METHOD FOR MANUFACTURE OF CIGARETTES AND FILTER ASSEMBLIES WITH COMPRESSIBLE FLAVOUR CAPSULE Russian patent published in 2015 - IPC A24D3/02 

FIELD: tobacco industry.

SUBSTANCE: filter assembly (26) is manufactured of a filtering element having an absorbing material (112) confined in an external coating (52). A plunger (104) passes axially through the absorbing material so that the tipped front end (106) of the plunger (104) displaces the absorbing material (112) radially to the outside against a coating (52) so that to form a tube (42) of the compressed absorbing material along the coating inner surface (52). The inner surface of the tube (42) surrounds a hollow axial hole (114) that is to receive absorbing elements (130) and capsules (36) as may be placed axially therein. The capsules (36) are fitted to be destroyed by the smoker for release of an additional material modifying tobacco smoke properties. The plunger (104) external cylindrical surface optionally carries a relocatable interwoven material that is spread across the inner surface of the tube (42) so that to form a coating (43) thereon which is impermeable for the additional material to be released from the capsules (36).

EFFECT: method improvement.
