Apparatus for manufacturing dual filter plugs for cigarettes and method of manufacturing the same.

摘要

An apparatus for manufacturing cigarette dual filter plugs according to this invention comprises a first grooved convey drum (24) for receiving a filter rod (Fc) of a first type from a first hopper (12c) and conveying the filter rod (Fc), a cutting wheel (30) for cutting the filter rod (Fc) into halves (Fh) during conveyance thereof by the first convey drum, and a separation guide (36) for separating the cut rod halves (Fh) so as to leave a predetermined space therebetween. The apparatus also includes a second grooved convey drum (38) for receiving the rod halves (Fh) from the first convey drum (24) and a filter rod (Fp) of a second type from a second hopper (12p) between two rod halves (Fh), and a plurality of cutting wheels (46) are arranged near the second convey drum (38) to cut the two rod halves (Fh) 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 of second type. The filter chips of the respective groups are then transferred from the second convey drum (38) to a staggering drum (48), the filter chips of each group being staggered in the convey direction.
