Definitions

• the invention relates to a method for producing a printed product, a further processing device and a system for producing printed products according to the preamble of claim 1, 3 or 4.
• DE 43 25725 C2 shows a web-fed rotary printing press with a warm air dryer and cooling rollers, in which the web is rolled up again after printing.
• the invention has for its object to provide a method for producing a printed product, a further processing device and a system for producing printed products.
• the method according to the invention achieves a very high degree of production flexibility.
• the method allows 100% of the processing speed achievable in the web printing machine to be used, regardless of the working speed of the separating device. It is also very simple with the method according to the invention to produce printed products that are made from different parts are put together, for example one of which can be produced in a large edition and can be arbitrarily combined with at least a second part, of which different versions are produced with a smaller edition
• a printing system for newspaper or commercial printing is subdivided into a web printing machine with an unwinder and one or more printing units for printing on a web unrolled by a reel and a rewinder for rolling up the web after passage through the printing units, and a separating device, in which a dispenser is directly connected to the input of an assembly A web printed in the web printing machine is fed as a roll to the separating device
• the printing of the web and the separating are so independent of each other, they can be at different times, in different locations and / or with different Speeds take place
• FIG. 1 is a schematic side view of a web printing machine according to the invention
• FIG. 2 shows a side view of a separating device according to the invention
• the first assembly of the printing press from FIG. 1 is an unwinder 01, here an Roll changer 01, to which material rolls 02 to be printed, in particular paper rolls 02, are conveyed with the aid of transport carriages 03, which run on rails laid under the floor of a hall in which the printing press is installed.
• the material web 04, in particular paper web 04, which is delivered by the unwinder 01 first passes through a feed mechanism 06, the task of which is to feed the web 04 to subsequent processing assemblies with a well-defined tension that is the same over the width of the web 04 and is unchangeable over time.
• These subsequent assemblies are initially a plurality of printing units 07, each of which prints the front and back of the web 04 with a color.
• 1 shows offset printing units, but other printing techniques can also be used.
• the printing press is designed as a newspaper (i.e. several printing plates are arranged next to one another in the axial direction of the forme cylinder) or a commercial printing press (i.e. for example a single printing plate is arranged in the axial direction of the forme cylinder).
• a total of five printing units 07 are provided for four printing inks and black, not all of which are shown in the figure.
• the paper web 04 passes through a dryer 08 for drying the colors freshly printed on the web 04.
• the paper web 04 emerging hot from the dryer 08 is guided through a cooling roller arrangement 09.
• the dryer 08 and the cooling roller arrangement 09 are required in particular if the printing press (among other things) is to be used for commercial printing on coated paper with low suction capacity; if the printing press is only intended for newspaper printing, in which absorbent papers are generally used, the dryer 08 can also be omitted.
• the last assembly of the printing press forms a reel 11 on which the finished processed web 04 is wound up again into a roll 12.
• the rewound reel 12 is removed from the reel-up 11 and transported away, thus producing a plurality of printed reels 12. These are preferably produced with a single printing press. In another variant, however, it is possible to use printed rolls of several printing machines for the production.
• the printed rolls 12 are processed further on the separating device shown in FIGS. 2 and 3.
• this comprises at least one unwinder 13, which can be identical in construction to the unwinder 01 from FIG. 1.
• two dispensers 13a and 13b are present; Depending on the number of pages of the printed product to be produced, larger numbers of unwinders 13 on a separating device can also be considered.
• the web running direction of the roll changer 01 of the roll printing machine and the roll changer 13a; 13b of the further processing device runs in parallel.
• This dispenser 13a; 13b are each provided with web rolls 12a; 1 b loaded. This can affect the web rolls 12a; 12b are rollers 12 which have arisen at different times on the printing machine of FIG. 1. That is, unlike a conventional coherent printing system, in which If webs printed in different printing units are brought together at the same time and fed together to a singling device, a feeding speed of the webs in the singling device which is only half as large as the feeding speed in the printing press is sufficient to separate their entire production under one (not including changeover times) Viewed from another point of view, the subdivision into the printing machine and processing device makes it possible to produce printed products assembled from several printed webs without having to have printing units available for each of these webs at the same time. It is obvious that in this way a very flexible production with low investment costs is possible
• the unwinders 13a, 13b are each followed by feed mechanisms 14a, 14b, which can be identical in construction to the feed mechanism 06 of the printing press.
• the printed webs 16a, 16b which are voltage-controlled in the feed mechanism 14a or 14b, are fed to a superstructure 17, at the input of which rotating knives 18a, 18b lengthwise into several partial webs 19a, 19b.
• the web 16a is divided into two partial webs 19a and the web 16b into three partial webs 19b, the width of which is assumed from four sides when the original webs 16a, 16b are assumed to be wide z 2.2 and 2.1, 1 pages can be one page corresponds, for example, each to a newspaper page.
• a turning bar arrangement 21 serves to mix the partial webs 19a, 19b
• the partial webs 19a, 19b mixed in the turning bar arrangement 21 are distributed over two folders 22, 23, one of which, as can best be seen in the top view of FIG. 3, centered on the uncut original printed webs 16a, 16b is equipped over the entire web width of the former 24 and the second folder 23 has two former 26 with half the width of the former 24, each of which is centered on the partial webs 19a, 19b formed by central longitudinal dividing of the web 16a or 16b Folders 22; 23 finally, the partial webs are joined to the finished printed products by cross cutting and cross folding and laid out on a conveyor belt 27.
• a sheet delivery 28 is also shown in the figure, to which a web or partial web can be fed in order to cut it transversely therein and to lay it out on a stack 29 in the form of individual unfolded sheets.
• the printing machine of FIG. 1 and the separating device of FIGS. 2 and 3 will be set up in close spatial proximity in order to facilitate the transport paths of the printed rolls 12 from the reel-up 11 of the printing machine to the unwinders 13a; 13b to keep the separating device short.
• Web press and finishing device are e.g. B. arranged in a common building. However, this is not necessary. So it is e.g. conceivable to deliver printed rolls from printing plants at different locations for separation to a central location in order to carry out the separation there. It is thus possible to have different parts of a uniform print job printed at different locations and to combine them into the finished printed product only at the central location of the separating device. This allows several printers to pool their capacity to handle jobs that exceed the capacity of a single one of them, or to utilize remaining capacity by taking on partial orders and thus achieving a high level of utilization of their presses.
• the configuration of the separating device shown in FIGS. 2 and 3 permits the production of up to 32-page printed products if two rolls 16a; each printed with a 16-page printing machine; 16b are joined and separated.
• the number of dispensers and thus the number of printed rolls that can be processed at the same time could easily be increased, e.g. Produce 48- or 64-page products (from three or four webs).
• the printing of the web and the separation into individual printed products are independent of one another through the invention; they can take place at different times, in different places and / or at different speeds.
• the processing line can e.g. B. by coating units, perforating units, dams, card gluing systems, gluing, and variable gravure folders.
