Abstract: A device for manufacturing a tray of cellulose material, includes: a compression mold including an essentially flat bottom end and surrounding sides for compression molding and drying of cellulose pulp to a finished tray; a male mold arranged to fit into the compression mold and that includes a bottom space and lateral surfaces corresponding to the compression mold, wherein the compression mold and the male mold between themselves delimit a mold space including a base section and a side section for compression molding of the cellulose pulp. Both the compression mold and the male mold are provided with blow and suction devices for blowing in and suction of fluid in and out of the mold space. The blow and suction devices include an inlet pipe having an inlet valve, coupled to an inlet chamber in connection with the mold space, and an outlet pipe having an outlet valve separated from the inlet pipe and coupled to an outlet chamber in connection with the mold space.

Abstract: A method for producing a compression-moulded tray of fibre material, said tray being formed of fibre material in a compression method, from a suspension of mechanical pulp of cellulose. The formed tray is formed by press-drying using heat to a dry content of 80-95%, preferably 90-95%, and the fibre material of the formed tray has a density in the order of 400-650 kg/m3. The inside of the tray is provided with a protective barrier, said barrier being removable.
