Abstract

Prensa de extrusión, para el moldeo continuo de mezclas plástico-viscosas de materiales elastómeros o termoplásticos por una cabeza de prensa, que aloja la mezcla a exprimir y una tobera de prensa de extrusión, que cierra esta, cuya sección transversal de paso libre moldeadora es variable, caracterizada porque el volumen de alijamiento de la cabeza de prensa es variable en dependencia de las variaciones de la sección transversal de paso de la tobera de prensa de extrusión.
