  • REGISTERED BANDED CIGARETTE PAPER, CIGARETTES, AND METHOD OF MANUFACTURE
    Publication number: 20110108042
    Abstract: Registered banded wrapper, cigarettes using that wrapper paper, and methods of making cigarettes with that banded paper result in banded regions of cigarette paper which begin at substantially the same location on each cigarette. With the banded region positioned at a preferred predetermined distance from the end of the cigarette, cigarettes made with such paper exhibit a consistent and improved ignition propensity compared with random or quasi-randomly positioned banded regions.

  • Activated carbon fiber cigarette filter
    Patent number: 7552735
    Abstract: A cigarette filter for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter primarily comprises an activated carbon fiber filter section including a bundle of activated carbon fibers. Particulate adsorbent materials such as granules, beads or course powders may be dispersed amongst the activated carbon fibers to aid in removal of the gas phase constituents. Additionally, the activated carbon fiber filter section may be used in combination with a separate bed or beds of particulate adsorbent material. In one embodiment, the activated carbon fibers are positioned within a helical groove on the outside of a threaded rod within the activated carbon fiber filter section. Relatively smaller amounts of activated carbon fibers produce the same smoke constituent reduction as larger amounts of particulate adsorbent material.
