Paper Machine Speed Increase

Paper machine speed increases can affect the vibration of the machine leading to problems in paper quality or in excessive vibration, shortening the life of the machine. This presentation shows the effect that a speed increase can have on paper quality and on the machine. It also covers the techniques used for predicting what the vibration will be when the machine speed is increased. Of particular concern is preventing unwanted resonances, to ensure that there will be no surprises at the higher operating speeds.
