Abstract
A method of fabricating a smoking article filter element includes arranging a corrugated laminate web around a portion of filter material having an elongate shape and a longitudinal axis, such that the grooves and ridges of the laminate web run in the same direction as the longitudinal axis of the filter material. A method of fabricating a smoking article involves the same method as that of fabricating a smoking article filter element.
