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.

"First you must understand what you want"

Tiger You, founder and Managing Director of Tiger Excellent Wood Sdn Bhd

The man behind the desk has a striking name and is an equally striking personality. Mr. Tiger You is part of the furniture at this Malaysian rubberwood company.

Tiger Excellence Wood in Malaysia produces furniture parts from rubberwood, the Asian plantation wood. The raw material is provided by the company's own plantation. The residual timber is sold to a wood chip producer. A long value chain that says much about the quality of the company. Higher manufacturing productivity and independence from suppliers have long been on the wish list of owner Tiger You. He particularly wanted greater efficiency in the labor-intensive sorting process for rubberwood with its many shades of color. This is a key factor for commercial success as consistent surfaces are the ultimate quality benchmark. Tiger You was aware that it would take time to implement his plans. “First you must understand what you want," he underlines. WEINIG Asia ultimately convinced Tiger Excellence Wood with a unique combination of a high-speed solution and two-sided assessment of the workpiece – a crucial unique selling point in the sector. The customized system is able to produce 125 parts per minute. The major components are an OptiCut Quantum 450 cross-cut saw, a specially developed automation system and a Matchscan scanner. The scanner is equipped with high-resolution color cameras capable of sorting 300 parts per minute into 6 different color shades. Downstream of the scanner is a spraying device that marks poor board sides for further processing. Tiger Excellence Wood is highly satisfied with the system's performance. "German machinery is worth the price," says Tiger You, adding: "Taiwanese machines may be cheaper but quality is not guaranteed. Over the long term, maintenance costs can even exceed the purchase price of a German machine."

Operation future

Minimal malfunctions and easy to use: CombiScan+ at JCE Chile

J. Christer Ericsson, founder of JCE Group, which takes his name, is a legend. A creative mind who could always spot future opportunities. When the former naval officer launched a second career as an entrepreneur, he initially remained faithful to his previous field. He enjoyed instant success with his idea of replacing the chains for loading ship containers with plastic belts. Another idea, namely building spectacular hotel platforms in open sea, earned him global renown. Today, JCE Group is an international investment company based in Gothenburg. The head office manages an enormous breadth of activities, which are characterized by progressiveness and sustainability. The group has maintained its links with the sea via offshore commitments in wind power projects. Another cornerstone is the wood industry. The group is a market leader in the chipboard plant and sawmill sector. In partners, they seek companies that can help them shape their innovative focus. WEINIG meets these requirements. JCE Chile S.A. acquired a CombiScan+ C 600 scanner for 4-sided detection with laser and color cameras, which is also equipped with X-ray sensors. The system is used for the production of finger-jointed goods and panels. Given that previous practices included marking with chalk, the technology heralds a new era in optimization for JCE Chile. The previous output of up to 22,000 running m/shift has been increased to 30,000. The company also invested in an OptiCut 450 FJ+ high-speed optimizing cross-cut saw. This achieves a timber yield of up to 6 per cent while the defect rate has decreased dramatically compared with the old cross-cut system. "Previously, cutting was a huge problem. Not now," report JCE.

Top quality glulam in seconds

PowerJoint power: Thanks to the open design on one side, 2 x 15 connections per minute

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.
