Title: IMPROVED APPARATUS FOR COMBINING FILTER COMPONENTS
Abstract:
An apparatus for handling filter rod segments for smoking articles comprises a rotating drum having flutes on a peripheral surface of the drum, the flutes for receiving filter rod segments as the drum rotates and for conveying the filter rod segments to an output station; and a transfer assembly for receiving at least a filter rod segment at the output station and for advancing the filter rod segments from the output station in a first conveyance direction extending parallel to an axial direction of the drum. A transverse cross section of the flutes is substantially cup-shaped and symmetrical with respect to a radial drum direction defining a plane (X) of substantial symmetry of the flute. A receiving surface of each flute contacts the outer surface of the at least one filter rod segment at least at two points separated by at least about 150degrees about the periphery of the at least one filter rod segment.
