Abstract: The invention relates to a device for manufacturing an OSB beam with a web and at least one flange. The starting material for the beam is wood strands of OSB type. The device comprises a feeder device for advancing the strands, a metering device for metering out the strands, a nozzle, through which the metered strands pass, and a receiving surface for receiving the strands. The feeder device, the metering device and the nozzle are adapted for applying strands to the receiving surface in the form of an elongated bead. The height of the bead is at every point of the cross-section substantially adapted to the web and flange of the beam being made. The invention also relates to a process for manufacturing an OSB beam and to a computer readable medium comprising a program.

Abstract: A press having oppositely arranged lower and upper master tools, at least one having an elongate pressing tool which is vertically displaceable in a groove in the master tool, and two lateral pressing tools arranged between the main surfaces of the master tools, on each side of the groove. The press also having at least two mold inserts, arranged on the pressing surface of at least one of the master tools, having the form of an elongate rod extending along substantially the whole of the longitudinal extent of the press and having a substantially U-shaped, outward-facing cross-sectional form, and which are displaceably movable, at least to a limited extent, along the horizontal pressing surface of the master tool transversely to a longitudinal extent of the press, and at least one partition wall arranged between the mold inserts on the pressing surface of at least one of the master tools.

Abstract: 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.

Abstract: The invention relates to a device for manufacturing an OSB beam (39) with a web (41) and at least one flange (43). The starting material for the beam is wood strands (17) of OSB type. The device comprises a feeder device (3) for advancing the strands (17), a metering device (5) for metering out the strands, a nozzle (7), through which the metered strands pass, and a receiving surface (9) for receiving the strands. The feeder device (3), the metering device (5) and the nozzle (7) are adapted for applying strands to the receiving surface (9) in the form of an elongated bead (37). The height of the bead is at every point of the cross-section substantially adapted to the web and flange of the beam (39) being made.
