ABSTRACT:
A family of improved paper clips and a process for their formation is disclosed which comprises a central bridge leg joining two overlapping and contacting gripping jaws. Each gripping jaw lies in its own plane and controlled torsional forces in the legs comprising the jaws provide for independently controlled gripping forces at multiple tangential contact points. The controlled gripping forces and two layer planar shape result from a substantially elastic transformation from a preceding stepped helix wire form. The advantages include a firm grip on thin or thick packets, the ability to stay flat on thick packets of material, resistance to distortion, special features to aide application to thin or thick packets of material, and modest size facilitating its general purpose use.
