driven roll and a filled roll. The expression for the creep ratio was found to agree well with their experimental results with an eight roll supercalender. Elasticity theory of an elastomeric roll driven by an iron roll allows the calculation of the creep ratio using Young's elastic modulus along with the Poisson's ratio of the rolls.
