Abstract
Rods are manufactured by shredding strips of sheet-like reconstituted tobacco material into a plurality of strands of about 1/32 inch width. The strands are gathered into a rod-like shape and circumscribed by paper wrap in order to provide a continuous rod. The continuous rod is severed at regular intervals to provide a plurality of rods of the desired length. The resulting rods have a plurality of substantially longitudinally extending strands provided from shredded sheet-like material. The rods are useful as cigarette rods or in the manufacture of cigarette filter elements.
