High-Frequency Self-Excitation in Paper Calenders

Authors

  • E. Brommundt

Abstract

High-frequency self-oscillations can occur in paper calenders due to the compression of the paper in the nip together with the friction between paper and cylindrical rolls. Wear will follow and corrugate the rolls. This article elaborates a model demonstrating this effect and gaining insight into some details of the mechanism. The model parameters are chosen rather roughly so that the numerical values of the results will have little practical relevance. But the model uncovers parameters which, when changed, stabilize or destabilize the system. These tendencies might be compared with observations at machines to check the model.
