This device utilizes a system of punching rectangular holes along the spine of a document and then using metal hoops, often referred to as “double-loop wire” or “wire-o,” to bind the pages together. A common example is the binding frequently found in calendars, notebooks, and reports.
This binding method offers a professional and durable finish, allowing documents to lay flat for easy reading and note-taking. Its clean appearance and the ability to easily turn pages make it a popular choice for presentations and reports. Developed as an alternative to more cumbersome methods, this technology streamlined the process of document binding, enabling quicker and more efficient production. This has contributed to its widespread use across various industries, from education and business to print finishing and personal organization.
