  • Patent number: 10321709
    Abstract: Filter rods for use in the manufacture of cigarette filter elements are provided, with each rod having a longitudinal axis and incorporating a generally longitudinally extending filter material and a generally longitudinally extending strand within that filter material. A filter making unit receives a continuous supply of a filter material, and forms the filter material into a gathered composite having a continuous cylindrical shape. A continuous supply of a strand (e.g., colored thread) is provided and is introduced into the filter material gathered composite in the tongue of the filter making unit. The filter material and continuous strand positioned therein are formed into a continuous rod having the strand material laterally positioned within that rod, and the continuous rod is subdivided at pre-determined longitudinal intervals to provide a plurality of rod portions.

  • Patent number: 10117454
    Abstract: Provided herein is a tobacco recovery machine that automatically removes and separates a tobacco rod from formed cigarettes and slits the tipping paper surrounding the tobacco rod. The tobacco recovery machine includes a hopper that receives cigarettes. A feed mechanism individually feeds the cigarettes from the hopper and through a chopping mechanism that removes the filter rod from each cigarette leaving the cylindrical tobacco rod wrapped in the tipping paper. The tobacco recovery machine next feeds the tobacco rod of the cigarette through a slitting mechanism that slits the tipping paper wrapping surrounding the tobacco. The slitting mechanism axially slits the tipping paper along the tobacco rod such that the tobacco product can separate from the tipping paper.

  • Publication number: 20180140002
    Abstract: A system for simulating ash removal from a smoking article and a related method are provided. The system includes a support arrangement supporting at least a portion of a smoking article to form a cantilever with respect to the support arrangement. The system also includes a suction device in fluid communication with the first longitudinal end of the smoking article, the suction device being configured to apply suction to the first longitudinal end to simulate a draw or puff on the smoking article. The system further includes an ignition device configured to ignite an ignitable material of the smoking article about the second longitudinal end thereof, the ignited ignitable material being transformed to an ash in response to successive draws or puffs applied by the suction device. The system still further including an ash-dislodging mechanism configured to selectively impact the cantilevered smoking article to periodically remove the ash.

  • Publication number: 20160120213
    Abstract: A smoking article production apparatus and method for producing smoking articles is provided, each smoking article including serially engaged filter rod and tobacco rod sections. A rotatable drum includes a longitudinally-extending receiving surface defining a plurality of channels for receiving smoking articles arranged parallel to the longitudinal axis of the drum. An inspection device is arranged to inspect each smoking article in the channels of the drum and to determine whether any of the smoking articles are defective. Any defective smoking articles are directed away from the drum. A rotatable sampling drum is in communication with the drum and is configured to receive defective smoking articles therefrom. A severing device is disposed adjacent the sampling drum to sever each defective smoking article to separate a portion of the tobacco rod section from the remainder of the defective smoking article including the filter section. An associated method is also provided.
