Abstract
Smaller and larger fragments of tobacco ribs are sifted out of a mixture of tobacco ribs and tobacco shreds before the shreds are converted into a rod-like filler which is ready to be draped into a web of cigarette paper. The larger ribs are comminuted and are mixed with smaller ribs prior to readmission into the flow of shreds in such a way that the readmitted ribs are located in the inner portion of the rod-like filler so that they are less likely to puncture the wrapper and that they contribute to hardness of the filler.
