摘要： A method of producing a multi-component filter or multiple component filter rod comprising the steps of : arranging alternating cylindrical plugs of a first filtering material (22) and a second filtering material (14) so as to provide groups of three plugs comprising a plug of first filtering material abutted at either end with a plug of second filtering material, each such group longitudinally spaced at each end from a plug of first filtering material; introducing a particulate additive into the space (301) between each group of three plugs and each single plug; applying a filter wrapper material around the cylindrical plugs and particulate additive to form a continuous rod of wrapped plugs and particulate additive; and cutting the continuous rod across the plugs of first filtering material.
