Abstract
A method and apparatus for compacting particles or granules in discrete cavities spaced along an article or articles such as a cigarette filter rod moved underneath the compacting system. The compacting system can be provided with spaced lugs or other protrusions that selectively compact particles within cavities, or a smooth outer periphery that results in progressive compaction of the entire article being moved underneath the compaction system. The article having cavities with particles that need to be compacted can be supported on a support rail with side support rails that maintain the shape of the article during the compaction process.
