Abstract: A tobacco shredding machine wherein an upright duct delivers particles of tobacco to the rear portion of a channel wherein the particles are converted into a continuous cake whose front end is severed by a set of orbiting knives. The lower rear portion of the duct contains a deflecting conveyor which diverts the oncoming tobacco particles from a vertical path into a horizontal path and drives the oncoming particles at a speed which is a multiple of the speed of tobacco compacting conveyors flanking the channel. The speed of the deflecting conveyor is changed in response to changes in the height of the opening between the stationary and movable sections of a mouthpiece through which the cake passes on its way into the range of the oribiting knives. This ensures that the height of the opening reassumes its normal value without changing the speed of the compacting conveyors. The deflecting conveyor is installed in a support which is removably insertable between the side walls of the duct.
