Abstract

Una línea de extrusion del tipo con brazo barométrico horizontal y un método de extrusion que incluye una cámara de vacío que en un extremo tiene unamatriz de extrusion, y en el otro extremo un enfriador de inmersion con barrera de agua, paraextraer el material extruido a la atmosfera, equipos parapreparar y formar el material extruido y situado corriente abajo respecto de la matriz, y una pared fija de extremo de diámetro grande en la matriz, ysecciones movibles que rodean los equiposde prepa racion y formacion, y una seccion fija de la cámara que es de tamano menor. La primera seccion establececontacto de cierre con la segunda seccion y la seccion fija, y se mueve sobre la seccion fija, para formar un espacio libre con lasegunda seccion que esmovible dentro de los límites de dicho espacio libre. La seccion fija también establece contacto de cierre con la pared fija de extremo de diámetro grande.De esta manera, los equipos situados corriente abajo pueden serexpuestos de manera comp leta mediante el movimiento de una o ambas de las secciones moviblesy se provee un espacio de trabajo de espacio y volumen adecuados para la produccion en gran escala. Un mecanismo de acoplamiento simplificado facilitalarápida y cierre de la cámara.
