Abstract
A board to be coated is conveyed by means of first transport means in the form of a roller conveyor to a curtain coating device. The latter comprises second transport means in the form of two conveyor belts, each of which runs round an associated straightening bar in the direction of transport of the board. The straightening bars are movable and as they move towards one another they align the boards at the side edges thereof in such a manner that the side edges extend approximately parallel to the direction of transport of the board. Conical rollers are connected to the straightening bars. During alignment, that is to say, when the straightening bars are moved towards one another, the board to be coated is at the same time lifted from the roller conveyor by means of the conical rollers and conveyed via the surfaces of the conical rollers to the conveyor belts. The latter engage laterally at the board edges and transport the board through a pouring curtain for the purpose of coating.
