3.9.4 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.
