After printing and drying, preferably by means of a dryer 500, the web B occurs; B '(or two parallel tracks B1, B2) from the dryer 500 and is z. B. supplied via guide elements 501 of the cooling unit 600. The guide elements 501 may in this case preferably be designed as guide elements 501 with air outlet openings for forming an air cushion for contactless web guidance. In contrast to turner bars whose longitudinal axis is perpendicular to the direction of the incoming web B; B '( Fig. 19 ).

Of particular advantage is an embodiment of the cooling rollers 601 with a large diameter, z. B. at least 300 mm, formed. Preferably, they have channels (in the longitudinal direction or in a spiral shape) through which they pass under their lateral surface.

Behind the last chill roll 601, a rewet device 602 may be disposed in the web path.

After printing and any subsequent painting, drying and / or cooling in the cooling unit 600, the web B runs; B 'for further processing into the superstructure 700. In the superstructure 700, the printed web B; B 'or the printed webs B1; B2 cut to the formats and further processing corresponding partial webs, placed in the required alignment and / or the desired position, and thus aligned and "sorted" the further processing in one or more folders 800 supplied.

In the present machine and procedure, it is of particular advantage to make several (part) products (identical, similar end products or sections of the same end product and / or completely different products) simultaneously.

In a simplest embodiment, this can be achieved by a folder 800 (with, for example, a folder) having only one exit 806, but a later separation of the successive products. This is z. B. thereby realized that the two (sub-) products forming strands 709 are laterally slightly offset in the folder 800 and therefore laterally in the display laterally offset from each other to come to rest. When using formers 708 in the superstructure 700, for example, two formers 708 are with their funnel tip in a projected in the horizontal direction of transport of the incoming web B; B '(longitudinal direction) relative to one another and offset for the above-mentioned operation ( Fig. 24 ). When using only guide elements 712, in particular turner bars 712 (eg. Fig. 20 ), the impact areas of the partial webs on the turning bars for the different strands to be assigned to the web strands can be chosen so differently that the alignment of the folding machine 800 running partial webs or web strands bx; by; bz of one to be formed (partial) product and those of the other to be formed (partial) product laterally slightly offset from each other, so that the one strand bundle laterally offset to the other strand bundle enters the folder 800.

The different products result here z. B. of circumferentially on the forme cylinders 304 successively arranged different, the various (sub-) products associated printed images.

In a further, somewhat more variable embodiment, a folding apparatus 800 may have a multiple folding apparatus 800 (800.1, 800.2) having a plurality of cylinder groups (eg two or three folding units, eg cylinder groups), each having one outlet 806 or having a plurality of outlets 806 on which the different products are designed ( Fig. 22 and 24 ).

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

A superstructure 700 having one or more formers 708 may be equipped with j formers 708 (j e N> 0) which are fixed or displaceable in the longitudinal and / or transverse direction. With j> = 2 folder 708, it is basically possible to separate the products lying inside one another in the shingled stream (longitudinally offset formers 708, see above).

In particular, in the present case of printing units 301 with printing cylinders 303; At least twice the circumference (ie at least four horizontal or vertical standard pages, eg DIN A4, one behind the other in the circumferential direction) are suitable for very flexibly processing products with vertical and / or horizontal sides. In this context, it is advantageous for flexible further processing to provide one or more variable size folders 800 (see below) and / or simultaneously multiple folders 800 (or a multiple folder) having different section lengths. A combination thereof and / or optionally an additional cutter can be particularly flexible enable.

For the different applications with the corresponding folders 800, an optimized superstructure 700 is preferably advantageous. Thus, for example, in one embodiment, a folder 800 with upstream in the strand path former 708 for the production of a product to be produced in cross-rupture with standing s (in the Fig. 37 . 38 . 39 and 40 z. T. marked with an orientation s) printed pages (hereby referred to as broadsheet arrangement s) on the forme cylinder 304 (in the manner of a newspaper with longitudinal and transverse fold) in conjunction with a second folding apparatus 800 for lying on the forme cylinder 304 (in an orientation I) I sides, preferably with added for trimming, for finished products in a tabloid, book or phone book format advantageous.

Also, a combined production of commercial products and / or telephone book products and / or books side by side and / or successively on the same machine is advantageous in terms of economy. For simultaneity, in the case of smaller product page numbers, no production with only part-wide webs B must be accepted.

Several or all sections of a final product, or different (sub) products, can be created in one machine run.

In the case of a superstructure 700 formed with formers 708, the arrangement of at least two formers 708 is advantageous in connection with a plurality of sections or products to be produced at the same time.

The superstructure 700 in each case comprises a longitudinal cutting device 701 through which the web B; B 'can be cut in one and / or two-sided printing partial webs bx or web strands bx. In the case of a printing unit 300 designed by default on eight DIN A4 pages arranged side by side, preferably at least seven knife units 705, printing unit 300 designed in one x (x = 6, 8, 10 or 12) juxtaposed DIN A4 pages has a number of at least x 1 blade units 705 provided transversely to the web direction side by side. At least a number of, but advantageously all the web B; B 'blade units 705 cutting in web cords bx are preferably in the direction transverse to web B; B 'arranged adjustable. The blade units 705 are z. B. each individually driven rotationally and / or individually on / off. Preferably, the blade unit 705 is 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 of the machine control automatically based on the intended width for printing the web B; B 'and the product-specific cut lines to be made or from a control panel or made automatically.

The superstructure 700 can functionally and / or structurally still 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 by a motor applicator rollers, possibly a scanning device for measuring the color density and possibly a perforating (only indicated by dashed lines) assigned and in particular the longitudinal cutting device 701 upstream. A further advantage is the arrangement of scanning heads for the color register control on both sides of the web B; B '.

In an embodiment of the superstructure 700 (hopper superstructure), not shown, the resulting web strands bx are all guided over the flanks of formers 708. So that the web strands bx can be displaced laterally in their flight, depending on the product requirements, one or more reversing corners 711 are provided with pairs of rotating turning bars 712 for displacing a number of part webs bx in front of the hopper unit 703 with one or more folders 708. The web strands bx guided via the former (s) 708 are then - folded or cut open at the longitudinal fold - fed to the folder 800 as a strand bundle.

In another embodiment of the superstructure 700 ("magazine superstructure" 700, eg Fig. 20 ), the resulting web strands bx are not passed through the former 708, but guided as einseitenbreite web strands bx on a turning 702, which -. B. transversely to the inlet direction side by side - at least a number of turning bars 712 which corresponds to the number x of maximum on a maximum width of web B side by side by default to be printed pages (eg., In horizontal or upright DIN A4 format) Fig. 20 and 21 ).

After deflecting the web strands bx by - projected into the horizontal - 90 °, the web strands bx pass through a register 706 with at least x-1 register rollers 707 before the summarized web strands bx combined to one or more common strands 709 and one or more downstream Folders 800 (800.1; 800.2) are fed.

In Fig. 20 Such a superstructure 700 is exemplified by a turning device 702 for a web B printed side-by-side with x = 12 printed pages. B 'shown. In Fig. 21 By way of example, a superstructure 700 is shown, which is abbreviated. B. two lanes B; B 'of two printing lines M a turning 702 with a total of 16, or two turning units 702, each with an exemplary x = 8 turning bars 712 has.

With such a wide printing press or web B; B 'can be at the same time with each revolution two identical products or two different partial products in each one folder 800.1; Create 800.2. This may be advantageous in view of the difficulties encountered in folding with increasing product strength (damage, accuracy, etc.). Likewise, as shown here two products of different page numbers can be produced simultaneously by -. B. from the web center of the exit web B; B 'starting - web strands bx variable to the strand 709 for one or the other folding apparatus 800.1; 800.2 can be added.

In a particularly advantageous embodiment, the two folders 800.1; 800.2 also be designed differently from each other. Thus, one folding unit 800.1 may be formed with one pin folder 800.1 and the other one folder folder 800.2 and / or one folder 800.1 with respect to a fixed-length processing capability for a first portion length and the other folder 800.2 may be configured for a different second portion length (see, for example, FIGS both folders 800.1; 800.2 in Fig. 23 with different distances between holding tools 802 of the respective transport cylinder 801, ie different section lengths) and / or the one folding apparatus 800.1 with regard to a fixed-format processing capability z. B. the standard product for a first section length and the other folding apparatus 800.2 as a folding apparatus 800.2 with variable section length (ie, for example, with acceleration section 807, see Fig. 36 ) and / or one folding apparatus 800.1 without and the other folding apparatus 800.2 may be formed with means for forming a second longitudinal or transverse fold.

In a third embodiment ( Fig. 24 ) of the superstructure 700 may be particularly advantageous from the first embodiment ("funnel superstructure" 700, with formers 708) and the second embodiment ("magazine superstructure" 700, without formworker 708). Here, in addition to the turning 702 a hopper unit 703 with at least one former 708, and a strand path of turning bars 712 via a former 708 to a folding apparatus 800.1; 800.2 and a strand path of turner bars 712 without an in-line former 708 to the same or
another folder 800.1; 800.2 provided. The former 328 may be preceded by one or more turning tables 711 in the web path. With the mixed version, it is possible, in an operating situation, only single-sided web strands bx via the turning device 702 to a folding apparatus 800.1; 800.2 supply, or in another operating situation one and / or two-sided web strands bx exclusively on the former 29 to lead and longitudinally fed a folder, or in the third operating situation einseitenbreite web strands bx on the turning 702 and one and / or two-sided web strands on the former 708 to lead. As a result, two different products (eg a newspaper-like longitudinally folded product with printed pages of a first format A in broadsheet arrangement s on the forme cylinder 304 and a tabloid or book-like product of a second format A, for example in tabloid arrangement I (FIG I) on the forme cylinder 304) in two subordinate folders 800.1 provided for this purpose; 800.2 are produced. In the latter case, the two differently processed web strands bx of two different webs B; B 'different print lines M come. In a special and advantageous embodiment, however, the two different formats A, z. Eg A4 and A3 formats; Z side by side on longitudinal sections of a same forme cylinder 304 or side by side as print images on a same web B; B 'be arranged. For example, printed images of a stationary newspaper or magazine format can be arranged on a longitudinal section of a same forme cylinder 304, while print images of another stationary newspaper / magazine format or horizontal printed pages of a tabloid format are arranged on another longitudinal section. Through the first longitudinal section -. B. in vertical arrangement - printed web strands bx are, for example - at least partially - cut in two-sided width web strands bx, longitudinally folded, in a folder 800.1; 800.2 cut to sections with a length corresponding to a standing pressure side transversely folded and delivered to the display, while, for example, by the second longitudinal section -. B. in horizontal arrangement - printed web strands bx, for example, cut into single-side web strands bx, passed over the turning mill 702, in a folding apparatus 800.1; 800.2 to sections with a length corresponding to two lying printed pages are transversely cut and folded transversely.

For the examples with two folders 800.1; 800.2 may have a back-to-back arrangement (as in Fig. 24 ), a head to head arrangement (like Fig. 25 ) or alignment in the same direction. In the latter case, it may again be advantageous to use the two folders 800.1; 800.2 to offset each other in height or to use a designed as a double folder folding machine 800 with two vertically offset folding cylinder groups.

According to the invention, at least one of the folders 800.1; 800.2 designed as a folding unit 800 with variable section length. This points - as in Fig. 36 schematically illustrated - a transport cylinder 801 upstream cross cutting device 811 and an acceleration section 807 for the cut product sections 808 (signatures) -. B. by means of a tape system 809 - on. The equidistant distances of holding tools 802 on the transport cylinder 801.z. B. gripper or Punkturzylinder 801, at least correspond to the longest to be printed in the web running direction printed image. The transport cylinder 801 including belt system 809 is designed so that it can be operated with a relation to the uncut strand 709 higher conveying or peripheral speed, while z. B. the upstream units 300 are operated substantially with the not yet transversely cut strand 709 promotional speed / peripheral speed. Depending on the relative peripheral speed of the cross cutter 811 and cylinder rotation of the transport cylinder 801 set to the still uncut strand 709, longer or shorter product sections are cut off, accelerated, and picked up by the holding tools 802 (eg, grippers or pin bars 802, the transport cylinder 801) is therefore suitable for processing different side lengths of printed pages arranged on the forme cylinder 304 as section lengths in two different operating situations, for example printed page sections of the same format (eg DIN A4 format) lying in one operating situation and standing in another operating situation or, in a first operating situation, pressure side sections having a length of a first integer divider (eg three or six) of the forme cylinder circumference, and in another operating situation pressure side sections mi t is a length of a second, different from the first integer divisor (z. B. two, four or eight) of the form cylinder circumference.

Below are shown schematically advantageous embodiments with web strand guide for the execution of the superstructure 700 in combination with the folding apparatus 800 or folders 800:

Fig. 26 shows a so-called magazine superstructure 700 with a number x, z. B. x = 6, web strands bx, which are cut longitudinally by x-1 blade units 705 and guided over x turning bars on each other and one or more here not visible folding apparatus (s) 800 are supplied. The / the folder (s) 800 is / are here z. B. oriented so that the axis of rotation of the transfer cylinder 801 perpendicular to the axis of rotation of the upstream printing cylinder 303; 304 or projected in the horizontal direction of transport in the folder 800 across the machine alignment M ("machine axis") runs. The web strands bx have in their width z. For example, in each case only one printed page - in particular a horizontal printed page (eg., DIN A4 format) on. For several folders 800.1 arranged underneath; 800.2, the partial webs bx can be split into two strands 709 and simultaneously two folders 800.1; 800.2 (or two groups of folding cylinders of a double folder 800.1; 800.2). The turning bars 712 may be cantilevered in this embodiment or the following embodiments or be supported on both sides by a frame indicated by dashed lines. One, several or all turning bars 712 can advantageously over a setting range transverse to the incoming web B; B 'or partial web bx be movably mounted.

Fig. 27 shows a superstructure 700 designed as a so-called funnel superstructure 700, wherein, however, the former (s) 708 has a running-on direction projected in the horizontal direction, which runs perpendicular to the machine alignment M. A number x, z. B. x = 6 or in cross-break production z. B. x = 3, web strands bx, which are cut longitudinally by x-1 blade units 705 x crossing rods 712, over one (or possibly divided over several) Former 708 out, and one or more folding (s) 800 to form a Cross fold supplied. The folder (s) 800.1; 800.2 is / are here z. B. oriented so that the axis of rotation of the transport cylinder 801 parallel to the axis of rotation of the upstream printing cylinder 303; 304 or projected in the horizontal direction of transport in the folder 800 parallel to the machine alignment M ("machine axis") runs. The web strands bx point in front of the turning bars 712 in their width z. B. two printed pages - z. B. two horizontal printing page (eg., A4 size) on. In a broadsheet or cross-hatch production, the two-side wide web strands bx are folded longitudinally over the former 708 and fed to the folder 800 or multiple folders 800 for the transverse cutting and transverse folding. In tabloid production (for example printed pages lying on the forme cylinder 304), the web strands bx between the turning bars 712 and the former 708 can be cut into one-side-wide web strips and placed on top of each other by the former hopper 708. For multiple folders ("FA") below 800.1; 800.2, the partial webs bx can be split into two strands 709 and simultaneously two folders 800.1; 800.2 (or two groups of folding cylinders of a double folder 800.1; 800.2).

Fig. 28 shows the simultaneous production of two different products or partial products or product formats by means of a hopper superstructure 700 and two folders 800.1; 800.2 from a same printed web B; B ':

Here, the web B; B 'into a number y web strands by having a first web width (and / or first print page orientation and / or a first print page format) and a number of z web strands bz having a second web width different from the first web width (and / or second print page orientation and / or a second printed page format) - possibly according to the respective print image widths - cut. The web strands by; bz different widths (or printed page formats and / or - orientations) are now combined into strands 709 and different folders 800.1; Fed 800.2. In this case, for example, the broader web strands are longitudinally folded over the former 708.1 and further processed in a first folder 800.1 to a cross-break product (eg., In the manner of a newspaper), while z. B. einseitenbreite web strands bz superposed on the other former 708.2 and in the second folder 800.2 to a tabloid product (eg., To a substantially A4 product) are further processed (shown in phantom). In the second strand path, the former 328.1; 708.2 also omitted, the folder 800.2 then possibly rotated by 90 ° for display is arranged. In Fig. 28 For example, possible orientations of horizontal (tabloid) printed pages and upright (broadsheet) printed pages are indicated. In Fig. 28 are the casserole directions (see arrows) 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.

Fig. 29 shows an arrangement according to Fig. 28 However, wherein the running directions 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 in terms of a backup function, since without much effort a same product with the same occupancy of the cylinder 304 on one or the other folder 800.1; 80.2 can be produced.

Fig. 30 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 708.1; 708.2.

Fig. 31 shows an advantageous embodiment, wherein a projected into the horizontal direction baking direction on the / the former 328.1; 708.2 parallel to the machine alignment M and / or perpendicular to rotation axes of the printing cylinder 303; 304 runs. The folder (s) 800.1; 800.2 is / are here z. B. oriented so that the axis of rotation of the transport cylinder 801 perpendicular to the axis of rotation of the upstream printing cylinder 303; 304 or projected in the horizontal direction of transport in the folder 800.1; 800.2 runs transversely to the machine alignment M ("machine axis"). In this example, again an operating situation is shown in which, for example, printed pages of different width / orientation onto the web B; B 'are printed, and these in different widths web strands by; bz cut, and simultaneously to two different products (intermediates) in two folders 800.1; 800.2 be further processed. The two folders 800.1; 800.2 may be formed on a same plane, offset vertically from each other, or as a folder 800 having two folding cylinder groups and two trays.

Fig. 32 shows a schematic front view of a magazine superstructure 700 (without former) with a downstream folding apparatus 800 - comparable to an embodiment according to Fig. 26. to 33 in contrast shows a hopper superstructure 700 with a former 708 between turning bars 712 and the folding apparatus 800.

Fig. 34 shows a schematic front view of a magazine superstructure 700 (without former) with two downstream folders 800.1; 800.2. 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 Fig. 35 schematically the case for a hopper superstructure 700 with two formers 708 and two folders 800.1; 800.2, wherein two strand bundles of web strands bx; by; bz over the formers 708 out, and at the same time two folders 800.1; 800.2 be supplied. As indicated by the 'crossing', one, several or all of the web strands bx; bx; bz can be transferred from one bundle to the other (for example in order to be able to realize correspondingly different section or product strengths.) A stapling device can also be used on individual strands In order to be able to remove a part of the layers from the later product as a stapled booklet, the folding devices 800.1, 800.2 arranged offset on one another can also be arranged at the same height next to one another.

With only one folder 800 has this, or in two folders 800.1; 800.2 at least one of the folders 800.1; 800.2, preferably in addition to the first transverse folding device (eg transport cylinder 801 with folding jaw cylinder 814 designed as folding blade cylinder) downstream of a means for forming a second transverse fold 803 and / or a means for forming a longitudinal fold 804. This is exemplary in Fig. 24 however, each is shown on one of two folders 800.1; 800.2 or the single folder 800 of the remaining examples apply.

Fig. 37 shows advantageous production possibilities with a printing unit line M (or a web B), the printing cylinder 303; 304 has a width of 12 and a perimeter of four upright A4 pages (for dimensions, see for example above) and two folders 800.1; 800.2 or a folder 800 with two folding cylinder groups and two displays are arranged downstream:

In the illustration, a raster for the occupancy with standing DIN A4 format print images is at the top center, obliquely hatched an exemplary representation of a tabloid page T, z. B. in A3 format, and with crosshatch an exemplary representation of a stationary page in a DIN A2 format or corresponding newspaper format Z or newspaper-like print image format Z indicated.

The two tables shown under the folders 800.1 and 800.2 indicated 800 indicate advantageous productions. From a lane B; B '; B1; B2 are each a product example of a line of the first table by the first folder 800.1 and at the same time a product example from the same line of the second table with the second folder 800.2 maximum produced. It is advantageous, for example, if for a mode of operation in standard production with homogeneous form cylinder occupancy, d. H. arranged on the form cylinder jacket printed pages of a single same format with a uniform orientation, at the first folder 800.1 a partial product of 48 DIN A4 pages and the second folder 800.2 also a partial product of 48 DIN A4 pages are designed. These two sub-products can then represent two identical products in the same half-repeated on the plate cylinder 304 in the longitudinal direction repeating or mirror-symmetrical print image assignment, in the first case, an arrangement z. B. with anti-parallel Falzapparat- and / or funnel arrangement (see above) and in the second case z. B. with parallel folder and / or funnel arrangement (see above) may be provided. With different print image occupancy of the cylinder halves two parts of a total product or two different products can be produced. A further advantageous production variant with three sub-products having the same number of pages can be produced if, for example, on one folding apparatus 800.1 two unsorted 32-page partial products (from four double-sided or 8 single-page strands), and on the other folding apparatus 800.2 an unsubsulated 32-page partial product (from two double-sided or 4 single-sided strings) is generated and designed. If all the strands of the superstructure 700 (in this case two strand strands bx; bx; bz are denoted as strands of two DIN A4 pages) are applied to a folding apparatus 800.1; 800.2, a product with 96 DIN A4 pages can be produced in collective production (marked with »in the tables).

Particular advantages arise in production with inhomogeneous cylinder occupancy, ie with an occupancy of the forme cylinder 304 side by side with different print image formats -z. Standing format A4 (eg DIN A4) and lying tabloid in A3 format (eg DIN A3), or standing print image formats A of different sizes, eg. B. standing DIN A4 page (A4 format) with upright DIN A2 page (A2 format) or a newspaper-like Z format (can advantageously correspond to A2 format): So, for example, a production of advantage, in which in addition to a above A4 production (with standing A4-Druckseiten) on the first folding apparatus 800.1 at the same time a production of products in TabloidformatT is possible (in table exemplarily for two cases with * marked lines). For example, on one folding machine 800.1, a DIN A4 product of 2 x 32 pages (unkempt) or 64 pages (collected), and at the same time a 16 page tabloid product (or 2 x 8 pages unsorted) are laid out on the other folder 800.2 become. In this case, they share the same path B; B 'produced strands as indicated in each case in column 1 in four or two, each with a corresponding width -. B. a standing DIN A4 or two standing DIN A4 pages corresponding tabloid. The assignment with the different print images on the forme cylinder 304 takes place in each case according to the screening in the required strands. In Fig. 38a ) is an example of the above inhomogeneous assignment (2 x 32 or 64 A4, 2 x 8 or 16 pages tabloid) in the representation of a rolled-out forme cylinder 304 or a repeat length of a printed web B; B 'given by way of example. The remaining variants for inhomogeneous A4 / tabloid production should be applied accordingly.

In Fig. 38b ) 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 s of the printed image in a newspaper-like format Z or A2 format. For example, in this example, four of the two-A4 widths "strands" are printed in the manner of pages in newspaper format Z. These four "strands" need not be in four, but can be divided into only two two-sided web strands bx; bx; bz cut, and the two each two-newspaper page width web strands bx; bx; bz over each other via a former 708 are fed before they run into the folder 800.2.

In an in Fig. 38c ) indicated by way of example, z. B. in addition to the standard A4 product (print page of a format A), with z. B. in the circumferential direction of a number of multiples of two), for example, another DIN A4 format deviating format (eg., Special format S, for example, in the circumferential direction a multiple of three corresponding number of printed pages here in the circumferential direction three printed pages of a standing Special size S2 or six printed pages of a special size S1 (see also Fig. 39 ), at the same time on the web B; B 'printed and in two folders 800.1; 800.2 processed. In the width direction of the forme cylinder 304, the print images may not have to reach the end of the effective bale. This production variant is to be used especially in connection with a folder with variable section length. Thus, the first folder 800.1, for example, as a fixed-format Punkturfalzapparat for a fixed standard format, eg. B. A4 size A4, and the second folder 800.2, for example, formed as a variable-format folder 800.2. The latter can be operated with the corresponding requirement, depending on the mode of operation and occupancy (homogeneous / inhomogeneous) of the machine.

Fig. 39 shows an overview of advantageous production options according to the principle of mixed production Fig. 38c) with printing pages on the forme cylinder 304 differing in format and / or orientation. Thus, simultaneously from the same web B; B '(partial) produce products that z. B. are located in a same row of the two tables. On the one folder 800.1 can then z. B. a number y of partial webs by to usual products in DIN A4 format A4 are produced, while on the other folding apparatus 800.2 from a number z of partial webs bz from the same printed web B; B 'Products with horizontal or vertical printed pages of a special format S1; S2 or even one of the first format A4 different format, eg. B. format A3 or even A2, are produced. The corresponding number z of the partial webs bz then depends on the page width of the printed image of the special format S; S1; S2 or formats A2; A3 and / or after its orientation s; I and, if appropriate, whether the printing cylinder cylinders 304; 303 are formed with an addition to the defined by the maximum number of DIN A4 pages side by side nominal width width b304. In the table is an example of the example Fig. 38c ), whereby in this table row y = 4 partial webs by in the format a4 with vertical orientation s and z = 3 partial webs bz in a horizontal special format S1 or a standing special format S2 are printed and processed. Here, the first folder 800.1, for example, as a fixed-format folder 800.1 with a substantially two standing pages in A4 format or a half circumference u304 of the forme cylinder 304 corresponding section length on the transport cylinder 801, and the other folder 800.2 either as a variable-format folder 800.2 or with a Special format S1; S2 corresponding section length of z. B. a third of the circumference u304 of the forme cylinder 304 is formed.

In an also marked advantageous production example are (see corresponding table lines) y = 3 partial webs z. For example, two A4 uncollected 24-page products or one 48-page A4-sized stock collected in s, or two 12-page unsorted 12-page A3 or T products, or a collected 24-page product. Product in A3 or T format with horizontal orientation printed and processed - depending on page width of the second format, eg. B. a special format S; S1; S2 or another format A2; A3, z = 3 or z = 4 or z = 5 partial webs bz in a lying special format S1 or a standing special format S2 to products with a corresponding, collected by the operating mode or unsorted dependent page number, printed and processed. This can then be z for z = 3 partial webs z. For example, there may be three 12-page uncollected products or one 36-page collected product in the recumbent special format S1. For z = 4 partial webs bz, this can advantageously be three unsorted products of 16 pages each or a collected product of 48 pages in the lying special format S1. Other alternative product options are apparent from the tables in the manner exemplified.

Of advantage is an embodiment, wherein from a web B a plurality of sub-webs by with in the circumferential direction of the forme cylinder 304 and per printing length four stationary printed pages of a first format A; A4, in particular with DIN A4 format A4, and a plurality of partial webs bz with in the circumferential direction of the forme cylinder 304 or each printing length six lying print pages of a second format A, z. B. a DIN A format A5, in particular z. B. a special format S1, carry, these different partial webs each as a bundle in two different folders 800.1; 800.2 (see above).

An advantageous embodiment, not shown, has a number y of partial webs by z. B. pages in A4 format in the above manner, while a number z of sub-webs bz, as in Fig. 38b ) shown schematically, mitz. B. a standing newspaper or magazine-like format Z in standing orientation, z. B. three standing pages in a row, has. In this case, it may be expedient to guide these partial webs bz over a former hopper 708 before they are fed to the downstream folding apparatus 800.2 to form a transverse fold. One or more of these second partial webs bz can then have a width in front of the former 328, which has two printed pages of the format Z next to one another.

In Fig. 40 The conditions for the production possibilities are correspondingly up to Fig. 37 however, for a printing unit line M, its printing cylinder 303; 304 has a width of 12 and a perimeter of six upright A4 pages (dimensions see eg above) and two folders 800.1; 800.2 or a folding apparatus 800 are arranged downstream with two Falzzylindergruppen and two displays. 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 T, and indicated by cross-hatching an exemplary representation of a stationary page in a DIN A2 or corresponding newspaper Z format.

In the Fig. 38 The principles described above are to be transferred directly to this case, wherein due to the larger circumference in the circumferential direction correspondingly more of the pages shown in each format A4; T; Z; S are to be arranged. In one too Fig. 38c ) comparable operating situation, can here as a special format S, for example, in the circumferential direction a multiple of four 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 while a standard format, z. B. A4 is printed with six printed pages on the circumference.

In the special, o. G. Execution of a supply of two webs B1; B2 side by side by the printing units 300, in the aforementioned examples, a longitudinal section between two web strands bx; by; bz omitted, since here the joint of the two tracks B1: B2 runs.
