  1. 1. How planing affects warp

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Spiral Grain in Norway Spruce

    Författare :Harald Säll; Thomas Thörnqvist; Rolf Birkeland; Växjö universitet; []
    Nyckelord :Spiral grain angle; drying deformation; warp; wood quality; Norway spruce; Picea abies; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Sammanfattning : Wood is a major construction material that is used in many contexts, and for different purposes. Serious problems may arise, however, when moisture related deformations as twist occur in wood used in different types of building structures, joinery and furniture. LÄS MER
