Abstract
A method of incorporating fibriform smoke-modifying material in smoking material rod, wherein fibriform smoke-modifying material is fed longitudinally thereof to a rod making machine ( ). The longitudinal feed path in the machine is in a travel direction of the smoking material deposition run of the suction band ( ) of the machine. The fibriform material ( ) is either constrained by guide means ( ) in the machine to follow a feed path spaced from the run ( ) of the suction band against the suction force towards the run or the feed path of the fibriform smoke-modifying material is caused to ascend toward the deposition run under the influence of the suction force towards the run, until at a predetermined distance along the deposition run the fibriform material becomes supported and is subsequently maintained at a predetermined distance from the run by particulate smoking material ( ) deposited on the run. Thereafter further smoking material ( ′) is deposited on the deposition run.
