Abstract

Máquina extrusora para la elaboración de material termoplástico que comprende: un cuerpo provisto de un taladro que se extiende longitudinalmente a lo largo de dicho cuerpo, un rotor provisto de por lo menos un fileteado helicoidal a su alrededor, una abertura de alimentación en un extremo de dicho cuerpo para permitir depositar en dicho cuerpo cualquier material a elaborar, cuya abertura de alimentación está en comunicación con el citado taladro, una abertura de descarga en el otro extremo de dicho cuerpo para permitir la extrusión de cualquier material elaborado en el mismo, caracterizada porque dicho rotor (16) está provisto de por lo menos una barrera en general anular (74,76) a su alrededor, cuya barrera está provista por lo menos de un entrante para permitir la circulación del material pasante, cuya máquina de extrusión (10) comprende asimismo un paso de derivación (84) con respecto de la barrera y medios (86) para desplazar axialmente dicho rotor (16) y dicha barrera anular (74,76) con respecto a dicho paso de derivación (84) de la máquina extrusora (10) para permitir una variación en la elaboración efectuada en cualquier material que circule a través de la misma.
