Called “an outstanding success,” the 2007 Ligna+ Fair featured displays by 1,879 exhibitors spread over 1.4 million net square feet of space in the Hannover Fairgrounds. The biennial woodworking show was held May 14-18 in Hannover, Germany.

“Attendance was up by over 10 percent, with a major increase in the number of high-caliber visitors and more guests coming from abroad than ever before,” said Stephan Kühne, a member of the managing board at Deutsche Messe, the show organizer.

International attendance in particular grew significantly, accounting for 46.5 percent of total visitors — 50,200 attendees — compared to 42.8 percent in 2005. Much of the growth came from Asia, North America and neighboring EU countries, with a 32 percent jump recorded by Asian visitors (5,800) and North America (4,500). The EU countries accounted for 28,900 attendees. According to show management, Ligna+ also drew a large amount of decision makers to the biennial fair. Visitor profiles show the number of decision makers at the show reached 85,900, or 82.3 percent of attendees.

“Ligna 2007 has delivered exactly the kind of stimuli needed for even more solid growth ahead,” Kühne said.



The next Ligna+ show will be held May 18-22, 2009. For more information, visit the Deutsche Messe Web site at www.messe.de.

Interzum Shines Light on New Developments

Light was the theme at biennial Interzum 2007, with hardware companies displaying ways to incorporate LED lights into casework, introducing mechanisms that allow drawers and cabinets to open with just a light touch and highlighting supplies related to lightweight panels.

LED lights, which feature low temperature and lots of color choices, brightened displays of companies like Häfele and Hettich. They provided ideas for adding a decorative touch in shelves, drawers, doors and furniture, with some applications showing functionality as well — lighting the interiors of drawers and cabinets. Light strips and sheets also gave an attractive glow to kitchen and bath displays.

With the soft-close feature now prevalent in the majority of drawer slides and hinges, the new introduction in functional hardware was mechanisms for “handle-free” opening and closing of drawers. Most showed three different configurations: a totally mechanical system, partly mechanical and partly electric, and one that is totally electric.

With the total electrically driven systems, drawers and doors will open and close automatically with just the lightest touch anywhere on the drawer front. The combination and totally mechanical systems require a little more pressure and also may require the push to be in a specific spot on the front. But in all cases, the result is a bank of drawers or cabinets visually unmarred by knobs or pulls.

Honeycomb Panels Create a Buzz

Creating interest across the show floor was the introduction of products for lightweight panels. Offering strength with minimal weight, honeycomb panels reportedly soon are to be incorporated into mass-produced casework. Several hardware manufacturers at Interzum displayed products designed for use in lightweight panels.

Surfaces Go for Natural Look

Also popular at Interzum were panels and surfacing materials in realistic woodgrains and stone patterns, a trend spurred by advancements in printing technology.

Lamigraf, for example, recently added a new printing machine to do five-color printing, expanding the quality of woodgrain replication. There also are continued refinements with embossing and other techniques to provide the tactile effect of real wood. In an innovative twist, Suddekor’s “Fragrance Foil” process adds scents to the varnishing process, so the finished product releases the smell of a species.

With regards to species preferences, American walnut and bamboo were the most-mentioned “hot” sellers. Producers of surfacing materials also said dark woods like wenge are still popular, as are exotic looks, such as rosewood and zebrano — mixed with warm fruitwoods, like pear, apple, plum and cherry. Tom Drazen, North American sales manager for Schattdecor, said, for example, that a popular look is to pair a “plain” fruitwood on kitchen cabinets with an exotic, like jatoba, in the floor.

While wood predominated, other materials, such as leather, were shown in interesting ways. For example, Hornschuch showed a prototype of its Skai vinyl film in “alligator” used on a cabinet door. Julius Blum showed a prototype kitchen drawer with a leather bottom and sides. Also unique was Stone-Veneer, a paper-thin real stone surface introduced by board producer Richter Furniertechnik. — Helen Kuhl

Among the products displayed by the Weinig Group, the Multipower added-value moulder processes workpieces lengthwise and also can be used for end profiling. Workpieces are tensioned pneumatically and fed past the tool manually. The end slide can be tilted at an angle of up to 60°, so even miter profiles do not pose any problems. CIRCLE 225

Also from the Weinig Group, the Unirex 2000 CNC-controlled drilling center with integrated crosscut saws is for drilling and milling of window and door components. CNC collets enable the complete processing of planed wood in a clamping device from all sides, Weinig says. CIRCLE 226

Part of the Weinig Group, Raimann presented the SpeedRip 600, a new generation of high-performance, multi-blade circular saws for processing more than 20 boards per minute. CIRCLE 227

Dimter, a subsidiary of Weinig, displayed the OptiCut 45 throughfeed cutoff saw for high-production applications. The OptiCut’s VarioSpeed infeed system reduces the gaps between boards and allows the saw to cut without interruption. HighGrip feed rollers ensure effective gripping to transfer the board with high acceleration and deceleration rates. CIRCLE 228

Grecon, also of the Weinig Group, presented the CombiPact fingerjointing line for vertical and horizontal profiles. Features include a double milling cutter unit, glue feed with integrated wear-resistant glue pump and touchscreen for setting the press. CIRCLE 229

Available from Solid Wood Systems, the Balestrini Fox-T CNC tenoning system for chair manufacturing features 4-axis interpolated tool movement and positioning of seven axes, with user-friendly interfaces. CIRCLE 230

Martin presented its T27 FleX shaper with a tilting range of 2° by 46° for easy setup of complex moulding patterns. Cutting height and angle are structured for the operator. After activating the tool, the controller will indicate the location to reference the tool in relation to the table and fence jaws. CIRCLE 231

Martin also displayed the T60 PreXision sliding-table saw with a tiltable blade of 46° to the left for a total cutting-agle range of 92°. The maximum cutting height is 72mm and the maximum blade diameter is 315mm. CIRCLE 232

Ogden offers the Neva Orbit thin-cutting frame saw, featuring a new up-and-down method of movement for cutting lamellas/veneer slats. During the downstroke, the cutting motion is lineal. At the bottom of the stroke, the saw frame swings out of the cut in the same direction as the wood is moving. Once the saw frame has retracted from the cut, the frame then travels back to the top, remaining out of contact with the wood. CIRCLE 233

Atlantic Machinery offers the Paolini T160 and TX160 heavy-duty five-speed shapers, available with or without tilting-spindle capability, sliding table or tenoning table attachment. Other features include a unique adjustable table opening for cutters and a tilting fence assembly. CIRCLE 234
