发明名称 METHOD OF MAKING A PAPER CLIP
摘要 The method of making a paper clip (17) to secure sheets of paper together includes placing the overall configuration of the paper clip on the exterior planar surface of a thin sheet (12) of metal or composite with the configuration of the paper clip including a pair of spaced-apart, normally triangularly shaped wings (18, 20). Severing the exterior edges (28, 30) of the wings from the sheet of metal. Partially deflecting the wings from the sheet of metal along bend lines (52, 54) to a canted position relative to the sheet of metal and with the further possibility of deflecting 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 (62) of the paper clip and removing of the paper clip (17) from the sheet of metal.
