A metallic gasket for use in an internal combustion engine has seals around the gasket openings which are formed by a two-step coining operation plus a folding operation. The gasket has a base plate including a folding portion located between an edge of an opening and a fold line. A channel and a reduced thickness portion are formed in the folding portion by a first coining operation. The channel is spaced from the edge of the opening and spaced from the fold line. Next the folding portion is folded back onto the base plate of the gasket. Finally, a second coining operation takes place to flatten the folded seal to a final thickness and produces material flow between the base plate and the folding portion.
L'invention concerne un joint de culasse métallique destiné à un moteur à combustion interne. Le joint comporte des garnitures d'étanchéité autour des ouvertures qui sont formées par une opération de matriçage en deux étapes et une opération de pliage. Le joint est doté d'une plaque de base comprenant une portion pliante entre un bord d'une ouverture et une ligne de pliage. Un profilé et une partie plus mince sont formés dans la partie pliante par une première opération de matriçage. Le profilé est espacé du bord de l'ouverture et de la ligne de pliage. La partie pliante est ensuite repliée sur la plaque de base du joint. Enfin, une seconde opération de matriçage permet d'aplanir la garniture pliée à une épaisseur définitive.
