Abstract

L'invention concerne un dispositif d'extrusion pour préparer des matières fibreuses à partir d'une substance polymère et à l'aide d'un fluide de façonnage. Selon l'invention, ce dispositif comporte : a. un tube ou canal d'alimentation appelé à acheminer la substance polymère à extruder, et b. au moins une tuyère du type convergent-divergent dont au moins une partie de la section divergente est insérée dans ledit canal d'alimentation, la section divergente insérée étant divisée en deux parties distinctes par une fente continue appelée à extruder la substance polymère dans ladite section divergente, ladite fente continue étant normale à l'axe principal de la tuyère et communiquant avec ledit canal d'alimentation. Elle se rapporte à un dispositif de préparation de matériaux.The invention relates to an extrusion device for preparing fibrous materials from a polymeric substance and using a shaping fluid. According to the invention, this device comprises: a. a supply tube or channel intended to convey the polymer substance to be extruded, and b. at least one nozzle of the convergent-divergent type of which at least a part of the divergent section is inserted into said supply channel, the inserted divergent section being divided into two distinct parts by a continuous slot called to extrude the polymer substance in said section divergent, said continuous slot being normal to the main axis of the nozzle and communicating with said supply channel. It relates to a device for preparing materials.
