On divulgue une méthode de fabrication d'un apprêt adhésif composite, qui comprend les étapes suivantes: a) prévoir un appui conformable ayant des faces supérieure et inférieure, un adhésif sensible à la pression sur au moins une portion de la face inférieure de l'appui et un revêtement sur l'adhésif sensible à la pression; (b) fixer un support à la face supérieure de l'appui, le support ayant une coupe définissant une fenêtre à proximité du centre de l'appui, où le support sert de cadre autour d'une portion substantielle de la périphérie de l'appui, le cadre étant thermoscellé de façon amovible à la face supérieure de l'appui pour former une liaison entre le support et la face supérieure de l'appui qui est supérieure à la liaison entre le revêtement et l'adhésif sensible à la pression.
