Abstract: Filter rods for use in the manufacture of cigarette filter elements are provided, with each rod having a longitudinal axis and incorporating a generally longitudinally extending filter material and a generally longitudinally extending strand within that filter material. A filter making unit receives a continuous supply of a filter material, and forms the filter material into a gathered composite having a continuous cylindrical shape. A continuous supply of a strand (e.g., colored thread) is provided and is introduced into the filter material gathered composite in the tongue of the filter making unit. The filter material and continuous strand positioned therein are formed into a continuous rod having the strand material laterally positioned within that rod, and the continuous rod is subdivided at pre-determined longitudinal intervals to provide a plurality of rod portions.
