An apparatus (1) for automatic wrapping of a wrapping blank (3) on lateral walls of a cardboard box (2), the wrapping blank (3) having a base (301) and a plurality of flaps (302, 303, 304, 305) connected thereto, comprises a plurality of folding heads (5) for folding the flaps of the wrapping blank (3) and tucking in their outer portions. Each folding head (5) includes a pair of fingers (502A), positionable inside the box (2) and movable reciprocally towards and away from each other so that the fingers (502A) can be reciprocally moved in sliding contact with the wrapping blank (3) on the internal surface of the lateral wall of the box (2).

A method for producing a cellulose product from a multi-layer cellulose blank structure, wherein the method comprises the steps; forming the multi-layer cellulose blank structure from at least a first layer of dry-formed cellulose fibres and a second layer of a cellulose fibre web structure, through arranging the at least first layer and second layer in a superimposed relationship to each other and in the superimposed relationship arranging the at least first layer and second layer in contact with each other; arranging the multi-layer cellulose blank structure in a forming mould; heating the multi-layer cellulose blank structure to a forming temperature in the range of 100 C. to 300 C., and forming the cellulose product from the multi-layer cellulose blank structure in the forming mould, by pressing the heated multi-layer cellulose blank structure with an isostatic forming pressure of at least 1 MPa, preferably 4-20 MPa, wherein the multi-layer cellulose blank structure is shaped into a two-dimensional or three-dimensional fibre composite structure having a single-layer configuration.

A cutting tool structure, a manufacturing apparatus thereof, and a laminated structure for making a heat-retaining container are proposed. The cutting tool includes: a body; a blade portion extending in a lengthwise direction from the body; and a suppressing portion provided on one side of the body where the blade portion is formed for suppressing the foamed material. The cutting tool structure allows lamination of a foamed sheet and a paper substrate while forming a tear line on the foamed sheet to simplify the manufacturing process of the laminated structure for making a heat-retaining container.

A method of producing a gable-top paper or paper-board based packaging container is disclosed, the packaging container having a plurality of top-closure sub-panels, including a top-closure sub-panel (132) configured to form a pouring spout of the packaging container when the packaging container is in an open position, the top-closure sub-panel being configured to form a pouring spout comprising top-fin panel sections (182a, 182b) being at least partially hot-sealed to each other prior to a first opening of the packaging container, the top-fin panel sections abutting one another in a contact region when the packaging container is in a closed position. The method comprises the steps of: producing a blank (100) from a laminate packaging material having an outside heat sealable layer; and treating the outside heat sealable layer in a sub-region (192a, 192b) of at least one of said top-fin panel sections (182a, 182b) reducing or eliminating the heat-sealing capacity of the outside heat sealable layer in the sub-region. A related blank and a packaging container produced from such a blank is also disclosed.

A method for fitting a paper sheet includes a water absorption step of causing a region of the paper sheet to absorb water, the region being at least a part of the paper sheet; a placing step of placing the region of the paper sheet between one set of first molding surfaces of a press mold; a molding step of molding the region of the paper sheet into a three-dimensional shape, by closing the press mold; a layering step of layering another paper sheet that is not caused to absorb water on the molded paper sheet, after opening the press mold; a fitting step of fitting the molded paper sheet and the another paper sheet by closing the press mold to mold a laminate into a three-dimensional shape; and a removal step of removing a molded article including a fitting portion, after opening the press mold.

A method for fabricating a bubbler is disclosed, which is performed by laminating a polypropylene (PP), PE, CPET film onto a paper material surface to form a PP, PE, CPET film, and then screen printing or coating a hydrophilic polyurethane (PU) material onto another surface of the paper material to form a hydrophilic PU foaming material, then color printing a print material onto the hydrophilic foaming film to form a pattern layer, trimming the paper material to form a paper plate having a desired range, and forming the paper plate as an utensil, and enabling the hydrophilic PU foaming film to form a three dimensional pattern area on a surface of the utensil by being heated and thus foaming with a heating temperature presenting when the utensil is formed, whereby a three dimensional pattern area may be directly formed onto a surface of a utensil.

Various embodiments of the apparatus and methods are configured to make containers such as disposable reinforced cups using reinforcing members configured to be respectively attached to cups. The apparatus and method of various embodiments of the present disclosure sequentially heat different or selective portions of the heat activated adhesive on the reinforcing member at multiple sequential stages, steps or times to attach the reinforcing member to the container.

A method for wrapping a cardboard box with a wrapping sheet, includes: providing a cardboard box with a continuous edge delimiting an opening of the box; providing a wrapping sheet; coupling the box and the sheet; placing on a supporting surface the box coupled to the sheet so that the opening of the box is opposed to the supporting surface; positioning a closing system on the continuous edge of the box so as to define a closed chamber that is comprised between the box and the closing system; supplying air inside the closed chamber so as to make the box adhere to the sheet.
