Web guides of a web over turning devices on funnel structures.

In a first embodiment ( Fig. 1 ), a printing press 01 has a group of several, in particular at least two, adjacent printing units 02. The printing units 02 are formed here, for example, as printing towers 02 with a substantially vertical web guide and preferably have at least eight pressure points, z. B. four double pressure points on. In Fig. 1 there are three printing units 02 (dashed lines: optional four), through which one or more webs 03, z. B. paper webs 03, short webs 03 one or two sides printed. The printing units 02 have at least printing cylinder 04 designed as a forme cylinder 04. In the present case of offset printing units, each printing cylinder 04 is assigned a printing cylinder 06 designed as a transfer cylinder 06. In Fig. 1 are most printing cylinders 04; 06 covered by the web 03 and therefore shown by dashed lines. The printing units 02 of the printing machine 01 are arranged in alignment along a machine center plane M, which perpendicular to the axes of rotation of the printing cylinder 04; 06 stands. Preferably, the printing units 02 are formed as printing units 02 with a substantially vertical web run. This should possibly also include printing units 02, which comprise two stacked satellite printing units (9 or 10 printing units).

The respective webs 03 pass through the printing units 02, for example, substantially vertically, are after leaving the same z. B. deflected into the horizontal and are - for example via a roller group 08 of superposed in a frame guide rollers - in a transport direction T1 along the machine center plane M in a deflection 07, z. B. referred to as a turning device 07 or as a turning tower 07 or turning table 07, out. The turning device 07 closes in the transport direction T1 viewed in the embodiment according to Fig. 1 to the printing units 02, but can also, as in Fig. 6 set forth, arranged directly above a printing unit 02, z. B. on this, be.

In the presence of a printing press 01 with a plurality of webs 03 or a plurality of printing units 02, a register device, which is not described here, can be provided on the web path between printing unit 02 and turning device 07 or also after the turning device 07. This register device is designed to change a relative path length between the individual webs 03 and thus to adapt the position of the longitudinal register of the individual webs 03 to one another.

The turning device 07 is designed to deflect the projected into the horizontal path of the coming of the printing unit 02 web 03 (viewed in plan view) to a new transport direction T2 by substantially 90 ° to the first transport direction T1, so that viewed in the horizontal plane the two transport directions T1 and T2 are substantially perpendicular to each other.

After turning, the webs 03 are fed to a hopper assembly 09 where, after having been longitudinally cut on their way from the printing unit 02 to the hopper assembly 09, they are longitudinally folded as partial webs and / or laid on top of each other as part webs cut in the folding back (see below). After passing through the z. B. at least two adjacent formers 14; 16 having funnel construction 09, the resulting strands z. B. a folding unit 12 for further processing fed.

However, before the webs 03 are fed to the hopper assembly 09, they must be longitudinally cut by means of a longitudinal cutting device 11 in folds or superimposing suitable or intended partial webs.

In principle, a longitudinal cutting device 11 for producing the partial webs could be provided as desired on the web path between printing unit 02 and hopper assembly 09. So this can be provided in unillustrated embodiment between the printing unit 02 and the turning device 07 (not shown) to cut the web 03 or webs 03 before entering the turning device 07 in the corresponding sub-webs. The disadvantage here, however, that in this case narrow partial webs on the turning device 07 and subsequent transport routes must be performed up to the funnel assembly 09. This complicates - especially in the case of very narrow partial webs as they represent single or double-sided partial webs and / or at high transport speeds - the handling of the sub-webs and their transport safety on the way to a downstream funnel assembly 09.

In order to avoid or minimize these disadvantages (turning and / or guiding narrow partial webs), the printing press 01 is now designed with a turning device 07 extending over the entire width of a web 03 to be printed at most and a longitudinal cutting device 11 arranged downstream of the turning device 07. In this way, still uncut webs 03 can be deflected in the turning device 07 and continue to be performed uncut until shortly before the inlet into the hopper assembly 09. This results in that, depending on the required page number and Farbigkeitsanforderung in most cases, the required webs 03, in particular also webs 03 with a width b03 an odd multiple of a printed page, can be turned uncut and the turning of "narrow webs" (eg. one or two-sided partial webs) can be avoided or at least reduced. In addition to the longitudinal cutting device 11, however, a further longitudinal cutting device (39) (not shown here) can be provided for enabling very specific funnel assignments (see, for example, FIGS Fig. 28 and 29 ).

The turning device 07 is provided with at least one guide element 13, z. B. a turning bar 13, formed, which has a usable length L13, which in projection on the incoming web 03 at least their maximum width b03 _max and / or maximum usable width b04; b06 of the imaging printing cylinder 04 and the transfer cylinder 06 corresponds. It is inclined substantially at 45 ° to the transport direction T1 of the incoming web 03 and / or to the machine center plane M. In the present case, it has a length L13, the projection of which on the incoming web 03 corresponds to at least four adjacent newspaper pages. The usable length L13 of the turning bar 13 corresponds to z. B. at least 1.4 times the in the printing machine 01 to be processed maximum width b03 _{max of} the web 03, ie here z. B. at least 1.4 times a four newspaper page wide web 03 or here at least 5.6 newspaper page widths.

Preferably, the turning device 07 has a number of, in particular, at least one of the maximum number of webs 03 to be guided through the printing press 01, of a number of such long turning bars 13.

The turning bars 13 are in an advantageous embodiment - in z. B. a frame of the turning device 07 - formed transversely or in particular longitudinally to the transport direction T1 of the incoming web 03 movable. Thus, in webs 03 of different widths b03 or in narrower (initial) webs 03 of different lateral orientation in the printing unit 02, the orientation of the former 14 resulting after turning can be achieved. 16 adjust. Due to the mobility of the turning bar (s) 13, the tracks 03 after the turn z. B. also optionally flush to the one or the other side of the hopper assembly 09 aligned.

The tracks 03 revolve in such a 90 ° angled arrangement of machine longitudinal direction m and hopper 09 an odd number of turning bars 13, in particular only a single to the transport direction T1 an incoming web 03 inclined turning bar 13. They do not rotate here two turning bars 13, as it when staggered webs 03 are required in machines for straight-ahead operation.

The longitudinal section on a section line S1 (eg main section line S1) between each two adjacent formers 14; 16 (s. Fig. 2 ) can due to the turn with the long turning bars 13 then, for example, immediately before running on the former 14; 16, z. B. on a funnel inlet roller 17 or an upstream, not shown further draw roller done. The hopper inlet roller 17 and / or the draw roller, not shown, are or are advantageously driven by at least one of the pressure units 02 mechanically independent drive motor 18.

The longitudinal cutting device 11, in addition to a responsible for the main cutting line S1 knife 19 also further, with the respective funnel tips of the former 14; 16 aligned blade 21 (shown in phantom) for the optional formation of further longitudinal sections, z. B. cut line S2, (eg, side cut lines S2). By means of this is z. B. a funnel-wide strand in two partial strands halved and through the respective former 14; 16 following each other feasible. At least the blades 21 are - if present - arranged advantageously movable in the direction transverse to the incoming web 03.

For handling variable web widths is preferably at least one of two adjacent formers 14; 16 of the funnel structure 09 arranged such movable that a distance a between the funnel nose and the funnel symmetry planes can be varied. In an advantageous embodiment, both formers 14; 16 across to Running direction of the incoming web 03 movable. This can be done by a separate drive, in an advantageous embodiment, however, by a common drive. In the latter case, for example, a mechanism, for. B. threaded spindle with two opposing threads, be provided by means of which the former 14; 16 are simultaneously moved toward each other or away from each other when actuated.

The formers 14; 16 each have an effective width b14 in their casserole area; b16 on which z. B. a width of two stationary newspaper pages or lying tabloid pages of a particular, to be printed in the printing press 01 print format. The two formers 14; 16 are thus formed in total with a width for four juxtaposed printed pages (standing newspaper pages or lying tabloid pages).

If the printing press 01 is to be suitable for processing variable product formats and / or web widths, then the former 14; 16 z. B. in each case an effective width b14; b16 on which z. B. a width of two stationary newspaper pages or lying tabloid pages corresponds to a maximum in the printing machine 01 print format. This width b14; b16 is either changeable as described below or the former 14; 16 arranged in overlapping suitable manner.

In this context, as mentioned above, the two adjacent formers 14; 16 with respect to the distance a of their funnel tips changeable, but at increased distances in projection on the width of the incoming web 03 no gap in the effective widths between the two Former 14; 16 is present, but effective for folding width of the two formers 14; 16 in projection on the incoming web width gap to the folding of the two partial webs 03.1; 03.2 is formed.

In order to enable the longitudinal folding of different printing formats and thus different partial web widths with the above-mentioned different distances a, as in FIG Fig. 2 indicated by an overlapping area, the former 14; 16 in an advantageous embodiment, at least on the adjacent side in its width b14; B16 formed changeable from the edge. For this purpose, for example, in the adjacent edge regions of the former 14; 16 movable (eg wegklappbare) or removable attachment elements provided, which in the case of a wide web 03 (and correspondingly wider sub-webs) in the operating position and in the case of a narrower web 03 (and correspondingly narrower sub-webs) are removed from the effective range. Such extensions thus widen the transport plane of the respective former 14; 16, ie the plane which is formed by the contact zones of the converging flanks with the web 03.

In a variant, not shown, the two formers 14; 16 are slightly offset in the vertical direction to each other, but aligned with their funnel tips in a vertical, transverse to the transport direction T2 level with each other. If necessary (narrow web 03 and corresponding narrow partial webs), they can be pushed over one another in their adjacent edge area without being obstructed structurally. However, the funnel noses are as mentioned above. to each other in flight, so that folded strands come to rest on each other.

Per former 14; 16, a pair of cooperating folding and / or tension rollers 22 is provided directly below the hopper nose, which the over the triangular-shaped former 14; 16 current tracks 03 to form a strand 24. In the illustrated arrangement of Falzaufbauten by 90 ° inclined to the machine center plane M extending the Rotrationsachsen the folding rollers 22 substantially parallel to the axes of rotation of the printing cylinder 04; 06 of the associated group of printing units 02. Preferably, as folding and / or Pull rollers 22 motor -je roll individually or per pair of rollers - mechanically independent of the printing units 02 driven by their own drive motors M.

The folding unit 12 has one or two folders 23, z. B. designed as a single or double folder on. The folding unit 12 may also have a plurality of single folders. In the figures, only a single folder 23 is shown in each case. The folder 23 has z. As a cutting cylinder 26, a transport cylinder 27, a jaw cylinder 28 and possibly a paddle wheel 29 on. Optionally, but especially for the formation of the folder 12 for semi-commercial products, it additionally has means for forming a second transverse fold. The folder 23 is advantageously rotationally driven by at least one drive motor 31 mechanically independent of the printing units 02. Preferably, the drive is effected by the drive motor 31 on the cutting cylinder 26 and from there via mechanical drive connection to the transport cylinder 27 and the jaw cylinder 28. The paddle wheel 29 is optionally mechanically driven independently thereof by a motor. However, it can also cutting, transport and jaw cylinders 26; 27; 28 each have their own drive motor 31.

Particularly advantageous is a design of a printing machine 01 with a "wide" turning device 07 described above and / or a downstream, at least the main cutting line S1-generating longitudinal cutting device 11 and / or optionally the distance-changing formers 14; 16, when a rotated by 90 ° with respect to the straight-ahead hopper assembly 09 is provided and, inter alia, part-width webs 03 and / or narrow, generated by longitudinal section of a web 03 partial webs 3.1; 3.2 (see Fig. 2 ) on the former 14; 16 are to lead.

This is the case, for example, for printing presses 01, which have one or more uncut webs 03 with a web width b03 which corresponds to an odd-numbered multiple n (with n> 1) of a print page width - ie transverse to Running direction or in the axial direction of the printing cylinder 04; 06 viewed with an odd number greater than 1 of printed pages, in particular with 3 or 5 vertical newspaper or lying tabloid pages, is printed or are. For further processing in the subsequent hopper assembly 09, at least one single-side partial web 3.2 is produced and further processed in such cases. The hopper assembly 09 and the former 14; In this case, 16 then have an even multiple o on the pressure side, but where o> n, here z. B. o = 4 and n = 3.

In Fig. 3a and 3b is a printing machine 01 shown, the printing units 02 are formed with a width to at least in an operating situation ( Fig. 3a ) to print a web 03a of a width b03a with three printed pages, especially newspaper pages in broadsheet format, side by side. For this purpose, the forme cylinder 04 carries on its circumference, for example, one or more printing plates, which side by side in total print images of three newspaper pages of a first format F1, z. B. first broadsheet format F1 wear. The turning bar 13 and the former 14; 16 are now positioned to each other such that a two printing sides side by side having 2/3-width partial web 03.1 centered on one of the former 14; 16, here the former 16, while the remaining one-side part of part web 03.2 is guided on the other former 14, that the outer edge is guided with the plane of symmetry or the funnel nose of the other former 14.

In another, in Fig. 3b mode shown is a web 03b a smaller width b03b passed through the printing unit 02 and is with two pages, especially newspaper pages in the broadsheet format, a z. B. other, larger, formats F2, z. B. second broadsheet format F2, printed side by side. For this purpose, the forme cylinder 04 carries on its circumference, for example, one or more printing plates, which side by side in total carry the printed images of two newspaper pages of the format F2. The turning bar 13 and the former 14; 16 are now positioned so that the two sides of the print side by side web 03.2 undivided centered on a the former 14; 16, here the former 16, is performed. The distance a2 is now greater than the distance a1 of the first operating situation.

For the printing machine 01 with an odd number of side by side on a web 03 to be printed print pages is thus an embodiment advantageous, the turner bar (s) 13 with their length L13 to a maximum width to be printed b03 _max and the funnel assembly 09 to a total width of a next greater straightness is designed. Ie. if the printing unit 02 is designed to print three printing pages next to one another, the funnel structure 09 receives two each two-sided-wide folding funnels 14; 16, in design of the printing unit 02 on a maximum of five printed pages next to each other is a funnel assembly 09 with a total of three two-sided wide folders 14; 16 side by side to provide (not shown), with seven printed pages four formers next to each other, etc.

That in connection with the first embodiment of a printing machine 01 according to Fig. 1 to 3 mentioned, in particular for forming the turning device 07 and / or for arranging and forming the longitudinal cutting device 11 and / or for aligning and forming the funnel structure 09 with the two at a distance from each other changeable formers 14; 16 can be transferred in advantageous embodiments individually or in combination according to the formation of the units mentioned in the following embodiments (turning device 07 and / or longitudinal cutting device 11 and / or funnel structure 09).

Fig. 5 and 6 show a second embodiment of a printing press 01, wherein in addition to the printing machine 01 of the first embodiment in addition to a first turning device 07.1 and formed as a first funnel group 09.1 funnel structure 09.1 a first longitudinal cutting device 11.1 another turning device 07.2 with associated longitudinal cutting device 11.2 and associated, another two formers 14th ; 16 comprehensive second hopper assembly 09.2 or second funnel group 09.2 are arranged. Overall, at least four formers 14; 16 arranged side by side in a common plane, although not necessarily formed in groups of two, but are arranged in pairs in units in an advantageous embodiment.

The two turning devices 07.1; 07.2 are both in the alignment of the machine center plane M, in particular adjacent to each other. In this way, from the printing units 02 coming tracks 03 on the two turning devices 07.1; 07.2 and thus to the total now four formers 14; Distribute 16 of the entire hopper assembly 09 (09.1; 09.2). There are now twice the number (four) of longitudinally folded strands 24 (FIG. Fig. 5 ) and in the downstream folding unit 12 merge. If the four strands 24 are combined to form a product in a folding apparatus 23, a product with four so-called books can be produced without being collected. In collective operation, ie there are printing cylinder revolution consecutively printed two different printed pages on the web 03, which are then cut and collected in sections in the folding unit 12, are about the four juxtaposed former 14; 16 and the subsequent folder 12 even produce products with eight books.

The embodiment of the printing press 01 according to Fig. 4 and 5 is in training if necessary, a third or even fourth pair of formers 14; 16 with associated third and fourth longitudinal cutting devices 11 and turning devices 07 expandable.

The execution with at least four, in particular even six or more in a common plane juxtaposed former 14; 16 according to the second and subsequent third embodiment are particularly advantageous for printing machines, which build low and yet should have a high number of producible books.

Fig. 6 and 7 show a third embodiment of a printing machine 01, wherein at least four, in particular at least six formers 14; 16 are arranged side by side in a common plane. These can in principle be used individually, as a group of four or as above, preferably in two or three groups of two or two or three groups of funnels 09.1; 09.2; 09.3 trained funnel structures 09.1; 09.2; 09.3, each with two formers 14; 16 be summarized. The formers 14; 16 are as in the first embodiment with respect to the transport direction T2 of the former 14; 16 incoming web 03 inclined by 90 ° to the machine center plane M, ie, the web 03 is led out laterally from the machine alignment formed by the printing units 02.

In the execution of the former 14; 16 in groups of two is the space between the funnel groups 09.1; 09.2; 09.3 in an advantageous embodiment so that sufficient space for access (eg., Via a staircase from the folding unit 12 ago) and for retraction of the webs 03 or strands 24 remains.

The tracks 03, which z. B. have a width b03 that are equivalent to one, two, three or four pages in broadsheet format (1, 2, 3 or 4 broadsheet equivalents), 90 ° turn on the turning bars 13 almost anywhere on the formers 14th ; 16 are placed.

Preferably, the folding unit 12 is below the funnel groups 09.1; 09.2; 09.3 and laterally, but parallel to the machine center plane M, ie laterally to the machine alignment formed by the printing units 02. Under the funnel structure 09 are thus also long-built folding units 12, as they represent, for example, double folders with two folders or folders with a device for forming a second Längsfalzes integrated into the machine hall.

Due to the arrangement of at least four, in particular at least six formers 14; 16 in a common plane is despite high number of formers 14; 16 requires only one operating level for the paper guide and hopper assembly 09 (09.1; 09.2; 09.3).

Especially in connection with printing units 02, which are constructed in a particularly compact manner, despite the presence of more than two formers 14; 16 (according to the second or third embodiment) total for the printing machine 01 a small height reached. Such compactly constructed printing units 02 are designed to be separable, for example, for better accessibility in the area of the pressure point or between the forme cylinder 04 and associated inking unit and can therefore be constructed more narrowly. In addition, in such printing units 02 further space can be saved by using them as printing units 02 for the waterless printing, d. H. without dampeners, are formed.

In an advantageous and in Fig. 6 illustrated embodiment of the third embodiment ( Fig. 6 and 7 ) are in contrast to the first and second embodiments, the turning means 07 not in series with the group of directly adjacent printing units 02 (FIG. Fig. 1 and 4 ), but in the longitudinal direction of the printing machine 01 viewed in the longitudinal section of the group of adjacent printing units 02 arranged. You can do this as in Fig. 6 be seen in plan view each directly above a printing unit 02 arranged on this or at a level above the printing units 02 also in the machine longitudinal direction m offset to the printing units 02nd

In the embodiment of the printing press 01 according to Fig. 1 or 4 are the formers 14; 16 viewed laterally and in the machine longitudinal direction m offset from the group of at least two adjacent printing units 02; dhz B. there are transverse to the machine center plane M considered no former 14; 16 next to the group of Printing units 02. In contrast, in the embodiment according to Fig. 6 the formers 14; 16 laterally offset from the group of at least two adjacent printing units 02, but viewed in the machine longitudinal direction m at the level of printing units 02 arranged in this group, ie former 14; 16 and printing units 02 are next to each other. However, it may also be advantageous to use a mixed mold, one or more of the former 14; 16 next to the group, and the other formers 14; 16 is additionally offset in the longitudinal direction of the machine to the group of printing units 02 is / are.

In particular for the case that for a printing machine 01 in the machine longitudinal direction m several sections, d. H. a plurality of groups of adjacent printing units 02 are provided, each with associated hopper assembly 09, the printing units 02 adjacent sections without interruption by a turning device 07 and / or by a funnel assembly 09 can connect directly. The printing towers can then all be placed at the same standard distance from each other. This results in a favorable standardization effect for the entire structure. B. reflected in the identity of many components used for the configuration formation.

In the execution according to Fig. 6 and 7 the entire paper guide on a single operating level above the printing units 02, in particular in the above-mentioned compact constructed printing units 02, take place, regardless of how many formers 14; 16 are needed. In a simple manner, this can also be more than six in this embodiment of the printing press 01. A high number of formers 14; 16 is possible without the height is increased - as z. B. in the application of funnels in balloon arrangement would be the case).

With this arrangement, a plurality of formers 14; 16 side by side in one plane only two operating levels are required - one for the (compact) printing units 02 and another for the paper web guides in the turning and funnel inlet area.

For the o. G. Processing Requirement Variable web widths may include certain or all pairs of formers 14; 16 as described in the first embodiment, be executed individually or in pairs in opposite directions movable. As a result, webs 03 with an odd number of divisions (eg three or five printed pages wide) with variable width b03 can also be turned uncut and until just before the corresponding former 14; 16 are performed.

The printing machines 01 from the three preceding embodiments ( Fig. 1 to 6 ) can in principle be designed for the production of newspaper or semi-commercial products. In the latter case, the information given on newspaper pages for widths is b03; b04 of webs 03 and printing cylinders 04; 06 as broadsheet equivalents. The relevant web 03 or the relevant printing cylinder 04 is then designed such that it or he b03 in terms of its or its width; b04 would be suitable for receiving the corresponding printed pages in broadsheet format or a corresponding width b03; b04. In this case, the "newspaper page" functions as a measure in the steps of newspaper page widths or lengths. The same applies to the above mentioned information concerning the tabloid format with "tabloid pages".

The newspaper printing or the appropriately trained printing machine 01 is z. B. by the saccharification of uncoated or coated paper with a coating weight of at most 10 g / m ² . The newspaper (web 03) guided in the newspaper printing by the printing unit 02 can advantageously be located in a grammage range of less than 50 g / m ² . The forme cylinder 04 of the printing unit 02 operated in newspaper printing has printing forms with only one newspaper page at its circumference. The printing unit 02, which is operated in newspaper printing, has a non-figurative inking unit for coloring the printing form (s), which is filled or operated with coldset inks. The coldset color is characterized by special auxiliaries (such as Wetting agents, waxes gel formers, mineral fillers), which allow drying of the printed web 03 by breaking the fold in the paper. This is done in particular by the special combination of coldset ink and the paper used.

In a simple embodiment of a printing machine 01 for the semicommercial area, z. For example, for the supplements or telephone book or for magazines lower quality requirements for paper and color brilliance, coldset colors are also used. However, in order to meet a required product variety, the form cylinder 04 z. B. for receiving a reaching over the entire length printing form and / or the folding unit 12 has additional units, for. B. means for a second longitudinal fold and / or a second transverse fold and / or a stapler and / or a Pflugfalz, as is otherwise customary, for example, only for the higher-grade semi-commercial or commercial sector. The forme cylinder 04 of the (semi) commercial operation operated printing unit 02 may advantageously have printing forms with in the axial and in the circumferential direction a plurality of printed pages. For example, an over the entire length reaching printing form on the forme cylinder 04 may, for. B. several -. B. in the circumferential direction four and in the longitudinal direction of the printing cylinder 04 have six printed pages in tabloid format. Again, uncoated or advantageously slightly coated paper with a coating weight of at most 10 g / m ² can be used.

In a more elaborate execution of a printing machine 01 for the semicommercial area, z. As for higher quality magazines, magazines or title or cover pages with increased quality requirements for paper and color brilliance, a dryer is additionally provided through which the now printed with heatset colors sheets 03 are passed before they are turned and folded. In the printing press 01 of the Fig. 1 and 4 is a dryer 32 only dashed and symbolically indicated on the web path between the printing units 02 and the turning device 07. Another feature of the high-grade semi-commercial printing, for example, that the webs 03 here as paper webs 03 coated paper with a coating weight of more than 10 g / m ² , z. B. at least 15 g / m ^{2 are} formed.

The printing unit 02, which is operated in the higher-grade semicommercial printing, has an inking unit (not shown in the figures) for coloring the printing form (s), which is filled or operated with heatset in at least one operating mode (heatset mode). The heatset color is characterized by special oils, such. As mineral oils, which evaporate when exposed to heat and thereby leave the printed web 03 dry. The mineral oils have, for example, a boiling range of 220 ° C to 320 ° C. You can have a color related weight fraction of about 25 to 40%. Since the paint does not have to knock off to dry it is also possible to print closed-pored paper surfaces.

For example, a folding unit 12 associated with the production of semi-commercial products has a transport cylinder 27 designed as a gripper cylinder. One of the printing machine 01 for the production of newspaper products associated folding unit 12 may, for. B. have a trained as a cylinder cylinder cylinder 27.
