Abstract: A method and apparatus is disclosed for the manufacture of J-shaped display hooks with balled ends in a single manufacturing operation, without requiring separate handling of the display hook for the bending and ball-forming operations. A continuous length of wire is advanced incrementally and gripped tightly adjacent its forward end. The wire is severed by a cutting and forming bar, which also bends the base portion of the wire at right angles to the main axis of the wire. While the wire remains tightly gripped at its forward end, and continue to be supported adjacent its base by the cutting and forming bar, a ball-forming die is advanced against a projecting forward end of the wire, upsetting the wire end and forming an enlarged end of generally spherical configuration. Immediately thereafter, the wire is released at its forward end, and a rotary plate is actuated, causing a bend-forming element to travel through a generally circular path concentric to a cylindrical forming drum.

Abstract: A drawing machine for drawing a workpiece (41) comprises first and second drawing dies (42, 43), first and second push rods (45, 46, 47, 48) and first and second junction rods (53, 54). When the first push rods (45, 46) are downwardly moved, the first junction rod (53) is pressed and moved by the first push rod (45) to press the first drawing die (42). Consequently, the first drawing die (42) forms a first-stage drawn part in the workpiece (41).
