timber per year. Extensive experience and the level of commitment on the part of suppliers such as Kallfass ensured the success of the project.
The latest and, simultaneously, largest sawmill in the Juodeliai Group is currently operating in Marijampole in Lithuania. The largest sawmill group in the country encompasses four locations and is responsible for cutting more than 1.3 million solid cubic metres of logs per year. Juodeliai aims to produce around 650,000m3
of pallet timber in
2022, generating over €200m in turnover as a result.
With customers in over 40 countries, the company is highly export oriented, although, according to CEO Andrius Zimnickas, no business relations are cultivated with Russia or Belarus, despite their geographic proximity. The company mainly obtains its spruce and pine logs and, also, hardwoods from Lithuania, a fact that also makes Juodeliai the largest consumer of timber in the country. The company commissioned a fourth sawmill in 2020 in Marijampole, about a two-hour drive west of the capital Vilnius. Designed for an annual capacity of 250,000m3
, Juodeliai also produces pallet
timber there for the global market. When it came to machine suppliers, the company opted for proven plant solutions from companies such as Linck, Holtec, Microtec and Kallfass. The latter is responsible for the mechanisation, sorting and stacking of main products and side boards. “A practical, solution-oriented approach is the main reason we are co-operating again with Kallfass,” said Mr Zimnickas.

vertical system transports the separated logs as a whole to a peel-off system. Aided by gravity, these form a veritable carpet of boards. After passing a visual inspection station, layers are formed and the boards are cut at both ends before being fed layer by layer to a stacker. Stacking then follows, with Kallfass laying the dispatch sticks automatically using stick magazines. Finally, Kallfass is conveying the stacked shipping packages to the strapping machine via a roll transport system.
Kallfass collects the side boards in buffer
levels. “As we had little experience with these short dimensions, the design was partially based on assumptions that, ultimately, worked out very well indeed,” said Matthias Link, Kallfass project manager.
SOLUTION-ORIENTED APPROACH This was neither the first nor the last joint project for Kallfass and Juodeliai. The German plant engineers had already been involved in a greenfield project for the Lithuanian timber industry in 2014. “We’re delighted to have opted again for Kallfass,” said Mr Zimnickas. “They never try to offer us prefabricated solutions, but rather concentrate on our ideas and implement these. This practical approach is the main reason we decided to work with Kallfass again.”
Mr Zimnickas added that the next project, a second main product stacking system for Marijampole, has already been commissioned. This will be commissioned in the first quarter of 2024 at the latest. ■
