Abstract
Pour éviter l'écrasement des entretoises et l'affaissement des faces entre les entretoises lors de l'emboutissage, par formage par le vide ou par air comprimé ou par un moule et un poinçon, on ferme les canaux de façon étanche avant la mise en forme, par compression et/ou soudage des extrémités des canaux aux bords transversaux de la plaque ou par des éléments d'étanchéité. L'air ainsi emprisonné dans les canaux empêche l'écrasement pendant l'emboutissage. L'invention est notamment applicable à l'industrie automobile.
