  • 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.

  • Patent number: 5829453
    Abstract: A low-density filler material for cigarettes from either a low-density tobacco composition or an extruded grain or starch composition. The low-density tobacco composition and a method of making the low-density tobacco composition by extruding a mixture of tobacco and flour or tobacco and starch under conditions whereby the solvent in the extruded mixture flashes into vapor upon release from the extrusion head. The low-density tobacco composition is formed without the aid of an added binder. The low-density flour or starch material and a method of making it by extruding flour or starch with a filler material such as calcium carbonate under conditions whereby the solvent in the extruded mixture flashes into vapor upon extrusion through the orifice die. The extruded composition can then be cut and used in place of cut tobacco filler.

  • Patent number: 4832057
    Abstract: An apparatus for making a smokeable cigarette from a preformed inherently unsmokeable rod of tobacco and a separate sheet of cigarette paper provided with a strip of contact adhesive comprises an open-ended smooth bore resilient tube provided with a longitudinal slit defined by a pair of lips one of which is radially further spaced from the axis of the tube than is the other lip and is tangential to the circumference of the tube. In operation, the rod is inserted axially into the tube, the paper is then inserted into the slit and the rod rotated so as to wind the paper onto the rod. The user squeezes the tube so as to control the friction between the rod and the sheet. The sheet finally adheres to itself by means of the strip of adhesive. The invention also includes a booklet of cigarette papers which are mounted on the backing card by strips of contact adhesive. On removing a sheet from the card the strip of adhesive remains attached to the sheet.

  • Patent number: 4347855
    Abstract: A method of making smoking articles wherein a combustible tobacco material is mixed with one or more other ingredients including a liquid, the mixture being subjected to further processing to produce a shaped coherent mass having a through passage. Shaping is effected by application of pressure to the mixture to form the coherent mass, and is followed by drying of same, the mixture composition being selected and the shaping pressure and drying being controlled to impart to the shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of the shaped mass when ignited.
