Abstract
The distributor of a cigarette rod making machine has an upright duct the upper end of which receives particles of tobacco from a magazine and the lower end of which has an outlet of variable cross-sectional area. The outlet is adjacent to the carding of a drum which withdraws from the duct a continuous layer of particles, and such particles travel toward a transversely extending barrier which is reciprocated in parallelism with the axis of the drum. The barrier has a grooved first surface which engages the exposed side of and homogenizes the layer, and a second surface which faces counter to the direction of movement of the drum and intercepts the surplus of particles whereby the intercepted particles pile up in front of the barrier. The pressure of piled-up particles is monitored by a sensor which causes a mechanical adjusting device to change the cross-sectional area of the outlet so that the area decreases when the pressure of piled-up particles increases, and vice versa.
