ABSTRACT:
A continuous carpet of particulate cigarette filler material, of which part along one side comprises core such as a low quality tobacco or non-tobacco material and the remainder comprises normal tobacco, is rolled by means of an air jet, starting from the core material side of the carpet, to form a cigarette filler stream consisting of an annulus of normal tobacco around a core consisting of the core material. Before the annulus tobacco is rolled around it, the rolled core material is trimmed to remove excess core material. Furthermore, a variable part of the normal tobacco in the carpet is discarded under the control of a sensor responding to the density of the nearly completely formed filler stream.
