Abstract

On décrit un procédé pour la fabrication d'un couvercle en tôle pour boîtes, ce couvercle comportant au moins une languette d'ouverture pouvant ëtre foncée vers la face intérieure du couvercle, ce procédé comprenant les étapes opératoires suivantes : - former un bombement dirigé vers le haut, - découper partiellement à l'emporte-pièce la languette d'ouverture en ménageant une zone de jointure, - décaler la languette d'ouverture vis-à-vis de la zone marginale de l'ouverture sur la face intérieure du couvercle, - amener, par formage final, la zone marginale de l'ouverture et/ou de la languette d'ouverture à la forme définitive, éventuellement estamper également la zone marginale de la languette d'ouverture, de telle sorte que la zone marginale de l'ouverture recouvre, sur une zone annulaire, la zone marginale de la languette d'ouverture sur la face extérieure du couvercle. Au cours de toute l'étape de formage final et éventuellement au cours de l'estampage, les deux zones marginales sont maintenues mutuellement à une distance axiale l'une de l'autre.
