Abstract

The invention relates to a gluing process of an adhesive composition with the use of a gluing nozzle having an extrusion die for continuous extrusion of an adhesive composition over a predetermined width, the extrusion die () comprising a lower lip () and an upper lip (), the upper and lower lips () extending parallel to one another so as to form a transverse channel () for the longitudinal flow of the adhesive composition, the transverse channel extending longitudinally between: a supply opening () for supplying the adhesive composition; and an extrusion outlet () for extrusion of the adhesive composition (); the channel () comprising a concave volume () for relaxation of the adhesive composition between the supply opening () and the gluing outlet ().
