Abstract
In a hot strip rolling mill a velocity damping compensator circuit is added to the current regulating loop of the looper motor drive generating a torque on the looper arm mechanism between roll stands, thereby to prevent disturbances when applying the looper arm and looper roller against the strip being rolled.
