Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA A PRODUçãO DE CORPOS MOLDADOS CELULóSICOS"<D>. A invenção refere-se a um processo para a produção de um tecido colocado torcido contendo fibras celulósicas torcidas com solvente. O processo é caracterizado pelo fato de que uma solução de celulose em um óxido de amina terciária aquosa é extrudada através de uma fiandeira (1) com orifícios e os filamentos extrudados (3) são esticados em um vão de ar e levados para um banho de precipitação (2), os filamentos no banho de precipitação (2) são interceptados por um primeiro dispositivo transportador (5), por meio do qual uma cortina de fios de filamentos basicamente orientados paralelos um ao outro e basicamente de espessura constante é formada no primeiro dispositivo transportador (5), a cortina de fios é transportada por meio do primeiro dispositivo transportador (5) para fora do banho de precipitação (2) sobre um segundo dispositivo transportador (8) inclinado descendente e a cortina de fios é transportada para baixo no segundo dispositivo transportador (8) sobre um terceiro dispositivo transportador (10) onde o terceiro dispositivo transportador (10) puxa a cortina de fios em uma velocidade menor do que a velocidade da cortina de fios transportada para baixo no segundo dispositivo transportador.
