A method for applying an adhesive to a packaging material, the material being conveyed during the application of an adhesive in the form of a separate blank or a continuous strip of material for the production of a blank for a package, such application being by means of an adhesive nozzle (24) The nozzle is provided with a closable nozzle opening (25, 26). During the stage of applying the adhesive to the packaging material, the opening is supplied with adhesive at pressure-adhesive pressure, which is characterized by: The adhesive pressure to the adhesive can be adjusted on a separate basis, the basis of which is the speed of transport of the packaging material or strip (21) and/or the viscosity of the adhesive, and/or the area of ​​the adhesive applied to the packaging material. - The thickness of the adhesive layer of the adhesive zone (16) and adhesive strip (20) - as determined.
During the application of the adhesive, in particular the hotmelt adhesive, to the material web (21) used for the blank, the adhesive transfer depends on the transport speed of the material web (21) and other parameters. In particular, the adhesive pressure, which is applied to the adhesive in accordance with the movement of the material web, is adjusted by means of a pressure control valve (37) which is connected to the central packaging machine controller (31). This ensures uniform distribution of the adhesive.
