With a market that continually leans farther away from five-part wood doors and a world around us that&#;s desperately looking for clean surfaces, edge-banding is becoming hotter than ever. But applying banding can create a bottleneck in shops that aren&#;t set up adequately for higher volume. In response, manufacturers are creating new forms of work cells that rely heavily on robotics and sensors to create workflow paths that streamline the process.
For example, SCM Group (scmgroup.com) is helping woodshops integrate edge-banding machines into cells that are fitted with rollers, panel return devices and automatic loading and unloading systems. These are often assisted by robots and fitted with IoT sensors to instantly control the machine functions. The company&#;s Stefani cell H is a state-of-the-art edgebanding and square-edging cell that&#;s fitted with an automatic panel feeder system. It also has an external milling unit to size panels, and a display in the operator&#;s area that shows how to position the panel so it can be correctly machined. It can process batches ranging from a single panel to damaged panels and the standard pack without the need for any production downtime to change the format, thickness, ornamentation and gluing quality.

Beyond building better cells, there&#;s a tidal wave of webinars in these post-pandemic times. Many discuss edgebanding, and some of those can be really useful for shop owners. If you haven&#;t participated in one, a webinar is just an online session that includes a select group of viewers who have the ability to ask questions in real time. One of the most discussed edgebanding topics right now is the ability to create a bond with no visible glue lines. Traditional edge joints have a tiny line between the tape and the adjoining face that can fill up with dirt and bacteria over the years. The gap is as wide as the glue layer is thick. Sometimes edgebanding becomes brittle and starts to chip, revealing more of a gap. Zero-joint edgebanding eliminates any gap by filling the space with a malleable layer that delivers the look of a monolithic (one-piece) door, drawer front or counter edge. The interior design market demands this cleaner, seamless joint on contours and edges, and thankfully that has become an attainable goal because of new methods and products. Essentially, the woodshop (or for smaller shops the outsourcing supplier) uses a hot air, laser or NIR bander to melt the filler, which the industry describes as &#;a co-extruded polymer functional layer&#;. Yup, it&#;s plastic.
FusionEdge from Ontario based Doellken (na.doellken.com) is one of many new edge-bandings that can be applied so that it shows no evidence of a joint. The secret, according to the manufacturer, is that there&#;s &#;a premium functional layer (which is a proprietary, pre-applied glue) that is consistent and color coordinated with the edgebanding&#;. The glue matches the band color, and can even be made to match grain. The system works with hot air, laser and infrared bonding technologies, and it is available in solid colors and wood grains.
Biesse N.A. (biesse.com) has its own answer to the invisible glue line &#; going glue-less! The company&#;s new Ray Force system uses infrared lamps (actually NIR, or near infrared rays) to fuse a reactive layer between the substrate and the banding. It works especially well on curves, as it is applied using an easily removed contour edgebanding unit that has been designed for Biesse Rover A, B and C edge machines. The technology can considerably reduce production costs when compared to standard glue-based methods because it requires no maintenance, there&#;s no clean-up and the time spent waiting for glue to warm up is eliminated. On top of all that the process means is more environmentally friendly. Compared to laser technologies, Biesse says that Ray Force requires a much smaller investment and is also much easier and safer to use. And unlike laser technology, it can be quickly switched back to traditional EVA or PUR glue with just an easy manual equipment change. The bottom line on Ray Force and NIR is that they eliminate having to apply conventional hot melt glue and the accompanying glue pot maintenance, while still delivering an excellent bond.

The new powerEdge Pro Duo from Homag (homag.com) was designed with the latest in sensors and control algorithms, and the result is a machine with an intelligent control system that defines speed, temperature and contact pressure at every point on the contour. In most cases, no manual fine adjustment is required. It has edge positioning and 360-degree gluing, where the start and end of the edge are positioned precisely, even on the smallest components. It also comes with a genuine combined function for zero joint or hot-melt glue application. The unit can do both, with no conversion required. The hot air nozzle for reheating the hot-melt glue also activates the functional layer of a zero-joint edge.
Ltronic is a new laser edging unit from Holz-Her&#;s Lumina series (holzherusa.com), and it, too, has a NIR module on board. The machine&#;s design makes it possible to change over from the Ltronic to a traditional Glu Jet unit in less than five minutes, using a very precise HSK interface. The Lumina has an automatic attachment recognition feature, so it knows when a change-over occurs and is ready for use immediately afterward. The change-over uses two special carts that were designed by Holz-Her that can be conveniently rolled up to the machine and docked on the guides. Then the HSK lock is engaged, the power supply is connected using quick-release connectors, and you&#;re up and running.
Ltronic doesn&#;t require heat-up and is ready for operation at the touch of a button. It operates without any noise emissions whatsoever, and without compressed air. The wavelength of the NIR module is very close to the intensity of the diode laser, allowing it to optimize energy with the utmost precision over the entire length of the workpiece. And no energy is lost between workpieces. There&#;s a database onboard with all the latest co-extruded and subsequently coated types of edging already stored for simple selection by the user. Each laser edging requires a specific quantity of energy, depending on factors such as edge thickness and color, and the unit automatically sets those as needed.
Another interesting new direction for woodshops that paint their edgebanding to match doors is a program being offered by RAMS Ind. in Arthur, Ontario (ramsindustries.com). RAMS sells thermoplastic edgebanding, hotmelt adhesives and technical profiles for the woodworking industry. The company has created a new program where it provides banding that exactly matches some of the most popular Benjamin Moore cabinet paint colors, and does so in both hue and sheen. With this, a woodshop no longer needs to sand, prime or paint edgebanding to match the door color.

PUR adhesives are essential to the edgebanding industry, but they give off emissions called diisocyanates. According to the American Chemistry Council, these &#;are organic compounds containing two isocyanate groups&#;, TDI and MDI, which affect the respiratory tract. Both chemicals have been shown to be portal-of-entry toxicants, and to cause a decrease in respiratory rate in mice and rats. The council notes that among other negative effects, &#;MDI and TDI-related occupational asthma can occur from overexposure in the workplace.&#; As a response, Henkel Adhesives (henkel-adhesives.com) has created Technomelt MicroEmission (ME) PUR adhesives for the furniture industry. This is a PUR adhesive range that contains less than 0.1 percent of monomeric isocyanate, and as such it is exempted from workplace environmental restrictions and doesn&#;t require any additional training or safety measures other than those currently in place. We&#;re going to be hearing a lot about ME PUR over the next few years from Henkel and other glue manufacturers.
Speaking of PUR, a new edgebander from Cantek (cantekamerica.com) comes with a state-of-the-art PUR glue pot. The machine is called the MX370PUR, and its PUR glue system has many advantages over older machines including a precise and thin glue joint, high heat resistance, and high moisture resistance. It comes equipped with working units including high frequency end trim, high frequency top and bottom trim, high frequency corner rounding, PVC scraping and a buffing station.
The Altendorf F5 edgebander also has an easily exchangeable and cleanable glue pot. machine (altendorfgroupamerica.us) comes with a lot of options from a 10&#; touchscreen with memory function to a pre-milling station, a trim saw, top/bottom trimming, a radius profile scraper, a corner rounding unit, a surface scraper and a buffer unit. It&#;s pretty speedy (22 feet per minute), and it can also be fitted with a practical multi-radius profile scraper.
One other timely note: the pandemic has generated a renewed interest in metal surfaces that are naturally antibacterial, and DC Distributing (dc-dist.com) has now developed a substantial collection of metal-coated edgebanding to support that need. The company&#;s MKT Alpha-Tape is ABS covered with real metal foil, to give the look of aluminum, stainless steel, polished chrome, or brushed gold/brass. DC stocks this banding in half, one and two-millimeter widths.
For smaller woodshops, several manufacturers offer edgebanding machines with budgets in mind. Castaly&#;s EB-1SC is one of seven machines that the company (castaly-cncmachine.com) offers in this category, and it&#;s a manual edgebander with a MSRP of $6,290. There are four larger automated machines in the catalog, too.
The Felder Group (felder-group.com) also offers an entry-level machine, the ForKa 200 ECO Plus, that can handle workpieces up to 2&#; thick. The company lists eight machines in the category that cover just about any sized shop&#;s needs.

At the XYLEXPO trade fair, HOMAG&#;s edging experts presented High-tech edges.
At the XYLEXPO trade fair, HOMAG&#;s edging experts presented:
&#; Batch size 1 production for flexible furniture production
&#; intelliGuide operator assistance system on edge banding machines
&#; Three edge banding processes on one machine
&#; Flexibility via 3-profile technology
&#; High-tech edges with integrated workpiece handling as part of a stand-alone workshop.
All HOMAG edge banding machines were displayed in Hall 3 with a new, modern machine design and a new name: EDGETEQ.
Batch size 1 production for flexible furniture production
HOMAG presented an innovative system concept for processing batch size 1 and small series in furniture production. The EDGETEQ S-810 edge banding machine with automated return was a winner with an optimally aligned all-round solution: For edge processing, the EDGETEQ S-810 is highly flexible thanks to edge gluing with automatic change between laser and PU. During operation, the cell can be used as a separate island or can be integrated in an automatic material flow. The cell includes a feed that supplies the machine from stacks. To increase performance, workpieces can also be handled in pairs. The machine operator can feed in and remove small parts manually.
Technical highlights:
&#; Processing of workpiece formats up to mm x mm
&#; Dimensioning in batch size 1 via the WZ14 workpiece supply system
&#; Edge gluing with automatic change between laser and PU
&#; Edge magazine for 24 rollers
&#; Post-processing of edges with servo technology for three profiles
&#; Two grooving units with horizontal and vertical servo axes and automatic adjustment of the groove width on one of the units
intelliGuide operator assistance system: Now also on edge banding machines
What started with the intelliGuide intelligent operator assistance system for panel dividing technology has now been adapted by HOMAG for edge banding machines. On panel dividing saws, the operator assistance system reacts intelligently to the actions of the saw operator. For example, intelliGuide flexibly changes the cutting sequence if the user feeds a different part into the saw than the one intended.
Where the operator assistance system is used on edge banding machines, two LED strips in the area of the workpiece infeed clearly show what the operator should do. This is achieved by the workpiece dimensions being displayed on the LED strips. The strips light up in different colors, thereby providing specific handling instructions.
&#; White LEDs show the workpiece dimensions for length and width. This ensures that the operator knows exactly which direction the workpiece should be inserted in. The position of the barcodes is indicated with green LEDs.
&#; If the workpiece passes through the machine several times for edging on multiple sides, the orange information color indicates which edge has already been processed.
&#; The blue information color appears as soon as there is an error message.
All of this means that with intelliGuide, incorrect processing of workpieces is almost completely impossible.
The benefits at a glance:
&#; Increased efficiency due to a reduction in the number of missing parts
&#; Increase in operating comfort for the operator
&#; Intuitive operation of the machine
&#; High level of process security
The all-round worry-free package for edge processing: EDGETEQ S-380 profiLine
At XYLEXPO, HOMAG demonstrated its full-flexibility offering for individual interior fittings in the form of the EDGETEQ S-380 profiLine. This system gives SMEs the ability to respond extremely flexibly to the requirements of their end customers. The first special feature is demonstrated as soon as the workpiece is inserted &#; there is an air cushion table that makes it easier to insert large or heavy workpieces. A belt-type top roll pressure is used for workpiece transport. This clamps the workpieces and is ideal for transporting high-gloss and sensitive surfaces.
In the magazine, the user has the choice between glue application with a gluing roller and the airTec procedure for manufacturing the zero joint. Even those who manufacture furniture for bathrooms, kitchens and laboratories will find a handy solution in this system: The machine is fitted with a PUR pre-melting unit that uses 2-kg cartridges.
The EDGETEQ S-380 profiLine is highly automated, a feature that is particularly apparent in the post-processing units. The trimmer, contour trimmer and scraper can be adjusted simply by touch. This minimizes machine set-up times and supports easy reproducibility, guaranteeing reliable quality at a consistently high level. The post-processing units also feature multi-tools that allow you to choose between two different radii simply by touch. No need to open the hood, no replacing the changing heads, and therefore no interruption of work.
High-tech edges: Flexibility3 with integrated workpiece handling
The EDGETEQ S-500 profiLine can be fitted with any options, is efficient and can be used with all types of material. The edge banding machine presented new possibilities at the XYLEXPO trade fair: Flexibility.
New: Three ways of banding edges on one machine
For those who need to change their edge-banding process&#;PUR, EVA or airTec zero joint technology&#;at frequent intervals due to the diversity of their product range, all three edge banding processes can now be performed using a single machine. In addition to the airTec unit, the machine is also equipped with two pre-melting units for PUR and EVA. This means that inexpensive EVA can be used on numerous body components, while PUR can be used where there is a requirement for resistance to temperature or moisture. The airTec zero joint process comes to the fore when appearance is particularly important &#; for example, when producing front pieces. Automatic switching between processes, without the need for manual intervention, saves both time and money.
New: 3-profile technology on the EDGETEQ S-500 models
This new 3-profile technology is the ideal solution for anyone looking for ways to increase their productivity. It changes quickly and automatically between three profiles and 20° chamfer with high repeat accuracy. The &#;3-profile technology package&#; includes a fine-milling unit (MF21) for three radii, 3-profile head for profile trimming unit FK30 and a profile scraper (MN21) for more than three radii. In the standard version, the following radii will be supplied: R1 = 1.0 mm, R2 = 1.5 mm and R3 = 2 mm.
The EDGETEQ S-500 profiLine features equipment for solid wood and high-gloss processing, as well as for processing parts with hinge holes (nesting package). It works at feed speeds of 16&#;25 m/min. The fully automatic flow of parts on display at XYLEXPO is made possible by the workpiece return LOOPTEQ O-600. Networking functionality is provided by the woodFlex cell control system. So that the edge banding machine can process each workpiece correctly, each part is given a digital identity (barcode) beforehand.
