Problems solved by technology

The problem with all printing presses with a width of 2 pages or more is that the web width varies, that is to say different widths of webs are used in the printing job and in the prior art it is necessary to make the rotary web press with the The corresponding tape width used is more or less complicated to adapt
[0012] Previous web printing presses were therefore either too inflexible (in particular, depending on the configuration, 2-page jumps were not possible or not always possible) or too complex (mainly regarding adaptation to variable web widths) or only with many printing towers to fulfill

Embodiment Construction

[0055] figure 1 with 2 as well as Figure 4 with 5 The rotary web printing presses are shown, respectively, with web changing devices 1a, 1b, 1c, 1d, printing towers 2a, 2b, 2c, 2d, and a belt turning device 3a including a plurality of printing devices 6a, 6b, 6c, 6d , 3b, 3c, 3d, and folding machine 8, wherein the belt turning device 3a, 3b, 3c, 3d can make the sub-belts 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d, 37a from the printing tower 2a, 2b, 2c, 2d turn 90° toward the folding machine 8. The belt turning devices 3a, 3b, 3c, 3d are arranged above the printing towers 2a, 2b, 2c, 2d in a direction P perpendicular to the installation plane E. The folding machine 8 is designed as a single-width folding machine, as Figure 13 As shown, that is to say, it can process a paper tape 7a or sub-tape 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d, 37a with a width of two pages P1, P2, and the paper tape or sub-tape can It is guided through the folding device 13 and folds in the center accordin...

Abstract

The invention discloses a rotating roller print assembly, comprising roller exchanging devices (1a,1b,1c,1d), a plurality of printing drums (2a,2b,2c,2d) with a plurality of printing devices (6a,6b,6c,6d), web turning devices (3a,3b,3c,3d) and at least one folding apparatus (8), wherein the web turning devices (3a,3b,3c,3d) turn paper webs (7a,7b,7c,7d) or partial paper webs (17a-17d, 27a-27d) around 90 degrees from the printing drums (2a,2b,2c,2d) to the folding apparatus. Preferably, the folding apparatus (8) is designed in the fixed width.

Description

Technical field [0001] The invention relates to a rotary web printing machine, which has a web changing device, a printing tower including a plurality of printing devices, a belt turning device (Bahnwende) and at least one folding machine. Background technique [0002] The following prior art has been disclosed: [0003] DE 102 36 864 B4, EP 0 741 020 A2, WO2007 / 068643A1, EP 1 477 311 A1 and DE 20 2009 007 737 each introduce a rotary web printing machine, which has a roll changing device and includes multiple printing devices The printing tower, the belt turning device and at least one folding machine, wherein the paper belt is turned 90° towards the folding machine after the printing device. In this regard, at least some of the printing tower or the reel changing device and the printing tower are installed aligned in the first direction (input direction), in which direction the paper tape is guided by the reel changing device to the respective printing tower, and the paper The b...
