Abstract
Apparatus for testing the end portions of cigarettes to detect end portions containing insufficient quantities of tobacco has a conveyor which transports the cigarettes sideways past at least two testing stations each of which accommodates a discrete capacitive and/or photoelectronic testing unit. Repeated monitoring of the end portions of successive cigarettes reduces the likelihood that unsatisfactory cigarettes, particularly cigarettes with end portions which are empty or contain insufficient quantities of tobacco particles, would reach the consumers. Signals which are generated by the testing units can be used to segregate cigarettes having defective end portions.
