Abstract (en)
[origin: WO2012163614A1] The invention relates to a printing machine having at least one printer unit comprising at least one inkjet printhead, a central printing cylinder, and a drive motor of its own dedicated to the central printing cylinder. A conveying path of a printing material web through the printing machine has at least one first section and one second section, each defined by contact points of the printing material, which have motor-powered rotation bodies. At least the first section has a dedicated first measuring device for measuring a web tension of the printing material web in the first section. At least the second section has a dedicated second measuring device for measuring the web tension of the printing material web in the second section. A machine controller is arranged, by means of which the web tension in at least the first section and/or in the second section of the conveying path of the printing material web can be adjusted and/or is adjusted, taking into consideration at least both a measuring result from the first measuring device and a measuring result from the second measuring device. The invention further relates to a method for adjusting a web tension of a printing material web.
