Book Printing Lingo: What is Coil Binding?

The book’s cover and pages are held together by a spring-like coil that is spiraled through small holes punched along the spinal edge of the book.

Coil Binding, also known as Spiral Binding, is a very popular and relatively simple bookbinding method. The coil binding process secures the pages and cover of a book using a durable plastic or metal coil that resembles a long spring.

The coil is inserted and twisted through small holes punched along the spinal edge of the book’s cover and pages. After being fed through all the holes in the cover and pages, the coil is crimped at both ends to keep it in place.

Unlike most other binding styles, coil bound pages have no spinal tension in them. Hence, the pages of a coil bound book rotate around the coil with very little resistance. This allows the pages of a coil bound document to stay put without having to be continually held open to view the contents.

Coil binding is also one of the few bookbinding styles that allow a book to fold all the way back upon itself and yet still remain flat. Because this feature allows a book to be referenced easily while taking up minimal room on a desk or table, the coil binding method is an excellent choice for reports, sales presentations, proposals, directories, cookbooks, instructional books and maintenance manuals. Atlases and travel guides are also commonly coil bound because they are easier to manage when traveling. Also, since coil bound books open fully, important information never gets buried near the spine.
