Abstract [en]
The Swedish research institute Innventia has taken a look into what the future needs will be for online measurements techniques in paper production. Discussions in a group consisting of experts from industry and academy, of paper and board production, measurement techniques, analysis methods and quality control systems resulted in a roadmap describing tomorrow’s needs of new applications of measurement techniques. The starting point was a vision of a high-resolution, multispectral online analysis of the complete produced area combined with new approaches for interpretation of measurements, to give better and more complete information of the paper production. One approach is to combine modern infrared (IR) imaging systems with data from the existing quality control systems in order to obtain the local grammage variation, to achieve more detailed information for optimisation of the process. The IR camera technique has been studied at the institute for 7 years, both in laboratory studies and at mills. Another online measurement technique that has been developed and studied is the online optical topography system OptiTopo. This gives information of the surface structure variation both in fine-scale and in large-scale. This instrument also gives valuable input in the quality control system. Examples from the two systems are shown.
