Abstract (en)

[origin: EP1357225A1] In a paper-making finishing process a paper web (27) is treated in a calender at high temperature and pressure and then wound onto a spool. Prior to leaving the calender the paper is esp. cooled, then moistened, then further cooled. Following emergence from the calender the paper is again cooled, before being treated (62, 64) on one side from steam and then moistened on the other by an elastic roller (25). A cooling unit (37) is located prior to the last nip (25) point.
