  • Patent number: 4825883
    Abstract: A mass-producing filter tipping machine wherein two coaxial plain cigarettes of unit length are simultaneously severed to yield pairs of coaxial plain cigarettes of unit length which are moved apart to provide spaces for filter mouthpieces of double unit length. This results in the formation of two rows of groups of three coaxial rod-shaped articles each, namely, two plain cigarettes of unit length and a filter mouthpiece of double unit length between them. The filter mouthpieces are connected with the respective pairs of cigarettes of unit length by adhesive-coated uniting bands so that each filter mouthpiece and the respective pair of cigarettes of unit length jointly constitute a filter cigarettes of double unit length. Uniting bands are obtained from two discrete webs of adhesive-coated tipping paper.

  • Patent number: 4723561
    Abstract: A cigarette comprises a tobacco rod and a filter element of porous filtration material having an air permeable surface and equiangularly spaced lengthwise extending peripheral ventilation grooves. The element and the rod are interattached by a first air-impermeable wrapper which can extend into and line the grooves. A second wrapper is wrapped about the element and extends from the downstream end thereof for a distance short of the upstream ends of the grooves. The second wrapper does not line the grooves where it extends thereover. Ventilation air is then able to enter the upstream ends of the grooves not covered by the second wrapper and flow therealong. Ventilation is thereby achieved without the necessity for tipping wrapper perforations. A method of making such cigarettes is also disclosed.
