The Roll Dynamics for High Speed Paper Manufacturing

The transverse, dynamic deflection of high speed, wide faced, composite tubular rolls is investigated. General procedures are proposed enabling the analysis of inter-connected units comprising both distributed parameter and rigid, point- wise models. Modelling methods, eliminating intermediate variables are employed facilitating the realization of an overall system, input - output representation. An illustrative study, detailing the analysis and evaluation process is presented. A high speed, MG paper making machine, table roll application is considered. Whirling conditions and the effect of this problem on sheet quality and manufacturing output is commented upon.
