DEVICE IMPARTING ADHESIVE TO STAMPED SEAL PAPER INSERTED IN PACKAGE

摘要

PURPOSE: To apply glue to closure stamps for insertion onto packages such as cigarette packs so as not to jut out therefrom. CONSTITUTION: A pair of rotary glue-applying wheels 34A receive the glue from a glue pot 28 and transfer the glue onto the backs of the closure stamps when the closure stamps are fed through the glue-applying wheels. A portion 60 of the peripheral edge of each glue-applying wheel 34A is radially inwardly recessed to form an interruption in an outer diameter of the peripheral edge so that only a nonrecessed portion of the outer edge transfers the glue to the closure stamps. Thus both 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 a closure stamp-feeding mechanism 12 and the glue-applying wheels 34A to ensure that the glue lines are kept spaced.
