  • Patent number: 6615709
    Abstract: The invention concerns a method for detecting a contamination and damaging of a face (10) that runs through a nip or nips (N1 . . . N10) in a calendar for paper. In the method vibrations occurring in connection with the constructions (18, 100) of a calendar are detected and processed. The vibrations are detected by at least one vibration detector (40; 41 . . . 46; 41a. . . 46a, 41b. . . 46b) fitted in connection with the bearing supports of calendar rolls (11 . . . 16) or in connection with constructions (18, 100) related to said bearing supports. By the way of these vibration detectors the calendar roll(s) (11 . . . 16) is/are identified from which the vibration derives.
