A tobacco smoke filter having a non-integral core of components [2, 3] joined and held in longitudinal alignment by a strip [1] which extends only partially around the core circumference to leave a gap [7] extending longitudinally of the core between the longitudinal edges [8] of the strip, and an outer wrap [5] which engages fully around the core and strip and provides-e.g. via perforations [9]-for the lateral ingress of external ventilating air therethrough and through the longitudinal gap. |
