ABSTRACT:
Oval filter cigarettes are made by forming rod groups each comprising at least one cigarette portion and at least one filter portion in axial alignment; placing each rod group on a wrapping member rotatably carried by a conveyor having a succession of such wrapping members, each group being provided with a portion of uniting paper overlapping the members of the group; and rotating each wrapping member with respect to the conveyor about an axis parallel to that of the rods so as to wrap the uniting paper of least partly around the corresponding rod group.
During rotation of each wrapping member the uniting paper may be gripped by suction ports to provide a tight wrap.
