ABSTRACT:
The diameters of successive rod-shaped articles of the tobacco processing industry are ascertained while the articles advance sideways at the periphery of a rotary drum-shaped conveyor and are rotated about their longitudinal axes as a result of frictional engagement with a rolling member which is adjacent the periphery of the conveyor. Successive articles which are being rotated by the rolling member are caused to interrupt a beam of radiation issuing from a laser, either once or more than once, and the amounts of intercepted radiation are indicative of the diameters of the respective articles. Such amounts of intercepted radiation are monitored by a video camera which generates electric signals, and the electric signals are processed into second signals denoting the diameters of discrete successively tested articles and/or the average diameters of series of two or more successively tested articles.
