The empirical database according to dependent claim 9 or 10 will again result in the formation of a particularly efficient and environmentally friendly corrugated board equipment. It is advantageous if the empirical database forms a signal connection with the operating device, cross-cutting device, cross-cut detection device, and / or production control device of the corrugated board equipment, at least sometimes, especially directly or indirectly. At any time, it is preferably possible to update it in advance and / or in a timely manner, especially during the operation of the corrugated board equipment. It is advantageous if at least one detected or recognized actual value and / or conclusion can be saved in the empirical database. Advantageously, at least one of the conclusions can be used for subsequent orders or order combinations. Advantageously, a comparison is made with the empirical database before starting a new order. If at least one corresponding value already exists in the empirical database, advantageously, it will be transmitted as an initial parameter to at least one of the printing devices.

[0033] The design according to dependent claim 11 enables particularly high-quality corrugated board. Waste can be avoided.

[0034] At least one printing device according to dependent claim 12 can be adapted to the cross-cutting device, especially customized to the cross-cutting device. For this purpose, the printing device is operated accordingly, especially triggered. For this purpose, the cross-cutting device and at least one printing device form a direct or indirect signal connection with each other at least sometimes. For example, at least one printing device can be adapted to the type and / or design of the cross-cutting device, such as the type and / or design of at least one cross-cutting roller or at least one cross-cutting blade, and / or can be adapted to the orientation / arrangement of at least one cross-cutting device, etc. For example, at least one of the attributes is a personalized attribute of the cross-cutting device.

[0035] According to dependent claim 13, at least one printing device is, for example, a component of the corrugated board equipment. At least one printing device is especially integrated in the corrugated board equipment. As an alternative, at least one printing device and the corrugated board equipment are, for example, kept at a certain distance from each other, that is, arranged independently of each other in space. For example, they are arranged in different workshop areas, urban areas, cities, enterprises, locations, or similar places. For example, printing and corrugated board production are carried out separately in space and time.

[0036] The dependent claims and their embodiments also relate to preferred improvement designs of independent claim 14. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Figure 5 A block diagram is shown, which mainly shows Figure 4 The operation of the printing device and the cross-cutting device of the system shown in FIG. DETAILED DESCRIPTION

[0043] First, according to Figure 1 The corrugated board equipment comprises a device 1 for processing a single-sided coated corrugated board web.

[0044] The first material web 3 is fed to the device 1 for processing a single-faced coated corrugated board web by a first unwinding device 2. Advantageously, the first unwinding device 2 is designed as a splicing device, so that the first material web 3 is endless.

[0045] In the device 1 for processing single-face coated corrugated board webs, a first material web 3 is joined to a second material web 4 coming from a second unwinding device 5. Preferably, the second unwinding device 5 is designed as a splicing device so that the second material web 4 is endless.

[0046] In the device 1 for processing a single-face coated corrugated board web, a second material web 4 is passed between two adjacent corrugating rollers 6, 7, so that the second material web 4 is corrugated or fluted there. After passing through the paired corrugating rollers 6, 7, the second material web 4 is formed into a corrugated web.

[0047] Next, in the device 1 for processing single-face coated corrugated board webs, the corrugated tops of the second material web 4 are glued by means of a gluing device 8. The gluing device 8 comprises a glue roller which forms a gluing nip with the upper corrugating roller 6 and receives glue directly or indirectly, preferably in a metered manner, from a glue tank.

[0048] Next, in the apparatus 1 for processing a single-sided clad corrugated cardboard web, the second web 4 coated with glue is pressed against and joined to the first web 3 in a pressing gap between the press 9 and the upper grooved roller 6. For example, the press 9 is designed as a pressing roller. As an alternative, for example, the press comprises at least two reversing rollers and a pressing belt wound around them.

[0049] The single-sided clad corrugated cardboard web 10 is led out of the apparatus 1 for processing a single-sided clad corrugated cardboard web, which comprises the first web 3 and the second web forming the corrugations or the corrugated web 4.

[0050] The single-sided clad corrugated cardboard web 10 is conveyed to the preheating apparatus 11.

[0051] Furthermore, a third web 12 is conveyed from a third unwinding apparatus 13 to the preheating apparatus 11. Preferably, the third unwinding apparatus 13 is designed as a splicing apparatus such that the third web 12 is endless. The third web 12 forms the outer cladding web in the finished corrugated cardboard.

[0052] The preheating apparatus 11 has two heatable heating rollers 14 arranged one above the other, which are parallel to each other and extend horizontally. The single-sided clad corrugated cardboard web 10 and the third web 12 are partially wound around their respective heating rollers 14 in the preheating apparatus 11.

[0053] A digital printing apparatus 15 is arranged between the third unwinding apparatus 13 and the preheating apparatus 11, which prints the third web 12 on the printing side and is thus integrated into the corrugated cardboard equipment. In the finished corrugated cardboard, the printing side forms an exposed outer surface and is thus visible. For example, the digital printing apparatus 15 has a central roller or printing roller and a mating printhead apparatus. It can generate a print pattern 16 (see Figure 3 ). As an alternative, the digital printing apparatus 15 can also be placed at other positions. The corrugated cardboard equipment and the digital printing apparatus 15 form a system.

[0054] A gluing mechanism 17 with an applicator roller 18 is arranged downstream of the preheating apparatus 11, and the applicator roller directly or indirectly, preferably in a metered manner, obtains glue from a glue sump. The corrugated tops of the single-sided clad corrugated cardboard web 10 come into contact with the applicator roller 18, and are thus glued there.

[0055] The heating and pressing device 19 is arranged behind the gluing mechanism 17 and comprises a horizontal table 20 with a heating plate. Above the table 20, the heating and pressing device 19 has an endless pressing belt 22 that wraps around a guide roller 21. A pressing gap is formed between the pressing belt 22 and the table 20, through which the single-sided clad corrugated cardboard web 10 and the third material web 12 pass and are pressed against each other there. A double-sided clad three-layer corrugated cardboard web 23 is formed in the heating and pressing device 19. Thus, the heating and pressing device 19 forms a device for processing the double-sided clad corrugated cardboard web.

[0056] The slitting / cutting device 24 is arranged behind the heating and pressing device 19 and comprises a slitting unit 25 and a cutting unit 26. The slitting unit 25 respectively has two tool beds, which are arranged in a substantially mirror-symmetrical manner with respect to the double-sided clad corrugated cardboard web 23. On the pivotable tool beds, slitting tools are designed to be arranged on tool holders and to be movable transversely to the corrugated cardboard conveying direction 27 respectively, and they can each act on the double-sided clad corrugated cardboard web 23.

[0057] The cutting unit 26 has a tool bed on which rotary blades are designed to be arranged on tool holders and to be movable transversely to the corrugated cardboard conveying direction 27 respectively. When the blades cut into the double-sided clad corrugated cardboard web 23, the blades can each act on the double-sided clad corrugated cardboard web 23 and cooperate with a rotary drive brush roller arranged on the other side of the double-sided clad corrugated cardboard web 23. The cutting unit 26 can cut the double-sided clad corrugated cardboard web 23 into partial corrugated cardboard webs 28, which extend and move in the corrugated cardboard conveying direction 27 ( Figure 3 ).

[0058] The cross-cutting device 29 is arranged behind the slitting / cutting device 24 and comprises two rotatably drivable cross-cutting rollers 30 that are arranged in pairs and stacked and extend substantially perpendicular to the corrugated cardboard conveying direction 27. Each cross-cutting roller 30 extends horizontally and has a cross-cutting blade 31 that extends radially outwards. The cross-cutting blades 31 together effect a complete transverse cut of the partial corrugated cardboard web 28 passing through the cross-cutting rollers 30. In this way, cross-cuts 32 can be generated in the partial corrugated cardboard web 28 by the rotatably drivable cross-cutting rollers 30, and at the same time corrugated cardboard sheets 33 with corresponding transverse edges are formed ( Figure 3 ). The cross-cutting rollers 30 cut the entire partial corrugated cardboard web 28.

[0059] The cross-cut detection device 34 is arranged in a position adjacent to the downstream of the cross-cutting device 29, is associated with the partial corrugated cardboard web 28 and can detect the cross-cuts 32. The cross-cut detection device 34 extends transversely to the corrugated cardboard conveying direction 27 and passes through all the partial corrugated cardboard webs 28.

[0060] Furthermore, the conveyor belt 35 is arranged behind the cross-cutting device 29, on which the corrugated cardboard sheet 33 is guided to a stack 36.

[0061] Furthermore, the corrugated cardboard equipment has a corrugated cardboard equipment operating device 37, which is designed as a corrugated cardboard equipment control device and is capable of correspondingly controlling the corrugated cardboard equipment.

[0062] As Figure 2 shown, the corrugated cardboard equipment operating device 37 at least sometimes forms a signal connection with the cross-cutting device 29 and is capable of triggering the cross-cutting of the local corrugated cardboard web 28. In particular, the cross-cutting roller 30 can be rotationally driven accordingly.

[0063] Furthermore, the corrugated cardboard equipment operating device 37 at least sometimes forms a signal connection with the printing device operating unit 38, which is in particular designed as a printing device control unit. The printing device operating unit 38 is part of the digital printing device 15 or is designed to be independent of the digital printing device. The corrugated cardboard equipment operating device 37 can transmit corresponding control signals to the printing device operating unit 38, specifically regarding printing, especially regarding the printing target area or position. Conversely, the printing device operating unit 38 can correspondingly trigger the print head device of the digital printing device 15, thereby realizing the corresponding printing process.

[0064] The cross-cut detection device 34 at least sometimes forms a signal connection with the corrugated cardboard equipment operating device 37 and is capable of transmitting the position information of the generated cross-cut 32 to the corrugated cardboard equipment operating device 37. The corrugated cardboard equipment operating device 37 analyzes the rated cross-cut position and the actual cross-cut position. In particular, the operating device compares the two with each other.

[0065] If it is recognized that the deviation between the rated cross-cut position and the actual cross-cut position is too large, the corrugated cardboard equipment operating device 37 will trigger the printing device operating unit 38 to reduce the deviation by changing the position of the corresponding print sample 16. The digital printing device 15 then performs printing. The pre-printing or print sample 16 is formulated according to the speed change of the cross-cutting device 29 planned in advance. Here, the corrugated cardboard equipment speed forms the main body or main information.

[0066] In addition, the cross-cut detection device 34 at least sometimes forms a signal connection with the experience database 39 and is capable of transmitting the actual cross-cut (position) numerical values or information or conclusions to the experience database 39 for subsequent similar orders or order combinations.

[0067] The corrugated cardboard equipment operating device 37 also at least sometimes forms a signal connection with the experience database 39 and is capable of receiving the corresponding actual values or conclusions, which specifically relate to, for example, the set parameters or operating parameters corresponding to the corrugated cardboard equipment.

[0068] The experience database 39 and the printing device operation unit 38 form a signal connection at least sometimes, and if there are previous identical experience values existing or stored therein, it can, for example, provide the initial parameters of the digital printing device 15.

[0069] The corrugated board equipment operation device 37 continuously updates the experience database 39 in a timely manner.

[0070] In addition, the experience database 39 and the production control device 40 form a signal connection at least sometimes. The experience database 39 can transmit the corresponding experience values to the production control device 40.

[0071] Conversely, the production control device 40 can receive the corresponding actual values from the experience database 37.

[0072] As Figure 3 shown, for the local corrugated board web 28, the transverse cuts 32 are arranged offset from each other in the width direction thereof, that is, perpendicular to the corrugated board conveying direction 27 of each local corrugated board web 28. At the same time, they are offset from each other in the corrugated board conveying direction 27, that is, in the longitudinal direction of the corresponding local corrugated board web 28. For example, the offset of the corresponding transverse cuts 32 generated by the transverse cutting device 29 is due to the transverse cutting roller 30 being arranged inclined, especially slightly inclined, with respect to the conveyed double-sided coated corrugated board web 23, so as to substantially compensate for the cutting offset caused by the rotating transverse cutting roller 30. Since the transverse cutting blade 31 follows an arcuate path around the transverse cutting roller 30, a scissor-type transverse cut is formed. During the scissor-type transverse cut, the transverse cutting blade 31 briefly jams the double-sided coated corrugated board web 23 or the local corrugated board web 28 at the current cut. The uncut surface is instantaneously pushed away from the rated cutting position, resulting in an offset across the entire width of the double-sided coated corrugated board web 23. As previously mentioned, the offset of the corresponding transverse cuts 32 generated by the transverse cutting device 29 is also, for example, due to the local corrugated board web 28 being pulled during conveyance and the corresponding web tension changing, especially suddenly, due to the continuous transverse cutting of the local corrugated board web 28. As Figure 3 shown, each transverse cut 32 is designed to be layered or stepped.

[0073] According to Figure 3 , the double-sided coated corrugated board web 23 has two opposite longitudinal edges 41 and 42, which are parallel to each other and parallel to the corrugated board conveying direction 27.

[0074] For the first local corrugated board web 28a adjacent to the first longitudinal edge 41 ( Figure 3 , the leftmost), each local transverse cut 32a generated here is advanced compared to each local transverse cut 32b of the second local corrugated board web 28b arranged adjacent to the first local corrugated board web 28a.

[0075] For the second partial corrugated cardboard web 28b, each locally generated transverse cut 32b is advanced compared to each locally generated transverse cut 32c of the third partial corrugated cardboard web 28c arranged adjacent to the second partial corrugated cardboard web 28b.

[0076] For the third partial corrugated cardboard web 28c, each locally generated transverse cut 32c is advanced compared to each locally generated transverse cut 32d of the fourth partial corrugated cardboard web 28d arranged adjacent to the third partial corrugated cardboard web 28c and adjacent to the second longitudinal edge 42.

[0077] The locally generated transverse cuts 32a, b, c, d of each partial corrugated cardboard web 28a, b, c, d are parallel to one another. The locally generated transverse cuts 32a, b, c, d formed by the cutting process respectively form transverse cuts 32 in the partial corrugated cardboard webs 28.

[0078] The partial corrugated cardboard webs 28 are separated from one another by longitudinal cuts 43 formed by the longitudinal cutting unit 26. The generated longitudinal cuts 43 extend in the corrugated cardboard conveying direction 27 and are parallel to one another. In this way, the longitudinal edges of the partial corrugated cardboard webs 28 are formed. They are perpendicular to the locally generated transverse cuts 32a, b, c, d.

[0079] For example, as an alternative, a design without a transverse cut detection device 34 can be used. For example, the corresponding conclusions can equally well be drawn from the experience database 39, from historical data, expert knowledge or similar sources.

[0080] The following refers to Figure 4 、 5 Describe the second embodiment. Identical components have the same reference signs as in the previous embodiment, and reference is hereby expressly made to the description in the previous embodiment.

[0081] According to this embodiment, the digital printing device 15 is arranged independently of the (actual) corrugated cardboard equipment. The unwind device 48 is placed in front of the digital printing device 15 and is designed, for example, identically to the third unwind device 13. In use, the unwind device 48 unwinds the material web 12, which passes through the digital printing device 15 for printing.

[0082] The rewind device 49 is placed behind the digital printing device 15 and comprises a rotatably supported rewind roller for rewinding the material web 12, in particular the printed material web 12. The rewound material web 12 can be transferred to the corrugated cardboard equipment and can be used there as the third material web 12.

[0083] Here, the cross-cut detection device 34 forms a signal connection with the production control device 40, the corrugated board equipment operating device 37, and the corrugated board equipment experience database 45 at least sometimes, and is capable of transmitting corresponding cross-cut information to them. The production control device 40 is used for the production control of the corrugated board equipment, and is capable of sending corresponding conclusions to the corrugated board equipment experience database 45 and the corrugated board equipment operating device 37, and receiving actual values from them.

[0084] The corrugated board equipment operating device 37, in turn, is capable of correspondingly triggering the cross-cutting device 29. Preferably, it is also capable of performing the analysis of the nominal and actual printing positions.

[0085] The production control device 40 of the corrugated board equipment forms a signal connection with the production control device 46 of the printing device at least sometimes. It is capable of transmitting the production information of the corrugated board equipment to the production control device 46 of the printing device, and conversely, the production control device 46 of the printing device is capable of receiving this information. The production control device 40 is capable of receiving corresponding printing information from the production control device 46 of the printing device. In particular, the production control device 40 of the corrugated board equipment can transmit corrugated board equipment parameters for a specific order, such as the planned production speed, at least one cross-cutting device specification, and / or cutting accuracy. Conversely, the production control device 46 of the printing device can receive these parameters. For example, it can transmit material web roller information, such as incorrect printing positions, to the production control device 40 of the corrugated board equipment. Preferably, the production control device 40 and the production control device 46 of the printing device are spatially arranged separately from each other. Preferably, two-way data or signal transmission can be carried out between them.

[0086] The production control device 46 of the printing device forms a signal connection with the printing device operating device 38 at least sometimes, and is capable of providing corresponding information for the printing device operating unit 38.
