Abstract: A method for manufacturing a vesicant cup includes a cut fan-shape vesicant plate having thinner upper and lower arcs formed as upper and lower edges. The vesicant plate is rolled and pressed on two stacking joints formed on left and right edges of the vesicant plate respectively. The pressed joints are thinner than other portions of the cup body not being pressed. A lip is formed by rolling up the upper edge outward, and a bottom join is formed by folding up the lower edge inwards. An edge of a vesicant cup bottom is bent downwards as a round joint for connecting and sealing the bottom joint of the vesicant cup body. A thickness of the round joint, bottom joint and the vesicant cup body corresponding to the round joint is thinner than other portions of the vesicant cup body not being pressed.

Abstract: Tearing, blistering, delamination and other defects in deep drawn plastic laminated paperboard containers are eliminated by adding controlled amounts of warmed moisture to the paperboard immediately prior to forming thereof. Water is heated to a desired temperature and is applied by in-line processing equipment to the unlaminated side of the paperboard which functions to both soften and paperboard and preheat the laminate. By heating both the male and female parts of a die press employed for forming the preheated, softened laminate into the container, preheating the laminate using warm water prior to forming and, continuously controlling the moisture added to the paperboard, the degree of stress imposed on the plastic layer of the laminate and the resulting defects in the formed container are significantly reduced.

Abstract: Apparatus and method are provided for producing paper products by forming a paper sheet stock into a desired shape, forcing the shaped paper product through a heat-setting tube, and steam heating the shaped paper product sufficiently to maintain its shape upon removal from the heat-setting tube. Maintaining the paper product in its desired shape is accomplished by supplying steam into the interior of the heat-setting tube and into a steam tube surrounding the heat-setting tube. Preferably, superheated steam is employed in the formation of a nested group of shaped paper products, such as coffee filters, which are simultaneously produced from multi-layered paper sheet stock.

Abstract: Structures including a curved corrugated wall fabricated from a plurality of layers formed of one or more shaped strips and methods of forming the structures are described. A shaped strip used in the fabrication includes a variable profile across the width of the strip with a first edge of a strip defining a series of cell profiles of a first geometric shape and a second, opposite edge of the strip defining a series of cell profiles of a second, different geometric shape, with each cell transitioning from the first profile to the second profile across the width of the strip. The geometry of the cell profiles at either end of each cell can be designed with respect to one another to allow for radial orientation of the strip about an axis with little or no deformation or stress on the strip edges.

Abstract: A method for manufacturing three-dimensional products with at least one inclined product portion made of a fiber-containing material using at least one forming tool and a forming tool are described. Vibrations are introduced via a device and this results in an improved compression of fiber-containing material in the region of inclined portions.

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.
