Hard-nip calender Hard-nip calenders are used for a variety of paper and board grades. In this calendering process, the web is pressed between two or more hard rolls. Hard-nip calenders of two main categories are used: Two-roll hard-nip calenders Multi-roll hard-nip calenders Two-roll calenders are primarily used for calendering webs that do not need heavy
