发明名称 Spinning device and method having cooling by blowing.
摘要 The present invention relates to an apparatus for producing continuously molded bodies from a molding material, such as a spinning solution containing cellulose, water and tertiary amine oxide. The apparatus ( 1 ) comprises a die plate ( 3 ) including extrusion orifices ( 4 ) through which the molding material is extruded into substantially filament-like continuously molded bodies ( 5 ). The continuously molded bodies ( 5 ) are passed through an air gap ( 6 ) and guided in a precipitation bath ( 9 ) by a deflector ( 10 ) to a bundling means ( 12 ) where they are united into a bundle of fibers. In the air gap, a blowing means ( 14 ) is provided for directing a cooling gas stream ( 15 ) onto the continuously molded bodies ( 5 ) in a direction transverse to the direction of passage ( 7 ). To improve the spinning stability and mechanical properties of the continuously molded bodies, it is intended according to the invention that directly with respect to the extrusion orifices ( 4 ) a first shielding zone ( 20 ) is arranged by which the extrusion orifices are shielded against the action of the cooling gas stream.
