Abstract

Questa invenzione si riferisce ad un'apparecchiatura per l'estrusione in continuo di un materiale viscoso avente fibre di rinforzo discontinue al suo interno. L'apparecchiatura ha un gruppo di testa di estrusione rotante che include una matrice di estrusione avente un passaggio di estrusione. Una moltitudine di vani si estende al di fuori dal passaggio di estrusione. In risposta alla rotazione del gruppo di testa di estrusione le fibre vengono orientate su di un elica intorno al mandrino.
