EP2363364B1 - Sheet guidance device, production system for printed products with a sheet guidance device and method for producing printed products - Google Patents

Description

The invention relates to a production system for printed products according to claim 6 and a sheet guiding device according to claim 1 and to a method for producing printed products according to claim 12.

State of the art

From the state of the art for the production of printed products such as brochures, booklets, books, signatures or the like. Pocket folding machines and Schwertfalzmaschinen known. The combination of pocket folding machines with Schwertfalzmaschinen is common as Kombifalzmaschine. In this process, parallel folds are folded in pocket folders and cross breaks in the subsequent knife folders. The sheet passes through at least the following stations in the feed-through direction of the combination folding machine: feeder, transfer table, pocket folder, knife folder, delivery arm.

In this case, in a feeder, sheets are laid in portrait format, parallel fractions are folded in a first folding station in pocket folders, and cross-folds are folded in a subsequent folding station in knife folders. The DE 10 2006 055 301 A1 shows Kombifalzmaschinen with a plurality of Taschenfalzwerken and nachranging arranged Schwertfalzwerken.

The construction of a Taschenfalzmaschine with a variety of Taschenfalzwerken goes out of the DE 10 2004 041 471 A1 out. In this case, sheets are laid in portrait orientation in a feeder, parallel breaks are folded in a first folding station in pocket folders, and further parallel breaks are folded in a subsequent second folding station in pocket folders. The second folding station is rotated by 90 ° to the first folding station. A respective pocket folder consists of a folding pocket and three folding rollers, which are arranged in two pairs of folding rollers.

The WO 97/24284 A2 discloses a manufacturing system with a sheet guiding device, which alternately directs the sheets on two transport paths, ie, the function "sorting single stream" revealed.

The US 2005/224205 A1 however, discloses a manufacturing system for webs, not for bow. Partial switches are switchable between two switch positions and direct a previously cut longitudinal path on one of two transport paths. Switching of the sub-points during rail transport is not possible because it is an endless track. Thus, the function "double flow for webs" is disclosed here. This revelation also has the US 3307441 A ,

From the prior art no sheet guiding device emerges, which alternatively transports sheets in multiple stream and can sort sheets in single stream.

A transverse application of the folded sheet requires an adjustment of the folding schemes and offers additional ways of saving paper and time. According to the prior art, the speed problem has been shifted to the second folding station when Queranlegen. Although the reduced run-in length came into play in the feeder and in the first parallel folding unit, the full infeed length had to be transported again on the 90-degree turned second station. Therefore, a very high speed of the second station was necessary, which could lead to folding problems and quality reductions.

Combinations of printing machines with folding machines are also known from the prior art. So revealed the DE 195 23 881 A1 a rotary printing press with downstream processing unit, which has different folding stations, namely folding cylinder and Schwertfalzwerke. From the DE 196 29 072 A1 goes out a digital printing machine with downstream folding machine, the folding machine has Taschenfalzwerke.

Even with such manufacturing systems there are speed problems. In printing machines, either webs or sheets are printed at high speed with a small distance. Due to speed limits in the subsequent folding machine, the printing press can only be operated at reduced speed in a direct coupling of printing press and folding machine.

task

The object of the present invention is therefore to increase the productivity of the manufacturing process in the production of printed products, in particular signatures, brochures, newspapers and books, without increasing the speed of a folding machine used in the production.

This object is achieved by a production system for printed products with the features of claim 6 and by a sheet guiding device with the features of claim 1 and by a method according to claim 12.

The production system for flat printed products according to the invention has a printing press and a - as seen in the transport direction - subsequently arranged, i. downstream intermediate processing and transfer station. Further below, i. farther downstream, at least one folding station, in particular a pocket folding station, is arranged. The printed products are transportable through the manufacturing system in a continuous, continuous flow of material, i. there is no interim storage with required intervention of the machine operator for re-investment. Continuously, this does not mean that the printed products have to be transported unequally. According to the invention, a sheet guiding device with a switchable sheet diverter is arranged between the intermediate processing and transfer station and the at least one folding station. This serves to pass the printed products onto a first or a second transport path. Through the use of the sheet guiding device is achieved in an advantageous manner that the at least one folding station no longer represents the production bottleneck (so-called bottleneck or "bottle-neck") of the manufacturing system. Since it is made possible by the sheet guiding device to guide the two-dimensional printed products either on a first or a second transport path, and to supply further processing, the processing speed of the at least one subsequent folding machine no longer has to be increased in order to increase the production output of the production system.

In a particularly advantageous and therefore preferred embodiment, the printing press is a digital printing press. This ensures that the manufacturing system can produce print products with different content or printed products that consist of several differently printed single sheets in succession and without a great deal of time for machine conversions.

In a preferred embodiment, the printing machine is designed as a web-fed printing machine and the intermediate processing and transfer station has a cross-cutter for dividing a printing material web into individual sheets. This can advantageously the folding accuracy of Bogenfalzstationen and the cost advantages of Material costs of a printing material web in contrast to a substrate sheet stack can be combined.

In a further advantageous embodiment, the intermediate processing and transfer station can have a collecting device for stacking individual sheets. This may for example be a so-called drum collector, which is optionally equipped with a glue applicator for connecting the single sheet. The individual sheets may also be single sheets with different print content, which together should form a printed product, for example a signature. The stack formed by the collecting device can then be transferred to a subsequently arranged folding station and folded there to a brochure.

• Eine Queranlage der zu falzenden Bogen am Anleger bzw. ein Bereitstellen von Bogen im Querformat durch den Querschneider der Zwischenbearbeitungs- und Überleitstation zusammen mit einer Bogenleitvorrichtung vor der zweiten Falzstation. Durch die geringere Einlauflänge des Bogens bei gleicher Maschinengeschwindigkeit liegt die Leistungssteigerung abhängig vom Bogenformat bei etwa 30 Prozent.

In a first embodiment (see Fig. 6b ) are the transport directions of the first and second transport path parallel to each other and in a plane and the printed products can be fed to the transport paths of a subsequent Taschenfalzstation. In this embodiment, the individual sheets of the sheet guiding device can be alternately passed to the first and second transport path, so that the sheets can enter into the subsequent Taschenfalzstation with a larger arc distance. This advantageously allows the folding stations to operate at a lower speed while maintaining high productivity, which in turn results in even higher folding accuracy.
The productivity of Taschenfalzmaschinen can thus be significantly increased by the use of a sheet guiding device according to the invention. Two aspects contribute significantly to this:

• A transverse arrangement of the sheet to be folded at the feeder or a supply of sheets in landscape format by the cross cutter of Zwischenbearbeitungs- and transfer station together with a sheet guiding device before the second folding station. Due to the lower run-in length of the sheet at the same machine speed, the performance increase depends on the sheet format at about 30 percent.

The sheet guiding device makes it possible to guide the folded sheets alternately on two (or more) transport paths, to align parallel to two (or more) rulers and the second folding station to transport. Since twice as many folded sheets can be transported in this way, the speed of the second station can thus be reduced by half. By the cross run of the sheet in the first parallel folding at constant machine speed now on the one hand productivity is significantly increased and on the other hand, improved by the low speed of the second station, the folding quality and the folding process made even more stable.

In a second embodiment (see Fig. 6a ), the transport directions of the first and second transport path are arranged substantially at right angles to each other, can lie in substantially parallel planes or in one plane, and the printed products can be fed on one transport path of a first folding station and on the second transport path of a second folding station. That is, downstream of the one transport path is a first folding station and downstream of the second transport path is a second folding station. The two folding stations can be operated either in parallel. Or only one of the two folding stations is used for the production of the printed products, while the second folding station can already be preset for a subsequent production order. Such a ausgestaltetes manufacturing system is particularly advantageous when it is the printing press to a digital printing press, as this reduces the machine downtime of the manufacturing system between two different production orders to a minimum or can be completely eliminated.

In an advantageous embodiment of one of the manufacturing systems described above, the sheet guiding device has a guide device for passing a printed product onto the second transport path, in other words: the guide serves to bridge over the first transport path. Possible embodiments of the guide will be described below.

The invention also relates to a method for producing printed products of n different types, where n is equal to 1,2,3 ... a natural number. The method is carried out in a manufacturing system comprising a digital printing machine, a sheet folding machine and a sheet guiding device, which in particular as above described, may be executed. The sheet guiding device is designed as a switchable sheet diverter with n switching positions for passing the printed products on one of n subsequent transport paths. The method comprises the following steps: First, the printing of a substrate with an n-th print content. If the printing material is a printing material web, it is subsequently separated into individual printing material sheets. Then the printing material sheets are folded into signatures. These are then passed through the sheet guiding device on one of the n transport paths on. Thus, for example, a first signature, which has been folded from printing material sheet, which have a first printing content, directed to the first transport path. If an n-th printed product consists of a plurality of signatures, the above-described steps are repeated and the signatures are collected, for example in a cantilever. All of these steps are also performed to produce the other types of printed products. It is not necessary that a complete n-type product is first completed before a different type of print product is produced. Such parallel production of various types of printed products is enabled by the sheet guiding apparatus having a sorting function.

Such a method thus makes it possible to produce different products on the same production line and to design them physically separate from each other. As a result, the productivity of the manufacturing system used can be increased in an advantageous manner. It is no longer necessary to maintain multiple manufacturing systems for different products, but rather a manufacturing system is sufficient, whereby even this only a production system for order preparation must be preset. Thus, the effort for Voreinstellarbeiten can be reduced.

In an advantageous embodiment of the method according to the invention, the print content, which is printed by the digital printing press on the substrate, an identification feature for identifying the type of printed product (such as a barcode, eg bar code or DataMatrix code). This identification feature is read by a detection system, which is located upstream of the sheet guiding device and causes a control of the sheet guiding device.

If, for example, it is determined by the detection system that the printed product is a printed product of the first type, then the sheet guiding device is adjusted to its first switching position so that the printed product is directed onto the first transport path. It is also advantageous to provide additional monitoring and control systems (for example bar code readers and / or cameras) in the course of further processing for monitoring the product quality.

In an advantageous development of the method according to the invention, printed products of two types are produced, the printed product of the first type being a main print and the second printing product being a reprint, a so-called reprint. If a malfunction occurs in the main production, which leads to individual products not being able to reach the delivery station of the printed products, or only by default, then either the machine operator or a higher-level machine control can promptly reprint them. The reprint is produced by the same manufacturing system. However, the sheet guiding device is controlled so that the reprint is physically separated from the main production and directed to the second transport path, so that the reprinting is designed separately from the main pressure. The reprint can later be manually fed to the print product at the correct location. In contrast to the previously named sequential processing of main pressure and holding pressure, this variant of the method according to the invention significantly increases the productivity of the production system used.

In an alternative development of the method according to the invention, printed products are produced in different versions. These may be, in particular, different language versions (eg German, English, French) or different country versions (eg Great Britain, USA, Australia) or different variant versions (eg manual variant pneumatic, variant hydraulic) or different container size versions (eg medicament with 20 tablets or 100 tablets). These various versions are printed on the digital press in any order and subsequently conveyed through the sheet guide to a transport path associated with each version directed and sorted. After folding, the different versions of the signatures are separated into versions and can thus be forwarded separately to the end user. This method has the advantage that a larger number of variants can be manufactured inexpensively without loss of productivity. This is particularly important for the production of printed products in small to medium runs.

The sheet guiding of the manufacturing system with the function of a curved switch can be advantageously carried out as described below sheet guiding device.

The sheet guiding device can be controlled mechanically or pneumatically in an advantageous manner.
The sheet guiding device can be integrated into a sheet folding machine in various ways. It can be attached to the first folding station, it can be attached to one of the first folding station downstream transfer table or it can be designed as a standalone machine module with structure and rollers for moving the module, which can be positioned between the first folding station and the transfer table.
The sheet guiding device can also be used for true double flow or multiple flow, in which the first folding unit cuts the sheet (separating cut / middle cut): The sheet divider can be split in the middle for processing a double flow and receives two positions that can be rotated against each other: Through Switching over to this permanent position, the first partial flow of the double flow is aligned on the first ruler and the second partial flow of the double flow on the second ruler and transported on to the second folding station. For processing a multiple flow, which is generated by more than one separation cut in the folded signature, the Bogenweiche is segmented. In other words: the curved switch consists of a plurality of partial switches, which are individually controllable. The sub-points are controlled grouped so that the extension of a group of sub-points approximately corresponds to the extension of a signature across the sheet transport direction.

Conventional folding machines are optimally suited for the use of the sheet guiding device. To shrink the sheets transversely may require a pocket folder that is one size larger than the format class of the sheet. The necessary sheet guiding device can be easily retrofitted in the usual folding machines.

The described invention and the described advantageous developments of the invention are also in any combination with each other advantageous developments of the invention.

With regard to further advantages and advantageous embodiments of the invention, reference is made to the dependent claims and the description of exemplary embodiments with reference to the accompanying drawings.

As in Fig. 1 illustrated, the sheet guiding device 1 has a curved switch 10, which consists of a right part of the dividing part 10.1 and a left part of the dividing element 10.2. By a switching movement 19, which is triggered by a drive 12, in particular a pneumatic cylinder, the curved switch 10 can be moved between their various positions. In the presentation of Fig. 1 is the curved switch 10 in its second position and in the sheet transport direction T supplied sheet is forwarded via the guide 17 to a second transport path 3 (not shown). In Fig. 1 a first embodiment of the guide 17 is shown, which has a baffle 14, telescopic hold-down rods 16 and upper tuyeres 15.1 and lower tuyeres 15.2. The blown air introduced through the tuyeres can be regulated in their air volume, for example, a continuous air or a clocked blown air can be provided so as to apply an additional thrust force on the arc in the guide 17 and thus secure transport into the first transport path 2 or To ensure second transport path 3. The blast air provided at the upper tuyeres 15.1 also reduces the friction between the bow and baffle 14, since the bow can slide on a stream of air.
In one embodiment, not shown, the baffle 14 may be provided with Venturi nozzles.

The transfer movement of a sheet 1000 through the sheet guiding device 1 to the first transport path 2 or the second transport path 3 is in the FIGS. 2a and 2 B shown in more detail. In Fig. 2a the sheet diverter 10 is in a first switching position and a sheet 1000 is passed from the first Taschenfalzstation 102 coming to the first transport path 2 of the transfer table 103. In the sheet transport direction T upstream of the curved switch 10, at least one sensor 11 is arranged, which detects the entry or exit of a sheet 1000. It can also be provided a sensor to detect the shrinkage and to detect another sensor to leak. In addition, this sensor 11 or an additional sensor (not shown) may be provided to read a bar code located on the sheet 1000. At each detection, the sensor 11 sends a control pulse to the (in the FIGS. 2a and b not shown) pneumatic cylinder, which a Switching movement 19 in the curved switch 10 effect.
The situation after the executed switching movement 19 is in Fig. 2b illustrated: The curved switch 10 is in its second switching position and a sheet 1000 is passed through the grid 13 of the guide 17 to the second transport path 3 of the transfer table 103. The telescopic hold-down rods 16 ensure that the sheet 1000 does not lift off, and is safely transported to the second transport path 3. The hold-down rods 16 allow by their telescopic design a simple adaptation to the positions of the first Ausrichtlineals 4 and the second Ausrichtlineals 5 and thus to the format of the sheet 1000th

• ein Gitter 13 aus gespannten Seilen bildet die Transportebene zum Überleiten eines Bogens 1000 von der Bogenweiche 10 auf die zweite Transportbahn 3. Ein zweites Gitter 13 aus gespannten Seilen bildet eine leicht schräge Leitfläche zum Überleiten von Bogen 1000 von der Bogenweiche 10 auf die erste Transportbahn 2. Ein auf die zweite Transportbahn 3 übergeleiteter Bogen 1000 (nicht dargestellt) wird mittels der Schrägrollen des Überleittischs 103 in Bogentransportrichtung T weiter transportiert und dabei an dem ersten Ausrichtlineal 4 ausgerichtet. Das zweite Ausrichtlineal 5, welches parallel zum ersten Ausrichtlineal 4 angeordnet ist, ist in Fig. 3 nicht dargestellt.

Fig. 3 shows a three-dimensional overview of the sheet guiding device 1 with a guide 17, in the second embodiment:

• a grid 13 of tensioned cables forms the transport plane for passing a sheet 1000 of the curved switch 10 on the second transport path 3. A second grid 13 of tensioned cables forms a slightly inclined guide surface for passing sheets 1000 of the curved switch 10 on the first transport path. 2 A sheet 1000 (not shown) transferred to the second conveying path 3 is further transported in the sheet transporting direction T by means of the inclined rollers of the transfer table 103 and thereby aligned with the first aligning ruler 4. The second alignment ruler 5, which is arranged parallel to the first alignment ruler 4, is in FIG Fig. 3 not shown.

In a third embodiment, the guide 17 may be designed as a strip line (not shown).

Out Fig. 4 This results in the connection of the sheet guiding device 1 to the transfer table 103. This allows good accessibility when changing blades in the first pocket folding station 102 (in FIG Fig. 4 not shown), as by removing the transfer table 103, the sheet guiding device 1 is removed with and the range of the cutter shafts of the first Taschenfalzstation 102 is thus freely accessible. As in Fig. 4 indicated, the guide 17 can perform with its baffle 14 a pivoting movement 20 to make the first transport path 2 accessible and in this way a manual disposal of entangled, trapped sheet 1000, so-called stoppers, to enable. The pivoting movement 20 can be effected manually or be effected or supported by any actuator, for example as in Fig. 4 represented by a pneumatic cylinder. If the movement is only supported, a gas spring can be provided.

In Fig. 5 a sheet folding machine 100 is indicated, with a first Taschenfalzstation 102, the sheet guiding device 1 and a transfer table 103, which is designed as a Schrägrollentisch. In front of the first pocket folding station 102 is a sheet feeder 101; to the transfer table 103 is followed by a second Taschenfalzstation 104, (see. Fig. 4 ).

If a double stream of sheets 1000 is to be processed in the sheet folding machine 100, then in the first pocket folding station 102 there is a rotary knife for carrying out a separating cut or center cut. A sheet 1000 coming from the feeder 101 is thereby halved and two parallel sheet streams leave the first pocket folding station 102 and reach the area of the diverter 10 of the sheet guiding device 1. For passing the first sheet flow onto the first conveying path 2 and the second sheet flow onto the second conveying path 3 the drive 12 is put out of operation to carry out a switching movement 19 of the curved switch 10. The right part of the sub 10.1 and the left sub 10.2 are then rotated manually against each other so that one of the two part 10.1 and 10.2 is located in a first position and a sheet of current to the first transport path passes and the other of the two partial points 10.1 and 10.2 in the second position and forwards a sheet flow to the second transport path 3. The two sub-branches 10.1 and 10.2, which together form the curved switch 10, are in the FIGS. 1 and 3 indicated.

Shown in the figures, the curved switch 10 is only in its first and second positions. However, it can still be provided a further position in which waste sheets archived 1000 can be discharged.

Fig. 6a shows a first variant of a manufacturing system 999 according to the invention: from a feeder 101, a printing material is fed to a printing machine 200, printed there. The printing machine 200 can be designed as a web-fed printing press or alternatively as a sheet-fed printing press, as shown. If the printing substrate is a printing material web, a cut of the web into individual sheets takes place subsequently in the intermediate processing and transfer station 201; if the printing material is already in the feeder 101 in the form of individual sheets, no cutting takes place in the intermediate processing and transfer station 201. The intermediate processing and transfer station 201 may additionally be equipped with a collecting device, which optionally forms sheet stacks from single sheets. Downstream of the intermediate processing and transfer station 201 is a sheet guiding device 1, which has a curved switch 10. This can be carried out as above. By this sheet guiding device 1, it is possible - as indicated by the arrows - to feed the sheet or stack either at an angle of 90 ° via a transfer table 103 a first Taschenfalzstation 102, where the sheets or stacks are folded. The signatures generated there can be laid out in a boom 105 arranged downstream. Alternatively, the sheets or stacks from the intermediate processing and transfer station 201 coming from the sheet guiding device 1 can be further transported straight into a second Taschenfalzstation 104 and experienced there folding. Downstream of the folding station 104 is a boom 105 for laying out the signatures. In a first operating form, the sheet guiding device 1 is controlled in a clocked manner so that sheets or stacks coming from the intermediate processing and transfer station 201 are forwarded alternately to the first pocket folding station 102 or to the second pocket folding station 104. Since the first pocket folding station 102 and the second pocket folding station 104 receive the sheets with different orientation, only different products can be produced. In a second operating mode of the manufacturing system 999, only one of the two Taschenfalzstationen 102, 104 used for the processing of printed products, while the other of the two Taschenfalzstationen 104, 102 can already be prepared for a subsequent order.

In Fig. 6b an alternative embodiment of the manufacturing system 999 according to the invention is shown. As already on the basis of Fig. 6a described, a substrate is printed by a printing machine 200 and formed in a Zwischenbearbeitungs- and Überleitstation 201 single sheet or stack. From a downstream arranged sheet guiding device 1, the stacks or sheets can be placed on several alternative transport paths, which are located in a plane and feed the sheet or stack via a transfer table 103 a Taschenfalzstation 102, where the sheets or pile experience a fold. Downstream of the pocket folding station 102, a boom 105 is arranged, in which the finished printed products can be designed parallel to each other.

In Fig. 6c an alternative embodiment of the manufacturing system 999 according to the invention is shown. As already on the basis of Fig. 6a and b described, a substrate is printed by a printing machine 200 and formed in a Zwischenbearbeitungs- and Überleitstation 201 single sheet or stack. From a downstream arranged sheet guiding device 1, the stacks or sheets can be placed on several alternative transport paths, and the sheets or stacks can be transported either straight ahead, to the right or to the left. The onward transport to the left and straight ahead was already on hand Fig. 6a described. The further processing with transport to the right corresponds to the further processing, which at the hand of Fig. 6b has been described. The number of illustrated transport paths with alignment rulers in the area of the transfer tables 103 is to be understood as an example.

In Fig. 7 a third embodiment of a manufacturing system according to the invention 999 is shown. Coming from a feeder 101, a printing material is fed to a printing machine 200 and printed there. If the printing substrate is a printing material web, individual sheets are subsequently produced in an intermediate processing and transfer station 201. If individual sheets are already created by the feeder 101, then the intermediate processing and transfer station 201 is not required. In the downstream Taschenfalzstation 102, the sheets are folded into signatures. Hereinafter, the signatures of a sheet guiding device. 1 sorted and supplied on different transport paths of a transfer table 103 a boom 105 and designed there. In the exemplary representation of Fig. 7 three parallel transport paths of the transfer table 103 are provided, so that in the boom 105 three stacks of finished products are produced. The number of illustrated transport paths is to be understood as an example. It can also be provided only two or more than three transport lanes.
The products can be different versions. In an alternative embodiment, which in Fig. 7 not shown, may be between the transfer table 103 and the boom 105, similar to the Figures 6a and 6b shown, another Taschenfalzstation be arranged to produce cross breaks. This in Fig. 7 999 shown manufacturing system can be particularly advantageous for the production of printed products in different versions. Alternatively, the manufacturing system 999 may also be used to produce a main pressure and a reprint on the same production line.

In Fig. 8 a further embodiment of a manufacturing system 999 according to the invention is shown. As already on hand of the Fig. 7 Falzprodukte be generated by a Taschenfalzstation 102. Instead of providing a sheet guiding device 1 with three switching positions, three sheet guiding devices 1 arranged one behind the other are used. If a product is not passed from the upstreammost sheet guiding device 1 to the first transport path, it is transported further into the next sheet guiding device 1. If a product is not passed from the central sheet guiding device 1 to the second transport path, it is transported further into the last sheet guiding device 1. From this, the product can then either be placed on the third transport path or discharged. If no Ausschleusmöglichkeit be provided, it can be dispensed with the last sheet guiding device 1. Instead of a plurality of sheet guiding devices 1, only one sheet guiding device 1 with a plurality of sheet deflectors 10, 10.1, 10.2 arranged in series can be used.

In Fig. 9 a further embodiment of a manufacturing system 999 according to the invention is shown. This represents a further education in Fig. 7 variant described.

After the products have been folded in the pocket folder 102, two parting cuts occur, thereby dividing the product into three parts. These three parts are transported on as a multiple stream. The following sheet guiding device 1 has for this purpose a segmented sheet diverter 10, which has three part switches 10.1, 10.2 and 10.3. Each of these sub-points can be controlled separately (by a machine control, not shown here). If necessary, a respective partial diverter can be formed from several segments. If the curved switch 10 has, for example, six segments of the same format, then two segments are each grouped in order to form a partial switch. A respective stream of the multiple stream is directed to one of the three transport lanes.
Such a segmented curved switch 10 for separating a multiple current can also be used advantageously in one of the previously described embodiments. If several sheet guiding devices 1 (as in Fig. 8 shown) in series and with segmented curved turnouts 10.1, 10.2 (as in Fig. 9 equipped), so there are numerous possibilities of sheet guiding and sorting possibilities.

In variants not shown, the web-shaped substrate can be printed in a separate printing press. The in the FIGS. 6 to 9 illustrated printing machine 200 is then omitted and by the illustrated feeder 101 (unwinding), a printed web is provided.
