A tobacco filler is formed in a machine which turns out two trough-shaped tobacco streams whose concave sides face each other. The two streams are thereupon caused to merge and to form a single stream whose central portion is less dense than the outer layer. The single stream is then compacted in the wrapping mechanism of the machine so that its cross section matches that of a cigarette, and the resulting filler is draped into cigarette paper prior to subdivision into discrete cigarettes of desired length. The density of the central portion of the filler in each cigarette is less than the density of the layer which is immediately adjacent to the wrapper. This improves the burning characteristics of the cigarettes and allows for a reduction of the quantity of tobacco which is needed to make a cigarette exhibiting a desired firmness. The single stream can be formed around a mandrel which reduces the likelihood of penetration of tobacco particles into the central portion of the single stream ahead of the wrapping station and which can also serve to admit moisture, volatile flavoring agents and/or heated or unheated air into the adjacent particles of the trough-shaped streams or into the adjacent particles of the single stream.
