Abstract

The present invention relates to a device and a process for calendering web-like material on both sides. The device comprises a soft first roll 12, a second roll 14, which is arranged such that it is in nip contact with the first roll 12, the first and the second roll forming a first nip, and a soft third roll 13, which is arranged such that it is in nip contact with the second roll 14, the second and the third roll forming a second nip. According to the invention, the device further comprises members for turning and guiding a band 11 coming from the first nip such that that side of the band 11 which bears against the soft first roll 12 in the first nip is in the second nip facing towards the second roll 14. With the invention, it is possible to reduce the number of rolls in the calender, thereby cutting the production costs. <IMAGE>
