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 and 2 as well as Figure 4 and 5Respectively shows a rotary web printing machine with a web changer 1a, 1b, 1c, 1d, a printing tower 2a, 2b, 2c, 2d with a plurality of printing units 6a, 6b, 6c, 6d, a belt diverter 3a , 3b, 3c, 3d and folding machine 8, wherein, belt steering device 3a, 3b, 3c, 3d can make sub-band 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d, 37a from printing tower 2a, 2b, 2c, 2d are turned by 90° towards the folder 8 . The belt deflectors 3a, 3b, 3c, 3d are arranged in a direction P perpendicular to the mounting plane E above the printing towers 2a, 2b, 2c, 2d. Folder 8 is designed as a single-width folder, as Figure 13 As shown, that is to say, it can process the paper strip 7a or sub-band 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d, 37a with the width of two pages P1, P2, which can be is guided through the folding device 13 and folded in the center accordingly.

[0056] According to the band turning device 3a, 3b, 3c, 3d of above-mentioned ex...

Abstract

A rotary web printing machine is presented with a web changing device (1a, 1b, 1c, 1d), a printing tower (2a, 2b, 2c, 2c, 2d), a belt turning device (3a, 3b, 3c, 3d) and at least one folder (8), wherein the belt turning device (3a, 3b, 3c, 3d) can make the paper strip (7a, 7b, 7c, 7d) or partial belts (17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d, 37a) are diverted by 90° from the printing towers (2a, 2b, 2c, 2d) towards the folder (8). The folding machine (8) is preferably of single-width design.

Description

technical field [0001] The invention relates to a rotary web printing press with a web changer, a printing tower comprising a plurality of printing units, a belt deflector and at least one folder. Background technique [0002] The following prior art has been published: [0003] DE 102 36 864 B4, EP 0 741 020 A2, WO 2007 / 068643 A1, EP 1 477 311 A1 and DE 20 2009 007 737 each describe a rotary web printing machine with a web changing device, comprising a plurality of printing units A printing tower, a belt deflector and at least one folder, wherein the web is deflected by 90° after the printing unit towards the folder. In this aspect, at least some of the printing towers or the reel changing device and the printing towers are mounted aligned in a first direction (infeed direction), in which direction the web is guided by the reel changing device to the respective printing tower, the paper The webs leave in this first direction each from the printing tower or printing unit a...
