What Is Web Tension Control Systems Concepts
Jun 13, 2019 Tension Calculation. Mathematically, tension equals torque divided by radius. This means that as a roll diameter increases or decreases, torque must be adjusted to maintain tension at the optimal value, or setpoint. So in a basic sense, by controlling the torque in a uniform manner in relation to the roll, we control tension.
