<p>This invention is concerned with the manufacture of double cigarette units each consisting of a double-length tobacco rod having filters secured to its opposite ends. Cutting in half of such double cigarettes units to form separate filter cigarettes may be delayed until just prior to packing of the cigarettes, until which time the filters at the ends of the double cigarette units seal in the tobacco. The manufacture of double cigarette units according to this invention is an in-line process in which double tobacco rods (16A) and intervening double filters (18A) are joined by portions of tipping paper (20) while moving axially so as to form a continuous rod which is then cut through the middle of the double filters to produce the specified double cigarette units (24A).</p> |
