Description

The invention relates to a method and a printing machine for producing printed products according to claims 1 and 5, respectively.

In the DE 10 2011 076 899 A1 a web-fed printing machine operating according to the inkjet method is disclosed.

Also the EP 2 305 466 B1 discloses a web-fed printing press operating according to the ink jet, with a further processing unit being arranged downstream of the printing unit. The further processing includes, for example, a longitudinal cutting device, by which a web is divided into two partial webs and then two fold formers can be fed.

Through the WO 2013/164161 A1 a method and a device for the production of book blocks are known, wherein a not yet folded web is first cut into web sections with a width of several pages, these are subsequently collected in stacks on top of one another, and these are finally cut into individual book blocks.

The WO 2005/108262 A1 discloses an offset printing machine format-variable cross folder in the web path downstream of a former.

The DE 100 60 758 A1 relates to a cutting device in a folder of a web-fed rotary printing press, which is designed to cut signatures with variable section lengths.

Through the EP 2 103 428 A2 a folder with two collecting cylinders following one another in the product flow is known.

The DE 103 25 362 A1 relates to a method and a device for indirect digital printing of images on webs. After printing, the printed web can be wound up or, alternatively, processed further using a cross cutter.

Through the DE 10 2012 103 729 A1 A method and a device for producing printed products are disclosed, a printing machine for variable format printing, in particular a digital printing machine, further processing being provided with a cross-cutting device, a collecting device, a cross-folding device comprising a jaw cylinder and a collator for stacking sections. In a broadsheet production it is possible to use a web in the width of two or more page heights, such a web being cut lengthways in a longitudinal folding device and the partial webs being placed on top of one another before they are cross-cut into signatures.

The invention is based on the object of creating a method and a printing machine for producing printed products.

The object is achieved according to the invention by the features of claims 1 and 5, respectively.

The advantages that can be achieved with the invention consist in particular in the fact that a multi-page printed product, in particular a tabloid product, of variable dimensions, can be created in a particularly simple and secure manner.

In particular, a folding device comprising a folding jaw cylinder enables smooth and thus low-interference and / or particularly high-frequency processing. The processing speed can also be increased in particular by the fact that several products can be processed next to one another at the same time. Furthermore, the processing of multi-page-wide sections, which is still retained for a large part of the route, also has advantages with regard to the susceptibility to twisting.

Embodiments of the invention are shown in the drawings and are described in more detail below.
