Abstract

La pressa comprende un dispositivo di tenuta e aspirazione (32; 232) montato attorno al punzone (18, 218) con possibilità di scorrere assialmente lungo esso; detto dispositivo, quando il punzone è in funzione entro l'apertura di un contenitore (20) per billette, realizza la tenuta all'aria contro la parete del contenitore.Uno o più tubi di collegamento (42) collegano il vano chiuso con una apparecchiatura generante una depressione o con un ambiente in depressione.Il vuoto viene creato nel contenitore prima di iniziare l'estrusione non appena il punzone è entrato nel contenitore.
