Cigarette making machines

A cigarette making machine including an upwardly extending chimney and means for delivering tobacco into the lower end of the chimney, the tobacco delivery means being arranged to project the tobacco in a direction transverse to the chimney, from which direction lighter particles of tobacco are deflected upwards into the chimney by an upwardly flowing air stream while heavier particles of tobacco continue past the lower end of the chimney towards a roller which is arranged to project the heavier particles of tobacco downwards at a controlled velocity into a substantially vertical duct through which at least part of the air entering the chimney flows upwards, the projector roller being arranged to project the heavier particles of tobacco along a path inclined inwardly towards the center of the duct and defined by a wall inclined to the vertical, the wall being adjustable so as to vary its angle of inclination to the vertical.

A cigarette making machine including an upwardly extending chimney and means for delivering tobacco into the lower end of the chimney, the tobacco delivery means being arranged to project the tobacco in a first direction transverse to the chimney, from which direction lighter particles of tobacco are deflected upwards into the chimney by an upwardly flowing air stream while heavier particles of tobacco continue past the lower end of the chimney towards a roller which is arranged to project the heavier particles of tobacco downwards at a controlled velocity into a duct through which at least part of the air entering the chimney flows upwards, the projector roller being arranged to continue the motion of the heavier particles of tobacco in substantially the said first direction and at least to maintain the momentum of the tobacco particles.
