Abstract (en)

A paper mill has a paper web winding assembly with a roller that takes up the paper web. The winding assembly has a natural frequency arising from its dynamic running characteristics and a frequency modification assembly (100). The frequency modification system switches the frequency between two or more values and is continually variable and acts by altering the roller bearing stiffness.
