ABSTRACT:
A multi-sectional filter tip assembly is initially made with two charcoal filter sections and alternate sections of cellulose acetate fibrous material with a fibrous section at each end. The filter tip assembly is then compacted by a pin compactor which punches a recess into each fibrous end of the filter tip assembly while at the same time forcing the displaced acetate fibrous material into the charcoal sections to compact the charcoal. Upon removal of the pins of the pin compactor, a recess is formed in each end of the filter tip assembly.
