But it can also be provided differently type of electrically or magnetically actuable actuating means.

For mounting an elevator 16; 17 in one of the sections A to F and AB to EF is the leading, z. B. bent at an acute angle end 24 of the elevator 16; 17 in the relevant opening 28; 38; 39; 41 introduced. The first or first rolling elements 53 assigned to this section A to F or AB to EF and, if provided, the second rolling elements 54 assigned to this section A to F or AB to EF are coupled to the cylinder 16; 17 or to be wound up, already hinged elevator 19; 21 hired. Are already one or more other elevators 19; 21 on the cylinder 16; 17 are arranged and are to remain there, then the first and / or second rolling elements 53, which concern this section A to F or AB to EF, will also be arranged; 54 to the respective elevator 19; 21 hired. When first and second rolling elements 53; 54 are provided, presses when rolling the cylinder 16; 17 with the rolling elements 53; 54, the second rolling element 54, the trailing bent end 26 of the elevator 19; 21 in rolling into the opening 28; 38; 39; 41. Is or only first rolling elements 53 are provided, it is pushed in through them. Preferably, in this case, the rolling elements 53 remain; 54 stationary, while the cylinder 16; 17 is rotated in a direction of production P. The or in a release position (open) located holding means for the sections A to F and AB to EF, z. B. one or more clamping pieces 29; 43, changes or change to its or their holding or clamping position (closed). After the holding means has changed from its release position to its holding position, all rolling elements 53; 54 of the respective section A to F and AB to EF from the cylinder 16; 17 or its elevator 19; 21 switched off.

In an advantageous embodiment, the cylinder 16; 17; 18 of the printing unit 02 driven so that the printing units 13 of the printing unit 02 are rotatably driven in each case at least by one of the other printing units 13 mechanically independent drive motor 61. 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, attachment 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, in addition to other, not designated rolls two distribution cylinder 66th on, 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 connected to the transfer cylinder 17. 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).

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 by an integer multiple of its partial path width b03a, an operation is advantageous, wherein a partial path 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 must be no 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 has been offset from its original position (shown unfilled) 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 'products or intermediates (also called books or books) with the following, depending on the occupancy of the forme cylinder 16 and the corresponding mode of operation of the folder 12 different number of pages produce: 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' occupied for the second web 03 ') and takes place in the folding apparatus 12 a Cross cutting and collecting, so are on the strands 109 and 111 respectively two different booklets each with 10 printed pages, and on 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.

Seen in the web running direction, the folding structure 11 at least in front of one of the superimposed groups of formers 101; 102; 103 and 106, respectively; 107; 108 the funnel inlet of the webs 03; 03 '; or partial webs 03a; 03b; 03c defining harp 09, ie a group of several parallel, offset in the radial direction casserole or Harfenwalzen 89; 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 their printed pages in the intermediate and / or end product is inter alia by the choice of a relative position to other, the harp 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 one Such 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, the number of harp rollers required is 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 the before 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 (booklets, books) or end products possible with reduced effort. 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, over 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 one embodiment, the mechanically independently 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.
