Abstract
Apparatus for applying adhesive foam or other liquid-based ingredients to the ends of cigarettes includes a source of suction, a device for carrying and moving a series of flexible tubular sealing members 50 each of which is aligned with a respective cigarette in a treatment station, and an arrangement for moving each sealing member into engagement with a respective cigarette and for connecting each sealing member to the source of suction, characterised in that each sealing member is so shaped that an end portion 54 thereof can engage around the end portion of the corresponding cigarette, and that suction transmitted through the sealing member causes the end portion of the sealing member to contract and thus grip the cigarette. A pressure air source may also be included to expand each sealing member as it moves over the end of the corresponding cigarette.
