CA 2380801
The invention relates to a method in the process of manufacturing and/or finishing a fibre web (11), in which method said continuous and moving web (11), and/or a moving means (16, 17) related to the processing of the web (11), is monitored by one or more thermal cameras (10) of the infrared range or a corresponding detec- tor/detectors for the purpose of controlling the quality or condition. According to the invention, a substantially continuous two-dimensional thermal image or continu- ous thermal chart (20) of an object (11, 16, 17) being monitored and in a propagating and/or rotating move- ment is formed by said detector/detectors in a time- resolved manner and in synchronization with the move- ment of the object (11, 16, 17) in the direction of the movement. To determine the properties of the object (11, 16, 17) and/or to detect defects in the object from the continuous thermal chart (20), local deviations and/or discontinuities (21, 22) in the temperature, par- ticularly in the direction of movement, are detected, and the cause of said deviations and/or discontinuities (21, 22) is identified on the basis of the periodicity of said phenomena in the direction of movement.
