Abstract

UN DISPOSITIVO COLOCADO SOBRE UNA PRENSA DE EXTRUSION PARA LA EVACUACION DE AIRE, QUE CONSISTE EN UN CILINDRO (1) CON UNA MATRIZ MONTADA EN UN EXTREMO, EL DE SALIDA, Y EN UN PISTON (2) DISEÑADO PARA PODER MOVERSE DE UNA POSICION FUERA DEL OTRO EXTREMO, EL DE ENTRADA, A UNA POSICION DENTRO DEL CILINDRO. EN EL LUGAR DE ENTRADA HAY MONTADO UN DISPOSITIVO DE CIERRE INDEPENDIENTE (11) QUE ACOMPAÑA AL PISTON CUANDO SE ENCUENTRA RETRAIDO DEL CILINDRO. EL DISPOSITIVO DE CIERRE CONSISTE EN UNA CARCASA (4) CON UNOS ANILLOS DE CIERRE (8, 9) MONTADOS EN EL PISTON/VASTAGO DEL PISTON (2, 3).
