The DE 25 28 008 A1 shows a printing machine for a direct printing method with form cylinders, which can be equipped in the axial direction with six and in the circumferential direction with two printing plates, and counterpressure cylinders, which are assignable in the axial direction three and in the circumferential direction with a pressure felt. Both the pressure plates arranged next to one another and the pressure felts arranged next to one another are offset relative to each other in the circumferential direction.

The DE 24 22 696 C2 shows a six-plate wide satellite printing unit with offset printing units (nine or ten cylinders), wherein the two middle of six arranged in the axial direction of adjacent printing plates with respect to the outer circumferentially offset on the forme cylinder are arranged.

By the DE 41 28 797 A1 is a triple-width web-fed rotary printing press with two on two different, superimposed planes arranged formers known.

From the US 4,671,501 A a Falzaufbau is known, wherein two formers are arranged one above the other, the webs after passing through overrun rollers in front of a third funnel cut longitudinally, the sub-webs are rotated over a third funnel by 90 ° and then combined into two strands fed to the two superposed funnels ,

By the EP 10 72 551 A2 is a Falzaufbau with two vertically offset groups of three formers known.

In the WO 97/17200 A2 a folding structure is known, according to which cut, transversely offset to each other part webs are fed to different formers. The horizontally juxtaposed former are z. T. vertically offset from each other.

By the EP 12 38 935 A2 is disclosed a longitudinal cutting device for variable cutting widths with movable in the axial direction upper blades and a lower blade shaft with a beyond the number of outer blade grooves.

The DE 42 04 254 A1 discloses a folding structure of a four newspaper pages wide printing press, wherein in a lower hopper level two slidable transverse to the direction of web travel formers and in a plane above a single stationary formers are arranged. In one mode of operation, a four-page newspaper is produced side by side over the two lower formers, and in another mode six pages of a directory side by side with the three funnels, the two lower funnels having moved apart in the latter case.

The EP 10 72 551 A2 shows a former arrangement with two groups of three formers, wherein the formers of a group lie in a plane and overlap in at least in the horizontal direction in its vertical extent.

From the DE 196 28 647 A1 It is known to print a web with panoramic print pages, ie the pressure on two pages of newspapers without interruption.

The DE 100 16 409 A1 disclosed in connection with double-wide printing units a transfer cylinder having two blankets side by side. In addition to single and double-width cylinders triple-wide cylinders are also called.

The invention has for its object to provide a web-fed rotary printing press with ienem printing tower.

The object is achieved by the features of claim 1.

The advantages that can be achieved with the invention are, in particular, that a cost-effective and highly productive design of a web-fed rotary printing press for the secure production of different product formats is made possible.

This is especially for a six-page wide machine z. B. by two juxtaposed, three-page wide blankets allows. The different format tracks, z. B. webs are each driven centrally to the transfer cylinder, so that the impact of the two blankets comes to rest on the middle double side in the region of the longitudinal fold in the non-printed area.

It is particularly advantageous if one or more devices of the guide and / or processing elements acting together with the web are variably adjustable to the different web width. These are, for example, pressure rollers in the intake train, catch rollers of a safety gear, blades of a longitudinal cutting device, pressure rollers of a train group and / or juxtaposed folding hopper of a folder structure. The web is advantageously symmetrical to the printing press center axis - ie, for example, centered to the cylinder width - passed through the machine. In a preferred development of an odd number of guiding and / or processing elements a mediator is arranged in said plane of symmetry. This can then in the transverse direction to Transport direction to be fixed, while the outer guide and / or processing elements to be movable transversely to the transport direction and thus should be made adjustable to the web width.

In addition, the advantages of triple-width printing presses are that production reliability is considerably increased when compared to a double-width press with the same target thickness of a product to be achieved. While maintaining the number of printing units but also the output of the printing press, or each printing unit can be increased by 50%. The number of reelstands (investment), the frequency of reel changes (production safety) and the set-up time when webs are drawn in (cycle times) can be reduced compared to a double-width press for the same product thickness.

In an advantageous embodiment, the printing units are designed as nine-cylinder satellite printing units, which on the one hand has a high precision in the color register and on the other hand a low-vibration construction result. The training as a satellite printing unit is also advantageous because when the requirement for printing different web widths in rubber-to-rubber printing unit for at least one web width vorlägen direct contact zones without paper web. This would, as is well known, lead to greatly changed promotional behavior, which is currently the case. significant registry deviations and wrinkles can result.

Vibrations are also reduced by the advantageous arrangement, design and mounting of lifts on the cylinders. On the one hand, openings on the lateral surfaces in the circumferential direction are minimized. Furthermore, at least on the transfer cylinder, the openings may be arranged alternately offset in the circumferential direction, that acts at least on a section length always a closed lateral surface with the forming or satellite cylinder together.

Particularly advantageous is the symmetrical to the width of the transfer cylinder assignment with only two three-page wide elevators. Thus, in contrast to previously usual two two-sided printing blankets at different web widths, a printing without previous blanket changes done.

The mechanically independent of the cylinder pairs drive the (or the) satellite cylinder has particular advantages in terms of the possibility of variable operation. For example, during production, a setup, z. As a flying printing form change or washing done. Conversely, a web can be retracted while other cylinders or pairs of cylinders are standing or undergoing a set-up program. Also, it is advantageous to operate in the presence of rubber blankets with positive or negative promotional properties, the satellite cylinder with a different surface speed of the other cylinders.

In an advantageous embodiment, a superstructure of the printing press has at least one longitudinal cutting device with at least five knives spaced apart from one another transversely to the direction of travel of the paper.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

The printing machine is as already mentioned above for the production of various product formats, i. H. the printing of webs 03 of different widths designed. This does not mean a different width due to partial-width webs, as would be the case with "half", "third", "two-thirds" webs of the same basic web. With the different web width, a different product format is associated with the same number of possible pages.

Forming and transfer cylinder 16; 17 show in a particularly advantageous embodiment, the occupancy shown in Figure 3 with the elevators 19; 21 on. In Fig. 4, this is a particularly advantageous arrangement of channels 27; 36; 37 for attachment of the elevators 19; 21 shown. On the forme cylinder 16 two over the effective length of the forme cylinder 16 each continuous, spaced by 180 ° from each other in the circumferential direction channels 27 and channel openings 28 (openings 28) and the transfer cylinder 17 two in each case over half the effective length, by 180 ° to each other in the circumferential direction offset channels 36; 37 or channel openings 38; 39 (openings 38, 39). The channels 27; 36; 37 are shown in Fig. 4 only slot-shaped for insertion of elevator ends, but can inside, as explained in more detail below, open to receive a corresponding clamping and / or clamping device.

In Fig. 4 is a form and a transfer cylinder 16; 17 having printing unit 13 for printing a variable web width shown schematically together with a folding structure 11 described in more detail below and two web widths. In a first operating mode, a web 03.1 having a first width b1 for printing with a first print page format F1 and in a second operating mode a web 03.2 having a second width b2 for printing with a smaller, second print page size F2 is printable, and wherein the transfer cylinder 17th has a width in the axial direction of at least six newspaper page widths of the larger printed page format F1, and on its circumference in the axial direction side by side two blankets each having a width in the axial direction of three newspaper page widths at least the smaller format F2, z. B. page size F2 - but better of the larger format F1, z. B. print page formats F1 - have.

A page number of newspaper pages viewed in the axial direction is z. B. in the first mode (newspaper printing, F1) and the second mode (newspaper printing, F2) is the same. It is preferably six pages of the corresponding format F1; F2.

The larger width b1 is suitable for printing six juxtaposed newspaper pages in the first format F1 and is z. B. at 1,800 to 2,500, advantageously at 1,900 to 2,400 mm, in particular at 1,900 to 2,200 mm. The smaller width b2 is suitable for printing six juxtaposed newspaper pages in the second format F2 and is z. B. at 1,750 to 2,100, advantageously at 1,750 to 2,050 mm, preferably between 1,850 mm and 1,950 mm, but where b1> b2. The possible widths for the newspaper printing are not to be applied to the two mentioned, but for any arbitrary intermediate widths or formats. Ie. In principle, therefore, all tracks 03 of different widths (or corresponding newspaper formats) can be varied, which z. B. from 1,750 mm to 2,400 mm, at least from 1,850 and 2,200 mm.

Also in Fig. 3 and 4, an imaginary printing machine center axis M is indicated. The two elevators 21 are arranged symmetrically to this printing press central axis M. The track 03.1; 03.2 passes through the printing units 13 regardless of the width b1; b2 symmetrical to this printing press center axis M.

In at least one of the modes of the form cylinder 16 of the printing unit 13 carries z. B. one in the axial direction over at least three newspaper page widths of the currently relevant format F1; F2 reaching printing form 19 "(see below) .This is then for example next to each other with printed images of three newspaper pages or one provided a total of three newspaper pages corresponding printed image, in particular exposed. Likewise, the funnel tip of a middle of three juxtaposed formers 41 is located; 42; 43 of the hopper assembly 11 in this printing press center axis M (see below).

5 schematically shows the situation for a wide web 03.1 (FIG. 5a) and a narrow web 03.2 (FIG. 5b), the main cutting lines S1 and S2 being shown for the two different product widths (web widths). The term "main cutting lines" is understood here to mean the longitudinal sections which guide the web 03 in alignment between two adjacent formers 41; 42; 43 separates, so that the resulting partial webs only on the adjacent formers 41; 42; 43 become feasible. The additions ".1" and ".2" (in S1.1; S2.1; S1.2; S2.2) express that in each case they are transverse to the transport direction and different from the first position second layer of the respective main section line S1; S2 corresponding to the two different formats F1; F2 of the product or widths b1; b2 of the tracks 03.1; 03.2 acts. The longitudinal sections along the main section lines S1 and S2 can be produced by means of the longitudinal cutting device 06 mentioned in connection with FIG. 1 or a comparable longitudinal cutting device, not shown in FIG. 1, before the funnel inlet. A particularly advantageous embodiment of a longitudinal cutting device (06; 65) suitable for this purpose is set out below.

Also shown in Figs. 5 to 10 are here with F41; F42; F43 designated folding planes which the symmetry planes of the respective former 41; 42; 43 represent and in which, if trained accordingly, the funnel tips. It can be seen that a distance A1 between the folding planes F41 and F42 and a distance A2 between the folding planes F42 and F43, depending on the width b1; b2 of the track 03.1; 03.2 and / or the current print page format F1; F2 and / or the type of assignment with printed images (symmetrical / asymmetrical) varies. Preferably, these varying distances A1; A2 by movement of the outer formers 41; 43 achieved, wherein the middle former 42 remains stationary. Secondary cutting lines S4; S5 (not shown in FIGS. 5 to 12), for example, in addition to the above-mentioned main section lines S1; S2 in the folding plane F41, the folding plane F42 and / or the folding plane F43 be provided, then in the case of the sidecut no longitudinally folded, but one cut on the back, loosely superimposed multi-layer product is formed (see tabloid production Fig. 13 to 16 and special format with Pflugpfalz Fig. 17 and 18).

With reference to FIGS. 6 to 10 are advantageous assignments and configurations of the elevators 19; 21, in particular the printing plates 19, for the wider and the narrower web 03.1; 03.2 set forth. The illustrated elevators 19; 21, however, do not correspond to a top view but a complete development of the respective cylinder 16; 17th

For all subsequent explanations to FIGS. 6 to 10, the transfer cylinder 17 is equipped in the axial direction next to one another with two three-page-wide elevators 21 of the larger format. In an advantageous embodiment, these two elevators 21 may each extend around the full circumference and may either be aligned with their ends (joints in the channel openings 38, 39) or be offset by 180 ° in the circumferential direction (see above). In another embodiment, two elevators 21 can be arranged one behind the other in the circumferential direction, in which case the ends of the two side by side arranged three-sided elevators 21 are aligned with each other. It is advantageous in any case if the two elevators 21 arranged axially next to each other together at least extend over the length of the transfer cylinder 17, which is required for printing the wider web 03.1.

In Fig. 6 and 7, a preferred variant for occupancy of the transfer cylinder 17 - namely two each extending over the full extent three-sided printing elevators 21 - shown by dashed lines. In Fig. 8, 9 and 10, the three-page wide version in axial Direction shown, the execution in the circumferential direction, however, left open and can be one of the above variants.

Fig. 6 shows the assignment of the forme cylinder 16 with printing plates 19; 19 'in the mode in which it has printed images of the larger printed page format F1. The web width corresponds to the larger width b1. Here, all (here twelve) 19 designed as a single printing forms 19 printing forms can be arranged. However, combinations of individual printing plates 19 and panoramic printing plates 19 '(illustrated by way of example at the bottom right in FIG. 6) can also rest. The latter have a width of several -. B. two or even three - individual printing on 19 and wear either a mehrdruckseitenbreites print image (panorama print page) or more each one or more pages wide print images of the first (larger) print page format F1. A distinction is made here between panorama print form 19 '(19 ") and panorama print image or print page: A panorama print form 19' (19") can have individual or panoramic print images in this sense. The distances A1 and A2 in FIG. 6 correspond in each case to twice the width b19 of a single printing form 19 or twice the printing page width bF1 of the larger format F1 or the width b19 'of a panorama printing form 19' or printing image of the larger format F1. The printing plates 19; 19 '; 19 "are preferably formed as planographic printing plates for offset printing.

In contrast to Fig. 6, Fig. 7 shows the layout of the forme cylinder 16 with printing forms 19 "in the mode in which it has printed images of the smaller printed page format F 2. The web width corresponds to the smaller width b 2 each symmetrical to the printing machine center axis M two panoramic printing plates 19 "arranged, each having a width of several -. B. two, in particular three - not shown, theoretically required individual printing forms of the smaller format F2 and either as in Fig. 7 more - here three - each impression-side printed images of the second (smaller) print page format F2 or as in Fig. 8, respectively one multi-page printed image and impression-wide print image wear. The forme cylinder 16 is equipped in FIG. 7 with double circumference (ie two newspaper pages on the circumference) with four, two on the circumference side by side and two consecutively, such, in each case three printed images of the smaller printed page format F2 side by side supporting printing forms 19 " Single circumference would be only two such printing plates 19 "side by side. In Fig. 8, the printing plates 19 "each have a multi-page printed image and an impression-side wide printed image, but mixed variants are possible but not shown here, and the distances A1 and A2 in Figs , Single-sided printing form, not shown, or twice the printing page width bF2 of the smaller format F2.

Preferably, the printing forms 19 "carrying the smaller printed page format F2 do not merely have the width of the three printed pages, but extend to the end of the effective lateral surface of the forme cylinder 16. The two adjacent printing forms 19" thus together have a width corresponding to the maximum or maximum width. the larger width b1 of the wider track 03.1. Thus, over the entire effective length L16 of the forme cylinder 16 a more uniform transport behavior is possible regardless of the web width just used and / or reduces the risk of dry running of the corresponding elevator 21 in the edge zones when using the narrower web 03.2. The printing plates 19 "then carry the printed images asymmetrically with respect to their width and are, for example, asymmetrically exposed during the production The non-printing edge region is 50 to 100 mm.

9 and 10 show the occupation of the forme cylinder 16 with three-sided printing forms 19 ", which are asymmetrically provided with printed images, two printed images (eg format or printed page format F4 and F5) lying on a printing form 19" do not have an integer ratio their width; the cutting lines S1.x; S2.x are z. B. not symmetrical to the printing press center axis M. The distances A1 and A2 are z. B. different from each other. At least in one of the three formers 41 to 43 (here at 42 and 43) falls the folding plane F41; F42; F43 (here F42; F43) does not coincide with the center of the associated partial web 03a; 03b; 03c (here 03b and 03c) together, so that the resulting longitudinally folded sub-strand has unequal leg lengths.

11 shows a web run of a production, wherein the longitudinally cut partial webs 03a; 03b; 03c; one or more webs 03 printed in a printing tower 01 or in several printing towers 01; 03 'straight ahead (without turning) accumulate on the three juxtaposed former 41 to 43, there folded longitudinally and finally fed to the folder 12. The form shown schematically in side view of Figure 11 formers 41; 42; 43 has a total usable leg length, which corresponds to at least one sixth of the width b1 of the wider (or widest) web 03.1 (b1 / 6). Also indicated here is a strand width, which results in production with the narrower width b2 to b2 / 6.

Fig. 12 shows a comparable to Fig. 11 representation, wherein in addition to the three formers 41 to 43, a further former 34 - in particular laterally to the other three - is arranged. About this is in so-called. "4-hopper production" at least one cut partial web 03a to 03c turned out of the straight line, passed over this fourth former 44 and finally fed to the folding apparatus 12 in addition to the other strands. The four formers 41 to 44 each have a total usable leg length, which corresponds to at least one sixth of the width b1 of the wider (or widest) web 03.1 (b1 / 6).

In an advantageous variant, the printing machine is in an operating mode for the printing of six juxtaposed standing printed pages of a newspaper format F1; F2 formed format F1; F2 (on a correspondingly wide web 03.1, 03.2) and in other operating mode for the printing of four juxtaposed lying printed pages operated as a tabloid format F3 format F3 operated or operable. For this purpose, in FIGS. 13 and 14 a first embodiment and in FIGS. 15 and 16 a second embodiment are given.

In anticipation of the set forth to Fig. 13 and 14, the fourth former 44 (as Zusatzfalztrichter 44) of FIG. 12 z. B. in a first embodiment of the o. G. Variant a greater maximum width in comparison to the formers 41 to 43, d. H. a usable maximum leg length, which is significantly more than one sixth of the width b1 of the wider (or widest) web 03.1 (b1 / 6) - in particular at least 120% of the sixth of the width b1 of the wider web 03.1 - corresponds. With this, optionally a production (format F3) shown in FIGS. 13 and 14 can optionally be run for a newspaper production (format F1; F2).

13, the form cylinder 16, in particular the six-page page width, is again provided with only two panoramic printing plates 19 ", which, however, carry printed images of a tabloid format F3 (and not a newspaper format.) The incoming web 03.3 here has another, of the first one The width of the print images lies with their subsequent product length (after transverse fold) in the axial direction of the forme cylinder 16 and correspond to a quarter of the width b3 of the web 03.3 (b3 / 4) (see FIG. The width of the product, after the transverse fold has not been shown, results essentially in one quarter of the circumference U _{FZ of} the forme cylinder (U _FZ / 4) .b width b3 is smaller, for example, than the two other widths b1; b2 and lies, for example at 1,600 to 1,800 mm, preferably between 1,700 mm and 1,750 mm, the printed web 03.3 in this case along a main section line S3 of the tabloid format (preferably coincides with the Printing machine central axis M together) cut longitudinally along the middle, both partial webs 03a; 03b are each turned over a turning bar 46 by 90 ° from the previous transport direction to a longitudinal side of the printing machine and out of alignment three formers 41 to 43 out, whereupon they either transverse to the printing machine center axis M via a correspondingly oriented formers 44 or - like shown - after another Diverting at a further turning bar 46 by 90 ° via the correspondingly oriented former 42 to the folding apparatus 12 are supplied. The former 42 again has a larger maximum width compared to the formers 41 to 43, ie a usable maximum side length which is significantly more than one sixth of the width b1 of the wider (or widest) web 03.1 (b1 / 6) - in particular at least 120% of the sixth of width b1 of the wider orbit 03.1 - corresponds. In the folder 12, the tabloid product is completed inter alia by cross-cutting. For the selective production of tabloid or newspaper products, the former 34 (tabloid format F3) or the group of formers 41 to 43 (newspaper format F1 and / or F2) is thus optionally used.

The conception of the asymmetrically exposed panoramic printing plates, in particular together with at least one of a plurality of transversely movable formers 41; 42; 43 is in addition to the six pages wide machine (six print images side by side) on other machines, especially four pages wide newspaper presses (four print images side by side), applicable. In this case, for example, for the six-side-width machine n = 3 printed images and for the four-side-wide machine n = 2 printed images in the axial direction next to each other on a printing forme 19 ", in particular asymmetrical, arranged An example is given in Fig. 33a and b, wherein 33a of the forme cylinder 16 is covered with printed images of the larger format F1, wherein the four printed images can be arranged only on eight individual printing forms 19, only on four panorama printing form 19 '(two adjacent and one behind the other) or combined (for example in FIG The printing plates 19, 19 'preferably cover the entire effective length L16 or the width b1 of the printable larger train 03.1. If the printing unit 13 is not double-circumference (two newspaper pages in the circumferential direction) but simply executed, then this applies equally to four single-printing forms 19 two panorama printing plates 19 'or mixed.

In the other mode of operation with a narrower web 03.2, the forme cylinder 16 now has printed images of the smaller format F2. Preferably, the printing plates 19 "are now again in the form of panoramic printing plates 19", but with two printed pages of the smaller format F 2, and nevertheless they again extend substantially over the range of the possible printing length of the wider web 03.1, d. H. they have the same width as panoramic printing plates 19 'of the larger format F1. As described above, the printing formations 19 "are, for example, again asymmetrically exposed, as in the above-mentioned arrangement with three funnels, a funnel construction is also advantageous, wherein a distance A1 of the folding planes F42, F43 can be changed in the above-mentioned manner.

As shown in FIG. 33, for example, two printing blankets 21 are arranged next to one another on the transfer cylinder 17, each having a width of two printed pages of a newspaper format F1; F2, in particular of the larger newspaper format F1. These can then each extend to the full extent and with their ends to each other again in alignment or be arranged by 180 alternately on the transfer cylinder.

It is explicitly pointed out that the following, to the printing machine shown in FIG. 34 considered both on its own, but also to a particular extent together with one or more of the features described so far, such. B. the three newspaper pages wide blankets21 and / or the three newspaper pages wide printing plates 19 and / or the format variability and / or the described adjustability of one or more of the guiding and / or processing elements 41; 42; 43; 52; 62; 66; and / or the satellite construction and / or arrangement of channel openings 28; 38; 39 and / or width of channel openings 28; 38; 39 and / or the special arrangement of formers 41; 42; 43; 44 and / or other features not mentioned in this list advantageous features. The same applies to the contents of Figs. 35 and 36.

Fig. 34 shows a printing machine, in particular in a three-width version for the printing of six juxtaposed newspaper pages, wherein each folding structure 11 (for example, two planes with three Falzrichtern side by side) on both sides printing towers 01; 01 a are associated with stacked printing units, in particular satellite printing units. An essentially in the same way equipped press section has, for example, on both sides of the folding structure 11, two printing towers 01; 01 a, wherein in an advantageous development of at least one of these printing towers 01 in addition to the eight pressure points of the satellite printing units 02 two more pressure points, z. B. in the form of a six-cylinder pressure unit 83 and two three-cylinder pressure units 83, respectively. If necessary, these two additional pressure points can also be printed on a printing tower 01 of a printing machine detached from the special printing press according to FIG. 34 in combination with one or more of the above-mentioned. Features be advantageous. In such an extended printing tower 01 a can then either two webs 03 each one-sided four-color and on the other side monochrome, or a web 03 on both sides four-color and a second web 03 are printed on both sides monochrome. The printing machine is here in contrast to Parterreausführungen (see Fig. 35, 36) designed multi-level in the sense that the printing towers or the respective lower printing units 02 and the roll changer 05 are not arranged on a same system level. The printing towers 01 are hereby arranged in a plane T above the plane G supporting the roll changer 05. The former are arranged for example on a so-called "table", in particular concrete table.

The printing machine of FIG. 34 here has three such printing press sections, wherein, as exemplified by *, webs 03 from remote printing towers 01 of the adjacent printing press section, but before the next folding structure 11 lying, can be transferred. Each one of four printing towers 01; 01 a and a folding structure 11 existing sections are z. B. assigned five reel changer 05. Depending on the requirements of the desired productions, turning towers with three, four or five turning devices 07 (turning decks) can be provided. Each folder assembly 11 is a folding apparatus 12 (here F1, F2, F3) arranged downstream. In addition, a selection of advantageous production possibilities and products are also listed in FIG. The description is explained on the basis of the gray-backed production for the illustrated web guide of line 3:

In the configuration according to line 3 on two folders (here F1 and F3) two products (2 x) with 84 pages (pages p) each of 7 webs (webs) are generated. This takes place here in broadsheet arrangement (ie stationary newspaper pages in the circumferential direction of the forme cylinder 16, and in double production, ie in operation without collecting (noncollect).) For example, two double-sided forme cylinders 16 can each have two same printing plates 19, 19 ', 19 "and thus a double output of products per unit time per strand are generated, or it can be alternately produced on the strand and two different products alternately discharged into two product streams." For example, on the first folding apparatus 12 from the left (F1) initially printed in 4/4 print from the right side, two in the printing tower left outside 1/4 and 4/1 printed webs and a 4/4 in the adjacent printing tower printed web.The product has 84 pages, from which 72 are colored in four colors (and the rest in monochrome) (84/72) For the product produced on the other folder (F3) here is the sel The remaining nine lines of the table can be read in the same way. B. in line 6 on two folders (F1 and F3) each of 6 webs (w) a 72 pages (p.) Strong, 60 four-color pages exhibiting product and on a folder (here F2) a 24-sided product,

In an advantageous embodiment, the offset printing units 13 are at least one of the printing units 02 of a printing tower 11 (eg, however, of all printing units 02, 83 of a printing tower, but advantageously of all printing units 02, 83 of an entire printing press section, but especially of all printing units 02, 83 of the printing machine ) in the embodiment described above with three-page-wide printing plates 19 "and / or three-page-wide elevators 21 fitted or fitted formed.

The folding structures 11 have z. B. at least one funnel plane, but advantageously two stacked funnel planes with the three juxtaposed formers 41 to 43 (eg., From Fig. 4 to 16). One or more of these folding structures 11 may advantageously additionally have a lateral additional funnel 44, as shown in FIGS. 12 to 14 (or optionally an additional funnel plane).

Fig. 35 shows a printing machine in Parterrebauweise, d. H. Roll changer 05 and printing towers 01; 01a are at substantially the same level E, z. B. a ground floor level E arranged. This may provide advantages in terms of construction costs (no basement or lower height of a building 86 housing the towers 01, 01a, eg a hall 86). In an au outside the printing towers 01; 01 a and / or folding structure 11 lying area then the building 86 can be made significantly lower (indicated in Fig. 35).

As can be seen in the plan view (lower part of the figure), an additional folding hopper 44 can be arranged laterally to the group of the three formers in the folding structure 11 shown. This may be the case for one of the two or for both funnel planes drawn out, for example, if each of these again three formers 41; 42; 43 side by side. This additional hopper may have the same width as the other three formers, but as shown in FIG. 13 also have a greater width. There are seven possible funnels here (two times three plus additional funnels) Product strands (eg so-called "books") and - in the case of a larger funnel width of the additional funnel-optionally on the additional funnel a product of greater width In an embodiment without the laterally arranged addition funnel 44, the two funnel planes can also be arranged in the position shown in FIG. 16 may be implemented (one level three funnels, the other level two wider funnels) Optionally may be an embodiment wherein two "normal" hopper levels are provided with three juxtaposed formers as shown in Fig. 32, and additionally two additional formers 44 in an overlying level (indicated by dashed lines) in the manner of the two upper formers 44 of FIG. 16 are arranged above.

One or more of the printing towers 01, as referred to here as 01 a, additional pressure units 83 have.

In one embodiment of a printing press according to FIG. 36, the web feed from the roll changer 05 takes place from the longitudinal side of the machine, ie at a 90 ° angle to the printing press center plane M. Preferably, the printing press is also executed in parterre construction, ie roll changer 05 and printing towers 01; 01 a are arranged on substantially the same plane. The or the roll changer 05 is or stand laterally next to the machine, wherein the axis of rotation of the material or paper rolls runs substantially parallel to the printing machine center axis M. After unwinding across the machine, the web now runs at the height of the machine alignment on a deflecting element 84, z. B. a guide element 84 in the manner of a turning bar 84, on, so that the direction of movement thereafter lies in the printing machine center plane M. The guide element 84 has a length which corresponds in projection to the incoming web at least its maximum width. It is preferably inclined by 45 ° to the running direction of the incoming web and to the machine center plane M. In the present case, it has a length whose projection on the incoming web corresponds to at least six adjacent newspaper pages. In the case of the 90 ° offset of the roll changer 05, the usable length of the turning bar 84 corresponds at least 1.4 times the maximum web width to be processed in the printing press, ie in this case at least 1.4 times the width of a six-page wide web or in this case at least 8.5 newspaper page widths. Between two towers 01 two crossed turning bars can be provided, which then allow the deflection in one direction and in the other direction. The two crossed turner bars 84 can then either be acted on by a roll changer 05 with this web, or as shown, are acted upon by two in the same flight roll changer 05 simultaneously.

With regard to the safe web guide, the web tension adjusting feed mechanism may optionally be provided before the turning bar 84, but advantageously between turning bar 84 and entry into the printing tower 01.

The lateral arrangement of the roll changer 05 can again be considered on its own, but also develop particular advantage in conjunction with one or more advantageous features.
