ABSTRACT:
A testing device for testing the ends of cigarettes, particularly to detect any tobacco ends which are inadequately filled with tobacco, comprises a light source arranged to direct a beam of light onto the ends of successive cigarettes, and a light detector which responds to a light signal which results from the beam of light and is dependent upon the quantity of tobacco in the ends of successive cigarettes (in the case of tobacco ends) or on the presence of a filter in the case of a test on the filter ends of filter-tipped cigarettes.
