Abstract (en)

A unit for forming a strip of tobacco in a cigarette making machine comprises a conveyor belt (6) looped on at least two rollers (4, 5) one of which is motor-driven; the lower branch (11) of the belt (6) is a suction branch and extends above a vertical flue (14) in which an ascending air current moves the tobacco fibres (15) from the bottom upwards in such a way that they gradually accumulate along the lower branch (11) forming a continuous layer of tobacco; the unit (1) also comprises a belt (6) tensioner (31) and at least one damper (43) operating in conjunction with the tensioner (31), so as to continuously and gently adjust the belt (6) tension to an optimum value.
