ABSTRACT:
An apparatus for conveying a tape material having different surface moduli on either side by nipping with a pair of rotatable rollers and a method of conveying the same is disclosed. The tape material having different surface moduli is conveyed by an apparatus having a pair of rollers having different surface moduli with each other, so that the roller in contact with the relatively higher elastic modulus side of said tape has a relatively higher surface elastic modulus, and the roller in contact with the relatively lower elastic modulus side of the tape has a relatively lower surface elastic modulus.
