one of the OLI cylinders had an offset of 0.400’’. Therefore, the cant positioning was not accurate, and this had a direct impact on the production value for one month. The mechanical alignment problem was identified once the Primary Breakdown SmartTool was installed. After fixing the error, the cant positioning resumed to an acceptable 0.010’’ automatic infeed offset. In another incident, during production an OLI saw guide was damaged by a log. This caused the bandsaw to cut the wood two hundred thousandths off the
dimension target, so it had a direct impact on the production quality. The problem was identified by the Primary Breakdown SmartTool and displayed in the dashboard, but it was not noticed by the operator. Fortunately, an alarm was triggered automatically, and the operator became aware of the situation. In another sawline event, during the canter cutting tool cylinder calibration, the minimum cylinder position setting was defined at 2 in’ in the PLC and 1.9 in’ in the optimizer. This error caused the 4 in cants to be cut one hundred thousandth bigger. Since this
pattern was not common, the problem was difficult to spot and lasted several months. It was only identified when the Primary Breakdown SmartTool was installed. The client was skeptical at first, but after investigation he recognized the facts and corrected the setting.

Setra makes major investment in Bergslagen
S
etra is expanding drying capacity at Heby and Hasselfors – a decision taken by the Board of the wood products company at its latest meeting. “The investment is part of the development strategy for Setra in Bergslagen,” explains Setra’s CEO Katarina Levin. The investment in both highcapacity drying kilns totals SEK 100 million. “The new drying kilns will enable us to improve value optimisation and boost efficiency, which will strengthen Setra’s competitiveness,” says Jonas Fintling, Mill Manager Setra Hasselfors. Setra Heby’s Mill Manager Jan-Erik Vik agrees, adding that the investment will also improve the work environment in Heby, as it will mean replacing some of the older equipment. The increase in drying capacity at the sawmills in Heby and
Hasselfors is an important element in the ongoing development of Setra’s operations in Bergslagen. Earlier this year, the decision was taken to invest in a new saw line in Skinnskatteberg, and last year a new rip saw was installed at the sawmill in Nyby. “Setra is investing heavily in greater refinement of wood at resource-efficient production units in the Bergslagen area. This is positive from a sustainability perspective, as it helps to lower the climate footprint of our production and to ensure that we manufacture greener and more climate-smart products,” says Katarina Levin. Examples of investments include CLT and components at Setra’s new factory in Långshyttan, planed construction timber from the new trimming and planing plant in Hasselfors and new x-ray technology in Kastet, Nyby and Skinnskatteberg. In total, Setra has invested more than SEK 1 billion
Katarina Levin Setra’s CEO in Bergslagen over the past four years. Another example of green investment is the company Pyrocell, which Setra owns jointly with Preem. Pyrocell manufactures bio-oil from sawdust. The bio-oil is then used as a renewable raw material at Preem’s refinery in Lysekil, where it is mixed with petrol and diesel. Pyrocell’s facility is integrated with Setra Kastet in Gävle. Together, Setra and Preem have invested over SEK 400 million in this exciting venture.
