Zusammenfassung:	Cigarette packets are assembled by a method that involves dabbing or spraying a cold-setting adhesive (8) onto selected areas (8a, 8b) of a blank (3) fed along the wrapping line (1) of a packaging machine, whereupon the blank (3) is folded to form a packet (2); should there be a break in operation of the machine following the application of the adhesive (8), persisting for a certain length of time (T), the method includes a heat-reactivation step whereby the adhesive (8) applied previously to the blank is warmed to a given temperature so as to restore its bonding properties and guarantee the ultimate stability of the assembled packet (2).
