摘要： The invention relates to a method in the control of the quality or the condition of a fibre web (21) on the basis of optical imaging diagnostics, wherein the fibre web (21) under examination and/or means (22, 23) relating to the processing of the fibre web are monitored with at least one optical imaging measuring device (1 to N). According to the method, the scale of the observation area of said at least one imaging measuring device (1 to N) is calibrated, when said measuring device is taken into use, by means of one or more calibration objects placed in the observation area of the measuring device, to correct the perspective error caused by the position between said measuring device and the object (21, 22, 23) observed by it.

摘要： The invention relates to a method for synchronizing information produced by imaging optical measuring devices (1-N) which monitor the manufacturing and/or finishing process of a fibre web, in relation to the movement of the fibre web in the machine direction, which method comprises the steps of monitoring the moving fibre web and/or a moving means involved in its processing in the machine direction by means of imaging measuring devices (1-N) placed in successive measuring positions in the machine direction, and searching the information recorded by imaging at different measuring positions, for images, or the like, relating to the same local area of the fibre web, for their analysis and/or storage. In the method according to the invention, the images, or the like, recorded in the different measuring positions, are searched, by digital pattern recognition, for a feature/features (30) relating to the same local area of the fibre web, and the travel time delays of the fibre web between the different measuring positions are determined on the basis of time data included in said feature/features (30) upon the recording of images, or the like, in the different measuring positions. The invention makes it possible to automatically synchronize information measured by imaging in a significantly more accurate and adaptive way than in prior art.

摘要： A method in the process of manufacturing and/or finishing a fiber web (11), in which method the Continuous and moving web (11), and/or a moving device (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 detector/detectors for the purpose of controlling the quality or condition. A substantially continuous two-dimensional thermal image or continuous thermal chart (20) of an object (11, 16, 17) 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 (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, particularly 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.

摘要： A method and apparatus for automatically marking paper, board or cellulose web rolls at a slitter for the purpose of identifying the rolls during later finishing steps. Such finishing operations include, e.g., roll transport, rewinding, sheeting or other finishing steps and roll packaging. The roll identification code is also used for material management related to customer rolls. The roll identification information of a roll set leaving the slitter, that is, the sequence of rolls exiting from the slitter as a group is transmitted for the use of the roll marking equipment and the customer rolls are moved away from the slitter area only via the roll marking equipment and new rolls are prevented from entering the slitter area in any other form except as a new roll set. As a result, the correct identification data for each roll set is continuously available to the marking equipment.
