Abstract
Procedimiento y aparato para eliminar los compuestos volátiles que escapan de fusiones de plástico en la extrusión de las mismas, caracterizándose el procedimiento porque los compuestos volátiles se aspiran en el momento de salir de la fusión de plástico conjuntamente con el aire ambiente, calentando el aire que contiene los compuestos volátiles en el momento de entrar en la abertura de aspiración.
