Abstract
Tobacco smoke filter having an axially extending tubular outer member and an axially extending air permeable inner member therewithin. The inner member is formed of filaments or fibers bonded to each other at their points of contact. At a first position the outer surface of the inner member is in engagement with the inner surface of the outer member to at least substantially preclude axial passage of smoke therebetween while at a second position, longitudinally spaced from the first, the filaments or fibers are formed into a portion of substantially smaller cross section to leave a hollow space through which smoke drawn through the filter may pass.
