These can be aligned in a same continuous channel with their ends, or as in D7d - reducing susceptibility to vibration - with their ends offset by 180 ° to each other in two mutually offset by 180 ° channels (or channel sections) be arranged ("stacked"). This is advantageous if, with simple handling, an arrangement of printed images in the circumferential direction should be ensured without restriction by a joint line. In a likewise advantageous embodiment, two printing forms extending over the entire length but only reaching half the circumference can be arranged in two channels offset by 180 ° ( D7c ). The latter is advantageous if, with simple handling, an arrangement of printed images in the longitudinal direction should be ensured without restriction by a joint line. This may be the case, for example, if, in addition to an even number, an odd number of printed images distributed over the entire length should be arranged.

As printing blankets, in an advantageous embodiment, so-called metal printing blankets with an elastic and / or compressible layer located on a metallic carrier plate are used. In this case, it is advantageous that, due to the insertable metallic bent ends, these ends are in a narrow (eg, opening in the circumferential direction 5 mm at most), along the circumference of the transfer cylinder extending slot can be inserted. This variant of the blanket is for the above-mentioned assignments, particularly advantageous, however, in conjunction with two in the circumferential direction successively arranged blankets whose ends are arranged in two offset by 180 ° to each other over the usable length continuous channels.

In also advantageous embodiment are the blankets with a comparatively thick elastic / compressible effect Layer, z. B. at least 2 mm thick, and / or relatively compressible (softer) material. As a result, there are consequences of a vibration-related Fluctuation in the pressure between the cylinders reducible.

In principle, it is advantageous if the same pattern for the printing is provided for the printing forms and the blankets. Except for the combinations of D6b With D7c ) or d6c With D7b ), other combinations may be used to advantage.

D8 gives an overview of possible variants in the training of lengths and circumferences of the printing cylinder 303 ; 304 , in which case, however, particularly preferred variants are characterized by circling. The mentioned page numbers represent the page numbers that can be generated when fully occupied with printed pages of the standard format F1 (eg DIN A4), ie a production in the first operating situation (homogeneous assignment of the forme cylinder with printed images of the same format and the same orientation).

For the above dimensioning the bales of the forming and / or transfer cylinders are in an advantageous embodiment 303 ; 304 as a cylindrical body made of several layers of plastic, z. B. CFK, or cascaded constructed of several individually manufactured plastic tubes, z. As CFRP pipes that are glued or potted together. In this case, the base body may be formed exclusively of plastic, but in another embodiment also have a metallic layer, but the plastic layers at least significantly, z. B. at least halfway to contribute to the load as a load-bearing elements.

As mentioned above, in one embodiment several blankets and / or several printing plates next to each other (possibly also stacked) or on the circumference one behind the other on the corresponding cylinder 303 ; 304 arranged.

The Printing plates can be advantageous -. B. on the leading and / or trailing end - stiffened with strips, what advantages for transport and attachment on the Cylinder holds.

Rolling of the inking and / or dampening unit - in particular z. B. an above-mentioned chrome roller 329 and or one or more of the above applicator rollers - may be formed in the manner of impression roller, wherein z. B. the jacket tube is clamped against a continuous central shaft and / or supported. The same applies to the form and / or transfer cylinder in a special training, z. B. additionally in the plastic training.

advantages also result in an embodiment, wherein the Form and / or transfer cylinder of the printing works a Cooling - z. B. liquid cooling - have. The same can be used instead or in addition to their storage be provided. For such cooling can a cooling circuit with separate temperature control provided be.

In Another advantageous embodiment are one or more the cylinder of the inking and / or dampening unit is crowned, d. H. they have one in their middle (eg at least 0.5 mm) larger diameter than in their peripheral areas on to compensate for the deflection.

Cooling tower:

After cooling and drying, the web B (or two parallel webs B1, B2) exits the dryer 500 out and z. B. via guide elements 501 the cooling device 600 fed. The guiding devices 501 In this case, they can preferably be designed as guide elements with air outlet openings for forming an air cushion for contactless web guidance. In contrast to turning bars whose longitudinal axis is perpendicular to the direction of the incoming web B.

superstructure 700

After printing and any subsequent painting, drying and / or cooling in the cooling unit 600 the train B is running; B 'for further processing in the superstructure 700 , In the superstructure, the printed web B or the printed webs B are cut to the formats and the width processing corresponding partial webs, placed in the required alignment and / or the desired location, and aligned in this way and "sorted" the further processing in one or several folders 800 fed.

at Here present great web width, it is of particular Advantage, multiple products (identical, similar end products or sections of the same end product and / or completely to produce different products) at the same time.

In a simplest embodiment, this can be achieved by a folder 800 (with, for example, a folding unit) with only one exit, but a later separation of the products lying one behind the other. This is z. B. thereby realized that the two (part) products forming strands laterally slightly offset in the folder 800 come in and therefore come laterally from the display laterally offset from each other. When using folding hoppers in the superstructure 700 , For example, two formers with their funnel tip in a projected in the horizontal direction of transport of the incoming web (longitudinal direction) are relatively movable. When using only turning bars, the impact areas of the partial webs on the turning bars for the different products to be assigned web strands can be chosen so different that the alignment of the partial webs of one product and those of the other product are laterally slightly offset from one another.

In another embodiment, a folder 800 (With, for example, a folding unit, eg a cylinder group of transfer and jaw cylinders) several, z. B. two or three outputs (eg. U2 ), on which the different products are designed.

In a more variable version, a folder can be used 800 with a plurality of cylinder groups (with, for example, two or three folders, eg cylinder groups), each having one output or having a plurality of outputs on which the different products are designed.

In addition, in coordination with the possibilities of the folder / folders 800 the superstructure 700 set up or equip.

A folding former having superstructure 700 can be equipped with n funnels (n> = 0!), which are fixed and / or slidable in the longitudinal and / or transverse direction. In the case of n> = 2 funnels, it is basically possible to separate the products lying inside one another in the shingled stream (longitudinally offset funnels, see above).

In particular in the present case of printing units with printing cylinder cylinders of at least twice the circumference (ie at least four horizontal or vertical standard pages, eg DIN A4, one after the other in the circumferential direction), products with upright and / or horizontal sides can be processed very flexibly. In this context, it is advantageous for the flexible further processing, one or more variable size folders 800 (see below) and / or several folders at the same time 800 provide with different section lengths. A combination thereof and / or optionally an additional cutter can allow for special flexibility.

For the different applications with the corresponding folders 800 is preferably an optimized superstructure 700 advantageous. For example, in one embodiment, a folder is used 800 with in the strand path upstream folding hopper for the production of a product to be produced in cross-rupture with standing print pages (eg Broadsheetanordnung) on the forme cylinder (in the manner of a newspaper with longitudinal and transverse fold) in conjunction with a second folder 800 For pages on the form cylinder with trim for finished products in a tabloid, book or phone book format advantageous.

Also is a combined production of commercial products and / or phonebook products and / or Books side by side and / or one after the other on the same Machine advantageous in terms of economy. At simultaneity in the case of smaller product page numbers, there is no production be accepted with only part-wide lanes B.

Several or all sections of a final product or even different Products can be produced in one machine run.

Advantageous in connection with several sections or products to be produced at the same time is in the case of a superstructure formed with formers 700 the arrangement of at least two formers.

In the superstructure for online production - individually or in combination - further possibilities of inline processing such as punching tools and / or perforating and / or trimming and / or longitudinal or Querleimvorrich tions and / or means for a transverse section

The superstructure 700 in each case comprises a longitudinal cutting device 701 , by which the web B can be cut in one and / or two printing side width web strands bx. With a standard printing unit arranged on eight DIN A4 pages arranged side by side 300 are preferably at least seven blade units 705 , in a x (x = 6, 8, 10 or 12) juxtaposed DIN A4 pages designed printing unit 300 a number of at least x - 1 blade units are provided side by side across the web direction. Some, but advantageously all of the web B in web strands bx cutting blade units 705 are preferably arranged adjustable in the direction transverse to the web B. The knife units 705 are z. B. each individually driven rotationally and / or individually on / off. Preferably, the blade unit 705 designed to be axially movable on a frame-fixed traverse. The axial alignment can be done on manually adjusted techniques (release and displacement, manually driven spindle (s), etc.) or in an advantageous embodiment by drives (eg motorized by spindles). The latter is particularly advantageous if the axial positioning or at least presetting is carried out automatically by the machine control system on the basis of the width of the web B intended for printing and the cut lines to be made product-specifically or by a control panel.

The superstructure 700 Functionally and / or structurally, a Bahnkanten- or Bahnmittenregeleinrichtung with z. B. rotating frame and sensors, a silicone work with two consecutively in contact with the web B; B 'bring, each individually driven motor-driven applicator rollers, possibly a scanning device for measuring the color density and possibly a perforating (only indicated by dashed lines) associated and in particular the longitudinal cutting device 701 be upstream. Another advantage is the arrangement of scanning heads for color register control on both sides of the web B.

In an embodiment of the superstructure, not shown 700 (Funnel superstructure) the resulting web strands bx are all guided over the edges of formers. So that the web strands bx can be displaced laterally in their flight, depending on the product requirement, one or more turning decks are provided with pairs of rotating turning bars for displacing a number of part webs in front of the hopper unit with one or more formers. The guided over the / the former web strands bx are then - folded or cut at the longitudinal fold - as a strand bundle the folder 800 fed.

In another version of the superstructure 700 ("Magazinoberbau", eg U1 ), the resulting web strands bx are not passed through the former, but as a page-wide web strands bx on a turning plant 702 led, which -. B. side by side to the inlet direction - at least a number of turning bars 712 which corresponds to the number x of printed pages (eg lying or upright DIN A4 format) side by side on the maximum width of web B ( U1 ).

After deflecting the web strands bx by - projected into the horizontal - 90 ° pass through the web strands bx a register with at least x - 1 register rollers before the summarized web strands to one or more common strands together and one or more downstream folders 800 ( 800.1 ; 800.2 ).

In U1 is such a superstructure 700 exemplary with a turning work 702 for a printed with twelve printed pages side by side web B. In U2 is an example of a superstructure 700 represented, which for z. B. two webs B of two printing lines a turning plant 702 with a total of 16 or two turrets 702 with each exemplary x = 8 turning bars 712 having.

Preferably, several, in particular all of the turning bars of the turning plant 702 Transversely to the incoming web strand bx movable and / or formed with a length which is projected to the width of the incoming web strand longer (in particular at least 1.5 times) as a printed page of the standard format (eg DIN A4) in the transverse direction. In this way, web strands bx can be deflected with printing width larger than the standard format.

U2 shows an example of the leadership of the web strands bx together in a folder 800 , As in U3 However, the web strands bx can also be shown in parallel in two folders 800.1 ; 800.2 be guided. In this case, in the presence of a plurality of starting webs B, web strands bx of one web B can be assigned to the web of the web strands bx of the other initial web B. Different product strengths can be realized simultaneously. E6 shows an embodiment wherein from a starting web B by means of x turning bars the x web strands on two folders 800.1 ; 800.2 be split. With such a wide printing machine or web B, two identical products or two different partial products, each in a folding apparatus, can be simultaneously used for each revolution 800.1 ; 800.2 produce. This can be beneficial in terms of folding with increasing product strength (difficulty, accuracy, etc.). Likewise, as shown here two products of different page numbers can be produced simultaneously by -. B. starting from the web center of the starting web B - web strands bx variable the strand for one or the other former 800.1 ; 800.2 can be added.

In another advantageous embodiment, the two folders 800.1 ; 800.2 be formed differently from each other. So can the one folding machine 800.1 a Punkturfalzapparat 800.1 and the other a jaw folder 800.2 and / or the one folding apparatus 800.1 formed with respect to a fixed-format processing capability for a first section length and the other folding apparatus 800.2 be formed for a different second section length thereof (see, by way of example, the two folders 800.1 ; 800.2 in U4 with different distances between the holding tools of the transport cylinder 801 , ie different section lengths) and / or the one folding apparatus 800.1 with regard to a fixed-format processing possibility z. B. the standard product for a first section length and the other folder 800.2 as a folder 800.2 be formed with variable section length (ie, for example, with acceleration section) and / or the one folding apparatus 800.1 without and the other folder 800.2 be formed with means for forming a second longitudinal or transverse fold.

In a third version of the superstructure 700 may be advantageous from the first version ("hopper superstructure", with formers) and the second version ("magazine superstructure", without former) mixed execution. This is in addition to the turning plant 702 a funnel unit 703 with at least one former 708 intended. This former 708 may be provided in the railway one or more turning decks. With the mixed version, it is possible in an operating situation only single-sided web strands bx on the turning plant 702 a folder 800 supply, or in another operating situation one and / or two-sided web strands bx exclusively via the former 708 lead and longitudinally fed fed to a folder, or in the third operating situation Einseitenbreite web strands bx on the turning plant 702 and one- and / or two-sided web strands on the former 708 respectively. It is thereby possible to simultaneously produce two different products (eg a newspaper-like longitudinally folded product with printed pages of a first format in a broadsheet arrangement and a tabloid or book-like product of a second format) in two downstream folding machines provided for this purpose. In the latter case, the two web strands to be processed differently can originate from two different webs B of different printing unit lines. In a special embodiment, however, the two different formats can be arranged side by side on longitudinal sections of a same forme cylinder or side by side as print images on a same web B. For example, printed images of a stationary newspaper or magazine format could be arranged on the longitudinal section of a same forme cylinder, while on another longitudinal section, printed images of another stationary newspaper / magazine format or horizontal printed pages of a tabloid format are arranged. Through the first longitudinal section -. B. in vertical arrangement - printed web strands bx are, for example - at least partially - cut in two-sided web strands bx, folded longitudinally, cut in a folder to sections with a length corresponding to a standing pressure side, folded transversely and delivered to the display, while, for example the second longitudinal section - z. B. in horizontal arrangement - printed web strands bx are cut, for example, in einseitenbreite web strands bx, passed over the turning plant, cut in a folder to sections with a length corresponding to two lying print pages and transverse folded.

For the examples with two folders 800.1 ; 800.2 may, depending on the requirements of the delivery requirements a back-to-back arrangement (as in E5 ) or alignment in the same direction. In the latter, it may again be advantageous to offset the two folders in height to each other easily or a trained as a double folder folding unit 800 to use.

In a particular embodiment, the folder is 800 or at least one of the folders 800.1 ; 800.2 designed as a folder with variable section length. This points - as in F1 shown schematically - a transport cylinder upstream shear device 811 and an acceleration section for the cut product sections 808 (Signatures) - z. B. by means of a tape system - on. The equidistant distances of holding tools 802 on the transport cylinder correspond to at least the longest to be printed in the direction of web travel printed image. The transport cylinder 801 including tape system is designed so that it can be operated with a relation to the uncut strand higher conveyor or peripheral speed, while z. B. the upstream aggregates 300 operated essentially with the not yet transversely cut strand promotional speed / peripheral speed. Depending on the still uncut Strand set relative peripheral speed of the cross cutter 811 and cylinder rotation of the transfer cylinder 801 longer or shorter product sections are cut off, accelerated and removed from the holding tools 802 of the transport cylinder 801 added. This variable folder 800 is thus suitable for processing in two mutually different operating situation different arranged on the form cylinder printing side lengths. These may be, for example, printed page sections of the same format (eg DIN A4 format) lying in an operating situation and in another operating situation, or in a first operating situation printed page sections having a length of a first integer divider (eg six). of the forme cylinder circumference, and in another operating situation, pressure side sections having a length of a second, different from the first, integer divisor (eg, eight) of the forme cylinder circumference.

Below are schematically advantageous embodiments with web track guide for the execution of the superstructure 700 in combination with the folder 800 or folders 800 shown:
Ü7 shows a so-called magazine superstructure with a number x, z. B. 6, web strands bx, which are longitudinally cut through x - 1 knife and guided over x turning bars and one or more here not visible folding apparatus (s) 800 be supplied. The / the folder (s) is / are here z. B. oriented so that the axis of rotation of the transfer cylinder perpendicular to the axis of rotation of the upstream printing cylinder or projected into the horizontal direction of transport in the folder 800 transverse to the machine alignment M ("machine axis"). The web strands bx have in their width z. For example, in each case only one pressure side - in particular a lying pressure side (eg DINA4). For several folders arranged underneath ("FA") 800 the partial web bx can be split into two strands and simultaneously two folders 800 (or two groups of Falzzylinernn a Doppelfalzapparates) are supplied.

Ü8 shows a so-called funnel superstructure, but with the / the former 708 has a projected into the horizontal direction of curvature, which is perpendicular to the machine alignment M. A number x, z. B. 6 or in cross-break production z. B. 3, web strands bx, which are cut longitudinally by x - 1 knife over x turning bars on one another, over a (or possibly divided over several) former 708 guided, and one or more folding apparatus (s) 800 fed. The / the folder (s) is / are here z. B. oriented so that the axis of rotation of the transfer cylinder parallel to the axis of rotation of the upstream printing cylinder or projected into the horizontal direction of transport in the folder 800 parallel to the machine alignment M ("machine axis"). The web strands bx have in front of the turning bars in their width z. B. two printed pages - z. B. two horizontal pressure side (eg DINA4) on. In a broadsheet or cross-hatch production, the two-side wide web strands bx are above the former 708 longitudinally folded and for the cross-cutting and cross-folding the folder 800 or multiple folders 800 fed. In tabloid production (eg printed pages lying on the forme cylinder), the web strands bx can be arranged between turning bars and former 708 cut into one-side wide web strip and placed on each other by the former. For several folders arranged underneath ("FA") 800 the partial web bx can be split into two strands and simultaneously two folders 800 (or two groups of Falzzylindern a Doppelfalzapparates) are supplied.

UE9 shows the simultaneous production of two different products or product formats by means of a funnel superstructure: Here, the web B is in a number y web strands by with a first web width and a number of z web strands bz with a different from the first second web width (possibly according to the respective Print image widths) cut. The web strands by; bz different widths are now combined into strands and different folders 800.1 ; 800.2 fed. For example, the wider web strands by are above the former 708 longitudinally folded and further processed into a cross-break product (eg in the manner of a newspaper), while z. B. Einseitenbreite web strands on the other former 708 superposed and further processed in the second folder to a tabloid product. In UE9 For example, possible orientations of horizontal (tabloid) printed pages and upright (broadsheet) printed pages are indicated. In UE9 are the casserole directions of the two-sided formers 708.1 ; 708.2 as well as the transport directions in the folders 800.1 ; 800.2 formed parallel to each other. UE10 shows an arrangement according to UE9 , However, where the direction of curvature of the two-sided formers 708.1 ; 708.2 as well as the transport directions in the folders 800.1 ; 800.2 are formed antiparallel to each other. The latter is advantageous with respect to a backup function, since without much effort a same product with a same animation of the cylinder on one or the other folder 800.1 ; 80.2 can be produced.

UE 11 shows an embodiment above examples, but with two arranged on a same machine side folding 800.1 ; 800.2 - In particular, each with upstream former 708 ,

UE12 shows an advantageous embodiment, wherein a projected into the horizontal direction baking direction on the / the former 708 runs parallel to the machine alignment and / or perpendicular to rotation axes of the printing cylinder. The / the folder (s) is / are here z. B. oriented so that the axis of rotation of the transfer cylinder perpendicular to the axis of rotation of the upstream printing cylinder or projected into the horizontal direction of transport in the folder 800 transverse to the machine alignment M ("machine axis"). In this example, an operating situation is again shown, in which, for example, printed pages of different width / orientation are printed on the web B, and these are printed in differently wide web strands by; bz cut, and at the same time to two different products (intermediates) in two folders 800.1 ; 800.2 be further processed. The two folders 800.1 ; 800.2 can be on the same plane, verikal offset to each other, or as a folder 800 be formed with two folding cylinder groups and two displays.

UE13 shows a schematic front view of a magazine superstructure (without former) with a downstream folder 800 - comparable to a version according to Ü7 , Ü14 in contrast, a funnel superstructure with a former between turning bars and the folder 800 ,

UE15 shows a schematic front view of a magazine superstructure (without former) with two downstream folders 800 , Schematically, by means of only an exemplary number of web strands bx; by; bz a division into two folders 800.1 ; 800.2 shown. To this end Ü16 schematically the case for a hopper superstructure with two formers 708 and two folders 800.1 ; 800.2 , wherein two strand bundles of web cords guided over the former, and fed simultaneously two folders. As indicated by the "crossing", one, several or all web strands can be transferred from one bundle to the other (for example in order to be able to realize correspondingly different section or product strengths). On individual strands, a stapler may be provided to remove a part of the layers to later product as a stapled booklet. The here offset to each other arranged folders 800.1 ; 800.2 can also be arranged at the same height next to each other.

With only one folder 800 has this, or in two folders at least one of the folders 800.1 ; 800.2 preferably in addition to the first transverse folding device (eg folding blade with folding jaw cylinder) downstream of a means for forming a second transverse fold 803 and / or a means for forming a longitudinal fold 804 on. This is exemplary in E5 However, each is on one of two folders 800.1 ; 800.2 or the some folder 800 of the remaining examples.

P1 shows production possibilities with a printing line, its printing cylinder 303 ; 304 has a width of 12 and a circumference of four standing DIN A4 pages (dimensions see eg above) and two folders 800.1 ("Fold 1"); 800.2 ("Fold 2") or a folder with two folding cylinder groups and two displays are arranged downstream:
In the illustration, a raster for occupancy with standing DIN A4 printed images is at the top in the middle, obliquely hatched an exemplary representation of a tabloid page, and indicated by cross-hatching an exemplary representation of a stationary page in a DIN A2 or corresponding newspaper format.

The two under the indicated folders 800.1 ("Fold 1") and 800.2 ("Fold 2") shown tables indicate advantageous productions. From a web B are each a product example of a line of the first table by the first folding apparatus 800.1 and at the same time a product example from the same line of the second table with the second folding apparatus 800.2 produced. It is advantageous, for example, for a standard production with homogeneous form cylinder occupancy on the first folder a partial product of 48 A4 pages and the second folder 800.2 also a partial product of 48 A4 pages are designed. These two subproducts can then represent two identical products, with different print image occupancy, two parts of an overall product or two different products, given a print image occupancy repeated on the form cylinder in half. With an equally interesting production variant, it is possible to produce three sub-products having the same page number, if for example at one folder two unsollected 32-page partial products (from four double-sided or 8 single-pagestrands), and at the other folder an unsaved 32-page partial product ( from two double-sided or 4 single-sided strings) is generated and designed. If all the strands of the superstructure (here two strands of paper are denoted as strands of two DIN A4 pages) are fed onto a folder, a product with 96 DIN A4 pages can be produced in collective production (marked with >> in Tab.).

Particular advantages also result in production with inhomogeneous cylinder occupancy, ie with an occupancy of the forme cylinder 304 side by side with different print image formats -. B. standing A4 and lying tabloid in A3, or standing A4 with standing newspaper format in A2:
So, for example, in addition to the above production on the first folder 800.1 at the same time a production of products in Tabloidformat T possible (in Tab exemplarily for two cases marked with *.) For example, on one folding machine one A4 product with 2 × 32 sides or 64 sides, and at the same time on the other folding apparatus a Tabloidprodukt with 16 sides (or 2 × 8 sides), whereby the strands generated from the same web B divide as indicated in each case in column 1. The assignment with the different print images on the forme cylinder takes place in each case according to the screening in the required strands P2a ) is an example of the above inhomogeneous assignment (2 × 32 or 64 A4, 2 × 8 or 16 pages tabloid) given as an example. The remaining variants for inhomogeneous A4 / tabloid production should be applied accordingly.

In P2b ) is an example of the simultaneous production of an A4 (or alternatively tabloid) and - z. B. as an advertisement or small newspaper - a newspaper-like product in broadsheet arrangement of the printed image. For example, in this example, four of the two-A4 widths "strands" are printed in the manner of newspaper pages Z. These four "strands" do not have to be cut in four, but can be cut into only two web strands, and the two two-page wide web strands are passed over each other via a funnel before entering the folder 800.2 enter.

In an in P2c ) variant indicated by way of example, in addition to the standard A4 product A (a multiple of two in the circumferential direction), for example, another format deviating from DIN A4 format (eg special format S, for example with a number of printing pages corresponding to a multiple of three in the circumferential direction). In the widthwise direction of the cylinder, but the print images do not have to reach all the way to the end of the effective bale, this variant of production is particularly useful in conjunction with a variable length folder, for example, the first folder is more rigid Punkturfalzapparat, and the second folder, for example, as a variable-size folder 800.2 educated. The latter can be operated with the corresponding requirement, depending on the mode of operation and occupancy (homogeneous / inhomogeneous) of the machine.

In P3 the conditions for the production possibilities are accordingly above P1 , but for a printing unit line, the printing cylinder 303 ; 304 has a width of 12 and a circumference of six standing DIN A4 pages (dimensions see eg above) and two folders 800.1 ("Fold 1"); 800.2 ("Fold 2") or a folder with two folding cylinder groups and two displays are arranged downstream. Again, in the illustration at the top in the middle of a raster for the occupancy with standing DIN A4 printed images, obliquely hatched an exemplary representation of a tabloid page, and indicated by cross-hatching an exemplary representation of a stationary page in a DIN A2 or corresponding newspaper format.

In the P2 set forth principles are directly transferred to this case, in the circumferential direction correspondingly more of the pages shown (A4, T, Z, S) are to be arranged. In one too 2c comparable operating situation, can here as a special format z. B., for example, in the circumferential direction a multiple of three corresponding number of printed pages - here in the circumferential direction z. B. four or eight printed pages with corresponding side lengths in the circumferential direction - be provided.

In the special embodiment of a supply of two webs B1; B2 side by side through the printing units, can in the vorgenanten Examples of a longitudinal section between two web strands bx; by; bz omitted, since here the joint of the two tracks B1, B2 runs.
