ABSTRACT:
A receiving apparatus for a filter cigarette making machine comprises a rotatable catcher drum (2). The drum (2) has receiving grooves (6) in its outer circumferential surface, for each receiving a cigarette rod (CR). A rod (CR) received in the groove (6) moves forward into a braking area therein. In the braking area, the rod (CR) receives braking force due to suction and is stopped. A pair of limit sensors (40, 42) are arranged outside the drum (2). The sensors (40,42) optically detect a rear end of the rod (CR), and on the basis of the result of this detection, whether a stop position at which the rod is stopped is within a tolerance area or not is determined. On the basis of the result of this determination, a controller (38) regulates the braking force exerted on rods (CR) to thereby control the stop position of the rods (CR). Then, a pusher (26) pushes the rod (CR) from its stop position back to a normal position, in each of the grooves (6).
