A modern paper machine is equipped with various finishing units e.g. calendars and coating units to produce better optical and printing properties. Today’s trend is to supply these finishing units with polymer covered rolls. Tampere University of Technology (TUT) has built up an experimental set-up to study both vibration phenomena and polymer behavior. One of the essential task is to determine and verify the soil-machine interaction. This paper presents the preliminary analysis of the vibratory behavior and experimental results of modal analyses.
