Abstract

Blanks (10) for hinge-lid packs are provided with glue in the form of glue spots (29a to 29i). A plurality of rows (33 to 36) of the glue spots are distributed over the blank (10) in such a manner that the pack collar (84) and the inner wrapping (82) are sufficiently fixed, and that a lid inner tab (22) is permanently connected to a lid front wall (20). The glue spots (29a to 29i) are applied by a gluing unit (37) which can be removed as a unit from the packaging machine and which is connected to a glue container via a main glue line (56).
