Wire binding is a popular commercial book binding method, and is known by various names, including double loop wire, double-o, ring wire, twin loop wire, wire comb, wire-o, wirebind and wiro. With this binding method, users insert their punched pages onto a C-shaped spine , and then use a wire closer to squeeze the spine until it is round. [ 1 ]
Spiral Binding Company, started in 1932, was "the first mechanical binding company in the United States". [2] It created the original metal spiral-coil binding and later the Spiralastic, a popular plastic coil to replace wire during World War II. [3]
To keep the wire taut when changing the product, it is fixed to a wire parking pin of the machine. This wire parking pin can either be a clamp or a copy of a post that is wrapped at the coil similar to the termination process. Before the winding starts and after terminating the start wire post, the wire to the parking pin needs to be cut.
Comb binding (sometimes referred to as "cerlox" or "surelox" binding) is one of many ways to bind pages together into a book. This method uses round plastic spines with 19 rings (for US Letter size) or 21 rings (for A4 size) and a hole puncher that makes rectangular holes.
Next the wire is passed out through the capillary and the machine moves over a few millimeters to the location that the chip needs to be wired up to (usually called the leadframe [3]). The machine again descends to the surface, this time without making a ball so that the wire is crushed between the leadframe and the tip of the capillary.

Some advantages of cold heading a part over using a CNC lathe or Swiss screw machine include reduced part cost both through production speed (60-400 parts per minute) and the minimal scrap generated from a cold headed part. Also, because the part is formed rather than cut, the grain flow stays intact and creates a much stronger part for its ...
