Abstract:
1. A device for coating a liquid coating material on a surface portion of a machine fed sheet-shaped blank comprising a core of wood or wood fibers and a top layer, wherein the surface portion is distinct from the top layer such that at least a portion of the surface portion is displaced from the plane of the top layer, said device comprising: an angled wheel rotatably disposed relative to a container of liquid coating material, said angled wheel positioned for receiving a machine fed sheet-shaped blank such that rotary motion of said angled wheel is adapted to transfer coating material to the surface portion and to at least a part of a surface of the top layer of the sheet-shaped blank, and a compressed air nozzle disposed proximal the top layer of the sheet-shaped blank, said compressed air nozzle directing an excess of the coating material applied to the surface of the top layer of the sheet-shaped blank toward the surface portion of the sheet-shaped blank, wherein, when in use, the angled wheel transfers the excess of the coating material to the surface portion and to at least part of the surface of the top layer by rotary motion, and the compressed air nozzle applies air to the surface of the top layer so as to move at least the excess coating material applied to the surface of the top layer in a contactless manner using an air flow, and wherein the wheel has a rotational plane and, when in use, the air nozzle applies air in a direction substantially parallel to the top layer and towards the rotational plane of the wheel.
