DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
The present invention relates to a method and to a device for producing multi-layered, for example four-layered, newspaper products with a tabloid section inserted into a newspaper product. At least one longitudinal former is used to produce the multi-layered newspaper products. A number of paper webs can be varied and added to the one or more webs provided to the longitudinal former.
DESCRIPTION OF THE PRIOR ART
With single, i.e. collected, production and using, for example two longitudinal formers, it is known to manufacture printed products which consist of three separate newspaper sections and a separate tabloid section. In this case, the thickness of the tabloid section is determined by the thickness of the newspaper section which is guided over the same longitudinal former, and vice versa. A device for manufacturing such a printed product is disclosed in DE 43 19 806 A1.
U.S. Pat. No. 2,092,977 describes a device and a method for producing multi-layered newspaper products with an inserted tabloid section. Here, all successive products have a tabloid section, since one web is cut completely into two halves by means of a cutting device.
U.S. Pat. No. 2,361,140 and GB-A-437 858 describes longitudinal formers with associated longitudinal cutting devices.
SUMMARY OF THE INVENTION
It is the object of the present invention to provide a method and a device for producing multi-layered newspaper with so-called tabloid sections.
In accordance with the invention, this object is attained by utilization of at least one longitudinal former. A number of paper webs, which number is variable, is admixed to the one or more webs that are provided with a longitudinal separation cut and which are fed to the one longitudinal former.
The advantages which can be achieved with the present invention reside in particular in that the number of pages of the tabloid section enclosed in a layer of a longitudinally folded newspaper section can be varied. In this case, the product combined in this way as a whole has the same number of pages as one layer of a longitudinally folded newspaper product. Because of its half format, a tabloid section or magazine section has double the number of pages in comparison with a newspaper section of the same thickness and size.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the present invention is represented in the drawings in several working positions and will be described in greater detail in what follows.
Shown are in:
FIG. 1, a schematic side elevation view of a folding device superstructure with a device in accordance with the present invention in a first paper web guide;
FIG. 2, a schematic front view of the longitudinal formers in accordance with FIG. 1, showing the course of the longitudinal cuts of the paper webs upstream of the former inlet, as well as the representation of the longitudinally folded products, as well as their cross sections following a first as well as a second transverse cutting process without a paper guidance, draw-in and longitudinal cutting device;
FIG. 3, a schematic side elevation view of the folding device superstructure with the device in accordance with the present invention in a second paper web guide;
FIG. 4, the schematic front view of the longitudinal formers in accordance with FIG. 3, showing the course of the longitudinal cuts of the paper webs at the former inlet, as well as the representation of the longitudinally folded products as well as their cross sections following a first as well as a second transverse cutting process without a paper guidance, draw-in and longitudinal cutting device;
FIG. 5, a schematic side elevation view of the folding device superstructure with the device in accordance with the present invention in a third paper web guide;
FIG. 6, the schematic front view of the longitudinal formers in accordance with FIG. 5, showing the course of the longitudinal cuts of the paper webs at the former inlet, as well as the representation of the longitudinally folded products as well as their cross sect
