Plain or filter cigarettes are tested at a first station by two or more testing devices each of which monitors the cigarettes for the presence or absence of a particular defect. The testing devices generate defect signals which are delayed by shift registers so as to ensure that the delayed defect signals are transmitted to a segregating mechanism which removes defective cigarettes from a path that is common to the satisfactory and defective cigarettes and delivers defective cigarettes to selected receptacles which are installed at a second station and each of which gathers only cigarettes exhibiting a particular defect. Actuation of a switch entails the removal of a selected number of samples from the common path for satisfactory and defective cigarettes, and such samples are gathered in an additional receptacle at the second station.

Apparatus for testing and classifying cigarettes or the like

Two cigarette making machines discharge discrete files of coaxial plain cigarettes which are moved axially in parallel guides, and successive foremost cigarettes in each guide are engaged and accelerated by a discrete rotating cam which propels the cigarettes into the oncoming axially parallel peripheral flutes of a rotating drum-shaped conveyor. Each flute receives a cigarette from each of the two guides and the distance between a pair of neighboring flutes on the conveyor exceeds the distance between the two files of cigarettes.
