Description

The present invention relates to a method and an apparatus for extruding continuously molded bodies, wherein an extrusion solution, in particular an extrusion solution containing water, cellulose and a tertiary amine oxide, is extruded through an extrusion orifice into a continuously molded body and is then deflected by means of a deflector (7). To improve the quality of the continuously molded bodies produced by the method or apparatus of the invention, the extrusion orifices are arranged in a row such that the individual, continuously molded bodies exit in the form of a curtain (3) form the extrusion head. This curtain is then deflected by the deflector.

Procédé et dispositif d'extrusion de corps moulés continus. Une solution d'extrusion, contenant en particulier de l'eau, de la cellulose et un oxyde d'amine tertiaire, est extrudée par une ouverture d'extrusion afin d'obtenir un corps moulé continu, puis déviée à l'aide d'un dispositif de déviation (7). Pour améliorer la qualité des corps moulés fabriqués selon ledit procédé ou à l'aide du dispositif selon la présente invention, les ouvertures d'extrusion sont placées en rangée de manière telle que les corps moulés individuels sortent de la tête d'extrusion sous forme de rideau (3). Ce rideau est alors dévié par le dispositif de déviation.
