Patent ID: 8118033

Claim:
An apparatus for manufacturing rod-shaped smoking articles, comprising: a forming section including a forming path, for forming a material layer made up of particles of smoking material on the forming path, and delivering the material layer along the forming path, said forming section further including a pair of guide members disposed in the terminal end portion thereof, for guiding both sides of the material layer; a wrapping section including a wrapping path, for receiving the material layer from the forming path of said forming section, forming a rod in which the material layer is continuously wrapped in a web in the process where the material layer travels along the wrapping path, and delivering the formed rod, wherein the rod has a lap portion formed by bonding both side edges of the web together in a state where the side edges are superposed upon each other said wrapping section further including: a compression member disposed above the web in the start end portion of the wrapping path, for compressing the material layer from above, and a web shield located between an upstream end portion of the compression member and the web in the start end portion of the wrapping path, for separating the material layer and the web from each other the web shield and the compression member overlapping with each other as viewed in a vertical direction, wherein at least two among the guide member, the upstream end portion of the compression member and the web shield have respective injection openings, a cutting section for cutting the rod delivered from said wrapping section into rod-shaped smoking articles having given length; and an addition device for adding a liquid additive to the material layer by injecting the additive from the injection openings into the material layer wherein the injection openings are spaced from each other in a traveling direction of the material layer and also in a circumferential direction of the material layer.
