Abstract
Procedimiento para mantener limpias las placas de agujeros y toberas en la extrusión de polímeros conformables a partir de fusión, especialmente para evitar las sedimentaciones en las proximidades de las desembocaduras de las toberas por gasificación de estas aberturas de las toberas en la salida de la fusión, caracterizado porque el gas se compone total o parcialmente de vapores de aquellas sustancias que ejercen un proceso disociador sobre las sedimentaciones en el borde las toberas que provienen de la fusión.
