Abstract
La invención se refiere a un método para extruir un producto semiterminado hecho de material, elastomérico, caracterizado porque un material elastomérico se alimenta a un canal se alimenta a un canal de entrada (20a) de una bomba de engranajes (20) con un valor de presión de entrada y se dispensa a través de un canal de salida (20b) de la bomba de engranajes (20) con un valor de presión de salida mayor que el valor de presión de entrada. El método consiste en detectar el valor de la presión de salida y ajustar el funcionamiento de dicha bomba de engranajes (20) para mantener una diferencia de presión predeterminada entre dicha presión de salida y dicha presión de entrada en función de la detección del valor de la presión de salida.
