Abstract
A method is disclosed for web tension setting in a processing machine for processing a material web, in particular a shaftless printing press. In order to set the web tension in a first web tension section with a length L which is delimited upstream by a first clamping point and downstream by a second clamping point, the first clamping point is loaded with a first manipulated variable which is produced using a first element with a first transfer function G(s) (G3), and the second clamping point is loaded with a second manipulated variable which is produced using a second element with a second transfer function G(s) (G4), wherein cG(s)=−cG(s). Thus, it is possible to keep the speed constant even during the regulation at a fixed or variable point x within the web tension section, wherein x=|c/(c+c)|L lies behind the first clamping point.
