Abstract: The invention relates to a method for manufacturing a disposable board drinking cup ( 10 ) and to the cup produced by the method. The cup is manufactured by folding a board blank between the cup mantle ( 5 ) and the collar ( 6 ), by bending and seaming the folded blank into a cone, the folding point forming the cup mouth ( 8 ), and by providing the thus seamed blank with a bottom. The cup thus formed comprises both a mantle ( 5 ) and a collar ( 6 ) bent downwardly from the cup mouth ( 8 ) and acting as a grip surface, making it easier to enjoy especially a hot drink from the cup. The shape of the cup mantle ( 5 ) and the collar ( 6 ) may be conically expanding, allowing the cups to be nested. The lower edge of the collar ( 6 ) can be equipped with a projection ( 12 ) for maintaining an air slot between the collar and the cup mantle.

Abstract: The invention relates to a method and an apparatus for drying a moving web of material at a paper or board machine. The drying is performed by a heated drying cylinder (1) transverse to the direction of travel of the web, past which the web is being led. According to the invention, the drying cylinder (1) has been constructed so that its temperature can be adjusted independently at different locations in the longitudinal direction of the cylinder, i.e. the transverse direction of the web. With the adjustability of the drying cylinder it is possible to eliminate moisture differences occurring in the transverse direction of the web in connection with the drying. Especially, it is possible to eliminate moisture lines in the longitudinal direction of the web, which are generated when forming the web on the wire. The drying can be done by independently adjustable resistance wires (12) arranged at different locations of the cylinder, by heating vapour supplied independently to different zones of the cylinder, or by using both drying methods simultaneously in the same drying cylinder.

Abstract: A method and equipment for molding an article produced from paperboard or cardboard. Moulding is carried out by a molding tool that mechanically works the board; and to improve its moldability, momentary irradiation on the microwave frequency is exerted on the board. The method applies to the manufacture of packages and disposable containers made of paperboard or cardboard; for example, to the forming of a rolled-up or folded rim around a drinking cup, mug or a container, the forming of a stiffening crease or projection on a paperboard container, or to press molding of paperboard containers or plates.

Abstract: The invention relates to a method for forming a mouth roll (2) to a cup (1) made of plastic-coated board and to the cup provided with a mouth roll produced by the method. The mouth roll for stiffening the cup is produced with a suitable striking tool bending the board at the mouth of the cup. In accordance with the invention, the mouth roll is additionally stabilized by melting the plastic coating (8) of the board under heat so that the opposite surfaces of the board adhere to each other by heat-sealing in the area of the roll. Melting can be performed e.g. by hot-air blasting directed to the mouth roll at is production stage.

Abstract: The invention relates to a method for digitally printing a polymer-coated paper or board (1), to a paper or board suitable for the method and to the production of a product package equipped with digital prints. During digital printing, printing ink particles are applied in an electric field to the printing surface formed of a polymer coating at locations corresponding to the print, and the printing ink is adhered to the printing surface by fusion with the aid of infrared radiation. In accordance with the invention, the paper or board (2) to be printed is equipped with an inner coating layer (3) containing electrically chargeable ethene acrylate copolymer, such as ethene methyl acrylate copolymer (EMA), and with a polyolefin-based outer shield layer (4) on top of this, which contains e.g. low-density polyethene (LDPE) and provides mechanical strength, forming the printing surface receiving the printing ink.

Abstract: The invention relates to a digital printing method and a paper or board applicable thereto. In digital printing, the surface of a paper or board is charged electrically, toner particles are brought to the surface in an electric field in accordance with the printing, and the particles are melted fast to the surface with the help of heat for forming the printing. According to the invention, the paper or board (2) is provided with a coating layer (3) containing an electrically chargeable acrylate copolymer of ethylene, which receives the toner that is fused to the coating with the help of infrared radiation. Suitable coating polymers are especially methyl, ethyl and butyl acrylate copolymers of ethylene (EMA, EEA and EBA). Especially in packaging boards, besides the digitally printable layer, the polymer coatings can comprise a water vapor or oxygen barrier layer for protecting the packed product, and a heat-sealable layer on the opposite side of the board for sealing the package.
