INCORPORATION OF SMOKE-MODIFYING AGENTS IN SMOKING MATERIAL RODS

摘要

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 (1). The longitudinal feed path in the machine is in a travel direction of the smoking material deposition run of the suction band (3) of the machine. The fibriform material (13) is either constrained by guide means (15) in the machine to follow a feed path spaced from the run (31) 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 (20) deposited on the run. Thereafter further smoking material (20') is deposited on the deposition run.
