In order to process as much lumber from the company-owned sawmill in Lauterbach/DE as possible in-house, Pfeifer from Imst/AT is entering the field of cross-laminated timber (CLT) production. "We see considerable demand in this young market and want to professionally increase the value added through this high-quality product," explains managing director Josef Dringel. For efficient and economic processing of raw panels, the company approached Hundegger from Hawangen/DE: Two processing centers by the joining experts are pending delivery. Timber-Online was invited to be present at the preliminary acceptance test. The first finished panel from the fully automated processing station is expected in July.
Without rotating the large but still delicate elements, the UFA processing center at Pfeifer in Schlitz/DE will henceforth take care of all six sides of the CLT panels. Two chain conveyors position the panels by means of the patented "Hundegger Motion Control" measuring devices in a precise and gentle manner. Furthermore, triple measuring is employed: on one position upstream of the processing stations and two downstream. "This way, we play it safe and make sure that no continuous grooves interfere with the measuring procedure," Hundegger panel expert Benno Hebel explains. Elements are put through five stations to receive splinter-free millings as well as cutouts at surfaces, front ends and long sides in one fell swoop. For particularly deep drillings e.g. for installation tubes at the horizontal level, the new system is equipped with a deep-hole drill.
"One big advantage of our machines is the in-house software," panel processing machine expert Herbert Gaissmaier explains. "After all, Pfeifer did not simply want to produce in a 'whatever works' kind of way but efficiently, reliably and automatedly. This can be achieved with the two processing centers since they support a continuous flow of information from the preparation phase all the way to machine setting."
"The UFA for Pfeifer is designed in such a way that they can produce 50,000 m³/yr for starters," Hebel elaborates. "If required, the company can upgrade the modular system and double capacity." The PBA offers similar options, Gaissmaier adds: "If the six equipped units with circular saw, chainsaw, drills and milling cutters reach their limits despite the integrated automatic tool changer with 17 seats, an additional one can be added here as well." "Of course, we expect to reach this point in the near future," Dringel adds with a smile. "But the option to start out smaller and therefore with less risk actually suited us very well." The Pfeifer team is very pleased with the successful collaboration and is looking forward to the system launch. Hundegger, on the other hand, is proud of convincing such a renowned customer of its products.
