Method of making cigarettes and a cigarette made according thereto

An improved method of making a smoking article from an endless web of reconstituted tobacco having a mass per unit length substantially equal to that of the smoking article to be made, including the steps of advancing the web along a path of travel, working the web as it travels to modify the structure thereof transversely of its length, forming the worked web as it continues to travel into a continuous rod, applying a wrapping to the rod and cutting the rod into lengths equal to that of the smoking article, the improvement being characterized in that the working is accomplished by longitudinally grooving the web while preventing any substantial transverse contraction thereof to both form therein a plurality of closely spaced narrow longitudinal corrugations and laterally stretch the material of the web to form therein closely-laterally-spaced narrow zones of lesser thickness extending longitudinally of the web wherein the fibers of the web material are loosened and exposed to provide projecting fiber ends and a plurality of discontinuous longitudinal tears without substantially impairing the longitudinal continuity of the web.
