ABSTRACT:
A tobacco stream which is formed at the upper side of one elongated reach of a foraminous endless belt conveyor opposite a suction chamber is inverted upside down by a twisted intermediate portion of the elongated reach so that it adheres to the underside of such reach by suction before it is transferred onto a web of cigarette paper. The elongated reach of the foraminous conveyor is guided in the groove of an elongated channel which has a flat surface upstream, a twisted surface adjacent to and a flat surface downstream of the intermediate portion of the elongated reach, and such surfaces are formed with suction ports to attract the tobacco stream to the elongated reach.
