spiralbinding

Spiral binding, also known as coil binding, is a common method for binding pages together. It uses a durable plastic or metal coil that is threaded through a series of punched holes along the edge of the document. The coil is continuous and can be spun around 360 degrees, allowing the bound pages to lie flat when opened. This feature makes it ideal for documents that are frequently referred to, such as reports, notebooks, and manuals.

The process typically involves a binding machine that punches the required holes and then inserts the spiral coil. The holes are usually circular or oval and spaced evenly along the binding edge. The coil itself comes in various diameters, allowing for binding of different thicknesses of documents. Once the coil is inserted, its ends are usually crimped to prevent it from unravelling.

Spiral binding is known for its durability and flexibility. The plastic coils are less likely to kink or break compared to metal coils, while metal coils offer a more professional appearance. This binding method is a cost-effective solution for producing professional-looking documents that require frequent use. It is widely used in academic, business, and personal contexts.
