Improving the Accuracy of Winding Arm Motion and Nip Load Control on a PaperCenter Winder

摘要

The quality of the roll and the amount of breakages produced in paper finishingare influenced by the properties of the paper and the accuracy of roll transfer movement and nip load control. The paper describes the development of a new control method for center winders, by means of which it is possible to reduce roll damage and to carry out the roll transfer movements more rapidly and accurately than with the methods presented previously. As the result of the work, the theory and experimental measurement results for a control method developed for the center winder, as well as for the sub-methods involved in this control are presented.
