Abstract
A process and apparatus for producing filter cigarette tubes is disclosed. A string of filter plugs is advanced continuously in longitudinal abutting relationship to a separating and accelerating device comprising a rapidly rotating wheel having a pair of pins projecting from the circumference. The pins pierce a leading plug of the string and accelerate it away from the following plugs. This is repeated with successive plugs on successive rotations of the wheel. The spaced plugs are fed continuously onto an advancing tape of cigarette paper, the tape and spaced plugs are wrapped into a tube and the tube is cut continuously into cigarette lengths each having a plug at the end.
