Optimizing Tension Control In Central Drive Winders
Both the position controller for dancer based systems and the tension controller for load cell based systems can be commonly referred to as technology controllers (see Figure 3). A technology controller is a closed loop control system that applies correction
Web Tension Basics Webconvertltd
Closed Loop Control System with Dancer Roll The Dancer Control does the same job as the above example, but with a different feedback. In this case, the feedback to the controller comes from the position of the dancer. If the dancer in the picture is too high, then tension is too high, and the controller knows that it must reduce the brake pressure.
