    Abstract: A cigarette making apparatus comprises a filter-plug attachment mechanism arranged to butt a filter plug coaxially against a cigarette and then wrap tip paper around the cigarette and filter plug to cover a joint where the cigarette and the filter plug meet, a laser hole-forming device arranged to form air holes in the tip paper by projecting laser light onto the side of the tip paper intended to contact the cigarette and filter plug (back side), while the tip paper is being supplied to the filter-plug attachment mechanism, and an air-permeability measurement device arranged to measure the air permeability of the tip paper with the air holes formed, wherein the air-flow resistance Vf of a filter-tipped cigarette is adjusted by feedback-controlling the laser hole-forming device on the basis of the air permeability measured.
