PROBLEM TO BE SOLVED: To provide a bearing of a backup roll with a proper load even in the case of low linear load of a calendering nip. SOLUTION: In a calendering in which a long material passing through a nip N1 formed between a hot roll 12 and a backup roll 14 is calendered, the hot roll 12 has a recessed negative crown 23. Consequently, since a gap 27 is produced in the nip N1, in order to provide a fixed nip linear load, a press shoe 24 presses the shell 25 of the backup roll 14 toward the nip N1 more excessively than a common case. The bearings 32 and 34 are provided the reaction as a load.
