Abstract

Patente de Invenção:<B>BOCAL DE FIAçãO"<D>. Um bocal de fiação para a fiação é particularmente apropriado para a fiação de soluções de celulose e tem um corpo de bocal de fiação (1) configurado essencialmente com simetria de rotação, com uma tomada (2) em seu centro para gás de resfriamento, um atomada (3) para soluções de celulose, e um inserto de fiação (4) anular, repuxado em profundidade, feito de metal nobre, com furos de fiação (6). O inserto de fiação tem uma seção transversal em forma de tina. Um prato de choque (5) guia a corrente de gás de resfriamento sobre filamentos de celulose (7), os quais são extrudados através dos furos de fiação (6), de modo que a corrente de gás de resfriamento incide essencialmente perpendicularmente sobre os filamentos de celulose (7) extrudados. Os furos de fiação (6) são uniformemente espaçados um do outro no inserto de fiação (4).
