Abstract

Macchina per la lavorazione di polimeri termoplastici comprendente una pluralità di elementi coassiali (1a, 1b, 1c, 1d, 1e, 1f), tra loro adiacenti e resi solidali, formanti al loro interno una camera, estendentesi longitudinalmente, all'interno della quale è disposta una coppia di alberi (5, 6) coassiali e interagenti aventi porzioni (5a, 6a; 5b, 6b; 5d, 6d; 5e, 6e) corrispondentemente differenziate per costituire tratti di avanzamento e premescolazione del composto, tra detti tratti essendo interposto un tratto di macchina (1c, 5c, 6c,) costituente un mescolatore interno, formando in tal modo un complesso unitario a elementi coassiali atto a effettuare l'intera lavorazione del composto, a partire dalla materia prima sino alla estrusione, senza discontinuità di ciclo.
