Abstract

The carding at the periphery of a driven wheel in the distributor of a cigarette rod making machine receives tobacco particles from the lower portion of a substantially upright duct the upper portion of which can receive tobacco particles from a magazine by way of an elevator conveyor. At least the lower portion of the duct is vibrated (e.g., at an amplitude of approximately 6 mm and at a frequency of 15-25 Hertz) in directions at right angles to the horizontal rotational axis of the wheel to thus enhance the homogeneousness of the carpet of particles being transported by the carding beyond the discharge end of the lower portion of the duct.
