Abstract
A cigarette making machine comprises means for feeding tobacco towards a part of the machine which forms the tobacco into a tobacco stream, a trimmer arranged to trim away part of the tobacco stream, and means for feeding the discard tobacco (i.e., the tobacco removed from the stream by the trimmer) back to the tobacco-stream-forming part of the machine. The trimmer is arranged so that it can remove a temporarily increased amount of tobacco while the machine is being started. In particular, the tobacco stream is formed by showering tobacco towards a conveyor on which the tobacco builds up into a tobacco stream; and the discard tobacco is showered towards the conveyor at a position such that it forms part of the tobacco stream which is not removed by the trimmer. The tobacco may be showered upwards with the aid of an air stream towards the conveyor.
