Abstract
Cigarette packets of a file wherein packets having satisfactory envelopes are randomly distributed among packets with defective envelopes, particularly envelopes having improperly glued and/or loose flaps, are advanced by a belt conveyor between two laterally adjustable guides. The guides bear upon the adjacent fold lines for pairs of mirror symmetrical flaps with a force which suffices to intensify the defects of envelopes with one or more non-adhering or improperly adhering flaps. This facilitates subsequent detection and segregation of packets having defective envelopes.
