ABSTRACT:
A calendering apparatus in which a nip portion is formed by a chilled roll, a backing roll and an endless elastic belt arranged over the backing roll, wherein a paper sheet to be treated passes between the chilled roll and the endless elastic belt. Thus, a paper sheet having a remarkably improved smoothness and gloss can be obtained by the calendering apparatus of the present invention using an endless elastic belt having a relatively long length, without the disadvantage of a heat build-up occurring in a usual calendering treatment. A contacting angle between the belt and the backing roll is 30.degree. or less.
