Abstract

L'invention concerne un procédé de façonnage de bouton pression qui permet de réduire les coûts de production de la fixation à pression et la charge de travail due au contrôle des stocks. On obtient un élément intermédiaire de fixation (10), qui présente une partie inférieure (11) en forme de disque et une partie latérale (12) cylindrique qui se dresse sur le bord extérieur de la partie inférieure (11) dans la direction radiale. Ensuite, on déforme la partie latérale (12) de l'élément intermédiaire de fixation (10) pour constituer sélectivement et selon les souhaits un bouton pression mâle (40) ou un bouton pression femelle (30). L'élément intermédiaire de fixation (10) peut être réalisé en métal. On peut faire fonctionner l'élément intermédiaire de fixation (10) sur le bouton pression mâle (40) ou le bouton pression femelle (30) quand l'élément intermédiaire de fixation (10) est fixé à un tissu (15).
