The invention relates to the joining of flat products of metallic materials to be interconnected overlapping. The joining takes place in a roll nip into which the flat products to be interconnected are introduced at an acute angle. Before they are pressed on one another in the roll nip, they are heated on their facing surfaces by radiation energy, but not melted. By a suitable profiling of at least one roller generated surface or one flat product the surface pressing is limited to the zone of the overlap joint and any flow of material transversely of the direction of the overlap joint is prevented.
L'invention concerne l'assemblage de produits plats métalliques se chevauchant. Pour ce faire, on introduit les produits plats dans l'écartement formé entre deux cylindres à un angle aigu. Avant d'être pressés l'un contre l'autre entre les deux cylindres, ils sont chauffés par énergie rayonnante au niveau des surfaces se faisant face, sans être fondus. Par un profilage approprié du bandage d'au moins un cylindre ou d'un produit plat, la pression superficielle est limitée à la zone du joint à recouvrement, empêchant ainsi un flux de matière transversalement à la direction du joint de recouvrement.
