A cigarette stacking apparatus is also disclosed.

Cigarette stacking method and apparatus

An apparatus for forming a tab on a tearing tape for a packing film for a pack of cigarettes, etc. and printing an identifying color or pattern on the tab. A cutter is provided on a roller facing a roll for supporting a bonded assembly of a web for forming a plurality of tearing tapes and a web for forming a plurality of packing films. The cutter has a generally U-shaped cutting edge for cutting a tab for each tearing tape. A printing plate is disposed movably in the cutter for printing an identifying color or pattern on each tab simultaneously when it is cut. An inking roller is provided on the opposite side of the cutter from the supporting roll for supplying a printing ink to the printing plate. The printing plate has a printing surface surrounded by the cutting edge and projecting slightly therefrom when the printing plate is in its inoperative position. A spring urges the printing plate to stay in its inoperative position, but allows it to retract to enable the cutting edge to cut each tab, while the printing surface prints an identifying color or pattern thereon simultaneously.
