From the automatic tuning technology of DM4 system, a major conclusion is that self-tuning database technology should be based on the paradigm of a feedbackcontrol loop.
At each unwinder the film wraps around a load-cell-mounted roller, which monitors the film tension, providing the feedback signal for electronic automatic closed-loop tension control.
