Abstract: In some process contexts it is desirable to maintain a constant strain on the web instead of constant tension. The novel system measures the caliper of the web material and adjusts the tension to achieve the desired constant strain. The caliper may be measured by monitoring the radius of the expiring web reel in connection with the angular position of the reel. The web caliper is input into a control scheme that includes an algorithm determining the appropriate tension to applied to the web in accordance with its caliper. The control scheme outputs a variable force command to a dynamic dancer which adjusts the web tension and thus sets the constant web strain. The variable force may be injected via an air cylinder, a hydraulic cylinder, a spring with a dynamic ground, or an electromagnetically driven actuator.

Abstract: A continuous filter tow is advanced through a combined wrapping and condensing station by an endless belt, and the thickness of the belt decreases as a result of wear. The resistance which the condensed tow offers to the flow of air is measured by a pneumatic detector at the aforementioned station, and the accuracy of such measurement is affected by decreasing thickness of the belt as a result of increasing rate of escape of testing fluid along the belt. Therefore, the thickness of the belt is monitored and signals which are generated to denote the thickness of the belt are used to correct signals which are generated to denote the resistance to the flow of air. The correction involves modifying the signals denoting the resistance to the flow of air to denote a more pronounced resistance proportionally with decreasing thickness of the belt.
