Method and device for producing a product section in a web-processing machine and product sections

The invention relates to a method and a device for producing a product section in a web-processing machine as well as product sections according to the preamble of claim 1 or 2 or 13 or 24 or 27.

US Pat. No. 4,671,501 A discloses a device for producing a folded product with two folding hoppers arranged one after the other, the transport directions of which project in the horizontal direction are substantially orthogonal to one another. A four-side-wide web is first cut into two two-sided partial webs, each two newspaper pages wide sub-webs then led side by side over the two flanks of the first of the two former and thereby stacked and then led the resulting two-sided strands for Längsfalzung centered on the downstream former.

DE 10 2005 036 451 A1 discloses a device for producing a product section in a web-processing machine with a first and a second folding hopper arranged downstream of one another on the web path, whose transport directions projected in the horizontal direction are substantially orthogonal to one another.

In one embodiment, WO 2005/105447 A1 discloses a superstructure of a web-fed printing machine, wherein a printed web strand is wrapped on one or both sides by a plow folding device, and the strand so folded is guided onto a former for longitudinal folding. In EP 1 595 837 A1, in one mode of operation, a web is guided onto a former corresponding to the web width. In another mode, a sub-strand of the web is guided on the laterally moving hopper, and another sub-strand on a corresponding to a funnel edge oriented turning bar.

The invention has for its object to provide a method and an apparatus for producing a product section in a web-processing machine and product sections.

The object is achieved by the features of claim 1 or 2 or 13 or 24 or 27.

The hopper assembly 07 has at least one former 1 1 .1; preferably next to each other several, z. B. (exemplary in the first embodiment) two or (exemplary in the second embodiment) three, former 1 1.1; 1 1.2 (1 1.3) on which the tracks 03.1; 03.2 or their partial webs 03.1 a; 03.1b (03.1c) 03.2a; 03.2b; (03.2c) z. B. respect. A transport direction T of the printing machine 01 considered can accrue in straight-ahead. The transport direction T is z. B. in or parallel to a plane E (see FIG. 2), which is substantially perpendicular to rotation axes of printing cylinders 12; 13 of the printing unit 04 is. In this case, that plane E, which, for example, by the central section of the printing cylinder 12; 13 runs, z. B. be referred to as the machine center plane M. The transport direction T1 on the former 1 1.1; 1 1 .2 (1 1 .3) also lies in this plane E or parallel to it. A the former 1 1.1; 1 1.2 (1 1.3) associated, designed as funnel inlet roller 10 roller 10, z. B. tension roller 10, extends with its axis of rotation substantially parallel to the axis of rotation of the same web 03 associated printing cylinders 12; 13. The funnel structure 07 in the example according to FIG. 1 to FIG. 3 shows by way of example a group of two folding funnels 1 1 .1 arranged side by side at the same machine height. 1 1 .3 on. However, depending on the machine width and type, only a single former, a single group of three (second example according to FIG. 5 to FIG. 8 or FIG. 10) or more former, or two or even three groups one above the other, each with one , two, three or even more formers 1 1 .i be provided.

In the embodiment of Figures 1 to 3 representation is an example of a printing press with double-width printing unit cylinders 12; 13 formers 1 1.1; 1 1 .2, and in FIGS. 4 to 8 or 10 and 1 1 by way of example a printing machine with triple-width printing unit cylinders 12; 13, z. B. transfer cylinder 12 and forme cylinder 13, shown. "Double-width" means that the printing unit cylinders 12, 13 have a maximum effective width for the printing, which is the width of four printed pages, one of the widest machine-standard formats, such as here, viewed transversely to the web 03.1; lying side of a tabloid format in tabloid arrangement, corresponds to the same is single-width and triple-width with to apply two or six sides which can be arranged side by side.

FIGS. 2 and 5 each show a schematic plan view of a printing press according to FIG. 1 or FIG. 4, wherein one of the printing units 04.1; 04.2, 04.3 in particular at least the next to the funnel structure printing unit 04.2 or 04.3, in the manner of a standard production on its cylinders 13 one of the nominal diameter corresponding number of printed pages of the standard size F, in Fig. 2 four printed pages and in Fig. 5 six printed pages, side by side wearing. In the schematic illustrations of the printing units are on both sides of the respective web 03.1; 03.2 only the occupied with printed images form cylinder 13 is shown. The between form cylinders 13 and web 03.1; 03.2 to be arranged for the offset printing transfer cylinder 12 are not shown here. If all the printing units 04.i producing the same folding apparatus 08 at the same time or their forme cylinder 13 are occupied by merely printed pages of the standard format F, customary tabloid products can be produced in a standard production:

With the arrangement of the funnel structure 07 shown in Fig. 2 and Fig. 3 with two formers 1 1 .1; 1 1.2 are in a first mode of operation (i.e., production of standard products without folding legs, see above) via the two former 1 1.1; 1 1 .2 in tabloid production from one or more four-side webs 03.1; 03.2 after the longitudinal section in the alignment between the formers 1 1 .1; 1 1.2 by a longitudinal cutting device 29 in partial webs and a longitudinal section in the alignment of the middle of the funnel by the longitudinal cutting means 25 (one hidden in Fig. 2) two strands with cut at the Falzrücken layers produced and further processed in the folding apparatus 08.

With the arrangement of the funnel structure 07 shown in FIG. 5 to FIG. 8 or FIG. 10 with three formers 1 1.1; 1 1 .2 side by side are in a first mode of operation (ie production of standard products without folding leg or without supernatant; the three formers 1 1.1; 1 1 .2 in tabloid production from one or more six-side webs 03.1; 03.2; 03.3 after the longitudinal section in the alignment between the formers 1 1 .1; 1 1.2 by a longitudinal cutting device 26 and a longitudinal section in the alignment of the middle of the hopper by the longitudinal cutting means 25 three strands produced at the Falzrücken cut layers produced and further processed in the folding apparatus 08.

In this first mode of operation, the standard production, the forme cylinder 13 of all on the same folder 08 producing printing units 04 are only printed with printed images of printed pages of the standard size F or all on the same folder 08 running tracks 03 printed only with printed images of printed pages of the standard format F. , In this case, the number of printed pages corresponding to the nominal width can be provided side by side or, in the case of partially wide webs, fewer such printed pages can be provided side by side. The thus printed webs 01 are then all in one- or two-sided part webs 03.1 b; 03.2b cut and ultimately on the former 1 1 .1; 1 1.2; 1 1 .3 out. In the case of tabloid production described here, two-sided partial webs 03.1 b; 03.2b in front of the former 1 1 .1; 1 1.2; 1 1 .3 each cut into single-sided web strands.

Notwithstanding this first mode of operation (standard production), in a second mode of operation (special production) at least one partial web 03.1b; printed in particular in comparison with a printed page of the standard format F; 03.2b with wider printed pages of a special format S; S 'printed - web 03.1 or partial web 03.1 a guided over a trained as Pflugfalzeinrichtung 18 Längsfalzvorrichtung 18, and then as a sub-strand 23, which has at least one embarked by the Pflugfalzeinrichtung 18 page, with at least one via a former 1 1.1; 1 1 .2; 1 1 .3 led sub-strand 24 is brought together as a strand bundle before this is cut transversely in a cross-cutting device 17 in product sections 16. In addition to the significant difference in functionality and the achievable product, there is a significant difference in the Pflugfalzvorrichtung 18 compared to the "normal" former, that when passing through the Pflugfalzvorrichtung 18, the plane of the strand (partial web 03.1 a and emerging sub-strand 23) in an im The axes of rotation of two downstream, in Fig. 12 schematically indicated folding rollers 28 extend in a same direction as the axis of rotation of a last, the plow folding device upstream roller 20th When passing through a former, however, the planes of the incoming and outgoing strand and also the axes of rotation of the last upstream and first subordinate rollers 20, 28 are rotated relative to each other The plow folding device 18 is preferably excluded ebildet, both sides or only one side to hit an edge of the web 03 or part of web 03a. It can be designed to selectively strike one or two edges and / or with respect to the wrapping width adjustable. In principle, however, the plow folding device 18 can also be designed in a modification to produce a so-called "Altarfalzes", a "Deltafalzes" or a "Wickellfalzes".

The partial path 03.1 a guided via the plow folding device 18 does not pass through the former 1 1 .1 in the illustrated embodiments; 1 1 .2; 1 1.3 or learns at least by none of the former 1 1 .1; 1 1 .2; 1 1.3 a longitudinal fold. Preferably, the partial web 03.1 a guided via the plow folding device 18 experiences on its path before or after the plow folding device 18 in its transport direction T projected in the horizontal direction; T2 a change of direction by 90 °. This is done via an odd number, in particular one, of turning bars 19 and then at least one guide roller 27th

In a variant in which the partial strand 23 hammered in by the plow folding device 18 has a width which corresponds to the width of a pressure side of the Standard format corresponds to F or less, the embossed sub-strand 23 can also - without forming a longitudinal fold - together with a longitudinally cut strip of a standard format F printed and not embossed part web without turning to one of two hopper edges of a former 1 1.1; 1 1.2; 1 1 .3 be led.

The arrangement of the plow folding device 18 from the example of FIGS. 1 to 3 of the double-width machine is to be applied to the arrangement in a triple-width machine according to FIGS. 4 to 8 and vice versa.

In this second mode of operation, the special production, the forme cylinder 13 of at least one on the folding unit 08 producing printing unit 04.1 side by side with print images of printed pages of the standard size F and with printing of printed pages of a special format S; S 'occupied or the such a printing unit 04.1 continuous web 03.1 side by side with print images of printed pages of the standard size F and print images of printed pages of the special size S; S 'printed. The print image of the print page of the special format S; S 'can be represented by dashed lines as S as an example, compared to the standard format F larger continuous print on a wider than a standard format F wider printing form, eg panoramic printing form, or it can be as solid and S' from a printed page corresponding to the standard format F (for example, on a first printing form) and a subsequent, only compared to the standard format narrow part-width printed image (eg, on a second printing form) put together. In the former case, the partial web 03.1a corresponding to part of the web 03.1 downstream of the plow folding device 18 is or is printed with a continuous printed image of the printed page of the special format S, and in the second-mentioned case side-by-side with a standard size F and a part-width printed page. If the partial web 03.1 a to be driven in should be turned on both sides (folding edge 26 above and below), the former variant is to be preferred. The width of two folding frames 26 (see below) to be produced in this case in the product to be produced are then to be taken into account on both sides of a printing page corresponding to the standard format F for the printing width of the special format S. The partial path 03.1 a to be driven in on both sides then has the corresponding width. A part of the web 03.1 which is downstream of a sub-web 03.1b which is not to be driven in is printed only with printed images of printed pages of the standard format F and, if appropriate, after slitting on one of the former 1 1.1; 1 1.2; 1 1 .3 out.

In this second mode z. B. the forme cylinder 13 at least one other on the same folding unit 08 producing printing unit 04.2 occupied only with printed images of printed pages of the standard size F or printed by this printing unit 04.2 printed webs 03.2 only with printed pages of the standard format F. In this case, the number of printed pages (four or six) corresponding to the nominal width can again be provided side by side or, in the case of partially wide webs, fewer such printed pages next to one another. The thus printed webs 01 are then all in one- or two-sided part webs 03.1 b; 03.2b cut, about the former 1 1.1; 1 1 .2; 1 1.3 out and brought together with the at least one embossed web strand 23 before the folder 08.

In the two exemplary embodiments presented, the sub-path to be driven 03.1 a undergoes both a change of direction (in a direction transverse to the machine center plane M) and an edge-side impact (one- or two-sided), and is then subsection 23 without a former 1 1 .1 ; 1 1.2; 1 1.3 to be performed at the latest with entry into the folder 08 a strand 15 of at least one via a former 1 1.1; 1 1.2; 1 1 .3 guided partial path 03.1 b; 03.2b added. The direction change takes place in the first embodiment, and in the second embodiment after passing through the Pflugfalzeinrichtung. In the embodiment set out in FIGS. 1 to 3, the above-described change in direction is effected by 90 ° for the sub-path 03.1a to be driven, and -z. B. on an outside of the printing press at substantially vertical web running direction - the turning over the Pflugfalzeinrichtung 18th

In the first embodiment according to FIGS. 1 to 3, the roller 20 upstream of the plow folding device 18, advantageously forcibly driven tension roller 20, runs with its axis of rotation substantially perpendicular to the axis of rotation of the same web 03.1 associated printing cylinder 12; 13 and / or perpendicular to the axis of rotation of the former 1 1 .1; 1 1.2 directly upstream hopper inlet roller 10. The tension roller 20 is preferably arranged in the web path between a turning bar 19 and the plow folding device 18. Preferably, in the web path behind the Pflugfalzeinrichtung 18, in particular at the output of the Pflugfalzeinrichtung 18, the further, shown in FIG. 12, roller 28, z. B. draw roller 28, in particular a the fold of the impact pressing pair of rollers 28, provided, the axis of rotation (s) runs substantially parallel to the upstream draw roller 20 and / or substantially parallel to the transverse extent of the entering into the Pflugfalzeinrichtung 18 web or run.

As can be seen in the synopsis of FIGS. 1 and 3, a web 03 or part web 03a initially running in the transport direction T (symbolized by Θ in FIG. 3) is projected over at least one by 45 ° or -45 ° to the horizontal Transport direction T of an incoming web 03 inclined turning bar 19 deflected by 90 ° in a new transport direction T2, in which case the projected into the horizontal transport directions T and T2 are orthogonal to each other. On the railway path downstream of the turning bar 19, the deflected path 03.1 or partial path 03.1a passes through the draw roller 20 and is guided over the plow folding device 18. When passing through the Pflugfalzeinrichtung 18 is unilaterally or on both sides by specially shaped elements at least one side of the web 03.1 or partial web 03.1 a taken while at least a central part of this strand continues in the transport direction T2 (schematically in Fig. 12).

This strand 23 having the at least one embossed edge can now be laid, as shown in FIG. 3, via one or more guide rollers 27 either on the machine side having the plow folding device 18 or on the opposite machine side with one or more of the one by the former 1 .1 ; 1 1.2 from partial webs 03.1 b; 03.2a; 03.2b formed strand 24 or strands 24 are merged (Fig 3a, Fig. 3c). However, in the case of several funnels, it can also be between the formers 1 1.1; 1 1 .2 are passed (Fig. 3b) or on the opposite side of the plow folding 18 having machine side with one or more strands 24 (Fig. 3c) are merged. Depending on the orientation of the downstream folding apparatus 08 (here to the left) and the choice of genanst strand guide is taken strand 23 or from this resulting by transverse cutting, the at least one folding edge 26 having position in the final transverse folded product as the innermost layer, as a position between Normal layers, or as outermost layer (see Fig. 9). The guide rollers 27 serve to guide the sub-strand 23 and are oriented with its axis of rotation parallel to a transport cylinder and / or cutting cylinder of the downstream folding apparatus 08.

In the embodiment set forth in FIGS. 4 to 8, for the partial web 03.1 a to be driven in, first of all, the turning over the plow folding device 18 takes place - eg. B. in the superstructure along a plane parallel to the machine center plane M transport direction T, then the above direction change by 90 ° and subsequently guiding via appropriate guide rollers 27 to the desired position in the subsequent weiterzuverarbeitenden strand 15 in the folder 08. Depending on the leadership on guide rollers 27 may be taken Substrand 23 without passing through a former 1 1 .1; 1 1.2; 1 1.3 on one or the other side of the machine (around the former or the former 1 1.1; 1 1 .2, 1 1.3 around) or in multiple formers 1 1 .1; 1 1.2; 1 1 .3 between two adjacent ones Formers 1 1.1; 1 1.2; 1 1 .3 guided and with one or more of / by the / the former 1 1 .1; 1 1.2; 1 1.3 from partial webs 03.1 b; 03.2a; 03.2b formed strand 24 or strands 24 are merged (schematically all shown in Fig. 6).

A possibly the Pflugfalzeinrichtung 18 upstream or downstream roller 20 extends here - if provided - in this first embodiment with its axis of rotation substantially parallel to the axis of rotation of the same web 03.1 associated printing cylinders 12; 13 and / or parallel to the axis of rotation of the former 1 1.1; 1 1.2; 1 1 .3 directly upstream hopper inlet roller 10. Preferably, in the path behind the Pflugfalzeinrichtung 18, in particular at the exit of Pflugfalzeinrichtung 18, the further, shown in FIG. 12, roller 28, z. B. draw roller 28, in particular a the fold of the impact pressing roller pair 28, provided, the axis of rotation (s) runs or extend substantially parallel to the transverse extent of the entering into the Pflugfalzeinrichtung 18 web.

As can be seen in the synopsis of FIGS. 5 and 6 (in FIG. 6, however, the plow folding device 18 is covered by the turning bar 19), a web 03 or part web which initially runs in the transport direction T (symbolized by Θ in FIG 03a initially embossed on one or both sides of the edge by the Pflugfalzeinrichtung 18, subsequently at least one by 45 ° or -45 ° to the projected in the Hσizontale transport direction T an incoming web 03 inclined turning bar 19 by 90 ° in a new transport direction T2 (-. T2) deflected, in which case the projected in the horizontal transport directions T and T2 are orthogonal to each other. On the path downstream of the turning bar 19 of the embossed web strand 23 is now according to the desired position in the strand 15 to be formed via at least one guide roller 27 to the or the former 1 1.1; 1 1 .2; 1 1.3 out and with at least one by the / the former 1 1 .1; 1 1.2; 1 1.3 from partial webs 03.1 b; 03.2a; 03.2b formed strand 24 or strands 24 merged (see above to FIG. Fig. 6). Depending on the orientation of the downstream folding apparatus 08 (here display to the left) and / or the choice of said strand guide is taken strand 23 or from this resulting by transverse cutting, the at least one folding edge 26 having position in the final cross-folded product as the innermost layer, as a position between normal layers, or as outermost layer (see Fig. 9). By choosing the orientation of the turning bar 19 and / or by the direction of the wrap (from bottom to top or vice versa), the position of the tab 26 on the tab 26 having arc selectable. This can be arranged folded on the side head or side leg to the front or to the rear. In the present example of Fig. 5, for example, viewed in plan view in the direction of transport T left side of the strand 03.1 a is beaten towards the web bottom, from below around the (by 45 ° counterclockwise relative to the transport direction T inclined) turning bar by the Pflugfalzeinrichtung 19 led and the sub-strand 23 then initially deflected to the left side of the machine, where it is guided over a guide roller 27 down. The product layer having the tab 26 then has the pool eg on the side head on the back (FIG. 6 a). This position is, depending on the positioning of the sub-strand 23 when summarizing before, between or behind the other strands 24 then arranged in Quergefalzten product as the innermost, intermediate or outermost layer.

Would, as indicated by the dashed line 23 shown in Fig. 5, the turning bar rotated by 90 ° (ie, clocked at 45 ° clockwise to T) and divert the sub-strand 23 to the other side of the machine, the turner bar in reverse Way around (from top to bottom) or the web 03.1 a is taken by the Pflugfalzeinrichtung 18 upwards, so the tab 26 would be in the later product z. B. on the page header on the front of the relevant sheet arranged (Fig. 6b). For relative position to other bows see above.

In Fig. 7, the two other possibilities of a tab 26 are shown on a sheet. In addition, this is exemplified by an embodiment, with the the mixed formats F; S printing unit 04.1 only a few pages are printed side by side. However, this is independently applicable to the embodiments of FIGS. 5 and 6 and vice versa. In the present example of FIG. 7, the plow folding device 18, for example, again takes the left side of the strand 03.1 a, as seen in plan view in the direction of transport T, towards the underside of the web, guided around the turning bar 19 from below, and then the sub strand 23 around the correspondingly oriented turning bar 19 (inclined at 45 ° counterclockwise to T) to the right side of the machine., Where it is guided over a guide roller 27 down. The product layer having the tab 26 then has the tab 26 then, for example, on the side foot on the front side (FIG. 8a). This position is again, depending on the positioning of the sub-strand 23 when summarizing before, between or behind the other strands 24 then arranged in the transverse folded product as the innermost, intermediate layer or outermost layer.

Would, as indicated by the dashed line 23 indicated in Fig. 7, the turning bar to be rotated by 90 ° and the sub-strand 23 deflect to the other side of the machine, with the turner bar in the reverse manner (from top to bottom) drive around or the web 03.1 a is hit by the Pflugfalzeinrichtung 18 upwards, so the tab 26 would be in the later product z. B. on the page head on the back of the relevant sheet arranged (Fig. 8b). For relative position to other sheets see above.

In one of the printing units 04.1, the web 03.1 is thus printed with a printed image which, in addition to the standard printing side, has a projection 32 on the tabloid foot or head. This in the width of a standard page and the supernatant 32 corresponding web strand is separated as a sub-web 03.1 a after the printing unit 03.1 and the supernatant 32 taken by means of Pflugfalzvorrichtung 18. The strand 23 with the impact is in the first embodiment before and in the second embodiment thereafter via the turning bar 19 - z. B. large diameter and / or enlarged Length (see below) - deflected by 90 ° and optionally on one of the two machine sides or between formers 1 1 .1; 1 1 .2; 1 1.3 together with at least one of a former 1 1 .1; 1 1.2; 1 1.3 guided strand 24 fed to the folding apparatus 08. This results in the illustrated tabloid product in which a single paper layer has a tab 26 on the foot and / or head of the tabloid sides. The tab 26 may be directed in the tabloid book inward or outward and be mounted either in the outer or the inner layer or at certain locations within the tabloid book.

For all versions it is - as far as possible and useful for the product in question - advantageous if the turning bar 19 is looped by the partial web 03.1 a or the sub-strand 23 on its not the tab 26 having web page or is.

Such tabs are usually known in magazines or other tabloid products in such a way that the folded edge for the tab 26 is parallel to the spine and the format is changed by opening a tab 26 only in its width, but not in height. However, should high-level representations - e.g. Illustration of a skyscraper, etc. - be arranged in a tabloid product, it may be of particular advantage, the format for the user through the illustrated tabs 26 and folding legs 26 (at the top and / or bottom side edge) in the product height by opening this tab (n) 26 (folding leg 26) to make enlargeable. Fig. 9 shows product sections, which can be obtained by transverse cutting of the strand bundle 15 in a cross-cutting device 17 of the folding apparatus 08 and two-sided turning of the partial web 03.1 a.

In Fig. 9 are different from the tabloid strand in normal production product strands or product sections shown, the finished, ie the cut tabloid in the upper and / or lower edge hinged, in the unfolded state at least one layer (special situation) with at least one of the Product height extending tab 26 has. A folded edge 34 of the tab 26 runs as in the illustrations according to FIG. 6 and FIG. 8 perpendicular to the product back 33 (transverse fold). FIGS. 9 show the respective product section with a product gap already folded transversely after transverse cutting (and partially opened here for reasons of representation). The illustrated layers without flap 26 (normal layers) do not have to correspond to the number of actually collated normal layers but merely represent the position of the special layer relative to one or more normal layers in the product (front layer, back layer, intermediate layer). In FIGS. 9A and 9B, a normal position for one or more normal layers arranged one above the other may be shown. The examples in FIG. 9 are exemplified for the above-mentioned embodiments of the printing press according to FIGS. 1 to 4 and FIGS. 5 to 8 with partial webs 03.1 a embossed on both sides, ie with tabs arranged on the head and on the foot. However, the illustrations are also applicable to the above-mentioned embodiments with only one head or foot-side tab 26entsprechend. In the case of head and foot-side tab 26, the trajectory 03.1 a is guided by the Pflugfalzeinrichtung that takes place on both sides a beating. In the other case, as shown above

Depending on the leadership of the embossed edge having strand 23 to the or the other strand 24 or strands 24 can ultimately with the hinged tab 26 (or the folding legs 26) provided product section in the finished strand bundle 15 and finished product section as outer layer (Figure 9c, h), between "normal" tabloid layers (Figure 9a, b, d, e, f, i) or inner layer (Figure 9g), depending on whether the wrapping of the edges or the edge of the web 03 or part of the web 03a by means of Pflugfalzeinrichtung 18 down or up, or the turning around the turning bar 19 from bottom to top or from top to bottom, the orientation of the tab 26 can be provided in either side the way that the hinged side in the product is a front or back side. As indicated in FIGS. 9g, h, i by the punctured reinforcements, it may be advantageous that a perforating device 21, in particular a transverse perforating device, is provided on the path of the plow folding device 18, which preferably does not support the web 03 or part web 03a entire width, but only in sections, especially in the area of the edges to be handled, transversely perforated. Thus, the folding leg 26, z. B. in the event that the two sides of a same web section downstream generated by transverse folding is not located in the product center as a panorama page, yet laterally separate easily and thus hinged.

In a refinement shown by way of example in FIGS. 9e and 9f, provision may also be made for the layer having the folding edge or folding leg 26 to be arranged in such a way or produced with a larger dimension that it can be removed from the finished product at the upper end. or underside looks out and therefore easily recognizable or possibly removed. Such a layer is also referred to as a "pop-up." The part of this "pop-up" protruding from the dimensions of the normal layers can be printed with information, for example about the content. The production can be carried out either by, as indicated in Fig. 1 by dashed arrows, the Pflugfalzeinrichtung 18 in or against the transport direction T movable or in Fig. 5 or 7, the turning bar 19 transversely to and / or in the transport direction T is movable and Thus, the position of the strand 23 to the strand 24 or strand bundle 15 is offset. Alternatively, however, a suitably wider initial partial web 03a may be chosen for the strand 23 and / or a side impact may be made (e.g., shortening of the folding leg 26) so that the folded edge of the corresponding folding leg 26 protrudes from the product.

In an advantageous embodiment and / or operating situation to be considered in relation to the above Genantes further or possibly independently, the printing press can be used without great effort a product containing a popup layer will be created. Here, the opposite of the normal format wider print image-carrying partial web 03.1 a without passing through any existing Pflugfalzeinrichtung 18 (ie without impacting a web edge) on the turning bar 18 and the guide roller (s) 27 out and this sub-strand 23 (with a special format corresponding Width) one or more about former 1 1.1; 1 1 .2; 1 1.3 mixed strands 24 (with the narrower format F corresponding width) mixed. For the assignment of the form cylinder 13 with print images of the standard format F and with print images of the standard format F and at the same time the wider special format S; S 'is the above apply. Fig. 1 1 shows in the embodiment a) exemplarily a product with a trained as a pop-up inner layer (obtained by admixture of this sub-strand 23 to the other sub-strands 24 as the transport cylinder 31 of the folder 08 next layer of the strand 15), and in the embodiment according to b) exemplarily a product with an intermediate layer formed as a pop-up (obtained by admixing this partial strand 23 between two of the other, via the formers 1 1 .1; 1 1.2, 1 1.3 out, the standard format F having partial strands 24) , The trained as a pop-up position has next to a "normal" print page in standard format thus on the head and / or foot on a projection 32 and a non-folded tab 32.

In a printing unit 04.1 a web 03.1 is printed, the printed image z. B. on the head or foot over the standard format F extended print image (a special size S; S '), ie the supernatant 32 has. This in the width of a standard page and the supernatant 32 corresponding web strand is separated as a sub-web 03.1 a after the printing unit 03.1, on the turning bar 19 - z. B. with large diameter and / or increased length (see below) - deflected by 90 ° and either one of the two sides of the machine or between formers 1 1.1; 1 1 .2; 1 1.3 together with at least one of a former 1 1 .1; 1 1 .2; 1 1.3 guided strand 24 fed to the folding apparatus 08. As a result, tabloid products which are shown by way of example in FIG. 1 1 and in which a single paper layer z. B. at the top of the tabloid pages Supernatant 32 has. This projection 32 can be localized either in the outer or the inner layer or at certain locations within the tabloid book. The supernatant 32 is particularly evident due to its prominent position in the finished newspaper product and can be printed, for example, with a special advertisement or headline.

The turning bar 19 is preferably transverse to the transport direction T, d. H. formed transversely to the direction of the incoming web 03.1 a movable and positionable. At least it is advantageous to at least the width of a track side to be hit, d. H. to the height of the desired tab 26, z. B. at least a quarter of a print image width of the standard format movable. In an advantageous development, it is movable such that it is in the flight of all two-sideways partial webs 03.1; 03.2 is available.

In a further advantageous embodiment of the turning bar 19, this - at least in its co-operating with the divisional partial web 03.1 a longitudinal section - formed as a luftbeblasene or inflatable turning bar in the air outlet openings whose projected to the width of the incoming web and effective for the deflection length at least the 1, 25 times, preferably at least 1.5 times, a format F to be printed in the machine by default. For a double width machine, this corresponds e.g. the at least 1, 25 or 1, 5 times the fourth part of the maximum usable bale length of the forme cylinder 13, for a triple-width machine, this corresponds e.g. the at least 1, 25 or 1, 5 times the sixth part of the maximum usable bale length of the forme cylinder 13.

Since at tracks or partial webs 03.1 a with impact the risk of a reduction in quality (wrinkling) when passing over the turning bar 19, in an advantageous embodiment, a turner bar 19 with a relatively large diameter d2, z. B. d2 at leasti OO mm, in particular at least 1 10 mm, provided (Fig. 13). With the larger diameter d2> d1 results at 180 ° wrap and simple geometric consideration for the difference in length between the outer and inner layers L1; L1 (in FIG. 12) approximately the following relationship:

ΔL1 = (d1 + 6/2 ^* d) ^* π / 2 - (d1 + 2/2 ^* d) ^* π / 2 = 4/2 ^* d ^* π / 2 ΔL2 = (d2 + 6/2 ^* d) ^* π / 2 - (d2 + 2/2 ^* d) ^* π / 2 = 4/2 ^* d ^* π / 2 ΔL1 = ΔL2

The larger diameter d2 causes the theoretical length difference ΔL, which is the same for a layer thickness s and the wrap angle π / 2, which is the same for both bar diameters, to be distributed over a greater distance L. Ie. the quotient ΔL / L becomes smaller. With the larger diameter d2 of the turning bar 19 thus reduces the difference in tensile stresses of the outer to inner layer and thereby also reduces the risk of wrinkling.

For all embodiments, a stapler - in particular Querheftapparat - may be arranged in one or more strand paths of the strands 24 or in the strand path of the strand bundle 15.

The processable to the product section 16 tracks 03.1; 03.2; 03.3 can be previously printed by the printing units 04 in the coldset or Heatset method. In the latter case, for. B. the relevant, the web 03 in the heatset printing process printing unit 04 downstream of the web a not shown dryer. Depending on the design of the printing machine 01, both inner sections and the outer sheath section may be formed from sheets 03 printed in the coldset or heatset process or also mixed with sheets 03 printed in the coldset and heatset processes. The printing machine 01 then has, according to the requirement, none, one or more dryers. LIST OF REFERENCE NUMBERS
