<p>A method of electro-optically inspecting cigarettes, whereby the cigarettes are fed along a route defined by two counter-rotating conveyors, each having substantially cylindrical peripheral seats designed to cooperate with opposite halves of the lateral outer surface of the cigarettes. The exposed surface portion of each cigarette is inspected by an electro-optical device, such as a telecamera, as it travels over each conveyor, and the end of the cigarette inspected by at least a further electro-optical device; the resulting images produced by the aforementioned electro-optical devices being compared with a specimen image, and the result of said comparison being employed for determining acceptance or rejection of each cigarette.</p> |
