Wire binding is a well-known bookbinding technique that is very popular. Other names for wire binding include double loop wire, twin-loop wire, and wire bind. There are generally two types of wire binding available on the market.

The spiral binding, also known as coil binding, is one where the spiral runs along the paper sheet's edge. This binding allows for flat and 360-degree rotation. Spiral binding has curved spines. 

For the coil to glide smoothly through the paper's holes, it is necessary to shape the spines of spiral binding documents into a curve. Double-loop binding is another type. 

This binding uses spines in the "C" shape. A single hole in a book or paper set can be made with two spines. A person will find it difficult to press the spines into a circular shape to create a binding look for the paper set. This is why wire binding machines are used to close the spines and wires.

Two functions of wire binding are to punch holes in papers and close them with wires. Manual wire binding machines can be used if the binding requirements of an organization are low. They have a manual hole punch, wire closer, and a manual hole punch.

An electric binding machine with an electric punch and wire closer is best for medium binding requirements. A wire binding machine is used by binding shops and printers to separate the functions of binding and punching. These machines combine an automated punching system with an electric wire closing.
