An apparatus applies glue to closure stamps for insertion onto packages, such as cigarette packs. A pair of rotatable glue-applying wheels (34A) receive glue from a glue pot (28) and transfer the glue onto the backs of the closure stamps as the closure stamps are fed therepast. A portion (60) of the peripheral edge (40A) of each glue-applying wheel (34A) is recessed radially inwardly, to define an interruption in an outer diameter of the peripheral edge, so that only a non-recessed portion of the outer edge transfers glue to the closure stamps. In this way, opposite ends of the glue lines are spaced from leading and trailing edges of the closure stamp. A synchronizing mechanism is provided to achieve a proper synchronization between the stamp-feeding mechanism (12) and the glue-applying wheels (34A) to ensure that the glue lines are kept spaced from the leading and trailing ends of the closure stamp. <IMAGE> |
