Description

[0001] The invention relates to a device for processing, in particular for punching, creasing, embossing and / or perforating, flat material, in particular paper, cardboard, corrugated board and / or plastic, according to the preamble of claim 1. Furthermore, the invention relates to a profile element according to the preamble of claim 19 and a method for processing flat material, in particular paper, cardboard, corrugated board and / or plastic, according to the preamble of claim 20.

[0002] Devices for processing, in particular for punching, creasing, embossing, and / or perforating, sheet materials are regularly referred to as die-cutting devices, die-cutting machines, or die-cutting automatics and are used especially in the printing and packaging industries for processing strip- or sheet-shaped materials made of paper, cardboard, corrugated board, and / or plastic. Such a die-cutting device typically has a processing plate called a die-cutting plate, from which several processing lines extend, forming a defined processing pattern. Furthermore, the die-cutting device usually includes a counter plate, called a counter-die plate, which is designed, for example, as an interchangeable die-cutting plate.

[0003] During a processing operation, the distance between the die-cutting plate and the counter-die-cutting plate is reduced by repositioning both plates or, preferably, by repositioning only one of the two plates, for example, the die-cutting plate. This means that the die-cutting device is open before the actual processing operation, and the die-cutting plate and the counter-die-cutting plate are spaced far enough apart to allow a material to be processed, such as a sheet of cardboard or corrugated board, to be inserted into the die-cutting device and thus between the die-cutting plate and the counter-die-cutting plate. During the subsequent die-cutting operation, which is explained below only by way of example using corrugated board as the material to be processed, the distance between the die-cutting plate and the counter-die-cutting plate is initially reduced until the processing line(s) rests on the corrugated board to be processed.The corrugated board is compressed in the contact area. Due to the increasing pressure, the processing line penetrates the corrugated board, with the processing line plunging further and further into the corrugated board as the die-cutting plate and counter-die-cutting plate are advanced.

[0004] The penetration depth of the processing line depends on the specific processing operation chosen. For example, the processing line can be a punching or cutting line that penetrates the corrugated board until it is completely punched or cut through and the cutting line rests on the counter-die. Alternatively, the processing line can be a scoring line, which either scores or embosses the material to be processed, for example, to weaken it and / or enable clean folding. Furthermore, the processing line can also be a perforation line, which creates small holes or cuts in the material to make it easier to tear and / or separate.Furthermore, the processing line can also be designed as a so-called combination line, which combines different processing operations, for example, die-cutting and creasing, thus forming a cutting-creasing combination line. In the context of the present invention, the term "processing lines" therefore encompasses all usable tools or lines with which all possible processing operations can be carried out, preferably in the printing and packaging industry, but not limited to this sector. Processing lines are typically manufactured from inelastic, inflexible, hard, and stable materials, such as steel or hard metal alloys, so that they can perform the desired operations during the processing process.

[0005] Accordingly, the terms "punching device," "punching plate," and "counter-punching plate," which are established technical terms in this field, do not imply any limitation to their use solely for the punching process. Naturally, as is customary in this field, they can be used for any machining operations that do not involve punching itself, but also include other processes such as creasing, embossing, and / or perforating, to name just a few of the most common methods.

[0006] Furthermore, profile elements, often also referred to as profile rubber elements, play an important role in a machining process and each form a flexible and elastic element that is placed along the machining lines to ensure an even pressure distribution during the respective machining process.

[0007] However, certain processing operations or working conditions, such as with very dry corrugated board or very thin linerboard, often pose a risk of the linerboard tearing due to the tensile forces acting on the material during processing. Furthermore, there is often a risk that, for example, during creasing, the fold will not be symmetrical, which can lead to so-called fishtailing, where the edges of the material curl or ripple outwards at the fold.

[0008] In contrast, the object of the present invention is to provide a device for processing, in particular for punching, creasing, embossing and / or perforating, flat materials, especially paper, cardboard, corrugated board and / or plastic, with which the risk of damage to the material, in particular tearing and / or fishtailing, can be reliably avoided. A further object of the invention is to provide a suitable profile element and a suitable method for this purpose.

[0009] This problem is solved by the features of the independent patent claims. Advantageous embodiments are the subject of the dependent claims relating thereto.

[0010] The invention relates to a device for processing, in particular for punching, creasing, embossing and / or perforating, flat material, especially paper, cardboard, corrugated board and / or plastic. The device has a processing plate from which at least one processing line projects, preferably several processing lines forming a defined processing pattern. At least one side flank of the at least one processing line, preferably both side flanks of the at least one processing line, is assigned at least one profile element which extends at least partially in the longitudinal direction along the assigned side flank and which is formed at least partially, preferably completely, from an elastomeric material.Such a profile element, which is elastic at least in certain areas, preferably essentially completely, therefore forms a profile rubber according to the prevailing technical term in the field.

[0011] According to the invention, the at least one profile element is suitable and designed to rest on and / or against a top surface of a material being processed during operation of the device and, in the compressed state, to generate a shear force in the direction of the processing line, which counteracts a tensile force generated by the processing line in the processing area.

[0012] This significantly reduces the resulting force on the material being processed, thus reliably preventing damage to the material. For example, especially when processing corrugated cardboard, this greatly reduces lateral movement of the flute(s) during the processing or creasing process, leading to better centering of the entire processing or creasing system.

[0013] According to a particularly preferred embodiment, the at least one profile element has a recess, preferably concave, on its inner profile side facing the processing line. This recess is formed by an inwardly curved section of the wall and / or, in the unloaded state, creates a clearance between the inner profile side and the processing line. This clearance is accessible in the unloaded state via a gap formed in the region of the free end of the processing line between the associated side flank of the processing line and the profile element. Such a geometry of the profile element is particularly advantageous in ensuring that the compressed profile element, when brought into contact with the material being processed, exerts a shear force on the material, for example, corrugated board, and in particular a cover layer and / or a flute section of corrugated board.a pressure is exerted in the direction of the machining line, which counteracts the tensile forces from the machining process. Furthermore, this specific geometry of the profile element allows counter-adjustments, such as finishing strips, to be easily, reliably, and precisely positioned on the free end of the machining line in the uncompressed state of the profile element, as will be explained in more detail below in connection with a particularly preferred embodiment.

[0014] According to a further particularly preferred embodiment, the curvature wall section, with respect to the profile element cross-section, extends between a first profile element wall section and a second profile element wall section of the inner profile side, which is spaced apart from it in the vertical axis direction of the profile element. In the unloaded state, the second profile element wall section is assigned to the free end of the machining line and has a defined gap distance to the associated side flank of the machining line to form the gap. The gap distance between the second profile element wall section and the side flank is, for example, 0.5 mm to 5.0 mm, preferably 1.0 mm to 4.0 mm, and most preferably 1.5 mm to 2.5 mm. With such a particularly preferred design, or...With such a particularly preferred gap spacing, not only can counter-adjustments, such as in particular finishing strips, be conveniently and reliably and precisely attached to the free end of the respective processing line, as described above, but in addition, a recess, preferably concave, is formed, which makes it possible in a particularly simple and reliable way for the profile element to pull the material to be processed, in particular corrugated board and here in particular a cover layer and / or a flute area of ​​corrugated board, in the direction of the processing line and thus counteract the tensile forces from the processing process.

[0015] To generate the desired shear force in the direction of the machining line in the compressed state of the profile element, it is particularly advantageous if the at least one profile element has an end wall section that forms a machining material contact area in the region of the free end of the machining line. Such a defined machining material contact area in the region of the free end of the machining line enables a flexible design of the profile element suitable for every application in the area particularly relevant for generating the shear force. In this context, it is also particularly advantageous if an inner profile side facing the machining line transitions into the end wall section forming the machining material contact area by means of a transition area formed in the region of the free end of the machining line.This also allows a defined transition area to be formed for the area of ​​the inner profile side, which is also relevant for thrust generation.

[0016] According to a particularly preferred embodiment, the second profile element wall section forms the transition zone between the curved wall section and the end wall section of the profile element extending away from the inner profile side and / or the machining line. With such a specific transition zone, designed according to the machining process, to an end wall section that forms the machining material contact area, the desired machining results can be easily achieved and controlled.

[0017] According to a further particularly preferred embodiment, this is additionally or alternatively achieved if the transition area is formed by a rounding, preferably by a rounded nose projecting from the inner profile side and / or towards the machining line, relative to the profile element cross-section. Such a rounding, especially a projecting rounded nose, advantageously avoids undesirable force peaks in the contact area, thus preventing damage to the material being machined. This is achieved particularly with a rounding, preferably a rounded nose, having a radius of 0.2 mm to 2 mm, more preferably 0.3 mm to 1.0 mm.

[0018] According to a further particularly preferred embodiment, the transition area is designed to merge smoothly, i.e., seamlessly without an edge or step, into the curved wall section and / or the end wall section. This ensures reliable compression of the profile element during operation without undesirable buckling due to any force peaks that may occur.

[0019] A particularly advantageous way of drawing the material to be processed or the material being processed towards the processing line is achieved with a particularly preferred embodiment in which the end wall section, relative to the profile element cross-section, forms an angled and / or inclined end-face contact surface of the profile element, which is inclined away from the top of a (particularly imaginary) material being processed towards the horizontal, i.e., for example, inclined backwards away from the inner profile side and downwards towards the processing plate, or sloping backwards from the transition area away from the inner profile side and towards the first profile element wall section. For this purpose, the end wall section can be inclined at an angle of 10° to 50°, preferably at an angle of 20° to 40°, to the horizontal, according to a particularly preferred specific embodiment.The horizontal is preferably formed by an imaginary horizontal and sloping end wall section.

[0020] According to a further particularly preferred embodiment, the end wall section transitions into an outer profile side via a second transition area on the side facing away from the inner profile side (relative to the profile element cross-section). Depending on the specific desired effect of the profile element, this second transition area may be rounded and / or the outer profile side may be straight or curved relative to the vertical axis of the profile element.

[0021] The second profile element wall section, preferably the rounded section, most preferably the rounded nose, can, according to a further preferred embodiment, project at least a portion of its length beyond the free end of the processing line in the unloaded state and relative to the profile element's vertical axis. This allows the second profile element wall section to come into contact with the material being processed before the free end of the processing line. This can be particularly advantageous, for example, in conjunction with corrugated cardboard, to ensure that the outer layer is drawn towards the processing line at an early stage. Alternatively, the second profile element wall section, preferably the rounded section, most preferably the rounded nose, can also be located below the free end of the processing line or at approximately the same height as the free end of the processing line.In such a setup, the free end of the processing line reaches the workpiece either after the second profile element wall section or simultaneously with it. This design allows the specific geometry of the profile element to be adapted precisely and flexibly to the respective processing task. This results in significant design freedom.

[0022] According to a further particularly preferred embodiment, the first profile element wall section with an adjoining area can directly abut an associated flank section of the side flank of the machining line, preferably abutting there without gaps. This allows for a particularly simple and reproducible arrangement of the profile element in the desired position. This is especially true if, according to a particularly preferred specific embodiment, the flank section is formed by a lower area of ​​the associated side flank of the machining line on the machining plate side.

[0023] The boundary area is preferably formed by a vertical surface of the first profile element wall section extending in the vertical direction of the profile element, wherein it is preferably provided that the surface, relative to the profile element cross-section, has a length of 0.5 mm to 3 mm, preferably 0.8 mm to 1.5 mm. As the inventor's experiments have shown, such a specific design of the first profile element wall section not only results in a reliable positioning and arrangement of the profile element on the processing plate or on the processing line, but also supports and does not impair the functionality of the profile element in the manner described above.

[0024] This also applies to another particularly preferred design, according to which the first profile element wall section projects beyond the second profile element wall section, with respect to the transverse direction and / or in the direction of the associated side flank of the machining line, for example by 0.5 mm to 5.0 mm, preferably by 1.0 mm to 4.0 mm, most preferably by 1.5 mm to 2.5 mm. Such a design also has the particular advantage that the desired gap spacing of the profile element in the area of ​​the free end of the machining line can be reliably and reliably formed and set in the desired manner.

[0025] In conjunction with the first profile element wall section, it is particularly advantageous for the first profile element wall section to transition smoothly, i.e., seamlessly without an edge or step, into the curved wall section. This ensures reliable compression of the profile element during operation without undesirable buckling due to any potential force peaks.

[0026] As the inventor's experiments have further shown, the desired results can be achieved in particular with a specific embodiment in which the total height of the profile element, based on the profile element cross-section and measured between the two outer surfaces of the second profile element wall section and the first profile element wall section facing away from each other in the vertical axis direction of the profile element, is 5.0 mm to 15.0 mm, preferably 6.0 mm to 12.0 mm, most preferably 7.0 mm to 10.0 mm.

[0027] According to a further particularly preferred embodiment, the first profile element wall section can transition on its underside, facing away from the curved wall section, into a bottom wall section of the profile element extending away from the inner profile side and / or the machining line. Such a bottom wall section is particularly advantageous for reliable attachment to a machining plate. Accordingly, it is preferably provided that the profile element is connected to the machining plate by means of the bottom wall section, preferably by means of a fastening element and / or an adhesive. An adhesive is preferred and is formed, for example, by an adhesive layer, such as one coated with an adhesive.

[0028] For a compact and small-scale design of the profile element, which is also easy to manufacture, it can be provided that the bottom wall section is a horizontal wall section, relative to the profile element cross-section, which transitions into an outer profile side of the profile element at its end facing away from the inner profile side.

[0029] The curved wall section can, in principle, be formed by any suitable curvature, but is preferably a C-shaped curved curvature, and particularly preferably a circular curved curvature with a defined radius of curvature. This ensures a uniform profile of the curved wall section, which helps to avoid undesirable buckling or flexing. According to a specific embodiment, it is particularly preferred that the radius of curvature is 3.0 mm to 15.0 mm, preferably 4.0 mm to 12.0 mm, and most preferably 4.0 mm to 10.0 mm.

[0030] Counter-treatments are generally known and refer to an auxiliary device used, for example, in the die-cutting or creasing of paper, cardboard, corrugated board, and / or plastic. Counter-treatments primarily include so-called finishing strips (also called channel finishing grooves), where one finishing strip is required per groove channel. The finishing strips themselves are constructed as described, for example, in DE 197 15 800 C2, namely with a carrier layer supporting one or two adjacent and spaced-apart, often beveled, material strips. This carrier layer is provided on its underside with an adhesive layer and a cover layer that protects the adhesive layer.The two spaced-apart material strips define a groove channel between them, in which a guide strip, designated as a mounting profile element, is detachably held. This guide strip, in a manner known per se, serves to be attached to a processing line in order to subsequently position the finishing strip precisely on an associated counter plate when the device is actuated accordingly. In conjunction with such finishing strips as counter plates, the inventive design of the profile elements, with their clearances accessible via the gap between the processing line and an inner profile side of a profile element, offers the possibility of a particularly advantageous, fast, and at the same time functionally reliable and positionally precise mounting of the finishing strips on the processing lines, which in turn has a beneficial effect on the precise positioning of the finishing strips on the counter plate.Accordingly, this particularly preferred embodiment provides for a counter plate associated with the processing plate and for a finishing strip as a counter-finish, which is suitable and designed to be adhered to the counter plate. The finishing strip has a carrier layer supporting two adjacent and spaced-apart material strips, wherein it is preferably provided on its underside with an adhesive layer and a cover layer covering the adhesive layer.

[0031] Furthermore, in this embodiment, it is provided that the two spaced-apart material strips form a groove channel between them in which a guide strip is detachably held, the guide strip being attachable to the free end of the processing line by means of a clamping device formed by two clamping legs, in order to detachably hold the finishing strip there, in particular for subsequent precise positioning of the finishing strip on the counter plate.Furthermore, at least one profile element is assigned to each of the two side flanks of the at least one machining line, which extends at least partially in the longitudinal direction along the assigned side flank, so that in the unloaded basic state a free space is formed between the inner profile side of the respective profile elements and the machining line, which in the unloaded basic state is accessible via a gap accessible from the side of the free end of the machining line between the assigned side flank of the machining line and the profile element.

[0032] Furthermore, in this embodiment, each of the two clamping legs, when the guide strip and thus the preparation strip are attached, extends through the respective gap between the processing line and the profile element and engages in one of the two free spaces, where it is clamped against the corresponding side flank of the processing line. Preferably, the respective profile element, more preferably the second wall section of the respective profile element, rests against the respective clamping leg when the preparation strip is attached.

[0033] The invention further claims a profile element for use in a device for processing, in particular for punching, creasing, embossing and / or perforating, flat processing material, especially paper, cardboard, corrugated board and / or plastic, preferably for use in a device as described above. The profile element according to the invention is suitable and designed to rest on and / or against a top surface of a processing material and, in its compressed state, to generate a shear force in the direction of the processing line, which counteracts a tensile force generated by the processing line in the processing area.

[0034] The advantages arising from this are identical to those already discussed in detail in connection with the device according to the invention. Therefore, to avoid repetition, reference is made to the previously stated explanations regarding the device.

[0035] This also applies to a particularly preferred embodiment of the profile element, according to which the profile element has, on its inner profile side facing a machining line in the mounted state, a recess, preferably concave, which is formed by an inwardly curved section of the curvature wall and / or which is suitable and designed to form a clearance between the inner profile side and an associated machining line in an unloaded basic state mounted on a machining plate, which is accessible in the unloaded basic state via a gap formed in the area of ​​the free end of the machining line between the associated side flank of the machining line and the profile element. This also applies to a particularly preferred embodiment of the profile element, according to which the section of the curvature wall, with respect to the profile element cross-section,between a first profile element wall section and a second profile element wall section spaced apart from it on the inner profile side, wherein the second profile element wall section is suitable and designed to be mounted on a processing plate next to a processing line such that the second profile element wall section is assigned to the free end of the processing line and, in the unloaded basic state, has a defined gap distance to the assigned side flank of the processing line.

[0036] The invention further claims a method for processing planar materials, preferably for processing strip- or sheet-shaped materials made of paper, cardboard, corrugated board and / or plastic, using a device as has already been discussed and described in detail. According to the invention, this method provides that, during operation of the device, the at least one profile element rests on and / or against a top surface of a material to be processed, preferably on a top layer of a corrugated board, and in its compressed state generates a shear force in the direction of the processing line, which counteracts a tensile force generated by the processing line in the processing area.

[0037] The resulting advantages have already been explained in detail in connection with the device, so reference is made to the previously made statements to avoid repetition.

[0038] They show: Fig. 1a a schematic and merely principled sectional view of an exemplary embodiment of a device according to the invention in the open state and with corrugated cardboard already inserted as an exemplary processing material, Fig. 1 legs of the Fig. 1a corresponding representation with closed device, Fig. 2a a schematic and enlarged detail view of a machining line arranged on a machining plate including profile elements arranged on both sides, Fig. 2b an enlarged individual view of a profile element from the Fig. 2a, Fig. 3a a schematic and exemplary representation of the device according to the invention in the open state and in conjunction with a finishing strip attached to the processing line, Fig. 3 legs of the Fig. 3a A corresponding representation of the device, in which the finishing strip is glued onto the counter plate by lowering the processing plate, Fig. 3c the device in the reopened state with the processing plate lifted.

[0039] In the Figure 1aA schematic and exemplary embodiment of a device 1 according to the invention for processing, in particular for punching, creasing, embossing and / or perforating, flat material, especially paper, cardboard, corrugated board and / or plastic, is shown. In the example shown, this device 1 has a flat processing plate 2, from which, by way of example only, a processing line 3 designed as a creasing line projects. It is understood that several processing lines forming a defined processing pattern can, of course, project from such a processing plate 2.

[0040] In the example shown here, each of the two side flanks 4 of the processing line 3 is assigned a profile element 5, which extends at least partially in the longitudinal direction (into the image plane) along the assigned side flanks 4 and which in the example shown here is made entirely of an elastomer material.

[0041] The device 1 further comprises a counter plate 6 associated with the processing plate 2, on which, in the example shown here, the Figure 1a A corrugated cardboard sheet already lies on the surface as a flat material to be processed. The device 1 is in the Figure 1a shown in the open state, in which the processing plate 2 together with the processing line 3 and the two profile elements 5 is arranged spaced apart above the corrugated cardboard 7 and thus the counter plate 6.

[0042] As can be seen in particular from the Figure 1bAs can be seen, during a processing operation the distance between the processing plate 2 and the counter plate 6 is reduced, here exemplified by moving the processing plate 2 towards the counter plate 6, thereby bringing both the processing line 3 and the profile elements 5 into contact with or resting on the corrugated board 7. This will be explained in more detail below. Before that, however, in connection with the Figures 2a and 2b An advantageous structure of the profile elements 5 will be explained in more detail: How this is derived from the two Figures 2a and 2bAs can be seen, the two profile elements 5 shown here as examples, which are designed as identical parts with regard to their geometric configuration, have a concave recess on the inner profile side 8 facing the machining line 3. This recess is formed by an inwardly curved section 9 of the wall. This section 9 of the wall is shown here as having a C-shaped, circularly curved bulge. The circularly curved bulge has a defined radius of curvature, which can be 3.0 mm to 15.0 mm, preferably 4.0 mm to 12.0 mm, and most preferably 4.0 mm to 10.0 mm. In the example shown here, the radius of curvature is designated R5, which corresponds to a radius of curvature of 5.0 mm.

[0043] As can be seen in particular from the Figure 2aAs can be seen, the concave recess formed by the curvature wall section 9 also forms a free space 10 between the inner profile side 8 and the machining line 3 in the unloaded basic state of the profile elements 5 shown here, which is accessible via a gap 12 formed in the area of ​​the free end 11 of the machining line 3 between the associated side flank 4 of the machining line 3 and the profile element 5.

[0044] As this can be seen from the Figures 2a and 2b As can be further seen, the curvature wall section 9, with respect to the profile element cross-section, extends between a first profile element wall section 13 and a second profile element wall section 14 spaced apart from it in the profile element vertical axis direction z. The second profile element wall section 14 is in the Figure 2aThe unloaded basic state shown is assigned to the free end 11 of the processing line 3 and has a defined gap distance to the respective assigned side flank 4 of the processing line 3 to form the gap 12. The gap distance between the second profile element wall section 14 and the respective side flank 4 is, for example, 0.5 mm to 5.0 mm, preferably 1.0 mm to 4.0 mm, most preferably 1.5 mm to 2.5 mm. In the example shown here, the gap distance in the Figure 2a 1.8 mm each.

[0045] As this can be seen from the Figures 2a and 2b Furthermore, as can be seen, the second profile element wall section 14 forms a transition area between the curved wall section 9 and an end wall section 15 of the profile element 5 extending away from the inner profile side 8 or the machining line 3. This end wall section 15 also forms, as will be shown below in conjunction with the Figure 1b It is explained in more detail that it is a processing material contact area.

[0046] As this will be further explained in the Figures 2a and 2b As can be seen, the transition area is specifically formed by a rounded nose 16 projecting from the inner profile side 8 and towards the machining line 3. The rounding of the nose 16 has, for example, a radius of 0.5 mm to 3.0 mm, preferably 1.0 mm to 2.5 mm.

[0047] As this can be seen from the Figures 2a and 2b As can be clearly seen, the transition area formed by the rounded nose 16 passes continuously, i.e. seamlessly without edge or step, into the curvature wall section 9 and into the end wall section 15.

[0048] The end wall section 15 forms here, in relation to the one in the Figures 2a and 2bThe profile element cross-section shown includes an angled or inclined end-face contact surface of the profile elements 5, which extends rearward from the transition area 16 away from the inner profile side 8 and slopes down towards the first profile element wall section 13 or towards the processing plate 2. The end-face wall section 15 is preferably inclined at an angle of 10° to 50°, and most preferably at an angle of 20° to 40°, to the horizontal, which is formed by an imaginary horizontal and uninclined end-face wall section (see dashed line). In the embodiment shown here, the Figures 2a and 2b This angle is only an example of approximately 25°.

[0049] From the Figures 2a and 2bIt is further evident that the end wall section 15, on its side facing away from the inner profile side 8 (with respect to the profile element cross-section shown here), transitions into an outer profile side 18 via a second transition area 17. This second transition area 17 is also rounded here as an example. Furthermore, the outer profile side 18 is shown here as having a straight line with respect to the profile element's vertical axis z.

[0050] As can be seen in particular from the Figure 2a As can be seen, in the embodiment shown here, the rounded nose 16 is located at approximately the same height as the free end 11 of the processing line 3 in the unloaded state. This means that the profile elements 5 come into contact with the processing material, here the corrugated cardboard 7, essentially simultaneously with the free end 11 of the processing line 3.

[0051] The Figures 2a and 2bIt can also be further deduced that the first profile element wall section 13 with an adjoining area directly and thus essentially without gaps abuts a lower area of ​​the side flanks 4 of the processing line 3, wherein this lower area of ​​the processing line 3 is opposite the free end 11 of the processing line 3 and is firmly anchored with a partial area in the processing plate 2.

[0052] The boundary area is formed here by a vertical surface 19 of the first profile element wall section 13, extending in the direction of the vertical axis. This surface can have a length of 0.5 mm to 3.0 mm, preferably 0.8 mm to 1.5 mm. In the example shown here, the surface 19 has a length of 1.0 mm.

[0053] As can be seen very clearly from the overview of the Figures 2a and 2bAs can be seen, the first profile element wall section 13 projects beyond the second profile element wall section 14, with respect to the transverse direction y and / or in the direction of the associated side flank 4 of the machining line 3. In conjunction with the direct contact of the surface 19 with the respective associated side flank 4 of the profile elements 5, this results in the first profile element wall section 13 projecting beyond the second profile element wall section 14 by the gap distance, in the example shown here by 1.8 mm.

[0054] As this can be seen from the Figures 2a and 2b Furthermore, it is also evident that the first profile element wall section 13 transitions smoothly, i.e. seamlessly without edge or step, into the curved wall section 9.

[0055] The total height of the profile elements 5, based on the profile element cross-section and measured between the two outer surfaces of the first profile element wall section 13 and the second profile element wall section 14 facing away from each other in the vertical axis direction z of the profile element, is, for example, 5.0 mm to 15.0 mm, preferably 6.0 mm to 12.0 mm, most preferably 7.0 mm to 10.0 mm.

[0056] The first profile element wall section 13 then transitions on its underside, facing away from the curved wall section 9, into a bottom wall section 20 of the profile elements 5 extending away from the inner profile side 8 or the machining line 3. The bottom wall section 20 is preferably a profile element with respect to the cross-section of the profile element shown. Figures 2a and 2b, horizontally extending wall section that transitions into the outer profile side 18 at its end furthest from the inner profile side 8. The bottom wall section 20 can also be provided with an adhesive, which is not shown here, so that the profile elements 5 can be reliably arranged and held in the desired position on the processing plate 2. The adhesive can, for example, be an adhesive layer.

[0057] The profile elements 5 are designed here as identical parts with respect to their geometric configuration, which generally corresponds to the preferred design and embodiment. Alternatively, however, if special machining tasks are required, different profile elements can be arranged on both sides of a machining line. These differences can relate to at least some of the geometric dimensions described above.

[0058] If the device 1 is now, as described in the Figure 1b In schematic and general terms, when closed, the two profile elements 5 with their end wall sections 15 come into contact with the corrugated board 7, as does the free end 11 of the processing line 3. The free end 11 of the processing line 3, which is for example made of a steel material, dips so deeply into the corrugated board 7 at the specific processing area 21, where the corrugated board 7 is to be scored, that the top layer 22, as well as the intermediate layer 23 and the two fluted layers 24, 25, are pressed towards a bottom layer 26. This exerts tensile forces, particularly on the top layer 22, which, for example, in the case of very dry corrugated board or a very thin top layer 22, can lead to tearing of the top layer. However, this is reliably prevented by the profile elements 5 designed according to the invention, since they are located in the Figure 1bIn the compressed state shown, a shear force 27 is generated in the direction of the processing line 3, which counteracts the tensile forces generated by the processing line 3 in the processing area 21. This reliably prevents the corrugated board 7 from tearing, especially in the area of ​​the top layer 22.

[0059] In the Figures 3a to 3c It is further demonstrated by way of example that a finishing strip 28 in conjunction with the profile elements 5 designed according to the invention can be attached to the counter plate 6 simply, reliably and with precise positioning: As can be seen from the Figures 3a to 3c As can be seen, the finishing strip 28 has a carrier layer 29 on which two adjacent and spaced-apart material strips 30 are arranged, forming a groove channel 31 between them in which a guide strip 32 is detachably held.

[0060] The guide strip is, as in the Figures 3a and 3bshown, by means of a clamping device formed by two clamping legs 33, can be attached to the free end 11 of the processing line 3 in order to hold the preparation strip 28 there, for subsequent precise positioning of the preparation strip 28 on the counter plate 6.

[0061] To attach the finishing strip 28, each of the two clamping legs 33 extends through the respective gap 12 between the processing line 3 and the respective profile element 5, so that each of the two clamping legs 33 engages in one of the two free spaces 10 and is held there under clamping contact against the corresponding side flank 4 of the processing line 3. It may be provided that the second profile element wall section 14 of the two profile elements 5, when the finishing strip 28 is attached, essentially rests against the respective clamping leg 33.

[0062] In the example shown here, the carrier layer 29 has an adhesive layer 34 on its underside, which can be, for example, an adhesive layer formed by an adhesive tape.

[0063] Based on the one in the Figure 3a With the preparation strip 28 in its attached position as shown, the device 1 can now be closed and, for example, the processing plate 2 can be lowered towards the counter plate 6 until the adhesive layer 34 comes into contact with the counter plate 6, causing the preparation strip 28 to adhere to the counter plate 6. This allows for precise positioning and alignment of the preparation strip 28 with respect to the processing line 3, which then ( Figure 3c ) can be lifted again from the preparation strip 28. It is understood that the adhesive force of the adhesive layer 34 must then be correspondingly greater than the clamping force of the clamping legs 33 on the processing line.

[0064] Subsequently, although this is no longer shown in the figures, the guide strip 32 can be removed from the groove channel 31 and the device 1 is ready for use. Even in conjunction with such a counter-machine, the following results are obtained in connection with the Figure 1b described processing advantages when using the profile elements according to the invention in conjunction with the device according to the invention.
