Abstract
A cigarette rod making machine wherein the surplus of smokable material which is removed by the trimming device is returned into the magazine of the distributor next to the supply of fresh tobacco. Fresh tobacco is withdrawn from the supply in the form of a relatively wide first layer, and the returned surplus is removed in the form of a narrower second layer adjacent one marginal portion of the first layer. The two layers are converted into a stream which advanced toward and past the trimming device in such a way that the latter removes mainly recirculated surplus tobacco which is again admitted into the magazine for conversion into the second layer.
