Abstract
An apparatus used for the paper clip making machine downstream of the cutting machine comprises, a set of conveyors including continuous belt continuous chains, transferring wheels for advancing the cut wires, pieces of magnet properly located on the conveyors for attracting and arraying the cut wire in a proper orientation, three annular members spaced apart and mounted for rotation on the same axis, each of the annular members having a plurality of forming die member on the rim thereof for receiving and engaging cut wires, three segmented ring members of different lengths provided along the circumferences of corresponding annular members, ramming means provided at two sides of the annular member assembly adapted to exert bending forces on cut wires in the direction parallel to the axis of the annular member, the die members intermittently rising from the rim of the annular member to cooperate with the ramming means to bend the cut wires about the segmented ring members.
