AbstractThe diameters of successive rod-shaped articles of the tobacco processing industry are ascertained while the articles advance in the flutes of a conveyor, first along a rolling unit which turns successive articles at random through different angles and thereupon past a photoelectronic detector wherein a radiation source emits a narrow beam of radiation which impinges upon successive articles for intervals of time which are dependent upon the diameters of the articles. The transducer of the detector generates signals which are indicative of the monitored diameters, and such signals are transmitted to an evaluating circuit which controls an ejector for unsatisfactory articles and/or displays the monitored diameters on a screen. The articles are partially lifted off the conveyor by cushions of compressed air during transport past the rolling unit.
