<p>A vented filter cigarette comprises a filter (14) having a fiber filter material (20) and a plug wrap paper (18) wrapping the fiber filter material, a tobacco rod (12), and tipping paper (16) having a plurality of pores (22) and connecting the filter and the tobacco rod. An embossment (24) is formed in a region of the plug wrap paper (18) corresponding to the pores (22) of the tipping paper (16). The embossment (24) creates a slight gap between the tipping paper (16) and the circumference of the filter (14) around the pores (22), with the result that the tightness between the tipping paper (16) and the circumference of the filter (14) is loosened, the filter ventilation is increased, and the variation in the filter ventilation is decreased. <IMAGE></p> |
