3.5 Tension Feedback
The Tension Control Function Module may be configured to use actual force tension
feedback to perform closed loop tension regulation. A force measurement device (typically
referred to as a Load Cell) is used to measure the actual force applied to the web. The load
cell does not apply a force to the web, as in the case of the dancer. The controlling section
applies the force to the web by pulling harder or by holding back. The load cell simply
measures the force on the web and provides the information to the controlling section.
