Abstract: A 3D shaped product (20) is formed by hot pressing of an air-laid blank (10) comprising natural fibers at a concentration of at least 70% by weight of the air-laid blank and a thermoplastic polymer binder at a concentration selected within an interval of from 2.5 up to 30% by weight of the air-laid blank. The 3D shaped product (20) is recyclable in a repulping process. At least a part of the thermoplastic polymer binder is water soluble at a repulping temperature of the repulping process. The 3D shaped product (20) are environmentally friendly alternatives to plastic 3D shaped products made by foamed polymers and can be recycled in existing recycling schemes.

Abstract: Disclosed is a process of manufacturing a thickened angle ring. The process includes the steps of: soaking wet paper into deionized water for 1 hour; beating bonding surfaces of the two pieces of wet paper into fuzzed and rough surfaces; placing a heat resisting polyester film and a nylon net on a mold, and placing one fuzzed wet paper on the mold in contact with the nylon net on smooth side thereof; placing the other wet paper in contact with the fuzzed surface of the previous wet paper on fuzzed side thereof, and beating until the wet paper fits the mold; placing a further heat resisting polyester film and a further nylon net on the two pieces of wet paper for pressing.

Abstract: Systems and methods for producing pressware are provided. In one or more embodiments, a method for producing pressware can include producing a pressware product between an upper forming die and a lower forming die contained within a forming die assembly, retracting at least a portion of the upper forming die from the pressware product, and ejecting the pressware product from the lower forming die while feeding a web material between the upper forming die and the lower forming die. The method can also include cutting a segment of the web material to produce a substrate, and pressing the substrate between the upper forming die and the lower forming die to produce another pressware product.

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: In one embodiment, an apparatus and a method of manufacturing a paperboard tray therewith is provided. In particular, a hub is configured to rotate about a shaft. On the hub, a plurality of first molds are formed in the hub. Conversely, a plurality of second molds are each disposed above each of the plurality of first molds respectively and rotate above the first molds. In this configuration, the plurality of second molds are configured to move in unison with the plurality of first molds as the hub and second molds rotate and to move orthogonally towards and then away from the first molds as the second molds rotate.

Abstract: This invention concerns a press and a method in particular for the forming of finished articles, such as containers or trays of paper and starting from a moisturized sheet. The press comprises a bedplate (18) having a fixed die holder plane (19) holding a head (20) with a moving die-holder plane (21) movable with regards to the fixed plane between an opening and a closing position. A lower die (22) is attached to the fixed die holder plane, whereas an upper die (23) is attached to the moving die-holder plane. The moving die-holder plane is powered by an electric actuator (29) for the opening and closing movements and the half-dies are provided with heating means for the drying and hardening of the paper in a set closed position. The moving die-holder plane can be slowed down or stopped during its stroke to allow for the drying of the paper.
