Woodland, Washington– Norra Timber, owned through an economic association with a large number of private forest owners in northern Sweden, recently invested in a third edger to handle the large number of side boards from the saw line. Among other things, this drive has led to the commissioning of the world’s fastest band saw line in 2017. The line was supplied by USNR, headquartered here, and is capable of sawing speeds at 155 meters per minute (508 ft/min). Now they have invested in a third edger to handle the large number of side boards from the saw line.
At the start of the year, Norra Timber began performance-testing the newly installed edger, which is 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 system was supplied by USNR and is fitted with the latest scanning technology. USNR’s BioLuma 2900L sensors scan each board at high resolution and use that highly dense data to determine which products will be edged in the machine.
“The investment in the edger is an important factor in achieving the target of increasing production by six percent per year. We are now more efficient because the two older edgers were a bottleneck. We previously had to choose between slowing things down or running with wider log gaps. With our latest investment we can optimize the choice of edgers, and continue to maintain a steady pace at all times,” says Tom Löfgren, production engineer at Norra Timber.
