The method of making a paper clip to secure a plurality of sheets of paper together which are located in a stacked relationship. The paper clip produced by the method of this invention comprises a rigid sheet material metallic or composite body which is bendable and when bent, remains in the bent position. The method includes placing the overall configuration of the paper clip on the exterior planar surface of a thin sheet of metal or composite with the configuration of the paper clip including a pair of spaced-apart, normally triangularly shaped wings. Severing the exterior edges of the wings from the sheet of metal. Partially deflecting of the wings from the sheet of metal to a canted position relative to the sheet of metal and with the further possibility of deflecting of the wings by forcing the wings to a side by side relationship with the remaining body of the paper clip. Severing the remaining exterior edge of the paper clip and removing of the paper clip from the sheet of metal.

L'invention concerne un procédé de fabrication d'un attache-feuille destiné à maintenir ensemble une pluralité de feuilles de papier empilées. Cet attache-feuille comprend un corps métallique ou composite réalisé dans une feuille rigide, qui peut être plié et qui, une fois plié, reste dans cette position. Le procédé de fabrication consiste à placer la configuration globale de l'attache-feuille sur la surface extérieure plane d'une fine feuille de métal ou de composite. Cette configuration comprend une paire d'ailes espacées, de forme normalement triangulaire. Ledit procédé consiste ensuite à séparer les bords extérieurs des ailes de la feuille de métal, à cintrer les ailes à partir de la feuille de métal vers une position inclinée par rapport à la feuille de métal et à cintrer en outre les ailes pour les amener en force à être adjacentes au reste de l'attache-feuille, et enfin à séparer le bord extérieur résiduel de l'attache-feuille et à retirer l'attache-feuille de la feuille de métal.
