The disclosure of this invention relates to a method and apparatus for processing strip-like material, such as paper and synthetics. It includes a multi-roll calender in which the material is passed around the rolls in a serpentine manner so that the rolls have material-contacting portions and nonmaterial-contacting portions. External induction heating is applied to the material-contacting portions of the rolls to heat the rolls immediately under the material. The temperature of the rolls are measured by sensors at the noncontacting portions of the rolls.
