Abstract

A method for manufacturing cigarette filter rods comprises providing a continuous supply of filter material in a direction of travel; forming the filter material into a continuous rod; and rotating a wheel in a vertical plane, in operable communication with the filter material such that a portion of the wheel contacts the filter material at a predetermined location, and such that general direction of travel of the rotating wheel and the filter material, when in contact, are in generally the same direction. The method also comprises providing a lower hopper in operable communication with the rotatable wheel; providing an upper hopper in operable communication with the lower hopper; and wrapping an overwrap material around the filter material. The method further comprises controlling speed of rotation of the wheel relative to feedback from an inspection system; and subdividing the continuous rod at pre-determined intervals.
