Title: Method of making cigarettes and a cigarette made according thereto

Abstract: Method of producing 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. The method includes longitudinally grooving the web while preventing any substantial transverse contraction so as to form a plurality of closely spaced narrow longitudinal corrugations. The grooved web is then laterally stretched to form 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.
