Method and apparatus for applying glue to blanks for packs

In order to create optimum operating conditions for gluing aggregates (16), the glue is maintained by heating in the gluing aggregate (16) at an optimum operating temperature. For that purpose, the gluing aggregate (16) is provided with a heating system which consists of an electric heating cartridge (25) applied on the gluing aggregate (16). The heating cartridge (15) is controlled by a thermosensor (28).
