ABSTRACT:
A filter element for use as a mouthpiece for filter cigarettes, cigarillos or cigars has an inner tubular wall with lugs which are bent inwardly from the material of the inner wall, and an outer tubular wall which seals the outer ends of openings which develop as a result of formation and bending of the lugs. The lugs and the two walls constitute a labyrinth for tobacco smoke, and the filtering action of the filter element can be enhanced by coating or impregnating the lugs and/or the inner wall with suitable chemicals which absorb or neutralize tar, nicotine and/or other deleterious ingredients of tobacco smoke. The filter element is made of a one-piece continuous paper web which is formed with lugs in a region adjacent to one of its marginal portions, which is thereupon folded over itself to form two layers, and which is thereupon converted into a continuous rod ready to be subdivided into filter elements of desired length. The outer wall of the rod has a longitudinally extending seam where one of its marginal portions overlaps and is bonded to the other marginal portion.
