A spiral binding machine is a device used to bind multiple sheets of paper together using a plastic or metal coil. This type of binding allows documents to lay flat when opened, making it ideal for reports, presentations, and manuals. The machine typically punches holes along the edge of the pages and then inserts the coil through these holes. These machines come in various sizes and capacities, suitable for both home and office use. Some models are manual, while others are electric, providing different levels of efficiency. Spiral binding is popular in educational and business settings for creating professional-looking documents.
