A forming device applied to a cigarette manufacturing machine causes a garniture tape 10 to travel through a wrapping section 8, and meanwhile wraps a shredded tobacco layer T in wrapping paper P to form continuously a cigarette rod R. The tape 10 is guided to travel by a forming guide 18 in the wrapping section 8, and is simultaneously bent to have a cross section of an arc that is downward convex. On the other hand, the travel of the tape 10 is guided by a pair of guide rollers 24 in upstream and downstream sides of the wrapping section 8, and the tape 10 is bent to have a cross section of an arc that is upward convex by guide surfaces of the rollers 24. Thus, difference of travel length, that is generated between both side edges and the central part of the tape 10 in the wrapping section 8, is offset by the guide rollers 24.
