Description

The invention relates to a printing machine system, in particular for newspaper and Semicommercialdruck, according to the preamble of claim 1.

By the DE 102 38 010 A1 For example, there is known a printing machine having both newspaper printing units and a printing unit for printing semicommercial products by means of which a folder is produced on a common, newspaper and commercial folder.

The WO 2004/024448 A1 discloses a printing machine having a plurality of printing units, at least one dryer and a folding apparatus, wherein printing units are arranged side by side with respect to the axial direction of their cylinders. A web path from the printing units to a three-hopper juxtaposed hopper assembly has a 90 ° bend projected into the horizontal.

In the WO 03/031182 A1 discloses a printing machine with a plurality of printing towers for the printing of newspaper products, wherein the printing towers are arranged in a direction perpendicular to the axial direction of their printing cylinder stationary machine flight, ie the printing machine is designed as a so-called. Line machine. The inlet direction of formers of a hopper assembly associated with straight running also run along or at least parallel to the machine alignment.

By the DE 40 12 396 A1 are two printing machine lines, each with a plurality of juxtaposed, successively traversed by a web printing units known, with additional devices of a printing press can be used by transferring the web into the other printing press.

In the US 19 72 506 A a printing machine with a plurality of juxtaposed printing units and a flush funnel structure is disclosed. From 90 ° to the first machine offset staggered printing units, multi-color printed partial webs can lead to the funnel structure of the first machine.

The DE 20 2005 010 058 U1 respectively. EP 16 83 634 A1 shows a printing press with two printing machine subsystems, wherein the printing machine subsystems are designed differently so that in these printing material webs with a different number of printed pages are printable.

In the publication "Handbuch der Printmedien"; Helmut Kipphan; Springer, 2000; S.357 and 358 are given examples of printing presses or presses with combined heatset / coldset machine lines.

The publication "Atlas of Newspaper and Illustration Printing"; Alexander Brown; Polygraph, 1960, presents on page 152 a printing machine with a four-plate wide printing unit and a double-width hopper assembly with downstream folder, which can be supplied from an envelope or insert machine with offset by 90 ° to the first machine printed single-sided webs in the folder of the former machine are.

Fig. 1 a) shows a schematic plan view of a printing press system, wherein in addition to one or more printing units 02 of a first type (or first printing unit 02) of a first printing machine 01 and one or more printing units 03 of a second type (eg second printing unit 03) of a second printing press 31 are provided. The first and second printing units 02; 03 are designed differently from each other in the manner described in more detail below.

However, special advantages in terms of product design arise when the both types of printing units 02; 03 - depending on the requirement - are different from each other.

The two types of printing units 02; 03 or printing machines 01; 31 now differ in the width and / or in the circumference of their imaging printing cylinder 04; 14, ie in the maximum effective for the printing length and / or in the circumference of the imaging printing cylinder 04; 14, z. B. forme cylinder 04; 14 (see below). Ie. they are designed with a length and / or a circumference, which a different number of printed pages of the same format, for. B. newspaper pages in broadsheet format, corresponds or a mutually different number of printed pages on the forme cylinder 04; 14 carries. For example, the printing unit 02; 03 of the one type printing group cylinder 04; 14 of a width of four printed pages, in particular four newspaper pages ("double width"), and - at least the forme cylinder 04 - with a circumference corresponding to the length of two printed pages ("double round"), in particular two newspaper pages ("double round"), be formed, ie in so-called "4/2" version, while the printing unit 03; 02 of the other type in 4 (length) / 1 (circumference of at least the forme cylinder 14; 04) execution, in 2/2 version ("single-width" and "double-round") or 6/2-type ("three-width" and " Doppeltrund ") is formed. In single-round design, one with the "single round" form cylinder 04; 14 cooperating printing cylinder 06; 16, z. B. transfer cylinder 06; 16 (see below) also be formed double round. In principle, the one printing press 01; 31 as one of the embodiments 2/1 ("single-width" and "single-round"), 2/2 ("single-width" and "double-round"), 4/1 ("double-wide" and "single-round"), 4/2 ("double-wide "and" double-round "), 6/1 (" triple-width "and" single-round "), 6/2 (" triple-width "and" double-round ") while the other printing machine 31; 01 is formed as one of the first different of the mentioned embodiments. It can also be a wider, z. B. double-width printing unit 02 single round (4/1 version), and the printing unit 03 of the second type single-width and double-round (2/2 version) be executed. Generally speaking, in an x / y design, the form cylinder carries 04; 14 of the relevant printing unit 02; 03 on its circumference in the longitudinal direction next to each other a number of x and in the circumferential direction a number of y printed images (or the number of printing plates, eg printing plates, each with a printed image) of the format in question, z. B. tabloid formats or newspaper formats, especially in the newspaper format in broadsheet format.

In the choice of the training of the printing press 01; 31 with respect to the distinction in scope - single-circumference or double-circumference design - can be a single-circumference design (eg 2/1, 4/1 or 6/1) advantages with regard to the to be changed during production change printing forms and / or in view of the infidelity in the product to be finished and / or a machine height. However, a double-circumference design (eg 2/2 4/2, 6/2) can offer advantages in terms of maximum product production in collective production. With regard to the distinction in the longitudinally juxtaposed printed pages is the product strength to be achieved and / or the efficiency with a decision criterion. For example, in the mixed product only a few special situations and in individual production of this z. B. second printing machine 03 only requires small scale products, so z. B. only a simple width execution will be sufficient. Thus, in the case of differently wide and / or differing embodiments of the two types of pressure units 02; 03 to adapt specifically to the requirements of a specific product range.

For a triple-width (6/1 or 6/2) version one of the pressure units 02; 03 or printing machines 01; 31 can on the six pages wide transfer cylinder 06; 16 each one over its length continuous, two three-page wide or three two-page width (not shown) blankets - especially metal blankets with a dimensionally stable support plate, z. As metal plate, and an elastic and / or compressible coating - be arranged. Advantageous in the context of increased variability (pop-up production, variable web width) is the execution with in Longitudinal side by side two three-page wide blankets. The blankets can each be fully circumferentially and - in the case of longitudinally several - circumferentially offset from one another.

The two types of printing units 02; 03 or printing machines 01; 31 may differ in addition to distinguishing in terms of their width and / or size - for example, in terms of printing methods. Thus, for example, the printing unit 02 of the one type can be used as an offset, as a direct printing, as a flexographic printing unit or as a printing unit of a non-impact method (printing method without printing form or inking without mechanical action of printing cylinders on the printing substrate, eg. Printing on photosensitive paper, inkjet printing or laser printing) may be formed and subject the printing press 01 to the corresponding method. The printing unit 03 of the other type may then be formed according to another of the said methods. For example, the one printing machine 01, in particular as a newspaper printing press 01, may be formed with offset printing units, while the other has one or more direct printing or flexographic printing units or non-impact printing units. Also, a printing press 01 may be formed as a newspaper press 01 having offset printing units, while the other printing press 31 has offset printing units of commercial printing (i.e., printing mechanisms with substantially horizontal web running for the high-quality commercial printing with a downstream dryer) or is designed as a commercial printing press.

The two types of printing units 02; 03 or printing machines 01; 31, in addition to or instead of a difference in the above printing methods, may differ in that one of the printing presses 01; 31 with drying of the freshly printed web, ie in the "heatset" method (for use of the term "heatset" see below), and the other without drying, ie operated in the "coldset process". The heatset printing press 31; 01 then has corresponding means for drying support 15, z. B. a dryer 15, and the associated Printing units 03; 02 are formed with correspondingly modified units and / or ancillary equipment (see below). Advantageously, a printing press 01, in particular as a newspaper press 01 with (offset) printing units (short coldset printing units 02) equipped purely for newspaper and / or coldset printing, can also be formed, while the other printing machine 31 is one or more for the semi-commercial and / or or "Heatsetdruck" trained offset printing unit (s) (short heatset printing unit (s) 03) and means for drying support 15 has. Under the header "heatset" not only the drying of the web using a thermal process, but in contrast to the "coldset" and the drying by other drying assistants, for. As UV or IR dryer, understood.

Several printing units 02 of the first type, z. B. "pure" coldset printing units 02 and / or at least one printing unit 02 of the first type, z. As coldset printing unit 02, and a funnel structure 07, are in the manner of a so-called. Line machine 01, ie in a common, to the axial direction of their printing cylinder 04; 06 vertical machine flight M1, arranged. In the Fig. 1 and 2 illustrated machine alignments M1 extend at the level of a printing cylinder 04; 06 in the length bisecting plane of symmetry and may also be referred to in this form as Maschinenmittelflucht M1. In the case of a plurality of printing units 02 of the first type in a line arrangement, the at least one funnel assembly 07 associated with the printing units 02 can additionally be arranged in this machine alignment M1 ("straight-ahead design"). The printing cylinder 04; 06 are formed in the case of offset printing, for example, as a forme cylinder 04 (imaging printing cylinder 04) and transfer cylinder 06. The funnel structure 07 is a folding unit 08, z. B. in the case of a trained as a newspaper printing machine 01 printing press 01 a coldset folding unit 08, downstream. The funnel structure 07 has one or more formers 09, which are preferably oriented such that on the former 9 accumulating material webs 11, z. B. paper webs 11, short webs 11 have a projected in the horizontal direction of transport T1, which along or parallel to Machine center alignment M1 of the first printing press 01 runs. Ie. the printed in the printing units 02 of the first type sheets 11 can be performed in so-called. Straight-ahead on the former 09. The entire first printing machine 01 designed as a line machine 01 or else a section having at least one printing unit 02 and an associated hopper structure 07 can also be designated as (first) machine line 30.

The first printing press 01 preferably has a plurality of groups of adjacent printing units 02, wherein one or two hopper assemblies 07 are or are arranged between the groups. In this way - optionally across groups - the mass product (eg newspaper) can be produced on the first printing machine 01, while on the other printing machine 31 either individual product sections for the mixed product, or a separate product z. B. higher quality and / or smaller scale and / or smaller edition can be produced.

In the printing press system, it may in principle be any o. G. Combination of two different pressure units 02; 03 or printing machines 01; 31 with different circumference and / or different width (or length of the printing cylinder 04, 06, 14, 19) act. However, the printing units 02 of the first printing press 01 are preferably designed as printing towers 02, which advantageously each have two stacked H printing units or two stacked satellite printing units. In principle, the printing towers 02 can also have four or more double printing units for the two-sided printing. The web 11 extends between the pressure points in the form of printing towers 02 printing units 02 of the first printing press 01 substantially vertically.

An illustrated machine flight M2 of the second printing press 31 or machine line 30 runs at the level of a printing cylinder 14; 16 of the second printing unit 03 in the length bisecting plane of symmetry and can in this Expression also be referred to as Maschinenmittelflucht M2.

In an advantageous embodiment of a printing machine 01 as a "pure" newspaper printing press 01, it has coldset printing units 02 for the newspaper printing as printing units 02 of the first type. In the case of printing units 02 designed as coldset printing units 02-in particular for newsprint printing-the printing cylinder 04 designed as a forme cylinder 04 has, for example, several printing plates 28 on its circumference in the longitudinal direction (FIG. Fig. 6 a) ), which in the axial direction either only a print image (single printing form 28, not shown) or a maximum of two (panoramic printing form) print images of a newspaper page, viewed in the circumferential direction of the forme cylinder 04 each carry only one of these print images. So bears the forme cylinder 04 as in Fig. 6 a) schematically shown, for example, in the axial direction next to each other four and in the case of double-sized forme cylinder 04 in the circumferential direction z. B. two printing plates 28, each with a pressure side. Simply large forme cylinders 04 have only such a pressure mold 28 in the circumferential direction. The individual printing forms 28 can be isolated or in total also be replaced in pairs by panorama printing plates with two printed pages in width. The forme cylinder 04 of the coldset pressure unit 02 has z. B. on its circumference one (simply large forme cylinder 04) or successively two (double-sized forme cylinder 04) in the longitudinal direction over the entire usable for printing length channels for receiving the printing plates 28 on. Next, the forme cylinder 04 of the coldset printing unit 02 z. B. devices (eg., Passer or axially effective stops) for the lateral alignment of four printing plates 28 side by side. The formation of the forme cylinder 04 with four printing pages or printing forms 28 side by side and four stops, which is mentioned for four printed pages, is to be applied to a forme cylinder 04 with six printed pages next to one another correspondingly with six printing plates 28 and six stops.

A printing unit 02 designed as a coldset printing unit 02 has a non-figurative illustrated inking unit for coloring the printing plate (s) 28, which is filled or operated with coldset colors. The coldset ink is characterized by special adjuvants (such as wetting agents, wax gelling agents, mineral fillers) which allow drying of the printed web 11 by repelling the ink into the paper. This is done in particular by the special combination of coldset ink and the paper used.

The guided through the coldset printing unit 02 web 11 is preferably uncoated or slightly coated paper with a maximum weight of 20 g / m ² , in particular at most 10 g / m ² , is.

In the execution of the first printing machine 01 as a coldset printing press for the newspaper printing that is the first printing press 01 with the arranged in the machine alignment M1 hopper structure 07 in straight line associated folding unit 08 z. B. formed as a newspaper folder. Trained as Zeitungsfalzwerk folding unit 08 has one or two folders, z. B. designed as a single or double folder on. The folding unit 08 may also have a plurality of individual folding apparatuses. The folder of designed as a newspaper folder folding machine 08 has z. As a cutting cylinder, a transport cylinder, a jaw cylinder and possibly a paddle wheel. Optionally, but in particular for the formation of the folder for semicommercial products, it may additionally comprise means for forming a second transverse fold. The folder of the folding unit 08 is advantageously rotationally driven by at least one drive motor mechanically independent of the printing units 02.

As a forme cylinder 14 formed printing cylinder 14 a heatset printing unit 03 for the (semi) commercial printing can be considered in one embodiment, for example, on its circumference in the longitudinal direction advantageously only one, but at most two printing plates 29, which viewed in the axial direction z. B. at least three (in two printing plates in the longitudinal direction) or z. B. six (with only one Printing form 29 in the longitudinal direction) printed images of a tabloid page (eg magazine or telephone book page), viewed in the circumferential direction of the forme cylinder 14 in each case several, z. B. at least four, wear this printed images. Thus, the forme cylinder 14 carries as in Fig. 2 b) schematically shown on the unrolled circumference, for example, both in the axial and in the circumferential direction considered only a printing plate 29, which z. B. side by side the print images of six and in the circumferential direction of four printed pages in tabloid format (eg., In magazine or phone book format) wears. In the case of two full-scale printing plates 29 on the forme cylinder 14 next to one another, the printing plates 29 have, for example, three printed pages in tabloid format next to each other. The form cylinder 14 of the heatset printing unit 03 has z. B. on its circumference extending in the longitudinal direction over the entire usable for printing length channel for receiving the printing form (s) 29. Next, the forme cylinder 14 of the heatset printing unit 03 z. B. a device (eg., One or more register or axially effective stops) for the lateral alignment of one or two printing plates 29 side by side.

In another embodiment, operated in the heatset printing unit 03 with respect to their forme cylinder 14 may be formed according to a forme cylinder 04 a coldset printing unit 03, and on its circumference in the axial direction of the number of printed pages corresponding number of printing plates, z. B. wear individual printing plates. In the case of a double-width printing unit 03 z. B. in the axial direction next to each other four, and in the case of a triple-width printing unit 03 z. B. six printing forms with printed pages z. B. a newspaper format.

The forme cylinder 14 of the heatset printing unit 03 may, for. B. an effective, ie for printing a web 21, z. B paper web 21, short web 21 have usable bale width, which corresponds to at least the corresponding number of newspaper pages of the newspaper printing machine 01 format to be printed.

The heatset printing unit 03 has an inking unit (not illustrated in the figures) for coloring the printing form (s) 29, which can be filled or operated with heatset in at least one mode of operation (heatset operation). However, if the second printing unit 03 is operated with colors for the waterless offset printing, a color of the same type or the same color can be used in the second printing unit 03 operated in heatset mode and in the first printing unit 02 operated in the coldset 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 21 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.

The web 21, which is guided through the heatset printing unit 03 in heatset mode, preferably produces satin-finished and / or more-coated paper having a coating weight of more than 10 g / m ² , eg. At least 15 g / m ^2. The paper may be of medium or higher quality in a grammage range greater than 40 g / m ² , e.g. B. in a grammage range of 55 - 90 g / m ² , in particular greater than 50 g / m ² lying, be formed. In contrast, the paper fed in coldset operation can advantageously be located in a grammage range of less than 50 g / m ² , in particular less than 40 g / m ² .

However, the heatset printing unit 03 is preferably operable either in heatset mode or else in coldset mode, wherein it is operated, for example, in the former mode of operation with heatset ink and / or with more coated paper, and in the second-mentioned mode of operation with coldset ink and / or with uncoated or slightly coated paper is. In the coldset mode, the dryer 15 can pass through in the deactivated state or it can be bypassed in a modified path become.

The printing unit 03 of the machine line 25, in particular of the heatset machine line 25 and / or the second printing machine 31 designed as a heatset and / or semi-commercial printing press, is e.g. B. designed as a printing tower 03, which preferably four stacked double printing units for the two-sided printing, z. B. so-called. Bridge or n-printing units. In principle, however, the printing tower 03 can also have or consist of two stacked H printing units or two stacked satellite printing units.

If the second printing machine 31 is designed as a commercial printing press, the printing unit 03 has an offset double printing unit with four printing couple cylinders 14 arranged vertically one above the other; 16 as well as more elaborate inking units, for example two-drum roller inking units with at least three friction cylinders located in the compactor. The form cylinder 14 are z. B. similar to the heatset printing unit mentioned with continuous mounting channel and the possibility of receiving a reaching across the entire width of the printing plate 29 is formed. Also in this case, the commercial printing units are operated with heatset ink and the printing machine has a dryer 15.

One or more of these printing units 03 of the second type, for. B. heatset printing units 03 and a heatset machine line 25, a downstream folding unit 18, z. B. Heatset folder 18 assigned. A heatset folder 18 (for semi-commercial products) advantageously has additional units in addition to the cutting cylinder, transport cylinder and jaw cylinder, for. B. means for a second longitudinal fold and / or a second transverse fold and / or a stapler and / or a Pflugfalz on.

In an axial direction of the printing cylinder 14; 16 of the printing unit (s) 03 of the second type perpendicular machine flight M2 can either only one Printing unit 03, but it can also be several printing units 03 of the second type (in the manner of a line machine) or at least one printing unit 03 and a dryer 15 and / or other units such as cooling rollers and / or coating unit can be arranged. Such an arrangement of one or more second printing units 03, z. B. together with an additional dryer 15, etc. in a machine flight M2 is referred to below as the machine line 25, in the special case as a heatset machine line 25. The machine flight M2 and / or the direction of passage of a possibly existing dryer 15 is z. B. substantially parallel to the machine flight M1.

It can be associated with the first printing machine 01 advantageously also a turning device in the superstructure 05 to the running in the first printing machine 01 webs 11 and part webs 11.1; 11.2; 11.3 to be able to turn variably into different alignments parallel to the machine center M1. Likewise, the second printing machine 31 may have in its superstructure 39 via a non-illustrated own turning device, which allows the running in the second printing press 31 webs 21 and partial webs 21.1; 21.2 to turn variably into different alignments parallel to the machine center M2 (see above).

In the FIGS. 1 to 5 , especially Fig. 1 and 2 , Embodiments for the combination of two printing machines 01; 31 or machine lines 30; 25, wherein a plurality of printing units 02; 03 of the same type may be arranged in a machine line, but the printing units 02; 03 of the same type need not be immediately adjacent to each other, but can be placed in the printing press system as required.

The two printing machines 01; 31 is as in Fig. 1 shown, in addition to the hopper structure 07 another hopper assembly 17 assigned in such a way that in one mode of operation of the printing press system a separate production with the one printing press 01 on the funnel structure 07 and with the other printing press 31 - in the example of Fig. 1 via at least one turning device 10 - on the other funnel structure 17 can be realized. As described below, it is possible in other operation of the printing press system, webs 11; 21 or partial webs 11.1; 11.2; 11.3; 21.1; 21.2 from the two printing machines 01; 31 together on a funnel assembly 07; 17 to lead.

The two funnel structures 07; 17 can - depending on machine width (ie the maximum web width to be printed and / or the number of pages (eg newspaper pages) in the axial direction of the printing cylinder 04; 06; 14; 16) of the two printing machines 01; 31 or their printing units 02, 03 - a same or a different number of horizontal as a funnel group juxtaposed former 09; 19, and / or - depending on on the two printing machines in separate production primarily to be produced products - former 09; 19 have a same or a different effective width (funnel format). So how can in Fig. 1 a funnel structure 07; 17 a group of two (or three) formers 09; 19 of a first effective width (first funnel format) and the other funnel assembly 17; 07 a group of one (or two) formers 19; 09 each one of the same or another, z. B. larger effective width (second funnel format) have. The hopper assemblies 07; 17 can thus, depending on the requirement in number and / or effective width of the former 09; 19 different. Under effective width or funnel format of the folding jig 09; 19 here is the width in the casserole area of the former 09; 19 transversely to the incoming (sub) path 11; 21 to understand. This corresponds z. B. the maximum width of a folding hopper 09; 19 to be folded Telbahn, which in turn with the respective to be folded printed page format - usually part track two pages of the corresponding format wide - corresponds. It can, for example, the one funnel structure 17; 07 a group of two formers 19; 09 next to each other and the other funnel assembly 07; 17 a group of three formers 09; 19 each have the same (same funnel format) or different effective width (not shown).

They can also differ in the applied printing process (see above) and / or in the use of a dryer 15 (see above). In the example shown, one of the printing presses 01, 31, here the second printing press 31, has a dryer 15.

FIGS. 7 and 8 show embodiments of multi-wide funnel structures 07; 17 as in the preceding embodiments for multiple width, z. B. respect. A specific format double or triple wide printing press 01; 31 can be used.

In Fig. 7 various alternatives for the execution of a - at least in a certain printed page format - triple-width funnel structure 07 are shown. The design according to funnel structure 07a has only in one plane a funnel group of three transverse to the direction of emergence of a web 11 juxtaposed folding hoppers 09 on. The effective width of these three formers 09 corresponds z. B. maximum of the effective bale length of a forme cylinder 04 of the upstream of the funnel structure 07 upstream pressure unit 02. The funnel group is the folding unit 08 downstream. In the execution of the funnel structure 07d, this has on the pathway before or after the formers 09 additionally not shown longitudinal cutting means for the central longitudinal cutting of the partial webs 11.1; 11.2; 11.3 in the region of the fold back of the longitudinally folded strand. These sub-strands of the same former 09, which are cut open on top of each other and can be placed on top of each other, can now be divided and, as required, combined with one strand or sub-strand of an adjacent former 09 via guide rollers and / or draw rollers 37. This is particularly advantageous if on one or more of the possible strand guides between the formers 09 and the folding unit 08, a further processing stage such. B. a glue device or a stapler is / are arranged. In this way, depending on the distribution of the strands, a variable assignment of the partial strands to stapled / untied or glued / unsized strands takes place.

In the embodiment of the funnel structure 07b, this has in two mutually vertically offset planes two funnel groups of three formers 09; 09 'next to each other.

In the embodiment of the funnel structure 07c, this has two superimposed groups with a different number of horizontally as a funnel group juxtaposed former 09; 09 "and / or two groups of formers 09, 19 of a different effective width (hopper format) .For example, a first of the groups is formed three times wide with respect to a first print page format and has three in view of this print page format single width former 09, while the second group with respect to a second, z. For example, the group with the larger number of formers 09 has an effective width, which, for example, corresponds to the maximum effective bale length of a forme cylinder 04 By contrast, the wider formers 09 "have a significantly larger effective width, ie, for example, by a factor of 1.1, in particular a factor of 1.2, than that of the formers 09 of the first group , This funnel arrangement of the funnel structure 07c is particularly advantageous in relation to printing presses 01 which are set up for printing on variable web widths and / or for producing products of different printed page formats. Also advantageous is this arrangement for the production of such. "Pop-up" products through the two combined printing presses. A pop-up product is characterized in that in the folded or combined product, one part has a greater width and / or length than another part, so that a supernatant of a partial product over another partial product is formed. This supernatant in the finished product is advantageously at least 10 mm, in particular at least 20 mm wide and preferably has a part of a printed image, for. For example, text.

In Fig. 8 are different alternatives for the execution of a - at least in a certain printed page format - double-width hopper assembly 17. The execution according to hopper assembly 17a has only in one plane a funnel group of two transverse to the direction of feed of a web 21 juxtaposed former 19. The effective width of these two formers 19 corresponds z. In the execution of the hopper assembly 17c, this has on the path before or after the formers 19 additionally not shown longitudinal cutting devices for the central longitudinal cutting of the partial webs 21.1; 21.2 in the region of the fold back of the longitudinally folded strand. These sub-strands of the same former 19, which are cut open on top of each other and can be placed on top of each other, can now be divided and, as required, combined with a strand or sub-strand of an adjacent former 19 via guide and / or draw rollers 38. This is particularly advantageous if on one or more of the possible strand guides between the formers 19 and the folding unit 18, a further processing stage such. B. a glue device or a stapler is / are arranged. In this way, depending on the distribution of the strands, a variable assignment of the partial strands to stapled / untied or glued / unsized strands takes place.

In the embodiment of the funnel structure 17b, the latter has, in vertically offset planes, two funnel groups each of two formers 19; 19 'next to each other.

In an embodiment of the funnel structure 17, not shown, this can be made according to the principle Fig. 7 (There funnel structure 07c) also have two superimposed groups with a different number of horizontally as a funnel group juxtaposed formers and / or two groups of formers of a different effective width (funnel format). For example, a first of the groups is double-width-wise with respect to a first page size and has two single width formers 19 with respect to this page size, while above or below a single, significantly wider former, or a group of two wider folders 19; 19 'is arranged. In this case, the effective width is referred to as the funnel structure 07c in a figurative sense. With such a design of the funnel structure 07 can also iVm the two printing machines 01; 31 a pop-up product will be generated.

For all preceding examples of the printing press system, it is provided in a development, at least one of the printing units 02; 03 and / or the or a funnel structure 07; 17 of the first or second printing machine 01; 31 to form so-called "pop-up" products (see Fig. 7, 8 . 9 and 10 ).

For this purpose, in a first embodiment, a hopper assembly 07 of the first printing press 01 with two groups of formers 09; Be formed 09 ', the effective widths differ and therefore the folding of partial webs 11.1; 11.2; 11.3 different widths are formed. In a further development, formers 09; 09 'at least one of the two funnel groups in a direction transverse to the web direction of travel (eg., Transverse direction T1) formed movable and possibly be changed by removable or fold-away inserts in their effective width. Depending on the partial web width then the two adjacent formers 09; 09 'in a relative position to each other spent such that a distance a09; a09 'the funnel tips differently adapted to the partial web width may be different ( Fig. 9 a) to c)). Fig. 9 shows the relationships schematically at two pressure units 02; 03, which of tracks 11; 21 different web width b1; be passed through b2. The partial webs 11.1; 11.2; 21.1; 21.2 of the narrower lane 11; 21 are on the funnel group with the smaller distance a09 between the Trichtemasen the Former 09; 09 'out while the partial webs 21.1; 21.2; 11.1; 11.2 of the wider track 21, 11 onto the funnel group with the greater distance a09 'between the funnel nose of the former 09'; 09 are guided. In Fig. 9 this principle was based on printed in tabloid printing webs 11; 21 explained with lying tabloid printed pages. Here are between each printing unit 02; 03 and funnel structure 07; 17 or former 09; 09 'next to the longitudinal cutting device 34; 36 for the chief cutting lines additional longitudinal cutting devices 44; 46 (secondary cutting lines) provided, which the partial webs 11.1; 11.2; 21.1; 21.2 longitudinally cut in the area of the folded spine to be created or already produced. However, the embodiment shown for tabloid formats is to be transferred in the same way to broadsheet production, in which case, however, usually no cut is made in the auxiliary cutting lines and the printed pages are formed as standing printed pages, which in the presentation of the Fig. 9 a) "bold" for a printed page indicated to correspond to about two tabloid pages.

In another variant, the former 09; 09 'with the larger, maximum required effective width - for example, as shown Fig. 10 be firmly installed, but with the object in the above embodiments, orbit 21, or partial webs 21.1; 21.2 in the mixed mode with the formation of pop-ups the wider sub-paths 21.1; 21.2 and respond accordingly. The printing units 03 are then formed with a width which is correspondingly greater than the multiple of the printed page format of the first printing press 01, so that a projection can remain per printing page width. Depending on the partial web width, the web 21 or partial webs 21.1 coming from the side and to be introduced into the stream of the first printing machine 01; 21.2, the positioning of the - advantageously transversely to the machine alignment M1 of the first printing press M1 - movable turning bars 32, the respective partial web 21.1; 21.2 aligned with the respective funnel tip. For a "normal" mixed production, the adjacent partial webs 21.1; 21.2 due to the increased effective funnel width spaced from each other ( Fig. 10 a) ). In pop-up production maximum supernatant, ie maximum width, can, depending on zugespegendem former 09; 09 ', the cut and subdued partial webs 21.1; 21.2 directly next to each other on the adjacent formers 09 'run ( Fig. 10b) ). Depending on the positioning of the turning bars 32, the two partial webs 21.1; 21.2 are also one above the other on a same former 09 'out.
