Abstract

A device for coating surface portions of a board material with a liquid material. The device includes a wheel which transfers the coating material and compressed air which positions the coating material. A method for surface coating and a floorboard with a finished surface portion.

Claims

1. A device for coating a liquid material on a surface portion of a sheer-shaped blank comprising a core of wood or wood fibers and top layer, wherein the surface portion is machined such that it lacks the top layer, said device comprising a wheel and a compressed air nozzle, the wheel is arranged so as to transfer the coating material to the surface portion by rotary motion, and the compressed air nozzle is arranged to apply air to the top layer so as to move the coating material in a contactless manner using an air flow.
