  • Process for reducing vibrations of successive sets of rolls and a roll arrangement having reduced vibratory tendencies
    Patent number: 5024150
    Abstract: To reduce vibrations occurring in sets of rolls that are immediately successive along the direction of travel of a web conducted through the nips formed between the roll sets, a process, especially for use in double calendars used to treat paper webs, is disclosed in which the natural frequency of one set of rolls is altered with respect to the natural frequency of the other set of rolls. In this manner, randomly occurring vibrations in the first set of rolls do not produce a resonance excitation of the second set of rolls. A roll apparatus having reduced vibratory tendencies also is disclosed.
