Pilot CLT production facility for Södra in Väröbacka
Company Södra Wood invested into a pilot plant for CLT production. The idea behind the pilot plant is to explore the different possibilities of the product and create a marketing and production strategy. As Södra operates their own saw mills the utilisation of different timber sizes and grades is also crucial.
The line has been placed in an available building on Södras industrial area (Saw mill & Pulp mill), which was completely renewed and upgraded. The size of the CLT panels is limited to 12 m x 3,0 m x 0,36 m. In the same building is installed also a CNC router to machine the ready pressed CLT elements. This is the first complete Turnkey CLT Line delivered to Sweden. After commissioning is completed the plant goes into test production.
The complete line is integrated under the X-Lam manager developed by Ledinek Engineering.
A PC based master computer system for production management, production flow control and visualization, statistics, instant information’s and production analysis tools.
