  • 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.
