To control the cutting register of a web in a web-fed rotary press and to
control the tension in a web section, in a manner decoupled from each
another, at least one partial cutting register error is controlled at
least one web tension is controlled. The press has controlled driven
clamping points 0 to n, wherein j+q manipulated variables are used to
influence j partial cutting register errors and q web tensions.
Circumferential speeds and/or angular positions of clamping points are
used as manipulated variables and the partial register error and the web
tension in each case are located in the same or in different web
sections.
