  • Continuous gluing process of an adhesive composition with a gluing nozzle having an extrusion die with a relaxation volume
    Patent number: 10974431
    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 (20) comprising a lower lip (22) and an upper lip (24), the upper and lower lips (24, 22) extending parallel to one another so as to form a transverse channel (28) for the longitudinal flow of the adhesive composition, the transverse channel extending longitudinally between: a supply opening (30) for supplying the adhesive composition; and an extrusion outlet (34) for extrusion of the adhesive composition (34); the channel (28) comprising a concave volume (32) for relaxation of the adhesive composition between the supply opening (30) and the gluing outlet (34).
