Abstract
A hopper for a cigarette making machine has two spiked feed rollers and two cooperating high-speed spiked rollers which feed tobacco from tobacco space and onto a spiked drum; this drum feeds the tobacco along part of its path of conveyance and then cooperates with a second drum so as to stretch out lumps in the tobacco while the tobacco is being carried by the second drum. Alternatively the tobacco may be delivered by the spiked rollers onto a ramp; loose particles of tobacco slide all the way down the ramp, whereas lumps of tobacco are picked up by spiked drum which is slightly spaced from the ramp and which returns the lumps to the ramp after they have been opened out.
