EdgePro

EdgePro is a coating head for edge banding of workpieces. The application head achieves high-quality gluing with uniform, repeatable adhesive application, and clean cut-off. EdgePro allows a quick and flexible adaptation to workpiece thickness, is easy to clean, and thus contributes to increased productivity.

The EdgePro can be used to process EVA and polyolefin hot melt adhesives as well as PUR hot melt adhesives for thermally resistant and waterproof gluing with a viscosity of 10,000 to 100,000 mPas. The EdgePro coating head is mainly used in the wood industry for edge banding.

Advantages of the EdgePro Coating Head – at a Glance
  • Precise and repeatable adhesive application with clean cut-off characteristics
  • Uniform adhesive application across the entire edge length and width of the workpiece
  • Improved productivity and production flexibility thanks to quick adaptation to new workpiece thicknesses
  • High availability and low cleaning effort due to integrated filter and the possibility to close the nozzle completely
Precise and Repeatable Gluing

The coating head applies the hot melt adhesive in a controlled manner. A sensor scans the plate. The adhesive is applied precisely from the beginning of the workpiece to the end, repeating accurately and in the desired quantity. The optimized nozzle geometry ensures uniform distribution of the adhesive across the entire width of the workpiece. The negative-closing switching element achieves a clean and precise cut-off and thus reduces contaminations at the nozzle. Design and performance ensure consistent quality and high-quality gluing results.

Flexible and Efficient Production

The slim design ensures a straight-forward installation in new and existing systems. An optional mounting bracket allows easy positioning of the coating nozzle relative to the workpiece. The slot-type nozzle can be continuously adjusted up to 65/105 mm for the desired plate thickness (workpiece thickness) and thus offers high production flexibility. The nozzle width can be adjusted quickly and precisely to an accuracy of 0.1 mm using the handwheel and display. Automatic adjustment is offered as an option. Maintenance costs are reduced to a minimum thanks to an integrated adhesive filter that prevents nozzle blockages. The complete closing of the nozzle during extended interruptions also prevents the curing of reactive hot melt adhesives in the nozzle gap.
