It is well-known that the rubber-coated roll occurs abnormal vibration, when operating roll speed of rotation becomes higher than the critical speed. We investigated the vibration of the rubber-coated roll from the view point of a standing wave generated on the rubber surface. The limit curve to occur the standing wave was derived by using approximation technique. Moreover, we solved the relationship between the occurrence conditions of the vibration and parameters of rubber coated roll. The standing wave is easier to occur, as tan δ becomes lower and rubber thickness relative to the diameter of roll core increases. The wave number of occurred standing wave becomes greatly lower with increasing the operating speed of the roll.
