GLUE TRANSFER APPARATUS FOR CIGARETTE FILTERS Abstract of the Disclosure A filter is formed by placing increments of glue in spaced apart relation on a moving stream of plug wrap paper and thereafter depositing alternating fibrous filter sections on the glue increments. Particulate material is then de- posited between the fibrous filter sections and the plug wrap paper wrapped about the filter sections to form an endless rod. Two-filter filter plugs are severed from the rod by cutting through the unglued fibrous filter section and there- after the charges of particulate filter material are compacted by moving the unglued outer filter sections of each plug in- wardly. Each plug is then joined to two tobacco columns and cut in half. The resultant filters each have a fibrous filter section at the exposed end glued to the plug wrap paper, a com- pacted particulate section and an unglued fibrous filter sec- tion at the tobacco end.
