Abstract:
A method of predicting a paper winding characteristic variable in a paper winding device, comprising the steps of:a) unwinding paper from a first paper reel and winding said paper onto a second paper reel; b) determining, in a preparatory step, depending on a measurable time-dependent characteristic variable of said step of winding at a known first influencing force, a first paper winding characteristic variable of said first paper reel and a second paper winding characteristic variable of said second paper reel, said first paper winding characteristic variable and said second paper winding characteristic variable being results of said preparatory step; c) setting a predictor that predicts a future second paper winding characteristic variable, utilizing said results of said preparatory step which are a function of said first and said second paper winding characteristic variable, and a time variable.
