Self-made cigarettes, i.e. tobacco products that are supplied in unsmokable condition in the form of a tobacco-bearing component (12) comprising a tobacco rod (14) attached to a porous filter (16) at least part of the surface of which is highly permeable, and an impervious tubular band (10) carried on the component and slidable along it to cover the permeable region. The tubular band can be applied by compressing the tobacco-bearing component to enable the preformed tubular band to be slid onto it. Tubular bands (10) are automatically assembled onto tobacco bearing components by an apparatus that includes a rotary drum (30) around the periphery of which are distributed sets of assembly tools (62) each of which sets comprises a pair of opposed rods (90, 106) which are employed to Introduce the tubular band and the tobacco bearing component into opposite ends of an assembly cylinder (44) wherein the band is slid onto the tobacco component, the assembled product subsequently being ejected. The components are fed into the successive assembly tool sets as the latter are rotated on the drum past a feed point, actuation of the rods being effected by means of stationary cams (100, 118) past which the rods are moved by rotation of the drum. |
