    Abstract: A method and system for edge-forming cellulose products from an air-formed cellulose blank structure. The system comprises a first mould part having an edge-forming device with a protruding element configured for compacting and separating fibres of the cellulose blank structure and a second mould part arranged for cooperating with each other. The edge-forming device is movably arranged in relation to a base structure of the first mould part, and is adapted for interacting with a pressure member arranged in the base structure. The method includes the steps: providing the air-formed cellulose blank structure, and forming a compacted edge structure of the cellulose products by separating fibres of the cellulose blank structure with the protruding element, applying an edge-forming temperature, and compacting the cellulose blank structure by applying an edge-forming pressure onto the cellulose blank structure between the protruding element and the second mould part.

    Abstract: A method for manufacturing a molded body, includes a deposition step of depositing a mixture containing fibers and a starch in air; a moisturizing step of applying water to the mixture; and a molding step of forming a molded body by heating and pressurizing the mixture to which the water is applied. In the method described above, the starch has a setback viscosity (η50-η93) of 40 to 200 mPa·s, the setback viscosity (η50-η93) being obtained by measurement performed in accordance with the following measurement methods (1) to (4) using a rapid visco analyzer (RVA). The measurement is performed such that (1) after a water suspension containing the starch at 25 percent by mass is charged in the RVA as a measurement sample, the temperature thereof is increased to 50° C. and then maintained for one minute; (2) the temperature of the measurement sample is increased from 50° C. to 93° C. over 4 minutes and then maintained at 93° C. for 7 minutes; (3) the temperature of the measurement sample is decreased from 93° C. to 50° C. over 4 minutes and then maintained at 50° C. for 3 minutes; and (4) in the above (2) and (3), a rotational speed of a measurement paddle of the RVA is set to 960 rpm for 10 seconds after the start of the viscosity measurement and is then set to 160 rpm 10 seconds thereafter.

    Abstract: A corrugated display sign with a former panel secured to a backer panel. The former panel includes a central section opposed by two lateral sections, two support members partially cut away from the central section and maintaining a connection with the central section via at least one fold line, and two or more preformed slots, with one slot positioned adjacent to the support members. The display sign further includes a graphic panel operable to be wrapped around exterior edges of the lateral sections, and having ends secured to the backer panel. The display sign is capable of being erected from a knockdown configuration to an erected configuration by folding the lateral sections away from the central section and wrapping the graphic panel about the lateral sections.

    Abstract: A method of folding a flat sheet of material into a decorative symmetrical object includes placing a sheet of flexible material such as paper between a male die member and a female die member and compressing the sheet. This will form crease lines in the sheet and partially fold the sheet. Completion of the folding to form the decorative symmetrical object is accomplished manually.

    Abstract: A Unitary Mold-Press Structure comprising a bottom portion, a top portion, and a hinge is utilized to make disposable plates, pans, and stove burner protectors and liners in one simple manual step from aluminum foil. The bottom portion further comprises an aluminum foil source, a mold member, a cutting structure, folding flaps, and a side cutting member. The top portion comprises a handle structure, a side cutter, and a mold member. The hinge allows for rotation of the top portion relative to the bottom portion. The bottom cutting structure includes a cylindrical holder, a cylindrical spring, and first and second cylindrical steel cutters. The top handle structure includes a cylindrical holder, a cylindrical spring, and first and second annular members. The top handle structure and the bottom cutting structure interact to effect the internal cutting function of the aluminum foil.

    Abstract: A method for manufacturing a wastepaper shock absorbing material using a vacuum forming principle is provided. The method includes disintegrating wastepaper selected from at least one of old corrugated containers, old newspapers and milk cartons, diluting the disintegrated wastepaper to form a pulp suspension, mixing the pulp suspension with a cationic starch to form a mixture, and vacuuming the mixture by applying a first vacuum in a first direction and a second vacuum in a second direction in a vacuum former to vacuum-dehydrate the mixture and provide a shock absorbing material. The first direction is substantially opposite to the second direction. The method further includes drying the shock absorbing material and performing a surface sizing process on a surface of the shock absorbing material. The wastepaper shock absorbing material has a low elastic modulus and density and can be manufactured without using the conventional press process performed by a press plate.
