Abstract

L'invention concerne un procédé permettant de fabriquer une gâche (1) de serrure pourvue d'un dispositif de sécurité en cas de collision, ce procédé consistant à "épaissir" la branche parallèle (6) par extrusion à froid au moyen d'un bourrelet de matière (15). Ce bourrelet de matière (15) est ensuite utilisé, après la formation de l'évidement (9), pour réaliser un bec (20) dans la région de la branche (7) correspondante de la boucle au moyen d'un outil de moulage par compression (16) introduit dans ledit évidement (9), de manière à obtenir une branche parallèle (21) rallongée uniformément.
