Abstract: The present invention relates to a method and a machine for making a fibre product. The invention also relates to a shaped body produced by the inventive method. According to the invention, a fibre product is formed on a first tool. The formed fibre product is then sandwiched between the first tool and a second tool and the surface of the second tool is heated to at least 220° C. to evaporate water from the fibre product. The tools are permeable to air and water When the fibre product has been dewatered to a dry solids content of at least 70%, the fibre product is subjected to microwave heating.

Abstract: A fibrous panel is molded in two or more progressively formed mold members each comprising a porous support plate to which a plurality of rigid mold pieces are affixed. The mold pieces are truncated 3D tapered structures, and are arranged on the support plate in a regular array so that an intersecting grid or lattice of channels is defined between them. A fiber stock is poured into a first mold member and the stock is compressed and dewatered to form a panel. The panel is removed from the first mold member and placed into a second mold member having narrower and shallower channels whose side walls are more upright than those of the first mold member. The panel is further compressed and dewatered in the second mold member, and is densified in both the vertical and lateral directions by virtue of the progressive formation of the mold members.

Abstract: A method of producing a pulp molded article comprising the steps of assembling splits (10, 11) each having a suction passageway and a papermaking screen (5) into a papermaking mold (1), filling the cavity of the papermaking mold (1) with a pulp slurry, discharging the liquid component of the pulp slurry through the suction passageway to deposit pulp fiber on the inner side of the papermaking screen (5) into an undried wet molded article, and dewatering the undried molded article deposited on the inner side of the papermaking screen (5), wherein the splits (10, 11) each have a large number of flow passageways (2) for feeding a purging fluid for cleaning the papermaking screen (5), and the purging fluid is ejected from the outer side of the papermaking screen (5) toward the cavity through the flow passageways (2) during the filling with the pulp slurry.

Abstract: A papermaking mold for producing a pulp molded article comprising a core of prescribed shape which has a plurality of holes for fluid passage interconnecting the outside and the inside and is made of an elastically deformable material and a fluid-permeable material which covers the outer surface of the core, the fluid-permeable material being capable of forming passages for a fluid in its thickness direction even when pressed and deformed.
