ABSTRACT:
This invention relates to a method for delivering free-flowing material into discrete receiving spaces separating filter plugs in partially constructed cigarette filter assemblies. The method entails rapidly feeding a free flowing material such as charcoal into partially constructed cigarette filter assemblies. The free flowing material is dispensed to a first conveyance means and is subsequently transferred to a second conveyance means that is positioned parallel and above the first conveyance means. Vacuum is used to hold the free flowing particulate material onto the first conveyance means and is used to transfer the free flowing material to the second conveyance means and to hold it there. The free flowing material is next transferred into receiving spaces formed between articles such as cigarette filter plugs that are disposed on a third conveyance means. The transfer of the free flowing material to the receiving spaces may also be accomplished by use of vacuum or gravity.
