Description

[0001] The present application relates to a processing device for creasing a cardboard web according to the preamble of claim 1. Furthermore, the present application relates to a machine for processing a cardboard web according to the preamble of claim 16. Finally, the present application relates to a method for processing a cardboard web according to claim 17.

[0002] For the purposes of the present invention, the processing of the respective cardboard web relates to the production of boxes and cartons for packaging goods. The processing of a cardboard web into cartons involves various work steps or processes and various devices for mechanical processing by deformation without material removal. These devices are equipped, in particular, with various tools for creasing, cutting, perforating, and / or scoring the respective cardboard web. In the context of this application, "creasing" a cardboard web is understood to mean a pressing process on the respective cardboard material, in which the cardboard web is pressed in its thickness direction but otherwise remains undamaged. In contrast, "scoring" involves at least cutting into the cardboard web.For example, at least one layer of a multi-layered cardboard web is cut through, while at least one other layer remains intact. "Cutting" involves completely cutting through the cardboard web, separating two adjacent sections. "Perforating" refers to a section-by-section process in which spaced-apart slits or cuts are made in the cardboard web to weaken it in a controlled manner.

[0003] The cardboard web can be made of corrugated board or single- or multi-ply solid board. High-quality cardboard material, for example, consists of three layers, with the outer layers optimized for strength and an inner layer between them optimized for volume. Corrugated cardboard boxes are commonly used for packaging goods.

[0004] For the purposes of this application, a "cardboard web" is understood to mean, for example, an "endless" cardboard web whose length is significantly greater than its width. For instance, a cardboard web may have a length of 50 m and a width of 2 m or less. Such endless cardboard webs are typically stored in a leporello fold, for example, in a magazine of a machine that processes the cardboard web. Likewise, for the purposes of this application, a cardboard web can also be understood—unless otherwise specified—to mean a finite section of cardboard intended for processing into a carton. Before processing, the cardboard web is typically unfolded.

[0005] To manufacture products from cardboard, especially corrugated or solid board, grooves, slits, and / or perforations are typically introduced into the respective cardboard web. Slitting involves cutting narrow indentations into the cardboard web, for example, cutting through at least one top layer of a multi-layered cardboard material. Scoring, on the other hand, describes a local compression of the cardboard web in the thickness direction. This is done along straight lines, resulting in so-called "creases." The cardboard web is later bent or folded along these crease lines to produce, for example, a box from the flat sheet of cardboard.

[0006] To create a cardboard web with a suitable contour for carton production, the cardboard web can be cut. Specifically, a continuous cardboard web can be separated into individual sections by means of a processing device that cuts the web in a direction perpendicular to the feed direction, thus separating a single section from the cardboard web. This section can then be further processed into a carton.

[0007] In conventional machines for processing cardboard webs, the web is taken from a magazine within the machine and fed to a first processing station by means of a feeding device, where at least one initial processing step is carried out. Typically, such machines comprise several processing stations arranged in a row in the feed direction, so that the cardboard web passes through the individual processing stations sequentially. Each processing station is responsible for one or more of the processing steps mentioned above, and the processing stations can, for example, be divided according to a processing direction. Thus, one processing station can be responsible for transverse processing (perpendicular to the feed direction of the cardboard web), and another processing station for longitudinal processing (parallel to the feed direction of the cardboard web). State of the art

[0008] A processing device of this type is described, for example, in German patent DE 10 2015 011 399 B4. There, the processing device is designed and configured to score and cut a cardboard web. For this purpose, the processing station carries both a scoring tool and a cutting tool. Because the tools are movable relative to each other, they can be selectively engaged with the cardboard web. In this way, it is possible to score the cardboard web either with the scoring tool or with the cutting tool, to cut, perforate, or score it. The known processing device does not use a rotatable element for the scoring step, but rather a stationary element, namely a sliding skid with a profile arranged or formed on it.The creasing process involves a linear displacement of the material through applied pressure to create the crease line and thus the flexibility of the cardboard.

[0009] For processing cardboard, it is a disadvantage that, despite the presence of scored lines, the cardboard material tends to spring back after being folded along the respective score line. A fold or crease applied along a score line, for example, at a 90° angle, therefore generally does not remain intact without support or locking. Instead, in the absence of external influences, it at least partially reverts to its original shape due to the material properties of the cardboard. Consequently, when the cardboard is conveyed along a processing line, it can happen that a fold in the cardboard web is no longer present in the desired manner or extent by the time it arrives at a processing station following a folding station.For example, a 90° fold in a cardboard section relative to an adjacent section may have already "returned" to a 70° angle by the time it arrives at the next processing station. This can hinder further processing of the cardboard. Therefore, it would be desirable if the cardboard material did not have these springback properties, so that any applied folds could be better retained for the purpose of further processing of the respective cardboard. Task

[0010] The present application is therefore based on the task of providing a processing device by means of which mechanical creasing is possible and which solves the problem of the tendency of the cardboard material to spring back. Solution

[0011] The underlying problem is solved according to the invention by means of a processing device with the features of claim 1. Advantageous embodiments will become apparent from the associated dependent claims, the description and the exemplary embodiment.

[0012] The processing equipment is designed and set up to score a sheet of cardboard. The cardboard will later be folded along this scored line.

[0013] The machining device comprises a support frame and a grooving tool arranged on the support frame. The support frame can, for example, and preferably, be made of metal. Preferably, the support frame is formed in one piece. The support frame can, for example, and preferably, be designed in the form of a frame to which further functional elements of the machining device can be easily attached or mounted. The support frame preferably defines a plurality of receiving chambers in which the functional elements of the machining device are received. Preferably, the height of the support frame, measured parallel to a vertical axis of the machining device, significantly exceeds the width of the support frame measured transversely to the vertical axis and transversely to a longitudinal direction of the machining device (parallel to a transverse axis of the machining device).

[0014] The creasing tool comprises a creasing element. This creasing tool is designed and configured so that, during normal operation of the processing unit, the creasing element can come into contact with the cardboard web. This enables the creasing tool to create a crease line in the cardboard web, along which the cardboard web can then be folded. The creasing element is preferably designed such that its shape defines a processing direction in which the crease line can be created in the respective cardboard web by means of the creasing element when the processing unit is moved relative to the respective cardboard web during normal operation. The locations and lengths over which a crease line is to be created in the respective cardboard web are determined by the design of the cardboard to be produced.The creasing element can, for example, and preferably, be formed by a sliding skid as described separately below. In such a configuration, the machining direction is oriented parallel to the longitudinal direction of the sliding skid. An embodiment in the form of a round creasing wheel is also conceivable, which is rotatably mounted about a pivot axis oriented parallel to the transverse axis of the machining device. In this configuration, the machining direction is oriented perpendicular to the pivot axis of the creasing wheel. Other configurations are also conceivable. The essential characteristic is its ability to make contact with the cardboard web, thereby displacing the cardboard material and creating the creasing line.

[0015] In a configuration where the processing unit is integrated into a higher-level machine, the creasing tool can, for example, be part of a processing station within the machine, which processes the cardboard web. This processing can involve longitudinal processing (parallel to the feed direction of the cardboard web) and / or transverse processing (perpendicular to the feed direction of the cardboard web). Downstream of this processing station, another processing station, such as a folding station, can be arranged, which folds the cardboard web and thus produces the final product. In the folding station, sections of the cardboard web are angled or folded relative to each other, with one or more previously applied creasing lines serving to prepare the fold accordingly. Therefore, in such a configuration, the cardboard is folded along previously applied creasing lines.There, the cardboard web or the cardboard material of the cardboard web is weakened or embossed as a result of the pressing contact with the creasing element, so that the cardboard material gives way along the creasing lines under the application of a force and thereby creates the defined fold.

[0016] For the interaction of the processing unit with a given cardboard web, at least a partial linear relative movement between the two is required. It is fundamentally irrelevant whether the cardboard web is stationary and the processing unit is actively moved in a relatively linear direction relative to the cardboard web, or vice versa, whether the processing unit is stationary and the cardboard web is actively moved in a linear direction. It is also conceivable that both the cardboard web and the processing unit are actively moved simultaneously, with these movements differing in such a way that the processing unit and the cardboard web move relative to each other.Particularly in transverse processing, where a creasing line is introduced into the cardboard web transversely in the direction of its feed, the cardboard web is generally stationary while the processing unit, as part of a processing station, moves transversely to the cardboard web and, in the process, introduces the creasing line into the cardboard web by means of the pressing contact of the creasing element of the creasing tool. The processing unit can, for example, and preferably, be arranged on a crossbeam of the processing station extending transversely across the cardboard web and be movable along the crossbeam by means of a drive mechanism.

[0017] According to the invention, the processing device further comprises an dispensing unit arranged on the support frame. The dispensing unit is designed and configured to dispense a liquid onto the cardboard web. The dispensing unit is arranged and aligned on the support frame such that, during normal operation of the processing device, the liquid can either be dispensed onto an area of ​​the cardboard web where the creasing line is subsequently created by the creasing element, or onto the creasing line already created by the creasing element.In other words, it is equally possible to apply the liquid either "in front" of the creasing element, in which case the cardboard web is then creased in the area where the liquid has already been applied, or to apply the liquid "behind" the creasing element, so that the liquid is applied to the already created crease line. The result after processing is a cardboard web with a crease line along which the web is coated with liquid. The application of the liquid can be calculated, in particular, based on the design of the cardboard to be produced.

[0018] In the simplest case, this liquid could be water. However, other liquids are also conceivable, especially those with rapidly volatile properties. Thus, the liquid could, for example, and preferably, contain at least some alcohol.

[0019] Preferably, the dispensing unit is arranged in series in front of or behind the grooving tool, viewed in the longitudinal direction of the machining device. If the grooving element defines a machining direction as described above, this machining direction is preferably oriented parallel to the longitudinal direction of the machining device.

[0020] When the dispensing unit is arranged in series in front of the creasing tool, the liquid is applied to the still "uncreased" cardboard web by the dispensing unit during normal operation of the processing equipment, before the creasing line is subsequently created by the creasing element. Due to the arrangement of the dispensing unit "in series in front of the creasing tool," the creasing line is created along the line along which the liquid was immediately applied to the cardboard web.

[0021] Conversely, the liquid is only dispensed after the crease line has been created if the dispensing unit is positioned in line behind the creasing tool. In this case, the crease line is created first, and then the liquid is applied to the cardboard web along the already formed crease line by means of the dispensing unit. Due to the arrangement of the dispensing unit "in line behind the creasing tool," the liquid is applied to the cardboard web precisely along the line along which the crease line was created immediately beforehand. This design and procedure is generally preferable, as it can be assumed that the still "dry" cardboard web can be processed more effectively by the creasing element without undesirably damaging the cardboard material.However, the option of applying the liquid before creating the groove line, as explained above, is also conceivable in principle.

[0022] The dispensing unit can, for example, and preferably, comprise an application nozzle through which the liquid is dispensed in the form of a spray cone extending conically around a main spray direction. Dispensing the liquid in the form of a spray cone results in a linear application of the liquid on the cardboard web, which occurs during the dispensing of the liquid while the processing device moves relative to the cardboard web. This linear application has a certain width measured transversely to a longitudinal direction of the linear application. Preferably, the dispensing unit is designed such that the spray cone is matched to the creasing tool or creasing element, so that the width of the creasing line, viewed transversely to a longitudinal direction of the creasing line, corresponds at least substantially to the width of the linear application of the liquid on the cardboard web.This ensures that, after processing with the processing device, the groove line is at least substantially completely covered with the applied liquid. In other words, the groove line and the liquid application line are preferably "congruent," both in their length and their width.

[0023] The processing device according to the invention has many advantages. In particular, it enables the processing of a cardboard web to introduce a creasing line both by mechanical processing using the creasing tool and, additionally, by the application of liquid. In this way, the processing device can produce a result in a single operation where, after processing, the cardboard web is provided with a crease line wetted or treated with liquid. Subsequent folding of the cardboard web along this crease line is not subject to a return to its original shape, as is the case in the prior art, where the cardboard material tends to counteract the crease and deform back. Instead, the crease applied along the crease line remains stable, so that the folded cardboard web can be particularly well fed into further processing.

[0024] If the processing unit is moved relative to a stationary cardboard web during the application of a crease line, it can be advantageous for the dispensing unit to be connected to a liquid pump via a flexible line, for example, and preferably, a flexible hose. The liquid is pressurized from a reservoir and thus supplied to the dispensing unit. By means of appropriate control of the dispensing unit, a valve in the dispensing unit can be switched as needed, for example, and preferably, so that the dispensing of the liquid is coordinated with the creation of each crease line. The valve is, for example, and preferably, designed as a solenoid valve and is an integral part of the dispensing unit.

[0025] In an advantageous embodiment of the processing device, the creasing element is formed by a sliding skid extending parallel to the longitudinal direction of the processing device. The sliding skid is provided with a profile on its underside, which faces the cardboard web during normal operation of the processing device. This profile can, for example, and preferably, be formed by a creasing edge or a creasing surface. When configured as a creasing edge, this profile can, for example, and preferably, be convexly curved and extend longitudinally along the underside of the sliding skid.If the creasing element is formed by such a sliding skid, the sliding skid is brought into contact with the upper surface of the respective cardboard web to create a creasing line. The profile on the underside of the sliding skid makes contact with the cardboard web, thereby pressing it inwards along its thickness. With relative movement between the processing device and the cardboard web, the cardboard web is thus pressed inwards along a line that then forms the creasing line. The creasing element, designed as a sliding skid, defines a processing direction by its elongated length, which is suitable for creating the respective creasing line in the cardboard web. This processing direction is oriented parallel to the longitudinal direction of the processing device.

[0026] If the creasing element is formed by a sliding skid as described, it can be further advantageous if the dispensing unit is arranged, viewed in the longitudinal direction parallel to the sliding skid, at least substantially aligned with the profile. This design has the advantage that the dispensing of the liquid can be carried out particularly easily in conjunction with the creation of the creasing line. In other words, this design ensures that the liquid can be dispensed relative to the creasing line in such a way that, after processing of the respective cardboard web, the web has a creasing line impregnated with liquid. As described above, it is conceivable that the liquid is applied to the cardboard web either before or after the creasing line is created.

[0027] In an advantageous embodiment of the processing device, the dispensing unit is arranged on the support frame such that an end-facing application nozzle of the dispensing unit, through which the liquid can exit during normal operation, is located, relative to the vertical axis of the processing device, at least substantially at the same height as the creasing element. This design is intended to ensure that the dispensing unit is positioned as close as possible to the cardboard web to be processed, such that the end-facing application nozzle, through which the liquid is effectively dispensed, is located in the immediate vicinity above the cardboard web during normal operation. In this way, the liquid can be applied to the cardboard web with particular precision during normal operation.The height level at which the creasing element is located is also in the immediate vicinity above the cardboard web when the processing device is operated as intended.

[0028] In an advantageous embodiment of the processing device, the support frame has a receiving chamber enclosed on at least two sides, in which the dispensing unit is arranged or received. Preferably, the receiving chamber has a front wall and a rear wall, viewed in the longitudinal direction of the processing device. The dispensing unit is received between the front and rear walls within the receiving chamber. For example, and preferably, the dispensing unit can be screwed to one of the two walls and thus fixed within the receiving chamber.

[0029] In an advantageous embodiment of the processing device, the dispensing unit is arranged on the support frame such that a main spray direction of the dispensing unit, into which the liquid is primarily dispensed from an end nozzle of the dispensing unit during normal operation, is inclined at a spray angle towards the creasing element relative to a transverse plane of the processing device. The transverse plane is defined as being parallel to the vertical axis of the processing device and orthogonal to its longitudinal direction. The described arrangement of the dispensing unit has the advantage that the liquid can be applied to the cardboard web particularly close to the creasing element or the creasing line that has already been created or is yet to be created.Thus, the oblique inclination of the main spray direction ensures that the dispensed liquid, originating from a distal tip of the application nozzle, exhibits a horizontal movement component oriented parallel to a plane of the respective cardboard web, along the longitudinal direction of the processing unit. In this way, the liquid can be brought closer to the creasing element of the creasing tool in a horizontal direction from the application nozzle before it reaches the surface of the cardboard web. Due to space constraints within the processing unit, the dispensing unit cannot typically be positioned arbitrarily close to the creasing element on the support frame.The inclined angle of the main beam direction can at least partially overcome a space-related distance between the creasing element and the dispensing unit, ensuring that the introduction of the creasing line into the respective cardboard web and the application of the liquid take place immediately one after the other when the processing device is operated as intended.

[0030] In a preferred embodiment, the beam angle is between 1° and 40°, preferably between 10° and 40°, and more preferably between 20° and 30°.

[0031] In an advantageous embodiment of the processing device, the device includes a creasing adjustment element that interacts with the creasing tool. The creasing adjustment element is designed and configured to move at least parts of the creasing tool relative to the support frame. This movement preferably occurs, at least partially, in a direction parallel to the vertical axis of the processing device. The creasing adjustment element thus allows the creasing tool to be moved between an active and an inactive position. When in the active position, at least the creasing element is lowered in a direction parallel to the vertical axis of the processing device such that it engages the cardboard web in a pressing manner, thereby creating the crease line. In contrast, no such engagement occurs when the creasing tool is in its inactive position.Thus, the creasing adjustment element allows for the on-demand creation of creasing lines in the respective cardboard web without requiring the entire processing unit to be moved parallel to the vertical axis. This allows creasing lines to be introduced into the cardboard web, preferably in sections, specifically only along those sections where the cardboard web will later be folded. The creasing adjustment element can, preferably, be pneumatically, hydropneumatically, hydraulically, or electrically driven. The creasing adjustment element can, preferably, be connected to or interact with the creasing tool via a lever mechanism.

[0032] If the processing unit includes such a creasing adjustment element, it can be particularly advantageous if, during normal operation of the processing unit, the movement of the creasing tool into its active position is synchronized with the dispensing of the liquid by the dispensing unit. Thus, it can be advantageous if the liquid is dispensed only when a creasing line is being created in the cardboard web. In other words, the application of liquid to the cardboard web only occurs along those sections where a creasing line has either already been created or is currently being created. With this operating mode, the dispensed liquid and the created creasing line are therefore identical or overlapping on or in the cardboard web after processing by the processing unit.The application of the liquid and the introduction of creasing lines into the respective cardboard web are calculated based on the design of the cardboard to be produced. This enables precise and targeted treatment of the cardboard web to ensure the desired properties of the final product.

[0033] If the processing device includes the described creasing adjustment element, it can be further advantageous if the creasing element is pivotally connected to the support frame. In this configuration, the creasing element can be pivoted relative to the support frame about a pivot axis oriented parallel to a transverse axis of the processing device by means of the creasing adjustment element. Such a pivoting movement is particularly well suited to lowering the creasing element as needed, i.e., bringing it into engagement with the respective cardboard web (activation position of the creasing tool), or conversely, raising the creasing element, i.e., releasing a previously existing engagement with the respective cardboard web (inactivity position of the creasing tool). The pivotal arrangement of the creasing element on the support element is particularly advantageous if the creasing element is formed by the sliding skid described above.

[0034] In an advantageous embodiment of the processing device, it features a cutting tool arranged on the support frame. The cutting tool comprises a cutting element, preferably in the form of a circular blade. The cutting tool is designed and configured so that, during normal operation of the processing device, the cutting element can come into contact with the cardboard web and process the web along a working line. For example, and preferably, the cardboard web can be cut, scored, or perforated along the working line by means of the cutting element. This can depend on both the design of the cutting element and the operating mode of the cutting tool. For example, the cutting element can be a circular blade with a continuous or serrated cutting edge.A continuous cutting edge is particularly well-suited for cutting a single sheet of cardboard, while a serrated cutting edge is better suited for perforating the cardboard. A cutting tool comprising multiple cutting elements is also conceivable. In this case, it is advantageous if the cutting elements are designed differently, thus enabling the broadest possible range of functions for processing cardboard sheets.

[0035] If the processing device includes a cutting tool, it is further advantageous if the processing device also includes a cutting adjustment element that interacts with the cutting tool. The interaction of the cutting adjustment element with the cutting tool is such that at least parts of the cutting tool can be moved relative to the support frame by means of the cutting adjustment element. The movement is preferably achievable at least partially in a direction parallel to the vertical axis of the processing device. Analogous to the creasing adjustment element described above, the cutting adjustment element offers the advantage that the cutting element can be brought into contact with the cardboard web as required. Thus, the cutting tool can be alternately switched between an active and an inactive position by means of the cutting adjustment element.When in the active position, at least the cutting element is lowered in a direction parallel to the vertical axis of the processing device such that, during normal operation of the processing device, it comes into contact with the cardboard web and cuts, scores, or perforates it. When the cutting tool is in the inactive position, however, the cutting element is raised in a direction parallel to the vertical axis to such an extent that, during normal operation of the processing device, it does not come into contact with the cardboard web, and therefore no processing takes place. The cutting adjustment element can, for example, and preferably, have a pneumatic, hydropneumatic, hydraulic, or electric drive. The cutting adjustment element can, for example, and preferably, be connected to or interact with the cutting tool via a lever mechanism.

[0036] The arrangement of both a cutting tool and a creasing tool on the processing unit expands the unit's functionality. With this configuration, it is possible to either crease a cardboard web using the creasing tool and simultaneously apply the liquid to the web using the application unit, or to process the cardboard web using the cutting tool, specifically cutting, scoring, or perforating. Applying the liquid to the cardboard web is also possible when using the cutting tool.

[0037] In a preferred embodiment of the machining device, the cutting tool has a bearing arm on which the cutting element is arranged, wherein the bearing arm is pivotally connected to the support frame and can be pivoted relative to the support frame by means of the cutting adjustment element about a pivot axis oriented parallel to a transverse axis of the machining device.

[0038] Provided the processing device includes the described cutting tool and the creasing element of the creasing tool is formed by the sliding skid described above, it can be particularly advantageous if the sliding skid has an elongated slot extending from its top to its bottom. This slot extends longitudinally along the processing device and thus along the sliding skid. In this configuration, the creasing tool is arranged relative to the cutting tool, and the slot is dimensioned to match the cutting element, such that the cutting element can pass through the slot from the top of the sliding skid to the bottom. In this way, the cutting element can engage with the cardboard web as required, allowing the cardboard web to be processed by the cutting element.This design is particularly advantageous with regard to its especially compact construction, since the cutting tool and the grooving tool can be arranged not next to each other, but more or less one above the other.

[0039] To move the cutting tool into its active position, the cutting element is lowered through the slot in the sliding skid by means of the cutting adjustment element, thus moving the cutting tool into its active position. It is theoretically possible for the creasing tool to remain in its active position, meaning that the profile of the sliding skid comes into contact with the cardboard web at the same time as the cutting element engages. However, typically the creasing tool is moved into its inactive position by means of the creasing adjustment element when the cutting element is to engage with the cardboard web. In other words, the cutting tool and the creasing tool preferably alternate between their respective active and inactive positions.After all this, it is particularly advantageous if the machining device comprises the cutting tool, the cutting adjustment element, and the grooving adjustment element in combination, with the grooving element being formed by the described sliding skid. The machining device designed in this way is particularly space-saving and has an advantageous range of functions.

[0040] In a preferred embodiment of the machining unit, it is designed as an assembly intended to be mounted as a whole on a higher-level machine. Preferably, in this embodiment, the machining unit comprises at least one connecting section by means of which it can be mounted on the higher-level machine, for example, on a crossbeam of a machining station of the machine. The connecting section can, for example, and preferably, include a linear guide by means of which the entire machining unit can be moved linearly along the higher-level crossbeam. The connecting section is preferably located on the upper side of the support frame facing away from the grooving tool. The assembly design allows for a particularly compact construction and easy replacement of individual machining units in the event of maintenance or repair.

[0041] The underlying problem is further solved by means of a machine with the features of claim 16. Advantageous embodiments will become apparent from the description and the exemplary embodiment.

[0042] The machine is set up to process a sheet of cardboard, folding the cardboard sheet into a box. The folding of the cardboard sheet can preferably also be carried out using the machine.

[0043] The machine comprises at least one magazine for holding a cardboard web folded in a leporello fold. Furthermore, the machine comprises a feeding device for feeding the cardboard web from the magazine to at least one processing station of the machine. Accordingly, the machine comprises at least one processing station, preferably a plurality of processing stations.

[0044] The feed of the cardboard web is effected, for example, and preferably, by the processing stations, which, for example, have drive means in a manner known per se, such as, for example, and preferably, actively driven drive rollers that are in contact with the cardboard web and are therefore suitable for driving it in the feed direction. The cardboard web can, in principle, be fed continuously or intermittently. If transverse processing is carried out, the feed is generally intermittent, so that the cardboard web is stationary while the transverse tool processes the cardboard web in a direction perpendicular to the feed direction. In longitudinal processing using the longitudinal tool, the cardboard web does not need to be stationary.

[0045] If multiple processing stations are provided, they are arranged in a series along a processing path of the machine in the feed direction. This arrangement of the processing stations ensures that the cardboard web, as it feeds along the processing path, reaches each individual processing station sequentially and can be processed by each one.

[0046] The at least one processing station has at least one longitudinal tool by means of which the cardboard web can be processed along at least one processing line oriented parallel to the feed direction. The processing can consist of creasing, cutting, scoring, and / or perforating the cardboard web along the processing line. Furthermore, either the same processing station or a different processing station has at least one transverse tool by means of which the cardboard web can be processed along at least one processing line oriented transverse to the feed direction. The processing with the transverse tool can also consist of creasing, cutting, scoring, and / or perforating the cardboard web along the processing line. The processing station comprising the at least one transverse tool can be the same processing station that also comprises the at least one longitudinal tool.It is also conceivable that these are different machining stations. It is also conceivable that different machining stations each include a longitudinal tool and / or a transverse tool.

[0047] Furthermore, for example, and preferably at least one processing station of the machine can be a folding station where the cardboard web can be folded. Preferably, the machine comprises a plurality of such folding stations to enable multiple folding operations to be performed successively. If at least one such folding station is present, it is preferably arranged downstream in the feed direction of at least one preceding processing station, by means of which the cardboard web can be creased, scored, cut, and / or perforated. Preferably, all processing stations where the cardboard web can be creased, scored, cut, and / or perforated are arranged upstream of a first and, if applicable, further folding stations.

This ensures that the liquid is directed from the distal end of the application nozzle. 35 viewed in the horizontal direction (that is, in the direction parallel to the longitudinal direction) 12 the processing facility 1 ) towards the groove element 6 to be applied. This creates a horizontal distance between the application unit. 11 and the groove element 6 at least partially overcome, so that the liquid is in the immediate vicinity of a rear end of the groove element 6 onto the cardboard web 2 can be applied.

[0063] The application unit 11 is attached to the support frame in this way 3arranged and aligned so that during normal operation of the processing equipment 1 the liquid onto the cardboard web 2 is applicable. This can be done either by applying the liquid to the area still covered by the groove element. 6 Grooving line to be produced 9 is applied or onto which the groove element has already been applied. 6 generated groove line 9. In the first variant, the application of the liquid to "the groove line yet to be created" is meant. 9" an application of the liquid to an area of ​​the cardboard web 2, in which the grooving element is subsequently used 6 the groove line 9 into the cardboard web 2 is introduced.

Thus, the bearing arm 20 around a parallel to the transverse axis 37 the processing facility 1 oriented swivel axis 22 relative to the support frame 3 Swivelable. The swivel axis 22 of the bearing arm 20 In the example shown, it is congruent with the pivot axis. 19 of the groove element 6. On the bearing arm 20 is the cutting element 21 mounted so that by means of a pivoting of the bearing arm 20 around the pivot axis 22 the cutting element 21 on a circular path around the pivot axis 22 is movable. This is due to the bearing arm's at least essentially horizontal orientation. 20 This movement is analogous to the groove element. 6 at least essentially in a movement in a vertical or parallel direction to the vertical axis15 oriented downward direction. In this way, the cutting tool can 5 It can be alternately switched between an active and an inactive position. In the former, the cutting element is located 21 in contact with the cardboard web 2 and can accordingly along a work line 10 Processing. Depending on the degree of lowering of the cutting element. 21 can the cardboard track 2 when the cutting tool is available 5 in its active position, scratched or cut.

[0072] In a particularly advantageous way, this acts as a sliding skid. 6' trained groove element 6 in the example shown, one parallel to the longitudinal direction 12 the elongated slot extending from the processing device 24 up. This penetrates the skid plate. 6' from their upper side 23 to its underside 7.This design has the advantage that the cutting element 21 immediately above the groove element 6 can be arranged. To the cutting element 21 in contact with the cardboard web 2 To bring it about, the same can be achieved through the action of the cutting adjustment element. 18 through the slot 24 They can be lowered through this. This design allows for a particularly space-saving implementation of the processing equipment. 1 in the direction of the transverse axis 37 (Latitude).
