ABSTRACT:
The invention is directed to an inspection method, apparatus and system for identifying cigarettes having insufficient tobacco at their lighting end in which cigarettes are conveyed serially through a beam of infrared radiation. The amount of infrared radiation passing perpendicularly through the end portion of each cigarette is compared to a predetermined value to determine whether or not the cigarette is defective. The method, apparatus and inspection system of the invention is both accurate and reliable and can be employed in combination with cigarette manufacturing systems operating at speeds in excess of 7,000-8,000 cigarettes per minute.
