New Hymmen Tech Allows Surface & Edge Finishing in One Pass

Bielefeld, Germany, March 24, 2026-Hymmen is introducing edge coating technology that closes the gap in the panel finishing process by covering not only the surfaces but also the edges in a single pass.

To meet customer requirements, Hymmen coating lines offer variable working widths and adaptable line speeds. Production speeds from 10 to 120 m/min can be achieved with ease, even at line widths of up to 3,000 mm. These capabilities make the systems suitable for a wide range of industries.

In a system designed for finishing the surfaces and edges of wood-based panels, the material passes through a process that can include various steps depending on the final product and explicitly incorporates quality control stations. A typical production sequence may proceed as follows:

• During infeed, the panels undergo an initial quality inspection before being transferred from the stack into the line via a “flying stack change,” which eliminates downtime between stacks. Depending on the materials to be coated, defects are then identified-on both faces as well as the front and rear edges-and subsequently repaired.
• Using belt conveyors, turning devices, edge brushing machines, and-depending on the layout of the production hall-angled transfers with buffer zones, defective panels are removed from the flow while A grade material continues through the process.
• In the first edge coating stage, the front and rear edges are coated; in the second stage, the longitudinal edges follow. This includes primer, basecoat, topcoat, and UV curing. The surface coating process is carried out in a similar manner.
• After coating, the panels are removed from the conveyor by the portal system and stacked with precise edge alignment on one of the two stacking roller conveyors.
