Definitions
- the invention relates to methods for supporting the establishment of a punching device with a changeable hole pattern, according to the preamble of claim 1, and to an apparatus for carrying out the method according to claim 12.
- punching devices are found in many different areas of industry, depending on the material being processed.
- Devices for processing sheet metal or textiles, or cardboard and paper are often equipped with interchangeable punching tools in order to introduce different hole patterns into different materials.
- punching tools that can produce changeable hole patterns without being replaced.
- One possibility here is to bring stamps which are mounted in the punching tool into an active end position, in which they create a hole in the material when actuated, or into a passive end position, in which the stamps do not when the device is actuated contribute to a hole.
- These punching tools can be rotary or linear tools, i.e.
- stamps that are attached to a shaft and create a hole pattern in interaction with a die roller, or stamps that create a hole pattern in a material by a linear displacement, such as how with a hand punch for paper.
- the hole pattern consists of holes that lie on a line, others around holes that are distributed over a plane, similar to a matrix.
- Some of these punching devices process only one piece of material per processing operation, others process a stack of materials, especially when the materials are very thin, such as paper or foil.
- Some of these punching devices are automatically set up in that a control, by means of suitable adjusting means, brings at least some of the punches into one of the end positions.
- a control by means of suitable adjusting means, brings at least some of the punches into one of the end positions.
- Such a device is known, for example, from German patent application DE 102 48 688.
- flying processing means that the sheet-like substrates are processed in the moving state, in contrast to systems in which several sheet-like substrates in the stationary state, e.g. to be punched or trimmed.
- the sheet-like substrates are individually processed and then collected, whereas in other processes, the sheet-like substrates are first collected and subsequently processed.
- the flying processing of sheet-like substrates has the advantage that this processing corresponds better to the workflow of a Dracl machine for sheet-like substrates, which typically prints the sheet-like substrates sequentially. That is why it is flying
- the hole patterns that are introduced into sheet-shaped printing materials essentially differ in the position and the number of holes that are punched. For example, a distinction is made between the European 2 or 4 hole pattern or that
- US Pat. No. 2,116,391 discloses a device for flexibly setting punching patterns in a punching device.
- individual punches are fixed on axially movable sprockets.
- the sprockets which are also equipped with a scale, ensure that the punches are positioned precisely on the circumference of the sprockets, the same applies to the positioning of the associated dies.
- the stamps are screwed individually in their intended position. This allows a flexible change, but takes a lot of time.
- US Pat. No. 5,669,277 proposes a rotary punch device in which holders for punches are provided in a first shaft for a large number of different hole combinations.
- the change between different hole patterns is done by inserting or removing the stamp in question from the corresponding holders. This ensures a high precision of the stamp positions.
- German patent application DE 3427 686 AI a device is disclosed in which a number of radially aligned punch punches are arranged on a punching ring of a punching device and are radially displaceable between a first outer punching position and a retracted passive position by means of internal cam rings are.
- the punch rings can be moved on the shaft along the axis, so that a large number different punching patterns can be generated.
- the cam rings are also moved manually here.
- variable hole punching devices where the operator manually sets up the punching device to change the hole pattern, serious problems can arise if the operator sets up a faulty hole pattern.
- the punching process with a punching device in which an incorrect hole pattern has been set up leads to the destruction of the workpiece, but the punching device itself can also be destroyed, for example if the stamp pattern producing the hole pattern was not set up for a suitable matrix pattern.
- setup by an operator can be very time consuming if the operator does not know exactly what to do or trained operators are required.
- the method according to the invention is a method for supporting the setting up of a punching device with a changeable hole pattern, the punching device having a plurality of punches on a punching tool, which are at least partially optionally adjustable into an active end position in which they punch a hole produce a material or into a passive end position, in which they do not create a hole, and wherein the punching device comprises control means and evaluation means, with the following steps:
- the hole pattern must be determined. This can be done, for example, by reading in data from the operator interface if the operator desires a prefabricated hole pattern.
- a prefabricated hole pattern As an illustration, here is an example from further processing in the printing industry in which the operator inputs a sheet-shaped printing material or a stack of sheet-shaped printing materials is to be punched with a European 2-hole hole pattern or an American 5-hole hole pattern.
- the determination generally only includes the step of reading out the number of holes for such a hole pattern from a reference table, since the number of holes is predefined here. In other cases, the step of determining requires more or less complex calculation and the querying of additional information.
- perforation patterns in sheet-like substrates are required for different types of binding, in particular for wire comb, plastic comb and spiral bindings.
- the number of holes that are to be made in the sheet-like substrates depends, among other things, on the format.
- Stamping tool has four stamps, two of which are movable and four holes are to be made in the material, all stamps must be in an active end position. In this example, if a desired hole pattern consists of only two holes, both movable punches must be in the passive end position.
- a punching tool suitable for this purpose will advantageously have a whole series of stamps, the maximum number of which corresponds to the largest format of sheet-like printing materials to be processed with the punching device, for example 23. If the previous step now determines that 22 holes for a desired hole pattern in If the material is to be introduced, there are two options, namely in that either the stamp on one side or the stamp on the other side of the stamp row is brought into the passive end position. If 18 holes are desired, there are already six different ways to achieve a stamp row of 18 stamps in the active position.
- Which row of stamps should be selected from the six options depends, among other things, on how the sheet-like printing material (s) is or are aligned relative to the stamps of the punching tool. It may therefore be necessary for additional information to be obtained and processed in the step of determining the end position of the stamp.
- the steps of determining are carried out by control means and evaluation means of the punching device, however, the steps of determining are also carried out by control means and evaluating means, which are arranged outside the punching device and / or are assigned to other devices.
- the operator is then shown, depending on the order, how the punching device should be set up in order to prepare the punching device for the next job.
- the operator can quickly check which stamps are already in the correct end position and which stamps have to be changed in the end position. This saves the operator time and the risk that the punches are in the wrong end position is reduced. This is particularly advantageous if the hole pattern depends on other parameters, e.g. From the dimensions of the material and the operator would first have to make calculations as to which stamp should be brought into an active end position and which should be brought into a passive end position.
- the passive end position can also be an end position that is located outside the punching device, e.g. on a shelf when the corresponding stamp is completely removed.
- Operator interface also provides help that the operator can access if required can access to find out exactly what he can do to move the stamps to one of the two end positions.
- Animated graphics that illustrate the movements to be carried out by the operator are particularly advantageously stored in order to achieve the desired result. This makes it possible for an untrained operator to operate the punching device with ease.
- the method also comprises the following step:
- Step d) can be carried out expressly at any point in the process and does not necessarily have to be carried out after steps a) to c) have been carried out.
- measuring units are advantageously connected to the stamps, which indicate the current end position of the stamps to a higher-level controller. This makes it possible to display both the current and the required end position of the stamps on the operator interface, in particular in order to inform the operator which stamps are to be changed and which stamps are already in the correct end position. This saves additional time because the operator does not have to check the end position of all stamps every time.
- the determination could also only include that from a memory in which the last end position of the stamp is stored, it is called up and displayed. In this case, too, the stamps whose end position has yet to be changed could be highlighted. However, this requires that the operator actually put all the stamps in the correct end position during the last job, since the device would lack the possibility of checking the stamp position. On the other hand, such an alternative punching device would be less expensive. In the event that the stamps are removed from the punching tool and stored outside, a measuring device that checks whether a stamp is present or not is sufficient, in this case "installed" corresponds to the active end position and "removed" to passive end position of the stamp.
- the punching tools of the punching device being exchangeable, the method comprises the step:
- the operator interface shows which punching tool must be used to achieve the desired hole pattern and which end positions the stamps of the replaced punching tool should assume. This can e.g. by specifying a part number or another identifier of the punching tools.
- they have electronics which, when the punching tool is installed in the punching device, notifies the controller of the punching device of the configuration of the built-in punching tool.
- the required parameters are obtained from at least one of the following sources when determining the number of holes: a higher-level control, the operator interface, the punching tool.
- the parameters are obtained from mixtures from these sources.
- the higher-level controller can be the controller of the punching device, in which e.g. the order parameters are stored, but it can also be a central control that encompasses the entire machining process of the material, i.e. if punching is only part of the machining process.
- the material could first be rolled, pressed, alloyed or otherwise treated, or comparable processes follow the punching process.
- the machining parameters are typically shared by one central controller
- Processing stations directed, or from processing station to processing station passed. So-called job tickets with which the processing parameters are passed to the processing stations can also be used for offline processing stations if suitable data transmission means are available.
- a particular example of making a complicated part is a book that is printed, die-cut, bound, and trimmed.
- an information source can be the operator interface, on which an operator can enter at least parts of the parameters by hand with suitable input means.
- the punching tool itself can also be one
- Represent information source if it is equipped with appropriate information means, such as a memory from which e.g. the configuration of the punching tool can be read out.
- the step of determining the number of holes comprises determining at least one of the following parameters: the dimensions of the material, the distance from hole to hole, the hole size, the hole shape.
- the material is sheet-shaped printing materials
- the hole pattern is one of the following: the hole pattern for wire comb binding, the hole pattern for spiral binding, the hole pattern for plastic comb binding, the US 3-hole hole pattern, the US 5-hole pattern, the EP 2-hole pattern, the EP 4-hole pattern.
- at least one of the following is taken into account when determining the number of holes: the type of hole pattern, the minimum distance of the hole pattern from the edge of the material, the number of adjustable stamps, the position of the adjustable stamp in the punching tool ,
- an existing axis of symmetry of the material is taken into account in such a way that an existing axis of symmetry of the punching tool is as close as possible to the existing axis of symmetry of the material. This is particularly advantageous when processing materials in which the hole pattern is likewise to be introduced symmetrically to the axis of symmetry of the material. If the position of the punches within the punching tool is predetermined, an existing axis of symmetry of the punching tool will not always lie on the axis of symmetry of the material.
- the axis of symmetry of the punching tool does not match the axis of symmetry of the hole pattern, for example because some of the stamps are in the passive end position and the existing symmetry of all stamps is broken as a result.
- the example of a series of 23 stamps used above is used for illustration. If all these 23 stamps are at the same distance from one another, then the symmetry axis of the punching tool lies in the middle of the twelfth stamp.
- the symmetry axis of the hole pattern and the tool lie one above the other. If the hole pattern is also to be introduced symmetrically into the material, then in this case typically the axis of symmetry of the material and the punching tool lie one above the other.
- a hole pattern with 22 holes is to be made with the same punching tool.
- the axis of symmetry of the hole pattern shifts to the left or right of the axis of symmetry of the punching tool.
- the material must be aligned beforehand so that the symmetry axis of the hole pattern comes to lie above the symmetry axis of the material.
- the punching tool could also be aligned. In both cases, however, it is desirable if the mutual alignment of the punching tool and the material requires the smallest possible travel paths in order to achieve a quick and precise alignment.
- the method additionally comprises the following step: f) Determining a lateral offset of the punching tool to generate a symmetrical hole pattern to an existing axis of symmetry of the material.
- This offset can then be transferred to a controller responsible for the alignment of the punching tool and the material, which carries out a corresponding automatic alignment; on the other hand, the required offset can also be displayed on the operator interface in order to inform the operator that he has to do the corresponding offset manually should realize in order to achieve a good punching result.
- the method additionally comprises the following step:
- step g) is followed by the step:

- FIGS. 2 to 5 show different views of a preferred embodiment of a punching tool with a variable hole pattern 1 and thereby limit the For the sake of clarity, the presentation of essential components. Further, generally known drive and / or guide means and cam disks as well as electrical circuits, which are required for operating the device, are only shown schematically, if so, or are only described in general form.
- FIG. 2 shows a section of a tool roller 41 with three stamps 42 arranged next to one another, which are located in different positions to illustrate the principle of operation of the stamp carrier.
- the tool roller 41 is rotatable about the axis AI, see FIG. 4.
- a punch bar 50 is attached on the circumference of the tool roller 41.
- the stamp bar 50 is fastened by fastening means, not shown, known to the person skilled in the art, e.g. Screws or clamps, advantageously with the aid of centering means, which ensures a reproducible, exact position of the punch bar 50 on the tool roller 41, are fastened to the tool roller 41.
- the stamp bar 50 has a plurality of bores 52, which serve as a guide for the stamps 42.
- the holes in the punch bar are made together with the holes for dies 42 'for a die roller 41' (see FIG. 3) in order to achieve an optimal fit between dies 42 and dies 42 '.
- the designation bore 52 here also includes holes which e.g. by means of wire or die sinking or comparable processes known to the person skilled in the art.
- a stamp carrier 44 consists essentially of a pin 47 and a ring 6, which is arranged around the pin 47.
- the pin 47 has a receiving mechanism 421 on the first side, by means of which a stamp 42 is fastened to the stamp carrier 44.
- the receiving mechanism 421 is a threaded pin 421, the punch 42 having a corresponding internal thread.
- the pin 47 is flat apart from the threaded pin 421 and has a larger diameter than the bore 52. As a result, the first stop surface 60 remains in the assembled state between the punch 42 and the pin 47.
- Stamp carrier 44 assume three different positions, namely a passive end position, an undetermined middle position and an active end position.
- the stamp carrier 44 shown on the left in FIG. 2 is in the passive end position, in which the stamp 42 does not protrude beyond the stamp strip 50 and accordingly cannot contribute to the creation of a hole 2.
- the stamp carrier 44 shown in the middle in FIG. 2 is in the undefined middle position, in which the stamp carrier 44 is not in contact with the corresponding stops 51 or 412 on any of the stop surfaces 60, 65.
- stamp carrier 44 None of the stamp carrier 44 should be in this position during the operation of the tool roller 41, since the stamp carrier 44 is not secured in this position and, due to the vibrations and movements during operation of the tool roller, could move so far that the stamp 42 over or under the punch bar 50, thereby contributing to an undesired hole 2 or correspondingly not producing a desired hole 2.
- the stamp carrier 44 shown on the right in FIG. 2 is in the active end position, in which the stamp 42 projects beyond the stamp bar 50 and accordingly contributes to the creation of a hole 2.
- the stamp carrier 44 is connected to an actuating element 47 '.
- the adjusting element 47 ' is an adjusting screw 47'.
- the set screw 47 ' is guided in a thread 414 in the tool roller 41.
- the thread 414 is located in a plate, not shown, which is fastened to the tool roller 41.
- the stamp carrier 44 is held by the return spring 45 in contact with the surface 47 "of the set screw 47 '.
- the surface 47" of the set screw 47' is spherical so that the contact point consists approximately of one point, causing wear on the stamp carrier 44 and Set screw 47 'can be reduced.
- stamp carrier 44 and set screw 47 ' are hardened at least in this area in order to further reduce wear.
- the set screw 47 ' also has a step between a cylindrical outer surface and the thread 414.
- the stamp carrier 44 follows the return spring 45 due to the spring tension to the passive end position of the stamp carrier, at which the ring 46 abuts the second stop 412. If the adjusting screw 47 'is unscrewed further, the adjusting screw 47' initially loses the
- a screw attachment 48 is provided which allows an operator to change the position of the adjusting screw 47' and thus the stamp carrier 44 along its axis A3 in the direction of movement, which is identified by the arrow P1.
- the axis A3 does not have to coincide with the axis of rotation of the set screw 47 ', in practice this would only be achieved with an undesirably high level of effort anyway, but it is also unnecessary since the rotary movement of the set screw and the vertical displacement of the stamp carrier are not coupled to one another ,
- the screw attachment 48 is shaped in accordance with a suitable tool, for example a torque wrench.
- the screw attachment 48 is cut to length so that it does not protrude over the circumference of the tool roller 41 in contact with the stop 415, so that there is no damage to the stamp carrier 44 or to one another Arranged die roller 41 'can arise.
- a return spring 45 is arranged around the pin 47.
- the return spring is supported on the one hand on the underside of the stamp bar 50 and on the other hand on the ring 46 of the stamp carrier 44.
- the second stop surface 65 is provided on the other side of the ring 46 and is pressed against the stop 412 in the passive end position of the stamp carrier 44.
- the stop 412 is part of the surface of the interior of the tool roll 411, it is immediately clear to the person skilled in the art that specially provided stops can also be provided for this purpose, which are not part of the surface of the interior of the tool roll 411.
- stamp carrier 44 has been described above as consisting of various parts, it is clear to the person skilled in the art that the stamp carrier 44 is typically a one-piece component. In fact, it is also conceivable to assemble the stamp carrier 44 from the individual elements 421, 46, and 47. Moreover, it is not necessary for the pin 47 or the ring 46 to have a cylindrical cross section, since the stamp carrier 44 itself is not rotated during the up and down movement.
- the operator can now create different hole patterns 3 by bringing the corresponding punch carrier 44 into the corresponding active or passive end position and fixing it there to the stops.
- the torque used for this purpose is limited, for example by a torque wrench, a very high precision and reproducibility of the end position of the stamp 42 can be achieved from the fit between the corresponding stops 51, 412 with the stop surfaces 60, 65 of the stamp carrier 44. This is particularly important for the active end position in order to avoid damage to the dies 42 ′ and to produce high-quality holes 2.
- FIG. 3 shows an exemplary tool roller 41 and matching die roller 41 ', which is rotatably mounted about an axis A2 and illustrates the special case of adapting a hole pattern 3 for a wire or plastic comb binding to the format of a sheet-like printing material 1
- the punches 42 are attached equidistantly in three areas 491, 492, 493.
- the stamps 42 are not assigned to a stamp carrier 44, but are connected directly to the stamp strip 50, namely screwed into the stamp strip 50 by means of a thread 431.
- alternative fastening means can be expressly implemented, and in the central area 493 the punches 43 can also be connected directly to the tool roller 41 instead of the punch bar 50.
- a change in such a hole pattern LB1, LB2, LB3, LB4, LB5 can be achieved in that the punches 42 adjoining the central area in the first and second outer areas 491, 492 also from inside to outside an active position. In principle, however, it is also sufficient to bring only the stamps 42 in the first and second regions 491, 492 into a passive end position, which are in the vicinity of the outer edges K1, K2 of the sheet-like printing material 1. All other stamps 42 can always be in an active end position.
- a corresponding die 42 ' is assigned to each punch 42, 43.
- the inside of the die 43 ' represents a passage to the inside of the die roll 411' through which the punching waste can be transported away.

- Matrix roller 41 'and tool roller 41 are arranged in a housing 401.
- the tool roller 41 is connected to the motor 402 via a tool shaft 460,
- the functional position of the tool shaft 460 is monitored by a sensor 480 and transferred to a higher-level control 500, which also drives the device by activating the motor 402.
- a marking 481 is provided on the tool shaft 460, which makes it possible to determine the functional position of the tool shaft 460, for example in the form of a perforated diaphragm 481.
- the sensor 480 is an optical sensor 480. Also a magnetic sensor, among others or other coding or a corresponding sensor conceivable to determine the functional position of the tool roller 41.
- measuring units 510, 512 are provided on the stops 51, 412. These measuring units 510, 512 deliver a signal when the stamp carrier 44 rests with its stop faces 60, 65 on the corresponding stops 51, 412.
- the measuring units 510, 512 are, for example, resistance-dependent sensors, in which a circuit is closed by the presence of the stamp carrier stop surfaces 60, 65.
- capacitive, magnetic, optical or other sensors are also conceivable, as are known in large numbers to the person skilled in the art from the prior art.
- the measuring units 510, 512 are connected to the controller 500 and inform the controller 500 whether the plunger 42 is in the active or passive end position. This information is used to inform an operator of the end position via an operator interface 520, 530 and possibly to stop the punching device if the active or passive end positions determined by the measuring units 510, 512 do not match the required active or passive end positions.
- FIG. 5 shows a punching tool 40 with 23 stamps 42 in a row, and a material 1 which has been punched into a hole pattern 3 which corresponds to the stamps 42 which were in an active end position.
- the schematic representation of punching tool 40 and sheet-shaped printing material 1 with hole pattern 3 in FIG. 5 is a possible embodiment of a display on display means 530.
- the numbering of stamps 42 on display means 530 from 1 to 23 corresponds to a numbering, which the operator also finds on the actual stamps 42 in the stamping tool 40, so as to create an association.
- a different assignment can be a color coding, although color coding can have defects known to the person skilled in the art, such as a lack of distinctive character in the case of color blindness of the operator.
- the border designated with the reference symbol 493 indicates the punches 43, which cannot be moved on the punching tool 40, that is to say always remain in the active end position.
- the filled rectangles symbolize the punches 42, 43 which must be in the active end position for the hole pattern 3, the unfilled rectangles symbolize the punches 42 in this illustration, which should be in a passive end position.
- the stamps 42a identified by the reference symbol 42a which would reach the area of the outer edges K1, K2 of the sheet-like printing material 1.
- the stamps 42 are additionally highlighted on the display means 530, which are in accordance with the information from the controller 500 are not in the required end position.
- the controller 500 obtains this information either from measuring units 510, 512, if these are present, or from the memory in which the last setting of the stamp 42 is stored. Alternatively, an operator could also enter the current end position of the stamp via input means 520.
- the input means 520 are input means 520 known from the prior art, such as a mouse, stylus, keyboards, etc.
- the display means 530 is typically a screen.
- the display means 530 can also indicate the offset ⁇ that occurs between the center line MW of the punch 40 and the center line MB of the sheet-like printing material. This offset could then be set manually by an operator, on the other hand the control 500 can also pass on the required offset ⁇ to suitable actuating means, not shown, which carry out an exact alignment between sheet-like printing material 1 and punching tool 40.
- the controller 500 determines the parameters "TOOL_MAX_HOLES", namely the maximum number of punches 42, 43 of the punching tool 40, "TOOL_FLXED_HOLES”, namely the number of stationary punches, it being assumed that stationary punches are always arranged in the center of the tool are "TOOL PITCH”, namely the hole spacing measured from hole center to hole center, and "TOOL_HOLE_SIZE”, namely the hole size directly from the punch 40.
- the punch 40 has an electronic identifier, not shown, which is used when the punch 40 of the control is inserted 500 of the parent punching device is made available and, in addition to the parameters described above, may also contain additional data, e.g. number of work cycles already performed, production date, part number, etc.
- the controller 500 takes over other data from a memory in which a system configuration is stored, in particular the parameter , 'BINDING_MIN_MARG1N'', namely the minimum edge distance for the respective binding application measured from the binding edge to the center of the hole.
- a system configuration in particular the parameter , 'BINDING_MIN_MARG1N'', namely the minimum edge distance for the respective binding application measured from the binding edge to the center of the hole.
- the control system could have obtained information about the material properties, for example from a higher-level control system that coordinates the entire production of a book.
- parameters can also be obtained from such a higher-level control system, or can be entered directly by the operator on the user interface 520, 530 using the input means 520.
- the parameters that are still missing in this exemplary embodiment are "JOB PAPER SIZE”, namely the desired paper size, "JOB_PITCH”, namely the desired hole spacing from hole center to hole center and "JOB_HOLE_SIZE”, namely the desired hole size.
- the punch 40 may have to be replaced if the required hole size "JOB_HOLE_SIZE” or the desired hole shape and the distance from hole to hole "JOB PITCH” do not correspond to what the built-in punch 40 offers, ie "TOOL_HOLE_SIZE” or "TOOL_PITCH”.
- a corresponding check of the control 500 leads to the operator being informed on the display means 530 which punching tool 40 is to be installed in order to be able to implement the desired hole pattern 3.
- control and evaluation means 500 determine the end positions of the punches 42, that is to say whether the punches should be in an active or passive end position.
- the controller calculates the following values for this:
- TOOL_VARIABLE_HOLES TOOL_MAX_HOLES - TOOLJFLXED HOLES Number of adjustable stamps "back":
- INTEGER TOOL_VARLABLE_HOLES / 2
- RETRACTED DIES TOOL MAX HOLES - JOB HOLE COUNT Number of stamps 42 in the passive end position "rear”, ie stamps 1 to H:
- TOOL_MAX_HOLES - V to TOOL_MAX_HOLES: V TOTAL (RETRACTED_DIES / 2 + 0.5).
- the control and evaluation means 500 generate a display of display means 530, for example: "Please check the tool setting and make sure that the punches 1-3 and 21-23 are in the retracted state", alternatively or additionally a suitable graphic can be provided on the display means 530, which shows the required end position of the stamp as shown in FIG. 5.
- the control can use the measuring units 510, 512 to determine which punches 42 are in which end position
- the display means 520 can additionally show the operator which punches 42 require a change in the end position.
- control and evaluation means 500 determine the offset ⁇ between the center line MW of the punching tool 40 and the center line MB of the sheet-like printing material 1 according to the formula (RETRACTED_DIES 12 - GANZZAHL (RETRACTED_DIES / 2)) * TOOLJPITCH.
- This offset ⁇ becomes either displayed to the operator via the display means 530 or forwarded directly to suitable actuating means, not shown, which compensate for the offset ⁇ .
- the method described here to support the setting up of a punching device with a changeable hole pattern is used in all punching devices with a changeable hole pattern, regardless of the material to be processed, i.e. for punching devices for metal sheets, textiles, paper, plastic foils, cardboard etc. It does not matter whether a single material or a stack of materials can be processed simultaneously.
- the method described here is used in particular to support the setting up of a punching device with a changeable hole pattern in the inline further processing of printed products from digital printing machines with a suitable integrated punching device with a changeable hole pattern. It can also be used in all copiers / printers in which sheet-like substrates are post-processed, in particular also in offline processing.
- the stamp carrier for a stand-alone device which introduces a stamping pattern into stacks of sheet-shaped printing materials and is intended to be as user-friendly as possible.
