Abstract

A product includes at least one part product in broadsheet format and at least one part product in tabloid format. The length of the tabloid part product is not equal to the width of the broadsheet part product. One of the parts products may have a side overlap relative to the other. The length of the tabloid part product is significantly greater than the width of the broadsheet part product.

Description

The invention relates to devices for producing a printed product according to the preamble of claim 1 or 3.

By the DE 198 03 809 A1 a printing unit is known, which is used in an embodiment for the production of printed products in broadsheet format and in an alternative embodiment for the production of printed products in tabloid format.

The EP 0 111 170 B1 discloses a printed product and a method of making the same, wherein a sheet of a product made up of a plurality of superimposed sheets is to laterally project beyond the others with an edge strip. This serves to simplify the mechanical opening of the product and is cut away at the end of production.

In the EP 1 037 749 B1 is a printed product disclosed, which also has narrower printed pages in the overall product in addition to printed pages with the original external dimensions. This serves to avoid "filling pages" and is achieved, for example, by the fact that the narrower sides of the entire surface of the product can be varied continuously. This can be applied to a broadsheet product, a tabloid product, a magazine product.

By the DE 100 03 025 C1 a Längsfalzeinheit is disclosed for longitudinal folding of different widths of paper webs, wherein the former, together with the associated folding rollers, the funnel inlet roller and the longitudinal cutting device in a frame is displaceable transversely to the web running direction.

The US 2,169,932 A discloses printed products, in particular newspapers in tabloid format or in the full newspaper format, the finished product containing one or more supplements whose edge is visibly protruding from the rest of the product format and containing information, for. B. to the content of the supplement, is printed.

Of the DE 25 26 921 A1 the problem lies in avoiding the finishing of wood-based panels with decorative coatings waste of the printed coating material, which results from the different required dimensions of the plates to be coated. This problem is solved in that a plurality of print image carriers each having the desired width are arranged side by side on a support body.

The DE 102 45 321 A1 discloses a forme cylinder, wherein two pressure sides of different height are arranged in the circumferential direction one behind the other. One of the two printed pages has a control strip in addition to the benefit. Such pairings of two different printed page lengths can be arranged side by side multiple times on the forme cylinder.

The invention has for its object to provide devices for producing a printed product, which consists of partial products of different formats.

The object is achieved by the features of claim 1 or 3.

The achievable with the present invention consist in particular in the fact that a printed product is created, which already provides the viewer in the closed state an increased information content and / or an increased overview of the content. Another advantage is that the finished product is multifunctional designed in such a way that for the consumer partial products of the final product and its content can be seen and removed by the supernatant of one over the other partial product in a simple manner.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

A finished printed product has partial products, wherein at least one of the partial products deliberately has a significant lateral projection Δ. By "significant" is meant that they are not differences due to inaccuracy, by the formation of Falzrücken or for better gripping and subsequent cutting comes off, but that it is aware of a difference, which is greater than 10 mm, z. B. greater than 20 mm, in particular greater than 30 mm, is. It is particularly advantageous if the difference corresponds to at least one height of a text line of the printed protruding sub-product, so that - as indicated in the figures - when summarized product for the viewer, the text line of the supernatant sub-product is recognizable. The finished product is preferably printed in the region of the supernatant at least on one side. In the case of the summarized product, the text line of the protruding sub-product can be recognized laterally for the viewer. The finished product prepares the viewer thus already in the closed state an increased information content and / or an increased overview of the content.

In a first embodiment, the product consists of at least one sub-product in the broadsheet and one sub-product in the tabloid format. In a second embodiment, the final product has two partial products of different tabloid formats, eg. B. two partial products in tabloid formats with different heights, on.

Fig. 1 a) to c) schematically show an example with a device according to Fig. 2 manufactured product. This is characterized by the fact that at least one sub-product ("book") in broadsheet format and at least one sub-product ("book") in tabloid format are summarized in the finished product. The page orientation of tabloid and broadsheet format are perpendicular to each other, resulting in the Fig. 2 . 3 . 4 . 5 and 8th symbolically indicated by a bar symbolizing the title. Here is in Fig. 2 to 5 by way of example in the processing of the page assignment on the web B2; B2 'each a possibly printed line Textes T, z. B- a title T, which protrudes laterally in the finished product shown.

The product ( Fig. 1 ) is characterized in particular by the fact that the length of a Tabloid partial product is unequal to a width of a broadsheet broadsheet product, ie one of the partial products has a lateral projection over the other. In an advantageous embodiment, as in Fig. 1 stated, the length (or side height) of the tabloid partial product significantly larger than the width of the Broadsheed partial product, so that the tabloid partial product after the merging of the relevant strands has a lateral projection (too "significant" so). It is advantageous if the difference corresponds to at least one height of a text line of the printed tabloid sub-product, so that - as in Fig. 1 indicated - for summarized product for the viewer laterally the text line of the tabloid partial product is recognizable.

In principle, the tabloid partial product can have the supernatant on the open longitudinal side of the broadsheet partial product (as shown), but also on the side of the longitudinal fold in the manner described. The latter is advantageous with respect to the page design of the tabloid sub-product, but may require a machine overhead in the production.

In principle, a web-processing machine, in particular a printing machine or its further processing stage (longitudinal cutting device and / or funnel structure), especially for the production of the o. G. Be formed product. However, in a desirable embodiment, the machine and / or further processing stage is designed to be convertible so that either a "normal production" having a homogeneous product shape (eg, only broadsheet or only tabloid partial products) or, if desired, the above-described mixed production of the described Inhomogeneous product can be produced. The following are schematic representations for the selective production of a "normal" - and the mixed product shown.

In Fig. 2 and 3 are in the upper area schematically page assignments of two different widths of material webs B1; B2, z. B. lanes B1; B2, wherein the upper occupancy of an occupancy with six juxtaposed newspaper pages in Broadsheet format. In this way, six printed images are arranged on a form cylinder of a preceding printing unit, not shown, which has at least the length of these six juxtaposed newspaper pages ("three-width" printing press). In normal production, the web B1 is longitudinally cut for further processing in three substantially equal width partial webs, before they follow subsequent formers T1; T2; T3, funnel T1 for short; T2; T3, be fed to the production of Längsfalzen. An effective width of the funnels T1; T2; T3 corresponds to the width of two broadsheet pages. Funnels T1; T2; T3 are preferably arranged side by side in such a way that their funnel tips are respectively aligned with the partial web center.

In order to produce an above-described inhomogeneous product with a supernatant of one of the partial products (here the tabloid partial product) while maintaining the width of the other partial product (here the Broadsheet subproduct), z. B. processes a web B2, which is wider than the six juxtaposed newspaper pages in broadsheet format. Accordingly, in such a machine advantageously the o. G. Form cylinder, or its effective bale length to a corresponding amount, such as. B. at least 20 mm, advantageously at least 40 mm, in particular at least 60 mm wider than it would correspond to the width of the number of broadsheet pages to be printed.

If the supernatant of the tabloid partial product is to be arranged on the side of the fold back of the broadsheet partial product, then at least one of the former T1 should; T2; T3, in particular the folding hopper T1 associated with the tabloid sub-product, can be moved in one direction in such a way that its funnel tip can be selectively brought into a plane E with the other or the other funnel tips in lateral view (FIG. Fig. 6a ). If the funnel tips do not lie in the common plane E, then the folded edges K (folding back for uncut partial strand and "open" folded back for a halved partial strand) are offset by the shifted amount ( Fig. 6b ).

In an advantageous first variant of the first embodiment ( Fig. 2 ) is at least one of the three funnels T1; T2; T3, in particular the hopper T1 lying in alignment with the partial web of the tabloid partial product, transversely to the inlet direction of the web B1; B2 designed to be movable, so that its funnel tip aligned in alignment with the sub-web center of the now broader tabloid sub-product. In addition, the folding hopper T1 associated with the tabloid sub-product can also be variable in its effective width such that it has a smaller width at least on its leg side adjacent to a second former T2 in an operating position for folding broadsheet pages than in an operating position for folding the above-mentioned tabloid pages. This can be realized for example by selectively insertable or removable extension pieces, which are arranged depending on the type of production or removed or folded. In addition, an in Fig. 2 and 3 indicated longitudinal cutting device is provided, which is aligned with the funnel center of the tabloid partial product associated hopper T1.

In an in Fig. 3 set second variant of the first embodiment are three funnels T4; T2; T3 for the pure broadsheet production stationary and executed with a fixed effective width, wherein for the above-mentioned mixed production a separate hopper T1 above (shown), below (not shown) or next to the (not shown) other three hoppers T4; T2; T3 is provided. The partial web (s) having the tabloid format are then guided over the hopper T1, while the sub-webs having the broadsheet pages are passed over the other funnels T4; T2; T3 be led. In this embodiment, the hopper T1 does not have to be variable in width and / or not in position transversely to the web run changeable and / or not designed to be movable in its position along the longitudinal direction of the machine.

As in Fig. 3 indicated, the strand of the tabloid sub-product in different ways around the other funnel T4; T2; T3 or between them be guided through. Depending on the strand guide, a mixed product can be produced, with the tabloid subproduct then lying below (as shown), above or between the broadsheet partial products.

In Fig. 4 are in the upper area schematically page assignments of two different widths webs B1; B2, wherein the upper occupancy corresponds to an occupancy with four juxtaposed newspaper pages in broadsheet format. In this way, four printed images on a form cylinder, not shown, a preceding printing unit are arranged, which has at least the length of these four juxtaposed newspaper pages ("double-width" printing press). In normal production, the web B1 is longitudinally cut for further processing in two substantially equal width partial webs, before they follow subsequent formers T1; T2 are fed to produce Längsfalzen. An effective width of the funnels T1; T2 corresponds to the width of two broadsheet pages. Funnels T1; T2 are preferably arranged side by side in such a way that their funnel tips are in each case aligned with the partial web center.

In order to produce in this embodiment, an above-described inhomogeneous product with a supernatant of one of the partial products (here the tabloid sub-product) while maintaining the width of the other sub-product (here the broadsheet sub-product), is now z. B. processes a web B2, which is wider than the four juxtaposed newspaper pages in broadsheet format. Accordingly, in such a machine advantageously the o. G. Form cylinder, or its effective bale length, again by a corresponding amount, such. B. at least 20 mm, advantageously at least 40 mm, in particular at least 60 mm wider than it would correspond to the width of the number of broadsheet pages to be printed.

For the formation of the funnel T1 regarding its mobility transversely to the web direction and / or the variability of its effective width and / or the mobility of his Point out of the plane E out or into this into the said variant 1 of the first embodiment applies with the difference that no third funnel T3 is required or provided.

Likewise, it may, according to the second variant of the first embodiment, be provided, two -. B. stationary - funnel T4; T2 for pure broadsheet production plus, in addition, an additional, wider funnel T1 below or below it.

In a non-claimed example according to Fig. 5 are in the upper area again schematically page assignments of two different widths of material webs B1 '; B2 ', z. B. lanes B1 '; B2 ', wherein the upper occupancy corresponds to an occupancy with two juxtaposed newspaper pages in broadsheet format. In this way, four printed images on a form cylinder, not shown, a preceding printing unit are arranged, which has at least the length of these two juxtaposed newspaper pages ("simple wide" printing press). In "normal production", z. B. homogeneous production of broadsheet partial products, z. B. at least two such webs B1 'printed by at least two corresponding printing units so and taken together to form a homogeneous product.

Should now be in Fig. 1 set mixed product are created so z. B. at least one above sheet B1 'double broadsheet width printed by a printing unit and at least a second, wider web B2' by a second printing unit, the assignment of two pages side by side in tabloid format also in the unclaimed example of Fig. 5 is shown. The pages in the broadsheet format having web B1 'is now performed on a first funnel T2, which z. B. has an effective width of two broadsheet pages, while the sides of the tabloid-format web 02 'is guided on the hopper T1.

With regard to its movability transversely to the web direction and / or the variability of its effective width and / or the mobility of its tip, the hopper T1 can be formed out of the plane E or into the same as that of the variant 1 of the first embodiment. However, it can just as well with a fixed effective width of at least two Tabloidseitenlängen and / or not transverse to the web B1; B2 movable and / or not be designed with its tip out of the plane E out or into this movable, if it is to be used exclusively for the longitudinal folding of the protruding tabloid sub-products.

The funnel T1 can be arranged above, below or next to the other funnel T2.

In the above examples, a forme cylinder of a printing unit in the axial direction z. At least one printing form, which corresponds to a width of an integral multiple of a width of a newspaper page in broadsheet format, and a printing form, which corresponds to a width of an integer multiple of a length of a printed page in tabloid format on.

For all the above embodiments, in an advantageous embodiment in the strand path of the tabloid partial product, before this strand is combined with one or more of the other strands, a stapler or an adhesive device can be arranged. After the partial strands have been brought together, they can, in an advantageous development, run together into a folding apparatus (not shown) and receive a transverse fold (indicated in the figures by dashed lines, for example).

In Fig. 7 and 8th an embodiment is now shown by way of example, the end product having two partial products of different tabloid formats. Fig. 8 shows one representative Fig. 2 corresponding funnel arrangement. The contents of the Fig. 3 to 6 are on the execution with two tabloid formats (printed pages lying) transfer accordingly.
