    Abstract: The invention has for its object a cut-tobacco distributing device for cigarette making machines.The distributing device includes a rotating drum (2) provided with points (3) which takes or receives the cut tobacco.This drum (2) provided with points (3) cooperates with a rotating detaching cylinder (18) which takes the cut tobacco from the said drum (2).According to the invention, in order to reduce the mechanical stresses which exert a degrading action on the cut tobacco, the points (3) of the drum (2) are retractable inside the drum (2) itself and are controlled by cams (8, 9) which retract them, temporarily, in a complete or almost complete way in the region of the detaching cylinder (18).The latter is constructed as a pneumatic suction cylinder without points.
