At every sawmill, the dream has always been to be able to see inside the log before it is sawn. Why? Because saw logs are a biological raw material whose properties vary a great deal. To make best use of the raw material, it is therefore a huge advantage to know the log’s properties before you decide how it will be sawn - and that is where CT Log comes in.
Norra’s installation of a Microtec CT Log scanner at Sävar Sawmill is the first of its kind in Scandinavia and the first ever to be fully integrated into the saw line to directly control the breakdown process. This investment of around SEK 30 million is being made in conjunction with the previously announced refit of the saw line itself. These two investment projects will give Sävar Sawmill the most modern saw line in the world.
"My warmest congratulations to Norra for choosing groundbreaking CT technology to accompany them into the future of sawmilling. We are very happy that Sweden, being such an important country in matters of wood processing, acts as a pioneer introducing this new technology. We are looking forward to cooperating with Norra, our local partner LOAB and international partners which are taking part in this project", states Federico Giudiceandrea, Microtec CEO.
“Since both our sawmill managers, Stig Grundberg and Johan Oja, have been leading figures in the development of this technology, we now have an opportunity to take a leap forward that will leave our competitors playing catch-up for some time to come,” states Lärkeryd.
Norra's CT Log will be the sixth CT Log running worldwide. There are five CT Logs already in operation: two in Europe and three in America.
CT Log scanner chooses the cutting pattern that maximises overall resale value of ALL boards cut out from a log, minimizing waste.
CT Log is the only scanner capable of giving a complete 3D reconstruction of all inner features of a log.
The precise scanning is combined with the latest bandsaw technology from Söderhamn Eriksson / USNR - where the focus is on thin kerfs and high speed - ensuring maximum yield. “We want to recover as much as possible of every log. We set a target of doubling the speed and halving the cut surfaces,” says sawmill manager Stig Grundberg.
Norra Group is an expanding forest company owned by 17,000 private forest owners with combined forest holdings of over a million hectares in northern Sweden.
Norra Group has a turnover in excess of SEK 2 billion and directly employs around 350 people.
