CA 2244453

Self-made cigarettes, i.e. cigarettes that are supplied in unsmokable condition in the form of a tobacco-bearing component attached to a porous filter or a portion of the surface of which is highly permeable, and an impervious tubular band carried on the component and slidable along it to cover the permeable region. The tubular band can be applied in a number of ways including compressing the tobacco-bearing component to slide a preformed tubular band onto it; using a fugitive adhesive to entrain a rectangular sheet to the surface of the tobacco-bearing component to form the band, dissipation of the adhesive subsequently rendering the tubular band movable; utilizing an adhesive strip by means of which the tobacco rod and the filter of the tobacco-bearing component are connected to carry a band forming sheet around the periphery of the component, the tubular band after its formation being readily separable from the connecting strip; and manufacturing the tobacco-bearing component in double length units with an additional allowance therebetween, utilizing that additional allowance to entrain a rectangular sheet of paper to wrap around the component to form tubular bands at opposite sides of the additional allowance, the latter thereafter being severed on both sides to form two non-smokable cigarettes each carrying a slidable tubular band thereon.
