Abstract

A filter attachment machine includes a fluted drum which is arranged to receive double filters and double cigarettes. A knife cuts the double cigarettes through the middle to form separate cigarette portions and, with the aid of a further drum, the two cigarette portions associated with each double filter are swopped in position so as to lie at opposite ends of the double filter, displacement of one of the cigarette portions being achieved preferably by displacing the associated double filter which in turn pushes the cigarette portion. The double cigarettes may be delivered axially into the flutes of the first drum from a cigarette making machine, preferably after delivery of the double filters which can then serve as resilient buffers for the incoming double cigarettes.
