THE MECHANICS OF TENSION CONTROL
2019 2 18 Remember the equation of torque = tension x radius is linear so torque must be decreased for unwinds and increased for rewinds at a linear rate relative to roll radius For example if you start with a 17.5 inch roll radius 35 inch diameter and unwind down to a 1.75 inch core radius 3.5 inch diameter 17.5 divided by 1.75 is 10 1 ratio.
