Abstract
The distributor of a cigarette maker has an upright duct with an inlet at the top and an outlet at the bottom. The inlet receives particles of tobacco from a magazine and the accumulated particles descend in the duct to be removed at the outlet by the carding of a rotary drum-shaped conveyor in a substantially horizontal direction. The front wall of the duct, as considered in the direction of removal of tobacco particles from the duct, and the lower portion of the rear wall of the duct are oscillated, out of phase, by a common drive which moves the front wall and the lower portion of the rear wall horizontally at right angles to the direction of advancement of removed particles and in the general plane of the respective wall. The inner side of the front wall has protuberances which oscillate with reference to stationary protuberances at the inner side of the upper portion of the rear wall to promote the distribution of particles across the duct.
