Abstract

In a first step, in a printed material web (1) moved in a feed direction, a first material web part (5) which is formed by a material web section (1a) is folded against the rest of the material web (6) that is formed from two material web portions (1b, 1c). In the region of a connecting line (2b) extending between neighbouring material web sections (1b, 1c) the two material web parts (5, 6) are connected to one another by means of a bonding adhesive. In a subsequent step the material web (1) is folded again along a line (2b) extending between two neighbouring material web sections (1b, 1c). All material web sections (1a, 1b, 1c) lie above one another. Subsequently, multi-page sub-products (11), the pages (12a, 12b, 12c) of which are connected to one another in the region of the spine (13) of the sub-product, are separated from the twice-folded material web (1). Finally, the sub-products (11) are placed on top of one another to form a stack (16) and are connected to one another in the region of the spine (13) thereof by means of a bonding adhesive.

Description

Process for producing printed products consisting of at least three partial products

The invention relates to a method for producing from at least three multi-leaflet, superimposed and interconnected partial products existing printed products, in particular books, brochures and the like, according to the preamble of claim 1 and printed products produced by this method.

A method of this type is described in EP 2 145 773 AI. In this known method is based on a material web which has been printed in a digital printing station and which is subdivided into three or four juxtaposed, extending in the longitudinal direction of the material web, printed material web sections. In a first method step, in the case of the material web fed forward in a feed direction, a first material web part, which is formed by at least one of the material web sections, is formed with the remainder, formed from at least one of the other material web sections

Material web part brought together. The two

Material web parts are then connected to each other along a line that runs between two adjacent material web sections by means of an adhesive. Subsequently, partial products are separated from the material web, which are then stacked to form a stack. In stacking, each partial product is bonded by means of an adhesive to the partial product previously placed on the stack. To obtain the existing from the partial products printed product, the folded and interconnected partial products folded around a line that coincides with the center line of the stack consisting of the partial products.

EP 2 159 070 A1 discloses a method for producing book blocks, in which sheets are cut from a material web printed in a digital printing station, which are folded and then stacked to form a stack, which forms a book block in each case. Adhesive is applied to the folded sheets prior to, or when juxtaposed, adjacent to the side edge which is to rest in the spine of the book block. By means of this applied adhesive, the sheets in the stack, i. in the book block, linked together. The book blocks consisting of glued together sheets are finally hung in a cover.

WO 02/40282 A1 describes a process for the production of a final product consisting of printed single sheets. In a first step, in the region of a side edge of the single sheet (single sheets) applied to this two-component adhesive. The individual sheets are then stacked in such a way that the adhesive jobs are superimposed. Subsequently, the stack consisting of individual sheets is pressed in the region of that side edge along which the adhesive jobs are located.

WO 2005/072980 A2 discloses a process for producing bound printed products. In this method, from a material web which has been printed on both sides in a digital printing station, Separate single sheet, which are then prefolded and provided along its fold line with a glue application. Then the sheets are stacked astride a stack. The finished stacks are fed to a further processing station in which the trimmed stacks are stacked into a final product, wherein the individual stacks are connected to one another by means of an adhesive.

The present invention is now based on the object to provide a method of the type mentioned, which makes it possible to produce with the least possible effort and cost finished finished printed products, which consist of several mehrblättrigen, superposed and interconnected partial products. This object is achieved according to the invention by a method having the features of claim 1. A printed product produced by this process is characterized by the features of claim 22.

By various processing operations (folding, separating and stacking of material web sections, application of adhesive) on the advanced web, the various

Web sections so superimposed and connected to each other, that then sub-products can be separated, which consist of several printed sheets, which are connected to each other in the back via a fold or an adhesive compound. The finished printed product is obtained by placing these partial products, which are still trimmed at their side edge opposite the bundle, to one another in a stack and in the region of their Back connected by means of an adhesive.

Preferred further developments of the method according to the invention or of the printed product according to the invention are defined in the dependent claims and described in the description of the figures.

A first exemplary embodiment of the sequence of the method according to the invention will now be explained with reference to FIGS. As FIG. 1 shows, the material web 1 printed on both sides in a digital printing station has three printed images arranged next to one another

Material web sections la, lb, lc the same width. The delimitation between the material web sections 1 a, 1 b and 1 c is indicated by dashed lines 2 a, 2 b extending in the longitudinal direction of the material web 1. Each web portion la, lb, lc is in sheets a, b; c, d or e, f, etc. of a printed product divided. The demarcation between the individual leaves of each Material web section la, lb, lc in the longitudinal direction of the material web 1 is indicated by dashed lines 3a, 3b, 3c, 3d.

With reference to FIG. 2, starting from the material web 1 shown in FIG. 1, a first embodiment of the invention will be described

Production process explained. FIGS. 2a-2e show the individual method steps in front views. The material web 1 coming from the digital printing station is moved forward in the direction of the arrow A (FIG. 1), which extends in the longitudinal direction of the material web 1. As FIG. 2 a shows, an adhesive application 4 (adhesive trace), which may be continuous or interrupted, has been applied to the underside of the material web 1 in the region of the delimitation line 2 b. During the forward movement of the material web 1 is formed by the web portion la first

Material web part 5 to a parallel to the feed direction A extending line 7, which coincides with the delimitation line 2a, folded against a second material web part 6, which is formed by the two other material web sections lb, lc, as indicated by the arrow B in Figure 2b , The second material web part 6 is twice as wide as the first material web part 5. Before the material web part 5 is folded over, if necessary the material web can be perforated along the fold line 7. The resulting from the folding first fold is designated 8. The folded-over material web part 5 becomes in the region of the line 2b at the side opposite the fold 8 side edge 5a by means of the other material web part 6 applied adhesive application 4 with this other material web part 6 is connected (Fig. 2b).

In a second step, the material web section 1c of the other, broader material web part 6 is folded around a line 9 folded parallel to the advancing direction A, which coincides with the delimitation line 2b, against the material web section 1a folded in the first step, as indicated by the arrow C in FIG. 2c is shown. The resulting second fold is designated 10. As FIG. 2c shows, after this two folds of the material web 1, the material web sections 1c, 1c, 1b lie one above the other. From this twice folded material web 1, partial products 11 are then separated in a further step along lines extending at right angles to the feed direction, which coincide with the delimiting lines 3a, 3b, 3c, 3d, etc. (see FIG. 1).

Such a partial product 11 is shown in a front view in FIG. 2d. Each partial product 11 consists of three superimposed sheets 12a, 12b, 12c, of which sheet 12a was a part of the material web portion 1b, the sheet 12b was a part of the material web portion 1a and the sheet 12c was a part of the material web portion lc before separation. At its the back 13, which is formed by the fold 10, opposite side edge 14, the partial products 11 are cut, as shown in Figure 2d by the cutting tool 15 shown purely schematically. In this sub-product 11, the sheets 12a, 12b, 12c in the back 13 are connected to each other, on the one hand on the fold 10 (sheets 12a and 12c) and on the other hand by means of the adhesive of the adhesive application 4 (sheets 12a and 12b). Finally, a plurality of partial products 11, ie, at least three partial products 11 11 ^λ, ^{11, placed} (Figure 2e) to form a stack 16 with each other. In this case, an adhesive is applied to the upper or lower side of the partial products 11 (adhesive application 17) before or during the stacking of the partial products 11, specifically in the region of the side edge lying in the back 13 of the partial products 11. These adhesive applications 17 may be continuous or interrupted or punctiform. FIG. 2e shows a front view of a finished printed product (final product) 18 produced in the manner described above. This printed product 18 is composed of the stacked product parts 11 ^{11, Λ,} ^{Λ Λ} 11 of which each partial product is 11 ^11, 11 ^{Λ Λ} of three sheets 12a, 12b, 12c. These sheets 12a, 12b, 12c are at least for the most part printed on both sides The partial products 11 11 11 are permanently connected to each other in the region of their back 13 by means of the adhesive of the adhesive applications 17. It is understood that 11 ^λ and 11 ^{, ΛΛ} no adhesive is applied to the top of the top or on the underside of the lowest partial product.

The finished printed product 18 does not require further processing more because, as explained on the one hand, the sheets of each partial product 11 11 11 ^{^λ, ΧΛ} and on the other hand the partial products 11 ^{11 λ,} ^11, already interconnected ^λ. The open side edges of the partial products 11 11 ^{, λ} , 11 ^{λ Λ λ} and thus also of the printed product 18 have already been trimmed in the course of the manufacturing process. The stack 16 and thus also the finished printed product 18 can also consist of more than three partial products 11, which are connected to one another as described in the region of their back 13. With reference to FIG. 3, which corresponds in terms of presentation to FIG. 2, a variant of the invention will now be described

Manufacturing method, which has been described above with reference to Figure 2, explained.

This variant according to FIG. 3 differs from the embodiment according to FIG. 2 by a different way of bringing together the two material web parts 5 and 6. Therefore, the same reference numerals are used in FIG. 3 for corresponding features and parts as in FIG. 2. In the variant According to FIG. 3, during the forward movement of the printed material web 1 coming from the digital printing station, the first material web part 5 formed by the material web section 1a is not folded over against the second material web part 6 as in the case of FIG. 2, but along a direction parallel to the feed direction A. Section line which coincides with the delimitation line 2a, separated from the other, second material web part 6, as is symbolized by a pair of scissors 19 in Figure 3a. Subsequently, the cut-away material web part 5 is brought together with the other, second material web part 6, as indicated by the arrow D in FIG. 3b. The bringing together of the material web parts 5, 6 takes place in such a way that the two material web parts 5, 6 are aligned with one another along one of their side edges 5a, 6a and the material web sections lb and la overlap. At the same time, the first web part 5 - same as in the embodiment according to Figure 2 - along its other side edge 5b by means of the adhesive of the adhesive application 4 with the other, second web part 6 is connected (Figure 3b).

If the material web part 5 is to come with its underside to rest against the underside of the other material web part 6, as in the embodiment according to FIG. 2, the severed material web part 5 must be turned before being brought into contact with the other material web part 6. However, such a turning of the material web part 5 can also be omitted.

The further method steps illustrated in FIGS. 3c-e are the same as the method steps described with reference to FIGS. 2c-e. Reference is therefore made to the description of these figures 2c - e.

With reference to FIGS. 4 to 6, which correspond to FIGS. 1 to 3, a second exemplary embodiment of the sequence of the method according to the invention will now be explained.

As shown in FIG. 4, in this exemplary embodiment, a material web 1 printed on both sides in a digital printing station is assumed to have the four printed images arranged side by side

Material web sections la, lb, lc, ld having the same width. The demarcation between the

Material web sections la, lb, lc and ld is indicated by dashed lines 2a, 2b, 2c, which extend in the longitudinal direction of the material web 1. Everyone

Web section la, lb, lc, ld is in sheets a, b; c, d; e, f or g, h, etc. divided a printed product. The delimitation between the individual sheets of each material web section la, lb, lc, ld in the longitudinal direction of the material web 1 is indicated by dashed lines 3a, 3b, 3c, 3d.

Based on the Figure 5, starting from the material web 1 shown in Figure 4, a second embodiment of the inventive

Production process explained. FIGS. 5a-5h show the individual method steps in front views.

The material web 1 coming from the digital printing station is moved forward in the direction of the arrow A (FIG. 4), which extends in the longitudinal direction of the material web 1. As FIG. 5a shows, an adhesive application 4 (adhesive trace), which may be continuous or interrupted, has been applied to the underside of the material web 1 in the region of the delimitation line 2c. During the forward movement of the material web 1, a first material web part 5 formed by the material web sections 1a and 1b is moved around a line 7 parallel to the feed direction A, which coincides with the delimitation line 2b, against a second material web part 6 passing through the two other material web sections 1c, 1c is formed, folded over, as indicated by the arrow B in Figure 5b. The second material web part 6 has the same width as the first material web part 5. Before the material web part 5 is folded over, if necessary, the material web 1 can be perforated along the fold line 7. The resulting from the folding first fold is designated 8. The folded material web part 5 is in the region of the line 2c by means of the other Material web part 6 applied adhesive application 4 with this other material web part 6 is connected (Fig. 5b). The material web 1 once folded in this way with the two material web parts 5, 6 lying one above the other and connected to one another is shown in FIG. 5c.

In a second step, the superimposed material web sections la and ld, each belonging to one of the material web parts 6 and 5, about a parallel to the feed direction A extending line 9, which coincides with the demarcation lines 2a and 2c, against the other two superimposed

Material web sections lb and lc, which each belong to one of the material web parts 6 and 5, folded over, as shown by the arrow C in Figure 5d. The resulting second fold is denoted by 10 (Figure 5e). The material web 1 folded twice in the described manner is shown in FIG. 5e. As can be seen from this figure 5e, lie in this twice folded material web 1, the material web sections ld, la, lb and lc in this order one above the other.

From this twice folded material web 1, partial products 20 are then separated in a further step along lines extending at right angles to the feed direction, which coincide with the delimiting lines 3a, 3b, 3c, etc. (see FIG. 4). Such a partial product 20 is shown in a front view in FIG. 5f. Each sub-product 20 consists of four superposed sheets 21a, 21b, 21c, 21d, of which prior to separation, the sheet 21a part of the web portion lc, the sheet 21b part of the web portion lb, the sheet 21c part of the web portion la and the Sheet 21d part of the Material web section ld was. On its side 22 opposite the back 22, which is formed by the fold 10, the partial products 20 are cut, as shown in FIG. 5f by the cutting tool 15 shown purely schematically.

FIG. 5g shows a trimmed partial product 20 which is open both on its side edge 23 and on the two adjacent side edges running at right angles to the side edge 23. In this sub-product 20, the sheets 21a, 21b, 21c, 21d are connected together in the back 22, on the one hand on the folds 8 and 10 and on the other hand by means of the adhesive of the adhesive application 4th

Finally, a plurality of partial products 20, ie at least three partial products 20 20 20 ^{,, λ} (FIG. 5h), are stacked to form a stack 24. In this case, an adhesive is applied to the upper or lower side of the partial products 20 (adhesive application 25) before or during the stacking of the partial products 20, specifically in the region of the lateral edge located in the back 22 of the partial products 20. These adhesive jobs 25 may be continuous or interrupted or punctiform.

FIG. 5h shows a front view of a finished printed product (final product) 26 produced in the manner described above. This printed product 26 consists of the stacked partial products 20 20 ^λλ , 20 ^λ of which, as already mentioned and shown in Figure 5f each partial product 20 20 ^λ , 20 ^, consists of four leaves 21a, 21b, 21c, 21d, at least for the most part on both sides are printed. The partial products 20 20 ^{, v} , 20 ^{,, λ} are in the region of their back 22 means the adhesive of the adhesive jobs 25 permanently connected. It is understood that is applied on top of the top or on the bottom of the lowermost part of the product 20 'and 20 ^λ no adhesive.

Also in this embodiment, a finished printed product 26 requires no further processing, because as explained on the one hand, the leaves of each sub-product 20 20 20 ^{, Λ} and on the other hand, the partial products 20 20 ^{, λ} , 20 ^{, λ} already connected to each other. The open side edges of the partial products 20 20 ^{, λ} , 20, 10 ^, and thus also of the printed product 26 have already been trimmed in the course of the production process.

The stack 24 and thus also the finished printed product 26 can also consist of more than three partial products 20, which are connected to one another as described in the region of their back 22.

With reference to FIG. 6, which corresponds in terms of presentation to FIG. 5, a variant of the production method which has been described above with reference to FIG. 5 will now be explained.

This variant according to FIG. 6 differs from the embodiment according to FIG. 5 by a different way of bringing together the two material web parts 5 and 6. Therefore, the same reference numerals are used in FIG. 6 as in FIG. 5 for corresponding features and parts.

In the variant according to FIG. 6, during the forward movement of the printed material web 1 coming from the digital printing station, the first, through which Both material web sections la and lb formed material web part 5 is not folded as in the method described with reference to FIG. 5 against the second material web part 6, but along a direction parallel to the feed A cutting line, which coincides with the delimitation line 2b, separated from the other, second web part 6, as which is symbolized by a pair of scissors 19 in FIG. 6a. Subsequently, the cut-away material web part 5 is brought together with the other, second material web part 6, as indicated by the arrow D in FIG. 6b. The bringing together of the material web parts 5, 6 takes place in such a way that the two material web parts 5, 6 are aligned along their side edges 5a, 6a or 5b, 6b and the two material web parts 5 and 6 are congruent to one another (FIG. 6b). At the same time, the first material web part 5 - as in the embodiment according to FIG. 5 - is connected to the other, second material web part 6 by area of the line 2c by means of the adhesive of the adhesive application 4 (FIG. 6c).

The further method steps illustrated in FIGS. 6d-h are the same as the method steps described with reference to FIGS. 5d-h. Reference is therefore made to the description of these figures 5d - h. It should be noted, however, that in FIGS. 6d-h, the sequence of the respective superimposed material web sections 1a-1d is different than that shown in FIGS. 5d-h. If it is also desired in the variant according to FIG. 6 that the material web sections 1b, 1c and 1a, 1d overlap one another as shown in FIG. 5b, then the severed material web part 5 must be brought into contact with the other material web part 6 before joining be turned. However, such a turning of the material web part 5 can also be omitted.

A third exemplary embodiment of the sequence of the method according to the invention will now be explained with reference to FIGS. 7 to 9, which correspond to FIGS. 1 to 3 and 4 to 6.

As FIG. 7 shows, in this exemplary embodiment a web of material 1 printed on both sides in a digital printing station is assumed to have the five printed images arranged side by side

Material web sections la, lb, lc, ld, le has the same width. The demarcation between the

Material web sections la, lb, lc, ld and le is indicated by dashed lines 2a, 2b, 2c, 2d, which extend in the longitudinal direction of the material web 1. Each web portion la, lb, lc, ld, le is in sheets a, b; c, d; e, f; g, h or i, k, etc. divided a printed product. The delimitation between the individual sheets of each material web section 1a, 1b, 1c, 1d, le in the longitudinal direction of the material web 1 is indicated by dashed lines 3a, 3b, 3c, 3d.

With reference to FIG. 8, starting from the material web 1 shown in FIG. 7, a third embodiment of the production method according to the invention will now be explained. FIGS. 8a-8i show the individual method steps in front views.

The material web 1 coming from the digital printing station is moved forward in the direction of the arrow A (FIG. 7), which extends in the longitudinal direction of the material web 1. As the figure 8a shows, is on the bottom of the Material web 1 in the region of the delimitation line 2c, an adhesive application 4 (adhesive trace), which may be continuous or interrupted, has been applied. During the forward movement of the material web 1, a first material web part 5 formed by the material web sections 1a and 1b is moved around a line 7 parallel to the feed direction A, which coincides with the delimitation line 2b, against a second material web part 6 passing through the three other material web sections 1c, 1c , le is folded, folded over, as indicated by the arrow B in Figure 8b. The second material web part 6 is wider than the first material web part 5. Before the material web part 5 is folded over, if necessary, the material web 1 can be perforated along the fold line 7. The resulting from the folding first fold is designated 8. The folded-over material web part 5 is connected in the region of the line 2c by means of the adhesive application 4 applied to the other material web part 6 with this other material web part 6 (FIG. 8b). The material web 1 once folded in this way with the two superimposed web web parts 5, 6 lying one above the other and connected to one another, is shown in FIG. 8c.

As FIG. 8c further shows, the underside of the folded material web part 5, i. on the underside of the material web portion la, in the region of the delimitation line 2a (which is aligned with the line 2c), a further application of adhesive 27 (adhesive trace), which may be continuous or interrupted applied. In a second folding step of the

Material web section le of the wider material web part 6 about a direction parallel to the feed direction A line 9, which coincides with the delimitation line 2d, folded over against the folded in the first folding step material web part 5, as shown by the arrow C in Figure 8d. The resulting second fold is designated 10 (Fig.8e). The folded

Material web portion le is in the region of line 2a at the fold 10 opposite side edge 6a by means of applied to the material web portion la adhesive application 27 with this material web portion la connected (Fig. 8e). The material web 1 folded twice in the manner described is shown in FIG. 8e. As can be seen from this figure 8e, lie in this twice folded web 1 on the one hand, the two web sections lb, lc and on the other hand, the three web sections le, la, ld in this order one above the other.

As is further apparent from FIG. 8e, a third adhesive application 28 (adhesive trace), which may be continuous or interrupted, is applied to the underside of the folded material web section le in the region of its side edge 6a (which is aligned with the delimiting line 2a, 2c).

In a third step, shown in FIG. 8f, the two superimposed web sections lb, lc are moved around a parallel line to the feed direction A line 29, which coincides with the demarcation lines 2a and 2c, against the other three superimposed web sections le, la ld folded, as shown by the arrow E in Figure 8f. The resulting third fold is designated 30 (Figure 8g). From this three times folded material web 1, partial products 31 are then separated in a further step along lines extending at right angles to the feed direction, which coincide with the delimiting lines 3a, 3b, 3c, 3d, etc. (see FIG. 7). Such a partial product 31 is shown in FIG. 8g in a front view. Each sub-product 31 consists of five superimposed sheets 32a, 32b, 32c, 32d, 32e, of which before separation, the sheet 32a part of the web portion ld, the sheet 32b is a part of the web portion la, the sheet 32c part of the web portion le in that the sheet 32d was a part of the web portion 1b and the sheet 32e was a part of the web portion lc. The partial products 31 are cut on their side 33 opposite the back 33, which is formed by the fold 30, as shown in FIG. 8g by the cutting tool 15 shown purely schematically.

FIG. 8h shows a trimmed partial product 31 which is open both on its side edge 34 and on the two adjacent side edges running at right angles to the side edge 34. In this partial product 31, the sheets 32a, 32b, 32c, 32d, 32e are joined together in the back 33, on the one hand via the fold 30 and on the other hand by means of the adhesive of the adhesive applications 4, 27, 28th

Finally, a plurality of partial products 31, ie at least three partial products 31 31, 31 ^λ (FIG. 8i), are stacked to form a stack 35. In this case, an adhesive is applied to this (or glue application 36) before or during the stacking of the partial products 31, specifically in the area of the back products 33 of the partial products 31 lying side edge. These adhesive jobs 36 may be continuous or interrupted or punctiform. As the figure shows 8h, the adhesive on either the top surface (adhesive 36) or also on the underside (adhesive 36 ^λ), the partial products are applied 31st It is understood that on the top of the top or on the bottom of the lowest partial product 31 ^{Λ Λ Λ} or 31 ^λ no adhesive is applied. FIG. 8i shows a front view of a finished printed product (final product) 37 produced in the manner described above. This printed product 37 consists of the stacked partial products 31 31 31 ^{Χ λ} , of which, as already mentioned and shown in Figure 8h, each partial product 31 31 31 ^{, λ} consists of five leaves 32a, 32b, 32c, 32d, 32e, at least the largest Part are printed on both sides. The partial products 31 31, 31 ^, 16 are permanently connected to one another in the region of their back 33 by means of the adhesive of the adhesive applications 36.

Also in this embodiment, a finished printed product requires 37 any further processing more because, as explained on the one hand, the sheets of each partial product 31 31 ^Λ, ^{31, v} and on the other hand, the partial products 31 ^λ, ^{31 λ,} 31 ^{Λ, Λ} are already connected with each other. The open side edges of the partial products 31 ^λ , 31 ^{, λ} , 31 ^{, λ} and thus also of the printed product 37 have already been cut in the course of the manufacturing process.

The stack 35 and thus also the finished printed product 37 may also consist of more than three partial products 31, which described in the region of their back 33 are interconnected exist.

The adhesive jobs 4 and 27 can also be applied at a different location than shown in the region of the demarcation line 2c (adhesive application 4) or in the region of the demarcation line 2a (adhesive application 27). Alternative locations for applying the adhesive for adhesive applications 4 and 27 are shown in Figures 8a-d. As can be seen from FIGS. 8a, 8b, it is also possible to apply the adhesive application 4 in the region of the delimitation line 2a to the underside of the material web section 1b. Such an adhesive application is denoted by 4 ^λ . As shown in FIGS. 8c, 8d, the application of adhesive 27 in the region of the side edge 6a of the material web section le can be applied to the underside of this material web section le. Such a

Adhesive application is denoted by 27 ^λ . It will be understood that it can be applied in another suitable location also in the embodiments that have been described in Figures 2, 3 and 5, 6, the adhesive 4 (described in accordance with the above with reference to Figure 8 an alternative (adhesive 4 ^λ )) *

With reference to FIG. 9, which corresponds in terms of presentation to FIG. 8, a variant of the invention will now be described

Manufacturing method, which has been described above with reference to Figure 8, explained. This variant according to FIG. 9 differs from the embodiment according to FIG. 8 by a different way of bringing together the two material web parts 5 and 6. Therefore, the same reference numerals are used in FIG. 9 for corresponding features and parts as in FIG.

In the variant according to FIG. 9, during the forward movement of the printed material web 1 coming from the digital printing station, the first material web part 5 formed by the two material web sections 1a and 1b is not folded over against the second material web part 6 as in the method described with reference to FIG along a cutting line parallel to the feed direction A, which coincides with the delimitation line 2b, separated from the other, second material web part 6, as is symbolized by a pair of scissors 19 in FIG. Subsequently, the cut-away material web part 5 is brought together with the other, second material web part 6, as indicated by the arrow D in FIG. 9b. The material web parts 5, 6 are brought together so that the two material web parts 5, 6 are aligned along their side edges 5b, 6b and the two material web sections la, lc and lb, ld of the two material web parts 5 and 6 congruently overlap one another (FIG. 9b). , At the same time, the first material web part 5 - same as in the embodiment according to FIG. 8 - is connected to the other, second material web part 6 by area of the line 2c by means of the adhesive of the adhesive application 4 (FIG. 9c).

The further method steps illustrated in FIGS. 9c-i are the same as those with reference to the figures 8c - i described process steps. Reference is therefore made to the description of these figures 8c - i. It should be noted, however, that in FIGS. 9b-9f the sequence of the material web sections lying one above the other is different than that shown in FIGS. 8b-8f. If, in the variant according to FIG. 9, one wishes to overlap the material web sections 1b, 1c and 1a, 1d as well, then the separated material web part 5 must be turned before being brought into contact with the other material web part 6. However, such a turning of the material web part 5 can also be omitted.

It should further be noted that in the variant shown in FIG. 9 the adhesive of the adhesive application 4 is applied to the upper side of the material web section 1b (FIGS. 9a, 9b) and not to the underside of the material web section 1b as shown in FIGS. 8a, 8b.

In a variant of the manufacturing method shown in FIGS. 8 and 9, the first material web part 5 is formed only by the one material web section 1a. This first material web part 5 is then brought together with the other, second material web part 6 as shown in FIGS. 8a, b or 9a, b and connected to this second material web part 6 in the region of the delimitation line 2a or 2b by means of an adhesive application 4. Subsequently, a first, central folding of the second material web part 6 together with the first material web part 15 connected thereto takes place around a fold line coinciding with the delimitation line 2c and then a second, central folding around a fold line coinciding with the delimitation line 2d. The Folded material web sections la - e are as far as necessary connected to each other during the first or second folding by means of an adhesive so that in the finished part product 31 whose leaves 32a - e are connected to each other in the back 33 of this partial product 31.

In an alternative, the separated according to Figure 9a web part 5 (web portion la) with one of the web sections lc, ld or le brought together and connected, as described twice before the folding and bonding takes place by means of the adhesive.

In the manner described with reference to FIGS. 1 - 3, 4 - 6 or 7 - 9, starting from a material web which has 6, 8 or 10 printed material web sections arranged side by side in its longitudinal direction, it is possible to produce partial products which correspond to FIG , 8 or 10 pages printed on both sides and which are stacked as described to finished printed products.

In the following, reference will be made to other variants of the manufacturing method described above.

Instead of the partial products 11, 20, 31 as with reference to Figures 2, 3; 5, 6 and 8, 9 described prior to stacking on their the back 13, 22 and 33 opposite side edge 14, 23 and 34 to trim (front trimming), this front trim can also be done on the finished stack 16, 24 and 35, ie with superimposed partial products 11, 20 and 31. Together with this Frontbeschnitt can also if necessary, the remaining side edges which extend at right angles to the back 13, 22, 33 of the partial products 11, 20, 31, be circumcised. In Figures 2, 3; 5, 6 and 8, 9, the adhesive applications 4, 27, 28 are shown as being adjacent to an associated delineation line 2a, 2b and 2c, respectively, or to the side edge 6a. However, the adhesive applications 4, 27, 28 applied to the material web 1 or its sections la - e may also assume a slightly different position than that shown in the figures with regard to the associated delimitation line. Furthermore, the adhesive of these adhesive applications 4, 27, 28 can be applied to the material web 1 or its parts 5, 6 from below, from above, from the side or in another suitable manner (see FIGS. 8 and 9).

It is understood that in all described embodiments and variants, the web 1 in the digital printing station must be printed so that the printed on the sheets 12a - c, 21a - d, 32a - e of each sub-product 11, 20, 31 pages of the finished printed product 18, 26 and 37 are arranged in the correct order. This is achieved by a corresponding preparation of the print data for the digital printing station.

In all the embodiments shown, the folding of material web parts and sections takes place downwards (i.e. in the direction of the arrows A, B, E). In principle, however, it is also possible to fold over the material web parts and sections upward (counter to the direction of the arrows A, B, E). In this alternative, of course, the adhesive jobs 4, 27, 28 would have to be applied in accordance with other locations.
