Abstract
Filter mouthpieces with one or more thin filter disks consisting of a first filter material and one or more filter plugs consisting of a second filter material are produced by inserting filter disks between spaced-apart filter plugs which form a single file and travel with a web of wrapping material. The web is thereupon draped around the alternating filter disks and filter plugs to form therewith a continuous filter rod which is severed to yield discrete filter mouthpieces.
