This means of application saves paint and the cost of cleaning up overspray. The technology also allows precision-control of spray volume, providing additional overspray protection when painting narrow edges, such as on kitchen and bathroom furniture. The paint application process is very fast, supporting production-line throughput rates of up to 100 m/min.
Robert Bürkle: new roller coating process
Pressing and surface finishing specialist Robert Bürkle (Hall 17, Stand F19) is doing its part to give furniture manufacturers greater flexibility and scope for product customization. At LIGNA, the company will be unveiling a new roller coating process. The process delivers reduced paint consumption and increased performance. Roller coating is commonly limited to flat work-pieces, but Bürkle has developed a solution that enables it to be used on formed, non-flat furniture parts with four paintable sides and tapered ends. The paint rollers are repositioned by means of servo-motors, and the system enables continuous coating without paint tearing. The process uses an intelligent transport system that feeds multiple work-pieces through the roller-coating machine in parallel while keeping them reliably in the correct position. A multi-axis robot is used to handle the cassette and rotate the work-pieces through 90°.

SAMES KREMLIN: Vortex atomizer technology for liquid coatings
SAMES KREMLIN (Hall 17, Stand A58) will be showcasing its innovative use of the vortex effect in spray painting. The technology uses special PEEK vortex inserts in the spray nozzle to generate a vortex (helix) in the atomized paint stream. This reduces the velocity of the paint particles, enabling the paint to more effectively reach hollows and cavities in complex-shaped work-pieces. This optimized wrap-around effect reduces the spraying time required, and the finer spay significantly reduces overspray, while the diffuser ensures superior paint atomization, resulting in a larger, softer vortex. The Vortex air shroud accelerates the paint particles in the same manner as an airspray gun, thereby improving the application of stains on wood.
SCM: 3D finishing effects
SCM (Hall 13, Stand A48) will be showcasing a comprehensive array of technologies and solutions for surface finishing. At the SCM stand, the focus will be on industrial solutions that can be used to produce a wide range of 3D finishes, including wave designs, hand-smoothed, embossed, saw-cut and wormhole effects, which have the power to spark authentic tactile and visual user experiences. The surface finishing solutions on display at SCMs Superfici stand (Hall 15, Stand C06) will include anthropomorphic and Cartesian robots for painting panels and fixtures, and an extensive selection of sprayer systems for a wide range of applications and production scales.
Venjakob: VEN PROFIT data analysis tool as system dashboard
Venjakob will be at LIGNA (Hall 16, Stand C22) with its VEN PROFIT solution – a data analysis tool in the form of a dashboard. The solution uncouples factory data capture from control platforms, thereby enabling the data to be stored in local networks or in the cloud. Interface adapters allow the same dashboard to be used with different control platforms and enable the captured data to be displayed and analyzed on different end devices. The dashboard can analyze and present machinery data in various different ways, so that users can, for example, monitor production processes, plan maintenance using predictive methods and use the data for management-level analysis.
WINTERSTEIGER: Surface finishing with TRC Manufactory
At this years LIGNA, WINTERSTEIGER (Hall 27, Stand F60) will demonstrate how its TRC Manufactory technology can create authentic rustic-style flooring with genuinely unique, non-repeating visual and tactile characteristics. Rustic-style flooring is ubiquitous and likely here to stay, but genuinely one-off rustic surface finishes are a rarity. Despite the use of natural drying methods, hand-finishing techniques and various other approaches, efforts to manufacture genuinely unique rustic floor planks are all too often foiled by telltale repeating visual and tactile features. The TRC Manufactory system finishes individual floor boards that have been repaired and filled. Each plank is individually scanned, analyzed and processed. The edges of the planks are rounded in irregular patterns, and grain patterns and knots are burnished so that they stand out from the rest of the surface.
