Abstract (en)
In order to obtain a leak-free and mechanically stable joint between the helically wound wrapper (7) and the mouthpiece paper (10a) which surrounds the filter, the latter has been divided into an inner filter plug (4a) abutting against the end face of the bunch (3a) and an outer filter plug (9a) located in extension of the inner plug. An additional, interior mouthpiece paper (5a) surrounds the inner filter plug (4a) and a portion of the bunch (3a), and the wrapper (7) is retained between the two mouthpiece papers (5a, 10a) and supported from inside by the inner filter plug (4a). In the method a double filter plug is first placed between two bunches and an interior mouthpiece paper is applied. A wrapper is rolled around the entire length of the resulting double bunch which is then severed to form two single bunches. A further double filter plug is placed between the single bunches where-upon an exterior mounthpiece paper is applied. Finally the product is severed in the middle.
