  • the opposing arrangement of two suction pipes achieves a very precise distribution of tobacco depending on the amount of suction air on both pipes, which allows a uniform feed of one or two machines. If both pipes are sucked at the same air velocity, an exact 50/50 mass flow distribution of the tobacco takes place. If a pipe is sucking at a lower air velocity, the tobacco is divided according to the flow conditions.
