Abstract
A building board is finished in a first processing station via laterally operating processing means, where-in a first edge strip is glued along a first edge side of body element of the building board. In a second processing station a primary surface layer is glued, by vertically operating processing means, to cover the entire primary main side and the primary side of the first edge stripe. Thereafter, a vertical pressure is applied over the body element and the first edge stripe across a working direction while the body element and the first edge stripe pass the second processing station in such a manner that a primary side of the first edge stripe is brought in level with a primary main side of the body element when passing the second processing station.
