LEUCO was able to improve the tine quality and increase the service life on the continuous finger jointing system at Schneider, with a “tailor-made” geometry. The Schneider Group is a complete supplier for modern timber house construction, explains Lukas Bärsauter, who is responsible for quality management: “We produce everything from glued timber to insulation, especially ceiling elements made of glulam or CLT.” The sawn timber required for this comes from our own cuts and is closed With finger-jointing, you really have to be able to imagine everything, explains LEUCO segment manager Markus Schindhelm, especially fluctuating wood moisture: “When finger-jointing, drier wood behaves differently than moist wood.” What could lead to differences in the tines: “So you have to look at the tip profile. Since Schneider is a continuous system, the boards are taut, but still have a certain tendency to give way. The course of the tip can thus be different from the moment the cutter enters until it exits. That in turn can lead to a different base game and problems with the fit. “
“When we were then sure that the geometry worked well for Schneider and that both the quality of the tines and the throughput of the system had been significantly improved, then there was another step,” summarises Schindhelm: “We said okay, the ‘Schneider Geometry’- which we also called that on our drawings – works, but the service life is not yet at our usual level. “But that didn’t seem to be a major problem for LEUCO: “We then decided to equip the tool with a coating and thus were able to improve the tool life.” Even so, remembers Schindhelm: “Originally, the milling cutters had to be replaced twice a week Now it’s several weeks, I think that currently a cutter change is only necessary every nine weeks.
Above all, things have to be done quickly in the production of finger-jointed lamellas for the industrial manufacture of glued wood and solid wood panels.
