WEINIG finger jointing lines: The fastest way to create higher value
Finger jointing is recognized as the most stable method of wood length joints. And if you require this technology, there's no better exponent than WEINIG. We are the specialists and have been number 1 on the market for over 25 years. WEINIG finger jointing technology is focused on maximum precision. This means minimal dimensional allowance, wood losses and operating costs. All systems are extremely user-friendly. This makes residual wood processing and upgrading by finger jointing profitable and easy for you!
The flexible modular design allows machines to be equipped according to your individual requirements. This enables high flexibility for standardized as well as customer-specific solutions, regardless of whether the systems have raw wood entry lengths, smaller or larger than 1,000 mm. The principle can be used for all performance classes: From the ProfiJoint entry model to the Ultra, CombiPact and Turbo-S models up to the high-performance class with the HS120 and HS200 horizontal finger jointing lines. In short: WEINIG system concepts are designed to meet the highest demands in quality for all performance classes.

The more challenging the better
The Louis Vuitton Museum in Paris is a veritable feast for the senses in steel, glass and wood. The planning and design required boldness and inspiration. Precisely the right kind of challenge for Mathias Hofmann and his company Hess Timber.
Louis Vuitton is renowned worldwide as a manufacturer of exclusive luggage, handbags and champagnes. Behind the brand is France's richest man Bernhard Arnault. An art lover who recently commissioned the construction of the museum of the Louis Vuitton foundation in the south of Paris. The plans were drawn up by renowned North American architect Frank Gehry. Costs were not high on the agenda and the individual works were subject to the highest demands in quality and creativity.
Mathias Hofmann and his company Hess Timber won the tender for the timber sections of the winding and sophisticated roof structure comprising 12 sails. "The more challenging the better. I love such projects," says the man from Kleinheubach, Bavaria, of his philosophy. With his unconventional thinking and bold attitude to risk, Mathias Hofmann has earned a lofty status in international timber construction engineering. He somewhat regrets that his highly competitive day-to-day business, building supporting structures for standard buildings, has taken something of a back seat. The costs for major projects are high. "Each time you need practically new technology," he says. This was also the case for the Louis Vuitton Museum. The ridge girders required, partly comprising two arches, were produced on an in-house press bed. The client was impressed during the tender process by Mathias Hofmann's unusual style of rod-based block gluing. The highlight is a rod cover lamella that has the same visual appearance from above and below as from the sides.
That transporting the laminated beams, which are up to 28 meters long, through the Parisian metropolis did not cause chaos is attributable to another unorthodox idea of Mathias Hofmann – Hess Limitless. The procedure is based upon a special adhesion geometry and, in principle, enables girders to be transported in short, individual segments without length restrictions or loss of bearing capacity. The girders are then put together at the construction site. Mathias Hofmann can rely on excellent partners in WEINIG. Defects are cut out by an OptiCut at Hess Timber. Two PowerJoint systems take care of finger jointing the lamellae. A Powermat then planes the workpieces ready for gluing. "I have never regretted opting for WEINIG," says Mathias Hofmann.

Top quality glulam in seconds
At Weinberger in Austria, a glulam lamella is jointed every two seconds. However, output is not the prime objective. It is quality that counts.
Weinberger Holz in Abtenau recently commissioned a completely new system concept for glulam production. Two high-performance compact systems from the WEINIG GreconLine provide output of 30 longitudinal joints per minute. Normally, one strand is responsible for the flawless top layer and a second for the central layers. However, if the top layer is proportionally small, e.g. in the case of thick girders, both machines joint central layers. Second highlight: Since the finger jointing is only performed by one cross-cut saw, a WEINIG OptiCut Quantum 450, both top and central layer quality can be processed without a larger buffer of raw wood.
By extracting flawless parts from the raw timber, Weinberger has increased its surface quality to "unprecedented levels" in its own words. The "completely open construction on one side" was first used when finger jointing on both PowerJoint 15 machines. The wood is transported via cross conveyor directly into the processing area, where it is simply finely positioned before jointing commences. Weinberger is certain that compact systems have significantly higher pressing quality compared with extrusion presses. The individual clamping reduces jointing offset. A top priority for the quality-driven Carinthians.
No regrets about using outsiders - the Dauerholz story
Peter Weller says: "If I want an entire concept, there is no alternative to Weinig."
The idea started in Hamburg. The production was outsourced to MeckPom. Using outsiders has really given the company a boost. But the Dauerholz decking boards are an obvious hot topic.
A few years ago, a Hamburg carpenter made a sensational discovery: Unlike similar preservatives, hot wax seeps into the core of the wood ensuring genuine deep protection. The researcher found bold investors who believed in the idea, primarily because the outdoor area, with decking and construction timber, provides vast scope for ecological wax-impregnated wood with its high resistance to weathering, moisture and pest infestations. A production plant was built in the perfect spot in Dabel near Schwerin.
The customized Dauerholz production line was designed and installed in close cooperation with the project specialists at Weinig Concept. As well as a planing and profiling machine, a high-speed optimizing cross-cut saw, a curve cross-cut saw, a scanner and a finger-jointing line, the site also includes a tool grinder machine from the Weinig portfolio. “We wanted to keep the entire process in-house as well as being completely autonomous in terms of tool preparation,” says Peter Weller, explaining the decision.
Dauerholz placed greatest emphasis on optimization of wood recovery and finishing. We performed a recovery analysis and established that we had more than halved cutting losses, reports Peter Weller. This success is also partly attributable to the new moulder. The moulder is equipped with “floating” vertical spindles whose flexible bearings allow it to follow the natural curvature of the wood over long lengths. This prevents “snipes” and “dips” on either end of the work piece and eliminates finish planing with further chip removal.
Intelligent feat of strength
The glulam lamellae at Pfeifer in Imst, Austria, are pressed at 160 m/min and subsequently planed. The throughfeed press replaces four old machines.
The Pfeifer group commissioned its modernized production facilities in Imst at the start of 2013. Performance and wood savings were decisive in awarding the order, recalls authorized representative Dietmar Seelos. "We required a press with a feed speed of 160 m/min." This feat of strength was necessary because the new single pressing line was replacing four existing lines. The company chose a WEINIG DKK 115 through-feed press. Its role is to create a continuous strand from the pre-milled and glued infed timber. A feed unit accelerates the lamellae and transports them to the feed-in station, where they are handed over to two servo-controlled, synchronous aligning chains. This ensures continuous jointing with no offset. The master computer knows exactly which infeed lengths and cross sections are coming to the press. The DKK 115 adjusts itself automatically. At the end is a continuous flow of glulam lamellae, which is pushed relentlessly towards the planing. This is a special case as the feeding power of the DKK must also be sufficient for downstream planing. Two 90 kW electric motors are therefore used. The improved chip removal of the WEINIG planer proved decisive. The Powermat 2500 saves at least one millimeter. Since the Kundl sawmill invested in the same planing technology in its quality sorting, it has benefited from the combined effect of the two machines. Performing the cutting in its own sawmill also allows the smaller input dimensions to be reflected one-for-one in the cutting dimensions. For a glulam factory with an output of 100,000 m3/year, this represents an enormous saving.
