  • Patent number: 5439366
    Abstract: A safety device for the roll space within a calender or other roll machine is disclosed. The rolls when rotating, excite oscillations in the beam at the resonant frequency of the beam. This can occur during start-up or during normal operation. The safety device of the present invention comprises a beam and additional mass that is oscillatorily suspended from the beam in order to reduce the amplitude of the beam oscillations at the beam resonant frequency. In addition, a damping element between additional mass and the beam is used to reduce any undesired oscillations due to newly created resonant frequencies introduced into the system.
