  • Patent number: 9408414
    Abstract: Embodiments provide cigarette rolling and forming devices that include parallel cylinders extending between a pair of support plates, and a looped belt trained therearound. One cylinder is moveable relative to the other via a pair of curvilinear slots, and the device is configured for alternately receiving and compressing loose tobacco into a tobacco rod with the belt. In some devices, a nozzle is provided to allow longitudinal displacement of the formed tobacco rod into a pre-formed cigarette tube, and some devices include a pushing device to effect this longitudinal displacement. In some embodiments, a light source is provided and configured to illuminate a portion of the device, such as the nozzle or the recess between the cylinders. In various embodiments, the device also may include a power source configured to provide power to the light source and an activation member, such as a switch or button, configured to activate the light source.

  • Patent number: 8322349
    Abstract: Cigarette rolling and forming devices include parallel cylinders extending between a pair of support plates, and a looped belt trained therearound. One cylinder is moveable relative to the other for alternately receiving and compressing loose tobacco into a tobacco rod with the belt. In some devices, a pair of slots allows movement of the cylinder, and guard plates are disposed to prevent tobacco from the belt from entering the slots. Some devices include two pairs of slots and two moveable cylinders. Some devices include a support trough disposed to prevent sections of the belt from contacting each other. Some devices include a folding device configured to engage and fold the edge of a piece of paper received between the cylinders and rolled around the tobacco rod. Some devices include a nozzle to retain a pre-formed tube and a pushing device adapted to push a formed tobacco rod into the tube.
