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

The object is achieved by the features of claim 1.

The achievable with the invention advantages are in particular that a simple, inexpensive and space-saving design with high variability in the product or intermediate product is made possible.

In particular, there are also advantages in that, compared with a double-width printing press, the production reliability is considerably increased at 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. 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 at least over a section length always a closed lateral surface with the shape or. Satellite cylinder acts together. Third, roundness and manufacturing costs are minimized by the fact that although the bales are provided on its entire effective length axially passing channels, but openings exist to the lateral surface only in the said sections. In the channels then z. B. optionally used devices for attachment of elevator ends and / or patches.

In the channel or in the channels of the forme cylinder, in each case at least six devices for the axial positioning of printing plates are arranged in the axial direction. These are z. B. designed as a form-fitting with pressure forming ends cooperating register pins which are arranged axially movable manually or remotely operable within the channel.

The execution of the printing units with associated pressing devices is advantageous in terms of a register-accurate or register-accurate reproducible equipping the form cylinder with printing plates. It can be fixed with these resting on the lateral surface of the cylinder lifts by at least one pressing element as needed, while one end of an elevator or more elevators for removal or assembly is released or are.

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. In an advantageous embodiment, each printing tower (or eight printing locations) is provided with two register devices movable transversely to the direction of travel of the paper to compensate for paths of the partial webs. These can be structurally connected in each case with a part-web-wide turning devices. Also subsequent, only partial webs associated guide elements are z. B. executed essentially only partial web width substantially. These designs allow a low-vibration, and thus tailor-made transport of the web. By inertia long, strong, caused only by the sub-web (s) guide elements caused web tension fluctuations (for example, load changes, change in printing speed) can be effectively reduced.

With regard to a reliable operation and a cost-saving design, it is also advantageous to provide in the superstructure the possibility of turning a partial web by an odd multiple of half a partial web. Thus, a retraction and printing of partial webs with half a funnel width (eg a newspaper page) can be omitted.

In terms of cost and space-saving design, it is in an embodiment of advantage, only one of two stacked formers a so-called. Harp, d. H. several i. d. R. ungetriebe Auflaufwalzen, vorzuordnen. On the other former, webs from the harp can be transferred. The two vertically stacked formers can be supplied from the same escape of superimposed sub-webs strands of variable thickness or partial web number.

In one embodiment, sub-webs from one of a funnel group associated harp of the other funnel group can be acted upon and vice versa. In an advantageous embodiment, only one of two stacked formers is a so-called harp, ie several id ridden idler rollers (also called collection or take-off rollers), vorzuordnen. On the other formers then tracks from the common harp can be transferred. The two vertically stacked formers can be supplied from the same escape of superimposed sub-webs strands of variable thickness or partial web number.

In an advantageous embodiment of a turning device, the partial web is displaceable or offset only by an odd multiple of half the partial web width. So it can be z. B. avoid with little effort to print very narrow webs or provide additional printing units. The transversely movable to the web execution at least one of the turning bars allows a high variability.

The mechanically independent of the printing units drive rollers of the hopper structure and / or the folding apparatus is particularly advantageous in terms of a good registration and a variable operation.

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

In the case of the satellite printing unit 02, the satellite cylinder or cylinders 18 are likewise rotationally drivable by a drive motor 61, mechanically independently of the associated printing units 13. The drive motors 61 are preferably as with respect to their angular position controlled electric motors 61, z. B. as induction motors, synchronous motors or DC motors. In an advantageous embodiment is between the drive motor 61 and the driven cylinder 16; 17; 18 or cylinder pair 16, 17; 18, 18 at least one gear 62, in particular at least one reduction gear 62 (such as pinion, intent and / or planetary gear) arranged. The individual drives contribute to high flexibility and to avoid vibrations in the mechanical drive system, and thus also to high quality in the product. In the following FIGS. 8 to 10 have only the components of the right half of the figure corresponding reference numerals, since the left side corresponds to the right mirror image. There are in each case for upper and lower printing units alternative configurations for possibly existing inking or dampening 14; 20 indicated, which are to be transmitted alternately to each other.

In Fig. 8 all nine cylinders have 16; 17; 18 each have their own drive motor 61, which in each case z. B. via a gear 62 on the cylinder 16; 17; 18 drives. The inking unit 14 shown above has, in addition to other, unspecified rollers on two distribution cylinders 63 which are rotationally driven together by means of a separate drive motor 64. The two distribution cylinders 63 are axially movable and driven by an unillustrated drive means for generating an axial stroke. The inking unit 14 shown below has only one distribution cylinder 63. The dampening unit 20 shown above has, in addition to other, not designated rolls on two distribution cylinders 66 which are rotationally driven together by means of a separate drive motor 67. The two distribution cylinders 66 are axially movable and driven by an unillustrated drive means for generating an axial stroke. The dampening unit 20 shown below has only one distribution cylinder 66. In a variant which is indicated in the upper printing units 13 by dotted lines, the inking and / or dampening unit 14; 20 not by its own drive motor 64; 67, but from one of the cylinders 16; 17; 18, in particular from the forme cylinder 16 ago via a mechanical coupling, z. B. via gears and / or belts, rotationally driven.

In contrast to Fig. 8 the two cylinders 16; 17 each printing unit 13 in the execution to Fig. 9 each driven by a common drive motor 61 on the transfer cylinder 17. The drive can be axial, z. B. via a gear 62, done or via a on a drive wheel of the transfer cylinder 17 driving pinion. From the drive wheel of the transfer cylinder 17 can then be driven off to a drive wheel of the forme cylinder 16. The drive connection 68 (shown as a connecting line) can be made as a gear connection or via belt and is executed encapsulated in development. For the drive of the color and possibly dampening unit 14; 20 via their own drive motors 64; 67 or a cylinder 16; 17; 18 is basically the too Fig. 8 applied.

In contrast to Fig. 9 the two cylinders 16; 17 each printing unit 13 in the execution to Fig. 10 Although each of a common drive motor 61, but driven on the forme cylinder 16. The drive can again axially, z. Example, via a gear 62, done or via a on a drive wheel of the forme cylinder 16 driving pinion. From the drive wheel of the forme cylinder 16 can then be driven off to a drive wheel of the transfer cylinder 17. The drive connection 68 may as well Fig. 9 be explained set forth. For the drive of the color and possibly dampening unit 14; 20 via their own drive motors 64; 67 or a cylinder 16; 17; 18 is basically that too Fig. 8 applied.

Unlike the in Fig. 8 or 9 indicated by dotted lines execution without own rotary drive of the inking and / or dampening unit 14; 20, it is advantageous in a development, from the transfer cylinder 17 to the inking and / or dampening unit 14; 20 to drive. Thus, a clear moment flow can be achieved and possibly occurring tooth flank changes can be avoided. An embodiment of such a drive train is shown schematically in FIG Fig. 11 shown.

The drive motor 61 drives via a pinion 71 on a rotationally rigidly connected to the forme cylinder 16 drive wheel 72, which in turn drives on a torsionally rigidly connected to the transfer cylinder 17 drive wheel 73. The drive wheel 73 is either widened or it is a second drive 74 with the transfer cylinder 17th connected. The widened or additional drive wheel 73; 74 drives via a rotatably mounted on a pin 76 of the forme cylinder 16 drive wheel 77 on a drive wheel 78 of the inking and / or dampening unit 14; 20. The drive wheels 72; 73; 74; 77; 78 are preferably designed as gears. In the event that the forme cylinder 16 is axially displaceable in an axially displaceable manner by, for example, ± ΔL, at least the pinion 71 and the drive wheels 72 to 74 are made straight toothed. Between drive motor 61 and the gear 62 of pinion 71 and drive wheel 72 may additionally be a dashed lines indicated, encapsulated auxiliary gear 62 'may be arranged. Alternatively, the drive to the forme cylinder 16 can also take place axially on the journal 76, wherein, if appropriate, an axial movement of the forme cylinder 16 takes place via an unillustrated, axial relative movement between the forme cylinder 16 and the drive motor 61 receiving coupling. The satellite cylinder 18 is also driven in this illustration via a pinion 71 on an associated drive wheel 79, in particular gear 79. Each driven by an independent drive motor 61 drive train is in an advantageous embodiment, at least for itself, possibly in even smaller units, encapsulated (stichliiert in Fig. 11 shown).

The described embodiments of the printing unit 02 and the printing units 13 and their cylinders 16; 17; 18 and the drive allows a low-vibration, accurate printing high quality with a low on the achievable product strength technical and spatial complexity.

After printing the z. B. six printed pages wide web 03 runs this, possibly via unspecified baffles and / or draw rollers, in the area of the superstructure 04 and z. B. guided by the slitting devices 06 ( Fig. 12 ). This has z. B. a roller 81, for example, a driven by its own drive motor 80 pull roller 81, with which pressure rollers can work together to avoid slippage. Slitter 06 and the draw roller 81 may also be carried out separately, but preferably with the Longitudinal cutting device 06 as reemployment another roller acts together. In this longitudinal cutting devices 06, the web 03, for example, in several, z. B. three, partial web widths 03a; 03b; 03c, short part tracks 03a; 03b; 03c (symbolized by center lines, lines 03a, 03b merely indicated), cut longitudinally before these partial webs 03a; 03b; 03c subsequent guide elements, for. As rolls of registering devices 08, turning bars of turning devices 07, run-on rollers for the funnel inlet or draw rolls are supplied. In order to achieve a low-vibration web transport with respect to the web tension, individual, several or all non-driven or only by friction with the web 03a; 03b; 03c driven guide elements which are used to guide partial webs 03a; 03b; 03c are provided are executed with a reduced length. Thus, in addition to the length of the otherwise for z. B. six pages wide machines large required strength of the vanes and thus significantly reduce the inertia. The risk of vibrations in the web tension, which otherwise exists in particular when there is a change in speed, is effectively reduced, which in turn is reflected in the passer-loading and thus in the quality of the print. The following remarks on the guide elements of reduced length, the lateral location changeability and the assignment of a register roller to another guide element are to be applied to a variety of printing machines, but of particular advantage i. V. m. wide, z. B. six plates wide machines.

Fig. 12 shows in a perspective oblique view, a first embodiment of at least a portion of the superstructure 04. Exemplary is in Fig. 12 the partial web 03b shown as turned from the center to the outside part web 03b. A second of the partial webs 03a; 03c could also be turned into another flight, for example, by means of a second such turning device 07. A second turning device can, for.

The turning bars 82 advantageously have a length L82, the projection of which on the transverse extent of the incoming partial web 03a; 03b; 03c insignificantly larger, z. B. 0% to 20% greater than the width of the incoming partial web 03a; 03b; 03c is, d. H. the length L82 is approximately 1.4 to 1.7 times the partial web width. At least the length L82 is selected such that its projection is less than or equal to twice the width of a two-side width partial web 03a; 03b; 03c is, d. H. the length L82 is at most 2.8 times the partial web width. In an advantageous embodiment, the turning bars 82 are each mounted individually on carriers 83, which transverse to the direction of the incoming partial web 03a; 03b; 03c can be moved on at least one guide 84. The now "short" turning bars 82 can now bring depending on the requirements of the desired web guide in the required position. Under certain circumstances, both turning bars 82 may be mounted on such a carrier 83.

At least the length L88; L93 ( Fig. 13 ) smaller than or equal to twice the width of a two-side wide partial web 03a; 03b; 03c. In the embodiment according to Fig. 12 For example, the "short" harp roller 88 is realized as a section 88 of a harp roller 89 which is divided in this embodiment but extends over a total of six printing pages wide web 03. The sections 88 are rotatably supported independently of each other here.

The "short" harp roller 88; 93 as a guide element 88; However, instead of or in addition to a section 88, FIG. 93 may also, as in FIG Fig. 13 shown, as individually arranged on a frame harp roller 93 executed. This can then either fixed to the frame, or on a support 94 on a guide 96 transversely to the direction of the incoming part of the web 03a; 03b; 03c be arranged variable in location.

Since the offset when turning, shifting, falls, etc. only this part of the web 03a; 03b; 03c and is tied to their special web guide, in an advantageous embodiment, the required register device 08 at least one of the run of Partial web 03a; 03b; 03c determining guide elements, such. B. the turning device 07 or a turning bar 82 or the harp 09 or a "short" harp roller 93, are assigned.

In Fig. 13 is the "short" register device 08 z. B. the "short" harp roller 93 and along with this on the guide 96 transversely to the direction of the incoming part of the web 03b; 03c adjustable.

In Fig. 14 is the "short" register device 08 z. B. associated with one of the "short" turning bars 82 and together with this on the guide 84 transversely to the direction of the incoming part web 03b locally variable. Although this arrangement is shown here for crossed turning bars 82, but on parallel turning bars 82 from Fig. 11 apply. In the case of the crossed or mutually orthogonal turning bars 82 is at least one (here two) guide roller 97 with perpendicular to the axis of rotation of the roller 81 extending axis of rotation.

The guides 84; 96 ( FIGS. 13 and 14 ) of the aforementioned embodiments can be realized in many different ways. For example, the guides 84; 96 be designed as spindles with at least sections threaded, which rotatably mounted on both sides and z. B. are rotatably driven by a drive, not shown. The carriers 83; 94 can in the manner of sliding blocks in rigid guides 84; 96, z. B. on profiles, be performed. In this case, a drive of the carrier 83; 94 also via a drivable spindle or otherwise done.

By means of the transversely adjustable turning bar 82 are variable transfers or offset of partial webs 03a; 03b; 03c over one or two partial web widths (or even multiples of a half partial web width) away possible. Here, the printed partial webs 03a; 03b; 03c in the flight of one of several, here three, transverse to the direction of juxtaposition of the former 101; 102; 103 ( Fig. 15 ) of the folder assembly 11. The transfer takes place, for example, to meet the requirement of different strengths of individual strands or ultimately intermediate or end products, at the same time an effective printing with the fullest possible web widths should be made.

For n full tracks to be printed 03; 03 '(eg n printing towers 01) of a respective maximum width b03 of m printed pages, the superstructure 04 advantageously has at least (n * (m / 2 - 1)) turning devices 07. In the case of a six page wide printing machine and z. B. three tracks 03; 03 '(or three printing towers 01) per section are six turning devices 07 per section of advantage.

B. two sections of two printing towers 01 and a total of four provided for the two-sided four-color printing six printed pages wide webs 03; 03 '; For example, four turning devices 07 per section are arranged in this printing press In this printing press with two sections or a total of four printing towers 01 (four webs 03, 03 '), a product with a total thickness of 96 pages can be produced in the collective operation.

In addition to the offset of a partial web 03a; 03b; 03c is an integer multiple of his Part track width b03a, an operation is advantageous, wherein a partial web 03a; 03b; 03c is offset by an odd multiple of half the partial web width b03a and / or funnel width (ie by a factor of 0.5, 1.5, 2.5) ( Fig. 15 ). This can be done by means of long over the entire width of the printing press or the width b03 of the entire web 03 reaching turning bars (not shown), but also advantageously by means of the above-described portable "short" turning bars 82. The turning bars 82 are then, for example, as in Fig. 15 shown arranged so that the first of the partial web 03a; 03b; 03c looped turning bar 82 at least over an entire width of a subsequent folding former 101; 102; 103 is aligned, while the second turning bar 82 at least with two adjacent halves of two juxtaposed subsequent formers 101; 102; 103 is aligned.

The partial track 03a offset by an odd multiple of half the funnel width b101 or partial track width b03a; 03b; 03c thus runs "between" the formers 101; 102; 103. This is in Fig. 15 and 16 on the example of the six printed pages wide funnel arrangement on a two-side-wide sub-web 03a; 03b; 03c shown, but also to transfer to machines of other widths. There is thus no need for only one printed side wide partial webs 03a; 03b; 03c or partial webs 03a; 03b; 03c half a funnel width b101 printed as such and are passed through the machine. A high variety in the product is nevertheless possible.

The part track 03a offset by an odd multiple of half the part track width b03a; 03b; 03c is in front of the former 101; 102; 103 in a between the two aligned folding hoppers 101; 102; 103 longitudinal flight cut and runs on the folding structure 11 and the harp 09, ie undivided and / or split harp roller 89 and / or "short" harp roller 93 to ( Fig. 16 ).

In Fig. 16 is a schematic section of the Fig. 15 with exemplary differently executed harp rollers 89; 93, wherein, for example, the partial web 03c from their original position (shown unfilled) was offset by one and a half partial web widths b03a. It can, for example, if they are provided with a further longitudinal cutting device 104 in front of the formers 101; 102; 103 is cut (then in each case one printed page or newspaper page wide), each half in each case with the partial webs 03a and 03b on each of a former 101; 102 are led. The two (intermediate) products then have z. B. in each case at least one pressure side wide partial web 03c1; 03c2 a previously two printed pages wide sub-web 03a; 03b; 03c on. In addition, partial webs 03a '; 03b '; 03c 'from others, z. B. in another printing unit 02 or another printing tower 01 printed webs 03 'on one or more of the harp rollers 89; 93 accumulate. The sub-webs 03a, 03a ', 03c1 running over or under one another in the same flight; 03b, 03b ', 03c2; 03c 'can now z. B. each to a strand 109; 111; 112 summarized a former 103; 102; 103 are supplied. In the exemplary embodiment, it is therefore possible to use two webs 03, each printed on both sides, in double-size and three-width printing units (for example four-color). 03 'produce products or intermediates (also called books or books) with the following, depending on the occupancy of the forme cylinder 16 and the corresponding operation of the folder 12 different number of pages: In single production, ie the forme cylinder 16 is in the circumferential direction with two printing plates 19 different Printed pages A1, A2 to F1, F2 (or A1 ', A2' to F1 ', F2' for the second web 03 ') occupied and takes place in the folder 12, a cross-cutting and collecting, so are on the strands 109 and 111 respectively two different booklets each with 10 printed pages, and over the strand 112 two different booklets each with 4 printed pages generated. A total product has z. B. 48 pages. If this printing machine is operated in double production, ie the forme cylinder 16 is in the circumferential direction with two printing plates 19 same printed pages A1, A1; to F1, (or A1 ', A1' to F1 ', F1') occupied and in the folder 12 is not collecting, so are on the strands 109, 111 and 112, two identical successive issues of the above page numbers generated. It produces a total product with only 24 pages, but with double output.

The harp rollers 89; 93, in particular if they are executed undivided over the full length, can be rotationally driven in a development on its own, not shown drive motors. These are then z. B. with respect to their speed, u. U. also their location, run adjustable and are to take over current setpoints with the machine control or an electronic master in connection.

As in Fig. 17 shown, the folding structure 11 has at least two stacking rollers 101, 106 arranged one above the other; 102, 107; 103, 108, whose planes of symmetry S in each case in a common escape of the printing press straight through part of web 03a; 03b; 03c lie. In particular, the planes of symmetry S of the two stacked formers 101, 106 fall; 102, 107; 103, 108 substantially together with a median plane M of a two printed pages wide, straight running, only deflected in the vertical direction partial web 3a; 3b; 3c (3a ', 3b', 3c ', 3a ", 3b", 3c ", 3a"', 3b "', 3c'", etc.). The partial webs 3a; 3b; 3c etc. are in Fig. 17 from one below (to Fig. 18 ) reasoned and partially drawn to another part.

For the six printing pages wide printing press are according to Fig. 17 two vertically staggered groups of three formers 101, 102, 103 and 106, 107, 108 respectively. For four printing-wide presses, this can be two each, eight-sided wide printing presses each four funnels side by side. In each case an upper and a lower former 101, 106; 102, 107; 103, 108 are aligned in pairs in the above-mentioned manner to one another and to a respective center plane M. The three formers 101; 102; 103 and 106, respectively; 107; 108 of a group are transverse to the direction of the partial webs 03a; 03b; 03c offset from one another next to each other and arranged in an advantageous embodiment substantially at a same height. However, they may also be vertically offset from each other and / or have different vertical dimensions, but then z. B. in the horizontal plane at least partially overlap.

H. a group of a plurality of parallel casserole rolls harp rollers 89 offset from one another in the radial direction; 93, over which different tracks 03; 03 'or partial webs 03a; 03b; 03c; or 03a '; 03b '; 03c 'etc. are transferred from the superstructure 04 in the folding structure 11. Following the harp rollers 89; 93 they become a strand 109; 111; 112 or multiple strands 109; 111; 112 summarized. The later position of the partial web 03a; 03b; 03c; or 03a '; 03b '; 03c 'in strand 109; 111; 112 or whose printed pages in the intermediate and / or end product u. a. by the choice of a relative position to other, the Harfe 09 continuous partial webs 03a; 03b; 03c; or 03a '; 03b '; 03c 'already set in the harp 09. The harp rollers 89; 93 of a harp 09 are mutually vertically and / or horizontally offset and preferably stored as a unit in a common frame. In principle, for each of the vertically offset groups of formers 101; 102; 103 and 106, respectively; 107; 108 such a harp 09 may be provided.

To save height, have in an advantageous embodiment, as in Fig. 1 and Fig. 19 shown, the two superimposed, but in their plane of symmetry aligned folding hopper 101, 106; 102, 107; 103, 108 a common harp 09 on. For n full tracks to be printed 03; 03 '(eg n printing towers 01 of a section) of a respective maximum width b03 of m printed pages, the harp 09 advantageously comprises at least (n * m / 2) harp rollers 88; 89; 93, whose axes of rotation z. B. are substantially in a common plane, and which are preferably stored in a common frame. In the case of the present six pages width printing machine and z. B. two tracks 03; 03 '(or two printing towers 01) are at least six harp rollers 88; 89; 93 per harp 09 of Advantage.

In one embodiment of a section of the printing press with three printing towers 01 and three provided for the two-sided four-color printing tracks 03; 03 '; 03 ", at least nine harp rollers 88, 89, 93 are arranged per harp 09. In this section, a product with a total thickness of 72 pages can then be produced in the collecting operation.

In an advantageous embodiment of a printing machine with z. B. two sections of two printing towers 01 and a total of four provided for the two-sided four-color printing six printed pages wide webs 03; 03 '; 03 ", at least six harp rollers 88, 89, 93 are arranged per harp 09 of a section These six harp rollers 88, 89, 93 per section, here twelve, can be arranged in two structurally separate harps 09, eg over a common folding structure 11 or two folding structures 11, but also in a structurally common harp 09 eg in two alignments be In this printing press with two sections or a total of four printing towers 01 (four tracks 03, 03 ') is then in the collecting a product with a Total thickness of 96 pages can be generated.

In one embodiment of a printing press with z. B. two sections of two printing towers 01 and a total of four provided for the two-sided four-color printing six printed pages wide webs 03; 03 '; 03 ", at least six harp rollers 88, 89, 93 are arranged per harp 09 of a section These six harp rollers 88, 89, 93 per section, here twelve, can be arranged in two structurally separate harps 09, eg over a common folding structure 11 or two folding structures 11, but also in a structurally common harp 09 eg in two alignments be In this printing press with two sections or a total of four printing towers 01 (four tracks 03, 03 ') is then in the collecting a product with a Total thickness of 96 pages can be generated.

If only one folding structure 11 is provided for two sections, then the number of required harp rollers 89; 93 according to the configuration of the two sections. If the folding structure 11 is arranged between these two sections, then either all the harp rollers 89; 93 in an escape or to save height the harp rollers 89; 93 of each section each arranged in alignment and the alignment with each other in the radial direction offset horizontally. The harp rollers 89; 93 of the two escapes are here z. B. again arranged in a common frame.

Are, as in Fig. 1 indicated, although two folding assemblies 11 provided for the two sections, it may still be advantageous for at least one of the two harps 09 a number of harp rollers 89; 93, possibly in the two above-mentioned alignment, which would be required for both sections. Thus, there is an even greater degree of flexibility in product strength and composition. In a section printed sheets 03; 03 'can now be supplied to the other section if necessary for further processing of the harp 09 and vice versa.

According to Fig. 18 is at least one of the partial webs 03a; 03b, 03c, etc., which are in front of the upper former 101; 102; 103 arranged common harp 09 passes through, on the lower former 106; 107; 108 feasible or guided. Depending on the desired strength of the individual intermediates (booklets, books) are more or less of the partial webs 03a; 03b; 03c etc. on the upper and lower former 101; 102; 103 and 106, respectively; 107; 108 to convict. Depending on the production requirements so different strands 109; 111; 112; 113; 114; 116 on the respective lower and upper former 101; 102; 103 and 106, respectively; 107; 108 will be given. For example, the dashed in Fig. 17 partial webs shown as strand 113; 114; 116 on the respective lower former 106; 107; 108, and the solid on the respective top Former 101; 102; 103 led. This is, depending on where the "separation" in superimposed partial webs 03a; 03b; 03c etc. from the common Harp 09 is a flexible production of different strong intermediates (books, books) or end products with reduced effort possible. In Fig. 18 is a second escape from harp rollers 89; 93 is shown by dashed lines, by means of which, as described above, for example, partial webs 03a; 03b; 03c etc. can be recorded from another section.

In the case of multi-colored products, it is advantageous in the use of the described harp 09 folder assembly 11 in terms of flexibility, all printing units 02 or printing towers 01 or the paths of the web 03; 03 'with the same color. So z. B. the web 03; 03 'and / or partial web 03a; 03b; 03c etc. or the printing unit 13 for a colored cover sheet flexibly selectable and the strength of the intermediates variable.

The aforementioned folding structure 11 with only one harp 09 for two superposed formers 101; 102; 103; 106; 107; 108 is also suitable for other printing machines with different cylinder widths and cylinder circumferences. Such, from two stacked formers 101; 102; 103; 106; 107; 108 and a common harp 09 existing Falzoberbau 11 may also be arranged on a third former with its own harp 09. The described folding structure 11 with a plurality of vertically offset formers 101; 102; 103; 106; 107; 108 assigned harp 09 is also on three superposed formers 101; 102; 103; 106; 107; 108 well applicable.

Outside pages, for example, of an outer book can thus be assigned to a specific web guide and / or a specific printing tower / printing unit.

Through the multiple formers 101; 102; 103; 106; 107; 108 associated harp 09 it is possible, the superimposed partial webs 03a; 03b; 03c etc. depending on the desired product to flexibly process books of different sizes, without the need for a great deal of additional, unnecessary dislocations of partial webs 03a; 03b; 03c etc. would be required. So z. B. of four superimposed Partial webs 03a; 03b; 03c etc. in one case, three tracks on one and one on the other former 101; 102; 103; 106; 107; 108 are guided, while another time each two partial webs 03a; 03b; 03c etc. summarized on a former 101; 102; 103; 106; 107; 108 are guided. It is particularly advantageous that adjacent strands 109; 111; 112; 113; 114; 116 different degrees, as in Fig. 17 represented, can be summarized.

The formers 101; 102; 103; 106; 107; 108 in each case upstream Zug 117 and funnel inlet rollers 118 have in an advantageous embodiment as well as provided in the folding structure 11 draw rollers 121 ( Fig. 19 ) each have their own drive motors 119. In Fig. 19 is the draw roller 117 for the lower group of the formers 106; 107; 108 not visible. The respective drive motor 119 of the draw rollers 121 is in Fig. 19 merely represented by filling of the relevant draw roller 121. Each of the formers 101; 102; 103; 106; 107; 108, at least one such driven draw roller 121 is arranged downstream in an advantageous embodiment, which with pressure rollers or a pressure roller on the strand 109; 111; 112; 113; 114; 116 cooperates. In addition, the folding structure 11 preferably has non-driven guide rollers 122, via which the one printing side wide strands 109; 111; 112; 113; 114; 116 can be performed.

Particularly advantageous, for. B. with regard to the compliance / adjustment of longitudinal registers, also has the folder 12 at least one own, of the printing units 02 mechanically independent drive motor 120. While the drive motors 119 of the tractor inlet rollers 117; 118; 121 of the folding structure 11 and / or driven tension rollers 81 of the superstructure 04 only have to be controlled in terms of speed (with regard to an angular position), the drive motor 120 is designed to be adjustable or regulated with respect to its angular position on the folding apparatus 12 in an advantageous embodiment.

Thus, it is possible in an embodiment, the mechanically independent of each other driven printing units 02 and the folding apparatus 12 (or their drive motors 61, 120) to specify an angular position with respect to a virtual electronic master axis. In another embodiment, for. B. determines the angular position of the folder 12 (or its drive motor 120) and based on this, the relative angular position of the printing units 02 and 13 printing units specified for this. The z. B. only with respect to their speed controlled drive motors 80; 119 of the driven rollers 81; 117; 118 receive their speed specification, for example, from the machine control.
