“Doing this during a pandemic has been rather challenging, because we have had to work remotely with the supplier on some of the calibrations, but otherwise everything has gone to plan,” explains Johan Fredriksson, head of production technology at Sävar Sawmill.
Passed with flying colours
At the start of the year, Norra Timber began performance-testing the newly installed edger, which uses a Catech system with a capacity of 57 boards per minute. The results have been extremely positive, with the edger operating reliably and at high capacity. The edger was supplied by USNR and is fitted with the latest technology, BioLuma 2900L sensors, which scan each board at high resolution and use that visual information to determine which product will be edged in the machine. The investment in the edger is an important factor in achieving the target of increasing production by 6% per year.
“We are now more robust, because the two older edgers were a bit of a bottleneck. We previously had to choose between slowing things down or running longer logs, but with our latest investment we can optimise the choice of edgers and continue to maintain a steady pace at all times,” says Tom Löfgren, production engineer at Norra Timber.
Installing the machine also involved erecting a new building of around 1000 m², with concrete being replaced with wood as the building material wherever possible. The floor structure, for example, is made from panels of cross-laminated timber and the frame is glulam. In addition to the edger, the new space also houses electrical maintenance. The total investment of SEK 35 million has included two new press binding machines on the trimming line, which are used to press together and tie bands around the packs of wood.
“With the new building, the new edger and the new press banding machines in place on the trimming line, our modern facility has taken yet another step forward, allowing us to further increase capacity,” says Fredrik Samuelsson, sawmill manager at Sävar.
