Abstract

A paper-analysing process for localizing faults in the machine elements of a papermaking machine, in which at least one quality variable of the paper is detected from the paper web as a function of the length variable of the web and a quality-variable-characterizing quality signal is formed, which is mathematically analysed in order to determine faults in the quality variable which regularly recur and have a certain frequency.
