An image processing device includes: a fold unit that folds a first adjustment sheet including an adjustment pattern, over the adjustment pattern based on a predetermined reference fold position; an image reader that reads an image of the adjustment pattern with the first adjustment sheet folded by the fold unit unfolded; a position identifying unit that, based on a fold line in the image of the adjustment pattern read by the image reader, identifies a position of the fold line; and a position adjusting unit that adjusts a fold position of the fold unit based on a difference between the position of the fold line identified by the position identifying unit and the reference fold position. The image reader includes a scanner that scans the first adjustment sheet relatively in a direction along fold of the first adjustment sheet, and reads the image of the adjustment pattern.

METHODS FOR MAKING PAPER OR BOARD, A BOARD TRAY AND PULP PARTICLES COATED WITH FOAMABLE POLYMER FOR USE IN THE SAME

The invention concerns a method of manufacturing paper or board, the paper or board obtained by the method, and a method of producing a tray from the board. In a fibrous stock for papermaking is incorporated an amount of polymer coated fibrous particles, which even have a foaming agent such as moisture contained therein. A web is formed from the fibrous stock on a forming fabric of a paper or board machine, followed by pressing and drying to a finished paper or board. As the paper or board is sufficiently heated the foaming agent within the particles evaporates, causing expansion and foaming of the polymer coating, which adds to malleability of the board as it is moulded into a shaped article such as a board tray. The invention even covers production of doubly coated fibrous particles for use in said methods, the inner coating layer being of a foamable polymer with a higher melt flow rate and the outer coating layer being of a non-foaming polymer of a lower melt flow rate.

FOLD-ENFORCING ASSEMBLY, POST-PROCESSING APPARATUS, AND IMAGE FORMING SYSTEM

A fold-enforcing assembly includes a fold-enforcing device, a moving device to move the fold-enforcing device in a direction of a fold of a sheet bundle, and control circuitry. The fold-enforcing device includes a pressing member pair to nip and press the fold of the sheet bundle in a direction of thickness, a pressing mechanism to pressurize and depressurize the pressing member pair, and a driver to drive the pressing mechanism. Controlled by the control circuitry, the moving device moves the fold-enforcing device in accordance with a size of the sheet bundle in the direction of the fold; pressing mechanism pressurizes the pressing member pair to press a first end portion of the sheet bundle in the direction of the fold; the moving device moves the fold-enforcing device to a second end portion of the sheet bundle; and pressing mechanism depressurizes the pressing member pair in the second end portion.

Method for three-dimensionally shaping resin packaging member, and resin packaging member

A method for three-dimensionally forming a resin packaging member. The resin packaging member is heated to a temperature not higher than the Vicat softening temperature of the packaging member, and then compression shaping is conducted at a temperature not lower than room temperature and not higher than the Vicat softening temperature so as to form a three-dimensionally shaped portion with a large protrusion.

Pressing roller for the processing of web paper material
10737456 · 2020-08-11 ·

A pressing roller (10) for the processing of web paper material, in particular of the type used in cooperation with an engraving roller (G1) for the bonding of two or more embossed plies of web paper material, comprises a cylindrical pressure surface (11) defined by a plurality of annular resilient pressure bodies (15) of rubber material that have a high surface hardness which allows to avoid the effect of double embossing and at the same time have a high elastic yielding which allows to obtain adequate nip also with relatively low contact pressures.

NAPKIN
20200223170 · 2020-07-16 ·

A method of applying adhesive to a napkin includes spraying first and second adhesive portions on to a first surface of a napkin, and folding the napkin along a fold such that the first and second adhesive portions are brought into engagement with each other, in which the adhesive is of a type that will allow the first and second adhesive portions to separate and allow the napkin to be adhered to an object.

One piece container

A container comprising a first side-panel section separated from a second side-panel section. Each of the first and second side-panel sections includes a side portion fold line extending laterally across the side-panel sections, such that each side-panel section presents two side portions. Furthermore, the container includes a pair of end flaps extending along lateral edges of the first and second side-panel sections and separated from the side-panel sections via primary fold lines, with the end flaps operable to connect the first and second side-panel sections together. The container is configured to be erected from a knockdown configuration by folding together the first side-panel section and the second side-panel section, and extending the first side-panel section and the second side-panel section away from each other such that the container forms a rectangular perimeter.
