20090133282Method and Apparatus for Drying a Moving Web of Material at a Paper or Board Machine - 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 (05-28-2009
20100112247BOARD, A METHOD OF MANUFACTURING THE SAME AND A CONTAINER MADE FROM IT - The invention relates to a method of manufacturing board (05-06-2010
20100159215DIGITAL PRINTING OF POLYMER-COATED PAPER OR BOARD - The invention relates to a method for digitally printing a polymer-coated paper or board (06-24-2010
20130000858METHOD AND A REACTOR FOR MIXING ONE OR MORE CHEMICALS INTO A PROCESS LIQUID FLOW - A method for mixing a chemical into a process liquid including: injecting the chemical into the process liquid flowing through a flow pipe; forming reaction products by a reaction involving the chemical occurring in the process flow; applying an electric field or magnetic field to a region of the flow pipe adjacent to the reaction occurring in the process flow, and suppressing the precipitation of the chemical or the reaction products on the surfaces of the pipe due to the electric or magnetic field.01-03-2013
20130056383CONTAINER FROM FIBRE BASED BOARD AND A METHOD FOR PRODUCING SUCH A CONTAINER - The present invention relates to a container made from fiber based board wherein the container comprises a sleeve and a bottom, said bottom comprises polymer coated board, at least one side of said sleeve is uncoated and the sleeve is formed by sealing two edges of the sleeve together along a side seam. The invention further relates to a method for producing said container.03-07-2013
20130178650HYDROGEN TREATMENT OF IMPURE TALL OIL FOR THE PRODUCTION OF AROMATIC MONOMERS - A method of manufacturing aromatic hydrocarbons, which are suitable for the production of terephthalic acid, from tall oil-based raw material. According to the invention, the raw material that contains tall oil or its fraction is catalytically deoxygenated with hydrogen, and one or more aromatic hydrocarbons that can be converted into terephthalic acid are separated from the deoxygenated reaction yield. The deoxygenation catalyst is a NiMo catalyst and, in addition, a cracking catalyst can be used, such as an acidic zeolite catalyst. The separated hydrocarbon can be p-xylene, o-xylene or p-cymene. According to the invention, these can be converted by oxidation and, when needed, by a re-arrangement reaction into terephthalic acid that is suitable for the source material of the manufacture of bio-based polyethylene terephthalate.07-11-2013
20130256420CORE WITH A TAG - A paper roll core, which includes a tag and wherein the tag is a tag which is radio-readable and includes a flexible element. The core has its end face provided with a recess with a bottom and a wall, in which the tag is fitted in an at least partially coiled configuration. For example, the tag can be glued in the recess. Alternatively or additionally, the tag can be retained substantially stationary by a springback force evolved as a result of coiling the flexible element, bracing the flexible element against a wall and/or a bottom included in the recess.10-03-2013
20140272213PACKAGING BOARD, ITS USE AND PRODUCTS MADE THEREOF - The invention relates to a packaging board comprising a fibrous base and one or more polymer coating layers on one or both sides of the fibrous base. According to the invention the fibrous base contains the combination of an alkyl ketene dimer size, stearic acid anhydride, a wet-strength size and an aluminium compound, which give the board resistance to aggressive liquids as well as thermal treatment, particularly an improved resistance to raw edge penetration in such circumstances. The invention further relates to containers and packages made of the board, for instance disposable drinking cups, dairy product cartons and auto-clave packages, as well as use of the board for such purposes.09-18-2014
20140345816METHOD OF CONTROLLING RETENTION AND AN INTERMEDIATE PRODUCT USED IN THE METHOD - The invention provides a method of controlling retention on a forming fabric in a paper making process, an intermediate product for use in the method, as well as use of material for the intermediate product. For making the intermediate product at least one paper making chemical is added to a slurry of fine cellulose fibres such as micro fibrillated cellulose (MFC), the specific surface area of those fibres being larger than that of the fibres of the main fibrous suspension for paper making, causing the paper making chemical being adsorbed on the fine cellulose fibres. This intermediate product is then incorporated in the main fibrous suspension before the suspension is supplied from the paper machine head box to the forming fabric. Other paper making chemicals may be added to the fibrous suspension before or after addition of the intermediate product, so that interactions between different chemicals are prevented. The invention permits an increased retention in general as well as improved control of retention of paper making chemicals separately and/or in relation to each other.11-27-2014
20150041529DEEP-DRAWN PAPER TRAY, A METHOD AND AN APPARATUS FOR MAKING IT, AND A TRAY-FORMED PRODUCT PACKAGE - A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.02-12-2015
