ABSTRACT:
In apparatus for feeding tobacco to cigarette-making machines, the tobacco (9) is conveyed by suction from a feed receptacle (1). One end (14) of a duct (3) facing the receptacle above the level (19) of the tobacco is provided with a device (16) for regulating the rate of tobacco delivery in order to allow continuous feeding of the cigarette-making machine. The regulating device comprises a movable sleeve (17) slidable on the end portion (14) of the duct so that the bottom rim (18) of the sleeve is always at a required distance H from the level of the tobacco, this distance being continuously detected by a sensor (25), and the quantity of tobacco drawn into the duct to be adapted to the rate of production being a function of H. The other end (15) of the duct opens out into a tangential separator (12). The regulating device combined with the tangential separator makes it possible to reduce damage to the particles of tobacco.
