Description

Technical Field

[0001] This invention relates to an apparatus for providing sheet-like substrate segments and a machine and method for processing and / or handling web-like substrates. Background Technology

[0002] WO2020 / 064230A1 discloses a machine for processing and / or handling web-shaped substrates, wherein a substrate roll is unwound at the inlet side and conveyed downstream of a transverse cutting device, where the substrate is transversely cut into substrate segments. These segments are conveyed to an inspection station and, at the downstream end of the machine, placed on different stacks in a multi-stack removal manner according to the inspection results. In one embodiment, the substrate strip is also printed on the upper side of the substrate web prior to transverse cutting, wherein the substrate segments resulting after transverse cutting are printed once or multiple times downstream on the same substrate side by one or more printing devices.

[0003] DE10103040A1 discloses an apparatus for forming a series of lower stacks of individual sheets, which are fed to a placement table of a downstream printing press. Here, the apparatus includes a holding device and a feeding device on the inlet side, by means of which the holding device holds and unwinds the paper roll, and by means of which the feeding device feeds the paper strip through the placement table to a cross-cutting machine. The resulting individual sheets are fed to the placement table of the printing press via two conveyor belts and a folding device.

[0004] A method for producing printed sheets of paper from web material is disclosed in EP3878652A1, in which the web material is coated with an adhesive and provided with a film before the web material is cut into sheets online and printed.

[0005] DE102009061056A1 relates to a roll-to-roll printing press having two inkjet printing units for two-sided inkjet printing, wherein a dryer is disposed after each inkjet printing unit along the web path. The inkjet printing units and dryers then undergo reprocessing, in which the web is folded, cut into sheets, and the sheets are finally fed to a take-up module. Here, at the inlet side of the take-up module, multiple sub-webs obtained through longitudinal sections can be stacked on top of each other via guide bars.

[0006] CN101524912A discloses a roll printing press with different interchangeable printing and processing assemblies, the printing and processing assemblies having, for example, different printing methods and die-cutting devices, wherein the printed and processed web is wound again at the exit side.

[0007] CN105196696A discloses a printing press having multiple assemblies, particularly an uncoiler, a printing unit, a dryer, a cooling and buffering unit, and a longitudinal cutting unit. These assemblies are controlled by a programmable control device.

[0008] DE202012102681U1 discloses a roll printing machine for printing material webs, particularly those made of cardboard, unwound from a roll. The roll printing machine has a printing unit and a coating unit disposed downstream of the printing unit, wherein the printed and coated webs are rolled up again downstream in one embodiment or cut into blocks by a transverse cutter and stacked by a paper pusher in another embodiment. Summary of the Invention

[0009] The object of this invention is to provide an apparatus for providing sheet-like substrate segments and a machine and method for processing and / or handling web-like substrates.

[0010] A particular advantage of this invention is that it can provide sheet-like substrates, manufactured by means of equipment or machines from a web-like substrate and further processed, for example, by printing, the substrate undergoing, for example, online finishing or pretreatment, such as large-area or even full-surface fluid application, before cutting. The finishing or pretreatment by fluid application is carried out by a suitable device, such as an inking device, by which fluid, for example in the form of a liquid or paste substance or mixture of substances or fluidized powder, can be applied to the substrate.

[0011] The solution according to the invention is particularly advantageous in applications where a barrier layer is required on a first side of a substrate, such as on the back side of a printed product or the inside of a hollow body, to prevent adjacent gaseous, liquid, or paste-like media from entering or penetrating the substrate material. In this case, the applied fluid, especially after drying and / or hardening, forms a barrier layer in the form of a coating. This application is not only, but particularly, seen in the packaging field, especially in the food industry. Such a barrier layer can be provided using the solution according to the invention in a simple manner, unlike the conventional method of achieving a barrier layer through lamination with a film. In the food field, decorative media are considered, for example, water-based paints permitted by the food industry, or liquid plastics, such as polyurethane or casting resins. As an alternative to a paint or plastic layer applied, for example, in the form of a coating, the fluid can be applied, for example, by impregnation, at least partially flushed into the substrate. In a particularly preferred machine, the application of the barrier layer on one side (e.g., the inner side of the product afterward) or at least over a large area and the printing of the image on the other side (e.g., the outer side of the product afterward) can be performed online, i.e., in a continuous workflow.

[0012] Advantageous apparatus for providing sheet-like substrate segments, particularly those with a barrier layer on the back or subsequent inner side, includes: an unwinder for feeding the web-like substrate at the inlet side; two inking devices formed by a coating device in the substrate path of the web-like substrate between the unwinder and a cross-cutting device, for coating the web-like substrate with a coating to form a barrier layer on the same first side; a drying device between the cross-cutting device and a first coating device viewed from upstream and / or a drying device in the substrate path between the two coating devices; and a cross-cutting device that can cut the web-like substrate into sheet-like substrate segments downstream of the coating and provide the substrate segments at their outlet for further processing or output to a delivery unit. Preferably, no other inking device is provided between the unwinder and the transverse cutting device in the substrate path segment, except for the inking device that applies the barrier layer on the first side, so that only a single sheet of substrate with a barrier layer is provided behind the transverse cutting device for subsequent printing but for back-side pretreatment.

[0013] By applying at least two coats of paint, along with intermediate drying and / or post-drying, in this embodiment of the device, the thickness required for the application according to the invention can be achieved particularly well, thereby providing the possibility of replacing laminated plastic films.

[0014] In an embodiment of the invention, a machine for processing and / or handling web-like substrates includes a first machine component and a second machine component directly connected to the first machine component. The first machine component has: an unwinder for feeding the web-like substrate at an inlet side; at least one inking device for fluid-inking the web-like substrate on a first side to form a barrier layer; and a transverse cutting device for cutting the web-like substrate into sheet-like substrate segments. The second machine component has a substrate path that guides substrate segments through the substrate path of the second machine component. The substrate segments exiting the transverse cutting device are transferred online onto the substrate path, and the substrate path is guided at the exit side to a receiving device, which can accommodate processed and / or treated substrate segments. The machine includes an accelerated drying and / or hardening device, referred to simply as a drying device, between the transverse cutting device and the single or first inking device viewed from upstream in the substrate path of the first machine component. One or more sheet-fed printing devices and / or one or more sheet-fed coating devices are provided in the substrate path between the transverse cutting device and the receiving device. Through the printing devices and / or coating devices, the substrate segments can be printed with printed images or coated with paint on their second side opposite to the first side.

[0015] To produce substrate segments having such a layer, especially a barrier layer, the web-shaped substrate is unwound from a substrate roll storing the substrate and has a barrier layer formed on a first side, either the back or the inner side, in subsequent products. This is done by applying a fluid to the first side of the web-shaped substrate, which is formed on the back or the inner side, particularly in subsequent products, one or more times by one or more inking devices to form a barrier layer with a total layer thickness of at least 5 μm. Downstream of the inking devices, the web-shaped substrate that has been fluid-inked is at least surface-dried and / or hardened at least in the area where the fluid was inked by at least one device for accelerating drying and / or hardening. The substrate that has been fluid-inked with the fluid that has at least surface-dried and / or hardened is cut into substrate segments by a transverse cutting device, and the substrate segments are assembled into one or more stacks in a delivery device downstream.

[0016] Preferably, a layer, such as an ink layer or especially a varnish layer, with a thickness of at least 5 μm, and particularly at least 8 μm, is produced on the first side by at least one, i.e., by one or more such inking devices. The thickness of the applied and dried layer can be up to 12 μm, and particularly up to 15 μm.

[0017] However, the solution according to the invention can also be advantageously used in other improved applications, such as on the back of a product or, in the case of a device, on the front of a product or, for example, on a coating intended to provide protection for the surface of a substrate, to reinforce the substrate, or to provide optical or tactile effects over a large area or across the entire surface.

[0018] Although the equipment for supplying the beautified substrate sheet to the stacking or storage device may be constructed simply as a "vertical" machine with means for beautifying and cutting the substrate sheet, in a particularly advantageous improvement of the machine, such as a combined machine, there is at least one additional means downstream of the transverse cutter for processing, in particular printing and / or coating, the substrate sheet (especially at least on the second substrate side opposite to the beautification or coating described above), through which one or more additional processing steps, particularly color printing, can be performed online in the machine downstream of the transverse cutter.

[0019] Here, the terms “first” side and “second” side as the base material are used only for better conceptual distinction and can also be chosen in reverse order.

[0020] In one embodiment of the device or machine, at least one inking device is arranged in the substrate path and / or the substrate path guide from the at least one inking device to the transverse cutting device is configured such that the substrate applied by the at least one inking device on a first side exits the transverse cutting device pointing downwards on the first side, i.e., the side with the inked fluid.

[0021] In one of the advantageous embodiments of the machine described above, for example as a combined machine, a printing press, particularly a sheet-fed printing press, is designed with one or more processing units designed as printing devices and a coating section, particularly a web coating section, arranged upstream. Thus, the printing and / or painting of the sheet and the finishing or coating of the web-like substrate are carried out online. Individual or combined assemblies for finishing can be selectively inserted into the substrate path between the belt feeder arranged on the inlet side and the downstream printing and / or painting units, and can be removed again, in advantageous corresponding inking and drying units. Therefore, the operation of the machine with or without such finishing can be achieved without unnecessary "idling" through such a device. In a variation of this, such assemblies can not only be inserted and removed, but can also be replaced by other types of assemblies or supplemented by other assemblies.

[0022] Of course, optional and / or supplementary insertions and removals also apply to those cases of the so-called stand-alone implementation described above, that is, in implementations without one or more processing devices located behind the transverse cutter, so as to provide, for example, only single sheets of paper from the web-forming machine.

[0023] In a particularly preferred embodiment, the inking device for beautification can be configured to be suitable for application over a large area or preferably the entire surface, such as a printing assembly or, in particular, a painting device for coating a substrate over a large area or the entire surface.

[0024] In this document, the term "full surface" should be understood as continuous application on a surface of a substrate occupied by at least one or more sheets obtained from the substrate. "Large area printing" should be understood as printing on the entire surface in the foregoing sense, however, ink is applied to at least 80% of the aforementioned area, and / or one or more individual area regions, for example, up to 10 area regions per sheet, which remain empty within one or more sheets in the corresponding sheet, for example, in the area of ​​the bonding portion in a later product, and / or for example, occupy less than 20% of the total area of ​​the corresponding sheet.

[0025] Although an inking mechanism can be configured in principle as an inking device with any structure, in a particularly advantageous embodiment it is configured as an inking mechanism, especially a varnishing device, that operates according to letterpress printing methods, especially flexographic processes, and has a letterpress printing plate, such as a so-called varnishing plate.

[0026] In the case where multiple inking devices for finishing are located upstream of the transverse cutting machine, it is preferable to provide at least one device for accelerating drying and / or hardening in the substrate path between every two finishing devices. Attached Figure Description

[0034] Figure 6 An enlarged view of an inking mechanism with an anilox roller and a chamber doctor blade operating according to a flexographic process is shown. Detailed Implementation

[0035] An apparatus for providing sheet-like substrate segments or a machine for processing and / or handling web-like substrates S, such as substrate webs, includes, at the inlet side, means for feeding the web-like substrate S, such as the substrate S to be unwound from the substrate roll 11, such as a so-called unwinder 01. In a particularly advantageous embodiment, the unwinder is configured as a rewinder for "flowing," i.e., uninterrupted rewinding (e.g., for all embodiments of the illustrated machine in...). Figure 3 The example shown is an advantageous improvement.

[0036] With this device or machine, the web-shaped substrate S on the inlet side can be processed and / or treated on the outlet side as a sheet-like substrate, especially as an intermediate product of the final product manufactured from the sheet-like substrate S through further processing.

[0037] Downstream of the substrate path, still in the form of a web-like substrate S, the device or machine includes at least one substrate processing device in the form of an inking device 02; 02', particularly an inking mechanism, which, on a first side, uses a fluid to coat or ink the web-like substrate S. Here, fluid application, especially over a large area or even the entire surface, is performed online before cutting; that is, the fluid is applied, for example, in the form of a liquid or paste material or a mixture of materials or a fluidized powder. Here, the inking device 02; 02' is preferably designed as a printing device or, particularly, a coating device.

[0038] The adjustment of the printing or coating apparatus is preferably implemented in the structural form of a flexographic printing apparatus, a gravure printing apparatus, or a screen printing apparatus, and particularly preferably in the form of a flexographic printing apparatus or a coating apparatus, hereinafter also referred to as a flexographic apparatus. This approach is applicable to all implementations of the machine, for example... Figure 2 , Figure 3 and Figure 5 The improved solution is shown as a particularly preferred embodiment. Here, in Figure 2 The image exemplarily illustrates a flexographic device in the form of an open system, while... Figure 3 as well as Figure 5 The example shown is of the form, for example, in Figure 6 The enlarged view shows the flexographic plate device of the closed system, but... Figure 2 The open-type flexographic plate device illustrated in the example can be used in... Figure 3 or Figure 5 Instead of the closed system exemplified in the example, and conversely, in Figure 3 and Figure 5 A closed system in the middle can be achieved through... Figure 2 The open flexographic plate device shown in this example is used instead.

[0039] exist Figure 1 and Figure 4The inking device 02; 02' shown is also exemplary for all illustrated variations of the machine, replacing the design of an inking mechanism in the form of a gravure printing apparatus. Specific illustrations of advantageous alternatives applicable to all illustrated variations as screen printing apparatuses are omitted here. Essentially, the inking device 02; 02' can also be used as an offset printing apparatus or an inking device 02; 02' otherwise suitable, while ensuring a minimum thickness of fluid ink application, for example, at least 5 μm, and especially at least 8 μm. In this case, if better variability can be achieved, for example, in the uninked areas on the substrate S (because, for example, glue will be applied in a subsequent process), an inking device 02; 02' operating according to a non-impact method or without a printing plate can be considered. Although different types can theoretically be combined in the case of multiple inking devices 02; 02', it is preferred to use inking devices 02; 02' of the same type.

[0040] By utilizing the preferred structural form of the inking mechanism, especially the coating device, in the form of a letterpress printing apparatus, a gravure printing apparatus, or a screen printing apparatus, a relatively thick fluid layer can be applied. This is particularly suitable for embodiments in the form of letterpress printing apparatus, especially flexographic apparatus, or particularly suitable for coating devices 02; 02' operating according to screen printing methods, wherein, especially in the latter case, the required high fluid thickness can be applied in a single application if necessary.

[0041] The inking mechanism, preferably constructed in the manner of letterpress printing rollers, particularly flexographic devices, includes an inking cylinder, such as a plate cylinder 24, especially a coating cylinder, which circumferentially carries a letterpress printing plate, such as a so-called coating plate or coating board. The inking cylinder, especially the coating cylinder, engages with another cylinder, such as an impression cylinder 28, via a substrate web to be inked, and forms an inking area therewith. The inking or coating cylinder receives fluid, especially varnish, through one or more rollers. In embodiments of flexographic devices, also known as open structures, the inking or coating cylinder receives fluid, for example directly or indirectly, from an immersion roller, such as a chrome roller (not shown), which is immersed in a fluid container, such as an ink fountain. In a preferred embodiment, also known as a closed structure, the inking or coating cylinder receives fluid through an anilox roller 29, which engages upstream on the anilox roller side with a doctor blade 31, especially a chamber doctor blade (see, for example, [link to relevant documentation]). Figure 6 To collect any excess or discharged fluid, a collection container 32 can be provided below the chamber scraper. The paint and impression cylinders can be brought into contact with each other via the substrate web by adjusting the first actuator 33 of the paint cylinder and / or by adjusting the second actuator 34 of the impression cylinder 28.

[0042] To provide a large-area barrier layer or visual effect, the inking device 02; 02', or the printing plate or especially the varnished printing plate received on the printing cylinder 24, for example, is specifically configured, in contrast to printing devices used for finely structured images, graphics, or alphanumeric characters, to: apply fluid to the substrate S on at least one surface, either entirely or over a large area, such that the application occurs on at least the entire surface of the substrate S, or at least 80% of the surface obtained from the printed sheet from the substrate, or at least on the surface corresponding to that surface. For example, if the printed sheet on the relevant side needs to be completely, i.e., uninterruptedly protected or effective, then the entire surface is important. Inking with notches can be particularly advantageous, for example, in packaging printing, for example, for creating three-dimensional hollow bodies in the area of ​​the adhesive position after folding.

[0043] To achieve one of the aforementioned full-surface or large-area fluid inking, the inking device 02; 02' is formed, for example, by a printing or painting device. The printing or painting plate, positioned on a printing cylinder 24 that indirectly or directly cooperates with the substrate, has printing subjects (i.e., the distribution of printed area regions) on the entire surface in terms of printing width and printing length corresponding to one or more printed sheets, or printing subjects with less than 20% of the area of ​​the one or more printed sheets that are not printed. Here, based on the frequent similarities between printing and painting devices, the inking device 02; 02' is also implemented as a painting device. For simplicity, the printing subject should be understood as the distribution of the surface area to be inked by the fluid.

[0044] As a fluid used for beautification or treatment, it may be provided as a water-based paint (e.g., a water-based paint permitted in the food industry) or a liquid plastic (e.g., polyurethane or casting resin). However, instead of paint or plastic provided, for example, in the form of a coating, in another embodiment or for another application as a fluid, a fluid that is at least partially deposited in the substrate may be provided (e.g., as an impregnating agent).

[0045] The substrate transport direction T, viewed downstream of the inking device, particularly in the substrate path of the web-shaped substrate S, downstream of the single or final inking device 02; 02, provides means for cutting the web-shaped substrate into substrate segments S', such as a transverse cutting device 04 or a so-called cutting mechanism. The web-shaped substrate S, which is fluid-inked and preferably at least surface-hardened, is cut into sheet-like substrate segments S' by the cutting device or cutting mechanism. In a preferred embodiment, the transverse cutting device 04 is configured to cut substrate segments S' of different desired segment lengths. In the substrate path of the web-shaped substrate S or in the substrate path provided upstream of the transverse cutting device 04, multiple inking devices 02; 02' that ink the same substrate side can be provided, for example, different or preferably the same type (e.g., in embodiments of the entire description of the machine, in...). Figure 2 , Figure 3 and Figure 5 The advantageous improvement shown in the example is of the same type for the two inking devices 02, 02', and is exemplarily a flexographic coating device, i.e., a flexographic printing device or in particular a flexographic coating device.

[0046] The substrate is formed, for example, from a material based on or containing a honeycomb structure, in a single or multiple layer, such as paper, paperboard or cardboard.

[0047] The following embodiment of the machine is particularly advantageous, in which the machine has at least one means for accelerating drying and / or hardening, such as at least one drying device 03; 03' longitudinally, between the means for feeding the web-shaped substrate S at the inlet side and the transverse cutting device 04. Preferably, at least one such means is arranged on the side of the substrate path facing the first side (i.e., upstream, especially in the processing and / or handling steps directly upstream), or facing the side of the substrate path directly upstream through the aforementioned inking device 02; 02' for fluid inking. Thus, the beautifying inked portion, especially the barrier layer, is also fixed and, for example, dried and / or hardened, at least on the surface, before subsequent mechanical loading. In an advantageous improvement, multiple such drying devices 03; 03'; 03'' are provided downstream of the aforementioned or one of the same inking devices 02; 02', on the first side of the freshly inked substrate path (e.g., for the embodiment described in the entire description of the machine, as an example of an advantageous improvement). Figure 1 As shown in, Figure 2 Shown on the right and in Figure 4 Two drying devices are shown in the diagram, and... Figure 2 , Figure 3 China and in Figure 5The example refers to three devices for accelerating drying and / or hardening that are themselves connected to the same inking device 02; 02', such as drying device 03; 03'; 03''.

[0048] In addition to one or more of the aforementioned devices for accelerating drying and / or hardening, at least one additional device for accelerating drying and / or hardening, not shown herein, may also be used on the second side of the web-shaped substrate S opposite to the side with fresh ink and fluid, particularly at least one drying device, in the substrate path.

[0049] At least one additional device for accelerating drying and / or hardening is particularly advantageous when combined with an improvement on the machine (not shown), wherein at least one additional inking device (not shown) is arranged upstream of the transverse cutting device 04 in the substrate path, on the side of the substrate path located on the second side of the substrate S, that is, on the side opposite to the first side of the substrate S where at least one inking device 02; 02' is applied once or multiple times. Such inking on the second side of the substrate S can, for example, be used for beautification, which may also form a fluid barrier on that side or, for example, form a large area or an entire surface of background color.

[0050] These, or at least one, several, or all of the aforementioned drying devices 03; 03'; 03'' can advantageously operate non-contactly, i.e., without contact with the substrate S, and are preferably configured to operate based on radiation, such as IR or UV radiation, utilizing one or more corresponding radiation sources 19, or alternatively configured as dryer elements operating based on hot air. One or more of these drying devices 03; 03'; 03'', which may not be longitudinally separated from each other in the substrate path by the inking devices 02; 02', can be housed in an assembly called a dryer, such as a radiation dryer or a hot air dryer, or in a combination of multiple such drying devices 03; 03'; 03''.

[0051] On the exit side of the transverse cutting device 04, substrate segments S' that are at least unilaterally beautified or, for example, once or multiple times, inkd with fluid and preferably at least have their surfaces dried or hardened are indirectly or directly fed to the receiving device 06, such as a stacking receiver, via one or more suitable first feeding devices 12 as sheet-like substrates S' or simply sheet-like substrates. In the receiving device, the sheet-like substrate segments S' obtained in the machine through processing and / or manufacturing are collected, in particular, assembled into stacks 13.

[0052] For cases where substrate sheets are further processed into intermediate products in a separate machine, such as a stand-alone machine, or for cases where in-line processing is carried out on a second side of the substrate, such as the outer side of a subsequent product, in the same web processing and / or processing machine, such as in a single or multiple printing and / or coating process, the arrangement of the machine or at least one inking device 02; 02' and the design of the substrate path are particularly advantageous, wherein the substrate emerges from the transverse cutting device 04, wherein the first side that is inked or beautified points downward, i.e., the side that is fluidly inked or beautified by one or more inking devices 02; 02', and / or the side that forms the inner surface in a later product, such as a cavity, points downward. Thus, the substrate sheet exists as substrate segments S' after transverse cutting, which can be stacked downward with their beautified or protected by a barrier layer first side down and processed once or multiple times, such as printing and / or coating, on their upper side in a subsequent working step in another machine or advantageously directly and immediately afterward with their first side down.

[0053] Therefore, in an advantageous first embodiment, the inking devices 02; 02' for inking the first side can be arranged in the substrate path such that the corresponding inking devices 02; 02' (especially in the case where the substrate path is mostly horizontal at the inking location), with the inking roller located below the substrate path, or (especially in the case where the substrate path is mostly vertical at the inking location), are located on the substrate path on the side opposite to the device for inlet-side feeding, and / or the substrate S guided by the inking device on the substrate path is printed on the lower side, that is, on the downward-pointing side of the substrate S in the region of the inking location and / or on the side opposite to the device for inlet-side feeding. However, here, the downward-pointing or lower side does not necessarily extend parallel to the horizontal line, but may also extend obliquely to the horizontal line.

[0054] In an optional advantageous embodiment, the inking devices 02; 02' for inking the first page are arranged in the substrate path such that the corresponding inking devices 02; 02' (particularly in the case where the substrate path is substantially horizontal at the inking location, i.e., inclined at <45° relative to the horizontal line) are located on the substrate path above the substrate path, or (particularly in the case where the substrate path is substantially vertical at the inking location, i.e., inclined at >45° relative to the horizontal line) are located on the side of the substrate path facing the device for feeding at the inlet side, and / or the substrate S guided by the inking device on the substrate path is printed on its upper side. Here, pointing upward or upper side does not necessarily have to be parallel to the horizontal line, but can also extend obliquely relative to the horizontal line. In a preferred improvement, not only can it be, but preferably can it be combined with this alternative embodiment, in the substrate pad between the single or downstream final inking device 02; 02' and the transverse cutting device 04, a rod-type flipping device 26 can be provided, for example, having two flipping rods, particularly two flipping rods extending at right angles to each other. With such an arrangement, the first side of the substrate web, which enters from the upper side at the entrance, turns downward, while conversely, the side previously below, for example, turns upward. Alternatively, in order to perform flipping in the substrate path, a sheet-flipping device, such as a flipping roller (not shown here), can be provided between the transverse cutting device 04 and the paper receiving device 06, particularly upstream of the first printing or coating device 07; 08; 09.

[0055] Here, the inking device 02; 02', such as the aforementioned printing plate cylinder 24, together with the fluid guiding part or fluid inking part of the fluid inking mechanism or the non-impact printing device for pressureless operation, is located below the aforementioned position of the inking device 02; 02'. This is independent of whether a support (e.g., an impression cylinder or a supporting guide, or even another, for example, a second side with the same or another fluid inking printing device or coating device guiding the fluid) is provided on the opposite side of the substrate path.

[0056] After cross-cutting, the substrate sheet, particularly beautified and / or inked in the manner described above, is first fed by one or more of the aforementioned take-up devices 06, or, in an alternative embodiment of the machine, by at least one first feeding device 12, to one or more additional inking devices, such as one or more printing devices, particularly sheet-fed devices, for further processing of the substrate, now in sheet-fed form, particularly on its second side. The substrate sheet is then conveyed, preferably via a series of conveying cylinders and impression cylinders, through one or more additional inking devices and possibly between them, via a continuous sheet-fed transfer from cylinder to cylinder. In embodiments of a machine having one or more printing devices subsequently positioned after the cross-cutting device 04, the machine may also be referred to as a printing press, particularly a sheet-fed printing press, which includes a beautification section arranged upstream of at least one printing device, having at least one of the aforementioned inking devices 02; 02' and at least one of the aforementioned accelerated drying and / or hardening devices.

[0057] The first feeding device 12, located directly behind the transverse cutting device 04, is preferably constructed as a belt table, particularly a suction belt table, through which the substrate sheet S is conveyed to the sheet feeder of the first or only printing or painting device in the substrate path for further processing, and directly to the receiving device 06 for cases where further processing is not required online, or conveyed to the second feeding device 18 included in the receiving device 06, for example, to the surrounding chain gripper system, via a transfer unit provided if necessary. Preferably, the first feeding device 12 is also configured, for example, to compress the incoming substrate segments S' into a stacked flow, particularly for the first case (i.e., with further processing), where each substrate segment S' is stacked at its rear end with the front end of the corresponding subsequent substrate segment S', and / or for the second case (i.e., directly fed to the receiving device 06), where the corresponding substrate segment S' is stacked at its rear end with the front end of the corresponding subsequent substrate segment S'.

[0058] In a favorable improvement, downstream of the transverse cutting device 04 and upstream of the paper receiving device 06 in the substrate path, or, if necessary, upstream of the first or only printing or painting device in the subsequent substrate path, an additional feature is provided, for example, in... Figure 1 The substrate turnout 17, which is shown and labeled by way of example for other embodiments, can lead out, for example, a defective sheet of paper that is deemed poor from another substrate path.

[0059] Not only, but especially in conjunction with a roll changer constructed for smooth roll changes, in an advantageous embodiment, a so-called web storage 27 can be provided between the device for inlet-side feeding and the single or downstream first inking device 02; 02', for example, a substrate path with variable loop lengths over multiple web loops (e.g., for the entire embodiment of the machine shown in the variants) Figure 3 The example shown is an advantageous improvement.

[0060] In a particularly advantageous configuration of the aforementioned type of machine, especially an inline or combined machine, the machine not only has machine parts (e.g., in the form of a roll-to-roll coating machine, especially a roll-to-roll coating printer, or roll-to-roll coating paintr) that apply fluid, particularly paint, to the substrate web once or preferably multiple times on its first side, and machine parts (e.g., in the form of a sheet-fed printing press) located downstream of the transverse cutting device 04 that print single sheets of substrate once or preferably multiple times on the second side, but also has two inking devices 02; 02' constructed in the substrate path downstream of an unwinder 01 preferably designed for easy replacement and upstream of the transverse cutting device 04, applying paint to the same web side, each inking device having at least one drying device 03; 03'; 03'' directly arranged downstream. These devices can be, for example, in Figure 5 As exemplarily shown, the inking mechanism is located on the side or upper side facing the device for inlet-side feeding, i.e., on the upward-pointing side of the substrate S in the inked area, or in an advantageous embodiment not specifically shown here, on the lower side, i.e., on the downward-pointing side of the substrate S in the inked area and / or on the side away from the device for inlet-side feeding. Here, the flexographic device preferably passes through the anilox roller 29 and the chamber doctor blade shape together with the fluid feed section in a closed manner, for example. In the advantageous case of an inline machine, one or more printing devices are connected downstream of the transverse cutting device 04. More than two such inking mechanisms may also be provided. Inking in offset printing methods generally achieves high printing speeds, and better surface coverage can also be achieved in the case of two or more such inking mechanisms, especially for inking devices 02, 02' including the anilox roller 29.

[0061] In a variant of this particularly advantageous configuration of the aforementioned machine, especially an inline machine, instead of two or more inking devices 02; 02 each operating according to the flexographic printing method and inking the same web side, each having at least one subsequent drying device 03; 03'; 03'', a single inking device operating according to the screen printing method can be provided in the substrate path of the substrate web. The screen printing method allows for the application of a fluid forming a barrier layer with a greater layer thickness in a single process.

[0062] In a particularly advantageous improvement, a first inking device that mates with a substrate web and, preferably, a device for accelerating drying and / or hardening, forms an assembly as a separate assembly or as a common finishing assembly.

Here, the separate or common assembly is configured as a module, such that the module is connected, on its upstream and downstream sides, via pre-prepared interfaces to pre-prepared interfaces of devices adjacent on the upstream or downstream side in the respective operating mode, without significant installation costs.

[0063] Selectively introducing or removing such individual or combined assemblies is also used in the aforementioned improvements, including more than one inking device 02; 02' and / or more than one device for accelerating drying and / or curing. Here, the assemblies can be selectively installed and removed, either individually or as a combination of having one inking device 02; 02' and one or more devices for accelerating drying and / or curing immediately following such inking devices 02; 02', or as a whole as an aesthetic assembly.

[0064] For this purpose, it is preferable that the last first web guide element 21 upstream of the transverse cutting device 04 and the last second web guide element 22 upstream of the sole or first inking device are respectively located at the same height, so that in the absence of inking devices 02; 02' and devices for accelerating drying and / or hardening, the web-shaped substrate S can be guided uninterruptedly towards the last second web guide element 22 upstream of the transverse cutting device 04 along with the last third web guide element 23 downstream of the unwinder 01, and in the presence of the aforementioned devices, it can be guided uninterruptedly towards the last second web guide element 22 upstream of the sole or last inking device observed upstream. Additionally or alternatively, for cases where there is a mechanical drive connection between at least one inking device and a drive composite including the transverse cutting device 04, a mechanical interface to the drive composite can be prepared, and for cases where the drive device is mechanically independent of the transverse cutting device 04, an interface to a wiring connection (e.g., a bus system) for guiding the electronic guide shaft can be prepared.

[0065] For the removal and introduction of common or corresponding assemblies, a movement path is preferably provided with a mechanism capable of enabling movement, such as a rolling element having a second track system 16 and located on the assembly, inking device 02; 02' and / or one or more devices for accelerating drying and / or hardening, as a corresponding, grouped assembly or common assembly, etc., capable of being moved laterally out of the machine guideline.

[0066] Alternatively, preferably, a movement path with a mechanism that allows movement can be provided, such as a first track system 14 and rolling elements disposed on the transverse cutting device 04 and / or preferably disposed on the unwinder 01. In the absence of an inking device or all inking devices 02; 02' and a drying device or all drying devices 03; 03'; 03'' or the dryer of the unwinder 01, the transverse cutting device 04 can be moved to a relatively close relative position via the rolling elements, especially the unwinder 01 can continue to move toward the transverse cutting device 04 via this relative position.

[0067] In handling and / or processing the web-shaped substrate S, the web-shaped substrate S is first unwound from the substrate roll 11 storing the substrate. The web-shaped substrate S is inked once or multiple times on a first side by at least one of the aforementioned inking devices 02, 02' using the aforementioned fluid. After the corresponding inking, the fluid-inked substrate S is dried and / or hardened at least on its surface by at least one device for accelerating drying and / or hardening. Furthermore, the fluid-inked substrate S, carrying at least the fluid dried and / or hardened on its surface, is cut into substrate segments S' by the transverse cutting device 04. The substrate segments S' are assembled into one or more stacks 13 downstream in the paper delivery device 06.

[0068] In an advantageous improvement, the substrate segments S' are printed and / or painted once or more on a second side opposite to the first side downstream of the transverse cut and before being assembled into a stack.

[0069] For the purpose of changing the operating mode, it is advantageous for the machine to be modified such that one or all of the inking devices 02; 02' and one or more drying devices 03; 03'; 03'' are removed from the machine alignment and from the substrate path on the side, and, for example, after removing the inking devices 02; 02' and the drying devices 03 or 03; 03'; 03'', the transverse cutting device 04 and the unwinder 01 are fed into a relatively close relative position.
