Abstract
A cigarette comprises a filter element having an air-permeable surface and a tobacco rod, the filter element and the tobacco rod being interattached by an air-impermeable tipping wrapper. The tipping wrapper is attached to, but spaced from, the underlying peripheral surfaces of the tobacco rod and the filter element at first zones extending from the upstream edge of the wrapper across the rod/element juncture and is unattached and spaced from the peripheral surfaces at second zones circumferentially intermediate the first zones. There are thus provided ventilation air inlet ducts through which air is able to enter the filter element without the necessity for tipping wrapper perforations.
