In the event that the wider of the two formers 09.1 is operated in this manner (eg, the first mode of operation), and that these are formed so as to be movable into one another in the upper region by their shaping, the smaller formwork former 09.2 is for this operating state (here the left) laterally from the path of the run on the wider former 09.1 web 02; 02 'or partial web 02.x; 02'.y move away or moved out (parking position). In other, for example, shown (second) mode of operation, the two formers 09 are moved together (or the narrower former 09.2 moved into operating position) and z. B. side by side of tracks 02; 02 'or partial webs 02.x; 02'.y same width, in particular half the nominal diameter of the hopper assembly 08 and / or a third nominal width of an upstream printing unit 01 and / or the effective width of the narrower former 09.2, run through or passable (see also Fig. 12 , right side). The wider former 09.1 is not effective in this case with its entire usable width.

The nominal diameter of the funnel structure 08 can, for. B. at least or substantially the sum of the juxtaposed in operating position formers 09.1; 09.2 correspond, so here significantly greater than twice the usable width 09.2 of the Schaleren Former 09.2.

The wider folding former 09.1 may preferably be arranged stationary with respect to a direction transversely to the web running direction, wherein in this case, for. B. protrudes in its upper region over the imaginary center plane of the hopper structure 08 to the other side out. The hopper syringe can be arranged at the same distance from the imaginary center plane, as the funnel tip of the narrower former 09.2 in the Operating position. The entire width of the two folded formers 09.1; 09.2 is then z. B. greater than two-thirds of a nominal diameter of the upstream printing unit (s) 01 or greater than twice the usable width of the smaller of the two formers 09.2.

In contrast to Beistelltrichtern greater width, the larger of the two formers 09.1 is in any mode within the flight of a web guide enabling nominal width of the funnel structure 08 and / or is preferably used for both, as well as for the other mode of operation, wherein z. B. in the case of the second mode of operation on its closer to the machine outside side has a not by (partial) webs covered area.

Preferably, in separate production (ie, simultaneous and separate production of retail or semi-commercial products in the heatset printing unit 01 / heatset printing units 01 and newspaper production in the coldset printing unit 01 / coldset printing units 01, the webs 02 printed on coldset printing units 01, or part webs 02.x. on the lower turning bars and the heatset webs 02 and partial webs 02'.y on the upper turning decks or turning bars.

In addition to the turning bars 16; 17, the turning tower 07 preferably still a group of vertically offset rollers 26, z. B. Rückstürz- and / or Bay Window rollers 26 have. These are advantageously located on the frame side 14 having the passage opening 13. These rollers 26 allow webs 02; 02 'or partial webs 02.x; 02'.y first pass through the turning tower 07, and by means of the rollers 26 at a desired height of the turning tower 07 this web 02; 02 'or partial web 02.x; 02'.y on the turning bar 16 in question; 17 to lead. Thus, a fan-like sorting of the individual webs 02; 02 'or partial webs 02.x; 02'.y take place in the desired position of the resulting strand bundle.

In Fig. 7a ), b) and c) are three advantageous embodiments for the formation of the support of the long turning bar 17 schematically, each in side view and in plan view shown. It is common to all of them that the end is not firmly clamped with respect to all spatial directions, but rather a movement in at least one of the spatial directions, in this case the direction transverse to the incoming web 02; 02 ', is free.

Fig. 7 a) shows a support of the turning bar 17 on a carriage 27 which is arranged longitudinally displaceably on a spindle 28. The spindle 28 can in this case at a Carrier 22 may be arranged, or advantageously take the place of the above-mentioned carrier 22. The turning bar 17 may be fixed or, as indicated, hingedly connected to the carriage 27.

In Fig. 7b) and c) the support is a linear guide, z. B. based on corresponding parts of a linear bearing. In this case, for example, the carrier 22 or attached to the carrier 22 bearing part on the frame-fixed part of a linear bearing 29, while on a connected to the end of the turning bar 17 carriage 31 of the corresponding bearing part is provided. Between carrier 22 and carriage 31 - as indicated - rolling elements may be provided in correspondingly shaped grooves. While in Fig. 7b) the frame-fixed bearing parts surround the bearing parts of the carriage 31, embrace in Fig. 7c) the bearing parts of the carriage 31 the frame fixed. The turning bar 17 may be fixed or, as indicated, hingedly connected to the carriage 31.

In principle, long turning bars 17 can be fixedly provided in one or more planes. It is advantageous, however, if the arrangement - at least in a minimum dimensions - is variably selectable. Therefore, in a first variable training at least one of the in Fig. 4 indicated carriage 23 formed in such a way that it can be either with a short or a long turning bar 16; 17 can be equipped. This optionally be equipped carriage 23 is then z. B. on the traverse 24 that plane provided, which corresponds to the other frame side 14 with a carrier 22. If instead of a short turning bar 16 now a long in the relevant level are used, the latter can be removed and the former used.

In an in Fig. 8 illustrated second variant is at least one of the short turning bars 16, in particular at least the short turning bars 16 in those planes in which long turning bars 17 'are to be used, designed extensible. For this purpose, in a variant, for example, a tapered pipe section of an extension piece 32 are inserted into the open end of the short turning bar 16 (or vice versa) to obtain a long turning bar 17. The connection of the opposite end of the extension piece 32 may then be supported as described. Advantageous may be a development in which the extension piece 32, for example, pivotally mounted on the carriage 27; 31 is arranged, wherein it pivoted away in the rest position from the working space, and when needed pivoted in and connected to the short turning bar 16 ( Fig. 9 ). In this case, it may be necessary to dispense with a nesting and instead on one of the web 02; 02 'facing away from a locking mechanism may be provided.

The extension piece 32 can also -. B from above - are suspended in a holder (eg with an opening in a pin 27, 31 arranged on the pin.

In an in Fig. 10 As shown, at least the turning bar 17 'of that plane (s) in which or also long turning bars 17' are to be used can be designed to be telescopically extensible. Of course, no paragraph should arise through the sections, so that in an advantageous embodiment, two interlocking turning bar bodies are each described by an envelope of a substantially same radius. For example, these are arranged in a circle lamellar structures having air outlet openings on the outer surfaces. These structures can then be pushed together or pulled out. In the case of the retracted state, the surfaces of the two bodies continued in the circumferential direction substantially to a circumference.

With the embodiment of the turning tower 07 set out, in particular in connection with the abovementioned embodiment, the forme cylinder 05 (for example with regard to possible printing forms) or printing units 01; 01 and / or the angular arrangement of the funnel structure 08 and / or the expression of the funnel structure 08 itself - a very variable distribution of whole tracks 02; 02 'in terms of number and width of different partial webs 02.x; 02'.y possible.

To the full train 02; 02 'in partial webs 02.x; To be able to cut 02'.y is 02 per lane; 02 'or per printing tower 01, a longitudinal cutting device 33 with at least one blade 34, in particular each with at least two blades 34, is provided. This knife 34, advantageously at least two blades 34 of the longitudinal cutting device 33, is or are transversely movable to the web running direction, d. H. controlled positionable, trained. This makes it possible to use the full web 02; 02 'as needed in different width stripes, d. H. Partial webs 02.x; 02'.y, to cut. At least several of these 34 blades of a longitudinal cutting device 33 are preferably independently positionable. Longitudinal cutting devices 33, which have a different number of blades 34, are preferably provided one above the other. For example, have two longitudinal cutting 34 only three knives 34, z. B. a middle fixedly positioned and movable on both sides blade 34, while at least one longitudinal cutting device has at least four blades 34 side by side, which are all preferably formed individually movable and positionable.

Fig. 11 to 14 show production / strand guide examples, which can be generated individually or optionally with the turning tower 07, in particular with the turning tower 07 having printing press. Here, this is done in each case on only one in a printing unit 01 printed web 02; 02 'shown. In principle, this can be a heatset or coldset web 02 '; 02 'be. Because in the FIGS. 11 to 14 the strand guide is in the foreground, the arrangement of the former 09 (09.1, 09.2) was only schematically and without the in connection with Fig. 3 illustrated conditions of a specific embodiment shown. The above detailed and based Fig. 3 However, embodiments shown are applicable to these examples, which is an example of the strand guides Fig. 11 and Fig. 14 when Strand run or mode a) and b) in each case for the former 09.1; 09.2 in Fig. 20 (For example, for at least one laterally, in particular two, for example, laterally movable in the opposite direction, the same or different large, slightly offset staggered formers, in principle the offset formers 09.1, 09.2 can be both laterally fixed here), Fig. 21 (for a smaller and a larger, in the upper area offset in height funnel, where, for example, the smaller funnel is moved laterally) and Fig. 22 (For a wider and a narrower, a recess having funnel) in each case again shown in front view.

In a mode according to Fig. 11 ( Fig. 20a . 21a . 22a ) becomes a web 02; 02 ', which has, for example, a width corresponding to six stationary newspaper pages, printed in a printing unit 01 and prior to emergence on turning bars 16; 17 of the turning tower 07 through the longitudinal cutting device 33 in two partial webs 02.1; 02'.1;02.2;02'.2 different width cut. The first sub-web 02.1; 02'.1 has, for example, one third (for example 22 "), and the second partial web 02.2; 02'.2 eg two thirds (for example 44") of the width of the full web 02; In the reversing tower 07, the wider sub-web 02.2, 02'.2 becomes the long turning bar 17, and the narrower sub-web 02.1, 02'.1 either also a long turning bar 17, but preferably one short turning bar 16, guided and deflected by the turning bars 16, 17 by 90 ° to the funnel structure 08. The narrow part web 02.1, 02'.1 here on the the strand run E or the web 02, 02 'printing unit 01 nearer Trichterflucht guided and deflected by a short turning bar 16 in a direction of a strand outlet A. The wider sub-web 02.2; 02'.2 is deflected uncut and after the turning tower 07 and before emergence on the hopper assembly 08 in a main cutting line, ie in one between the two juxtaposed Fatztrichtern 09 lying, cut longitudinally by means of a knife 36 another slitter 37. On the left side of Fig. 11 is schematically the emergence of the partial webs 02.1; 02'.1;02.2;02'.2 on the hopper assembly 08 in front view and the resulting folded strands shown. This mode of operation finds z. B. Application in conjunction with a coldset - especially with newspaper pages in broadsheet arrangement - printed web 02nd

In contrast to Fig. 11 shows Fig. 12 one to Fig. 11 similar operation, but the narrower sub-web 02.1; 02'.1 guided here on the Strangeinlauf E farther Trichterflucht and is deflected by a long turning bar 17. In the product, this is expressed by the fact that the narrower partial web 02.1; 02'.1 is now assigned to the strand of the further Falttrichters 09.

Fig. 13 shows a production / strand management example of a mode of operation, especially for a semi-commercial or "retail" production with a z. B. in heatset printed (and dried - thermal or UV) web 02 '. The web 02 'is here z. B. in more than two partial webs 02'.1;02'.2;02'.3;02'.4 cut, each having the highest 1/3 of the maximum web width b_max. These can all in an advantageous embodiment to only one funnel flight, z. B. on the lying with the short turning bars 16 in a same flighting former 09, are performed. It may be advantageous that a part of the partial webs 02'.1;02'.2;02'.3;02'.4 on the lower former 09 and a part of the partial webs 02'.1;02'.2;02'.3;02'.4 be performed on an overlying former 11 of the same escape. Alternatively, however, these can also be performed in part via short turning bars 16 on the folding hopper 09 lying in the same alignment with the short turning bars 16, and on the other folding hopper 09 over long turning bars 17.

Fig. 14 ( Fig. 20b . 21b . 22b ) shows a production / strand management example of the operation, wherein z. B. two half tracks or partial webs 02.1; 02'.1;02.2;02'.2, z. B. a same output path, respectively over long turning bars 16 on a same or in the same flight lying wider former 09.1; 11 are guided.

The particular for the operation, z. B. in the heatset, according to Fig. 13 printed web 02 'is preferably printed by a printing unit 01 with forme cylinders 05, which have a pressure over the entire effective width extending printing form, or at least two each extending over half the effective width printing forms. For the present dimension of a width, which corresponds to six adjacent newspaper pages in the broadsheet format, the printing forms in the former case are six-page wide and in the second case each three-page wide formed (based on a newspaper format). In this mode of operation carries the six-page wide or dreiseitenbreite printing form side by side z. B. not only a number of printed images of the same width, but may have side by side printed images of different widths. The different widths here not only mean a situation comparable to the application of panoramic pages, but in particular includes cases where the different widths are not all connected by a factor of 1 or 2. In another mode of operation, for. B. coldset, these forme cylinder 05 then z. B. with six one or three two-sided wide printing plates, or a combination thereof, be occupied.

Unspecified transfer cylinders may preferably have blankets which extend over the entire effective width and possibly over the full circumference of the transfer cylinder. In this case, for example, however, two such blankets may be arranged one behind the other in the circumferential direction. Preferably, this or these blankets are designed as metal blankets.

Preferably, the longitudinal cutting device 33 has more than two (here four, for example) blades 34, in particular transversely positionable blades 34. This makes it possible to create an in Fig. 13 to create a variability in the partial web width indicated by a double arrow for the partial web 02'.2.

An increase in the achievable with the turning tower 07 variability is the presence og rollers 26 on the side opposite the strand inlet E side of the turning bars 16; 17 ( Fig. 15 ). A printed web 02; 02 'or partial web 02.x produced by longitudinal section; 02'.y can then be passed from the side of the strand inlet E first through the turning tower 07 and reintroduced on the other side at a desired height as a position in the strand to be generated and the turning bar 16; 17 are led. This is particularly advantageous if, for example, a web having a higher quality printed and / or a different printing material 02 ', z. Example, a printed in heatset web 02 'and / or a higher paper quality and / or another base color having web 02', with webs 02 or partial webs 02.x different quality and / or other print quality (eg., Coldset) one or more mixed strands should or should be processed.

Fig. 15 a production / strand guiding example of a mixed product of coldset and heatset webs 02; 02 'or strands illustrated with several alternative possible ways, where tracks 02; 02 'or partial webs 02.x; 02'.y from both sides on the turning bars 16; 17 of the turning tower 07 feasible, and thus fan-like to a desired place (location) in the product can be brought. The feeding of the webs 02; 02 'to the turning tower 07, in particular to the longitudinal cutting means 33, but preferably takes place from one side. Thus, for example, a first web 02 '(here the uppermost) printed in the heatset upstream and dried and then cut into partial webs 02'.y. One or more further webs 02 is or are printed in coldset and also cut into partial webs 02.x. Should now be at different locations of superimposed partial webs 02.x; 02'.y be printed in the heatset partial web 02'.y be provided, so from a same track 02 'originating partial webs 02'.y be guided by the turning tower 07 and returned to the appropriate height again. The turning bars 16 to be occupied by the partial webs 02'.x to be inserted; 17 ("compartments") are then kept free by correspondingly downwardly or upwardly shifted occupancy with partial webs 02.x coming from the side of the strand entrance E (not shown but merely by dashed guides indicated.

In the in Fig. 15 illustrated embodiment, the turning tower 07 with twelve levels, ie twelve decks is formed, which a possible guidance of twelve partial webs 02.x; 02'.y, z. B. as mentioned above of four six-sided full tracks corresponds. This turning tower 07 can then be designed as a correspondingly high turning tower 07 or else of several stacked modules. In the illustrated advantageous embodiment, printing units 01, ie in each case at least one (in each case two) printing unit 01, are arranged on both sides of the turning tower 07. In an advantageous and in Fig. 15 dashed lines indicated execution the turning tower 07, the tracks 02; 02 'supplied only from one side, wherein the originating from the other side tracks 02; 02 'as shown under the turning tower 07 through or over the turning tower 07 are passed away, and wherein partial webs 02.x; 02.y guided in the above sense by the turning tower 07 and can be led back from there.

Fig. 16 shows an embodiment of the printing press with two in the web running direction successively arranged hopper assemblies 08; 08 'as exemplified in Fig. 1 shown, wherein in the web running direction second funnel structure 08 'z. B. has two levels, each with only one former 38. This former 38 may then preferably have a width corresponding to a "wider" former described above 09.1 and 11 respectively. The purpose of this is to apply accordingly. The turning tower 07 in this case has a group with a number of upper turning bars 16; 17 and a group with one, z. B. the first number corresponding, number of lower turning bars 16; 17 on. The partial webs 02.x guided onto the upper group; 02'.y are guided, for example, over the first funnel assembly 08 to the - preferably single-width - second funnel assembly 08 '. As a result, for example, produce different products simultaneously, with z. B. on one or more left printing units 01 of the printing press ( Fig. 1 ) a product, eg. B. a newspaper product, via a group, for. B. bottom group, of turner bars 16; 17 from the first Hopper structure 08 produced, and at the same time on one or more right pressure units 01 -. In heatset - via an upper group of turning bars 16; 17 is produced on the second hopper assembly 08 '.

The upper group of turning bars 16; 17 may have only short, cantilevered turning bars 16 in the case of a merely single width second hopper assembly 08 '.

In Fig. 17 and 18 schematically an advantageous embodiment of the turning tower 07 is shown for the case that the funnel structure 08 or funnel structures 08; 08 'not offset by 90 °, but is arranged in straight ahead in the machine alignment F or are. Fig. 17 shows an operating situation in which a partial trajectory 02.x; 02'.y by turning two parallel turning bars 16 is only offset laterally in their flight. For this purpose, two short turning bars 16 of the turning tower 07 can be used. In contrast, shows Fig. 18 two crossed long turning bars 17, over which, for example, a whole or at least half of the maximum width b_max corresponding (eg, three, four or more newspaper pages wide) web 02; 02 'or partial web 02.x; 02'.Y can be overturned - for example via a Bay Window guide on another roller 39. Not shown is a mode of operation with two parallel long turning bars 17, with which at least half but less than an entire of the maximum width b_max corresponding Track 02; 02 'or partial web 02.x; 02'.y can be offset laterally. For the storage and support of the short and / or long turning bars 16; 17 is the above-mentioned apply.

In mixed or hybrid production, ie when coldset webs 02 and heatset webs 02 'in a common product, in particular even already on a former 09; 11, an embodiment is advantageous for the preceding embodiments in which the nominal web width b (before printing, ie, for example, on the roll changer) of the heatset web 02 'and the coldset web is 0.5 to 2%, in particular 1% to 1.5%, the heatset web 02 'being the wider one. This means z. For example, for a "nominal" production width of 66 ", a nominal width b of the heatset web 02 'of, for example, 66" and a smaller nominal roll width of the coldset web 02 of about 65.66 "to 64.7", or conversely, the coldset web 02 (FIG. prior to printing) having a nominal width b of 66 "and the heatset web 02 having a nominal width b (before printing and drying) of 66.33" to 67.32 ", as well as for narrower web 02 productions 02 'or part widths (3/4, 1/2-wide, etc.) tracks 02, 02' accordingly.

Fig. 23 and Fig. 24 show variants for the printing machine with first and second printing units, in which case the superstructure, in particular the turning tower 07 on a above the coldset pressure units 01 (further or second printing units) provided frame is arranged. In this case, then not all second printing units (viewed in plan view) on the other side of the turning tower, but the machine is even more compact. In Fig. 23 are two first printing units 01 (Heatsetdruckeinheiten) arranged in the web path, z. B. superposed dryers 04 and two second printing units 01 (coldset pressure units) without dryer provided. In the execution according to Fig. 24 are three second printing units 01 (without dryer) and a first printing unit 01 provided with a dryer 04 in a web path. In Fig. 23 are two hopper assemblies 08; 08 ', each with a folder 15, in Fig. 24 a hopper assembly 08 with two folders 15 is provided, but this is also to be applied vice versa.
