The tubular portion is made by feeding tobacco shreds against the underside of the horizontal lower reach of a foraminous conveyor belt advancing beneath a suction chamber to accumulate a first layer of shreds. The inserts are delivered to the underside of the first layer and are attracted thereto by suction. A second layer of shredded tobacco is assembled by showering shreds against the underside of the first layer where the second layer underlies the spherical inserts. The thus obtained filler is draped into a web of wrapping material to form a cigarette rod ready to be subdivided into sections of unit or multiple unit length. The spherical inserts are expelled from a revolving receptacle under the action of centrifugal force to form a row which is conveyed toward the underside of and advances with the first layer.

    Abstract: A shredded tobacco feeding apparatus includes an optical sensor (40) for detecting stagnation of shreds in a secondary separator (20). The optical sensor (40) senses the interior of the secondary separator (20) in the width direction thereof, by transmitting and receiving detection light propagated through a stagnation-prone region of the secondary separator which is lower in level than an air locker (18). If the detection light is blocked by stagnant shreds, a controller (58) detects the stagnation based on a detection signal from the optical sensor and operates an alarm device (60). Also, the controller (58) actuates an air vibrator (62) to remove the stagnation of shreds.
