A rod for use in a smoking article is provided, the rod including a gathered sheet of homogenized tobacco material circumscribed by a wrapper. The sheet may include 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 include a continuous element to which one or more additives have been applied, which is incorporated into the gathered continuous sheet of homogenized tobacco material. A method of forming the rod includes providing a continuous sheet of homogenized tobacco material; gathering the continuous sheet transversely relative to the longitudinal axis thereof; circumscribing the gathered continuous sheet with a wrapper to form a continuous rod; and severing the continuous rod into a plurality of discrete rods. The sheet is preferably crimped or otherwise textured.
