Abstract
A method in the process of manufacturing and/or finishing a fiber web (), in which method the Continuous and moving web (), and/or a moving device () related to the processing of the web (), is monitored by one or more thermal cameras () of the infrared range or a corresponding detector/detectors for the purpose of controlling the quality or condition. A substantially continuous two-dimensional thermal image or continuous thermal chart () of an object () being monitored and in a propagating and/or rotating movement is formed by said detector/detectors in a time-resolved manner and in synchronization with the movement of the object () in the direction of the movement. To determine the properties of the object () and/or to detect defects in the object from the continuous thermal chart (), local deviations and/or discontinuities () in the temperature, particularly in the direction of movement are detected, and the cause of said deviations and/or discontinuities () is identified on the basis of the periodicity of said phenomena in the direction of movement.
