1. On Modelling and Estimation of Curl and Twist in Multi-Ply Paperboard
Sammanfattning : This thesis describes a grey-box model for the dimensionalstability properties (i.e. curl and twist) of the carton boardproduced at AssiDomän Frövi paper mill in Sweden.AssiDomän Frövi AB is one of Sweden major cartonboard manufacturer, and produces some 350000 ton of board peryear.

2. Beyond averages – some aspects of how to describe a heterogeneous material, mechanical pulp, on particle level
Sammanfattning : For a more profound understanding of how a process works, it is essential to have a relevant description of the material being processed. With this description, it will be easier to evaluate and control processes to produce more uniform products with the right properties. LÄS MER
3. Residual stresses in paperboard and the influence of drying conditions
Sammanfattning : The drying sequence in the manufacturing process for paperboard involves evaporation of water, primarily from within the fibres. The vapour is then transported out of the web by pressure or concentration gradients. LÄS MER
