Abstract (en)
[origin: EP0341457A2] The calender arrangement (100) comprises two pairs of rollers (10, 20) which the paper web (1) runs through successively. The pairs of rollers (10, 20) each comprise a highly heated hard roller (2) and a soft roller (3). The nips (9, 19) thus formed are each preceded by a cooling device (5, 13) in order to limit too high a heating of the interior of the paper web (1) and the partial internal plasticisation associated with this.
