6.5.6 Draw control
Draw control is a sort of Open Loop tension control. Draw is the ratio of speed difference between one roll and the
other. Tension is generated as in the following equation.
V2
V2 - V1
D 
Where,
V1, V2: Transfer speed of each roll (m/min)
T: Tension (kg)
E: Elasticity coefficient of processed material (kg/mm2)
S: Sectional area of processed material (mm2)
