The process of fastening pages together using a spiral coil, typically made of plastic or metal, to create a booklet or document is a common bookbinding technique. This method offers a durable and flexible way to combine sheets, allowing the finished product to lay flat or fold back on itself for ease of use. Examples include notebooks, calendars, reports, and manuals.
This binding method provides several advantages, including enhanced durability compared to some other binding styles. The ability of the publication to lay flat is particularly beneficial for reference materials or items requiring hands-free viewing. Historically, this binding style gained popularity due to its relatively low cost and ease of execution, making it accessible for both large-scale production and smaller, independent projects.
