The tension control can be based on the following principles DC motor Magnetic Powder Brake Pneumatic brakes Salient Features All the parmeters are user programmable Digital setting of tension with reesolution better than 0.1% High     Type of Feedback Speed/RPM feedback from non contact type sensors. Tension Feedback from Load Cell    Advantage: avoid loose wound or telescope-wound rolls. Hence, obtain tight and transportable rolls
