An apparatus for the testing of cigarettes is disclosed. In the packaging of cigarettes, it is necessary to test the cigarettes for correct formation, especially for a complete filling of tobacco. For this purpose, a testing unit is arranged within a cigarette magazine and has a plurality of vertical test shafts, in the region of which the cigarettes are tested by optoelectrical sensors. The intact cigarettes subsequently pass into a cigarette stock in free fall. Since the optoelectrical sensors are exposed to the heavy accumulation of dust thereon these sensors are disposed on movable carriers by means of which these sensors may be moved between a testing position and a cleaning position in which the sensors are cleaned by cleaning members. To guarantee an orderly fault-free transfer of the tested cigarettes to the cigarette store, guide shafts may preferably be formed underneath the test shafts as a continuation of these test shafts and lead to a point immediately above the cigarette stock. The guide shafts limited by vertical plane guide-shaft walls guarantee that the cigarettes are deposited in an orderly manner and without tilting.
