Printing unit and a web-fed rotary printing machine

The invention relates to a printing unit and a web-fed rotary printing press according to the preamble of claims 1, 2, 3, 4, 5 and 44, respectively.

DE 25 28 008 A1 shows a printing machine for a direct printing process with forme cylinders which can be equipped with six printing plates in the axial direction and with two printing plates in the circumferential direction, and with impression cylinders which can be occupied with three in the axial direction and with a printing felt in the circumferential direction. Both the side-by-side printing plates and the side-by-side printing felts are each offset in the circumferential direction.

DE 25 10 057 A1 also discloses a printing press with a direct printing process, the forme cylinder cooperating with an impression cylinder carrying six printing plates on its width and two on its circumference.

JP 56-021860 A discloses a printing group with a form, transfer and impression cylinder, each of the three cylinders being driven by its own drive motor.

DE 41 28 797 A1 discloses a triple-width web-fed rotary printing press with two folding formers arranged on two different levels one above the other.

From "Newspapers &Technology", December 2000, a printing press with six newspaper pages wide printing units is known. The printing units are designed as bridge printing units, the transfer cylinders with rubber blanket sleeves are occupied.

WO 01/70608 A1 discloses a turning bar arrangement, wherein two turning bars which are essentially part of the web width are each displaceably arranged on a carrier transversely to the direction of the incoming part web. A register roller is arranged laterally outside the side frame, the longitudinal axis of which runs essentially parallel to the side frame and which is also displaceable along a rail in a direction transverse to the direction of the incoming partial web.

From US 4671 501 A a folding structure is known, two folding formers being arranged one above the other, the webs being cut lengthwise after passing through idler rollers in front of a third funnel, the partial webs being rotated through 90 ° over a third funnel and then being combined into two strands can be fed to both stacked hoppers.

EP 10 72 551 A2 discloses a folding structure with two groups of former formers offset vertically from one another. Above each of the groups of hoppers is a harp, i.e. H. a group of collecting, take-off or also harp rollers is arranged, via which the relevant partial webs are fed to the assigned group of formers.

In WO 97/17200 A2, a folding structure is known, according to which cut partial webs which are offset transversely to one another are fed to different folding formers. The horizontally side by side hoppers are z. T. vertically staggered.

DE 44 19217 A1 shows a superstructure of a web-fed rotary printing press with a turning device, partial webs being offset by half a partial web width in order to guide them one above the other and to feed them to a common former. The invention has for its object to provide a printing unit and a web-fed rotary printing press.

The object is achieved by the features of claim 1, 2, 3, 4, 5 and 44, respectively.

The advantages that can be achieved with the invention are, in particular, that a simple, inexpensive and space-saving construction is made possible with a high degree of variability in the product or intermediate product.

In particular, there are also advantages in that, compared to a double-width printing press, with the same target thickness of a product that can be achieved, production reliability is considerably increased. If the number of printing units is retained, the output of the printing press or of each printing unit can be increased by 50%.

The number of reel changers (investment), the frequency of reel changes (production security) and the set-up time when drawing webs (cycle times) can be reduced compared to a double-wide 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 results in high precision in the color register and on the other hand results in a low-vibration design. Vibrations are also reduced by the advantageous arrangement, design and attachment of elevators on the cylinders. On the one hand, openings on the lateral surfaces are minimized in the circumferential direction. Furthermore, at least on the transfer cylinder, the openings can be arranged alternately offset in the circumferential direction such that at least on a section length always a closed surface with the form or Satellite cylinder works together. Thirdly, out-of-roundness and manufacturing costs are minimized by the fact that channels are provided which axially penetrate the bale over its entire effective length, but openings to the lateral surface only exist in the sections mentioned. In the channels z. B. optionally devices for fastening elevator ends and / or filler pieces used.

At least six devices for the axial positioning of printing forms are arranged in the axial direction in the channel or channels of the forme cylinders. These are e.g. B. designed as a form-fitting together with printing die cooperating register pins which are arranged axially movable manually or remotely within the channel.

The design of the printing units with associated pressing devices is advantageous with regard to a register-accurate or register-accurate, reproducible loading of the forme cylinders with printing formes. With these, elevators resting on the lateral surface of the cylinder can be fixed by at least one pressing element as needed, while one end of an elevator or several elevators is or are released for removal or for fitting.

The drive of the satellite cylinder (s), which is mechanically independent of the cylinder pairs, has particular advantages with regard to the possibility of variable operation. For example, set-up during production, e.g. B. a flying change of printing form or washing. Conversely, a path can be drawn in while other cylinders or pairs of cylinders are stationary or are undergoing a set-up program. It is also advantageous if rubber blankets with positive or negative promoting properties are present to operate the satellite cylinder with a surface speed that is different from 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 paper running direction. In an advantageous embodiment, two register devices are provided per printing tower (or eight printing points each) that can be moved transversely to the paper running direction to compensate for the running paths of the partial webs. In a further development, these can be structurally connected to turning sections that are each part of the width of the web. Subsequent guide elements, which are only assigned to partial webs, are also e.g. B. essentially only partially run. These designs enable low-vibration, and therefore precise, transport of the train. Web tension fluctuations caused by inertia of long, strong guide elements that are only driven by the partial web (s) (for example, load changes, changes in printing speed) can be effectively reduced.

With regard to reliable operation and a cost-saving design, it is also advantageous to provide the possibility of turning a partial web in the superstructure by an odd multiple of half a partial web. This eliminates the need to pull in and print partial webs with half a funnel width (e.g. a newspaper page).

In terms of cost and space-saving design, it is advantageous in one embodiment to have a so-called harp, that is, only one of two folding formers arranged one above the other. H. several i. d. As a rule, pre-driven idler rollers. Sheets from the harp can be transferred to the other former. Strands of variable thickness or number of partial webs can be fed from the same alignment of partial webs lying one above the other to the two vertically arranged folding formers.

In one embodiment, partial webs from one harp assigned to one funnel group can be loaded on the other funnel group and vice versa. In an advantageous Only one of two folding hoppers arranged one above the other is to be assigned a so-called harp, that is to say a plurality of usually unpowered run-on rollers (also called collecting or removal rollers). Sheets from the common harp can then be transferred to the other former. Strands of variable thickness or number of partial webs can be fed from the same alignment of partial webs lying one above the other to the two vertically arranged folding formers.

In an advantageous embodiment of a turning device, the partial web can only be displaced or offset by an odd multiple of half a partial web width. So it can be z. B. avoid with little effort to have to print very narrow webs or to provide additional printing units. The design of at least one of the turning bars, which can be moved transversely to the track, enables great variability.

The drive of rollers of the former structure and / or of the folder, which is mechanically independent of the printing units, is particularly advantageous with regard to good registration and variable operation.

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.

In the middle between the holding devices 43, 44 of each section AB; CD; EF, ie in the area between sections A and B or E and F, here between the fifth and sixth clamping element 43, can also ei n filling element 49 (FIG. 6d) can be arranged. The filling element 49 essentially has a cross section of the channel 36; 37 modeled cross section and at least one through-going opening 51 in the axial direction, through which an operating means for the actuating means 46; 47; 48 is feasible.

The adjusting means 46; 47; 48 is designed in the embodiment shown such that when actuated, the holding device 43, 44 of a section AB; CD; EF, ie all clamping pieces 43 of a section AB; CD; EF, are closed or released at the same time. The adjusting means 46; 47; 48 is shown "pulled" out of the cylinder 17 in FIG. 6a. In the channel 36 (with two openings 38; 39) an adjusting means 46; 47 extends in each case at the end over at least the corresponding length of the section AB; EF. That of the middle opening Adjusting means 48 assigned to 41 also extends over at least the corresponding length of the assigned section CD, but it can also extend at least on one side to the end face of cylinder 17 if it is advantageous for the supply of operating resources (FIG. 6a). The adjusting means 46; 47; 48 are each axially running in the channel 36; 37 and can be actuated with pressure medium reversibly deformable hollow body 46; 47; 48, e.g. B. as a hose 46; 47; 48, executed. This hose 46; 47; 48 is shown in FIG. 6c with the clamping pieces 43 acting together in the channel 36; 37 arranged that it counteracts the self-locking spring elements 44, 44 closing spring elements 44 when actuated. It is passed through the areas of filler elements 49 to be passed through this or its opening 51 (FIG. 6d).

In another version of the channels 36; 37, these can also not be continuous over the entire length. For example, in the area of each section AB; CD; EF each have a channel 36; 37, if necessary with a corresponding holding device, is provided, the channel 37 of the middle elevator 21 being offset by 180 ° with respect to the two outer ones. This is only indicated schematically in FIG. 6e. In a printing unit 02 or cylinders 16; 17 advantageous embodiment is at least two cylinders 16; 17, in particular two forme cylinders 16, at least one of the printing towers 01 each have a device 52 for pressing an elevator 19; 21 to a cylinder 16; 17, in particular a printing form 19 on the forme cylinder 16, (hereinafter referred to as pressing device 52). This is e.g. B. advantageous if in two corresponding printing units 13 a fast, z. B. flying plate change should be made. In particular, it is advantageous for a quick, safe and exact product change if such a pressing device 52 is assigned to all forme cylinders 16 of a printing tower 01. A corresponding pressing device 52 has one or more pressing elements 53; 54, e.g. B. strips, plunger or rolling elements 53; 54, on which one or more elevators 19; 21 is or are adjustable. In this way, controlled and guided retraction or tensioning and / or detachment or removal of the elevator 19; 21 allows. This also makes it possible to have an end 24; 26 of the elevator 19; 21 in the corresponding channel 27; 36; 37 or the opening 28; 38; 39; 41 to move in or a released end 24; 26 or the partially released elevator 19; 21 in a desired Hold down location. The pressing device 52 extends along the cylinder 16; 17 at least in the entire area of sections A to F, ie in the area of the bale effective for printing.

The embodiment of the pressing device 52 described in FIG. 7 is particularly advantageous also in connection with the embodiment described in FIG. 5 for the common adjusting means 32 which extends over all sections A to F. In this constellation, an individual or group-wise mounting, changing and / or removing is also possible for six printing formes 19 arranged next to one another on the forme cylinder 16, without an increased expenditure of actuating devices or operating means having to be carried out within the forme cylinder 16. This also considerably simplifies production, assembly and maintenance.

The pressing device 52 has sections A to F (with six elevators 19 arranged next to one another) or section AB; CD; EF (with three lifts 21 arranged side by side) at least one first pressing element 53, e.g. B. rolling element 53, on. In an advantageous embodiment according to FIG. 7, it has sections A to F or section AB; CD; EF a in the circumferential direction of the cylinder 16; 17 second pressing element 54, z. B. rolling element 54 on. In the case of the forme cylinder 16, only central sections B, C and D and the rolling elements 53; 54 shown. For each section A to F or AB to EF there is a first rolling element 53 or a group of first rolling elements 53 arranged next to one another in the axial direction and z. B. a second rolling element 54 or a group of second rolling elements 54 arranged side by side in the axial direction. In the example, a first rolling element 53 and a group of three second rolling elements 54 are shown for each section A to F or AB to EF. With regard to the risk of possible canting and possibly incorrect axial alignment, the arrangement of groups of at least two rolling elements 53; 54. A single rolling element 53; 54 for a section A to F or AB to EF is, for example, as a roller 53 which extends in the longitudinal direction almost over the length of the section A to F or AB to EF; 54 executed, a rolling element 53; 54 of a group, however, z. B. only as the highest having a fraction of the length of the section A to F or AB to EF roller 53; 54th

The roller elements 53; 54 and, if provided, the rolling elements 53; 54 are basically movable independently of one another on, for example, a traverse 56 (or a plurality of traverses 56). The only first rolling element 53 or the group of first rolling elements 53 of each section A to F or AB to EF and, if provided, the only second rolling element 54 or the group of second rolling elements 54 of each section A to F or AB to EF are independent of each other by their own control means 57; 58 actuable. This adjusting means 57; 58 are, for example, as reversibly deformable hollow bodies 57; 58, in particular as a hose 57; 58 executed. However, different types of electrically or magnetically actuable actuating means can also be provided. To open an elevator 16; 17 in one of the sections A to F or AB to EF the leading, z. B. acute-angled end 24 of the elevator 16; 17 into 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 attached to the cylinder 16; 17 or to the already mounted elevator 19; 21 employed. Are one or more further elevators 19; 21 on the cylinder 16; 17 and should remain there, the first and / or second rolling elements 53; 54 to the respective elevator 19; 21 employed. If 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 when rolling over into the opening 28; 38; 39; 41. If only first rolling elements 53 are or are provided, they are pressed into them. The rolling elements 53; 54 stationary, while the cylinder 16; 17 is rotated in a production direction P. The one or more previously in a release position (open) holding means for sections A to F or AB to EF, z. B. one or more clamping pieces 29; 43, changes or change into his or her 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 relevant section A to F or AB to EF of the cylinder 16; 17 or its elevator 19; 21 turned off.

When bracing an elevator 19; 21 a distinction must be made as to whether one or more other elevators 19; 21 on the cylinder 16; 17 should remain. In this case, at least one of the elevators 19; 21 assigned rolling elements 53; 54 in the region of its trailing end 26 or near the opening 28; 38; 39; 41 to be employed or employed. The elevator 19; 21 assigned rolling element 53; 54 can remain parked. The holding means for sections A to F or AB to EF is opened. The trailing end 26 of the elevator 19; 21 is due to the internal stress from the channel 27; 36; 37 removed, while the elevators 19; 21 through the rolling elements 53; 54 are held down. The holding means is closed again. If the pressing device 52 has first and second rolling elements 53; 54, the elevators 19; 21 advantageously held down by at least the second rolling elements 54. When the elevator 19; 21 is at least the second rolling element 54 turned off so that the end 26 out of the channel 27; 36; 37 can escape, and the first rolling element 53 is turned on, so that the elevator 19; 21 still on the cylinder 16; 17 guided and held. The cylinder 16; 17, preferably against the production direction P, are rotated until the leading end 24 out of the channel 27; 36; 37 removed, and the elevator 19; 21 can be removed. Are bejm bracing the elevator 19; 21 no remaining elevators 19; 21 to be taken into account, the rolling elements 53; 54 of the elevator 19; 21 relevant sections A to F or AB to EF generally take any operating positions, preferably switched off, during the procedure.

It can thus on the lateral surface 30; 40 of the cylinder 16; 17 lying elevators 19; 21 by at least one pressure element 53; 54 can be fixed as required, while one end 24; 26 of an elevator 19; 21 or more elevators 19; 21 is or are released, d. H. is not pressed at this time. In an advantageous embodiment, the cylinders 16; 17; 18 of the printing unit 02 is driven in such a way that the printing units 13 of the printing unit 02 can each be rotatably driven by at least one drive motor 61 which is mechanically independent of the other printing units 13. In the case of the satellite printing unit 02, the satellite cylinder 18 can also be driven mechanically by a drive motor 61 independently of the assigned printing units 13. The drive motors 61 are preferably controlled as regards their angular position electric motors 61, e.g. B. as asynchronous motors, synchronous motors or DC motors. In an advantageous development, between the drive motor 61 and the cylinder 16 to be driven; 17; 18 or pair of cylinders 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). The individual drives contribute to the high flexibility and to avoid vibrations in the mechanical drive system, and thus also to the high quality in the product. In the following FIGS. 8 to 10, only the components on the right half of the figure have corresponding reference numerals, since the left side corresponds to the right side in mirror image. There are alternative configurations for any existing inking or dampening units 14; 20 indicated, which are to be transferred alternately to each other.

In Fig. 8, all nine cylinders 16; 17; 18 each have their own drive motor 61, which each z. B. via a gear 62 on the cylinder 16; 17; 18 drives. The inking unit 14 shown above has, in addition to further rollers, not designated, two distribution cylinders 63 which can be driven in rotation together by means of their own drive motor 64. The two distribution cylinders 63 can be axially moved and driven by a drive means, not shown, 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 further rollers (not designated), two distribution cylinders 66 which can be driven in rotation together by means of a separate drive motor 67. The two distribution cylinders 66 can be axially moved and driven by a drive means, not shown, to generate 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, via a mechanical coupling, e.g. B. via gears and / or belts, rotationally driven.

In contrast to Fig. 8, the two cylinders 16; 17 of each printing unit 13 in the embodiment according to FIG. 9 each driven by a common drive motor 61 on the transfer cylinder 17. The drive can be axial, e.g. B. via a gear 62, or via a drive pinion on a drive wheel of the transfer cylinder 17. The drive wheel of the transfer cylinder 17 can then be driven 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 a belt and is embodied encapsulated in a further development. For the drive of the dyeing and, if necessary, dampening unit 14; 20 via own drive motors 64; 67 or a cylinder 16; 17; 18 is basically the same as for Fig. 8.

In contrast to FIG. 9, the two cylinders 16; 17 of each printing unit 13 in the embodiment according to FIG. 10 each from a common drive motor 61, however driven on the forme cylinder 16. The drive can again axially, for. B. via a gear 62, or via a drive on a drive wheel of the forme cylinder 16 pinion. The drive wheel of the forme cylinder 16 can then be driven to a drive wheel of the transfer cylinder 17. The drive connection 68 can be designed as set out in FIG. 9. For the drive of the dyeing and, if necessary, dampening unit 14; 20 via own drive motors 64; 67 or a cylinder 16; 17; 18 is basically the same as that shown in FIG. 8.

In contrast to the embodiment indicated by dotted lines in FIG. 8 or 9 without its own rotary drive for the dyeing and / or dampening unit 14; 20, it is, however, advantageous in a further development to transfer from the transfer cylinder 17 to the dyeing and / or dampening unit 14; 20 to drive. A clear torque flow can thus be achieved and any tooth flank changes that otherwise occur can be avoided. An embodiment of such a drive train is shown schematically in FIG. 11.

The drive motor 61 drives via a pinion 71 on a drive wheel 72 which is connected to the forme cylinder 16 in a torsionally rigid manner and which in turn drives on a drive wheel 73 which is connected in a torsionally rigid manner to the transfer cylinder 17. The drive wheel 73 is either widened or a second drive wheel 74 is connected to the transfer cylinder 17. The widened or additional drive wheel 73; 74 drives via a drive wheel 77 arranged rotatably on a pin 76 of the forme cylinder 16 onto 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 gear wheels. In the event that the forme cylinder 16 is designed to be axially displaceable to adjust the axial position by, for example, ± ΔL, at least the pinion 71 and the drive wheels 72 to 74 are straight toothed. Between the drive motor 61 and the gear 62 consisting of pinion 71 and drive wheel 72, an encapsulated attachment gear 62 ', indicated by dashed lines, can additionally be arranged. The drive on the forme cylinder 16 can alternatively also take place axially on the pin 76, with an axial movement of the forme cylinder 16 possibly over a not shown, an axial relative movement between the forme cylinder 16 and the drive motor 61 receiving clutch. In this illustration, the satellite cylinder 18 is also driven via a pinion 71 on a drive wheel 79 assigned to it, in particular a gear 79. In an advantageous embodiment, each drive train driven by an independent drive motor 61 is encapsulated at least for itself, possibly in even smaller units (shown in broken lines in FIG. 11).

The described configurations of the printing unit 02 or the printing units 13 or their cylinders 16; 17; 18 or the drive enables low-vibration, precisely fitting printing of high quality with a low technical and spatial expenditure in relation to the achievable product strength. After printing the z. B. six printed pages wide web 03 this, possibly via unspecified guide elements and / or traction rollers, in the area of the superstructure 04 and z. B. guided by the longitudinal cutting devices 06 (Fig. 12). This z. B. a roller 81, for example a drive roller 81 driven by its own drive motor 80, with which pressure rollers can interact to avoid slippage. Longitudinal cutting device 06 and the pulling roller 81 can also be designed separately from one another, but another roller preferably interacts with the longitudinal cutting device 06 as a replacement. In this slitter 06, the web 03 is, for example, in several, z. B. three, partial web-wide webs 03a; 03b; 03c, short partial webs 03a; 03b; 03c (symbolized by center lines, lines 03a, 03b only indicated), cut longitudinally before these partial webs 03a; 03b; 03c subsequent guide elements, e.g. B. rolls of register devices 08, turning bars of turning devices 07, run-on rollers for the funnel inlet or pull rollers are supplied. In order to achieve a low-vibration web transport with regard to the web tension, individual, several or all non-driven or only by friction with the web 03a; 03b; 03c driven guide elements, which for guiding partial webs 03a; 03b; 03c are intended to be executed with a reduced length. So in addition to the length otherwise for z. B. six printed pages wide machines great required strength of the guide elements and thus significantly reduce the inertia. The risk of vibrations in the web tension, which otherwise exists especially when the speed changes, is effectively reduced, which in turn is reflected in the registration and thus in the quality of the print. The following explanations on the guide elements of reduced length, on the lateral changeability as well as on the assignment of a register roller to another guide element can be applied to a wide variety of printing presses, but are of particular advantage i. V. m. wide, e.g. B. six plate wide machines.

FIG. 12 shows a perspective oblique view of a first exemplary embodiment for at least part of the superstructure 04. The partial web 03b is shown as an example in FIG. 12 as partial web 03b turned outwards from the center. A second of the partial webs 03a; 03c could also be turned into another escape, for example, by means of a second turning device 07 of this type. A second turning device can e.g. B. lie above or below the first turning device 07.

As usual, the turning device 07 has two parallel or crossed turning bars 82 as the guide element 82, which are connected to the transport direction of the incoming partial web 03a; 03b; 03c form an angle of approximately 45 ° or 135 °, and by means of which an incoming web 03a; 03b; 03c laterally displaceable and / or fallable. The turning bars 82 advantageously have a length L82, the projection of which onto the transverse extent of the incoming partial web 03a; 03b; 03c slightly larger, e.g. B. 0% to 20% larger than the width of the incoming partial web 03a; 03b; 03c, ie the length L82 is approximately 1.4 to 1.7 times the width of the partial web. At least the length L82 is selected in such a way that its projection is less than or equal to twice the width of a two-sided width partial web 03a; 03b; 03c, ie the length L82 is at most 2.8 times the width of the partial web. In an advantageous development, the turning bars 82 each individually supported on supports 83 which run transversely 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 be moved from the desired web guide into the required position depending on the requirements. Under certain circumstances, both turning bars 82 can also be mounted on such a carrier 83.

Relocated, turned, transferred and / or fallen partial webs 03a; 03b; 03c experienced compared to other partial webs 03a; 03c i. d. Usually an offset in the running direction and are therefore corrected by means of a register device 08 in the longitudinal register. The register device 08 has at least one roller 86 which can be moved parallel to the running direction as the guide element 86. The roller 86 or a plurality of rollers 86 of the register device 08 advantageously have a length L86 which is insignificantly longer, for. B. 0% to 20% larger than the width of the incoming partial web 03a; 03b; 03c is. At least the length L86 is less than or equal to twice the width of a two-side-wide partial web 03a; 03b; 03c. In an advantageous development, the register device 08 is transverse to the direction of the incoming partial web 03a; 03b; 03c mounted on at least one guide 87 so that it can be moved. The now narrow register device 08 or its short rollers 86 can now be brought into the required position from the desired web guide as required.

In addition to cutting, turning and registering, if necessary, the partial web 03a; 03b; 03c in the superstructure 04 a. U. Be guided over other, not driven guide elements, such as guide rollers, not shown, before it is ultimately fed to an upstream of the folding structure 11 upstream or harp roller 88 of the so-called harp 09 (Fig. 1). For straight webs 03 or partial webs 03a; 03b; 03c is arranged in the superstructure 04 upstream of the harp roller 89, for example a register roller 91 which extends over the full web width b03 and can be changed in the transport direction and a deflection roller 92. In an advantageous embodiment, a length L88 of a guide roller and / or harp roller 88; 93 slightly larger, e.g. B. 0% to 20% larger than the width of the incoming partial web 03a; 03b; 03c. At least the length is L88; L93 (FIG. 13) less than or equal to twice the width of a two-side-wide partial web 03a; 03b; 03c. In the exemplary embodiment according to FIG. 12, the “short” harp roller 88 is realized as a section 88 of a harp roller 89 that is divided in this embodiment, but overall extends over a web 03 that is six printing pages wide. The sections 88 are rotatably supported here independently of one another.

However, instead of or in addition to a section 88, the “short” harp roller 88; 93 as guide element 88; 93 can also be designed as a harp roller 93 arranged individually on a frame. This can then either be fixed to the frame or else be arranged on a carrier 94 on a guide 96 transversely to the direction of the incoming partial web 03a; 03b; 03c.

Since the offset when turning, relocating, cambering, etc. only this partial web 03a; 03b; 03c relates and is bound to its special web guide, in an advantageous embodiment the required register device 08 can at least one run the partial web 03a; 03b; 03c determining guiding elements, such as. B. the turning device 07 or a turning bar 82 or the harp 09 or a "short" harp roller 93.

13, the "short" register device 08 is assigned, for example, to the "short" harp roller 93 and together with this on the guide 96 transversely to the direction of the incoming partial web 03b; 03c changeable.

14, the “short” register device 08 is assigned, for example, to one of the “short” turning bars 82 and, together with this, can be changed in position on the guide 84 transversely to the direction of the incoming partial web 03b. This arrangement is here for crossed Turning rods 82 shown, but to be applied to parallel turning rods 82 from FIG. 11. In the case of crossed or mutually orthogonal turning bars 82, there is at least one (here two) deflecting roller 97 with an axis of rotation extending perpendicular to the axis of rotation of roller 81.

In an advantageous further development, two such, with register and turning device 08; 07 or with register and harp roller 93, "short" devices which can be moved together are arranged above or below one another.

The guides 84; 96 (FIGS. 13 and 14) of the exemplary embodiments mentioned can be implemented in a wide variety of ways. For example, the guides 84; 96 can be designed as spindles with at least section threads, which are rotatably mounted on both sides and z. B. can be driven in rotation by a drive, not shown. The carrier 83; 94 can also be in the form of sliding blocks in rigid guides 84; 96, e.g. B. on profiles. A drive of the carrier 83; 94 also take place via a drivable spindle or in another way.

Variable crossovers or offsets of partial webs 03a; 03b; 03c possible over one or two part web widths (or multiples of half a part web width). The printed partial webs 03a; 03b; 03c into the alignment of one of several, here three, fold former 101 arranged transversely to the direction of travel; 102; 103 (Fig. 15) of the folding structure 11 brought. The transfer takes place, for example, in order to meet the requirement for different thicknesses of individual strands or ultimately intermediate or end products, while at the same time effective printing with the fullest possible web widths should take place.

For n full webs 03 to be printed; 03 '(e.g. n printing towers 01) of a respective one The maximum width b03 of m printed pages in an advantageous embodiment of the superstructure 04 has at least (n * (m 2 - 1)) turning devices 07. In the case of a six page wide printing press and e.g. B. three lanes 03; 03 '(or three printing towers 01) per section, six turning devices 07 per section are advantageous.

In one embodiment of a printing press with e.g. B. two sections of three printing towers 01 and a total of six four-page wide webs 03; 03 '; 03 ", at least three turning devices 07 are arranged per section.

In an advantageous embodiment of a printing press with z. B. two sections each of two printing towers 01 and a total of four webs 03; 03 '; 03 ", for example, four turning devices 07 are arranged per section. 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 then be produced in the collecting operation If a partial web 03a; 03b; 03c is offset by an integer multiple of its partial web width b03a, one mode of operation is advantageous, with a partial web 03a; 03b; 03c being an odd multiple of half a 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 turning bars (not shown) that extend over the entire width of the printing press or the width b03 of the entire web 03, but also advantageously by means of the position-changeable ones described above "Short" turning bars 82 take place. The turning bars 82 are then arranged, for example, as shown in FIG. 15, in such a way that the first of the partial web 03a; 03b; 03c wrapped turning bar 82 at least over an entire width of a subsequent former 101; 102; 103 is in alignment, while the second turning bar 82 has at least two adjacent halves of two subsequent folding former 101; 102; 103 escapes. The partial web 03a; offset by an odd multiple of half a funnel width b101 or partial web width b03a; 03b; 03c thus runs “between” the former formers 101; 102; 103. This is shown in FIGS. 15 and 16 using the example of the six-page-wide former arrangement on a two-sided part web 03a; 03b; 03c, but can also be transferred to machines of different widths No partial webs 03a; 03b; 03c or partial webs 03a; 03b; 03c of half a funnel width b101 need to be printed as such and fed through the machine, but a high variety in the product is still possible.

The partial web 03a; offset by an odd multiple of half a partial web width b03a; 03b; 03c is in front of the former 101; 102; 103 in a between the two aligned folding formers 101; 102; 103 lying escape cut lengthways and runs on the folding structure 11 or the harp 09, d. H. undivided and / or divided harp roller 89 and / or “short” harp roller 93, too (FIG. 16).

FIG. 16 is a schematic section of FIG. 15 with harp rollers 89; 93, the partial web 03c being displaced by one and a half partial web widths b03a from its original position (shown unfilled). It can, for example, if it has 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 with the partial webs 03a and 03b onto a former 100; 102 are performed. The two (intermediate) products then have e.g. B. at least one partial web 03c1; 03c2 of a partial web 03a; 03b; 03c on. In addition, partial webs 03a '; 03b '; 03c 'from others, e.g. B. in another printing unit 02 or another printing tower 01 printed webs 03 'onto one or more of the harp rollers 89; 93 accumulate. The partial webs 03a, 03a ', 03c1; 03b, 03b ', 03c2; 03c 'can now e.g. B. each to a strand 109; 111; 112 summarized a former 101; 102; 103 fed become. In the exemplary embodiment, two webs 03; each printed on both sides, in double-sized and triple-wide printing units (eg four-color), can thus be 03 'Produce products or intermediate products (also called booklets 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: With simple production, ie the forme cylinder 16 is different in the circumferential direction with two printing forms 19 Print pages A1, A2 to F1, F2 (or A1 ', A2' to F1 ', F2' for the second web 03 ') are occupied and in the folder 12 there is cross cutting and gathering, so there are two each on the strands 109 and 111 different booklets, each with 10 printed pages, and two different booklets, each with 4 printed pages, can be produced via strand 112. An overall product has e.g. B. 48 pages. If this printing press is operated in double production, ie the forme cylinder 16 is provided with two printing formes 19 with the same printing pages A1, A1; to F1, (or A1 ', A1' to F1 ', F1') and there is no collection in the folder 12, two identical successive booklets of the above page numbers can be generated via the strands 109, 111 and 112. A total product with only 24 pages but with double output is produced.

The harp rollers 89; 93, in particular if they are undivided over the full length, can be driven in rotation in a further development via own drive motors, not shown. These are then z. B. in terms of their speed, u. U. also their position, designed to be controllable and are connected to the machine control or an electronic master axis to take over current setpoints. As shown in FIG. 17, the fold structure 11 has at least two fold formers 101, 106; 102, 107; 103, 108, the planes of symmetry S of which are in a common alignment of a partial web 03a; 03b; 03c lie. In particular, the planes of symmetry S of the two stacking formers 101, 106; 102, 107; 103, 108 essentially together with a central plane M of a two printing pages wide, straight running, partial web 3a deflected only in the vertical direction; 3b; 3c (3a ';3b'; 3c 'or 3a ";3b"; 3c "or 3a'"; 3b '";3c'" etc.). The partial webs 3a; 3b; 3c etc. are partly drawn through in FIG. 17 for a reason explained below (relating to FIG. 18) and shown in broken lines for another part.

17, two groups of three formers 101, 102, 103 and 106, 107, 108, respectively, are arranged vertically offset from one another for the six printing pages wide printing machine. For four printing pages wide printing machines this can be two, for eight pages wide printing machines four funnels each other. An upper and a lower former 103, 106; 102, 107; 103, 108 are aligned in pairs in the above-mentioned manner to one another and to a central plane M. The three formers 101; 102; 103 and 106; 107; 108 of a group are transverse to the running direction of the partial webs 03a; 03b; 03c offset from one another and, in an advantageous embodiment, arranged essentially at the same height. However, if necessary, they can also be vertically offset from one another and / or have different vertical dimensions. B. at least partially overlap in the horizontal plane.

When viewed in the direction of web travel, the fold structure 11 has at least one of the groups of former formers 101; 102; 103 and 106; 107; 108 the funnel inlet of the webs 03; 03 '; or partial webs 03a; 03b; 03c defining harp 09, ie a group of a plurality of parallel roller or harp rollers 89; 93 on which different tracks 03; 03 'or partial webs 03a; 03b; 03c; or 03a '; 03b '; 03c 'etc. are transferred from the superstructure 04 into the folding structure 11. Following the harp rollers 89; 93 they become a strand 109; 111; 112 or more strands 109; 111; 112 summarized. The later location of the partial railway 03a; 03b; 03c; or 03a '; 03b '; 03c 'in strand 109; 111; 112 or its printed pages in the intermediate and / or end product is, among other things, chosen by the choice of a position relative to other partial webs 03a; 03b; 03c; or 03a '; 03b '; 03c 'already set in harp 09. The harp rollers 89; 93 of a harp 09 are offset vertically and / or horizontally from one another and are preferably mounted as a structural unit in a common frame. In principle, for each of the groups of folding formers 101; 102; 103 and 106; 107; 108 such a harp 09 can be provided.

In order to save overall height, in an advantageous embodiment, as shown in FIGS. 1 and 19, the two folding former 101, 106; 102, 107; 103, 108 a common harp 09. For n full webs 03 to be printed; 03 '(e.g. n printing towers 01 of a section) of a respective maximum width b03 of m printing pages, the harp 09 advantageously has at least (n ^* m / 2) harp rollers 88; 89; 93, whose axes of rotation z. B. lie essentially in a common plane, and which are preferably stored in a common frame. In the case of the present six pages wide printing machine and z. B. two lanes 03; 03 '(or two printing towers 01) are at least six harp rollers 88; 89; 93 per harp 09 is an advantage.

In one embodiment of a section of the printing press with three printing towers 01 and three webs 03; 03 '; 03 "there are at least nine harp rollers 88; 89; 93 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 press with z. B. two sections each of two printing towers 01 and a total of four webs 03; 03 '; 03 ", at least six harp rollers 88; 89; 93 per harp 09 are arranged in a section. These six harp rollers 88; 89; 93 per section, in this case twelve, can be arranged in two structurally separate harps 09, for example over a common folding structure 11 or two folding structures 11, but also in one structurally common harp 09 z. B. be arranged in two alignments. 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 then be produced in the collecting operation.

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

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

If, as indicated in FIG. 1, two fold assemblies 11 are provided for the two sections, it can nevertheless be advantageous to have a number of harp rollers 89; for at least one of the two harps 09; 93, if necessary in the two above alignments, which would be required for both sections. This provides an even greater degree of flexibility in terms of product strength and composition. In one section printed webs 03; 03 'can now be fed to the other section for further processing of the harp 09 and vice versa.

18, at least one of the partial webs 03a; 03b; 03c etc., which the the in front of the upper former 101; 102; 103 arranged common harp 09 passes through to the lower former 106; 107; 108 feasible or guided. Depending on the desired thickness of the individual intermediate products (booklets, books), more or less of the partial webs 03a; 03b; 03c etc. on the upper or lower former 101; 102; 103 and 106; 107; To convict 108. Depending on the production requirements, strands 109; 111; 112; 113; 114; 116 onto the respective lower and upper folding former 101; 102; 103 and 106; 107; 108 are given. For example, the partial webs shown in broken lines in FIG. 17 are shown as strand 113; 114; 116 onto the folding former 106; 107; 108, and the solid on the respective top former 101; 102; 103 led. Depending on where the “separation” in partial webs 03a; 03b; 03c etc. from the common harp 09 lies, flexible production of intermediate products of different strengths (booklets, books) or end products is possible with reduced effort. 18 shows a second line of harp rollers 89; 93 in broken lines, by means of which partial webs 03a; 03b; 03c etc. can be picked up from another section, as described above.

In the case of multi-colored products, when using the described folding structure 11 with a common harp 09, it is advantageous in terms of flexibility to use all the printing units 02 or printing towers 01 or the paths of the web 03; 03 'with the same color. So z. B. the train 03; 03 'and / or partial web 03a; 03b; 03c etc. or the printing unit 13 can be flexibly selected for a colored cover sheet and the thickness of the intermediate products can be varied.

The above-mentioned folding structure 11 with only one harp 09 for two folding former 101; 102; 103; 106; 107; 108 is for others too Suitable for printing presses with other cylinder widths and cylinder circumferences. Such a, consisting of two stacking formers 101; 102; 103; 106; 107; 108 and a common harp 09 existing folding superstructure 11 can also be arranged above a third former with its own harp 09. The folding structure 11 described with a plurality of vertically offset folding formers 101; 102; 103; 106; 107; 108 assigned harp 09 is also on three stacked former 101; 102; 103; 106; 107; 108 well applicable.

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

Due to the plurality of formers 101; 102; 103; 106; 107; 108 assigned harp 09, it is possible to lay the partial webs 03a; 03b; 03c etc., depending on the desired product, can be flexibly processed into books of different thicknesses without the need for additional, superfluous transfers 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 webs on one and one on the other former 101; 102; 103; 106; 107; 108 are guided, while another time two partial webs 03a; 03b; 03c etc. summarized on a former 101; 102; 103; 106; 107; 108 are performed. It is particularly advantageous that strands 109; 111; 112; 113; 114; 116 can be combined to different degrees, as shown in FIG. 17.

The formers 101; 102; 103; 106; 107; In an advantageous embodiment, 108 pull rollers 117 and funnel inlet rollers 118 arranged upstream each have their own drive motors 119 (FIG. 19) as are provided in the fold structure 11 (FIG. 19). In Fig. 19, the pull roller 117 for the lower group of the former 106; 107; 108 not visible. The respective drive motor 119 of the pull rollers 121 is shown in FIG. 19 only by filling the respective pull roller 121. Each of the formers 101; 102; 103; 106; 107; In an advantageous embodiment, at least one traction roller 121 driven in this way is arranged downstream, which is connected to the rollers 109 with pressure rollers or a pressure roller. 111; 112; 113; 114; 116 interacts. In addition, the folding structure 11 preferably has non-driven guide rollers 122, via which the strands 109; 111; 112; 113; 114; 116 can be performed.

Particularly advantageous, e.g. B. with regard to compliance with / setting of longitudinal registers, the folder 12 also has at least one drive motor 120 that is mechanically independent of the printing units 02. While the drive motors 119 of the pulling or funnel inlet rollers 117; 118; 121 of the folding structure 11 and / or driven drawing rollers 81 of the superstructure 04 need only be designed to be regulated in terms of speed (with respect to an angular position), the drive motor 120 on the folder 12 is advantageously designed to be adjustable or regulated with respect to its angular position.

Thus, in one embodiment it is possible to specify the printing units 02 and the folder 12 (or their drive motors 61; 120), which are driven mechanically independently of one another, with an angular position with regard 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, predetermines the relative angular position of the printing units 02 or printing units 13. The z. B. only with respect to their speed regulated drive motors 80; 119 of the driven rollers 81; 117; 118 receive their speed specification from the machine control, for example.

Due to the design of the web-fed rotary printing press with triple-wide and double-sized transfer and form cylinders and the corresponding design of the folding structure, it is possible to use a web, for example, in double production

- a twelve-page book, or

- a four-page book and an eight-page book, or - two books with six pages, or

- produce three books with four pages and other variations.

In batch production, the number of pages of the intermediate products then collected from two longitudinally folded sections each doubles.

For printing in tabloid format, the respective page numbers must be doubled. The dimensioning of the cylinder 16; 17; 18 and the groups of formers 101; 102; 103; 106; 107; 108 is to be applied accordingly to "lying" printing pages, whereby in the circumferential direction or running direction of the web 03; 03 ';03a;03b; 03c a section A; B; C has two lying printing pages, the forme cylinder 16 then, for example, the number of printed pages in the longitudinal direction remains per web 03; 03 ';03a;03b; 03c or cylinder 16; 17; 18 or funnel width.
