What the press says about LINCK

Focus on recovery

A more effective sawline developed in cooperation between Derome and Linck

Derome invests in long-term profitability

In cooperation with Derome, the German supplier of sawmill machinery LINCK developed a system which allows better profiling and sawing.

Six additional guide rollers and a control system which can even handle S-shaped multi-radius logs guide the logs on their way through the sawline. This new system allows the sawing of more sideboards and centre products, reduces the amount of chips and relieves the board edger."Previously the board edger represented a bottleneck for us", says production manager Per Andersson. "The fact that we can profile and saw with higher precision in combination with more sawblades at the primary saw unit, we can now increase our recovery by at least 5%."

The efficiency is also due to the fact that the data of the log scanner is sent to the existing control and to the new Linck control. Both systems analyse how the log can be processed best; the optimum sawing can be preferred in conjunction with the current prices."Sometimes the older system finds the better solution, but as a rule Linck is winning, ", says Per Andersson. Today Per Andersson can look back to a project that provides better results than expected.

"It went like clockwork", he notes with satisfaction. "We stopped production on Christmas 2012, started again in February and already received positive results for the sawmill Derome during the year 2013." Even Claes Otterbeck from LOAB, Linck representative in Sweden, is very satisfied with the Derome project. "The cooperation with Derome and Per Andersson worked very well. Their interest, knowledge and participation helped us to take curve sawing and optimisation a big step further to what we call spline optimisation. Without Derome’s help it would not have been possible to do this", says Claes Otterbeck. Presently, reovery of the Derome line has increased by 5% with this new active and more precise sawing method, while the production capacity also increased by eliminating the bottleneck at the board edger.

The increase in production is even higher than calculated. But as with everything; if a bottleneck is eliminated, a new one comes up. "Today we have no way to dry the higher amount of lumber produced", says Per Andersson. "Therefore we are now building a progressive and channel dryer as well as a new power plant to produce enough heat for the new dryer. "The new power plant burns bark which was previously not possible as the old mill had to be heated with sawdust to achieve sufficient heat for drying. From summer on, primarily bark is used for heating, if required with a small amount of sawdust. The surplus of sawdust is then sent to the Derome pellet factory in the nearby Kinnared. Both dryers as well as the power plant shall also be available until summer.

Also the lumber sorting plant shall be replaced during the three-week holidays."The new CG lumber sorting plant will have a much higher capacity, the Finscan camera based quality scanning system will allow a better quality scanning", states Per Andersson. Even right in the middle of a difficult economic situation, Derome did not shy away from investing in higher performance and more effective sawing. As a family business, you do not need short-term financing but you can invest in the long run. "It costs less if you are at a standstill in an economical crisis", says Per Andersson. "Sometimes it is even cheaper to build. But above all, we have to increase further capacity.

We see an increasing interest from the political side to build with wood and the raw material wood has now also found another growing application. Therefore we want to increase both in the long run, capacity and raw material utilisation."Derome can report from personal experience that the building of timber housers increases as they are also a major house manufacturer. In Varberg e.g. Derome is building approx. 1500 apartments, single- and multi-family houses with several floors, on their own grounds. They also produce pre-assembled construction sets (prefabricated parts) for other construction companies and private persons as well as several prefabricated parts for houses with up to six floors. 20 % of the Derome lumber production is used for the own production of timber houses. The Derome group also maintains a building trade completely oriented towards professional customers as well as an own production of roof structures and other building elements.

The considerably increased interest in timber houses still exists for some time as a whole year of future architects visited Derome for study purposes. "This did not happen before", states Per Andersson. "Sometimes we had some students of architecture with special interests here but not a whole year. This shows clearly that the attitude towards the timber house construction has changed." From the 80% of production which Derome does not sell to the own house manufacturing, the majority is exported. A large part is transported to Great Britain via the harbour in Varberg. Derome has operated an own impregnating plant there for eight years, Woodtech, where they also impregnate lumber from other manufacturers. Lumber is also sold and delivered by truck to Denmark and Germany.
