Abstract

Dispositivo di estrusione (1), una cui testa di estrusione (2) prevede l'utilizzazione di una pluralità di piastre sagomate (9, 10, 11, 12) sovrapposte e bloccate una contro l'altra da un dispositivo di serraggio (3), il quale è disposto, ed agisce, esternamente alla testa di estrusione (2) stessa, attorno alla quale definisce un dispositivo ad anello apribile; il dispositivo di estrusione (1) essendo provvisto di un dispositivo di apertura (4) automatico, il quale consente, quando il dispositivo ad anello (3) è in posizione aperta, di separare le piastre sagomate (9, 10, 11, 12) l'una dall'altra.(FIGURA 2)
