Document Type and Number:
Japanese Patent JP2010529440
Kind Code:
A
Abstract:
A process to measure at least one qualitative measure of a moving fibrous web. The fibrous web being a web of paper or cardboard. The process including the steps of influencing, evaluating and determining. The influencing step includes the influencing of at least one microwave resonator by the fibrous web. The evaluating step including the evaluating of at least one resonance curve of the at least one microwave resonator. The determining step including the determining of at least one quality measure of the fibrous web dependent upon results of the evaluating step.
