Abstract

Des charnières roulées pourvues d'un volet de charnière qui comporte deux charnons extérieurs enserrant un charnon intérieur d'un second volet de charnière, sont fabriquées à partir d'un segment de plat de longueur inférieure à la longueur totale des deux volets de charnière. L'épaisseur de la zone médiane du segment de plat est diminuée par étampage à froid et éventuellement par étirement simultané. Les deux volets de charnière sont séparés l'un de l'autre par découpage, dans la zone médiane de moindre épaisseur, de languettes qui sont ensuite roulées pour former des charnons et fixées par leur extrémité roulée à la racine du charnon par une ligne de soudure.Rolled hinges provided with a hinge flap which has two outer hinges enclosing an inner knuckle of a second hinge flap, are made from a segment of a plate of length less than the total length of the two hinge flaps. The thickness of the middle zone of the flat segment is reduced by cold stamping and possibly by simultaneous stretching. The two hinge flaps are separated from each other by cutting, in the median zone of lesser thickness, tabs which are then rolled to form knuckles and fixed by their rolled end to the root of the knuckle by a line of welding.
