Abstract

L'invention concerne une extrudeuse comprenant un orifice d'évacuation sous la forme d'une filière d'extrusion (3) et un deuxième orifice d'évacuation (4) situé en amont de la filière d'extrusion (3). L'invention est caractérisée en ce que le deuxième orifice d'évacuation (4) se présente sous la forme d'un dispositif de régulation de pression pour réguler la pression au niveau de la filière d'extrusion (3). L'invention concerne en outre un procédé de régulation de la pression au niveau d'une filière d'extrusion (3) d'une extrudeuse. L'invention permet l'utilisation de filières d'extrusion optimisées dans des extrudeuses pour des applications à haute pression.
