Abstract: The invention relates to methods for web tension adjustment in a processing machine for processing a web of goods, in particular in a shaftless printing press, in which downstream web tension segments are decoupled from an adjustment of the web tension in a first web tension segment defined upstream by a first clamping point and downstream by a second clamping point. To that end, the first clamping point is subjected to a first control instruction, which is generated using a first dynamic element with a non-constant transmission function, and the second clamping point is acted upon by a second control instruction, which is generated using a second dynamic element with a non-constant transmission function. As a result of the provisions of the invention, for decoupling the downstream web tension segments from the web tension adjustment and so forth, it is unnecessary to pilot-control the corresponding downstream clamping points.
