  2. 1. On Heat and Paper : From Hot Pressing to Impulse Technology

    Author : Marco Francesco Carlo Lucisano; KTH; []
    Keywords : Paper; Impulse Drying; Heat Transfer; Phase Change; Heat-Pipe Effect; Delamination; Flashing;

    Abstract : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. READ MORE

  5. 3. Static and Dynamic Modelling of the Drying Section of a Paper Machine

    Author : Magnus Karlsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pappers- och massateknik; Modelling; Wood; Paper; Multi-Cylinder; Simulation; Control; Steam; Air; Dew Point; Moisture Gradients; pulp and paper technology; Pressure Gradients;

    Abstract : The paper making process involves chopping of wood, cooking and forming, followed by dewatering in a vacuum section, press section and drying section. Several models for the most important parts of the paper machine drying section are presented in this thesis to describe phenomena at steady state and during state transitions. READ MORE

  7. 5. Mechanics of paper webs in printing press applications

    Author : Artem Kulachenko; Sören Östlund; Thomas Abrahamsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travelling webs; skew tension profiles; mixed dynamic formulation; fluting; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. READ MORE
