Sub-products are separated from the interconnected strands by cutting transversely to an advancement direction (A) of the web. The sub-products are stacked to form a stack, and are connected with each other during stacking or following stacking. The sub-products are folded individually or as a stack about a folding line that runs between adjacent printed portions of a printed sheet. Independent claims are also included for the following: (1) a device for producing multi-leaf, folded printed products (2) a multi-leaf, folded printed product comprising sub-products.

Description

The present invention relates to a method and an apparatus for producing multi-leaved, folded printed products, especially magazines and brochures, according to the preamble of claim 1 and of claim 9, as well as a produced according to the inventive method multi-leaved, folded printed product.

In the production of printed matter such as magazines, brochures, booklets and the like. In digital printing, the pages of a printed product are printed one after the other. Only when all pages of a product have been printed does printing of the next product begin.

With the digital printers available so far, with which material webs with a web width of up to 50 cm can be printed, it is possible to produce two pages of the same product in the production of DIN A4 (or 81/2 x 11 inch) printed products , which run with their long side parallel to the longitudinal extent of the material web to print next to each other (so-called double-use). But there are already digital printing machines used that can print webs with a width of 67 cm. With such digital printing machines, three pages of the same product can be printed next to each other (triple benefit) for printed products in the above-mentioned DIN A4 format.

The present invention is based on the object, starting from a printed in a digital printing material web, which is printed with three and more juxtaposed pages of a printed product, in the simplest possible and time-saving manner and thus produce inexpensive finished printed products.

This object is achieved according to the invention by a method having the features of claim 1 and by a device having the features of claim 9. The printed product produced in the manner according to the invention is characterized by the features of claim 15 and claim 16, respectively.

The production of a folded end product starting from a material web with three and more printed material web sections arranged next to one another proceeds in a simple manner as follows:

In a first step, when the material web advances, a first material web strand is brought together with a second material web strand and joined to the latter along a connecting line extending in the longitudinal direction of the material web in the region of a later fold line by means of an adhesive. The merging of the web strands can be carried out in various ways, but preferably as defined in claims 5 and 6.

In a second step, partial products are continuously separated from the two interconnected and moving material web strands by transverse cutting. These partial products are stacked in a third step to a stack. At the Stacking or after stacking, the partial products are joined together in a fourth step.

In a fifth step, the partial products are treated individually, i. before stacking, or folded as a stack.

In a corresponding manner, end products can also be produced from a printed material web which has four printed material web sections arranged next to one another.

Other preferred further developments of the inventive method and the inventive device form the subject of the other dependent claims.

A first embodiment of the method according to the invention will now be explained with reference to the figures.

The printed in a digital printing station web 1 has three juxtaposed, printed material web sections 2, 3 and 4 of the same width. In the FIG. 1a is the demarcation between the material web sections 2, 3 by dotted lines 5, 6, which extend in the longitudinal direction of the web 1, indicated. Each material web section 2, 3, 4 is printed with successive pages of a printed product, wherein in each case 3 sides a, b, c or d, e, f are arranged with their longitudinal sides running parallel to the longitudinal direction of the material web 1 side by side. The delimitation between the individual sides of each web strand 2, 3, 4 in the longitudinal direction of the web 1 is indicated by dotted lines 7, 8 and 9 respectively.

The material web 1 coming from the digital printing station is moved forward in the direction of the arrow A which extends in the longitudinal direction of the material web 1. During this forward movement, a first material web strand 10 formed by the material web section 4 is folded around a line 12 parallel to the feed direction A, which coincides with the delimitation line 6, against a second material web strand 11, which is formed by the two other material web sections 2 and 3, like that by the arrow B in FIG. 1a is indicated. The second material web strand 11 is twice as wide as the first material web strand 10. Before the material web strand 10 is folded over, the material web 1 is perforated along the fold line 12, as shown in FIG FIG. 1a by the only schematically illustrated perforating tool 13 is indicated. This perforation, which serves as a preparation for later folding, can also be omitted.

To connect the material web strands 10 and 11 guided together in this way, an adhesive is applied in the longitudinal direction of the material web 1 in the region of the center line of the material web strand 11, ie in the region of the delimitation line 5, to the second material web strand 11, as in FIG FIG. 1a indicated by the arrow C. In the FIG. 2 is shown in front view, the material web 1 with the two interconnected web strands 10, 11, wherein the adhesive connection with 14 and the folded edge is denoted by 12a.

From the advancing in the feed direction A further material web 1 with the folded against the second material web strand 11 and bonded to the latter first web strand 10 (FIG. FIG. 1b In a next step, partial products 15 are continuously separated along a line running transversely to the feed direction A, as shown in FIG Figure 1c symbolized by the scissors 16. Each sub-product 15 consists of a first, separated from the first web strand 10, printed sheet 17 and a second, separated from the second web strand 11, printed sheet 18. The two sheets 17 and 18 are bonded together in the region of a center line 19 of the second sheet 18.

These subproducts 15 ( Figure 1d ) are then aligned with their folding edges 12a to one another in Figure 1e schematically illustrated stack 20 placed on each other. In this case, each partial product 15 is connected by means of an adhesive with the previously placed on the stack 20 partial product 15 in the region of the center line 19 of the second sheet 18, which coincides with the longitudinal center line of the wider web strand 11 and the later fold line. The application of an adhesive to the second sheet 18 is in Figure 1e indicated by the arrow D. In the FIG. 3 are shown in front view of the stack 20 superimposed partial products 15, wherein the adhesive connection between the partial products 15 is designated 21.

In the subsequent method step, the stacked partial products 15 are folded along a fold line 22 coinciding with the center line 19 of the second sheet 18 to form an end product 23, as shown in FIG FIG. 1f is indicated by the arrow E. In FIG. 4 is shown in front view of the folded end product 23, the folded edge is denoted by 24.

Like in the Figure 1g Finally, the end product 23 is shown cut to the side edges 23a, 23b adjoining the fold edge 24 and to the side edge 23c lying opposite the fold edge 24. In this case, at these side edges 23a-c edge portions 25, 25 ', 25''cut away, as symbolized by the scissors 26.

The cutting away of the edge portions 25 and 25 'can be omitted under certain circumstances, for example, when the quality of the final product 23 is not too high demands.

With reference to the Figures 5 bis7, the representation of the FIGS. 2 to 4 Now, a variant of the method, which is described above with reference to the FIG. 1 has been described.

In this variant, the folding of the first strip of material strip 10 and the bonding of the latter with the second material web strand 11 takes place as in the case of the hand FIG. 1 described method. Therefore, the FIG. 5 with the FIG. 2 identical. Also, the separation of partial products 15 according to the Figures 1c and 1d and the stacking of the partial products 15 to a stack 20 takes place in the manner already described.

Unlike at the hand of the FIG. 1 described method in this variant, the partial products 15 when stacked to stack 20 are not connected to each other, that is, the application of an adhesive between the superposed partial products 15 and thus the adhesive connection 21 accounts. This is from the FIG. 6 the remainder of the FIG. 3 equivalent.

The superimposed partial products 15 are folded around a fold line 22 to a final product 23 ', wherein the stacked partial products 15 before or after folding along the fold line 22 and the folding edge 24 are connected together in an appropriate manner, preferably by stitching. The FIG. 7 , the the FIG. 4 shows, in front view, the folded and stapled end product 23 ', wherein the schematically illustrated stitching connection is denoted by 27.

The final product 23 'can, as on hand of the Figure 1e be trimmed if necessary at the margins.

Below we at the hand of the FIG. 8 that in the representation of the FIG. 1 corresponds, a second embodiment of the inventive method explained.

This second embodiment differs from the first embodiment according to FIG. 1 by a different way of bringing together the two web strands 10 and 11. Therefore, for themselves corresponding features and parts in the FIG. 8 and the associated FIGS. 9 to 11 the same reference numerals as in the FIGS. 1 to 7 , In the description of this second embodiment is always on the description of the FIGS. 1 to 7 Referenced.

During the forward movement of the printed material web 1 coming from a digital printing station, the first, narrower material web strand 10 is not folded over against the second material web strand 11 as in the first embodiment, but along a cutting line 28 which runs parallel to the feed direction A and coincides with the delimitation line 6. separated from the second web strand 11, as in the FIG. 8a symbolized by the pair of scissors 29. Subsequently, the cut material web strand 10 is placed on the second web strand 11, that the two web strands 10 and 11 along one of its longitudinal edges 10 a, 11 a aligned with each other, as in FIG. 8a indicated by the arrow F. simultaneously is the first web strand 10 - same as in the first embodiment - along its other longitudinal edge 10 b connected by means of an adhesive to the second web strand 11. The application of the adhesive to the second material web strand in the longitudinal direction of the material web 1 in the region of the center line of the second material web strand 11, ie in the region of the delimitation line 5, is indicated by the arrow C.

The others, in the FIGS. 8b to 8g illustrated method steps, namely the separation of partial products 15 of the material web 1 with the second material web strand 11 and laid with this associated first web strand 10 (FIG. FIGS. 8b to 8d ), the stacking of the partial products 15 to a stack 20 (FIG. FIG. 8e ), the folding of the stacked partial products 15 along a fold line 22 to an end product 23 (FIG. FIG. 8f ) and the trimming of the final product 23 at the side edges 23a, 23b, 23c ( Figure 8g ) takes place in the same manner as in the first embodiment. It is therefore based on the corresponding explanations in the description of the method FIG. 1 directed. It should be noted, however, that the trimming of the final product 23 at the side edges 23a and 23b is generally no longer necessary, as one of these side edges 23a, 23b passes through a portion of one longitudinal edge of the web 1 and the other side edge through a portion of the cut edge 28 is formed.

The in the FIG. 9 shown in front view of material web 1 with superimposed and interconnected web strands 10, 11 differs from the in of the FIG. 2 shown material web 1 only in that the web strands 10, 11 are not connected to each other at their mutually aligned longitudinal edges 10a, 11a. The same applies to the in the FIG. 10 shown stacked partial products 15 and the final product 23 according to FIG. 11 ,

Based on FIGS. 12 to 14 that in the presentation the FIGS. 9 to 11 will now be a variant of the second embodiment of the inventive method according to FIG. 8 explained.

This variant corresponds to the variant according to the FIGS. 5 to 7 , That means that in the in the FIGS. 12 to 14 shown variant, the partial products 15 are not connected to each other when superimposed and thus the adhesive connection 21 is omitted. For this purpose, the stacked partial products 15 are joined together before or after folding along the folded edge 24, preferably by stitching. This booklet connection is in the FIG. 14 same as in the FIG. 7 denoted by 27.

Based on FIG. 15 An apparatus for carrying out the method according to the invention (first and second embodiments) will now be described.

In the FIG. 15 is shown purely schematically and in plan view, a processing line 30 having an unwinding station 31 for unwinding the web to be printed from a roll. This unwinding station 31 can be, for example, an unwinding module UW 6 distributed by the applicant. The unwind station 31 is a digital printing station 32 downstream. The material web printed in this digital printing station 32 is fed to a merging station 33, in which the web strands 10, 11 are brought together and connected to one another by means of an adhesive. For carrying out the first embodiment of the inventive method according to FIG. 1 the merging station 33 may be a longitudinal folding station of known type. For carrying out the second embodiment of the inventive method according to FIG. 8 the Zusammenführstation 33 is a processing unit for separating the first web strand 10 from the second web strand 11 and then superimposing the two web strands 10, 11, as sold for example by the applicant under the name "Bahnmerger WM6-Even". However, it is also possible to use a combined processing station as the merging station 33, which optionally brings together the material web strands 10, 11 according to the first embodiment or according to the second embodiment. Such a combined processing station is the subject of European patent application no. 08 009 232.2 dated May 20, 2008 and is sold by the assignee under the name "Folder-Merger FM6". Each embodiment of the merging station 33 is equipped with a device for connecting the two material web strands 10, 11 along a connecting line by means of an adhesive.

The merging station 33 is followed by a cross cutting station 34 for separating the partial products 15. As one such cross-cutting station 34 is suitable for the cross-cutting module CS6-I marketed by the applicant.

The cross-cutting station 34 leaving partial products 15 are placed in a stacking station 35 to a stack 20 each other. As a stacking station 35 is particularly suitable in the EP-A-1 471 022 described collection device, which is sold by the applicant under the name "Drum Collector DC7". For carrying out the inventive method according to the FIGS. 1 and 8th the stacking station 35 is equipped with a device for applying an adhesive to the respective uppermost sub-product 15 in the stack 20 in the region of the later folding line.

The stacked in the stacking station 35 partial products 15 are folded in a folding station 36 to a final product 23. For the folding station 36, for example, in the EP-B-1 213 245 described folding device or a knife folding ZK500, the company Griesser & Kunzmann GmbH & CO. KG in Wellendingen (Federal Republic of Germany).

The folding station 36 is adjoined by a side edge cutting station 37 in which the folded end products 23 are cut at the side edges 23a, 23b and 23c. This side edge cutting station 37 may be omitted under certain circumstances.

The finished end products 23 are transferred to a removal module 38 at the end of the processing line 30.

For carrying out the variant of the first and second embodiment of the process according to the invention, the process described in US Pat FIG. 15 shown processing line 30 supplemented by a stitching station, which is arranged for example between the folding station 36 and the side edge cutting station 37.

If the material web 1 is printed in the digital printing station 32 so that 4 printed material web sections are arranged next to one another, then the production of end products takes place in a manner similar to that described above. In contrast to the hand of the FIGS. 1 to 14 described embodiments, while the two together run material web strands have the same width and each consist of two juxtaposed, printed material web sections. The partial products produced in the manner described then consist of a folded, outer, printed sheet and arranged inside the outer sheet, folded, inside, printed sheet. The two sheets are connected to each other by means of an adhesive in the region of the folded edge of the outer sheet.

Hereinafter, a third, not shown in the figures embodiment of the subject invention is described, in which the stacking of the partial products 15 and connecting them together differently than in the embodiments according to the FIGS. 1 and 8th he follows. In this third embodiment are based on the Figures 1a-1d or 8a-8d described manner partial products 15 prepared. These partial products 15 are then folded in the manner of a saddle roof along the center line of the sheet 18 and then astride into a stack superimposed. For bonding the partial products 15 together, an adhesive is applied to the inner or outer side along the fold line coinciding with the center line 18 before the sub-products 15 are superposed on one another. The adhesive can be applied continuously or only partially. Such a superimposition and bonding of partial products by means of adhesive is eg in the WO-A-2005/072980 described in detail.

In a variant of this third embodiment, the bonding of the superimposed partial products instead of by means of an applied before or during stacking of the partial products adhesive can be done by stitching the superimposed partial products along the fold line.
