Abstract: An apparatus for manufacturing cigarette dual filter plugs according to this invention comprises a first grooved convey drum for receiving a filter rod of a first type from a first hopper and conveying the filter rod, a cutting wheel for cutting the filter rod into halves during conveyence thereof by the first convey drum, and a separation guide for separating the cut rod halves so as to leave a predetermined space therebetween. The apparatus also includes a second grooved convey drum for receiving the rod halves from the first convey drum and a filter rod of a second type from a second hopper between two rod halves, and a plurality or cutting wheels are arranged near the second convey drum to cut the two rod halves and the filter rod of the second type into equal numbers of chips, to form two groups of filter chips of the first type and one group of filter chips of the second type.

Abstract: A shredded tobacco supplying device for a cigarette making machine is disclosed, including a tank to receive shredded tobacco, a conveyor for unloading the shredded tobacco out of the tank, a high speed impeller positioned to scatter the unloaded shredded tobacco toward a vertical chimney arranged above the path of the scattered tobacco and connected to a negative pressure source to draw the lighter weight pieces through the chimney, a channel vertically arranged below the scattered tobacco to allow the heavier pieces to drop, and a mechanism for receiving and crushing the heavier pieces into smaller pieces and for supplying the crushed smaller pieces back to the impeller.
