Comb binding is a method of binding documents using a plastic comb that has multiple rings. The comb is inserted through holes punched along the edge of the pages, allowing them to be easily turned and laid flat. This type of binding is popular for reports, presentations, and manuals due to its durability and flexibility. One of the key advantages of comb binding is that it allows for easy addition or removal of pages. Users can customize their documents by changing the order of pages or updating content without needing to rebind the entire document. This makes it a practical choice for many office and educational settings.
