Finger jointing line for Stora Enso new CLT production in Zdirec
Mr. Herbert Jöbstl, Head of Operations, Wood Product SE:
“As in many previous projects, Ledinek has once again demonstrated its competence and reliability in the supply of plant-areas for our CLT plant in Zdirec.”
For our customer Stora Enso, who have already built their fourth CLT line, we have delivered for about a third of the whole equipment for their new project in Ždirec, Czech Republic. The Ledinek plant consists of the infeed equipment, which represents the first part of mechanization and delivers wood to our machines for cutting out the defects (X-CUT S400) and for finger jointing (Kontizink H 5000).
The second part of the mechanization belongs to our planer Superplan 4V-S250 and delivers wood to the machine and after the planer to the press for single-layer panel production. Both the mechanical and electrical installation were completed according to schedule, and we thus also started test production on time, which was an important milestone for both the Stora Enso and Ledinek teams. This will now be followed by the optimization of production and the training of the operators at the plant.
As well, we delivered to the customer two feeding machines Powerfeed 70-S350 and the Superplan 6VR-S350 planing machine for their sorting line. The equipment is in the commissioning and testing phase.
Despite all the challenges we had to overcome over the past months due to the epidemic and extended delivery time for material, the project is progressing well, and we are looking forward to finishing it successfully. The biggest credit here goes to the Stora Enso and Ledinek teams and their good cooperation on the project.
We wish the Stora Enso team all the best and a lot of success with their new investment.
