    Abstract: The invention relates to a method and a device for dispersing fibrous material. The fibrous material is accelerated and expanded together with a flowing medium in a nozzle (10). The nozzle (10) includes a converging and a diverging section and, thus, is a so-called de Lavel nozzle.

    Abstract: Fibre material is defibrated and dispersed in an air flow and introduced through an inlet (2) into a forming head (1). In the forming head (1) the inlet transforms to a single-curved convex surface (5), which leads all the way to an accept outlet (6). A screen (7) is located at adjustable distance from the curved surface (5) for dividing ingoing fibre/air flow into accept and reject. An outlet (10) for the reject is located behind the screen (7). At a distance of 10-150 mm from the accept outlet (6) a running air-pervious support (27) is located, on which the web precipitates.

    Abstract: Soft paper from cellulose fibres is manufactured by wet-forming a first fibre layer. Thereafter air-borne dry fibres are deposited directly on one or both sides of the wet-formed layer while this is still wet, so that a second and possibly a third fibre layer are formed on the first one. Fibre bindings thereby arise between the layers. The wet-formed fibre layer gives the soft paper its strength, while the dry-formed fibers give a soft surface.

    Abstract: A process for the manufacture of porous cellulose particles, which have regular shape, and a capacity of sorbing 1.5-9 times of their own weight of water, a tap bulk density of less than 0.85 g/ml is provided. The process for the manufacture of these porous cellulose matrices is performed by mechanically treating of hydrolyzed cellulose in a wet stage. The cellulose matrices have preferably a size of at least 0.1 mm and a tap bulk density of 0.1-0.7 g/ml. A bioactive substance or bioactive substances could be sorbed, precipitated or sublimized into the porous structure of the matrices. The matrices can be admixed with drugs or drug containing granules in order to improve the tabletting and tablet properties and thereafter compressed.Drug loaded matrices can be used for direct compression of tablets.
