    摘要: A method and apparatus for making patterned paper. A printer (10, 10') patterning the paper is arranged in a patterning unit (4) arranged in a paper machine (1), the printer (10, 10') patterning a paper web (3) being made in the paper machine (1). The printer (10, 10') is preferably an ink-jet printer. The paper web (3) patterned by the patterning unit (4) can be coated by a coating unit (5) arranged in the paper machine (1).

    摘要: The present invention relates to a modified fiber product and a method of producing same. According to the method, the cellulosic raw material is formed into a fiber suspension, into which components modifying the properties of the fibers are added, subsequent to which the fibrous material is dried in connection with, for example, web forming. According to the invention, alkyl derivative of cellulose is mixed into the fiber suspension in alkaline conditions, the derivative being at least partly dissolved in water, and the derivative is allowed to be sorbed into the fibrous material prior to drying such that the sorbed cellulose derivative can not be washed off with water. The strength properties or the water retention of paper and paperboard products can be improved by using the invention.

    摘要: The invention relates to a method of cleaning a moving surface, e.g. a roller, wire or conveyor belt. According to the method, the surface is cleaned by means of a doctor blade comprising several separate blade means (7), which move in a direction transverse to the surface to be cleaned. The invention also relates to an apparatus comprising a doctor blade consisting of several separate blade means (7), which are arranged to move in a direction transverse to the surface to be cleaned so that they can be serviced and repaired during the run.

    摘要: The invention is based on the idea of preparing porous calcium carbonate particles via a degradation reaction from a crystalline initial material which contains the initial components for forming calcium carbonate and additionally initial components for forming the reaction products to be removed from the initial material. In the reaction a substantial portion of the calcium carbonate forms a porous frame in the space occupied by the initial material, around the open space left by the matter leaving the initial material. The invention is also based on the use of such porous calcium carbonate particles as a pigment absorbing printing inks or their solvents on the surface of a printing substrate.
