Introduction | Application examples
Tighten the web via trimming function with cascade
In case a clearance has developed, the web must be "tightened" again. Only then the
machine can be accelerated again via the master. The subsequent slave (cascade structure)
must run along in the set ratio. Thus, the trimming function acts directly before or after the
stretching factor.
