ABSTRACT:
A pressure sensor (P) and a time-measurement component actuate a gate (15) for clearing out a duct (7) as a function of a predetermined program. When the gate is open, the feed of the machine is interrrupted. When the gate is closed, suction air carries along tobacco particles from a bed (5), and negative pressure having a critical threshold exists at the level of the sensor. If, when the gate is closed, a plug of tobacco forms in the bottom opening of a sleeve (23), this sleeve is drawn upward by suction and butts against bolts (19), which dislodges the plug of tobacco. If the pressure continues to drop, the gate is opened, the sleeve falls back, and the plug is definitely dispelled.
