  2. 1. How planing affects warp

    Author : Ann Axelsson; Stig Grundberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Although planers and wood machining researchers have been around a long time, the interactions between planks and planers have been neglected in basic research. With a solid understanding of the movements of planks during planing, planers and planing strategies can be developed to reduce waste and improve the value yield. READ MORE

  4. 2. Moisture-induced Distortion in Norway Spruce Timber - Experiments and Models

    Author : MARIE JOHANSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spiral grain angle; bow; spring; twist; wood; longitudinal shrinkage; crook; warp; compression wood; lumber;

    Abstract : Timber is a natural material that is environmentally friendly, renewable, light, strong and, in the eyes of most people, beautiful. Timber does, however, have one important drawback when it is used in a modern mechanised building process - its lack of straightness. READ MORE
