Abstract
A rod for use in a smoking article comprises a gathered sheet of homogenised tobacco material circumscribed by a wrapper. The sheet of homogenised tobacco material may comprises one or more aerosol-formers and have an aerosol former content of greater than 5% on a dry weight basis or of between 5% and 30% by weight on a dry weight basis. The rod may comprise a continuous element to which one or more additives have been applied, which is incorporated into the gathered continuous sheet of homogenised tobacco material. A method of forming the rod comprises the steps of: providing a continuous sheet of homogenised tobacco material; gathering the continuous sheet of homogenised tobacco material transversely relative to the longitudinal axis thereof; circumscribing the gathered continuous sheet of homogenised tobacco material with a wrapper to form a continuous rod; and severing the continuous rod into a plurality of discrete rods. The sheet of homogenised tobacco material is preferably crimped or otherwise textured.
