ABSTRACT:
A forming device applied to a cigarette manufacturing machine causes a garniture tape10to travel through a wrapping section8, and meanwhile wraps a shredded tobacco layer T in wrapping paper P to form continuously a cigarette rod R. The tape10is guided to travel by a forming guide18in the wrapping section8, and is simultaneously bent to have a cross section of an arc that is downward convex. On the other hand, the travel of the tape10is guided by a pair of guide rollers24in upstream and downstream sides of the wrapping section8, and the tape10is bent to have a cross section of an arc that is upward convex by guide surfaces of the rollers24. Thus, difference of travel length, that is generated between both side edges and the central part of the tape10in the wrapping section8, is offset by the guide rollers24.
