Abstract

Una testa di estrusione (1) presenta uno stampo maschio (5) alloggiato in un corpo di supporto (2) ed avente un canale centrale (6) percorso in continuo da un semilavorato (7).Uno stampo femmina (9) presenta una sede sagomata (10) definente, con lo stampo maschio (5), un lume di efflusso (11) per la mescola da applicarsi sul semilavorato (7).La sede sagomata (10) è definita in un elemento centratore (12) alloggiato girevolmente secondo un asse obliquo ed incidente rispetto all'asse del canale centrale (6), in un collare intermedio (13) girevole nel corpo di supporto (7) coassialmente al canale centrale stesso. Ruotando l'elemento centratore (12), il lume di efflusso (11) trasla fra una posizione centrata ed una posizione di massima eccentricità rispetto al canale centrale (6). La rotazione del collare intermedio (13) modifica l'orientamento del piano comune contenente gli assi del lume di efflusso (11) e del canale centrale (6).
