The present invention is directed to a method for producing a printed product, to a device for further processing, as well as to an installation for producing printed products. A web of material is taken from a roll, is printed and is then re-rolled. Several re-rolled printed web are then processed further.
DE 43 25 725 C2 shows a web-fed rotary printing press with a hot air dryer and cooling rollers. A] web is rolled up again after having been printed.
DE 198 37 117 A1 describes a method for producing newspapers. Webs which have been imprinted with the editorial contents and with the contents of inserts are wound on assigned rolls. The rolls, which are required for a complete newspaper, are then rolled off again, are combined with other webs and are longitudinally folded.
U.S. Pat. No. 3,948,504 discloses an installation for processing two imprinted webs of material, each of which is rolled off a roll changer. Each one of these webs of material is longitudinally cut and is the conducted over turning bars to the longitudinal former. All longitudinally folded partial webs are transversely cut downstream of the longitudinal former.
The object of the present invention is directed to providing a method for producing a printed product, to providing a device for further processing, as well as to providing an installation for producing printed products.
In accordance with the present invention, this object is attained by printing a material web which has been unwound from a roll and which is re-wound as a new roll after printing. Several previously printed webs can be then unwound and can be further processed. The initial web printing installation and the further processing location can both be in a single building. The previously printed webs can be separated into partial webs.
The advantages to be attained by the present invention consist, in particular, in that a very high degree of production flexibility is achieved by the use of the method of the present invention. The present method permits 100% utilization of the press production speed which can be reached by the web-fed printing press, regardless of the working speed of the separating devices. Also, by the use of the method of the present invention, it is very simple to produce printed products which are put together from different parts, one of which can, for example, be produced in high numbers and which can be arbitrarily combined with at least a second part, of which different versions are produced, each at lower numbers.
A printing installation for printing newspaper or for job printing is divided, on the one hand, into a web-fed printing press with an unreeling device and with one or with several print units for imprinting a web rolled off a roll by operation of the unreeling device, and with a re-reeling device for use in rolling up the web after its passage through the print units. On the other hand, the printing installation also includes a separating device, in which an unreeling device is connected directly with the inlet of a structural component. A web, which was imprinted in the rotary printing press, is supplied to the separating device in the form of a roll. Imprinting of the web and separation of the web become independent of each other in this way; they can take place at different times, in different locations and/or at different speeds.
Preferred embodiments of the present invention are represented in the drawings and will be explained in greater detail in what follows.
Shown are in:
Referring initially to
These subsequent structural processing groups are first a plurality of print units 07, each of which print units 07 imprints the front and back of the web 04 in a color. The schematic representation depicted in
After passing through the print units 07, the paper web 04 passes through a web dryer 08 for the purpose of drying the ink which was freshly imprinted on the web 04. The paper web 04, which is emerging hot from the dryer 08, is then conducted through a cooling roller arrangement 09.
The dryer 08 and the cooling roller arrangement 09 are necessary, particularly in those cases where it is intended to employ the printing press (inter alia) for job-printing of coated paper having little absorption capability. If the printing press is intended for use in newspaper printing only, and wherein paper that is capable of significant absorption is generally employed, the dryer 08 can also be omitted.
The last structural component of the printing press is formed by a reeling device 11, on which the finished, printed web 04 is again rolled up into a roll 12.
In this printing press, there are no transverse cutting and folding devices located in the path of the paper web 04. This means that an important limiting factor of the web running speed, at which the printing press can be operated, does not apply. High production speeds can thus be achieved on this printing press.
Every time the capacity of the reeling device 11 is reached, or a print job has been completed, the rewound roll 12 is removed from the reeling device 11 and is taken away. Several imprinted rolls 12 are generated in this way. In another variation of the present invention, it is possible to employ several printing presses for forming the imprinted rolls.
The imprinted rolls 12 are then further processed in the separating device which is represented schematically in
The web running direction in the roll changers 01 of the web-fed printing press, and the web running direction of the roll changers 13a, 13b in the further processing device extend in parallel.
Each of these unreeling devices 13a, 13b is provided with rolls 12a, 12b of webs which had previously been imprinted in the printing press. The rolls 12a, 12b of previously imprinted webs, which are simultaneously being processed in the separating device, can be rolls 12 which were previously imprinted at different times on the printing press in
Referring again to
The partial webs 19a, 19b, which are mixed in the turning bar arrangement 21, are distributed onto two folders 22, 23. Folder 22, as can best be seen in the top plan view in
A sheet delivery device 28 is also shown in
In general, the printing press shown in
It is also within the scope of the present invention to flexibly produce printed products which consist, such as many daily newspapers do, of a super-regional uniform portion and of regionally specific portions. The super-regional portion is typically printed at a central location, in large editions, while the local portions are each respectively printed at different locations in smaller editions. In accordance with the present invention, it is possible to distribute the rolls with the super-regional portion to the different locations and to combine them there with the regional portions and to make them into individual newspapers of the regional locations.
The configuration of the separating device represented in
The processes or steps of the imprinting of the web, and the separation of the imprinted web into individual printed products become independent of each other by use of the present invention. They can take place at different times, in different locations and/or at different speeds.
The line for further processing can be complemented, for example, by varnishing units, by perforating units, by retaining units, by card-securing adhesive systems, by glue application, as well as by variable rotogravure folding apparatus.
While a preferred embodiment of a method for the production of a printed product, a processing device, and a system for the production of printed products, in accordance with the present invention, have been set forth fully and completely hereinabove, it will be apparent to one of skill in the art that various changes in, for example, the specific structure of the unrolling devices and of the reeling devices, as well as of the printing units, could be made without departing from the true spirit and scope of the present invention which is accordingly to be limited only by the appended claims.
