Abstract

Unità di alimentazione (1) per una macchina confezionatrice di sigarette, in cui del tabacco trinciato (3) viene alimentato verso un nastro convogliatore aspirante (4) attraverso un canale di caduta (9) ed un canale di risalita (14), alla cui econfluenza è disposto un pozzetto di caduta (15) delle particelle pesanti contenute nel tabacco; un condotto d'ingresso (22) convoglia queste particelle entro un dispositivo separatore a ciclone (23), in controcorrente ad un flusso d'aria ascendente prodotto da un ugello (28), che definisce all'internodel dispositivo un condotto anulare (29) di sezione variabile in cui le particelle pesanti vengono separate in tabacco e coste; le coste sono scartate ed il tabacco viene alimentato verso il canale di cadute (9) e/o il canale di risalita (14). (figura 2).
