Abstract
Procedimiento para la fabricación de láminas planas celulósicas, para lo cual se extruye una disolución de celulosa en un aminóxido terciario acuoso mediante una boquilla de extrusión, que presenta una ranura de extrusión, a cuyo efecto la disolución se moldea en forma de lámina y la disolución extruida se conduce por una rendija de aire a un baño de precipitación, caracterizado porque se emplea una boquilla de extrusión que presenta una ranura de extrusión de una anchura b de valor 220 m = b = 280 m.
