18, Abstract of the Disclosure, Tobacco Feed System for Cigarette Making Machine A system for feeding tobacco pneumatically and continuously to a cigarette making machine includes a fan (34,116 148) which draws air, through the machine via a suction band (48) and via one or more screens (96,98) and also serves to draw air through a duct by which tobacco is conveyed to the hopper (10) of the cigarette making machine from a tobacco sending device (12). The interior of the hopper is at subatmospheric pressure. This system avoids the need for an air lock in the hopper.
