Abstract
A device for attaching two axially aligned cigarette tobacco columns to an intermediately disposed double length rigid mouthpiece, hereinafter referred to as a cigarette group, by wrapping a sheet of tipping material around the double length rigid mouthpiece and a portion of each tobacco column adjacent to each end of the double length mouthpiece. The device comprises a stationary rolling block located in spaced relationship to the periphery of a cigarette group feed drum. The feed drum carries a plurality of cigarette groups at spaced apart intervals on its' periphery with a sheet of tipping material adhesively attached at the leading edge thereof to each of the cigarette groups. As a cigarette group passes beneath the rolling block, the cigarette group is caused to roll in a counter direction to the rotational direction of the feed drum along the peripheral surface of the feed drum causing the sheet of tipping material to wrap around the double length rigid mouthpiece and portion of each tobacco column immediately adjacent to the double length mouthpiece.
