Abstract
Successive packets of cigarettes or the like are monitored to ascertain the integrity or absence of integrity of their outer envelopes by conveying them across at least one curtain of radiation so that a packet having an improperly glued flap or tuck or label or an analogous defect affecting the acceptability of its outline intercepts a greater amount of radiation than a packet having an outline matching that of a prototype. First signals denoting the amount of radiation intercepted by successive packets are compared with a reference signal denoting the amount of radiation intercepted by the prototype and, when the difference between a first signal and the reference signal is outside of a permissible range, the corresponding packet is segregated from other packets.
