Abstract
A shredded tobacco supplying apparatus for a cigarette manufacturing machine has a supply passage extending toward a conveyor belt, the supply passage is provided with a plurality of air blowing openings arranged at intervals in the direction perpendicular to the longitudinal axis of the conveyor, and a straightening plate having a plurality of straightening fins is mounted at the air blowing opening. The straightening fin extends at a predetermined angle toward the front side of the conveyor with respect-to the axis perpendicular to the longitudinal axis of the conveyor. The air injected from the air blowing opening is blown into the supply passage at a predetermined angle with respect to the aforementioned axis. The shredded tobacco reaching the supply passage is discharged toward the belt surface of conveyor belt by using an air flow produced by the air blown from the air blowing openings. As a result, a velocity component in the belt running direction is given to the shredded tobacco, so that the attracting property of shredded tobacco to the belt surface is enhanced. Thereupon, the reduction in attracting property caused by the increase in belt running speed, and in turn, the …
