Abstract
A cigarette filter subassembly is manufactured from a filter member having absorbent material encased within an outer cover. A plunger is passed axially through the absorbent material such that a pointed leading end of the plunger displaces the absorbent material radially outwardly against the cover to form a liner of compressed absorbent material along the cover's inside surface. An inner surface of the liner surrounds a hollow axial opening which is to receive absorbent members and capsules inserted axially therein. The capsules are adapted to be broken by a smoker to release an additive material which modifies characteristics of tobacco smoke. An outer cylindrical surface of the plunger optionally carries a transferable binder material that becomes smeared onto the inner surface of the liner to form thereon a coating which is impermeable to the additive material released from the capsule.
