Abstract
A filter component cutting system comprises a supply hopper of elongate filter rods and a cutting drum with spaced apart flutes on an exterior surface of the drum for receiving the elongate filler rods. A transfer mechanism receives the elongate filter rods from the supply hopper and delivers the rods to the flutes on the cutting drum. At least one cutter adjacent the cutting drum functions to cut the filter rods in to individual filter components as the cutting drum rotates.
