ABSTRACT:
A wire straightener is provided which uses three roller sets in one plane to apply deflection forces to a wire, which may have bends or coiling memory in more than one plane, so that the wire exits the wire straightener essentially straight, and free of bends or the tendency to coil and kink. The wire straightener adjusts for changes in pull angle as a means of accommodating different sizes of wires, by freely rotating around a pivot point, so that the amount of wrap of a wire around the last roller automatically adjusts. The wire straightener can straighten more then one wire at a time, and has multiple wire guides for feeding the wire onto the rollers. It is designed so that the wire may be threaded onto the wire straightener in the middle of a length of the wire, without having to feed the wire on using the end of the wire. The wire straightener is adapted for use with wire which has been wound onto a cylindrical spool for storage and dispensing. The wire straightener can be mounted to a frame, or to any pivot point, such as a bolt or a nail driven into a solid object.
