Method for determining dry content of running fibrous web transported on clothing upper surface by fibrous web manufacturing machine, involves measuring total water content by microwave sensor and calculating dry content of fibrous web

摘要

The method involves measuring the total water content by a microwave sensor (5) and calculating the dry content of the fibrous web by an evaluating unit (8). Particular clothing data is considered while determining the dry content of the fibrous web. The clothing data is the cloth-specific information, such as cloth material or weaving pattern. The clothing data is read from a data storage unit, particularly Radio frequency identificationtag (9) by the sensor and is measured by a running machine.
