The invention relates to a press for pressing glue-coated wood chips for forming a beam having at least one substantially U-shaped cross-sectional portion. The press comprises a master tool (6), in which an elongate groove with parallel side surfaces is provided, and an elongate forming tool (7) which is vertically displaceable in the groove of the master tool. The side surface of the forming tool (7) and the groove (9) are located at a distance from another for forming a gap (10) between them and comprise each at least one carrier surface (11, 12) which is oriented in the pressing direction of the forming tool, a forming insert (13) which during pressing of the glue-coated wood chips, will move with the carrier surface (11) of the forming tool and contribute to pressing together the wood chips. During retraction of the forming tool, the forming inserts will be obstructed by the carrier surface (12) of the master tool, thereby disengaging the beam from the forming tool. The invention further relates to a method for pressing a beam having a U-shaped cross-sectional portion.
