Description

The present invention relates to a process for producing an overprinted printed product.

So-called superpanorama printed products or newspapers are known from the prior art, which - starting from a "normal" newspaper, for example in broadsheet format - with opened newspaper at their left and right outer edges each have a further outwardly hinged newspaper page, which are conventionally connected with an adhesive strip to the outer edges of the newspaper pages. In this way, representations of very wide images or even additional text can be reproduced.

From the DE 10 2009 002 091 A1 Such a conventional method is known in which a printing material web is first cut longitudinally in two web strands, wherein a web strand is turned over a turning device on the web of the other web strand, then the other web strand is also cut longitudinally in two more - narrower - web strands, then the outer edges of the two narrower web strands are glued to the outer edges of the reversed web strand via an adhesive device, and finally the thus formed total web strand is passed through a former, which folds the total web strand centered, so that a newspaper in Superpanorama format is produced with glued pages ,

A disadvantage of this conventional method is that a lateral alignment of the narrower web strands relative to the turned web strand can make relatively imprecise, so that, for example, images that extend over the entire width of the superpanorama, at the junctions of the outer edges "jumps" have can, which is an unpleasant phenomenon for the viewer or reader.

It is therefore an object of the present invention to provide an improved method for producing an overprinted printed product.

This object is solved by the features of independent claim 1.

For this purpose, the invention proposes a method for producing a printed product in a web-fed printing press with at least one printing unit, comprising the following steps: providing a printing material web; Printing the substrate web in the printing unit; Slitting the substrate web into a first web strand having first and second longitudinal regions and at least one or more further web strands each having first and second longitudinal regions; Superimposing the first web strand and the at least one or more further web strands into a total web strand; Aligning the first longitudinal region of the first web strand with the first longitudinal region of the at least one or more further web strands, wherein the alignment is performed by means of a control device in the width direction of the web strands such that the longitudinal regions are superimposed in a precisely predetermined relation to each other, wherein the longitudinal regions are each arranged along a web strand longitudinal direction; cohesively connecting the respective longitudinal areas with each other; and guiding the thus superimposed and interconnected web strands via at least one former, to perform a longitudinal fold on the entire web strand; wherein the step of slitting the substrate web into the first web strand and the at least one or more further web strands prior to the step of superposing the first webstring and the at least one or more further web strands to the overall web strand is done to facilitate the registration of the web To perform longitudinal areas in the exactly predetermined relation to each other by means of the control device in the width direction, and before the step of the material-locking connection of the respective longitudinal areas is carried out together.

It is advantageous that by slitting the substrate web into the first web strand and the at least one or more further web strands before the step of superimposing the first web strand and the at least one or more further web strands to the total web strand by the subsequent step of superimposing For example, by means of a turning unit with the possibility of side register adjustment, a relatively accurate lateral alignment of the individual web strands to one another, d. H. according to a precisely predetermined relation, can be made so that it can not lead to unwanted jumps in the representation of a picture.

Advantageously, the cohesive bonding, which z. B. can be performed by an adhesive device known in the art, instead of edge regions or outer edges of the web strands, so that a particularly large width of the newspaper thus produced can be achieved.

In a further embodiment, one or more additional web strands or sides can be glued on only one side of the first web strand or of the base web strand, wherein the widths of the glued sides can be the same or different.

In a further embodiment, any number of sides in the same or different widths can be glued on both sides of the base web strand, wherein either all sides are glued together at an edge region of the base web strand or the sides are connected one after the other in the manner of a concertina continuously.

In another embodiment, the alignment and cohesive bonding can also be made at arbitrary locations along the web strand longitudinal direction, so that within the regular width of the newspaper one or more additional pages are hinged.

The invention will be explained in more detail with reference to figures. Here shows or show:

1a shows a schematic side view of a part of a web printing press 1 in which the method according to the invention is executable, wherein a printing material web 10 , a turning unit 15 , an adhesive device 20 as well as a former 25 are shown. The printing material web 10 is printed in a conventional manner in one or more printing units, not shown, and then a first longitudinal cutting device 30 fed where the train 10 is cut longitudinally in the middle. At the same time, the train 10 , as in 1b can be seen, with a second longitudinal cutting device 35 slightly offset with respect to the track 10 central longitudinal cutting device 30 cut longitudinally, leaving the original path 10 a first track 40 , as well as two more railway lines 45 and 50 be produced, the web strands 45 and 50 each half as wide as the track 40 , Of course, in addition to the first and second slitter 30 . 35 still further longitudinal cutting devices conceivable, which in the longitudinal direction of the web 10 are arranged at a substantially same position, wherein each longitudinal cutting device transversely to the longitudinal direction of the web 10 is displaceable, so different width strands of the original train 10 to cut.

Continue with reference to 1a goes through the track 40 now the turning unit 15 while the web strands 45 . 50 walk straight ahead. Through the turning unit 15 become the web strands 40 . 45 . 50 superimposed, wherein by the turning unit 15 a correction of the side register of the web track 40 can be made, so that, for example, the outer edges of the web strand 40 exactly with the outer edges of the web strands 45 and 50 can be aligned. In addition, as is common in the art, a cutting register of the web strand 40 by means of a cutting register adjustment device 55 be set.

Next, as in 1a can be seen by means of an adhesive device 20 the bonding of the exactly aligned edge regions or outer edges of the web strands, which in the 1a and 1b each with adhesive traces 60 . 65 is indicated.

Next, the thus glued total web strand is on the former 25 guided, wherein the total web strand is folded in the middle, as in 1b is indicated with a schematic representation of a printed product D thus produced.

As in 1b It can be seen next to the former 25 yet another former or even several other formers are arranged, as is known in the art.

In 1b It can also be seen that the turning unit 15 two turning bars 70 . 75 includes, wherein the turning bar 75 transversely to the web longitudinal direction is displaced, which by arrows 80 . 80 is indicated. Thus, the above-mentioned adjustment of the side register of the web can be made 40 relative to the railway lines 45 . 50 and thus achieve the exact alignment of the webs to each other.

In the 2a and 2 B again show schematic views of a web printing press 1 in a side view ( 2a ) or in a plan view ( 2 B ), whereby here too the inventive method on the web printing machine 1 is executable. Here, the same reference numerals as in the 1a and 1b used.

Unlike the 1a and 1b is in the 2a and 2 B the case shown that this time the - narrower - web strands 45 . 50 through the turning unit 15 be guided to a Seitenregisterverstellung relative to the web strand 40 perform. This will be the web strands 45 . 50 turned separately, what in 2a it can be seen that the web strands 45 . 50 above or below the track 40 run.

In 2a It can also be seen that next to the glueing device 20 still an additional gluing device 21 is arranged, as the web strands 45 . 50 on different sides of the track 40 run, ie above and below the track 40 as mentioned above. Thus, the printed product D in 2 B different in the sense that the extra pages, according to the web strands 45 . 50 , open in the opposite direction.

In the further figures, various print products which can be produced by the method according to the invention are now shown, which only differ in their production method in that the number of web strands is different and the type of bonding or folding. For each figure, three representations are shown in a sequence from left to right, on the left side of the situation is shown, when the total web strand is passed over a former, and wherein in the middle or on the right side of each figure the finished Printed product D is shown in different Aufklappstellungen.

This total track strand from first track 40 and attached to it strand of railway 45 is over a funnel 25 guided, so that as a result, the printed product D is generated, as in 3a Middle and right can be seen.

3b shows a situation where the railway line 45 on one side of the track 40 is arranged, by the former 25 is averted, so that the aufklappende side on the back of the track 40 or, if you like, on the back of the newspaper.

3c and 3d show similar situations as in the 3a and 3b , with the difference that the web track 45 each at a second longitudinal area 42 of the railway line 40 is glued or is.

4a and 4b show situations where both the first longitudinal area 41 as well as at the second longitudinal area 42 of the railway line 40 web strands 45 and 50 are glued, the web strands 45 . 50 in 4a the funnel 25 are facing, and in 4b arranged on the side of the web track, the funnel 25 turned away.

5 shows a situation where only at one edge region of the web track 40 the web strands 45 . 50 are glued, the web strand 45 on the railway line 40 is glued, and webbing 50 to railway line 45 is glued on.

6a shows a situation similar to the one in 5 shown situation, however, at both edge regions of the web strand 40 two train tracks each as in the in 5 glued to the situation shown.

6b shows a situation where on one side of the track 40 a track is glued, and on the other side of the track 40 two web strands are glued.

7a shows a situation where a total of four web cords on each side of the track 40 are glued, similar to the one in 6a shown situation.

7b shows a situation similar to the one in 6a shown situation, however with the Difference that the adhered to one side of the web strand web strands have different widths.

7c shows a situation similar to the one in 7b shown situation, but with the difference that an adhered web strand on one side has a different width from the other adhered web strands.

8a to 8c show situations where several web strands each with their first edge regions at one and the other edge region of the web strand 40 are glued, wherein the widths of the adhered web strands can be the same ( 8c ) or different ( 8b and 8c ).

9a to 9c such as 10a to 10c each show situations where an adhesion of an additional web strand or several additional web strands to a first web strand 40 not at an edge area of the track 40 takes place, but at any longitudinal region along the longitudinal direction of the web strand 40 , this longitudinal region being from a center of the web strand 40 can be offset ( 9a to 9c ) or exactly in the middle of the track 40 can be arranged ( 10a to 10c ).

Finally show 11a to 11c Printed products that are produced in tabloid format, in contrast to the printed products in broadsheet format shown in the previous figures, so that additional pages are opened upwards and / or downwards.
