Patent ID: 7149650

Claim:
A system for computer assisted monitoring of a cross profile of a quality parameter of a fiber material web during at least one of a production and a conversion of the fiber material web, said system comprising: a measuring system for measuring the cross profile and producing a measured cross profile; at least one computer based operations and logic unit connected to said measuring system, said at least one computer based operations and logic unit for a determination of a plurality of standard deviations of a plurality of interference profiles that are representative for a plurality of different interferences in a form of a plurality of different peak groups in said measured cross profile, said plurality of different peak groups differentiate in that respective peaks have different width ranges; at least one element connected to said at least one computer based operations and logic unit, said at least one element for at least one of a storage of said plurality of standard deviations, a display of said plurality of standard deviations and a further processing of said plurality of standard deviations.
