  1. 1. Combining X-ray and 3D scanning of logs

    Författare :Johan Skog; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing engineering and work sciences - Manufacturing engineering; Produktion och arbetsvetenskap - Produktionsteknik; Träteknik; Wood Technology;

    Sammanfattning : In Scandinavia, sawlogs are typically sorted upon arrival at the sawmill. Presorting of sawlogs according to dimension, e.g., using an optical three-dimensional (3D) scanner, is used to make the sawing process more efficient. LÄS MER

  2. 2. Planing wood with twist

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

    Sammanfattning : About half the total volume of sawlogs end up as sawn timber. The rest is lostdue to drying shrinkage or is turned into byproducts like wood chips, sawdustand shavings. As the raw material is a large expense for a sawmill, it is important to fully utilize the logs. LÄS MER

    Sammanfattning : Degradation of wood is a complex problem dependent on many parameters, but especially the presence of excessive amounts of water causes many problems.The objective of this work was to study the influence of various parameters on water absorption and desorption in Norway spruce (Picea abies (L.) Karst). LÄS MER

  5. 5. Total quality management in sawmills

    Författare :Carl-Gustav Lundahl; Luleå tekniska universitet; []

    Sammanfattning : This work was initiated in order to show the potential for Swedish sawmills to achieve higher productivity by implementation of improved process control tools in breakdown and production flows. An effective and profitable sawmill must utilize its raw material and the skill of its staff effectively. LÄS MER
