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 present invention consist in particular in that a web-fed rotary printing press with a folder for high output, especially together with a triple wide printing machine, is created in safe operation.

Advantageously, a transport cylinder is designed with a large circumference in order to ensure accordingly large positioning movements (cutting, holding, folding) at high production speeds safely. On the other hand, the increased radius of curvature reduces the pronounced oblique cut edge of the cross-cut product, especially in the case of strong products.

In an advantageous embodiment, the folder on a cutting cylinder with four cutting blades in the circumferential direction, d. H. he has a 4-fold extent of a section length. Of great advantage - especially in connection with the o.g. Printing machines - the 4-fold cutting cylinder and / or the pressure element (eg pressure roller) interacts with a 7-piece transport cylinder. This is designed for executions of the folder with 4-piece cutting cylinder basically either as Punkturzylinder or as a gripper cylinder.

With the advantageous embodiment of the cutting cylinder with four knives arranged circumferentially one behind the other, a geometrically conditioned significantly reduced tilting movement of the knife in the groove strips is caused by comparison with a 2-fold cutting cylinder. The four cutting blades or four section lengths (signatures) on the circumference having cutting cylinder ("four-circumference cutting cylinder") allows the use of significantly stronger bearings, a larger pin thickness and / or a stronger construction of the cylinder body itself, which contributes to increasing the stability. It can hereby stronger products (more layers) are cut because a higher force can be applied. For smaller product thicknesses may be due to the twisting and / or Low deflection increase the cutting accuracy.

In another advantageous embodiment or a development o.g. The folding apparatus has a pressure element, in particular a pressure cylinder, which serves the point needles when needling a strand (or strand bundle) as an abutment. The use of the pressure element is i.V.m. a running as Punkturzylinder transport cylinder of particular advantage.

In an advantageous embodiment of the folder is designed to selectively in a collective mode - recording several product sections one above the other on the transport cylinder during more than one revolution before a delivery of these stacked layers to the following cylinder, in particular jaw cylinder takes place - and in non-collection mode - delivery of the product section to be operated during the first passage through the nip between the transport and jaw cylinders.

The above-mentioned embodiments of the folding apparatus are particularly advantageous in connection with high-page-number products to be produced. An advantageous printing press has printing units with a width of the printing cylinder for printing six juxtaposed newspaper pages and one of the o. g folders. The forme cylinder of the printing unit then has a length for carrying one or more printing forms with a total of six juxtaposed newspaper pages - e.g. in broadsheet format - on. The folder in this case, for example, a funnel structure with three transverse to the direction of the tracks arranged transversely juxtaposed former.

Similar advantages also apply to a printing machine in which a plurality, for example, six or more partial webs before the folder to be folded together to a fold. Furthermore, the embodiments are particularly advantageous for high-speed printing machines, ie high-speed printing units for paper speeds of, for example, 12 m / s and more.

In particular, there are also advantages in that production reliability is considerably increased in the case of triple-wide printing units in comparison to a double-width printing press 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 acts at least on a section length always a closed lateral surface with the forming or satellite cylinder 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-orbit (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, d. H. several i. d. R. non-driven Auflaufwalzen (also collectors or take-off rolls called) to pre-allocate. 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 too need to provide or additional pressure 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.

With the six-cylinder unit and the web guides in particular advantages are that a high variety of products can be achieved and in conjunction with the aforementioned drive situations while a flexible and accurate drive is possible.

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, only the components of the right-hand half of the figure have corresponding reference numerals, since the left-hand side corresponds to the right-hand 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 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, not designated rolls two distribution cylinders 63, which rotationally together by means of its own drive motor 64 are drivable. 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.

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. 11.

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 shown in this illustration via a pinion 71 on an associated drive wheel 79, in particular gear 79, driven. Each driven by an independent drive motor 61 drive train is in an advantageous embodiment, at least for themselves, possibly encapsulated in even smaller units (stichliiert shown in Fig. 11).

Since the offset when turning, shifting, falls, etc. only this part of the web 03a; 03b; 03c and is bound to their special web guide, in an advantageous embodiment, the required register device 08 at least one of the course of the 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, 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, 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 to apply to parallel turning bars 82 of FIG. In the case of the crossed or orthogonal to each other 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.

In an advantageous development, in the superstructure 04 of a three-wide printing machine per entire web 03 two such, with register and turning device 08; 07 or register and harp roller 93 together "spatially variable" devices arranged above or below each other.

The guides 84; 96 (FIGS. 13 and 14) of the mentioned exemplary 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 folding structure 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 Pages width 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.

In one embodiment of a printing press with z. B. two sections of three printing towers 01 and a total of six provided for the two-sided four-color four printing pages wide webs 03; 03 '; 03 "are arranged at least three turning devices 07 per section.

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 ", four turning devices 07 are arranged per section, for example, and in this printing machine with two sections or a total of four printing towers 01 (four webs 03, 03 '), a product with a total thickness of, for example, 96 pages is collected In addition to the offset of a partial web 03a, 03b, 03c by an integer multiple of its partial web width b03a, an operating mode is advantageous in which a partial web 03a, 03b, 03c is an odd multiple of half the partial web width b03a and / or funnel width (ie by the factor This can be achieved by means of long turning bars (not shown) reaching across the entire width of the printing machine or the width b03 of the entire web 03, but also advantageously by means of The reversible rods 82 are then arranged, for example, as shown in Fig. 15 so that the first by the partial web 03a; 03b; 03c entwined Wendesta length 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 shown in FIGS. 15 and 16 using the example of the six printing-side wide hopper arrangement on a two-side-wide partial 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 lying escape longitudinally cut and runs on the folding structure 11 and the harp 09, d. H. undivided and / or split harp roller 89 and / or "short" harp roller 93, to (Figure 16).

FIG. 16 is a schematic sectional view of FIG. 15 with harp rollers 89 shown by way of example differently. 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 printed on both sides in double-size and three-width printing units (eg four-color) 03; 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' 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 is a total product with z. B. only 24 pages, but produced 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 shown in FIG. 17, the folding structure 11 has at least two stacking hoppers 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 'and 3a ", respectively; 3b ";3c" and 3a "';3b"'; 3c ", etc.) The partial webs 3a, 3b, 3c, etc. are partially drawn through in Fig. 17 for reasons explained below (for Fig. 18), and are shown by dashed lines to another part.

For the six printing pages wide printing press 17 two vertically offset groups of three formers 101, 102, 103 and 106, 107, 108 are arranged according to FIG. 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 one 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, in an advantageous embodiment, as shown in FIGS. 1 and 19, the two superimposed but in their plane of symmetry aligned with each other formers 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, for example, 72 pages can then be produced in the collective 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 Falzaufbauten 11, but also in a structurally common harp 09 z., In two alignments may be arranged Printing machine with two sections or a total of four printing towers 01 (four tracks 03, 03 ') is then in the collective operation a product with a total strength of z. B. 96 pages 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 eg 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.

If, as indicated in FIG. 1, two folding structures 11 are provided for the two sections, it may nevertheless be advantageous for at least one of the two harps 09 to have 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 if necessary for further processing of the harp 09 of the be fed to other section and vice versa.

According to FIG. 18, 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 partial paths shown by dashed lines in FIG. 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, a second run of 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. One 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 shown in Fig. 17, can be summarized.

The formers 101; 102; 103; 106; 107; In each case, upstream tension hammers 117 and hopper inlet rollers 118, as well as tension rollers 121 (FIG. 19) provided in the hemming structure 11, each have their own drive motors 119. In Fig. 19, the tension roller 117 for the lower group of the former 106; 107; 108 not visible. The respective drive motor 119 of the draw rollers 121 is shown in FIG. 19 merely by filling the respective draw roller 121. Each of the formers 101; 102; 103; 106; 107; 108 is at least one such driven in an advantageous embodiment Zugwalze 121 downstream, 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 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.

• a book with four pages and a book with eight pages, or
• two books with six pages, or
• produce three books with four pages and more variations.

In collected production, the page numbers of the intermediate products then collected from two longitudinally folded sections are doubled.

For printing in tabloid format the respective page numbers have to 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 to each "lying" printed pages, wherein in the circumferential direction or direction of the web 03; 03 '; 03a; 03b; 03c is a section A; B; C has two lying print pages, the form cylinder 16 then z. B. has a scope corresponding to four horizontal printed pages in tabloid format. The number of printed pages in the longitudinal direction remains per web 03; 03 '; 03a; 03b; 03c and cylinder 16; 17; 18 or funnel width exist.

In a particularly advantageous embodiment of the triple-width printing press, the folder 12 with a transport cylinder 123, z. B. collecting and / or folding blade, executed, which has a circumference for receiving more than five circumferentially successively arranged section lengths and a corresponding number of holding devices 129.

However, the folder can also be up to six strands 109; 111; 112; 113; 114; 116 are supplied from different funnel groups, which are then processed into a product.

The transport cylinder 123 is designed with an above-mentioned large circumference, so that correspondingly large positioning movements (cutting, holding, folding) at high Safely ensure production speeds. On the other hand, the increased radius of curvature reduces the pronounced oblique cut edge of the cross-cut product, especially in the case of strong products.

The folding apparatus 12 has at least one inlet, here two inlets, for one or more strands 109; 111; 112; 113; 114; 116 on.

The strand 109; 111; 112; 113; 114; 116 passes through a train roller pair 124 for adjusting the voltage and strikes the transport cylinder 123 at the level of a cutting gap 126 between the transport cylinder 123 on the one hand and a cutting cylinder 127 'on the other. Instead of two entrances and two cutting gaps 126, one, three or more may also be provided. In an advantageous embodiment, in the area of the puncture needle penetration (in the case of a Punkturfalzapparates), d. H. at the location of the needling of the strand bundle immediately before the cutting gap 126 at least one pressure roller arranged as an abutment. This has, for example, circumferential, corresponding to the arrangement of the needles in the axial direction of grooves in which the puncturing needles can penetrate after passing through the strand bundle / the strand.

Cutting the strand 109; 111; 112; 113; 114; 116 or strand bundle takes place in the cutting gap 126 between the cutting and transport cylinder 127 ': 123 by at least one cutting blade 128 of the cutting cylinder 127', which cooperates, for example, with a corresponding, not shown cutting bar on the transport cylinder 123 as an abutment.

The folding apparatus 12 may, in an advantageous embodiment, have a device (not shown) for shortening the effective circumferential section length. In a first variant for this purpose, the transport cylinder 123 in the region of its circumference between two transport devices 129 not shown, optionally in the radial direction out of the peripheral surface of the transport cylinder out and back into movable Verdrängerleiste which upon exiting the peripheral surface effective shortening of Signature with respect to the scope or effective enlargement of the distance between two causes. In an alternative embodiment, for example, the transport cylinder 123 has on its circumference in a region which is covered by accommodated product sections, a recess or depression (eg a groove or groove), into which a received product section by a corresponding projection (eg Strip or noses) on the circumference of the cutting cylinder 127 can be pressed.

The location of the activated, i. in operative position device for shortening (interaction of roller and bar or extension of a displacement bar on the transport cylinder 123) takes place advantageously within a section length following the cutting gap 126 (viewed in the direction of rotation).

The circumference of the transport cylinder 123 corresponds to seven section lengths or seven lengths of the signature ("seven-field transport cylinder 123"). On the transport cylinder 11 in the circumferential direction in succession seven at equal intervals in the peripheral surface of the transport cylinder 123 recessed holding devices 129, z. B. Punkturleisten arranged 129 with retractable Punktumadeln (Punkturfalzapparat). The holding devices 129 can also be designed as a gripper 129 (gripper folder). Furthermore, seven cutting bars are arranged, which are preferably arranged in the direction of rotation each slightly (for example, 0.3 to 3 cm) to location of the nip (Greiferfalzapparat) or the Punkturdurchstich (Punkturfalapparat) spaced on the lateral surface of the transport cylinder 123. The circumference of the jaw cylinder 132 also preferably corresponds to more than five, in particular seven, section lengths or seven lengths of the signature.

The strand 109; 111; 112; 113; 114; 116 truncated signature (section length, eg length of a stationary printed page, especially newspaper page) is further promoted by the holding device 129 on the transport cylinder 123.

On the transport cylinder 123 further seven folding blades 130 are mounted, which are each extended on reaching a gap 131 (depending on the collection or normal operation each or every multiple times) between the transport cylinder 123 and a jaw cylinder 132 to the transported on the transport cylinder 123 signatures to the Hand over jaw cylinder 132 and fold. For this purpose, the Jaw cylinder 132 circumferentially evenly spaced z. B. as many jaws (not shown) on how the number of folding blades 130 and / or the holding devices 129 on the transport cylinder 123, in particular seven. The folded products are transferred from the jaw cylinder 132 to a paddle wheel 133 and from there to a delivery device 134, z. B. a conveyor belt 134 designed.

Preferably, the folding apparatus 12, or its transport cylinder 123 is designed so that it can be switched between a mode for a normal and a collective mode optionally. When collecting the transport cylinder 123 is the signature (product section) is not yet at the first passage of the gap 131 to the next cylinder 132 from, but takes in a further revolution with the same, the first round, z. B. the jaw cylinder 132 passed, the first signature bearing holding means 129 at least one more signature before the so-collected signatures are delivered together in the gap 131 to the jaw cylinder 132. In the mode of normal operation, the transport cylinder 123 transmits the signature each time the first passage of the gap 131 to the next cylinder 132. The transport cylinder 123 is preferably implemented in a convertible execution as Punkturzylinder 123, in particular with seven Punkturleisten 129 in the circumference.

Cutting 127 ', transport 123, jaw cylinder 132 and possibly paddle 133 are preferably driven by at least one drive motor (shown schematically in Fig. 19 drive motor 120) mechanically independent of printing units 03, superstructure 04 and folding structure 11. The drive is advantageously via a transmission, in particular a reduction gear, from the drive motor to one or more of the cylinder 123; 127 '; 132 of the folding apparatus 12th

In a non-illustrated embodiment of the drive motor via an unillustrated transmission (eg., Unmentioned pinion or drive wheels) on the Cutting cylinder 127 'driven. The latter is driven onto the transport cylinder 123 and from there to the jaw cylinder 132. From the jaw cylinder 132 is driven here via a belt drive 137 to the paddle wheel 133.

In a variant indicated only by dashed lines in FIG. 20, the drive motor, not shown for this case, is driven by a pinion 138 or drive wheel 138 (dashed) onto the transport cylinder 123. The latter is driven onto the cutting cylinder 127 'and the jaw cylinder 132. From the jaw cylinder 132, e.g. again driven via the belt drive 137 on the paddle wheel 133. In both cases described, the delivery device 134 preferably has its own, from the cylinders 123, 127 '; 132 and the paddle wheel 133 mechanically independent drive motor.

Cutting 127 ', transport 123 and jaw cylinder 132 may also be mechanically independent of each other and driven by the printing units by their own drive motors.

In another advantageous drive embodiment cutting 127 ', transport 123 and jaw cylinder 132 are driven by at least one common or alternatively by one of the printing units mechanically independent drive motor, while in a first variant paddle wheel 133 and delivery device 134 by a common drive motor mechanically independent from the cylinders 923; 127 '; 132 and the printing units and in a second variant are each driven in rotation by their own drive motors.

A possibly provided band system for guiding the product sections into and through the folding apparatus 12 can also be mechanically independent of the cylinders 123; 127 '; 132 be driven.

With the execution of the transport cylinder 123 with seven Abschnütslängen on the circumference it is from o.g. Possible reasons, twelve tracks 03 and the corresponding number of partial tracks 03a; 03b; 03c etc. (up to seventy-two paper layers), divided into up to six strands 109; 111; 112; 113; 114; 116 to lead to the folder 12. This can be by means of a folder 12 without collecting a product with z. B. a total of 144 pages, especially newspaper pages produce. If the folder 12 executed for the collective operation, so can be by means of six webs 03, the product of z. B. 144 pages or more tracks 03 even higher page numbers produce. For the latter product, the folder 12 is designed, for example, as a wheel rebate, or else the holding devices 129 and the jaws have to be designed to accommodate such a large number of layers.

It is advantageous in this case if, in the entry area, one pair of draw rollers 124 or several pairs of draw rollers 124 each have at least one own drive motor 139. As a result, in the input region of the folding apparatus 12 a plurality of strands 109; 111; 112; 113; 114; 116 are summarized.

In accordance with the invention, the folding apparatus 12 has a cutting cylinder 127 'with four cutting blades 128 in the circumferential direction (FIG. 20). The circumference of the cutting cylinder 127 'substantially corresponds to four section lengths of the product to be cut. With one revolution, four cuts are made through the four knives 128 arranged one behind the other in the circumferential direction. The four knives 128 can advantageously be spaced alternately 90 ° -δ and 90 ° + δ apart from one another in an equidistant arrangement, where δ represents a small angle (for example less than 2 °, in particular less than 1 °). In particular, the longer and the shorter should differ from the middle section length by about 1 to 5, in particular 1.5 to 3.5 mm, d. H. two consecutive sections differ in length by a total of 3 to 7 mm.

While the cutting force is possibly increased, a reduction in the wear of grooved rubber, pressure bars and / or knives is effected. By optimized diameter design of the cutting cylinder 127 ', a reduction of the excavation effect in the grooved rubber and the bending load of the knife 128 takes place

For example, two or more strands or strands 135 may be combined prior to entry into the cutting gap 126 via a roller or roller pair 125 - driven by a motor (as a pull group 125) or as a non-driven (guide roller). However, it is also possible to supply only one strand bundle 135 to the folding apparatus 12 and to guide it into the cutting gap 126. In Fig. 20 has been omitted for simplicity on the detailed presentation of the rest of the conveyor system (drive motor, driven train group, etc.) and the drive motor including drive train. The circumference corresponds to four (average) lengths of the tracks 03; 04 to be produced signatures. In one embodiment, the cutting blades 128 are not arranged equidistant on the circumference of the cutting cylinder 127 ', but it alternates an angular segment slightly larger than 90 ° and a slightly smaller 90 ° at the periphery.

For folders or folders 12 for higher page numbers and higher speeds is next to the centrifugal forces, the needling (puncture) or terminals (gripper) and the folding itself and the cutting process and cutting performance is a critical parameter. The cutting cylinder 127 'with four-circumference is therefore particularly advantageous in the above-described printing machine with three-width printing units 02 and / or arranged together with a seven-field transport cylinder 123 because of the possibility of cutting strands of large product thicknesses. However, the four-circumference design is also applicable to any web press and / or co-operative with multi-field (eg, five or seven) transfer cylinders of other formats to increase accuracy and / or product strength. The quadruple cutting cylinder 127 'leads to a smaller tilt of the cutting blade 128 when hitting a cutting bar on the transport cylinder and there possibly provided slot rubber, which also requires a lower cutting power (energy or force) than when double cutting cylinder. Grooving and dewatering of the knife into the grooved rubber takes place at a considerably smaller angle of inclination of the cutting knife 128. Both the bending and the pressing load of the cutting knife 128 are lower overall than with the double cutting cylinder.

With the arrangement of a fourfold cutting cylinder 127 ', a second double cutting cylinder on the circumference of the transport cylinder 123 can be dispensed with despite strong products.

Also shown in Fig. 21 is an advantageous embodiment of the folding apparatus 12 - as a supplement to the execution with quadruple cutting cylinder 127 'and / or 7-fold transport cylinder 123 or viewed individually - with a pressing device 143 shown.

The arrangement of a pressing element 143 allows for a better and trouble-free needling of the product sections to be accommodated by puncturing needles 144 (the holding device 129) of the transporting cylinder 123. In this case, the bending stress of the point needles 144 (in short, needles 144) is reduced and / or the risk of bursting and stripping of the product sections during the puncture is reduced. In principle, it is possible to perform the pressure cylinder 143 for this purpose in different ways. For example, the lateral surface corresponding to the axial position of the needles 144 in the circumferential direction (the needles 144 during unwinding receiving) have circumferential grooves or recesses. Also, the lateral surface instead or in addition to this compliant material -. As foam - have, which yields at the puncture of the needles 144 at the point concerned, the strand aufausadelnden 135 but otherwise supports.

In an advantageous embodiment, a one or more parts, clocked Andrückzylinder 143, z. B. with spring-loaded pressing elements 146, provided to the strand 135 or strand bundle 135 during the penetration and puncture by the needles 144 firmly against the transport cylinder 123 (collecting cylinder) to press and the paper no to give bursting leading alternative way. The pressure cylinder 143 or the pressing elements 146 has or show in an advantageous embodiment complementary to each other in mutual settlement of Andrück- and transport cylinder 143; 123 resulting pattern of the extended needles 144 on a group of recesses 147, in particular holes 147, for receiving the needles 144 on. In Fig. 22, the interaction of needles 144 and the holes 147 of the pressing members 146 is shown schematically. Over the length of the Andrückzylinders 143 can either be designed as a strip pressure element 146 with multiple holes 147 or it can be arranged in the axial direction next to each other several pressing element 146, each with one or more holes 147, wherein the group of holes 146 in all cases as above are arranged to be arranged complementary to the arrangement of the needles 144. The pressure cylinder 143 preferably has a circumference which corresponds to an integer multiple of a section length of the product section. If the circumference of a section length corresponds to a group of above-described, axially spaced holes 144 is provided in cross-section. In a two section lengths corresponding circumference two circumferentially equidistant spaced groups of holes 146 are provided.

The puncturing needles 144 are prior to the puncture z. B. extended completely out of the transport cylinder 123, so that no additional acceleration forces acting on a movement of the puncture strips 129 causing puncture cam. It can be used in cross-section reinforced puncturing needles 144 to increase the stability.

Advantageously-as shown in FIG. 20-the strand 135 or strand bundle runs onto the transport cylinder 123 before the beginning of the puncture by the needles 144. The application of the pressure element 146 preferably takes place after the strand 135 has run onto the transport cylinder 123 but before the beginning of the puncture by the needles 144 instead. The piercing and puncturing the puncturing needles 144 takes place against these pressing elements 146th

Preferably, a lifting of the pressing elements from the strand or from the paper strands takes place after completion of the needling. This is supported for example by the radially outwardly directed resilient mounting of the pressing elements.

As stated above, the pressing elements in an advantageous embodiment at the site of the puncture of the puncturing needles 144 holes 147 on. These are z. B. with a slightly larger diameter than the point needles 144 itself. The holes 147 are z. B. tapered from the rear, on the one hand not to hinder the relative tilting of the puncturing needles 144 during the passage and on the other hand still prevent the paper at the puncture needle puncture at bursting through a narrow hole 147.

In addition, scraper elements may be provided to aid in the stripping of the paper as the punctures ebb. This can be z. B. by modification in the construction of the spud strip 129 and their movement dergestalt be done so that instead of pivoting Punkturhalter as well as in Räderfalzwerken linearly moving point needles 144 are used. Thereby, the holes 147 in the cylinder body of the pressure-applying cylinder 143 for penetrating the needles 144 can be made small enough to effectively assist in stripping.

In principle, it is also possible to carry out the pressure cylinder 143 without specially spring-mounted pressure elements 146. Here, for example, the holes 147 may be arranged directly in the lateral surface of the Andrückzylinders 143. They are then again complementary to each other in mutual settlement of Andrück- and transport cylinder 143; 123 resulting pattern of the extended needles 144 arranged. The pressure cylinder 143 may be mounted resiliently in total against the transport cylinder 123, wherein a minimum torque by possibly existing looping and / or the pulse during penetration of the strand 135 are taken into account got to.
