Abstract

The apparatus is provided with a cutter having pairs or rotary knives for cutting a filter rod into plural filter plugs and a pin wheel for positively ejecting the filter plugs in spaced array onto a conveyor. The apparatus also has a rotary feed means for the granular filter material which employs an independently rotatable cam wheel with pins for pushing out the plungers of the feed wheel to expel the charges of granular filter material. The garniture also laterally compresses the filter plugs to form a restricted pocket between two filter plugs to receive the granular filter material.
