Abstract (en)
[origin: US4444227A] A mechanism for bending a coplanar family of straight wires into zig-zags comprises deflector rollers for feeding the family of wires longitudinally in parallel with one another, bars adapted to be displaced transversely to the wires and carrying wire deflector pins, and a control device for moving the bars alternately in opposite directions transversely of the wires. In order to avoid sliding of the wires against the deflector pins during the bending operation, each bar is hinged to the one ends of at least two parallel bearer arms of equal length and pivotally supported about axes running perpendicular to the plane of bend. During each bending operation only one bar at a time can be displaced transversely by means of the control device to carry out a working stroke.
