Operating machines with rotating components at desired speed of rotation comprises comparing this with critical speed producing resonant vibration and operating at speed with gap between it and critical speed or which oscillates about it

摘要

The method for operating machines with rotating components (01), e.g. a roller of a rotary printer and a roll of paper (02), at a desired speed of rotation comprises comparing this with a critical speed for producing resonant vibration. The machine is then operated at a speed which has a gap between it and the critical speed or which oscillates about it.
